    Full Text Available The needs for construction industry development are initially viewed from the broader perspectives of imperatives for infrastructure development and national development. All these are clearly more critical in developing countries. A non-exhaustive set of potential drivers and common barriers to construction industry development is identified from previous research. These suggest the usefulness of consolidating a cluster of recent proposals and exercises aiming at (a construction organization development in terms of an over-arching management support system model, as well as improved information and knowledge management; and (b project team development in the context of relationally integrated teams and supply chains, joint risk management and ‘technology and knowledge exchange’ in joint ventures, as well as longer term public private partnerships. These apparently disparate research thrusts are threaded together into a pattern that may inspire, if not feed, specific research and development (R & D agendas for construction industry development in different countries according to their own priorities, constraints and stages of infrastructure and national development.

    This study was conducted to verify technical feasibility in reusing drill cuttings originated in oil and gas exploration and production to produce concrete or mortar elements. It consisted of physical and chemical characterization of all items used to build field-cured cement samples - drill cuttings, cement and used aggregates; evaluation of resistance; environmental behavior and classification of the resultant materials. The results had demonstrated the reuse of drill cuttings is possible from both technical and environmental perspective and the ratio of concrete or mortar can be customized according to physical and mechanical needs of end products. In the civil construction elements can be built and used as road basis, ground-cement base, blocks and bricks and other non-structural elements. The application of these elements in E and P operations include containment walls for onshore wells, collecting stations, pipeline brackets, supports and hold-down anchors as well as road pavement and access. From the standpoint of chemical safety, the resultant elements made-up from drill cuttings had demonstrated no potential risk for hydrocarbon leaching (TPH), Polycyclic Aromatic Hydrocarbons (PAH's), Volatile Organic Compounds (BTEX), Phenols nor Metals. From these results many improvements in the E and P waste management can be established, bringing both economy and greater environment protection measures for the Oil and Gas Exploration and Production operations.

    The aim of this study is to show the results obtained from measuring energy expenditure (EE) during work, through portable devices, in a group of male construction workers. After defining cardio-respiratory parameters in laboratory, authors applied to all subjects an heart rate monitor for measuring the heart rate (HR) and, at the same time, a calorimeter for measuring energy expenditure (EE). To analyse data obtained, authors calculate the Relative Aerobic Strain (RAS), both for the measurements of EE and for HR detected. Results confirm that in many of the typical activities of construction industry, in particular in those characterised by an higher component of manual engagement compared to foreman, workloads are exceeding limits of the probable threshold fatigue (33% of RAS), both for energy expenditure than for HR measured.

  7. Waste Management in Industrial Construction: Investigating Contributions from Industrial Ecology

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available The need for effective construction waste management is growing in importance, due to the increasing generation of construction waste and to its adverse impacts on the environment. However, despite the numerous studies on construction waste management, recovery of construction waste through Industrial Symbiosis and the adoption of other inter-firm practices, comprised within Industrial Ecology field of study, have not been fully explored. The present research aims to investigate Industrial Ecology contributions to waste management in industrial construction. The waste management strategies adopted in two industrial construction projects in Brazil are analyzed. The main waste streams generated are identified, recycling and landfilling diversion rates are presented and waste recovery through Industrial Symbiosis is discussed. A SWOT analysis was carried out. Results demonstrate that 9% of the waste produced in one of the projects was recovered through Industrial Symbiosis, while in the other project, waste recovery through Industrial Symbiosis achieved the rate of 30%. These data reveal Industrial Symbiosis’ potential to reduce landfilling of industrial construction wastes, contributing to waste recovery in construction. In addition, results show that industrial construction projects can benefit from the following synergies common in Industrial Ecology place-based approaches: centralized waste management service, shared waste management infrastructure and administrative simplification.

    Full Text Available The Kingdom of Saudi Arabia (KSA has witnessed a huge increase in construction during the last two decades. However, many projects experienced time delays, cost overruns and the generation of massive amounts of waste. To address these challenges, lean construction has been introduced into the Saudi construction industry; however, it is still in its infancy. This study therefore investigates the current state of lean construction implementation in the construction industry in the KSA. The objectives are to identify: the types of construction waste, level of use of tools that support the implementation of lean construction, stages of application of lean methods, and the benefits of lean construction. To achieve these objectives, a structured questionnaire survey of 282 construction professionals was carried out. After the analysis of the collected data using mean score and Anova test, the following conclusions were made.  In the construction industry in the KSA, waiting is the most common type of waste, while Computer Aided Design (CAD is the conventional tool supporting the implementation of lean construction. Furthermore, the data suggests that lean construction is most commonly used in the construction stage of projects while customer satisfaction is the main benefit derived from lean construction practices. This study concludes that the level of implementation of lean construction in the KSA construction industry is increasing. The results will help benchmark the current state of lean construction implementation, which will enable the construction industry to identify strategies to implement lean construction in Saudi Arabia in accordance with their needs and project goals, to achieve better productivity.

    Full Text Available Indonesia’s construction industry is important to the national economy. However, its competitiveness is considered low due to the lack of success of its development strategy and policy. A new approach known as the cluster approach is being used to make strategy and policy in order to develop a stronger more competitive industry . This paper discusses the layout of the Indonesian construction cluster and its competitiveness. The archival analysis research approach was used to identify the construction cluster. The analysis was based on the I/O tables of the years 1995 and 2000, which were published by the Indonesian Central Bureau of Statistics. The results suggest that the Indonesian construction cluster consists of the industries directly involved in construction as the core, with the other related and supporting industries as the balance. The anatomy of the Indonesian construction cluster permits structural changes to happen within it. These changes depend on policies that regulate the cluster’s constituents.

    Full Text Available The implications for analysis of innovation in construction of theoretical developments in industrial organisation are considered in this research, as an attempt to outline a new approach to construction innovation incorporating the ideas found in knowledge based, technology centred models. The paper firstly summarises characteristics of the construction industry, focusing on their effects on innovation, before surveying some of the ideas about the sources of innovation and the expansion and application of knowledge. Construction can be seen as an industry with limited scope for knowledge externalities, where the procurement methods used by the industry’s clients do not pay for innovation. The following discussion uses recent developments in the research on the economics of innovation and industrial organization theory, such as research intensity and the endogenous sunk costs in competitive, fragmented, low research intensity industries. The effects on R&D of procurement methods and on industry structure are discussed, with a focus on the appropriability of innovations and the role of the client on the Heathrow Terminal 5 project. The paper concludes that the procurement methods used for building and construction projects appears to be a determining factor in the level of innovation in the construction industry

    Full Text Available Material is devoted to the phenomenon, rather new to the Russian economy, – to outsourcing in construction branch. Widely applied in foreign economic practice he acts at the same time both a micro, and macroeconomic factor. A conclusion of non basic assets from structure of real estate development company (especially – large and transfer of function on their management to other organizations, specializing in these services, allows to solve a number of problems. The tasks in construction solved by means of outsourcing, concerning preparation of necessary initial and allowing documents and control of work progress are considered in more detail. The company can concentrate on performance of the main functions, without being distracted by the organization of the accompanying processes. As a result outsourcing not only makes for it additional profit, but also increases its competitiveness. Also other advantages, and also shortcomings are considered. Outsourcing can be presented in different types and take various forms. In article the most widespread of them are considered: full, partial and advanced outsourcing. At external similarity of outsourcing and a subcontract are two various economic events. The main differences proceed from the purposes of their application and a procedure of control, and also consist in division of powers of the parties. There is also some other differences. The carried-out analysis shows advantages of the first before the second. Outsourcing in concrete types of construction activity is considered on the example of outsourcing of personnel. The Russian construction business gradually comes to understanding that outsourcing is a way of minimization of cumulative expenses, improvement of quality and reductions of time of execution of works.

    Full Text Available Sustainable construction is a way for the building and infrastructure industry to move towards achieving sustainable development, taking into account environmental, socioeconomic and cultural issues. Differing approaches and differing economic markets lead to different priorities. This paper presents the construction scenario of Malaysia and the developments in sustainable construction taking place in this country. Barriers to the implementation of sustainable construction are discussed. A list of recommendation was proposed to drive sustainable construction in this country. In conclusion, the status of sustainable construction in Malaysia is still in its infancy. The lack of awareness, training and education, ineffective procurement systems, existing public policies and regulatory frameworks are among the major barriers for sustainable construction in Malaysia. Besides the needs for capacities, technologies and tools, total and ardent commitment by all players in the construction sectors including the governments and the public atlarge are required in order to achieve sustainable construction in Malaysia.

  20. Industrial Disputes in the Construction Sector

    2012-11-01

    Full Text Available The Cole Royal Commission enquiry into the building and construction (abbreviated to ‘construction’ sector recommended controversial workplace-relation reforms for that sector. The recommended changes are likely to be enshrined in legislation within the year. The Commission drew on analyses of industrial disputes that focused, in the main, on quite recent experience. This paper attempts to give a broader historical perspective on disputes in that sector by considering the pattern of disputes for the entire post-World War II period. Accordingly, data on disputes and employees during the entire period are gathered from Australian Bureau of Statistics current and archived sources. These data are classified according to sector (construction versus non-construction and analysed. It is found that the strike rate has, on average, been greater in the construction sector than in the non-construction sector. However, there have been periods during which disputes in the construction sector have been relatively low. The most recent period was during the period of the Accord (1983-96, during which the strike rate in the construction sector fell relatively strongly. The analysis of this relatively broad historical period draws attention, among other things, to the possibility that the sort of strategies employed during the Accord years – strategies of cooperation and consensus building – may provide a more effective means of bringing industrial peace to the workplace relations scene of the construction sector than policies that are relatively confrontational.

    Reverse logistics in construction refers to the movement of products and materials from salvaged buildings to a new construction site. While there is a plethora of studies looking at various aspects of the reverse logistics chain, there is no systematic review of literature on this important subject as applied to the construction industry. Therefore, the objective of this study is to integrate the fragmented body of knowledge on reverse logistics in construction, with the aim of promoting the concept among industry stakeholders and the wider construction community. Through a qualitative meta-analysis, the study synthesises the findings of previous studies and presents some actions needed by industry stakeholders to promote this concept within the real-life context. First, the trend of research and terminology related with reverse logistics is introduced. Second, it unearths the main advantages and barriers of reverse logistics in construction while providing some suggestions to harness the advantages and mitigate these barriers. Finally, it provides a future research direction based on the review. © The Author(s) 2015.

    Full Text Available The paper describes research being carried out in relation to prefabricated high density affordablehousing under a grant from the Partnership for the Advancement of Technology in Housing(PATH and the National Science Foundation (NSF in the USA. The objective is to demonstratehow a new paradigm for the conceptualization and construction of buildings can be conceivedof as an entirely factory based process that creates advantages for construction through industrialsystems technology transfer. Our approach is intended to transform design methodologythrough demonstrating how alternative construction concepts, using entirely pre-manufacturedvolumetric units, can be adopted. This involves digital modeling that facilitates parametric variationsfor creating customized prefabricated products from design conceptualization through tofinal product delivery. The paper discusses key areas under investigation in relation to a manufacturingparadigm used in the automotive industry that integrates virtual prototyping and industrialmanufacturing systems. Our research explores a type of monocoque volumetric unit prefabricatedin steel, which will be pre-finished as part of a modular factory-built approach usingindustrialized methodologies that will facilitate customized manufacture of a high quality energyefficient product for affordable housing.The paper addresses the automotive industry methods of manufacture that have served increasedautomobile performance and economics through mass production for over a century. In starkcontrast, the building industry and in particular the housing industry is still a century behind.

  15. Sustainable Entrepreneurship in the Dutch Construction Industry

    Directory of Open Access Journals (Sweden)

    Rosalinde J.A. Klein Woolthuis

    2010-02-01

    Full Text Available This article discusses the strategies that sustainable entrepreneurs use to interact with their environment in the Dutch construction industry. The Dutch construction industry is under great pressure to move towards sustainability, and entrepreneurs are believed to be able to play a large role in this transition by introducing new products and new business practices. But how can entrepreneurs prosper in an environment that is not geared up towards such a change? And which strategies do they use to bend conditions in their favor? In this article we make use of the Market and System Failure Framework to analyze the pressures that entrepreneurs are confronted with when introducing sustainable innovations. We recognize that these pressures can be seen as bottlenecks, but that market and system failures can also create entrepreneurial opportunities. We interviewed 16 entrepreneurs in the Dutch construction industry to determine the influences they experienced from their environment and the strategies they use to deal with these. We conclude that we can distinguish between system building and following entrepreneurs, where the former aims to build a new system to challenge the old one, whereas the latter rather makes use of existing structures to build a business. We find that both strategies can be successful and that overall, the entrepreneurs confirm the belief that sustainability on people, planet and transparency aspects, can contribute very well to the long term profitability of the businesses the entrepreneurs are running. These in-depth insights into the influences from the context on the one hand, and the entrepreneurs’ strategic reactions on the other hand, contribute to our understanding of the interactions between entrepreneurs and the system context. This can help us to more effectively stimulate and support innovating entrepreneurs to contribute to the transition towards sustainability.

    The mortars can be considered as a mixture of the binders and aggregates with water, having capacity of the induration and adherence. Instead, it is suggested the production of mortars using civil construction waste, with plenty silicoaluminate, obtained in demolitions and reforms of build, and fly ash as material pozzolana, obtained of the combustion of mineral coal in fluidized bed boilers, in partial replacement of Portland cement. The civil construction wastes were benefited and characterized by X-ray spectrometry and X-ray diffraction. The fly ash was characterized by granulometric analyze and X-ray spectrometry. The mortars of the were prepared using the following compositions of RCC, 95, 90, 85, 80, 75 and 70%; CV of 0, 5, 10, 15, 20 and 25% e 5% of Portland CP II Z 32 cement. In all the compositions were put 0,8% of water and the rheological testing was used the same proportions residue (RCC e CV) with 35% water. The specimens were cured for 28 days and after were submitted physical trials of absorption, porosity and bulk density; mechanical trials of resistance to compression and analysis of X-ray diffraction and scanning electron microscopy. The results obtained show that the recycling of civil construction waste and the use of fly ash and RCC is a promising technique in production of mortars. (author)

    Full Text Available In the 1960s, a “new” marketing concept known as "four Ps marketing mix" appeared and shifted the focus from the product to the customer. The objective of the new concept was not only profit, and the means of achieving the objective expanded to include the entire “marketing mix”: product, price, promotion, and place (channels and distribution. Expenditures of marketing in a company should be explored from these mixes, because each mix would have an impact on the total marketing expenditures. These four mixes are the main aspects of marketing and thus, should represent almost all expenditures in marketing in a company. From this research it is discovered that the responding contractors have only average efforts to improve or innovate their service, mostly using the latest construction methods and management approach. Correlated to their policy in the fourth mix (Place, they are still national oriented and not international oriented in marketing their services, this may lead to the big question of their survival; their motivation to innovate is only average while their target market is only national market. Their attitude to use more intensive “fees” policy rather than both product innovation and promotion is also interesting. Big percentage of the responding contractors assumes these “fees” are regular marketing practices. This attitude may better be stopped to make the construction industry practices healthier. Attitude to use more product innovation and true promotion approach in marketing in construction must be encouraged systematically in the future, to improve competitiveness in the long term.

    As the dawn of the twenty-first century approaches, the current pattern of unsustainable, inequitable and unstable asymmetric demographic and economic growth has forced many segments of society to come together in facing a critical challenge: how can societies across the world meet their current basic human needs, aspirations and desires, without compromising the ability of future generations to meet their own needs? At the core of this challenge is the question: how can the human race maintain in perpetuity a healthy, physically attractive and biologically productive environment. The development path that we have been taking, in the past few centuries, has been ultimately detrimental to the health of our surrounding ecological context. We are consuming an increasing share of the natural resources available to use on this planet, and we are creating sufficiently large amounts of waste and pollution such that the earth can no longer assimilate our wastes and recover from the negative impacts. This is a result of a growing population as well as new technologies which make it easier for use to access natural resources and also require the consumption of more resources. Unsustainable technology has been the result of linear rather than cyclic thinking. The paradigm shift from linear to cyclic thinking in technological design is the crux of the shift from unsustainability to sustainability. This paper discusses the implications for the building design and construction industries. Strategies, technologies, and opportunities are presented to improve the sustainability of the built environment.

    Nowadays development of construction in Malaysia has been effect to the increasing of construction waste. Additionally, the production of construction waste from construction projects has given negative impact to the environment especially in illegal dumping activities. The increasing number of illegal dumping activities from construction projects in Malaysia gives a sign that Malaysian construction waste management needs to be concerned. To date, a comprehensive criterion for construction waste management, particularly for a construction project in developing countries is still not clearly defined. Therefore, construction waste management in Malaysia needs further research. The objectives of this paper are to explore illegal dumping activities, and discuss the contributory factors of illegal dumping activities. Hence, this research conducted an interview with expertise in the area of construction waste management in order to scrutinise illegal dumping activities in Malaysia. The data from semistructured interviews were analysed by content analysis. Findings from this research will help to find out the strategies to reduce the illegal dumping activities. The final result also expected to increase the awareness and better solution for reducing illegal dumping activities in construction projects among construction players.

    2012-10-01

    Full Text Available Human resources serve as the basis for development of the national economy, as a whole, and the construction industry, as its constituent part. The problem of inferior labor productivity within the framework of the national economy and its construction industry is considered in the paper. The author has identified the reasons why the productivity of the national economy and its construction industry is low. Low quality manpower is one of the reasons. Analysis of the statistical information has proven that the quality of the manpower in the construction industry is unsatisfactory. The author has also analyzed the relation between the construction industry development pattern and the quality of the manpower. Low manpower quality is a consequence of low personnel training and development expenditures assumed by local construction companies, if compared to the same assumed in the developed economies. Russian businesses do not invest any proceeds into their employees, as any employee may leave the company at any moment, and the employer will lose the investment. Therefore, the performance rate of the Russian construction industry cannot catch up with its western counterpart. The author also provides the analysis of the western personnel development concept. The author also makes his suggestions designated to reverse the unfavourable trend of the construction industry.

  16. Safety Management Practices in the Bhutanese Construction Industry

    Directory of Open Access Journals (Sweden)

    Kin Dorji

    2006-12-01

    Full Text Available The construction industry is considered as one of the most hazardous industrial sectors wherein the construction workers are more prone to accidents. In developed countries such as United Kingdom and United States of America, there is strict legal enforcement of safety in the construction industry and also in the implementation of safety management systems which are designed to minimize or eliminate accidents at work places. However, occupational safety in construction industry is very poor in developing countries such as Bhutan. This study investigates the prevalent safety management practices and perceptions in the construction industry in Bhutan. The study was conducted among 40 construction contractors and 14 government officials through method of questionnaire survey, interview and discussion. The result of the study revealed that there are many occupational safety problems in the construction industry in Bhutan, problems such as lack of safety regulations and standards, low priority of safety, lack of data on safety at construction sites, lack of competent manpower, lack of safety training, lack of safety promotion and lack of documented and organized safety management systems. Furthermore, the study also proposes some recommendations for safe construction in Bhutan.

    Henry Mwanaki Alinaitwe

    2009-06-01

    Full Text Available Engaging in lean construction efforts could prove to be highly rewarding for building firms in Uganda. However, lean construction is risky and can be disastrous if not properly managed. Lean production efforts in some other countries have not been successful due to the many barriers to its successful implementation. To enable sound lean construction efforts and to increase the chances of success in eliminating waste, a thorough investigation of the barriers is essential. This study presents 31 barriers and investigates their influence (strength on the success of lean construction initiatives. Structured interviews were carried out with technical managers of building firms to assess their perception of the barriers to lean production based on their experience at their firms. The strongest barrier is the provision of inputs exactly when required. Additionally, the barriers were ranked according to the ease of overcoming each. The easiest barrier to overcome is keeping the required items in the right place. Finally, a graphical aid is provided to enable decision makers to concentrate their efforts on the influential (strong, yet easy to overcome barriers. A lack of buildable designs and a participative management style for the workforce are the most important barriers to successful waste reduction in terms of strength and ease of overcoming. On the other hand, a lack of an organisational culture that supports teamwork, a lack of prefabrication and a lack of knowledgeable and skilled workers are regarded as low in strength, and at the same time difficult to overcome.

  1. Impact of Fragmentation Issue in Construction Industry: An Overview

    Directory of Open Access Journals (Sweden)

    Mohd Nawi Mohd Nasrun

    2014-01-01

    Full Text Available In general, fragmentation within the construction industry arises from two areas within the traditional construction process; the construction work process where the most significant division is in the separation of the design and construction phase, and the construction structure itself. The fragmentation process in traditional contracting practice further hinders the integration of construction knowledge among contractors, diminishing the opportunity for them to influence design decisions. When design professionals fail to consider as to how a contractor would construct the designed project results in scheduling problems, delays, and disputes during the construction process. Moving towards team integration is considered a significant strategy for overcoming the issue. Accordingly, this paper discusses the fragmentation issue in more detail including its definition, and causes and effects to the construction projects. It also explores that the team integration strategy alleviates scheduling problems, and helps avoid delays and disputes during the construction process, preventing harm to overall project performance.

A mechanism of inclusion of industrial construction objects into the Federal targeted investment programme is revealed. The sequence of the state expert evaluation of investment projects is determined, which optimises the design solutions aimed at minimising their estimated cost if the investment is made with the involvement of the Federal budget. Qualitative and quantitative criteria are systematised for the integrated assessment of the effectiveness of investment fund usage sent to industrial construction objects.Conclusion. The consistent implementation of the state investment policy is aimed at developing the scientific-technological and scientific-industrial potential of industrial construction by providing favourable conditions for effective innovation activity, selecting rational investment strategies and priority projects aimed at solving urgent problems of improving the competitiveness of construction. Successful implementation of the state investment policy in industrial construction largely depends on the effectiveness of investment design, starting from the accuracy of the formulation of the investment plan (idea, in which the interests of all participants in investment activities are concentrated and taken into account, and to the development of an agreed set of actions to complete the project. A unified register covering the data on the cost and results of investment projects is proposed to be created with the purpose of facilitating decision-making in the process of allocation of the Federal budget funds, planning of state capital investments and approval of project documentation for new industrial construction

    Full Text Available Despite the efforts for sustainability studies in building and infrastructure construction, the sustainability issues in industrial construction remain understudied. Further, few studies evaluate sustainability and benchmark sustainability issues in industrial construction from a management perspective. This study presents a phase-based benchmarking framework for evaluating sustainability practices use focusing on industrial facilities project. Based on the framework, this study quantifies and assesses sustainability practices use, and further sorts the results by project phase and major project characteristics, including project type, project nature, and project delivery method. The results show that sustainability practices were implemented higher in the construction and startup phases relative to other phases, with a very broad range. An assessment by project type and project nature showed significant differences in sustainability practices use, but no significant difference in practices use by project delivery method. This study contributes to providing a benchmarking method for sustainability practices in industrial facilities projects at the project phase level. This study also discusses and provides an application of phase-based benchmarking for sustainability in industrial construction.

Risk Management is a proactive decision-making process used to minimize and manage the risks in the most efficient and appropriate manner. However, most construction firms in Malaysia do not apply formal risk management in their projects. Thus, this study aims to identify the actual process of risk management that is being applied in the construction projects and to determine the effects of risk management implementation on the performance of the construction projects in terms of time and cost. The data were obtained from four case studies in Kuala Lumpur, Malaysia, through semistructured interviews. It was found that the implementation of risk management process in Malaysian construction industry is still at a low level, mainly due to the fact that most of the construction employees involved in risk management are not fully aware of the available risk management techniques that can be applied in construction projects.

    2013-01-01

    Working conditions in the construction industry have improved in many industrialized countries, but heavy physical work with recurrent exposure to chemical agents, dust, and climatic influences still represents considerable risk for construction workers and may affect their health. The aim of this review is to analyze available data of the literature on allergy-related respiratory and skin disorders with emphasis on a preventive appraisal in order to produce statements and recommendations based on research evidence. The most common agents involved in the construction industry as a cause of occupational asthma (OA) in industrialized countries are isocyanates, wood dust, resins, glues, cobalt, and chromium. Allergic contact dermatitis (ACD) is an immunologic cell-mediated response to a sensitizing agent and the most common sensitizing agents associated with construction workers are epoxy resins, thiurams and thiazoles, and chromates. Medical surveillance must consider individual risk factors such as differences in individual susceptibility and sensitization to agents at workplace. Once work-related disorder is confirmed, adequate fitness for work should be assessed for the worker impaired by health condition. A reliable diagnosis of an index case is a sentinel event that may reveal risks for workers with similar exposure, leading to a revised risk assessment at the workplace that should reduce the risk and prevent further cases.

    Full Text Available The quantity surveyors, in the present day construction industry, analyze cost components of a construction project in a scientific way and applies the results of the analysis to a variety of financial and economic problems confronting the developer and the designer. However, competence, in any sphere of work, can be a difficult concept to pin down, especially, when it relates to professional occupations where such roles are complex and involved diverse professionals in the built environment sector. This paper aims to investigate the competencies of quantity surveyors in the discharge of its professional duties by evaluating the effects of professional competency on quantity surveying practices in Nigeria. The study population comprised professional quantity surveyors who are in the private construction/consulting firms in Lagos State, Nigeria. Data were obtained to investigate the professional views on the quantity surveying profession, the roles of quantity surveyors in the construction industry and the need for professionalism and competencies in the surveying industry. Questionnaires were administered to randomly select 200 practicing quantity surveyors in Lagos state. Findings revealed that the major role of quantity surveyors in the construction industry is the preparation of the bill of quantity as it ranked 1st with RII value of 1.00; it was also discovered that quantity surveyors were in agreement with client service delivery as the first ethical standard that construction professionals should consider when performing their professional obligations in order to avoid project failure and over-cost. It is therefore recommended that the professional bodies and the academia should organize proper and adequate service trainings, workshops and seminars which will enhance the possibility of acquiring more skills and experience so as to improve competence in the discharge of quantity surveyors professional duties.

The importance of the SME sector is stressed showing that this group of companies plays significant role in the European economy. The main objective of the article is to define and show possible research areas connected with the introduction of Industry 4.0 concept into SMEs with the main focus on the construction sector. For this purpose, an analysis was made, based on the most recent literature, to point out actual needs in the SMEs sector in terms of its evolution into 4.0 level. What is more, the analysis was performed based on the most popular articles published in journals available in Thomson Reuters Web of Science Core Collection database regarding Industry 4.0 concept in the last decade showing the actual change of interest in this filed, taking into account possibility of usage of this concept in the construction and production sector. Authors tried to describe current knowledge regarding Industry 4.0 introduction for SMEs. Performed analysis showed that there is a wide spectrum of disciplines that are affected by the Industry 4.0 that needs to be examined considering introduction into SMEs. Study also showed that multidiscipline approach was not investigated so far to create special rules, procedures and methods and know-how designed for introduction of main principles of Industry 4.0 in the SME sector. Authors came to the conclusions that there should be more stress put into research in this field especially taking into account the huge potential which lies in SME sector in terms of global economic strength.

    South Africa has one of the highest HIV prevalences in the world, and compared with other sectors of the national economy, the construction industry is disproportionately adversely affected. Using data collected nationally from more than 57,000 construction workers, HIV infection among South African construction workers was estimated, together with an assessment of the association between worker HIV serostatus and worker characteristics of gender, age, nature of employment, occupation, and HIV testing history. The HIV infection of construction workers was estimated to be lower than that found in a smaller 2008 sample. All worker characteristics are significantly associated with HIV serostatus. In terms of most at-risk categories: females are more at risk of HIV infection than males; workers in the 30-49 year old age group are more at risk than other age groups; workers employed on a less permanent basis are more at risk; as are workers not having recently tested for HIV. Among occupations in the construction industry, general workers, artisans, and operator/drivers are those most at risk. Besides yielding more up-to-date estimated infection statistics, this research also identifies vulnerable sub-groups as valuable pointers for more targeted workplace interventions by construction firms.

    Since the introduction of BIM in Malaysia in 2009, the technology adoption rate is slow when compared to other countries of the world. Most of the construction companies in Malaysia have an insight on the BIM concept but are yet to implement it in the management of their construction projects. By the year 2020, the Malaysian government will make BIM mandatory, this makes it important to carry out research on the possible applications of the technology. A qualitative method of enquiry was used for this study in Klang Valley using semistructured interview. The responses received were analysed using Principal component analysis (PCA). The result of the analysis showed that “quantity take-off and estimation”, “clash detection and coordination”, “integration and collaboration of stakeholders”, and “design and visualisation” as the main applications of BIM in Malaysia presently. The implication of this findings is that the Malaysian construction industry productivity is likely to increase to meet the demand of the population through the implementations of BIM. More also, BIM technology is regarded as the future of construction industry, which makes it very important for the industry.

    Full Text Available One of the key areas being emphasis in ISO 9001 Quality Management System (QMS is performance measurement towards continual improvement. Among the primary measuring tools is quality cost approach. Quality cost has been well practice in manufacturing sector but slowly gain its importance in construction industry. In fact Project Management Body of Knowledge (PMBOK has reckoned quality cost as one of the tool and technique in few of its management processes. In view of such circumstances that has prompted an effort to undertake a study to ascertain the level of knowledge and practice on quality cost in Malaysian construction landscape. The targeted group of respondents was the personnel in the project management team. Capitalizing Construction Industry Development Board (CIDB National Electronic Tendering Initiatives (NETI road shows which were held in year 2007 throughout the country, the author was able to garner 263 respondents representing the project management team. Subsequently the data gathered from the completed forms were analyzed using Statistical Package for Social Science (SPSS software. General findings indicated that the level of knowledge and practice on quality cost among the project management team were relatively low. One of the main contributing factors was poor knowledge in the area related to quality cost. Despite of such scenario most of the respondents showed their interest in acquiring knowledge in the field of quality cost. Hence quality cost approach is at the infancy stage in Malaysian construction industry.

    This report for the International Energy Agency (IEA) made by Task 10 of the Photovoltaic Power Systems (PVPS) programme takes a look at urban building-integrated photovoltaics (BIPV) in the new residential construction industry. The mission of the Photovoltaic Power Systems Programme is to enhance the international collaboration efforts which accelerate the development and deployment of photovoltaic solar energy. The aim of Task 10 is stated as being to enhance the opportunities for wide-scale, solution-oriented application of photovoltaics in the urban environment. The report states that different types of building require different approaches to BIPV due to their associated varying dimensions and geometry. Several solutions are proposed to encourage the adoption and diffusion of BIPV by the new home residential building industry. These are divided into PV industry-based approaches and policy-based solutions. The former include end-customer focused policies, the identification of early adopters, the creation of product solutions that meet the needs of the building industry and standards and that the construction industry must be engaged in the design and planning stage of residential developments. Policy questions discussed include the provision of incentives, a planned approach to the demonstration of BIPV and the development of BIPV-specific policy.

    Full Text Available The wire ropes are used in different industrial fields. Their construction depends on the type of equipment and its purpose. Most frequently we meet with ropes at different transport and hoisting equipments and very freqently in the civil industry. For users characteristics are important which must meet requirements of the individual regulations and standards of the selection of wire ropes for the concrete equipment. The most important is the factor of safety being safeguarded by the corresponding bearing capacity of the rope. The service life of rope is interesting for the user, too, because of having an influence on the economy of the equipment on which the rope is working. These problems are solved by the grant project at our department . We are aimed at questions of the optimization of construction of wire rope with regard to their geometric construction and service life. Respectively on the basis of elaborated computer software eightstrand ropes of parallel construction were disigned and produced at the Drôtov ň a Hlohovec. The results of the fatigue tests confirmed their better qualitative properties, longer service life and economy advantages for users, too. Their using is possible and suitable on the new hoisting eguipment on the surface, in the undeground and in the hole drilling industry. By the application of the computer technique is also possible to improve the parametres of six-strands` construction of rope, the classic and parallel constructions, especially their bearing capacity. This fact follows from the knowledge that for the production of rope we use calculated diameters of wires, which secure better utilization of the metal cross-section of the wire ropes.

    Construction biotechnology includes research and development of construction materials and processes that make use of various microbes. The present technology landscape gives a perspective on how microbes have been used in construction industry as cement and concrete additives by analyzing patents filed in this technology arena. All patents related to the technology of interest published globally to date have been reviewed. The earliest patent filing in this technology domain was recorded in the year 1958 and the patenting activity reached its peak around mid to late 1990s. The early technology was mainly focused on microbial polysaccharides and other metabolic products as additives. Year 2002 onwards, biomineralization has taken precedence over the other technologies with consistent patent filings indicating a shift in innovation focus. Japan has been the global leader with highest number of patents filed on application of microbes in construction industry. Southeast University, China has topped the patent assignee list with maximum number of filings followed by Kajima Corp. and Shin-Etsu Chemical Co., Ltd. Most patent applications have claimed microbe based bio-products. Construction-related microbial technologies are mainly based on activity of different microorganisms such as urease-producing, acidogenic, halophilic, alkaliphilic, nitrate and iron-reducing bacteria. Sporosarcina pasteurii has been the most widely used microbe for biomineralization.

    Full Text Available The current financial and economic crisis has affected many sectors, and also the construction sector. The construction market has been and will be an important source of income for the entire Europe, totaling about 1.650 thousand billion euro, which is more than the GDP of Italy. Building no doubt brings significant percentage in the GDP of any European country, which of course is different from country to country. In Western European countries, the residential market is almost 50% from the construction market, while in Eastern European countries the majority is held by the civil and non-residential constructions. In addition, in the West the medium budget per capita spent on construction is 3-4 times higher than that spent in Eastern countries. But, according to previsions in the coming years the countries that will witness a growth, albeit small, will be the Eastern ones. The paper highlights the impact of the economic and financial crisis in the construction industry on a European and national level, as the sustainable constructions that may represent the sector’s future.

    Full Text Available The recent debate on innovation within an organizational setting has shifted focus toward discussing whether innovation is being adopted or being created. This shift is due to the failure of many innovation efforts and the fact that for each innovation creation or innovation adoption, different skills, resources, and cultures are needed to encourage each innovation. The objective of this article is to explore the type of innovation implemented by the construction participants. A conceptual model of innovation creation and innovation adoption was developed using four criteria: by justification of new ideas, by purposes, by activities involved, and by nature. Face-to-face questionnaires were conducted with developers, consulting firms, and contractors in Penang, Malaysia. The data were analyzed using descriptive analysis. Factor analysis was used to classify the innovation creation and innovation adoption. The results show that the construction participants in Malaysia are categorized as an innovation adopter. This result provides better understanding about the type of innovation implemented by the construction participants, in particular the contractors and the consulting firms. The results could also be used as a foundation for conducting future research to identify appropriate skills, knowledge, culture, and resources for such innovations.

    2012-11-01

    Full Text Available In recent years culture has become one of the most studied topicsin project management research. Some studies have investigatedthe infl uence of culture at different levels – such as nationalculture, industry culture, organisational culture and professionalculture. As a project-based industry, the construction industryneeds to have more insight concerning cultural issues at theproject level and their infl uence on the performance of constructionprojects. Few studies, however, have focused on culture at theproject level. This paper uses a questionnaire survey to determinethe perceptions of Chinese contractors about the impact of projectculture on the performance of local construction projects. This isaugmented by a series of in-depth interviews with senior executivemanagers in the industry. The fi ndings indicate that specifi c projectculture does contribute signifi cantly towards project outcomes.In particular, goal orientation and fl exibility, as two dimensionsof project culture, have a negative statistical correlation withperceived satisfaction of the process, commercial success, futurebusiness opportunities, lessons learnt from the project, satisfactionwith the relationships, and overall performance. This paper alsoindicates that the affordability of developing an appropriate projectculture is a major concern for industry practitioners.

    Full Text Available This article presents the teaching approach of different universities in the state of Rio de Janeiro regarding the dissemination of two civil construction learning paradigms: BIM and Lean Construction. The article’s main purpose is to investigate the learning systems of the two techniques for the benefit of the construction industry, as well as to evaluate their level of recognition. The principal results show that civil engineers graduates acquire little or no knowledge of both techniques, which may become a barrier to their professional evolution and especially to their involvement with public works projects.

    Full Text Available This paper examines the relationship between innovation and productivity improvement in the construction industry. It is argued that this relationship is not well understood due to lack of in-depth understanding of innovation in construction. To overcome this obstacle, the authors present a multi-dimensional innovation classification system which aims at better defining and classifying what is meant by innovation in construction. The use of this classification system is demonstrated by applying it to a database of 500 innovations reported by the construction alliance, the Stronger Christchurch Infrastructure Rebuild Team. The results clearly demonstrate the diversity of types, degree of novelty and performance improvement benefits among construction innovations. Such diversity means that the impact of the reported innovations on productivity and performance are of different levels of significance. The classification system developed in this study can be used by construction organisations and alliances in the future to develop more detailed methods of calculating innovation performance indicators, based on the innovation type, novelty and benefits factors. By using this system, they can also put in place mechanisms to influence the types of innovation developed in their projects with the aim of maximising their productivity performance.

  3. Strategies for Minimizing Corruption in the Construction Industry in China

    2006-12-01

    Full Text Available Corruption is a social phenomenon deep rooted in the history of mankind. It is similar to other kinds of crime which are likely to occur in procurement of works by governments and local authorities, due to the large amount of money involved in a single transaction and the difficulty in monitoring project expenditure. Therefore, it is necessary to develop strategies to minimize any corruption risks and corrupt behaviour in procurement of construction projects. The aim of this paper is to review the current corruption prevention practices in China’s construction industry and suggest ways for improvement. To collect useful and insightful information, desktop studies, focus-group workshops and face-to-face interviews were conducted with supervisory and construction officers at different levels – state, province and municipal in China, who have direct responsibilities and experience in cracking down construction corruption. It was found that corruption happens in different forms during any stage of construction project procurement, and the current anti-corrupt practices are reactive rather than proactive. It was also found that improvements on the legal system, inspection strategies and processes, and promotion of ethical culture are all required. Based on the research findings, corruption prevention strategies were developed. The paper concludes that institution of random and regular checks, severe punishment and prosecution to corrupt personnel, and promotion of a healthy and clean construction culture are all necessary to mitigate the scourge.

    Full Text Available While environmental sustainability has been the subject of much debate in the last decade, it was not until recently that attention started to shift towards human resource management as an enabler for sustainability.  Yet, this is still a relatively under researched area.  Much is still unknown about the role of an individual worker in contributing towards sustainable development.  This paper addresses the gap by proposing a framework to measure sustainability competencies of employees within the construction industry sector.  As part of the framework, four proficiency levels together with relevant descriptions are defined for a total of eight sustainability competencies.  Suggested proficiency levels are then mapped to main construction related jobs based on the framework.  An example is also given to illustrate the manner in which competencies should be assessed.  This framework is original and of practical use to construction managers and human resource practitioners.

    Full Text Available Clearly written communication aids the understanding of construction contracts, resulting in less disputation. Past research, using opinion surveys rather than objective criteria, shows that construction contracts lack clarity and standard forms have become complex over time. The study outlined in this paper uses three objective measures of clarity developed by linguists to establish the readability of construction contracts. In addition, thirty industry professionals participated in a Cloze Test which measured the level of comprehension of clauses concerning disputes. The study verifies that contract conditions are very difficult to read, with college level reading skills needed to comprehend half of the clauses. However, the hypothesis that standard forms have become complex over time was not supported by the study. The study establishes a linear relationship between readability and comprehension, proving the hypothesis that improved readability increases the comprehension of a contract clause.

    The presence of chemical agents in construction is certainly relevant in terms of quality, quantity and toxicity. Their manipulation can result in potential exposure as inhaled and/or through the skin. It is therefore possible and necessary to identify a list of substances to be considered relevant for the risk assessment and the possible environmental monitoring to verify the adequacy of the estimate made. The many variables inherent in construction make it extremely difficult to apply the usual methods of the industrial hygiene because it would not very significant conclusions in terms of space-time representation. SIMLII in one of its guidelines have proposed a "indexes" method that can provide useful information to the figures of prevention for the actions of their competence. The subsequent introduction of the REACH Regulation and exposure scenarios may help to further sharpening the assessment of chemical hazards in construction.

    Full Text Available As demand on building construction projects rises, various procurement methods have been adapted to suit with unique project requirements. However, poor industry performance and rapid developments within it indicate the need for a research on the procurement systems in the industry. In order to explore the development of procurement systems in Malaysia, a discussion on different economic phases which influence the routes of procurement systems and its evolution in Malaysia's construction industry is initiated. Subsequently, based on a questionnaire survey collected from 73 public and 68 private parties, the significant and dominant role of traditional procurement system used by both the public and private sectors in Malaysia can be confirmed. Further, compared to the public sector, the private sector is observed to be more aggressive in adapting alternative systems such as design and build (D&B and Turnkey. Further elaboration on the research findings is covered in the discussion section.

    Full Text Available Subcontractors perform most of the construction works and their effect on industry are apparent in different activities of construction. Therefore, subcontractors need more attention from government and contractors union. The aim of this paper is to identify, evaluate, and rank factors that influence safety performance of subcontractors in the Gaza Strip (Palestine according to their relative importance. The study concluded that reported accident rates will decrease among subcontractors and their workers if new workers are trained well in the work site and they are informed about dangerous places, and if a workable safety plan is well preplanned. The results also showed that reported accident rates increased among subcontractors when using old, unsafe equipment and due to the complexity or difficulty in the construction sites features. Owners and general contractors need to stipulate strict clauses for safety in the contract for improving safety record of subcontractors. Construction workers must receive proper job related safety and health training with a safety logbook. It is recommended that the subcontractors and workers should attend continuing safety programs on regular basis as part of their perquisite to work in construction sites.

    As a part of a VHTR economic analysis, we have studied the VHTR construction cost and operation and maintenance cost. However, it is somewhat difficult to expect the exact cost due to insufficient reference data and experience. As a result, we propose quantitative analysis techniques for ripple effects such as the production inducement effect, added value inducement effect, and employment inducement effect for VHTR 600MWt x 4 module construction and operation ripple effect based on NOAK. This paper presents a new method for the ripple effect and preliminary ripple effect consequence. We proposed a ripple effect analysis method using a time series and inter-industry table. As a result, we can predict that a 600MWth x 4 module VHTR reactor construction will bring about a 43771 employment effect, 24160 billion KRW production effect, and 4472 billion added value effect for 22 years. It is necessary to use the sub-account values of an inter-industry table to obtain a more precise effect result. However, the methodology can be applied with minor modification to another reactor type.

    Full Text Available Many studies have shown that the construction industry one of the most hazardous industries with its high rates of fatalities and injuries and high financial losses incurred through work related accident. To reduce or overcome the safety issues on construction sites, different safety programs are introduced by construction firms. A questionnaire survey study was conducted to highlight the influence of the Construction Safety Factors on safety program implementation. The input from the questionnaire survey was analyzed by using AIM (Average Index Method and rank correlation test was conducted between different groups of respondents to measure the association between different groups of respondent. The finding of this study highlighted that management support is the critical factor for implementing the safety program on projects. From statistical test, it is concluded that all respondent groups were strongly in the favor of management support factor as CSF (Critical Success Factor. The findings of this study were validated on selected case studies. Results of the case studies will help to know the effect of the factors on implementing safety programs during the execution stage.

    Versailles-Satory (France) May 31, 1995 - Giat Industries has just obtained a contract from the European Southern Observatory (ESO) for the construction of the primary and tertiary mirror supports and the positioning apparatus of the world's largest optical telescope. This contract, worth almost 140 million francs, represents over 100,000 hours of work. It was won by Gitech, a division of Giat Industries, in collaboration with the Sfim group, following an international competition between the largest European groups in the space field. Gitech is charged with the development of civil and military industrial equipment for the Giat Industries group, in particular in high technology fields. The VLT (Very Large Telescope) will be installed in Chile before the year 2000; the delivery schedule provides for reception of the first assembly in May 1997. It will consist of four telescopes of 8.2m diameter, providing, in its most powerful configuration, a close-up view of an object measuring one meter on the surface of the moon. The cell, built by Gitech, is one of the key parts of the telescope. It mainly consists of a very rigid metal structure and an electro-hydraulic system of more that 200 hydraulic jacks and 150 electrically-controlled jacks linking the metallic structure to the mirror. This structure, produced to an original design of laser-welded steel chambers, weighs less than 10 tonnes and will support over 37 tonnes of mirror and equipment, while guaranteeing precise positioning to within a micron. The electro-hydraulic jack system, manufactured in collaboration with the Sfim group, will support and position the mirror, and correct its geometry by applying a precise distribution of forces to its rear. The assembly is designed to meet the requirements of para-seismic safety. Gitech is also producing the computerised control system to ensure the operation and the reliability of the assembly.

    Full Text Available There has been an influx of foreign labourers in Malaysia over the past decade due to sustained economic growth and a limited labour market. As a long term measure to ensure sustainable growth as well as to minimize socio-economic implications, a medium to longer-term policy on foreign workers will be devised with the goal of reducing overdependence on foreign workers while attracting more skilled and trained professionals. In order to reduce the number of foreign workers, the government has encouraged the implementation of an IBS. An Industrialized Building System (IBS is a construction system in which the components are manufactured in a factory, on or off site, positioned, and assembled into complete structures with minimal additional site work. This research has been carried out to discover trends, whether decreasing or increasing, in the employment of foreign labour in the Malaysian construction industry with reference to the Immigration Department of Malaysia. Additionally, interviews with construction labourers at IBS sites and conventional sites were carried out to identify the number of foreign labourers that are used in such projects.

    Consequences of traumatic brain injury underscore the need to study high-risk groups. Few studies have investigated work-related traumatic brain injuries (WrTBIs) in the construction industry. To examine WrTBIs in Ontario for the construction industry compared to other industries. A retrospective study of individuals who sustained a WrTBI and had a clinical assessment as an outpatient at a hospital-based referral centre. Data were collected for a number of factors including demographic, injury and occupation and were analyzed according to the Person-Environment-Occupation (PEO) model. 435 individuals who sustained a WrTBI. There were 19.1% in the construction industry, 80.9% in other industries. Compared to other industries, individuals in the construction industry were more likely to be male, to not have attained post-secondary education, and experience multiple traumas. WrTBIs in the construction industry were commonly due to elevated work. The construction occupations involved included skilled workers and general labourers, and compared to other industries, WrTBIs occurred most often for those employed for a short duration in the construction industry. Construction industry workers experience serious WrTBIs that are amenable to prevention. Use of the PEO model increased our understanding of WrTBIs in the construction industry.

    2010-01-01

    This paper reports on findings of a study on the performance of two units of a Horizontal Sub-Surface Flow Constructed Wetland (HSSFCW) units in treating wastewater effluent from a tannery industry. One of the HSSFCW units was planted with macrophytes, while the other was used as a control (without plants). Wastewater was fed into the wetland units at the mean flow rate of 0.045+/-0.005 m(3)/day. The studied parameters were chromium, turbidity, salinity, Total Dissolved Solids (TDS), Electric Conductivity (EC), pH and temperature. The mean Hydraulic Retention Time (HRT) was 1.60 days (in the control) and 1.80 days (in the vegetated) units, obtained as a ratio of the volume of the wastewater and the volumetric flow rate of wastewater through the units while taking into consideration the porosity of the media. The vegetated HSSFCW exhibited higher chromium removal efficiency (99.83%), than the control unit with the removal efficiency of 92.53%. High chromium removal was associated with both high temperature as well as high pH values in the HSSFCW units. The reduction in turbidity was found to be 71% in the vegetated wetland unit while the corresponding value for the control unit was 66%. Results obtained indicated low reduction efficiencies of both EC (0.3% in the vegetated unit and 1.6% in the control unit) and salinity (11% in the vegetated unit and 22% in the control unit) in the two mesocosms. Generally, however, the study demonstrated that constructed wetlands can be used as an option for improving the quality of tannery effluents especially in the removal of chromium. Chromium removal might have been effected by, among others, gravitational settling of solids and formation of co-precipitation with insoluble compounds as well as adsorption on the substrates and plant surfaces.

    Full Text Available Construction industry plays very important role in development of any country. The development of construction industry depends to a larger extent on quality of construction productions and projects. Quality of construction productions and projects is linked with the implementation of QMS (Quality Management System in construction organizations. ISO certification is one of the QMS which has been adopted in manufacturing and construction industry at the global level. The construction companies of developing countries have reaped many advantages from the effective implementation of ISO standards. The rate of adoption of ISO standards has remained slow in the construction sector of some developing countries like Pakistan. This paper presents the literature review of ISO in global construction industry. It highlights the advantages, disadvantages and barriers faced by construction companies in the implementation of ISO standards. This study also investigates the level of adoption of ISO standards in construction and manufacturing companies of Pakistan through a questionnaire survey. It presents the comparison of ISO standards\\\\\\' adoption in both construction and manufacturing sectors. The paper puts forward some suggestions and recommendation for the better adoption and improvement of ISO implementation in the construction sector of Pakistan. This study emphasizes that construction companies of Pakistan should learn from the benefits reaped by the construction companies of developed countries and take appropriate measures for implementing ISO standards. It also suggests that public sector clients should make it obligatory for the contractors and consultants to have ISO certification before awarding the works in order to enhance the the adoption of ISO standards in construction sector.

    Full Text Available This article aims to map out the level of social performance measurement of Czech companies, i.e. what social performance indicators companies monitor and what information they provide to their stakeholders and to construct alternative corporate social performance indicators. Based on an analysis of 24 corporate voluntary reports and results of an empirical research performed among 79 large companies operating in the manufacturing industry, it was found that companies partially monitor their social performance, but from the perspective of international standards (e.g. Global Reporting Initiative, International Federation of Accountants it is still insufficient. Czech companies usually provide only absolute numbers which disguise real trends and do not allow year on year comparison or comparison with other companies. Czech companies should provide a comprehensive picture of their overall performance, they should not focus only on financial indicators based on accounting data, since it is known that the performance measurement based only on financial and economic performance does not lead to long-term success and sustainability of organizations. Companies should monitor more their impact on society within which they operate. Proposed corporate social performance indicators in a measurable and thus manageable way express social issues.

    Full Text Available As extensive resources are expanded in transferring knowledge from universities to undergraduates, it is important for them to enter the workforce upon graduation to enable the knowledge to flow to the industry. The aim of this study is to investigate the extent to which knowledge flow is disrupted because graduate women are not entering the Singapore construction industry to ensure its sustainable growth. This study used a structured questionnaire, with data collected from 116 construction-trained graduate women via postal survey. Results show that 58% of them chose not to enter or are considering leaving the construction industry. The disruption in knowledge flow is due to better prospects in other industries (pull factor and poor job conditions within the construction industry (push factor. To retain graduate women in the construction industry, it is recommended that employers: introduce flexible work schedule; allow graduate women to work from home; and give them the same opportunities as their male counterparts.

  14. Potential Implementation of Green Prefab System in Malaysian Construction Industry

    Directory of Open Access Journals (Sweden)

    Md Azree Othuman Mydin

    2013-09-01

    Full Text Available Prefab system can be defined as a building process in which sections of modules of the structure are assembled at a remote location, and then transported to the construction site. This type of construction technique is very lucrative and often makes it possible to complete a building project in as much as half the time required for more traditional methods. Prefab construction is frequently employed with the construction of new houses; the strategy can also be used with other buildings. The outstanding ability behind prefab construction is based on the idea that by using standard components that are partly assembled on a manufacturing floor, there is less time involved in the actual construction process. The modules are transported to the site, using freight transportation. At the site, the modules are unloaded, moved into position with the aid of heavy machinery, and connected to form a single building. Along with the fast assembly, prefab construction could often save a great deal of money on the building construction. By using standard patterns, the building materials are pre-cut at the manufacturing site. This eliminates an enormous deal of the waste in timber and other components that can crop up during the process of building. Consequently, a prefabricated house with three bedrooms is likely to cost significantly less than a three bedroom dwelling that is constructed from scratch at the building site. This paper will discuss the potential of green prefab construction in Malaysia.

    Full Text Available Background: The construction industry in South Africa has a lot of potential but its performance is still restricted by numerous internal and external challenges. Unless these challenges are identified and understood better, further growth of this industry is likely to be hindered, which has negative economic implications for the South African economy.Objectives: This study investigated supply chain bottlenecks faced by the construction industry in South Africa. It also discussed solutions for addressing the identified bottlenecks in order to facilitate the continued development of supply chain management in the construction industry.Method: The study used a qualitative approach in which in-depth interviews were held with purposively selected senior managers drawn from the construction industry in South Africa. Content analysis using ATLAS.ti software was employed to identify the themes from the collected data.Findings: The findings of the study showed that supply chain management in the construction industry in South Africa is constrained by five major bottlenecks: skills and qualifications, procurement practices and systems, supply chain integration, supply chain relationships and the structure of the construction industry. Recommendations for addressing each of these five challenges were put forward.Conclusion: The study concludes that both awareness and application of supply chain management in the construction industry in South Africa remains inhibited, which creates opportunities for further improvements in this area to realise the full potential of the industry.

    Full Text Available Building Information Modelling (BIM is a revolution of technology and a process that transformed the way building is planned, designed, analysed, constructed and managed. The revolution of technology and process could increase the quality of construction projects. The knowledge of BIM has been expanding in many countries including Malaysia. Since its inception, the use of BIM has broadened up widely with different purposes. The aims of this paper is to investigate the BIM implementation and uses in Malaysian construction projects. The methodologies adopted for structuring this paper are by using literature review and semi-structured interview with construction players that have experienced and being involved in projects using BIM. The purpose of literature review is to illustrate on the pervious research on the subject matter. Meanwhile, the purpose of interviews is to explore the involvement of construction players, years of experience in projects using BIM and BIM uses in construction projects. The findings revealed that BIM has been implemented in Malaysia since 2007 by various construction players, which are client, architect, C&S engineer, M&E engineer, QS, contractor, facilities manager and BIM consultant. The findings also revealed that BIM is used for project’ visualisation, improving project design, detecting design clashes, quantity take off and operation and maintenance. Further work will be focused on the current practices of construction players in projects using BIM.

    Full Text Available In this article, the procedure of identification of organizational and technological reliability is described. This methodology is applicable both to separate functional areas and to all industrial enterprises. Its objective is to assess the expediency of reorganization. The objective of this scientific research is the substantiation of reorganization of an industrial enterprise. Multivariable models, or convolutions, were used as research methods. According to the RF law, industrial enterprises are divided into four functional areas, each of which is assessed on the basis of multiple criteria. Assessment of organizational and technological reliability requires a multi-parameter model. Its axes correspond to the number of evaluation criteria. The set of criteria designated for the assessment of organizational and technological reliability is identified on the basis of the homogeneity of trend indicators designated for centripetal and centrifugal models. The axes of a multi-parameter model represent real and benchmark values. The unit serves as the benchmark value; it is the maximal value of this parameter. The formula based on average values shall be used to determine the total value of the above parameters. The authors have also generated a model of organizational and technological reliability of industrial enterprises. It is noteworthy that assessment of organizational and technological reliability of an industrial enterprise requires a concentric multi-layer model developed through the application of the convolution method.

    Full Text Available Construction is traditionally a male industry. Women have long had difficulties entering or advancing their career in construction. Evidence shows that a diversified workforce with gender balance will bring about higher levels of productivity. Despite the importance of this issue, there have been limited studies on women’s career development in construction. This study aims to investigate women’s career development in the Australian construction industry, with objectives to evaluate the challenges and success factors of women’s career development in the construction industry and provide strategies for narrowing the gender imbalance. A mixed approach of questionnaire survey and interview were conducted with female practitioners in the construction industry. Forty-three completed questionnaires were received and 10 interviews were conducted. Stress, family-work balance, and negative perception towards women in construction were the top three challenges identified. Dedication, determination, and independence were the top three success factors of women in construction. This study recommends construction employers consider providing personal development programs and flexible working arrangement for their female employees. Significance of this study lies on contributing to understanding women’s career development in construction. Findings will be useful for government and professional institutions to promulgate strategies for advancing women’s career development in construction.

    Full Text Available With the growing competition, many construction organizations attempt to improve their productivity, quality, and efficiency. Construction waste management, by means of reverse logistics, becomes a key issue to improve the productivity, and raise the company’s green image. In this study, four reverse logistics methods-direct reuse, remanufacturing, recycling, and landfill-are considered to manage construction and demolition (C&D waste. Two factors (economic and site-specific with their 15 sub-factors affecting the decisions to implement the reverse logistics are examined. The hierarchy model of reverse logistics decisions, developed through the analytic hierarchy process, reveal the importance of the economic factor over the site-specific factor. It is suggested that the transportation cost, the processing cost, the specific sorting technology, and the limited project time must be first considered before making decisions on reverse logistics plans. The construction company can utilize the developed hierarchy model to decide on the most appropriate reverse logistics plan to achieve the best benefits.

    Directory of Open Access Journals (Sweden)

    Svetlana Nikolayevna Kotlyarova

    2016-12-01

    Full Text Available The issues of the dependence on imports and import substitution are the major factors in the development of the domestic economy. The subject matter of the research is the dependence of construction industry on imports in the area of foreign technology, it is aimed at identifying the scope of the problem and justifying the mechanisms to overcome it. The article substantiates the relevance and importance of import substitution in the production of construction materials and equipment. Import substitution in the construction industry can be implemented in two main ways, requiring different approaches in supporting and encouraging. Firstly, there is the substitution of products used in construction, aimed at minimizing the risk of disruption of the supply of imported products for construction purposes and the predominant use of domestic analogues of imported products for construction purposes. Secondly, there is the substitution in the technologies of production of goods used in construction, focused on stimulating the development of the domestic production of competitive products and technological and managerial modernization of the construction materials industry, construction industry. The process of import substitution in the construction industry have a number of limitations. In this connection, the article discusses the opportunities and constraints for import substitution. A special attention is paid to the practice of the formation of regional construction clusters as a tool of implementing the policy of import substitution. The purposes and principles of the development of clusters, sources of initiatives, used systems of transfer and knowledge and innovations are considered critically. The conclusion is made about the need for the strategic development of new products for the construction market and domestic research and development projects within the framework of cross-sectoral clusters.

    This study sought to understand the prevalence of harmful alcohol use in a sample of Australian male construction industry apprentices and also examine alcohol-related violence. Although previous Australian research indicated that 45% of construction industry apprentices had Alcohol Use Disorders Identification Test scores indicative of harmful drinking, the current study identified that 66% of construction industry apprentices were drinking at harmful levels. It also identified positive correlations between harmful drinking behavior and alcohol-related violence (and precursors of violence such as verbal abuse). The article notes the role of masculine identity in alcohol consumption, particularly as it relates to the male-dominated construction industry. The article concludes by making recommendations for implementation of preventative education campaigns in apprentices' workplaces (or in training colleges), as it provides opportune settings to focus on high-risk groups, which are otherwise often difficult to access.

    Full Text Available This research explores the tenets of safety leadership within the Australian construction environment. The scope of this research aims to establish a universal definition of safety leadership and how it differs from other leadership disciplines. The literature review into this topic was governed by the parent disciplines of Safety and Leadership.  Gaps were identified in the literature that indicated safety leadership is not a well-defined concept and much of the work into safety leadership has been borrowed from other schools of leadership. An exploratory research methodology was utilised which rooted the research into the post-positivist methodology. There were twenty interviews conducted for this research, with participants coming from various leadership positions across multiple construction projects around Australia. Findings detailed a saturation of data that allowed for an empirical definition towards safety leadership to be established. As a person’s scope of responsibility increases, their view of safety leadership becomes synonymous with leadership; although differences do exist. These differences were attributed to the importance of demonstrating safety and working within the legal framework of Australian construction projects. It is proposed that this research offers a substantial contribution to knowledge, based upon a well-defined definition into safety leadership.

    2008-12-01

    Full Text Available The UK construction industry is one of the largest employers, positioned as the country’s top employer with over two million employees and projected to continue growth as far as 2011. However, it is facing ongoing skills shortages in a number of professional areas and tends to lack an ethnic diversity of workers compared to the White community of workers across the whole economy. The government’s Ethnic Minority Employment Task Force shows that for any given level of qualification, a Black or ethnic minority person is less likely to be employed, than a similarly qualified White person. Current research into issues surrounding ethnicity, from academia to employment is scarce, particularly in entry and process development within the construction industry. The aim of this paper is to outline the findings from perceptional and experiential barriers of Black and Minority Ethnics (BMEs students and employees, in order to identify perceptional and actual barriers that lead to the under-representation of BMEs within the construction industry; and also to suggest how better knowledge flow mechanisms could lead to a more balanced development, particularly in terms of ethnic diversification in the UK construction industry. The aim was achieved by adopting qualitative and quantitative methods including questionnaire surveys of undergraduate students in a construction related program, employees working within the construction industry and interviews with company directors and human resource managers. The image of the construction industry is found to be one of the major barriers for entry into the industry. Language and cultures form additional barriers for a range of ethnic groupings. Support, in the form of recruitment events, training, mentoring, professional networking, as well as work placement and experience schemes, can smooth entry, retention and progression within the construction industry.

    Ethics is becoming one of the most important requirements for successful business in the 21st century. The construction industry cannot be exceptional from this trend. However construction ethics management requires different approaches from other industries, as the products of the industry are construction projects which are completely different from mass production. Contractors and designers are two major participants in construction projects. The roles and responsibilities of these two project stakeholders decisively influence all aspects of construction project. Practically ethical perceptions of contractors and designers are one of main aspects to be considered for the effective and efficient management of ethics for the construction industry. This research has investigated the ethical perceptions of contractors and designers in the China construction industry. A questionnaire survey which contains 15 ethical issues and 6 demographic factors has been conducted. 170 construction professionals from construction companies and consulting companies have been participated in this survey. These 15 ethical issues are ranked in terms of seriousness, frequency and importance for both contractors and designers as a single group to understand the overall perceptions in the industry. The analysis has also been conducted for contractors and designers respectively to make comparisons between them. The top three serious ethical issues in the industry are ‘Bribery and corruption’, ‘Failure to practice whistle-blowing’ and ‘Improper bidding practices’. Contractors and designers showed similar outcomes for the top five important ethical issues. But for the middle ranged ethical issues, they showed some differences. Further researches are required to identify the causes of the similarity and differences.

    2014-02-01

    This paper analyzes the severity of workplace accidents involving electricity in the Spanish construction sector comprising 2,776 accidents from 2003 to 2008. The investigation considered the impact of 13 variables, classified into 5 categories: Personal, Business, Temporal, Material, and Spatial. The findings showed that electrical accidents are almost five times more likely to have serious consequences than the average accident in the sector and it also showed how the variables of age, occupation, company size, length of service, preventive measures, time of day, days of absence, physical activity, material agent, type of injury, body part injured, accident location, and type of location are related to the severity of the electrical accidents under consideration. The present situation makes it clear that greater effort needs to be made in training, monitoring, and signage to guarantee a safe working environment in relation to electrical hazards. This research enables safety technicians, companies, and government officials to identify priorities and to design training strategies to minimize the serious consequences of electrical accidents for construction workers.

    2011-03-01

    Full Text Available Productivity growth is strongly correlated to economic growth and increases in welfare. This fact also holds true at the industry level and is particularly true in the NZ construction industry, since productivity growth in this sector may have significant effects on the affordability of housing in the country. In recent years construction in NZ has been subjected to a series of reports that have either highlighted ‘failure’ to grow productivity or have exhorted the industry to improve its ‘poor performance’.  However thus far little by way of analysis has gone into the productivity figures that have been quoted, nor has much been done to explain and justify if or why these figures are correct or incorrect.This research seeks to deconstruct construction productivity figures in NZ and explain the patterns over recent years of ‘poor performance’ in comparison with other industries.  As such it will examine the nature of the NZ construction industry and analyse the historic statistics related to its labour productivity. This will provide an overall understanding of the sector as well as those extraneous factors that may have significant influences on the NZ construction sector.The research found that while factors influencing inputs of labour productivity measure such as labour and material costs remained stable, factors impacting the corresponding outputs such as house and land prices, value of work in Non-residential and Infrastructure construction grew significantly between 1997 and 2007. Given the positive skewing effect of standard economic indicators (inflation etc on construction labour productivity figures, the relatively poor performance of construction is worrying for the industry. The paper concludes by demonstrating labour productivity in construction is significantly worse performing than previously suspected.

    The construction industry is a demanding work environment where employees' work-family conflict is particularly prominent. This conflict has a significant impact on job and family satisfaction and performance of employees. In order to analyze the dynamic evolution of construction industry employee's work-family conflict between work and family domains, this paper constructs a bi-directional dynamic model framework of work-family conflict by referring to the relevant literature. Consequently, a system dynamics model of employee's work-family conflict in the construction industry is established, and a simulation is conducted. The simulation results indicate that construction industry employees experience work interference with family conflict (WIFC) levels which are significantly greater than the family interference with work conflict (FIWC) levels. This study also revealed that improving work flexibility and organizational support can have a positive impact on the satisfaction and performance of construction industry employees from a work and family perspective. Furthermore, improving family support can only significantly improve employee job satisfaction.

    2017-11-01

    Malaysia construction industry has been growing continuously with double-digit growth for the past two decades. There are many issues surrounded the industry such as delay in delivery, cost overrun, quality and safety. In bumiputera contractor’s context, the literature review found that 32 issues were encountered in the construction project. These issues can be handled properly with the application of risk management. According to previous researchers, application of risk management in Malaysia construction industry is at the low level where it is implemented in traditional ways that are brainstorming and checklist. These were due to lack of knowledge, the high cost of hiring experts and avoiding extra cost. Besides that, this study also intentions to analyse the risk categories in the construction industry as well as identify risk management process to resolve the construction issues. Hence, this paper presents issues engulfed by Bumiputera contractors which can partly be resolved by applying risk management practice in carrying out the construction activity. This may inspire the contractors to apply the risk management practice in ensuring the success of their construction project.

  7. Habituating pain: Questioning pain and physical strain as inextricable conditions in the construction industry

    Directory of Open Access Journals (Sweden)

    Jeppe Z.N. Ajslev

    2013-09-01

    Full Text Available In this article, we investigate the relations between discursive practices within the Danish construction industry and the perceived pain, physical deterioration, and strain affecting the construction workers. Of central importance is the widely accepted hegemonic discourse on physical strain and pain as unavoidable conditions in construction work. Based on 32 semi-structured interviews performed in eight case studies within four different construction professions, workers’ descriptions of physical strain and its relation to the organizational and social context are analyzed through concepts of subject positioning in discursive practice and a focus on power relations. The analysis shows that workers and employers reproduce certain types of traditional working class masculinities and search for high-pace productive working rhythms, which in combination with economic incentives common within the industry reproduce physical strain and the habituation of pain as unquestioned conditions in construction work. The understanding of this mutual reinforcement of the necessity of physically straining, painful, high-paced construction work provides fruitful perspectives on the overrepresentation of musculoskeletal deterioration within construction work and also sheds light on some of the difficulties in addressing and changing occupational health and safety practices in the construction industry.

    Full Text Available Performance measurement has received substantial attention from researchers and the construction industry over the past two decades. This study sought to assess UK practitioners’ awareness of the importance of the use of appropriate performance measures and its role in supporting the application of Lean Construction (LC concepts. To enable the study to achieve its objectives, a review of a range of measurements developed to evaluate project performance including those devoted to support LC efforts was conducted. Consequently a questionnaire survey was developed and sent to 198 professionals in the UK construction industry as well as a small sample of academics with an interest in LC. Results indicated that although practitioners recognise the importance of the selection of non-financial performance measures, it has not been properly and widely implemented. The study identified the most common techniques used by UK construction organisations for performance measurement, and ranked a number of non-financial key performance indicators as significant. Some professed to have embraced the Last Planner System methodology as a means for performance measurement and organisational learning, while further questioning suggested otherwise. It was also suggested that substance thinking amongst professionals could be a significant hidden barrier that militates against the successful implementation of LC.

    Full Text Available IBS precast concrete is construction system which is meant to improve the conventional construction process. However IBS precast concrete projects are suffering from serious problems such as cost overrun, delays and less quality of the end product. The absence of coordination is perceived as the reason for this issue. The purpose of this paper is to review the significance of coordination for IBS precast concrete in the construction industry. It if found that the fragmentation which occurs in the construction industry requires continuity of coordination due to the construction activities are intertwined in nature. Coordination is designated to assist stakeholders in completing and complementing each other with the paramount focus of achieving the objective. Proper coordination is required in delivering the desired construction product at the ideal time, cost and quality. As for the findings, the significance of coordination for IBS precast concrete can be seen through the precast concrete construction phases which consist of planning; design; manufacturing; transportation and installation/construction. These phases are meant to complement construction process with the purpose to reduce issues of fragmentation and enhance IBS precast concrete project delivery.

    The construction industry plays a significant role in contributing to the economy and development globally. During the process of construction, various hazards coupled with the unique nature of the industry contribute to high fatality rates. This review refers to previous published studies and related Malaysian legislation documents. Four main elements consisting of human, worksite, management and external elements which cause occupational accidents and illnesses were identified. External and management elements are the underlying causes contributing to occupational safety and health (OSH), while human and worksite elements are more apparent causes of occupational accidents and illnesses. An effective OSH management approach is required to contain all hazards at construction sites. An approach to OSH management constructed by elements of policy, process, personnel and incentive developed in previous work is explored. Changes to the sub-elements according to previous studies and the related Malaysian legislation are also covered in this review.

    The construction industry is characterized by a high number of fatal and nonfatal injuries and even higher prevalence of work-related diseases. The aim of this work is to analyze the results of a research project that has among its objectives the study of the prevalence of work-related diseases and the fitness to work in construction industry. In the period 2003-2011 were evaluated 2069 construction workers, from 218 companies (average age 37.9 years, mean seniority 21.1 years, 17.1 in the construction industry). The prevalence of work-related diseases was 14.06%, in the first place the noise-induced hearing loss, followed by musculoskeletal disorders and entrapment neuropathies. The 24.7% of fitness to work was influenced by the presence of limitations, the 0.6% of the population was not suitable for the specific task. The prevalence of work-related diseases in construction industry is high, with a peak among the elderly, but also significant occurrence among young people. It is important the percentage of the population with health problems that limit the fitness to work.

    Charles Y.J. Cheah

    2007-12-01

    Full Text Available The construction industry is one of the most hazardous industries due to the unique nature of its products and the processes involved. Recent occurrences of highly publicized construction site accidents in Singapore have highlighted the immediate needs for the local industry to address safety and attention at the industry level. The objective of this paper is to examine issues and critical factors affecting S&H standards in Singapore. Clearly, collective efforts should be pursued at the industry level as the country moves towards the ultimate safety management strategy of self-regulation. The findings also indicate that the challenge of making worksites safe should not be placed solely on the contractors but should be shared by all parties affecting the value chain of construction, including the developers, the consultants and the government. The factors identified through factor analysis may inform legislators and industry practitioners in terms of the sources of problems and help develop effective strategies for improvement. Some of the experiences mentioned in the paper could also be relevant to other countries facing similar circumstances.

Their range of applications is no longer limited to municipal wastewater but has expanded to the treatment of heavily polluted wastewaters such as agro-industrial effluents. This paper provides a comprehensive literature review of the application of constructed wetlands in treating a variety of agro-industrial wastewaters, and discusses pollutant surface loads and the role of constructed wetland type, prior-treatment stages and plant species in pollutant removal efficiency. Results indicate that constructed wetlands can tolerate high pollutant loads and toxic substances without losing their removal ability, thus these systems are very effective bio-reactors even in hostile environments. Additionally, the review outlines issues that could improve pollutant treatment efficiency and proposes design and operation suggestions such as suitable vegetation, porous media and constructed wetland plain view. Finally, a decision tree for designing constructed wetlands treating agro-industrial wastewaters provides an initial design tool for scientists and engineers.

    Full Text Available Background: In brick kiln and construction industry the exposure to carbon monoxide and silica dust is the most common occupational hazard to the workers in these industries. A study on occupational health hazards of working women in these two unorganized sectors was undertaken by Lokmanya Medical Research Centre. Objectives: To study the effect of work site environment on the health of the women working in brick kiln and construction industry. An attempt was also made to study the seasonal changes in the concentration of carbon monoxide and dust at the worksite. Material and Methods: A cross-sectional study was conducted among the working women (age 18-40 years at brick kilns and construction sites during summer and winter season. They were examined primarily to assess the effect of working environment on health. Gasteck Detector Pump of model 800 and air sampling instrument (SKC Air Check–52 were used to measure concentration of carbon monoxide and dust in the air respectively. Results: There were 66% of women who were in the age group of 18-40 years and most of them (94% were married. At brick kiln sites, average CO exposure was 62.8 ppm and 55.5 ppm and average dust exposure was 3 3 146.1 mg/m and 91.4 mg/m in summer and winter season respectively.At construction sites, average dust exposure was 41.5 ppm and 90.8 ppm in summer and winter. Conclusion: Both exposure to CO and dust were more in summer than in winter in brick kiln industry whereas in construction industry the exposure to dust was more in winter season. A high level of morbidity in the form of headache, bodyache, problems with vision, cough and breathlessness were observed in both industries. It is strongly recommended to take pollution control measures.

    Full Text Available The current dispute resolution procedures available in the Malaysian construction industry are mainly litigation and arbitration. In addition, the alternative dispute resolutions (ADR, namely mediation and adjudication, have also been introduced as the other methods for resolving disputes. The objective of this study is to examine the current practice of dispute resolution and ADR available in the Malaysian construction industry. The aim of this paper is two-fold: to report the current practice of dispute resolution and ADR, and identify the attributes of successful implementation of both mechanisms based on the perceptions of the Malaysian construction industry players. From the jurisprudence point of view, this study looks into the law as it is, in relation to the current practice of dispute resolution and ADR, by showing how those findings can be used to explain why improvement is needed to promote a successful and well received dispute resolution and ADR, and what lessons can be learnt, towards the formulation of a more viable methods for the Malaysian construction industry. NVivo software has been used to manage and organise the complete interview transcripts and facilitate the data analysis process for this study. Literature review reveals a continuous development of dispute resolution and ADR in the Malaysian construction industry, while, globally the industry has not only embraced ADR but also spearheaded the development of innovative forms of dispute avoidance mechanism. The findings of interviews show that locally, apart from litigation, the common types of ADR are arbitration, mediation and ad hoc mechanism. The findings also lead to the discovery of the following attributes: faster, less procedural, cost effective and enforceable; regulation and government's support; professionalism and ethic; training; and facility, that may promote a successful implementation of dispute resolution and ADR in Malaysia.

    2015-01-01

    The construction industry is one of the sectors with the highest accident rates and the most serious accidents. A multi-agent safety response approach allows a useful diagnostic tool in order to understand factors affecting risk and accidents. The special features of the construction sector can influence the relationships among safety responses along the model of safety influences. The purpose of this paper is to test a model explaining risk and work-related accidents in the construction industry as a result of the safety responses of the organization, the supervisors, the co-workers and the worker. 374 construction employees belonging to 64 small Spanish construction companies working for two main companies participated in the study. Safety responses were measured using a 45-item Likert-type questionnaire. The structure of the measure was analyzed using factor analysis and the model of effects was tested using a structural equation model. Factor analysis clearly identifies the multi-agent safety dimensions hypothesized. The proposed safety response model of work-related accidents, involving construction specific results, showed a good fit. The multi-agent safety response approach to safety climate is a useful framework for the assessment of organizational and behavioral risks in construction.

  12. Women in the Construction Industry in the U.K.: a Cultural Discord?

    Science.gov (United States)

    Bagilhole, Barbara M.; Dainty, Andrew R. J.; Neale, Richard H.

    The construction industry is the most male dominated of all industrial sectors in the United Kingdom. This article reports on a study that explored women's and men's experiences of working in the industry, focusing on how the cultural aspects of the workplace environment impinged upon women's career development. We interviewed more than 80 male and female construction professionals from large construction organizations, and compared their career accounts in order to establish the aspects of the workplace culture that had a gender-differentiated impact on progression. We found that construction organizations formed competitive "power" cultures where women's contributions were marginalized and their careers impeded through a combination of inflexible work practices and discriminatory behavior. These barriers to women's careers were maintained in small project teams by autonomous male operational managers. Their locus of control embraced recruitment, promotion, and staff development, which allowed them to sustain a workplace culture intolerant of nontraditional entrants. We conclude that this cultural environment is likely to remain problematic for women unless it can be changed in a way that values their contribution. This requires a radical shift in middle management attitudes, a departure from current organizational human resource management systems, and a wider acceptance of the need for cultural change within the industry.

    Construction industry players are known for their low acceptance on the changes. Hence, it is identified that the biggest challenge in the industry is changing the mindset. This paper highlights the importance of transformation in shaping for better future of the industry. Transformation favors innovation and progressive development in the industry and specifically in managing a project. Thus changes in mindset of players with an eye to the future and focus on what is coming are paramount in inculcating the transformation culture in construction eco-system. The key to the success of transformation is the collaborative and cooperative partnering which ensuring the performance of every stage of project delivery. The collaborative, cooperative and concerted effort of all parties involved in the project creates mutual understanding on mission and vision of project. Adopting healthy and harmonious project culture, implementing innovative procurement that emphasis on fair risk sharing should be a working culture. This cooperative partnership should be the future of the project undertaking in the construction industry.

Intervention components included universal General Awareness Training (GAT; general mental health with a focus on suicide prevention; gatekeeper training provided to construction worker volunteer ‘Connectors’; Suicide First Aid (ASIST training offered to key workers; outreach support provided by trained and supervised MIC staff; state-wide suicide prevention hotline; case management service; and postvention support provided in the event of a suicide. Findings from over 7,000 workers (April 2008 to November 2010 are reported, indicating strong construction industry support, with 67% building sites and employers approached agreeing to participate in MIC. GAT participants demonstrated significantly increased suicide prevention awareness compared with a comparison group. Connector training participants rated MIC as helpful and effective, felt prepared to intervene with a suicidal person, and knew where to seek help for a suicidal individual following the training. Workers engaged positively with the after-hours crisis support phone line and case management. MIC provided postvention support to 10 non-MIC sites and sites engaged with MIC, but not yet MIC-compliant. Current findings support the potential effectiveness and social validity of MIC for preventing suicide in construction workers.

    This paper presents the framework and protocol design for a construction industry risk management toolbox. The construction industry needs a comprehensive, systematic approach to assess and control occupational risks. These risks span several professional health and safety disciplines, emphasized by multiple international occupational research agenda projects including: falls, electrocution, noise, silica, welding fumes, and musculoskeletal disorders. Yet, the International Social Security Association says, "whereas progress has been made in safety and health, the construction industry is still a high risk sector." Small- and medium-sized enterprises (SMEs) employ about 80% of the world's construction workers. In recent years a strategy for qualitative occupational risk management, known as Control Banding (CB) has gained international attention as a simplified approach for reducing work-related risks. CB groups hazards into stratified risk 'bands', identifying commensurate controls to reduce the level of risk and promote worker health and safety. We review these qualitative solutions-based approaches and identify strengths and weaknesses toward designing a simplified CB 'toolbox' approach for use by SMEs in construction trades. This toolbox design proposal includes international input on multidisciplinary approaches for performing a qualitative risk assessment determining a risk 'band' for a given project. Risk bands are used to identify the appropriate level of training to oversee construction work, leading to commensurate and appropriate control methods to perform the work safely. The Construction Toolbox presents a review-generated format to harness multiple solutions-based national programs and publications for controlling construction-related risks with simplified approaches across the occupational safety, health and hygiene professions.

    Full Text Available The construction as a sector of the economy is one of the largest consumers of energy resources, and the building materials industry is today one of the most energy-intensive construction industry. At the enterprises of the building materials industry the different approaches and methods are used to solve resource and energy problems. Energy saving is considered not as an complex approach in the enterprise activity, but as activity for the implementation of specific energy-saving projects, which have limitations in time and in resources. The authors suggest to use a softwareoriented approach to solving the problems of resource and energy saving. For practical application of program-oriented approach we offer to use a structuring method of the decision-making, not previously used to solve problems of resource and energy saving.

    Full Text Available Constructed wetlands are characterized by specific conditions enabling simultaneous various physical and biochemical processes. This is the result of specific environment for the growth of microorganisms and hydrophytes (aquatic and semiaquatic plants which are capable of living in aerobic, anaerobic and facultative anaerobic conditions. Their interaction contributes to the intensification of oxidation and reduction responsible for the removal and retention of pollutants. These processes are supported by sorption, sedimentation and assimilation. Thanks to these advantages, treatment wetland systems have been used in communal management for over 50 years. In recent years, thanks to its advantages, low operational costs and high removal efficiency, there is growing interest in the use of constructed wetlands for the treatment or pre-treatment of various types of industrial wastewater. The study analyzes current use of these facilities for the treatment of industrial wastewater in the world. The conditions of use and efficiency of pollutants removal from readily and slowly biodegradable wastewater, with special emphasis on specific and characteristic pollutants of particular industries were presented. The use of subsurface horizontal flow beds for the treatment of industrial wastewater, among others from crude oil processing, paper production, food industry including wineries and distillery, olive oil production and coffee processing was described. In Poland constructed wetlands are used for the treatment of sewage and sludge from milk processing in pilot scale or for dewatering of sewage sludge produced in municipal wastewater treatment plant treating domestic sewage with approximately 40% share of wastewater from dairy and fish industry. In all cases, constructed wetlands provided an appropriate level of treatment and in addition the so-called ecosystem service.

    Development in Malaysia is booming which can be witnessed by the various construction projects that currently in progress, especially in the state of Johor which has the highest value of construction work completed for the third quarter of 2016. This necessarily requires skilled labours in a high number especially among the locals since it has been reported that Malaysia’s construction industry is having problems related to the shortage of local skilled labour. In addition, the local workers have been reported unable to fulfil the demand of construction market. Hence, it caused the contractor to import foreign workers to meet the needs and requirement of labour market in construction sector. This study aims of two objectives; to determine the criteria set by the construction company in recruiting local skilled labour and to study the strategies that can attract local skilled labour to join construction industry. Questionnaire has been distributed to G7 contractor in the state of Johor in order to achieve the objectives of this study. Collected data was then evaluated and tested for its reliability using the SPSS 20.0 software before it can be analysed in order to obtain the mean value, frequencies and percentage. The outcome of this study indicates that the prospective employer prefers to work with man and they require young, experienced, knowledgeable and skilled workers in doing the job. Most of the strategies that have been selected are mainly related to money namely salary increment, bonus, allowance and overtime payment, apart from upgrading labours welfare and providing a better accommodation. This study can be a guideline to both skills institution and contractor to improve on what they are lacking in order to encourage the local trained skills labour to join the industry.

    Malaysia considers the construction industry as one of the main contributors to its Gross Domestic Product (GDP). However, there are some unresolved issues arising from the ongoing and widespread adoption of the conventional method of construction such as the resultant fragmentation of the industry itself; delays in production and delivery time of unnecessary wastages and lack of sustainability practice. Malaysian Government has been continuously encouraging the industry to use, partly or if not wholly, the Industrialized Building System (IBS), which is considered to be an important part of sustainable construction initiative. IBS was introduced to Malaysia as the solution to issues related to dependencies of foreign workers, raising demand for affordable accommodations and improving image, quality and productivity of construction industry. However, the IBS adoption in Malaysia remains low. This paper presents the review of the current issues and barriers of IBS adoption in Malaysian construction industry.

    Full Text Available Environmental protection and economic growth are two indicators of sustainable global development. This study aims to investigate the performance of environmental protection and economic growth by measuring carbon productivity in the construction field. Carbon productivity is the amount of gross domestic product generated by the unit of carbon emissions. The log mean Divisia index method is used to investigate influential factors including carbon intensity, energy intensity and regional adjustment that impact on changes of carbon productivity. The study utilises a range of data from the Australian construction industry during 1995-2004 including energy consumption, industry value added and carbon dioxide equivalent consumption. The research indicates carbon productivity in the Australian construction industry has clearly increased. Energy intensity plays a significant positive role in promoting carbon productivity, whereas carbon intensity and regional adjustment have limited influence. Introducing advanced construction machinery and equipment is a feasible pathway to enhance carbon productivity. The research method is generic and can be used to measure other performance indicators and decomposing them into influential factors.

    Full Text Available The 3D printing technology is the engine key of the third industrial revolution, after introduction of the automation in the eighteenth century and the concept of mass production in early of twentieth century. 3D printing technology now offers the magic solution to balance both the benefits, and overcome the major associated problem with the previous concept which was the need of repetition. The 3D printing technology has two main critical success factors: the printing machine and the printing material (ink. This paper focusses on cementitious-based materials and the ability to utilize the technology in the construction industry. The research took a qualitative approach based on previous literature reviews as well as in-house research results carried out by the authors’ employer Research and Development Center. The paper summarizes the approach towards to an appropriate mix design which can achieve the requirement of the printing process, and overcome the current constraints which are hindering the wide application of 3D print in construction industry. The authors believe that the research topic and result will have great impact on pushing the construction industry forward towards achieving the UAE Government’s strategy and target to achieve twenty-five percent (25% of the buildings in Dubai by the year of 2030 relying on the 3D printing methodology. The research also concluded that even though the technology is adding a great value to the construction industry, it must be remembered that the technology is still in its infancy, and further research is required to achieve even higher strength printing materials that would be workable in multi-story buildings without the need of additional steel reinforcement.

    2017-01-01

    Construction workers globally face disproportionate threats to health and wellbeing, constituted by the nature of the work they perform. The workplace fatalities and lost-time injuries experienced by construction workers are significantly greater than in other forms of work. This paper draws on the culture-centered approach (CCA) to dialogically articulate meanings of workplace risks and injuries, voiced by Bangladeshi migrant construction workers in Singapore. The narratives voiced by the participants suggest an ecological approach to workplace injuries in the construction industries, attending to food insecurity, lack of sleep, transportation, etc. as contextual features of work that shape the risks experienced at work. Moreover, participant voices point to the barriers in communication, lack of understanding, and experiences of incivility as features of work that constitute the ways in which they experience injury risks. The overarching discourses of productivity and efficiency constitute a broader climate of threats to worker safety and health. PMID:28146056

    Mixed waste products are generated in the process of irrelevant industrial projects’ removal if conventional techniques of their demolition and dismantling are applied. In Russia the number of unused chemical industry facilities including structures with high rate of wear is growing. In removing industrial buildings and production shops it is used conventional techniques of demolition and dismantling in the process of which mixed waste products are generated. The presence of hazardous chemicals in these wastes makes difficulties for their use and leads to the increasing volume of unutilized residues. In the process of chemical industry facilities’ removal this fact takes on special significance as a high level of hazardous chemicals in the waste composition demands for the realization of unprofitable measures aimed at ensuring environmental and industrial safety. The proposed strategy of managing waste originated from the demolition and dismantling of chemical industry facilities is based on the methodology of industrial metabolism which allows identifying separate material flows of recycled, harmful and ballast components, performing separate collection of components during removal and taking necessary preventive measures. This strategy has been tested on the aniline synthesis plant being in the process of removal. As a result, a flow of 10 wt. %, subjected to decontamination, was isolated from the total volume of construction and demolition waste (C&D waste). The considered approach allowed using the resource potential of more than 80wt. % of waste and minimizing the disposed waste volume.

    The construction industry produces the highest number of occupational injuries in Spain (25.6%). Of these, 98.5% were minor injuries with 5 million workdays lost in 2000. This occurred even after the recent introduction of numerous health and occupational safety regulations. The objective of the present study was to identify the specific mechanisms of minor occupational injuries in the construction sector. In 2000, there were 235,853 minor occupational injuries in the construction industry. From these, injuries in general construction and civil engineering were selected (n = 155,044). These injuries affected both the total number of workers in the sector as well as bricklayers and unskilled construction workers. Insurance and financial activities (n = 2,019) were selected as a reference economic sector. Minor occupational injuries due to nontraumatic processes (heart attack, etc.) were taken as a control group (n = 167), assuming that the risk of nontraumatic processes was independent of economic activities. Odds ratios (OR) were adjusted by age, sex, years of work experience, type of employment and company size through nonconditional logistic regression models. The mechanisms with the highest risk of minor occupational lesions in construction workers as a group compared with employees in the financial sector were projection of fragments (OR = 33.0; 95% CI, 15.3-70.8) and being struck by objects (OR = 18.2; CI 95%, 9.7-34.1). These were also the most specific mechanisms of injury in the subgroup of bricklayers and unskilled construction workers. Activities aimed at preventing minor occupational injuries in the construction sector should be orientated towards these mechanisms, especially projection of fragments despite the low frequency of this mechanism compared with that of other mechanisms. Case-control design is a useful alternative approach for research into occupational injuries.

    Elton Mayo was born in Australia and spent most of his first 42 years living in that country. This article explores the Australian context in which he developed his views views of Australia compared with that of the United States during the time that Mayo developed his approach to psychology and the role of workers in industry. In addition, the social context in which Mayo established his career was shaped by significant political events in Australia. The construct of revery, which describes a specific state of consciousness, is central to Mayo's early theorizing and was developed by Mayo partly in reaction to political and industrial conflict occurring in Australia.

  2. LABOUR SUBCONTRACTING IN THE CONSTRUCTION INDUSTRIES OF DEVELOPING COUNTRIES: AN ASSESSMENT FROM TWO PERSPECTIVES

    Directory of Open Access Journals (Sweden)

    Jill Wells

    2006-06-01

    Full Text Available The practice of employing labour through subcontractors (often referred to as the ‘outsourcing’ of labour is both long established and widespread in the construction industries of developing countries. Recent studies show that it is also increasing in both developing and developed countries. An assessment of the advantages of the practice from the viewpoint of the contractors and of the labour force, suggests it is unlikely to disappear. The paper goes on to explore the implications for the development of the construction industry, as well as for the welfare of the workers and the achievement of broader development objectives. It is concluded that interventions may be needed to deal with some of the negative repercussions, but they have to accept and build on current labour practices.

    2008-01-01

    The aim of this work is to discuss about the role of the occupational physician in the prevention of the accidents in construction industry. Using the experience of 12 years of surveillance of workers in Bergamo province, the authors analyse the "human factors" which may influence the risk to have an accident, and the role of the physicians not only for the early diagnosis of work-related diseases, but also for the formulation of correct fitness to work, which consider accidents' prevention. Health conditions, psychological elements, fatigue and life style are some of the most important "human factors" which can amplify the accident phenomenon in construction industry. Our experience demonstrates that the occupational physicians can operate in preventive way on these factors, formulating correct fitness to work, giving their collaboration in the risk evaluation and management, suggesting runs of rehabilitation and recovery for the workers who need it, promoting information meetings related to the correct life habits.

    2017-05-01

    This study analyzed the Construction FACE Database (CFD), a quantitative database developed from reports of the Fatality Assessment and Control Evaluation (FACE) program conducted by the National Institute for Occupational Safety and Health (NIOSH). The CFD contains detailed data on 768 fatalities in the construction industry reported by NIOSH and individual states from 1982 through June 30, 2015. The results show that falls accounted for 42% (325) of the 768 fatalities included in the CFD. Personal fall arrest systems (PFAS) were not available to more than half of the fall decedents (54%); nearly one in four fall decedents (23%) had access to PFAS, but were not using it at the time of the fall. Lack of access to PFAS was particularly high among residential building contractors as well as roofing, siding, and sheet metal industry sectors (∼70%). Although the findings may not represent the entire construction industry today, they do provide strong evidence in favor of fall protection requirements by the Occupational Safety and Health Administration (OSHA). In addition to stronger enforcement, educating employers and workers about the importance and effectiveness of fall protection is crucial for compliance and fall prevention.

    High-temperature eutectic fixed points have proved to be convenient tools for temperature scale dissemination and thermometer calibrations/checks at temperatures above 1100°C. In order to investigate the feasibility of metal-carbon eutectic cells in industrial applications as a means for assessing the traceability of non-contact thermometers, a batch of cells was constructed at LNE-Cnam, NPL, and TUBITAK UME. Compared to the usual dimensions of high-temperature fixed point cells (45 mm in length × 24 mm in diameter), a new cell design was created to fit with industrial applications. TUBITAK UME constructed and characterized five ruthenium-carbon (Ru-C) eutectic cells of dimensions 24 mm in length × 24 mm in diameter. One of these cells has been selected and characterized at CEA premises. Ru-C eutectic cells have been evaluated in terms of short-term repeatability, reproducibility, furnace effect, sharp temperature ramps, and the effect of cell location. Measurements at TÜBİTAK UME have been performed with a transfer standard pyrometer calibrated at the copper point and a BB3500pg high-temperature blackbody furnace was used for construction and measurement. For the measurements at CEA, a Land Standard—HIMERT S1 radiation thermometer and a VITI induction furnace were used. In this article results of the measurements at TÜBİTAK UME and CEA will be presented. The possible use of these mini-eutectic cells as industrial temperature standards will be discussed.

  12. An Index to Measure Sustainability of a Business Project in the Construction Industry: Lithuanian Case

    Directory of Open Access Journals (Sweden)

    Nomeda Dobrovolskienė

    2015-12-01

    Full Text Available The continuous growth of the world population, resource scarcity and the threat of climate change pose numerous environmental and social problems to the world. Therefore, much hope is put in the concept of sustainability. Companies are increasingly coming under strong global pressure to incorporate sustainability considerations into their project decision-making process. Business projects in the construction industry are among the most important, as this sector is one of the largest sectors and of major importance for the national economy and therefore has a huge impact on the environment and society. Thus, we have to explore ways to integrate sustainability into the management of those projects. This paper presents a composite sustainability index of a project (CSIP which has been created following a review of existing literature and a pilot research study. A pilot research study was conducted in the Lithuanian construction industry between January 2015 and June 2015. Sustainability criteria were chosen and grouped on the basis of the analysis of the literature and different standards relating to sustainability applicable in the construction industry. A survey was used to select and rank the most important sustainability criteria. The index was constructed using multi-criteria decision-making methods. The results of the pilot study revealed that practitioners in the Lithuanian construction sector attach most importance to 15 sustainability criteria. A composite sustainability index of a project combining all these criteria may be useful in assessing the sustainability of a business project and making decisions regarding project portfolio selection and financial resource allocation. When addressing the issue of financial resource allocation in a project portfolio, the decision-maker could take into account not only the project’s return and risk, but also its sustainability. The understanding of this study should enable companies to execute

    It has been said that the construction industry must unleash its potential as a source of wealth creation and provide opportunity for the betterment of quality of life. In ensuring the quality of workmanship at construction sites, supervisory skills of site supervisors need to be enhanced. It stressed out that to match business growth and excellence overseas, we must recognize and act on the importance of continuously developing niche expertise and capabilities. Undoubtedly, the role of research in determining the specific leadership skills and the needed core capabilities cannot be over-emphasized. In ensuring the quality of workmanship at construction sites, leadership skills especially supervisory skill for site supervisors need to be enhanced. In this study, quantitative research design with survey questionnaire was used to collect the data and simple random sampling was employed in selecting 248 respondents involving team leaders in construction industry from whole of Malaysia. The data was analyzed using descriptive and inferential statistics; ANOVA in SPSS 21.0. Training and experience in leadership has been found to be significance to leadership capability of team leaders. The opinions from the respondents also indicated that they need the training of leadership and they had to enhance themselves to enable them to become better and more competitive leaders. The results of this assessment can pinpoint the areas needing improvement and therefore can be used as basis in designing and/or deciding development programmes. This study also found that generally the team leaders in construction industry needed more opportunities to expand their leadership capability to become the effective leaders in future.

    The agricultural industry in Malaysia has grown rapidly over the years. Palm oil clinker (POC) is a byproduct obtained from the palm oil industry. Its lightweight properties allows for its utilization as an aggregate, while in powder form as a filler material in concrete. POC specimens obtained throughout each state in Malaysia were investigated to evaluate the physical, chemical, and microstructure characteristics. Variations between each state were determined and their possible contributory factors were assessed. POC were incorporated as a replacement material for aggregates and their engineering characteristics were ascertained. Almost 7% of density was reduced with the introduction of POC as aggregates. A sustainability assessment was made through greenhouse gas emission (GHG) and cost factor analyses to determine the contribution of the addition of POC to the construction industry. Addition of POC helps to lower the GHG emission by 9.6% compared to control specimens. By channeling this waste into the construction industry, an efficient waste-management system can be promoted; thus, creating a cleaner environment. This study is also expected to offer some guides and directions for upcoming research works on the incorporation of POC.

    Industrialized Building System (IBS) is one of the approaches that had been introduced as an alternative to conventional building method where it becomes the new strategy of enhancing the sustainable construction in current industries while spearheading a huge advancement of benefits with green constructions into the existing industries. The IBS approach is actively promoted through several strategies and incentives as an alternative to conventional building methods. Extensive uptakes of modern Information Communication Technology (ICT) applications are able to support the different IBS processes for effective production. However, it is argued that ICT uptake at the organisational level is still in its infancy. This raises the importance to identify critical inhibitors which are inhibing the effective uptake of ICT in the IBS production management process. Critical inhibitors to ICT uptake were identified through questionnaire survey with the IBS industry stakeholders. The mean index and critical t-values are generated with the use of the quantitative tool, Statistical Package for Social Sciences (SPSS). The top ten priority ranked inhibitors reflect the Cost, People and Process elements to ICT uptake. High costs in acquiring the technologies and resistance to change were some main concerns from the findings.

    2011-06-01

    Full Text Available For over a decade, the public and the private sectors have carried out research aimed at attracting women engineers to the construction industry and retaining them. However, studies on women engineers working in other types of construction-related businesses apart from contractor companies such as consultancies, developers, etc., have not been many. This paper aims to examine the experiences of women engineers in non-traditional careers and the implications for their turnover. A literature search on women’s careers in construction was performed in conjunction with semi-structured interviews with a sampling of 141 individuals. Results from three viewpoints, viz those of professional men and women engineers in contractor companies, and women engineers in non-contractor companies, were found to differ in many respects, including their opinions about career advancement, career path and the difficulties involved. It was also found that women engineers in contractor companies were much more affected by problems such as sexual harassment, work-life conflicts and equal opportunity than women engineers in non-contractor companies. Turnover rates of women engineers and their reasons for leaving were examined. Women engineers, particularly those in contractor companies, had to confront more barriers in non-traditional careers than their male counterparts.  Nonetheless, working in non-contractor companies provides a viable alternative for women engineers who want to have successful careers in the Thai construction industry.

    2015-03-01

    Full Text Available Quality in a construction company is the key focus for competitiveness. The research described in this paper assesses the effectiveness of total quality management in construction industries. Thus, this study is aimed to investigate the four dimensions of total quality management which are fundamental for construction process. These for dimensions are quality management, quality control, quality assurance, and quality inspection. The regression analysis has been done to identify the effectiveness of these variables towards the quality in the company. The empirical result shows that quality management and assurance have the most effects towards quality as they are positively and significantly related to the quality. However the effect of the control and inspection are found not to be significant.

    This paper explores how three types of institutional pressure (i.e., coercive, mimetic and normative pressures) systematically impact on the safety climate of construction projects. These impacts are empirically tested by survey data collected from 186 questionnaires of construction companies operating in Shanghai, China. The results, obtained by partial least squares analysis, show that organizational management commitment to safety and employee involvement is positively related to all three institutional pressures, while the perception of responsibility for safety and health is significantly influenced by coercive and mimetic pressure. However, coercive and normative pressures have no significant effect on the applicability of safety rules and work practices, revealing the importance of external organizational pressures in improving project safety climate from a systematic view. The findings also provide insights into the use of institutional forces to facilitate the improvement of safety climate in the construction industry. Copyright © 2015 Elsevier Ltd.

    There are few data about safety in the construction industry in Palestine. The main aim of the study was to assess worker's experiences and perceptions of safety at construction sites in Hebron and Bethlehem governorates of the West Bank. A structured questionnaire was completed through direct interviews with 349 construction workers. Of the respondents, 34.6% had experienced work-related accidents, 13.0% and 65.6% indicated that their workplace did not have a first-aid kit or trained first-aid specialist respectively, 35.8% reported that their work sites did not have safety tools and 83.7% had not received safety training. Workers perceived that awareness and training were the most frequent factor affecting workers' safety, with the foreman position having the greatest impact on the workers' safety. Greater enforcement of the current Palestinian safety laws is needed.

    Full Text Available The construction industry operates primarily as a system of sub-contracting and purpose built alliances. There is a wide spread of stakeholders involved in conceiving a building project through typical stages such as design, finance, build,  manage, upgrade and, ultimately, replacement and a corresponding need for communication and cooperation. Specialists who can prevent bridges falling down or who build 20 storey buildings are seen as the hard-nosed, action people who have helped bring us into the modern era. However, there are intuitive activities and disciplines which help us to achieve the type of construction achievements that have been the hallmarks of the 19th, 20th and now the 21st centuries. Most of these so called soft disciplines are about how one helps people, often highly skilled, achieve those construction and engineering goals. The key components are consultation and communication. Communication strategies should be based on a thorough understanding of the ways that humans co-operate in joint undertakings, the key principles of social dynamics and learning theory plus the ways in which people deliver, accept and understand words and pictures. The disciplines of organisational and environmental psychology have become a basic fundamental of modern business activities from management and organisational strategy to marketing and customer relations and to the improvement of working, recreational and living environments. However it is rare for a mature industry such as construction to adopt or examine those disciplines for guidance about either strategies or operations. This is despite the fact that the construction industry is almost entirely based on the principle of sub-contracting, business and professional alliances, all of which require understanding of environmental psychology and social dynamics in order to build trust, reputation, teamwork and client satisfaction. There is therefore a major need for communications to be

    The kaleidoscopic applications of zeolite catalysts (zeo-catalysts) in petrochemical processes has been considered as one of the major accomplishments in recent decades. About twenty types of zeolite have been industrially applied so far, and their versatile porous architectures have contributed their most essential features to affect the catalytic efficiency. This review depicts the evolution of pore models in zeolite catalysts accompanied by the increase in industrial and environmental demands. The indispensable roles of modulating pore models are outlined for zeo-catalysts for the enhancement of their catalytic performances in various industrial processes. The zeolites and related industrial processes discussed range from the uni-modal micropore system of zeolite Y (12-ring micropore, 12-R) in fluid catalytic cracking (FCC), zeolite ZSM-5 (10-R) in xylene isomerization and SAPO-34 (8-R) in olefin production to the multi-modal micropore system of MCM-22 (10-R and 12-R pocket) in aromatic alkylation and the hierarchical pores in FCC and catalytic cracking of C4 olefins. The rational construction of pore models, especially hierarchical features, is highlighted with a careful classification from an industrial perspective accompanied by a detailed analysis of the theoretical mechanisms.

    Waste management is pressing very hard with alarming signals in construction industry. Concrete waste constituents major proportions of construction and demolition waste of 81% in Australia. To minimize concrete waste generated from construction activities, recycling concrete waste is one of the best methods to conserve the environment. This paper investigates concrete recycling implementation in construction. Japan is a leading country in recycling concrete waste, which has been implementing 98% recycling and using it for structural concrete applications. Hong Kong is developing concrete recycling programs for high-grade applications. Australia is making relatively slow progress in implementing concrete recycling in construction. Therefore, empirical studies in Australia, Hong Kong, and Japan were selected in this paper. A questionnaire survey and structured interviews were conducted. Power spectrum was used for analysis. It was found that "increasing overall business competitiveness and strategic business opportunities" was considered as the major benefit for concrete recycling from Hong Kong and Japanese respondents, while "rising concrete recycling awareness such as selecting suitable resources, techniques and training and compliance with regulations" was considered as the major benefit from Australian respondents. However, "lack of clients' support", "increase in management cost" and "increase in documentation workload, such as working documents, procedures and tools" were the major difficulties encountered from Australian, Hong Kong, and Japanese respondents, respectively. To improve the existing implementation, "inclusion of concrete recycling evaluation in tender appraisal" and "defining clear legal evaluation of concrete recycling" were major recommendations for Australian and Hong Kong, and Japanese respondents, respectively.

    Full Text Available Competitiveness of construction enterprises is the most important characteristic of the enterprise activity, which every business entity must constantly evaluate and undertake various kinds of measures to increase it. The development and implementation of these activities should be carried out with a clear understanding of the content of the enterprise competitiveness, and also by forming and analyzing the list of factors that affect the competitiveness. Subject: competitiveness of construction industry enterprises. Research objectives: reflecting the content of the notion of enterprise competitiveness and the main factors of its provision in the construction industry. Materials and methods: in the process of research, we applied the principles of ascent from abstract to specific, the unity of logical analysis, systematization, structuring and generalization. In the process of writing the paper, we used research and educational literature, articles in periodicals, Internet sources. Results: it is proposed to adhere to an integrated approach, according to which the competitiveness of an enterprise should be understood as the ability of an enterprise to conduct activities in the market, outrunning competitors, effectively using its own internal capabilities and taking into account environmental factors, paying attention to market conditions, features of regional development, characteristics of the industry, and at the same time, making sufficient profit that allows the enterprise to increase its potential. It is important to note that the factors of ensuring the competitiveness of the enterprise are mostly divided into external and internal ones, which, of course, is suitable for construction companies because they are open systems influenced by factors of the external and internal environment. The conducted analysis of the external factors allowed us to divide them into four groups: world-class factors, macro-level factors, meso-level factors and

    Full Text Available As the result of government’s initiative and future outlook in uprising the awareness towards the implementation of sustainable elements in construction industries, the Industrialized Building System (IBS is one of the approaches that had been introduced as an alternative to conventional building method and produce the new strategy of reducing the waste of materials in construction. The IBS approach is actively promoted through several strategies and incentives as an alternative to conventional building methods. Extensive uptakes of modern Information Communication Technology (ICT applications are able to support the different IBS processes for effective production. However, it is argued that ICT uptake at the organizational level needs to be regularly improved. Thus, this paper fulfills the need to identify the critical barriers to ICT employment and highlighting the ICT drivers in enhancing the IBS management process. Critical barriers and drivers to ICT uptake were identified through questionnaire survey with industry stakeholders and were analyzed using mean index and critical t-value with the use of SPSS software. The critical drivers are top management support and commitment and improving the availability of the technologies. The critical drivers which were identified are significant in ensuring the enhancement of ICT implementation. Hence, any system in place should avoid the highest ranked barriers or seek to alleviate their impact by focusing on the identified drivers in order to enhance implementation of ICT in IBS process management.

    The Jordanian construction industry plays a significant role and contributes immensely to the gross domestic product (GDP) of the economy. However, the Jordanian public work and housing ministry and most industry players including engineers and contractors have reported that most of the projects experience delays which lead time and cost overruns, and extra efforts. The main causes of delays identified by researchers include poor scheduling and planning, change orders, site conditions, weather, late deliveries, incompetent technical staff. To address these challenges, the implementation of building information modelling (BIM) is paramount. This paper presents BIM as a powerful tool for reducing delays in Jordan construction projects. The paper focuses on two main parts; the first part involves the identification of the major causes of delays, and the second part is to accurately outline the roles and responsibilities of BIM specialist in construction projects. Finally, the paper matches the roles and responsibilities of BIM specialist and the causes of delays, and how the delays are addressed through BIM specialist.

    2017-12-01

    To assess personal exposure to respirable dust and respirable crystalline silica (RCS) in New Zealand construction workers. In a pilot study, 39 personal samples were collected from a cross-section of workers engaged in a range of tasks performed on construction sites that were expected to entail exposure to respirable crystalline silica. Nine static samples were taken at locations adjacent to these tasks. Particle size-selective sampling heads were used to collect the respirable fraction of airborne particulates. Dust concentrations were determined gravimetrically, while crystalline silica was analysed using x-ray diffraction. Almost half of the personal crystalline silica samples exceeded the New Zealand Workplace Exposure Standard (NZ WES), while 56% exceeded the more stringent international recommendation (ACGIH TLV). The tasks associated with the highest RCS levels were concrete grinding and cutting. Two of four static samples collected close to (silica-containing) Linea board cutting exceeded the ACGIH TLV for RCS, indicating the potential for bystander exposure. A large proportion of workers performing common tasks in the construction industry may be exposed to levels of respirable dust and crystalline silica exceeding national standards and international recommendations. These results suggest that workers in this industry may be at risk of developing silica-related diseases, including silicosis, lung cancer, COPD and chronic renal disease. Action is required to improve dust control to reduce silica exposure and the associated health risks.

    2017-10-01

    Red mud is a waste originated in the processing of bauxite into aluminium, which properties of high alkalinity make it cumulatively stored, occupying increasing deforested areas. Annually, it is estimated that approximately 117 million tons of red mud are generated in the world, with no prospect of use, what represents an imminent risk of pollution prone to contamination. Nevertheless, environmental liabilities caused by red mud affect not only the environment, but also the companies responsible for the waste, which will be subject to highest fee payments. Although there are studies that prove the feasibility of using this solid waste in the constitution of ceramic materials, there are no large-scale applications. This study seeks to evaluate the possibilities of red mud application in construction industry, focusing into two main areas: cement production/ceramic material and road construction. Backgrounds from other researchers were taken into consideration and analysed according environmental, economic and technical feasibilities.

    2016-12-01

    The incorporation of niche construction theory (NCT) and epigenetics into an extended evolutionary synthesis (EES) increases the explanatory power of evolutionary analyses of human history. NCT allows identification of distinct social inheritance and cultural inheritance and can thereby account for how an existing-but-dynamic social system yields variable influences across individuals and also how these individuals' microlevel actions can feed back to alter the dynamic heterogeneously across time and space. An analysis of Chinese footbinding, as it was ending during the first half of the twentieth century and China was industrializing, illustrates the evolutionary dynamics of niche construction across inheritance tracks and explains regional heterogeneity as well as the persistence of a cultural belief that was socially inaccurate. Incorporating anthropological and sociological insights into an EES with NCT has the potential to proffer source laws for relationships between individual actions and macro-patterns in beliefs, structures, climate, and demography.

    The study relevance is determined by the increasing interest in reconstruction of city historical centers and located in the area of industrial buildings the functional profile of which needs to be changed. The problem of obtaining extra usable spaces in the historical centers of cities is solved by raising the number of storeys in the buildings which can be achieved by the construction of additional built-in inter-floor overlaps. The article is dedicated to the analysis of the recent years’ experience in reconstruction design involving this method in our country and abroad, in the Netherlands, in particular. The article presents the results of the analysis of the experience in reconstruction of the objects by constructing additional inter-floor overlaps and aims to define the optimum construction solution for built-in inter-floor overlapping and to develop non-existing solutions for wide application of this method in the reconstruction of a building with non-unified and unmodulated parameters. It was determined as expedient to apply a monolith reinforced concrete slab with the use of steel profiled flooring as a formwork and reinforcement and steel beams designed as “Built-in Beams” for the construction of built-in inter-floor overlaps in reconstruction. The article will be useful for specialists doing research in the sphere of reconstruction of the buildings and for the practical activity of design engineers.

    Full Text Available Although significant changes at the social, demographic, technological and workforce levelshave transformed the relationship between family and work, these changes have notbeen reflected in the employment practices of many construction companies. Many of thejob and organisational factors found to be negatively associated with family functioning arepertinent to construction professionals. Staff are expected to work long hours in demandingroles and this, combined with job insecurity and frequent relocation, means that familylife and individual well-being can be compromised. A growing body of research has foundthat the implementation of family-friendly work policies and practices can lead to greaterproductivity, lower attrition rates and higher morale in the workplace. In addition providinga work environment that is supportive of workers' family roles can help to alleviate workrelatedmental health problems.This paper outlines the changing demographic trends and societal attitudes that are makingindividuals and organisations question current work cultures and structures. Optionsfor making the construction industry a more family-friendly work environment are considered.All professionals, regardless of their age, gender and family responsibilities, canbenefit from these initiatives. The paper concludes by discussing the implications of theseissues for construction companies and future research work.

Taking into account the fact that economic efficiency is quite complex and multifaceted category, coupled with the economic laws and applies to all activities of the enterprise this figure is one of the essential characteristics of the processes occurring in industrial organizations. The lack of a generally accepted view among domestic and foreign economists regarding the essential part of the index of efficiency of activity of the industrial enterprise leads to the impossibility of its use for the management of processes. In the conditions of market economy, the task of economic evaluation res ults of the economic entity remains an important element of the research aspects of the company. Each new refinement of recorded knowledge acts as a stimulus for the development of fundamental knowledge categories. One of the Central in the system of economic categories, in our opinion, is indicated for the effective functioning of the enterprise." Precise formulation of the conceptual framework, criteria-based composition have important theoretical value to justify the subject of any research conducted in the conditions of modern economic development of the global space.

    Full Text Available Productivity is key to the survival and growth of any organisation, industry or nation. Some factors constrain the achievement of the set project objectives in the New Zealand building and construction industry and are responsible for the reported steady decline of productivity and performance. This study aims to identify the key constraints to on-site labour productivity and improvement measures. Using the descriptive survey method, views of some project managers, contractors and subcontractors in New Zealand were canvassed via pilot interviews and questionnaire surveys at the qualitative and quantity data gathering stages, respectively. Multi-attribute technique was used to analyse the quantitative data. Results showed that the key external constraints to on-site labour productivity comprise, in order of decreasing impact, statutory compliance, unforeseen events and wider external dynamics. The internal constraints, which contribute 67 percent of the onsite productivity issues, comprise reworks, level of skill and experience of the workforce, adequacy of method of construction, buildability issues, and inadequate supervision and coordination. . The factors underlying each broad category of external and internal constraints are reported. The relative levels of impact of the identified constraints are expected to guide the project team in addressing the constraints in a cost-effective manner.

    The increasing trend of research and innovation developments in the field of construction industry and their impacts on the national economy have raised much attention in the recent years. In this respect, through the relationship that exists between innovation and patent protection means that the education system of civil engineering has to gear itself to provide a sense of direction to facilitate future civil engineers to meet the challenges through innovation. The aim of this paper is to examine the educational experience and inclination of civil engineering students at Universiti Sains Malaysia in terms of their educational readiness to invent and innovate based on patents' exploration. Specifically, this paper presents research evidence using a quantitative method through questionnaire surveys in determining the dimension of patent information usage for innovation purposes, with attention to the hierarchy of each usage aspect and outcome measures reported. Results of this study revealed that majority of the participants have a "simplistic and superficial" ideas of patents identification as a source of innovation. Although a fair number of participants have relatively good knowledge of patents and innovation, lack of practical exposure and experience in construction industry are still a problem frequently encountered in the preparation to invent and innovate based on patents' exploration. It is recommended that the research model is tested using a greater number of research participants.

    Full Text Available Several types of researches have been carried out prior to the new millennium on the subject of bidding strategies in the construction industry. Today, organizations are faced with a very complex decision of bid/no-bid because it requires the assessment of large number of highly inter-related variables. The study aims at examining different types of Contractors’ Bidding Strategies (CBS with a view to determining their impact on bid success. In line with the aim, the study objectives include; evaluation of different types of CBS and; assessment of the success rate of contractors’ bid. The method of approach elicits information on the number of projects bided and successes recorded over a period of time. A total of one hundred and seventy-one useable responses were retrieved from questionnaire administration. Descriptive statistics, tables and percentages as well as mean item score (MIS were used for data analysis. The study showed that lowest bid, public relations and joint venture bidding strategies have great impact on contractors’ bid success especially on residential, educational and administrative projects in the Nigeria Construction Industry (NCI. Therefore, the study concluded that relationship exists between contractors’ bidding strategies and equivalent successes recorded over a period of time. It is important to also know that lowest bid strategy still remains the most effective bidding strategy for public works contracting in the NCI.

  16. Examination of Green Building Drivers in the South African Construction Industry: Economics versus Ecology

    2014-09-01

    Full Text Available There is a large body of literature on green buildings, but few studies have focused on the motivation behind the construction of green buildings globally, and in South Africa in particular. This paper investigates the key drivers of green building in the Western Cape Construction Industry of South Africa and examines whether these drivers have changed over time. A comprehensive literature review was undertaken to provide an overview of green building issues globally and in South Africa, followed by an empirical investigation into the drivers of green building in South Africa using a multi-case study approach. The findings reveal that the key drivers of green building include rising energy costs, the industry’s Green Star rating system, competitive advantages and legislation. The study also indicates that these key drivers have not changed significantly over time. Taken together, these results suggest that the increase in green building has little to do with ecological factors and more to do with economic factors—operational costs and stakeholder demands. The paper concludes that as long as the cost of energy continues to increase and there are recognised industry rating systems in place, the need for green buildings is likely to remain.

    In Italy, almost 18% of the immigrants work in the construction industry, the principal sector of occupation for such workers. In the province of Bergamo, during 2009-2010, 29.5% of workers in construction industry were immigrants. According to the protocol proposed by SIMLII, during 2009 910 workers underwent health surveillance, 708 were Italians, 202 immigrants. The prevalence of occupational diseases was related to years of service in construction industry and not to the origin of the workers. Nationality was not related with limitations in fitness for work. As regards lifestyles, particularly for smoking, alcohol drinking, drug consumption (declared and tested), immigrant workers showed a more virtuous behaviour than the Italians. According to the data issued by the local health authority, immigrant workers were most frequently involved in fatal accident at work than Italians. Therefore, there is a compelling call for action aimed at safety and prevention in workplaces, together with specific education for immigrants.

    Geologically ten percent of Sri Lanka is made up of Miocene limestone which covers northern and north-western coastal belt of the Island. It is used as a raw material for various industries but only cement and lime are being used for the construction industry. Except its chemical composition there is no available literature to study about other properties. Therefore the author carried out a series of laboratory tests to find out the mechanical properties of limestone in Sri Lanka. The objective of this paper is to make a note on the various properties of Miocene limestone and describe its suitability to use as an aggregate for the construction industry in Sri Lanka. Borehole samples (NX size) of limestone were obtained from various drilling sites in Northern Province of Sri Lanka and selected samples were prepared for different laboratory tests after visual observations. The tests were carried out according to ASTM Standards at the geotechnical and materials testing laboratories. The number of samples per each test was different. The range (and average result) for each property can be mentioned here as bulk density 2213-2643 (2452) kg/m3, water absorption 2.2-4.5 (1.91)%, porosity 1-15 (6.5)%, specific gravity 2.58-2.68(2.62), ultrasonic pulse velocity P wave 4480-6338 (5668) m/s and S wave 2688-3802 (3400) m/s, uniaxial compressive strength 11-92 (35)MPa, point load strength 1.2-7.1 (3.7)MPa, aggregate impact value, AIV 25-30 (28)%, LAAV 35-38 (36)%, and Brazilian tensile strength 2.1-4.4 (3.2)MPa. Poisson's ratio 0.12-0.68 (0.22) and modulus of elasticity 42-85 (62) GPa were obtained by using P and S ultrasonic wave velocity values. According to LAAV and AIV this limestone may be suitable as the base course material for road construction but may not be suitable for surface material of highways and rail road ballasts. Ultrasonic velocity waves indicate that limestone is highly compacted and solid. According to the compressive strength of solid limestone rock a few

    With the increase of the annual sand demand for the construction industry the excessive excavation of river sand is becoming a serious environmental problem in Sri Lanka. Therefore, it is necessary to explore the possibility for an alternative to stop or at least to minimize river sand mining activities. Dune sand is one of the available alternative materials to be considered instead of river sand in the country. Large quantities of sand dunes occur mainly along the NW and SE coastal belt which belong to very low rainfall Dry Zone coasts. The height of dune deposits, vary from 1m to about 30 meters above sea level. The objective of this paper is to indicate some studies and facts on the dune sand deposits of Sri Lanka. Laboratory studies were carried out for visual observations and physical properties at the initial stage and then a number of tests were carried out according to ASTM standards to obtain the compressive strength of concrete cylinders and mortar cubes mixing dune sand and river sand in different percentages keeping a constant water cement ratio. Next the water cement ratio was changed for constant dune sand and river sand proportion. Microscopic analysis shows that the dune sand consist of 95 % of quartz and 5 % of garnet, feldspar, illmenite and other heavy minerals with clay, fine dust, fine shell fragments and organic matters. Grains are sub-rounded to angular and tabular shapes. The grain sizes vary from fine to medium size of sand with silt. The degree of sorting and particle size observed with dune sands are more suited with the requirement of fine aggregates in the construction industry. The test result indicates that dune sand could be effectively used in construction work without sieving and it is ideal for wall plastering due to its'-uniformity. It could also be effectively used in concrete and in mortars mixing with river sand. The best mixing ratio is 75% dune sand and 25% river sand as the fine aggregate of concrete. For mortar the mixing

    This paper aims to develop a construction and operation cost model of wastewater treatment for the paper industry in China and explores the main factors that determine these costs. Previous models mainly involved factors relating to the treatment scale and efficiency of treatment facilities for deriving the cost function. We considered the factors more comprehensively by adding a regional variable to represent the economic development level, a corporate ownership factor to represent the plant characteristics, a subsector variable to capture pollutant characteristics, and a detailed-classification technology variable. We applied a unique data set from a national pollution source census for the model simulation. The major findings include the following: (1) Wastewater treatment costs in the paper industry are determined by scale, technology, degree of treatment, ownership, and regional factors; (2) Wastewater treatment costs show a large decreasing scale effect; (3) The current level of pollutant discharge fees is far lower than the marginal treatment costs for meeting the wastewater discharge standard. Key implications are as follows: (1) Cost characteristics and impact factors should be fully recognized when planning or making policies relating to wastewater treatment projects or technology development; (2) There is potential to reduce treatment costs by centralizing wastewater treatment via industrial parks; (3) Wastewater discharge fee rates should be increased; (4) Energy efficient technology should become the future focus of wastewater treatment.

    Sustainable development is forward-looking; it is a continuous mission for future developments of human society. A genuinely sustainable society is one that initiates developments in sustainable ways. The development of a genuinely sustainable society is supported by its citizens who think and act according to a recognized code of conduct - the sustainable culture. Similar to other forms of culture, sustainable culture of a society is not static, but changes over time. The changes found in a sustainable culture are reflections of the status of sustainability in a society and these changes should be measured from time to time. The resulting measurement gives very important information for decision-makers, in the government and in the private sector, to examine the magnitude of changes that have taken place in a given period of time. The results will also enable them to review and adjust policies in order to better accommodate changes according to the trends of society. This paper provides a method - the T-model, to investigate and measure the extent of change of sustainable culture through two extensive surveys among participants of the construction industry of Hong Kong. The change in sustainable culture is reflected by the change in attitude and practice among construction participants, this can be found in their performance in project development, design and construction operations. The data of these changes are collected and converted to numerical scores. The T-model synthesized these scores and revealed the change of sustainable culture within the specific study time frame.

    The construction industry has hit a plateau in terms of safety performance. Safety climate is regarded as a leading indicator of safety performance; however, relatively little safety climate research has been done in the Canadian construction industry. Safety climate may be geographically sensitive, thus it is necessary to examine how the construct of safety climate is defined and used to improve safety performance in different regions. On the other hand, more and more attention has been paid to job related stress in the construction industry. Previous research proposed that individual resilience may be associated with a better safety performance and may help employees manage stress. Unfortunately, few empirical research studies have examined this hypothesis. This paper aims to examine the role of safety climate and individual resilience in safety performance and job stress in the Canadian construction industry. The research was based on 837 surveys collected in Ontario between June 2015 and June 2016. Structural equation modeling (SEM) techniques were used to explore the impact of individual resilience and safety climate on physical safety outcomes and on psychological stress among construction workers. The results show that safety climate not only affected construction workers' safety performance but also indirectly affected their psychological stress. In addition, it was found that individual resilience had a direct negative impact on psychological stress but had no impact on physical safety outcomes. These findings highlight the roles of both organizational and individual factors in individual safety performance and in psychological well-being. Construction organizations need to not only monitor employees' safety performance, but also to assess their employees' psychological well-being. Promoting a positive safety climate together with developing training programs focusing on improving employees' psychological health - especially post-trauma psychological

    Full Text Available A study measuring the performance of Guyana’s construction industry using a set of project performance benchmarking metrics was recently completed. The underlying premise of the study was that the aggregated performance of construction projects provides a realistic assessment of the performance of the construction industry, on the basis that construction projects are the mechanism through which the construction industry creates its tangible products. The fact that an influential government agency acted as owner of the study was critical to the data collection phase. The best approach for collecting project performance data in Guyana involves the utilisation of a researcher or team of researchers mining electronic and hard copy project documents. This study analysed approximately 270 construction projects to obtain an indication of the performance of guyana’s construction industry. It was found that sea defence projects performed the worst, whereas health facility projects performed the best. The main implication of this is that sea defence projects are likely to be the least efficient and, given their critical nature, there is an argument for urgent performance improvement interventions.

    Full Text Available The Romanian economic spectrum considered on a slightly increasing trend in the general aspects of the national economy, feels increasingly the need for a development in the cost management issue. One of the modern methods of cost calculation that can fill this gap in the Romanian business practice in management accounting is the target costing method. The overall objective of this case study is to demonstrate the applicability and usefulness of this method in the cost controlling activity, widely used in the field of managerial accounting practice in the developed economies. The financial accounting and the managerial accounting converge in terms of ultimate interest for the company, i.e. value creation and performance increase in a sustainable way. After performing the case study with real financial data, we conclude that the target costing method is applicable and particularly useful in the construction industry and the results may provide support for decision-makers.

    At least 60,000 fatal accidents at work occur on building sites all over the world each year, which means that on average, every 10 minutes an employee dies during the execution of work. In 2015 on Polish building sites, 5,776 accidents at work happened, of which 69 resulted in the death of an employee. Accidents are an enormous social and economic burden for companies, communities and countries. The vast majority of accidents at work can be prevented by appropriate and effective preventive measures. Therefore, the Computer Knowledge Database (CKD) was formulated for this purpose and it enables data and information on accidents at work in the construction industry to be collected and processed in order to obtain necessary knowledge. This gained knowledge will be the basis to form conclusions of a preventive nature

    Full Text Available The Social Network Analysis (SNA has been adopted in the UK construction management research and generated meaningful insights in analysing project management organisations from network perspectives. As an effective tool, social network analysis has been used to analyse information and knowledge flow between construction project teams which is considered as foundation for collaborative working and subsequently improving overall performance. Social network analysis is based on an assumption of the importance of relationships among interacting units. The social network perspective encompasses theories, models and applications that are expressed in terms of relational concepts or processes. Many believe, moreover, that the success or failure of organisations often depends on the patterning of their internal structure. This paper reviewed existing literatures on SNA applications in construction industry from three leading construction management journals.  From the review, the research proposed some advance in the application of SNA in the construction industry.

Resultados bem documentados apontaram que a exposição prolongada a poluentes químicos, proveniente do consumo, produção, armazenamento etc., pode causar danos à saúde do trabalhador. Recentemente, estudos direcionados a ambientes não industriais mostraram correlações surpreendentes entre a qualidade do ar e os efeitos causados à saúde. O sistema de ventilação artificial tem sido a principal causa de reclamações e de um alto índice de absenteísmo. Os sintomas relacionados com a qualidade do ar em ambientes não industriais são reconhecidos pela Organização Mundial da Saúde que os identifica como "Síndrome dos Edifícios Doentes". No Brasil, há poucos estudos relacionando qualidade do ar em ambientes fechados e saúde. O presente trabalho pretende mapear as pesquisas já realizadas no País, visando, com isso, incentivar novos estudos nessa área, em virtude de sua importância para a saúde da população.Air quality in industrial environments has been studied since the second half of the 20th century. Well-documented results show that exposure to chemical pollutants through their consumption, production, and storage can damage workers' health. New research focusing on non-industrial environments has shown unexpected correlations between air quality and health effects. Artificial ventilation systems have been related to health-related complaints and a high rate of absenteeism. Symptoms related to air quality in non-industrial environments are recognized by the World Health Organization and encompassed under the so-called sick building syndrome (SBS. In Brazil there are few studies comparing indoor air quality and health. The present study is intended to map the studies already conducted in Brazil in order to encourage further research in this area, due to its importance for public health.

    There are more than a hundred textile industries in Turkey that discharge large quantities of dye-rich wastewater, resulting in water pollution. Such effluents must be treated to meet discharge limits imposed by the Water Framework Directive in Turkey. Industrial treatment facilities must be required to monitor operations, keep them cost-effective, prevent operational faults, discharge-limit infringements, and water pollution. This paper proposes the treatment of actual textile wastewater by vertical flow constructed wetland (VFCW) systems operation and monitoring effluent wastewater quality using fuzzy logic with a graphical user interface. The treatment performance of VFCW is investigated in terms of chemical oxygen demand and ammonium nitrogen (NH4-N) content, color, and pH parameters during a 75-day period of operation. A computer program was developed with a fuzzy logic system (a decision- making tool) to graphically present (via a status analysis chart) the quality of treated textile effluent in relation to the Turkish Water Pollution Control Regulation. Fuzzy logic is used in the evaluation of data obtained from the VFCW systems and for notification of critical states exceeding the discharge limits. This creates a warning chart that reports any errors encountered in a reactor during the collection of any sample to the concerned party.

    Laboratory investigations were carried out to establish the potential utilisation of brick dust (BD) in construction. The dust is a waste material from the cutting of fired clay bricks. Currently, the disposal of the dust is a problem to the brick fabrication company, and hence an environmental pollution concern. The dust was stabilised either used on its own or in combination with Pulverised Fuel Ash (PFA), a by-product material from coal combustion. The traditional stabilisers of lime and/or Portland Cement (PC) were used as controls. The main aim was to use a sustainable stabiliser material, where these stabilisers were partially replaced with Ground Granulated Blastfurnace Slag (GGBS), a by-product material from steel manufacture. Compacted cylinder test specimens were made at typical stabiliser contents and moist cured for up to 56 days prior to testing for compressive and California Bearing Ratio (CBR) strength tests, and to linear expansion during moist curing and subsequent soaking in water. The results obtained showed that partial substitution of the dust with PFA resulted in stronger material compared to using it on its own. The blended stabilisers achieved better performance. These results suggest technological, economic as well as environmental advantages of using the brick dust and similar industrial by-products to achieve sustainable infrastructure development with near zero industrial waste.

  18. Developing a Mobile Phone Based GUI for Users in the Construction Industry: A Case Study

    Science.gov (United States)

    Yammiyavar, Pradeep; Kate, Prasanna

    This paper reports work done in conceptualizing, developing and testing of a mobile phone based graphical user interface (GUI) package targeted at users from the construction industry. System analysis and information design principles were adopted during the development processes. Starting from user requirements based on field studies the development of graphic icons and their testing has been outlined. In addition to integrating individual icons into a GUI, coding and loading the application on a mobile phone has been done to enable testing of the GUI prototype. Users from the construction trade (sample size = 29), randomly selected, were asked to evaluate the designed icons in terms of their acceptance, adaptability and learnability aspects. It was found that learnability of the new GUI was more dependent on age and education level of the user rather than on the length of prior experience they had with mobile phones in general. The length of experience of using mobiles may not be an indicator of learnability in new applications for such user segments due to rapid rise in 'digital literacy' levels amongst semi literate users.

    Full Text Available The UK construction industry has long been criticised for engendering adversarial relationships among project participants. The nature of interrelationships ultimately determines overall project performance%2C in terms of finished product%2C and levels of performance and satisfaction for the participants. To investigate these interrelationships%2C the performance and satisfaction of each individual participant must be considered. Better understanding of the interrelationships should help reduce adversarialsm and improve the performance and satisfaction of each participant. The possible interrelationships that may exist are discussed based on %91soft knowledge%92 approaches%2C i.e. psychology%2C organisational behaviour and sociology. It is concluded that the performance of each participant is interdependent and essential towards project performance. Two levels of satisfaction%2C which determine the quality of working relationships between participants%2C are postulated. The first level of satisfaction %28i.e. satisfaction on achieving organisational objectives%29 is%2C to some extent%2C dependent on the second level of satisfaction %28i.e. satisfaction on the performance of the other participants%29. Therefore%2C within the construction project coalition%2C each participant has to be satisfied with the performance of the other participants if harmonious working relationships are to be sustained. Based on these%2C a conceptual model for optimising the relationships between main participants of the project coalition is presented.

    Full Text Available The study adopts a data reduction technique to examine the presence of any complex structure among a set of project management competency variables. A structured survey questionnaire was administered to 100 project managers to elicit relevant data, and this achieved a relatively high response rate of 54%. After satisfying all the necessary tests of reliability of the survey instrument, sample size adequacy and population matrix, the data was subjected to principal component analysis, resulting in the identification of six new thematic project management competency areas ; and were explained in terms of human resource management and project control; construction innovation and communication; project financial resources management; project risk and quality management; business ethics and; physical resources and procurement management. These knowledge areas now form the basis for lateral project management training requirements in the context of the Ghanaian construction industry. Key contribution of the paper is manifested in the use of the principal component analysis, which has rigorously provided understanding into the complex structure and the relationship between the various knowledge areas. The originality and value of the paper is embedded in the use of contextual-task conceptual knowledge to expound the six uncorrelated empirical utility of the project management competencies.

    Full Text Available This study compares the level of project planning on public andprivate sectors projects and its impact on performance. Thepurpose is to create awareness of the level and effectivenessof the planning done by public and private clients in the deliveryof construction projects. A questionnaire survey administeredto a sample of 130 client representatives selected by stratifi edrandom sampling from the population of public and private clientsin the Nigerian construction industry is used and analysed usingdescriptive statistics, the t-test and Spearman correlation test. Theresults show that the level of preconstruction planning on privatesector projects is higher than that of public sector projects whilethe level of contract planning done by the latter is higher thanthat of the former. Furthermore, the performance of private sectorprojects is higher than that of public sector projects in many of theparameters used. However, the level of preparation of life-cyclecharts that concern project delivery time in both public and privatesectors projects is low and the level of project planning in the twocategories of projects has a limited impact on project performance.The understanding of how public and private sectors projectsperform in planning and its impact are expected to assist publicand private clients to know the challenges ahead of them in theireffort to improve the planning and performance of their projects.

    Full Text Available While evaluating the built environment, predominant agreement on what aspects constitute an achievement or failure in architecture is changing in the course of time. The subject of the research is value set agreements in regional comprehension, followed by the generic tree of award in architecture and construction industries of Latvia. Recently, besides the original task of promoting quality, the judgment typology can be considered a significant evidence of what the contemporary questions, problems and challenges consist of in the regional architecture. Based on the method of analytic comparison, this research paper lists regional awards as established public forms of judgment, reflected in professional editions and mass media during the last two decades. By sorting them by responsible initiatives, aim formulations, establishment data, criterion and target audience, the paper focuses on the general examination of affiliation segments and quantitative and qualitative indicators in the awards assigned since 1990. Conclusions include the data on widespread generalizations in the terms of criteria, segmentation and fragmentation, reputation of subjectivity, commercialization and expansive development in awarding, and at the same time raise the lack of constructive criticism culture in Latvia.

    Full Text Available Impotent planning system in house providing process is the result of inadequate housing management system in theoretical, empirical, and operational fields. In addition, Mass Construction industry in Iran confronts with other problems such as instability in raw material prices, unsteadiness in production and investment laws and regulations, frailty of transportation infrastructure, international sanctions and etc. Furthermore, customers’ needs, lower costs, and greater customizations lead mass producing to search for new solutions and novel producing system. Agility is offered as a strategy to enable Mass Construction associations to be maintained in the competition of constantly changing market in Iran. In such a market, previous approaches lose their capabilities in supply chain. Thus to achieve agility by Mass Construction association is the chief aim of this study. This study is descriptive-analytic and can be identified as developmental –functional considering its target. After surveying previous research literature and using experts’ opinions, we investigated final agile sub criteria of supply chain and then we used interpretive- structural modeling approach to determine the relation among sub criteria and to offer an agile supply chain model. Surveying research literature and experts’ opinions lead us to identify 8 criteria (society, government, financial, information technology, market, partnership, quality and technology and also 22 sub criteria for supply chain’s agility. Then the results were analyzed through interpretive-structural approach and relation of criteria and sub criteria and their consequence were achieved. These relations showed that government and infrastructure investment, culture, regulations and responses to social and environmental issues are the basis of agility in mass housing productions’ supply chain. This model helps supply chain managers to have strategic planning to enhance agility in supply chain

    2014-09-01

    Different industries manage the threats presented by HIV and AIDS in different ways. The construction industry is particularly vulnerable to the pandemic because of its large unskilled labour force, high labour turnover and the migratory nature of the workforce. The study reported on in this paper, the first of its kind in the South African construction industry, aimed to identify the important drivers needed for the effective management of HIV and AIDS and to understand their impact on the construction industry. The aim was achieved in two stages. The first stage involved an extensive literature review to determine the factors that drive corporate response in the management of HIV and AIDS in the South African construction sector. Six drivers, namely legal requirements, social pressures, business costs, voluntary regulation, visibility of the disease, and individuals within companies with a total of 87 items were identified. An iterative Delphi technique with a panel of experts was used to validate the factors identified in the literature review and formed the second stage of this research. The Delphi method was used as it provided a systematic approach to achieve consensus on the six drivers for effective management of HIV and AIDS management in the construction industry. An expert panel responded to three iterations of questionnaires to achieve consensus. The experts reached consensus on 56 items categorised under the 6 drivers. This study found that the legal driver was considered most important but only second in terms of impact. The second most important driver was the visibility of the disease and was regarded as the driver with the highest impact. Internal agents ranked third in terms of importance and impact. This study can be used for further research to assist the construction industry in helping fight HIV and AIDS.

  6. An Ethical (Descriptive) Framework for Judgment of Actions and Decisions in the Construction Industry and Engineering-Part I.

    2017-03-20

    The construction industry is usually characterized as a fragmented system of multiple-organizational entities in which members from different technical backgrounds and moral values join together to develop a particular business or project. The greatest challenge in the construction process for the achievement of a successful practice is the development of an outstanding reputation, which is built on identifying and applying an ethical framework. This framework should reflect a common ethical ground for myriad people involved in this process to survive and compete ethically in today's turbulent construction market. This study establishes a framework for ethical judgment of behavior and actions conducted in the construction process. The framework was primarily developed based on the essential attributes of business management identified in the literature review and subsequently incorporates additional attributes identified to prevent breaches in the construction industry and common ethical values related to professional engineering. The proposed judgment framework is based primarily on the ethical dimension of professional responsibility. The Ethical Judgment Framework consists of descriptive approaches involving technical, professional, administrative, and miscellaneous terms. The framework provides the basis for judging actions as either ethical or unethical. Furthermore, the framework can be implemented as a form of preventive ethics, which would help avoid ethical dilemmas and moral allegations. The framework can be considered a decision-making model to guide actions and improve the ethical reasoning process that would help individuals think through possible implications and consequences of ethical dilemmas in the construction industry.

    Full Text Available Microfinance has been one of the fastest growing “industries” of the new millennium, with the sector now containing over 10,000 microfinance institutions (MFIs worth an estimated USD with over $60 billion in assets (Microfinance Information Exchange 2011. This expansion has stimulated interest from both scholars and the mainstream media. There is a growing volume of academic research which broadly centres on two approaches: an “institutionalist perspective” that highlights microfinance as an innovation in applying market solutions to social problems; and the other approach, often described as welfarist, that questions the capacity of an increasingly commericalised sector to realize a mission of poverty reduction. But do these themes and concerns permeate academic boundaries? Specifically, does media coverage in key donor and recipient countries confirm or challenge or even engage with these debates? To date much of this academic literature has overlooked how “microfinance” has been socially constructed in the public sphere through the mass media. Through its interpretation of events, the media can influence the way an issue is discussed and evaluated and in this way influence individual perceptions (Gamson 1988. In this article we present an analysis of recent media coverage of microfinance in one key donor country, the United States and one major recipient country, India. By conducting a media content analysis of 100 newspaper articles (sorted by level of relevance that appeared in the top 10 highest circulating English language newspapers in India and the US over a 12 month period January-December 2008 we discuss how media coverage in these two countries differed in significant ways. The Indian media sample tended to focus on operational issues and report on specific business activity within the microfinance industry, in general treating it as a ‘regular’ part of the financial and banking system.

    The rapid economic development has increased the demand for construction of infrastructure and facilities globally. Sustainable development and globalization are the new ‘Zeitgeist’ of the 21st century. In order to implement these projects successfully and to meet the functional aim of the projects within their lifetime, an efficient project management practice is needed. The aim of this study is to identify the critical success factors (CSFs) and the extent of use of project management practice which affects project success, especially during the implementation stage. Data were obtained from self-administered questionnaires with 232 respondents. A mixed method of data collection was adopted using semi-structured interview and questionnaire approach. The result of the analysis of data obtained showed that new and emerging criteria such as customer satisfaction, competency of the project team, and performance of subcontractors/suppliers are becoming measures of success in addition to the classic iron triangle’s view of time, cost and quality. An insight on the extent of use of different project management practice in the industry was also achieved from the study.

    Full Text Available The aim of every client at the beginning of any project is to have at the end of the day a quality structure delivered on time and within budget. However, researches have shown that in most cases this aim is not met. The aim of the study that formed the basis for this paper was to identify and assess procurement methods in use in the Nigerian construction industry and identify the factors that affect the choice of the variants under the traditional and the non-conventional procurement methods. Data were collected using well-structured questionnaires administered to professionals in Lagos metropolis. Data collected were analyzed using descriptive and inferential statistics. The study reveals that the variants of traditional method of contract procurement are the most adopted in project execution in Nigeria. In making choice of procurement method, the study reveals that project completion at estimated time ranks as the highest factor considered for traditional method, while quality assurance ranks highest with non-conventional method.

    Currently, the vast majority of organic construction, demolition and industrial (C, D and I) wastes in Sweden are sent to incineration plants as a (large sized) refuse derived fuel (RDF) for rather inefficient (15-35%) co-heat and power production. The nonmetallic inorganic fractions of these wastes are often deposited in landfills as filler. With recent economic incentives and rising tipping costs commercial research into the use of non-conventional processing techniques for the production of alternative products has become of greater interest. This study, a greatly abridged version of the author's recent thesis research performed in conjunction with the Swedish C, D and I handling partnership EDAB, attempts to give a glimpse of some of the more promising processes for these under used resources. In its compaction this paper is more of a literature review of these processes, rather than a specific case study and market analysis. For the respective waste streams a variety of thermal, mechanical, and biological processes are proving themselves to be more efficient, more profitable, and to have fewer negative environmental effects than conventional alternatives. Although some risks and implementation difficulties are still associated with these emerging technologies; greater resource utilization, improved product mobility, and potentially stronger economic performance will prove strong drivers for companies possessing compatible sets of characteristics to forge previously unconventional paths

    2017-12-01

    The construction industry is typically characterized as a fragmented, multi-organizational setting in which members from different technical backgrounds and moral values join together to develop a particular business or project. The most challenging obstacle in the construction process is to achieve a successful practice and to identify and apply an ethical framework to manage the behavior of involved specialists and contractors and to ensure the quality of all completed construction activities. The framework should reflect a common moral ground for myriad people involved in this process to survive and compete ethically in today's turbulent construction market. This study establishes a framework for moral judgment of behavior and actions conducted in the construction process. The moral framework provides the basis of judging actions as "moral" or "immoral" based on three levels of moral accountability: personal, professional, and social. The social aspect of the proposed framework is developed primarily from the essential attributes of normative business decision-making models identified in the literature review and subsequently incorporates additional attributes related to professional and personal moral values. The normative decision-making models reviewed are based primarily on social attributes as related to moral theories (e.g., utilitarianism, duty, rights, virtue, etc.). The professional and moral attributes are established by identifying a set of common moral values recognized by professionals in the construction industry and required to prevent common construction breaches. The moral framework presented here is the complementary part of the ethical framework developed in Part I of this article and is based primarily on the personal behavior or the moral aspect of professional responsibility. The framework can be implemented as a form of preventive personal ethics, which would help avoid ethical dilemmas and moral implications in the first place

    Construction waste management (CWM) is the practice of minimizing and diverting construction waste, demolition debris, and land-clearing debris from disposal and redirecting recyclable resources back into the construction process. Best practice model means best choice from the collection of other practices that was built for purpose of construction waste management. The practice model can help the contractors in minimizing waste before the construction activities will be started. The importance of minimizing wastage will have direct impact on time, cost and quality of a construction project. This paper is focusing on the preliminary study to determine the factors of waste generation in the construction sites and identify the effectiveness of existing construction waste management practice conducted in Malaysia. The paper will also include the preliminary works of planned research location, data collection method, and analysis to be done by using the Analytical Hierarchy Process (AHP) to help in developing suitable waste management best practice model that can be used in the country.

On the other hand, a large number of human resources are working in this whish shows they necessity for paying special attention to these workers. Therefore, risk assessment of the safety in the construction industry is an effective step in this regard. In this study, a method for ranking safety risks in conditions of low number of samples and uncertainty is presented, using gray multi-criterion decision-making. .Material and Method: In this study, we first identified the factors affecting the occurrence of hazards in the construction industry. Then, appropriate for ranking the risks were determined and the problem was defined as a multi-criterion decision-making. In order to weight the criteria and to evaluate alternatives based on each criterion, gray numbers were used. In the last stage, the problem was solved using the gray possibility degree. .Results: The results show that the method of gray multi-criterion decision-making is an effective method for ranking risks in situations of low samples compared with other methods of MCDM. .Conclusion: The proposed method is preferred to fuzzy methods and statistics in uncertain and low sample size, due to simple calculations and no need to define the membership function.

  1. Use of engineered nanomaterials in the construction industry with specific emphasis on paints and their flows in construction and demolition waste in Switzerland.

    One sector where the use of engineered nanomaterials (ENMs) is supposed to offer novel or improved functionalities is the construction industry. During the renovation or demolition of buildings, ENMs contained in former construction materials will enter recycling systems or become construction waste. Currently, information about ENM flows in these processes is insufficient. The potential for the release of ENMs from this waste into the environment is unknown, as are the environmental impacts. To evaluate whether there is currently any nano-relevant construction and demolition waste (C&DW) originating from buildings, we evaluated the sources and flows of ENMs in C&DW and identified their potential exposure pathways. A survey of business representatives of Swiss companies in this sector found that ENMs are mainly used in paints and cement. The most frequently used ENMs in the Swiss housing construction industry are nano-TiO2, nano-SiO2, nano-ZnO, and nano-Ag. Using a bottom-up, semi-quantitative approach, we estimated the flows of ENMs contained in paints along the product's life cycle from buildings to recycling and landfill. The flows of ENMs are determined by their associated flows of building materials. We estimated an annual amount of ENMs used in paints of 14t of TiO2, 12t of SiO2, 5t of ZnO, and 0.2t of Ag. The majority of ENMs contained in paints in Switzerland enter recycling systems (23t/y), a smaller amount is disposed directly in landfills (7t/y), and a tiny fraction of ENM waste is incinerated (0.01t/y). Our results allow a qualitative determination of the potential release of ENMs into technical or environmental compartments, with the highest potential release expected during recycling.

    Full Text Available Industrialised Building System (IBS is the common term used to represent the prefabrication concept in Malaysia. Based on previous research being done locally and internationally, it is certain that using IBS offers huge benefits in terms of cost, time, productivity and quality. The Malaysian construction industry has been urged to use innovative construction techniques. It is being highlighted under the present Construction Industry Transformation Programme 2016 - 2020 (CITP. These initiatives illustrate the Malaysia government’s commitment in addressing the IBS agenda. Although some efforts have been taken to enhance the IBS adoption in Malaysia, various contract issues have emerged to become major concern amongst the IBS players that have led to delays, disputes, payment and cash flow issues in their projects. Formulating a dedicated standard form of contract for IBS construction approach is necessary to address the concerns. Therefore, the aim of the main research is to formulate the standard form of contract for IBS projects that will assist authorities and IBS industry players in mitigating the issues and challenges from the contractual perspectives. However, this paper will only present the literature reviews and findings from a preliminary survey conducted to establish pertinent contractual issues and challenges on the subject matter.

    Full Text Available People-centered innovation is a paradigm shift in the construction industry. It is derived from the supposition that people not methods, schedules, or budgets deliver projects. Our data suggest that a multilevel, multidisciplinary project team through shared vision, values, and a common vernacular defines, designs, and delivers more successful projects than traditional methods. These projects meet the needs of shareholders, the community, stakeholders, and the planet. We employ the concepts of emotional intelligence and agency theory to explain an integrated project delivery (IPD construction project using lean tactics that not only delivered, but also exceeded expectations resulting in a six-month schedule acceleration and $60M savings over the original estimated cost of the project calculated assuming traditional project delivery methods. The safety rating for this project was 50% better than the national average and the expected improvement in operating margin for the new building is 33% greater. This paper introduces the notion of people-centered innovation to an industry that has struggled to adapt and show positive results over recent decades. Our case study describes the significance of people-centered innovation in construction project delivery. We discuss the implications for the construction industry going forward.

    2015-05-01

    Full Text Available There have been numerous concerns about the lack of productivity improvement in the New Zealand construction industry.  The aim of this paper, therefore, is to determine the main drivers of productivity in the industry. The research used is a two-staged data envelopment analysis approach to achieve the aim. In terms of improvements to the productivity of construction in New Zealand, the study found that although there is a potential for gains through the greater use of research and development, apprentice training and degree education, as well as the consolidation of some building companies, there will be some limits to the gains that might be made. One main implication of the findings of the study, therefore, is that a renewed focus on education and skills training should be a priority of companies and policy makers in New Zealand.

  11. A CONCEPTUAL DISASTER RISK REDUCTION FRAMEWORK FOR HEALTH AND SAFETY HAZARDS IN THE CONSTRUCTION INDUSTRY

    Directory of Open Access Journals (Sweden)

    Amir S. GOHARDANI

    2013-06-01

    Full Text Available The health and safety hazard status of construction workers is constantly challenged by the projects in the built environment. In this article, various aspects of health and safety hazards for construction workers have been reviewed and investigated through a disaster risk reduction prism. This approach has further led to the perception of glancing at the construction sector as an ongoing disaster zone and equally provides a new management perspective. From this perspective, the occurrence of a disaster within the construction sector corresponds to the temporary or permanent ill-health or death of a construction worker. Geographical location is one of the factors that play an important role in addressing the health and safety hazards for construction workers. In addition to the location, geographical considerations equally encapsulate regional, cultural, governmental and work ethical effects. These effects may potentially contribute to disparities in the construction sector. With an increasing level of understanding for health and safety hazards in the construction domain, more efficient prevention measures can be taken in order to enable a disaster management cycle, capable of responding to the rigorous demands of the construction sector.

  13. Local exhaust ventilation for the control of welding fumes in the construction industry--a literature review.

    Science.gov (United States)

    Flynn, Michael R; Susi, Pam

    2012-08-01

    Arc welding is a common unit operation in the construction industry, where frequent changes in location and welding position make it more difficult to control fume exposures than in industries where fixed locations are the norm. Welders may be exposed to a variety of toxic airborne contaminants including manganese (Mn) and hexavalent chromium (CrVI). Local exhaust ventilation (LEV) is a well-known engineering control for welding fumes but has not been adopted widely in the construction industry. This literature review presents data on the performance of a variety of LEV systems for welding fume control from the construction (five references), shipyard (five references), and other industries. The studies indicate that LEV can reduce fume exposures to total particulate, Mn, and CrVI to levels below currently relevant standards. Field studies suggest that 40-50% or more reduction in exposure is possible with portable or fixed LEV systems relative to natural ventilation but that correct positioning of the hood and adequate exhaust flow rates are essential. Successful implementation of extraction guns for gas metal arc welding (GMAW) and flux core arc welding has been demonstrated, indicating that a successful balance between extraction airflow and shielding gas requirements is possible. Work practices are an important part of achieving successful control of fume exposures; in particular, positioning the hood close to the arc, checking exhaust flow rates, and avoiding the plume. Further research is needed on hood size effects for controlling welding fume with portable LEV systems and identifying and overcoming barriers to LEV use in construction.

  15. Skilled labour supply in the South African construction industry: The nexus between certification, quality of work output and shortages

    Directory of Open Access Journals (Sweden)

    Abimbola O. Windapo

    2016-02-01

    Full Text Available Orientation: Construction human resource management.Research purpose: The study examines the skilled labour supply in the South African construction industry and determines whether there is a relationship between trade certification, quality of work output and scarce labour skills.Motivation for the study: The rationale for the investigation is based on the view of scholars that a skilled labour shortage is preponderant in the South African construction industry even though there is a high level of youth unemployment in South Africa and that the perceived skills shortage contributes to a decrease in productivity and product quality.Research design, approach and method: The paper reviews relevant literature and employs a mixed method research approach in collecting empirical data from contracting companies within the Western Cape Province of South Africa that are listed on the Construction Industry Development Board contractor register.Main findings: The study demonstrated that there is no shortage of manpower, but there is a shortage of qualified or skilled tradesmen, such as electricians, plumbers, welders, fitters and carpenters, whose professions are more technical and require formal training and certification. The level of supply of skilled tradesmen is attributed to the lack of high-quality basic education, the state of the economy, compulsory certification of tradesmen and an ageing workforce. It was also found that there is a significant relationship between skilled labour shortages and the requirement that labour be certified and that work output is unsatisfactory when there is no certification requirement.Practical/managerial implications: Based on these findings, the study concludes that skilled labour shortages and poor work output quality continue to be experienced in the South African construction industry when workers are unable to obtain formal certification for informal work experience acquired through years of practice on

    Panuwatwanich, Kriengsak; Al-Haadir, Saeed; Stewart, Rodney A

    2017-03-01

    Over the last three decades, safety literature has focused on safety climate and its role in forecasting injuries and accidents. However, research findings regarding the relationships between safety climate and other key outcome constructs are somewhat inconsistent. Recent safety climate literature suggests that examining the role of safety motivation may help provide a better explanation of such relationships. The research presented in this article aimed to empirically analyse the relationships among safety motivation, safety climate, safety behaviour and safety outcomes within the context of the Saudi Arabian construction industry. A conceptual model was developed to examine the relationships among four main constructs: safety motivation, safety climate, safety behaviour and safety outcomes. Based on the survey data collected in Saudi Arabia from site engineers and project managers (n = 295), statistical analyses were carried out, including confirmatory and exploratory factor analysis, and structural equation modelling to assess the model and test the hypotheses. The main results indicated that safety motivation could positively influence safety behaviour through safety climate, which plays a mediating role for this mechanism. The results also confirmed that safety behaviour could predict safety outcomes within the context of the Saudi Arabian construction industry.

    Full Text Available The main purpose of this study is to examine the relationship between organisational culture (OC and Total Quality Management (TQM, and the influence of TQM implementation on organisational performance improvement within the context of the Vietnamese construction industry. A survey was conducted with 104 respondents from Vietnamese construction firms, using validated survey instruments developed in past research. Analysis techniques include cluster analysis and Structural Equation Modelling. Findings showed that Vietnamese construction firms are dominated by clan and hierarchy cultures rather than adhocracy and market cultures according to Competing Value Framework (CVF of OC classification. Furthermore, it was found that organisations dominated by either clan or adhocracy cultures could provide a favourable environment for successful TQM implementation, whereas this is not the case for those dominated by both market and hierarchy cultures. This study also confirmed the significant and positive relationship between TQM implementation and organisational performance improvement.

    Full Text Available Complexity is one of the most important issues influencing success of any construction project and there are literally different studies devoted to detect important factors increasing complexity of projects. During the past few years, there have been growing interests in developing mass construction projects in Iran. The proposed study of this paper uses Delphi technique to find out about important factors as barriers of construction projects in Iran. The results show that among 47 project complexity factors, 19 factors are more important than others are. The study groups different factors into seven categories including environmental, organizational, objectives, tasks, stakeholders, technological, information systems and determines the relative importance of each. In each group, many other sub group activities are determined and they are carefully investigated. The study provides some detailed suggestions on each category to reduce the complexity of construction project.

    Parisé, Jason; Walker, Tony R

    2017-10-01

    Electricity generation from wind energy has proliferated throughout North America and will continue to grow. Given Canada's expected increase in wind energy capacity, consideration of the potential adverse impacts to bird and bat populations is prudent given their sensitivity to these projects. The province of Ontario, Canada is currently the leading jurisdiction for wind energy development, and for provincial guidance on pre- and post-construction monitoring. With uniform monitoring guidance in Ontario, wind energy proponents, and third-party consultants, have developed post-construction monitoring protocols that meet provincial guidance, while also providing standardized reporting. In Atlantic Canada, post-construction guidelines vary between provinces, depending mostly on guidance from the Environment Canada Canadian Wildlife Service and relevant provincial agencies. To ensure quality post-construction monitoring results in Atlantic Canada and other provinces, it is imperative that all Canadian provinces adopt similar approaches to those employed in Ontario. This paper reviews major causes of bird and bat mortalities; reviews Canadian federal and Ontario provincial bird and bat monitoring guidelines to elucidate gaps between environmental assessment (EA) theory and application; summarizes post-construction monitoring protocols from eight bird and bat post-construction monitoring programs used in Ontario; and, proposes recommendations to support future wind development opportunities across Canada and specifically in Atlantic Canada.

    2010-10-01

    The Government of the Hong Kong Special Administrative Region (SAR) has implemented different safety initiatives to improve the safety performance of the construction industry over the past decades. The Pay for Safety Scheme (PFSS), which is one of the effective safety measures launched by the government in 1996, has been widely adopted in the public works contracts. Both the accident rate and fatality rate of public sector projects have decreased noticeably over this period. This paper aims to review the current state of application of PFSS in Hong Kong, and attempts to identify and analyze the perceived benefits of PFSS in construction via an industry-wide empirical questionnaire survey. A total of 145 project participants who have gained abundant hands-on experience with the PFSS construction projects were requested to complete a survey questionnaire to indicate the relative importance of those benefits identified in relation to PFSS. The perceived benefits were measured and ranked from the perspectives of the client and contractor for crosscomparison. The survey findings suggested the most significant benefits derived from adopting PFSS were: (a) Increased safety training; (b) Enhanced safety awareness; (c) Encouragement of developing safety management system; and (d) Improved safety commitment. A wider application of PFSS should be advocated so as to achieve better safety performance within the construction industry. It is recommended that a similar scheme to the PFSS currently adopted in Hong Kong may be developed for implementation in other regions or countries for international comparisons.

    Full Text Available The urban nucleus of the Porcelain Factory of Vista Alegre reveals a special interest in terms of the evolution of the traditional adobe construction in the town of Ílhavo, located in the district of Aveiro. Presenting a structured philosophy of intervention in the territory since its very beginning, it possesses a rich heritage in the field of construction and architecture. The measures planned and implemented in the second phase of Vista Alegre growth reporting its beginning to the ends of the 30's, and along the 40's, confirm it both in the rehabilitation, extension and new constructions in adobe masonry. Those measures were implemented during the structural changes of the Industrial Unit administration that only until this period belonged to the family of its founder. These changes creates one of the focus of innovation in the region, with new construction strategies and solutions in adobe buildings, which will prolonged the period of use of this construction system, noticeable in buildings dated of 1958 in the Vista Alegre and at least in 1970 in the town.

    Full Text Available Construction industry is one of the major drivers of the economic sustainability of China’s provinces. An investigation of the status of the construction industry in China is needed to find out its maturity and health. The results of this investigation may help China define the impact factors required in order to promote the growth level of its construction industry. This research assesses the growth level of the construction industry in Shaanxi Province, China. This study utilizes both the original average score method and the newer entropy method to analyze the growth level of the construction industry based on its growth management model and growth drivers. An empirical survey of this research includes 123 construction companies in Shaanxi Province. The results show that the entropy method is better than the average score method to use when analyzing the maturity status of a local industry for future development. The maturity level of Shaanxi’s construction industry lies on the second tier in a four-tier ranking system. The advanced professional skills of project management are critically needed for future growth. Brand building is the most important factor needed to drive up Shaanxi’s construction industry. Standardization, knowledge management through lessons learned, and cost management for budget control by using information systems are required for Shaanxi’s construction project management. The Excellent Project Management Model of China is often used in Chinese project knowledge management. After maturity analysis, China’s local industries would be able to develop a sustainable strategy for optimizing their outcomes by removing the hurdles preventing future growth.

  14. Beyond knowledge transfer: The social construction of autonomous academic science in university-industry agricultural biotechnology research collaborations

    Science.gov (United States)

    Biscotti, Dina Louise

    Autonomy is a social product. Although some might view autonomy as the absence of social interference in individual action, it is in fact produced through social institutions. It enables social actors to act; it is the justification for the allocation of enormous public resources into institutions classified as "public" or "nonprofit;" it can lead to innovation; and, significantly, it is key to the public acceptance of new technologies. In this dissertation, I analyze the social construction of autonomy for academic science in U.S. university-industry agricultural biotechnology research collaborations. University-industry relationships (UIRs) are a site of concern about the influence of commercial interests on academic science. Agricultural biotechnology is a contentious technology that has prompted questions about the ecological and public health implications of genetically-modified plants and animals. It has also spurred awareness of the industrialization of agriculture and accelerating corporate control of the global food system. Through analysis of in-depth interviews with over 200 scientists and administrators from nine U.S. research universities and thirty agricultural biotechnology companies, I find that both the academy and industry have a vested interest in the social construction of the academy as an autonomous space from which claims to objective, disinterested scientific knowledge can be made. These claims influence government regulation, as well as grower and public acceptance of agricultural biotechnology products. I argue that the social production of autonomy for academic science can be observed in narratives and practices related to: (1) the framing of when, how and why academic scientists collaborate with industry, (2) the meanings ascribed to and the uses deemed appropriate for industry monies in academic research, and (3) the dissemination of research results into the public domain through publications and patents. These narratives and practices

    Full Text Available In the respect of value, public procurement in the construction industry belongs to one of the largest ones in the domestic market. Therefore, green procurement for construction works should become the center of attention of public authorities in a broad sense, due to its scale and importance for the sustainable development. The authorities and contracting entities who spend public money should have the opportunity to apply such legal articles and instruments that allow them to both optimize public expenditures and consider the environmental factor, such as decreasing carbon emission. To make the idea of sustainable development a reality as European Union’s the most vital aim, EU law is implemented in Poland. Local authorities’ duty is to appropriately shape their policies and use the vital instrument of sustainable development, namely green public procurement. This paper presents a comparative analysis of legal regulations to illustrate the actual Polish and EU laws concerning the construction industry. Even though the generally applicable law allows to implement the idea of sustainable development efficiently, local self-government units in their regional policies do not report any need for specific solutions, or they do so only occasionally.

    Typha domingensis had become the dominant species after 2 years of operation of a wetland constructed for metallurgical effluent treatment. Therefore, the main purpose of this study was to investigate its ability to tolerate the effluent and to maintain the contaminant removal efficiency of the constructed wetland. Plant, sediment, and water at the inlet and outlet of the constructed wetland and in two natural wetlands were sampled. Metal concentration (Cr, Ni, and Zn) and total phosphorus were significantly higher in tissues of plants growing at the inlet in comparison with those from the outlet and natural wetlands. Even though the chlorophyll concentration was sensitive to effluent toxicity, biomass and plant height at the inlet and outlet were significantly higher than those in the natural wetlands. The highest root and stele cross-sectional areas, number of vessels, and biomass registered in inlet plants promoted the uptake, transport, and accumulation of contaminants in tissues. The modifications recorded accounted for the adaptability of T. domingensis to the conditions prevailing in the constructed wetland, which allowed this plant to become the dominant species and enabled the wetland to maintain a high contaminant retention capacity.

    The character of construction projects exposes front-line workers to dangers and accidents. Safety climate has been confirmed to be a predictor of safety performance in the construction industry. This study aims to explore the underlying mechanisms of the relationship between multilevel safety climate and safety performance. An integrated model was developed to study how particular safety climate factors of one level affect those of other levels, and then affect safety performance from the top down. A questionnaire survey was administered on six construction sites in Vietnam. A total of 1030 valid questionnaires were collected from this survey. Approximately half of the data were used to conduct exploratory factor analysis (EFA) and the remaining data were submitted to structural equation modeling (SEM). Top management commitment (TMC) and supervisors' expectation (SE) were identified as factors to represent organizational safety climate (OSC) and supervisor safety climate (SSC), respectively, and coworkers' caring and communication (CCC) and coworkers' role models (CRM) were identified as factors to denote coworker safety climate (CSC). SEM results show that OSC factor is positively related to SSC factor and CSC factors significantly. SSC factor could partially mediate the relationship between OSC factor and CSC factors, as well as the relationship between OSC factor and safety performance. CSC factors partially mediate the relationship between OSC factor and safety performance, and the relationship between SSC factor and safety performance. The findings imply that a positive safety culture should be established both at the organizational level and the group level. Efforts from all top management, supervisors, and coworkers should be provided to improve safety performance in the construction industry.

    Full Text Available This study explored the linkage between personal competencies and leadership behaviours as well as their influences on leadership outcomes and subordinates’ work performance. Personal competencies were measured using the Project Manager Competency Development (PMCD tool. Leadership behaviours and outcomes were measured using Multifactor Leadership Questionnaire (MLQ. Data was collected from construction projects in Thailand. Findings revealed that leadership outcomes have significant positive relationship with all personal competencies specified in the PMCD framework, every factor in the transformational style and contingent reward factor in the transactional style. Transformational leaders tend to produce high work quality, work quantity, and problem solving creativity from subordinates. Findings further verified that all PMCD personal competencies have significant positive relationship with every factor in the transformational style. It implies that project managers who apply the transformational style and/or have high personal competencies indicated in PMCD framework are likely to generate greater leadership outcomes and work performance on construction projects.

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

    Full Text Available Geo- and hydro-meteorological disasters typically caused disruptive impact to road networks due to damaged road infrastructure, which in turn disconnect access to and isolate the disaster affected areas. Road clearing work and emergency road recovery operation are considered a priority to reconnect the access during post-disaster emergency response. However, the operation is not always smooth and in many cases delayed due to various problems. An investigation is conducted to understand the current practice of post-disaster emergency road recovery operation in Indonesia and to study possible participation of construction industry in order to improve its effectiveness. In-depth interviews with Local Disaster Management Agencies (BPBDs and local road agencies in West Java Province were conducted to understand current practices in emergency road recovery operation and to view perspectives on local contractor participation. The surveys showed supports from the local governments for contractor involvement as long as it is still under guidance of related agencies (Ministry of Public Works and Housing despite some possible obstacles from the current regulation that may hamper contractors’ participation, which indicate that there is a potential role of construction industry for more effective post-disaster emergency response, provided that contractor associations are involved and existing procurement regulation is improved.

    Process improvement is a topic gaining considerable attention in literature. For the processes of Engineering, Procurement, Construction and Maintenance (i.e. EPCM) projects in the oil and gas industry, no frameworks exist that can guide these firms in the management of these processes. Using a detailed gap analysis we map the typical processes of EPCM-organisations onto the Capability Maturity Model Integrated (CMMI), a stepwise process improvement model that is widely used in the software industry. Our main contribution is the conclusion that CMMI can benefit the management of EPCM-processes to a large degree, since it gives direction to the improvement of a considerable set of processes within EPCM-projects. Additional insight is given into the scientifically neglected area of learning between projects and the relationship between an organisation's goals and targeted areas of process improvement. These issues are absent in CMMI so further research is needed to develop framework support for, amongst others, downstream processes (construction and maintenance), learning between projects and goal driven process improvement.

    This study evaluates and contrasts the management practice and the performance that characterise Environmental Impact Assessments (EIA) in Italy and in the UK. The methodology relies on the investigation of six carefully selected case studies, critically reviewed by referring to EIA and project design information, as well as collecting the opinion of key project participants. The study focuses on the construction industry and on specific key sectors like infrastructure for transport and renewable energy and commercial and tourism development. A main term of reference for the analyses has been established by critically reviewing international literature so as to outline common good practice, requirements for the enhancement of sustainability principles and typically incurred drawbacks. The proposed approach enhances transfer of knowledge and of experiences between the analyzed contexts and allows the provision of guidelines for practitioners. Distinctive differences between the UK and the Italian EIA systems have been detected for pivotal phases and elements of EIA, like screening, scoping, analysis of alternatives and of potential impacts, definition of mitigation strategies, review, decision making, public participation and follow up. - Highlights: Black-Right-Pointing-Pointer The Italian and the UK Environmental Impact Assessment systems are compared. Black-Right-Pointing-Pointer The research is centred on the construction industry. Black-Right-Pointing-Pointer Issues and shortcomings are analysed by investigating six case studies. Black-Right-Pointing-Pointer Integration of EIA with sustainability principles is appraised. Black-Right-Pointing-Pointer General guidelines are provided to assist practitioners in the two national contexts.

    Full Text Available Given that any construction project is inherently a human endeavour, it follows that issues of trust are significant in terms of the stakeholder interactions that deliver eventual project outcomes.  Previous research indicates that the relational basis upon which projects are undertaken are intended to influence the likelihood of trusting relationships between stakeholders.  Thus, experiences of trust in a construction project environment are likely to be influenced by the contextual specifics of respective transactional and relational contracting (RC procurement mechanisms, given the divergent theoretical principles upon which they are founded.  The influence of trust has therefore been examined through the lived experiences of construction practitioners.  A phenomenological interview study consisting of thirty-five (35 participants was conducted with sensitivity to the procurement of experiences being recounted. Issues of trust were shown to be integral to stakeholder experiences in both procurement environments, with the benefits of trust acknowledged in many instances.  However, little understanding was evident regarding methods for building and maintaining trust, nor for repairing trust when problems arose. Importantly, despite the differing principles that underpin transactional and relational procurement, and particularly the contention that relational procurement would increase trust between trading partners, this was not evident; with individual personalities and appropriate risk apportionment shown to be greater influences upon the likelihood of trusting relationships.  It is reasonable to conjecture that relational contracts actually diminish the need for trust, given that the objective is to reduce uncertainty through formulaic approaches to risk distribution and reward; the absence of risk negates the need for trust.  Ultimately, the potential to deliver improved project outcomes as a result of proactive approaches to

    Full Text Available Regulations in the Building Industry are becoming increasingly complex and involve more than one technical area, covering products, components and project implementations. They also play an important role in ensuring the quality of a building, and to minimize its environmental impact. Control or conformance checking are becoming more complex every day, not only for industrials, but also for organizations charged with assessing the conformity of new products or processes. This paper will detail the approach taken by the CSTB (Centre Scientifique et Technique du Bâtiment in order to simplify this conformance control task. The approach and the proposed solutions are based on semantic web technologies. For this purpose, we first establish a domain-ontology, which defines the main concepts involved and the relationships, including one based on OWL (Web Ontology Language [1]. We rely on SBVR (Semantics of Business Vocabulary and Business Rules [2] and SPARQL (SPARQL Protocol and RDF Query Language [3] to reformulate the regulatory requirements written in natural language, respectively, in a controlled and formal language. We then structure our control process based on expert practices. Each elementary control step is defined as a SPARQL query and assembled into complex control processes “on demand”, according to the component tested and its semantic definition. Finally, we represent in RDF (Resource Description Framework [4] the association between the SBVR rules and SPARQL queries representing the same regulatory constraints.

    Full Text Available Conceptualizing family in contemporary society is an exercise that requires deep reflection, as the cultural industry through the media sprays and brings up a series of biographical experiences and organizational models that contribute to deepen and broaden the stigmata reinforcing stereotypes. Thinking about the family concept of questioning we aim of this study to understand how the cultural industry contributes to the family of concept formation in view of pedagogy students in the program as a condition of their future professional activities. Students of the first year of the mentioned course of a Public University of the State of Paraná participated in the research, through debates about the concept of family using as strategies texts, sources available in the internet and in television advertisements. We conclude that the research subjects view points to a classic vision of family, based on defining characteristics. It is necessary to question the reality of families in contemporary times in the training process of these individuals and the complexity of the factors that interfere with its concept of the family, therefore, it must be understood historically and analyzed in their specificity by adopting certain pedagogical assumptions.

  12. The use of Game Theory to solve conflicts in the project management and construction industry

    Directory of Open Access Journals (Sweden)

    José Ramón San Cristóbal

    2015-01-01

    Full Text Available A typical construction project involves a wide range of disparate professionals, in many cases geographically distributed, working together for a relatively short period of time on the design and construction of a facility. Since organizations are becoming flatter, culturally rich, geographically diverse and intensely competitive, the possibilities for conflict in such environments are greater. Negotiation is an important aspect of a project and plays an important role in resolving claims, preventing disputes, and keeping a harmonious relationship between project participants. Part of any project manager’s role as a leader is to recognize conflict, understand the sources of conflict and manage it, and to do this a project manager must be able to understand the basics of negotiation theory and have sufficient competencies to lead in such situations. To address the complex technical and human issues in negotiation, different negotiation theories and models are available which mainly include game theory, economic theory, and behavior theory. Since Game Theory provides, by its very nature, the appropriate tools for the analysis and eventual solution of conflicts of any kind, this paper uses a model based on Game Theory in order to identify the activities that are responsible for the delays in a project and divide the costs among them.

  13. Identifying Sustainable Wood Sources for the Construction Industry: A Case Study

    Full Text Available Wood is generally considered as a sustainable construction material. However, there are not sufficient wood resources in many countries or regions, especially those short of land resources. These countries and regions have to import wood from overseas. Therefore, it is imperative to determine how to choose sustainable importing sources in order to improve the sustainability performance of using wood in construction. This study compares the sustainability performance of wood imported from different regions by considering wood harvesting, manufacture, and transportation. A framework accounting energy consumption and CO2 emissions is developed for sustainability assessment. The results show that importing wood from Canada, Australia, and New Zealand to Taiwan demands a relatively lower amount of energy than from other regions. Specifically, importing wood from Canada (West demands the lowest amount of energy (2095 MJ/m3, while importing wood form Brazil consumes the highest amount of energy (5356 MJ/m3. In addition, findings showed that the CO2 emissions generated from importing wood from Sweden are significant lower than those from other regions, although the energy consumed during the importing process is relatively high. The study also revealed that the wood manufacturing process and marine transportation contribute to the most energy consumption and CO2 emissions among all importing processes analysed from most of studied regions.

    The current study examines and compares the relationship between both macroeconomic and industry-specific business cycle indicators, and work-related injuries among construction workers in Denmark using emergency department (ED) injury data and also officially reported injuries to the Danish Working Environment Authority (WEA). The correlations between ED and WEA injury data from the catchment area of Odense University Hospital during the period 1984-2010 were tested separately for variability and trend with two general macroeconomic indicators (gross domestic product and the Danish unemployment rate) and two construction industry-specific indicators (gross value added and the number of employees). The results show that injury rates increase during economic booms and decrease during recessions. However, the regression coefficients were generally weak for both the ED (range 0.14-0.20) and WEA injuries (range 0.13-0.36). Furthermore, although there is some variability in the strength of the relationship of the different business cycle indicators, the relationships are generally not stronger for the WEA injuries than for the ED injuries, except for general unemployment. Similarly, no substantial differences in strength of relation between industry-specific and macroeconomic indicators were identified. The study shows that there was no difference in the relationship between business cycle indicators, and WEA and ED injury data. This indicates that changes in reporting behaviour do not seem to play a major role in the relation between the business cycle and workplace injuries in a Danish context.

    European Directive 2002/44/EC defines employers' responsibilities in the risk management of hand-arm vibration (HAV). However, the directive is still not completely implemented in all risk industries. The aim of our study was to determine whether it is possible to improve the recognition and management of the risks of HAV at workplaces with a one-year information campaign. A questionnaire on opinions and measures for controlling HAV exposure at workplaces was sent to all occupational safety representatives and occupational safety managers in the construction and metal industry in Finland (n=1887) and once again to those who responded to the first questionnaire (n=961) one year after the campaign. The campaign increased recognition of HAV in risk assessment from 57.0% to 68.3% (p=.001), increased measures to decrease exposure to HAV from 54.6% to 64.2% (p=.006) and increased the number of programmes to control the risks due to HAV (pconstruction and metal industries, proved to be effective in increasing the awareness of the risks of HAV and the measures needed to control exposure to HAV. A similar campaign can be recommended in the case of risks specific to certain occupations.

    This paper analyzes the significant scientific publications worldwide for the last 15years concerning construction ceramics (predominantly brick) made with various inorganic industrial wastes added to the ceramic raw material for the improvement of properties and for eco-friendly disposal. The information gap resulting from the lack of mentions of the Russian publications on this subject in English-language reviews is filled. The paper includes brief summaries of 34 dissertations and 29 patents issued in Russia since 2000. The waste additives described in these summaries are grouped by origin type (mining industry waste, ore enrichment waste, metallurgical waste, sludge, ashes, cullet, large-capacity building wastes and waste from various chemical production processes) with the ceramic mixture compositions, molding and firing conditions, final strength, water absorption and other parameters of the final ceramic samples reported. Russian scientists have expanded the nomenclature of each group of wastes significantly upon addition to the list described in English-language reviews for 2000-2015.

    This study evaluated the mortality of 27,362 members of the U.S. Carpenters' Union who died in 1987-1990. Age-adjusted proportionate mortality ratios (PMRs) and proportionate cancer mortality ratios (PCMRs) were computed using the U.S. age-, gender-, and race-specific proportional mortality for the years of the study. For white male carpenters who were last employed while in construction industry locals, raised mortality was observed for lung cancer (PCMR = 107, CI = 103, 111), bone cancer (PMR = 181, CI = 107, 286), asbestosis (PMR = 283, CI = 158, 457), emphysema (PMR = 115, CI = 102, 130), transportation injuries (PMR = 121, CI = 109, 135), and falls (PMR = 122, CI = 104, 142). For white male carpenters who were last employed while in industrial wood products locals, significantly raised mortality occurred for stomach cancer (PMR = 187, CI = 136, 250), male breast cancer (PCMR = 469, CI = 128, 720), and transportation injuries (PMR = 136, CI = 110, 173). Excess breast cancer was associated with last employment inn wood machining trades. Nasal cancer mortality was not elevated. A total of 121 mesotheliomas were observed. Contributing cause of death analyses revealed raised mortality for these and additional causes; 4,594 (18%) death certificates mentioned occupational and other lung disease as a contributing factor, resulting in significantly elevated mortality. These data show that construction carpenters have moderately elevated mortality for the diseases caused by asbestos (lung cancer and malignant mesothelioma) and from traumatic injuries. The finding of elevated mortality for stomach, bone, and breast cancer was unexpected and requires further evaluation of possible occupational factors. This study confirms that construction carpentry is an extremely hazardous trade. The data suggest that additional preventive action guarding against asbestos exposure and occupational injury is urgently needed in this occupation.

    Full Text Available The aim of this research is to establish a set of employability indicators that capture the competency requirements and performance expectations that solar energy enterprises have of their employees. In the qualitative component of the study, 12 administrators and 32 engineers in the industry were interviewed, and meetings with focus groups were conducted to formulate a questionnaire for a survey of Taiwanese solar energy companies for the confirmation and prioritisation of the employability indicators. On the basis of the results of the quantitative component, an interpretational model relating competence, job performance, working attitude, and employability for solar corporation recruitment and training purposes as well as for school curricular development was developed. The interpretation model formulated effectively interprets the relationship between solar enterprises’ expectations and students’ employability. The research contributes a framework for the selection and cultivation of talent, as well as providing a basis for fundamental development of the solar engineering curriculum.

    Large-scale construction projects such as power plants bring both benefits and problems for communities near the project sites. Those communities need to know about possible socio-economic effects and ways to deal with them. It is important for the community, government, and industry to know about the likely effects of construction projects. Then they can assess more accurately the costs and the benefits of the project and therefore in a better position to seek or allocate financial resources. Most importantly, they can develop planning strategies prior to the project. Advance planning helps to prevent some adverse effects, to minimize or mitigate others, and to enhance beneficial ones. This guide provides information that will help local people, government officials, and developers to develop plans for the successful management of large-scale construction projects. A traditional planning model is adopted in which impact issues are identified, strategies to deal with them are selected and implemented, outcomes are monitored, and adjustments are made as necessary. The guide is organized into four sections: the planning process; the impact assesment and screening process; possible management strategies dealing with issues such as employment, transportation, accommodation, community services, funding, and wind-down; and a list of supplementary sources of information about community planning, impact assessment, and growth management. 30 refs., 3 figs., 2 tabs.

    Safety climate measurements can be used to proactively assess an organization's effectiveness in identifying and remediating work-related hazards, thereby reducing or preventing work-related ill health and injury. This review article focuses on construction-specific articles that developed and/or measured safety climate, assessed safety climate's relationship with other safety and health performance indicators, and/or used safety climate measures to evaluate interventions targeting one or more indicators of safety climate. Fifty-six articles met our inclusion criteria, 80% of which were published after 2008. Our findings demonstrate that researchers commonly defined safety climate as perception based, but the object of those perceptions varies widely. Within the wide range of indicators used to measure safety climate, safety policies, procedures, and practices were the most common, followed by general management commitment to safety. The most frequently used indicators should and do reflect that the prevention of work-related ill health and injury depends on both organizational and employee actions. Safety climate scores were commonly compared between groups (e.g. management and workers, different trades), and often correlated with subjective measures of safety behavior rather than measures of ill health or objective safety and health outcomes. Despite the observed limitations of current research, safety climate has been promised as a useful feature of research and practice activities to prevent work-related ill health and injury. Safety climate survey data can reveal gaps between management and employee perceptions, or between espoused and enacted policies, and trigger communication and action to narrow those gaps. The validation of safety climate with safety and health performance data offers the potential for using safety climate measures as a leading indicator of performance. We discuss these findings in relation to the related concept of safety culture and

    Total (direct and indirect) energy requirements of the construction industry for 1967 were determined in order to examine the potential for energy savings. The Energy Input/Output Model developed at the Center for Advanced Computation, University of Illinois, was expanded to include a detailed breakdown of the industry and energy intensities of 49 building construction (new and maintenance) sectors and of the overall building construction industry were determined for 1967. The latter figure was computed at about 70,000 Btu/$, i.e., the construction industry on the average required about 70,000 Btu of direct and indirect energy per dollar of output produced. In addition, total energy requirements to final demand were developed for the construction industry for 1967. The overall industry required about 6000 trillion Btu, or about nine percent of the total U.S. energy requirement. Energy requirements were further broken down according to goods and services purchased by individual construction sectors, and energy distribution patterns were determined. Energy cost per unit for several input materials to construction were calculated, as well as energy cost per square foot for various building sectors in 1967. Laboratories and hospitals required the most energy per square foot (2,073,755 Btu/ft/sup 2/ and 1,722,172 Btu/ft/sup 2/, respectively), while warehouses required the least (558,403 Btu/ft/sup 2/). Finally, a prototypical study was conducted to determine industries in which direct energy use led to a significant amount of energy embodied in new construction for 1967. The resulting energy flow chart is included.

    Safety climate, a group-level measure of workers' perceptions regarding management's safety priorities, has been suggested as a key predictor of safety outcomes. However, its relationship with actual injury rates is inconsistent. We posit that safety climate may instead be a parallel outcome of workplace safety practices, rather than a determinant of workers' safety behaviors or outcomes. Using a sample of 25 commercial construction companies in Colombia, selected by injury rate stratum (high, medium, low), we examined the relationship between workers' safety climate perceptions and safety management practices (SMPs) reported by safety officers. Workers' perceptions of safety climate were independent of their own company's implementation of SMPs, as measured here, and its injury rates. However, injury rates were negatively related to the implementation of SMPs. Safety management practices may be more important than workers' perceptions of safety climate as direct predictors of injury rates. © 2017 Wiley Periodicals, Inc.

    The development of blast furnace slag sand stabilisation began in the middle of the 1980's. The objective was to develop a method to prevent the damage of the load-bearing layers top part (rock materials pulverisation). With cooperation of Rautaruukki Oy and SKI Company a method was developed which fulfills the given edge conditions. At the same time an environment friendly method was achieved which makes good use of industrial by-product, blast furnace slag. The new method clearly increase the lifetime of the structure. The use of blast furnace slag sand stabilisation expanded in 1991 when more powerful rotavators for stabilisation work were available. The compression strength of the stabilised material, soil cement, at the age of 90 days is 3,0 MPa. The bearing values at the age on one year have been from 700-800 MN/m{sup 2}. Another good property is its ability to reset if the stabilised structure is damaged (cracked). The method has been used mainly in the Northern Finland area, but nowadays the economic range of use is the whole country. (orig.)

    Full Text Available Formation of the pricing system and underlying investment and construction activities were analyzed by the authors in their research. It is noteworthy that the pricing system has a common basis with other human systems, as it incorporates such constituents as process, people, software, etc. Correct interaction between these elements ensures conformity between the anticipated and the practical performance of the system. The basis for the effective operation of the existing system and reduction of potential risks consists in early identification and analysis of requirements set by the user. Absent of implementation of an effective requirement management process, the pattern of the system development will look chaotic and unpredictable. In the process of the data analysis, the data set is converted into a set of the user requirements describing the anticipated behavior of the system in the course of its interaction with the operating environment. The requirements of users comprise an important constituent of the system design. They affect the entire development process from the beginning to the very end. In accordance with the principles of the system engineering, the authors have identified the key pricing system parameters; their implementation assures the appropriate functionality with a view to the formation of the contract price at various stages of the life-cycle of the investment project. Analysis of the above requirements makes it possible to convert them into a technical vision of the desired product that can demonstrate the required functionality. The methodology proposed by the authors contemplates decomposition of the levels of requirements; therefore, the authors employ a three-level model that describes the expected functionality of the system. The model includes an organizational level (basic processes, participants, information flows, a methodological level (method of calculating the cost of design, construction and operation

    Full Text Available This study considered the problem of understanding and use of risk management methods in construction projects and their representation in the literature and their practical application. Research of trends in risk management was conducted using studies from the EBSCO database that were published in the period from 1999 to 2015. The focus included the development of two terms, namely traditional and holistic approach to risk management as well as to uncertainty and opportunity management. The trend of leading standards in the field of project management, PMBoK and ISO 31000 indicated full support for the modernization of risk management that focused on the risks as well as potential opportunities in the project. The findings also revealed that the global practices continued to lack awareness of risk management and its benefits for project goals. A similar situation was found in Croatia by observing project management practices in two case studies, namely Project Zagrebačka obala in Rijeka and a Project of SEECEL Zagreb. Primarily, the lack of education and communication between experts are important issues requiring attention in practice and academics. It is necessary to gradually introduce standards over time to prepare for progress in managing uncertainties and adopting more holistic approaches.

    Full Text Available Globally, falls from height (FFH are a substantial public health jeopardy and are among the important leading causes of serious and fatal injuries for construction workers. A comprehensive understanding of the causal factors in FFH incidents is urgently required; however, the literature appears to lack a scientific review of FFH. In this study, 297 articles that contribute to the topic of fall incidents were reviewed. Seventy-five (75 articles met the criteria for relevance and were aggregated in a database to support a critical review. A synthesis of macro-variables approach was adopted rather than a structured meta-analysis. Such a method of analysis provides the flexibility to combine previous studies' findings. The most common factors associated with FFH are risky activities, individual characteristics, site conditions, organizational characteristics, agents (scaffolds/ladders and weather conditions. The outcomes contributed to identifying the most significant research area for safety enhancement by improving engineering facilities, behaviour investigations and FFH prevention methods.

    2016-08-01

    Full Text Available Capacity expansion generally requires large capital expenditure on illiquid assets. Therefore, decisions to enlarge capacity must support the organisation’s strategic objectives and provide valuable input for the budgeting process. This paper applies an expanded form of Real Options Analysis (ROA to generate and evaluate capacity expansion strategies under uncertainty in the construction material industry. ROA is applied to different expansion strategies associated with different demand scenarios. Evaluating a wider variety of strategies can reduce risk and sponsor decisions that maximise the firm’s value. The case study shows that the execution of a lead expansion strategy with 10-year intervals under a 50 per cent demand satisfaction scenario produces superior results.

    Full Text Available Knowledge on and application of the legislation and professional reasoning in a professional manner related to control and situation in the field, of the control methods and procedures, is one of the essential premises that ensures efficiency and finality in the activity of patrimony control of an entity in the constructions field. A financial audit, which aims at an integrated control, provides conclusions on the entire activity. It fully characterizes the efforts and the results and it can also show faults, deficiencies and frauds in their entirety. The stocks cannot be simply taken into account as they are in a balance sheet and say straight away that the entity has sufficient stocks and it is performant. It is necessary to have a stock audit in order to highlight the accordance between the records and the physical stocks or their movement. The same reasoning also applies to outstanding debts, purchase/selling of real estate, rents of real estates, verification of contractual obligations, declarations regarding and actual payment of taxes to the state budget and the state social security budget etc. The relationship between audit and the benchmarking plan is given precisely by the final result of a performance evaluation and in order to get to a correct result it is necessary to have correct data and financial indicators. Otherwise, the risk is to evaluate an entity as performant and shortly after that it goes into bankruptcy. Benchmarking is a support instrument for decision-making, a continuous evaluation process, a mean of looking for the most performant methods to do a given activity. It is a system of information that allows an entity to show its development strategy, a technique for determining its competitive advantages and to learn about its products, services and operations by comparing them with the best ones. This instrument is part of the flexible management techniques that are based on learning, on initiative, together with ABM

    This study attempts to validate a safety performance (SP) measurement model in the cross-cultural setting of a developing country. In addition, it highlights the variations in investigating the relationship between safety climate (SC) factors and SP indicators. The data were collected from forty under-construction multi-storey building projects in Pakistan. Based on the results of exploratory factor analysis, a SP measurement model was hypothesized. It was tested and validated by conducting confirmatory factor analysis on calibration and validation sub-samples respectively. The study confirmed the significant positive impact of SC on safety compliance and safety participation, and negative impact on number of self-reported accidents/injuries. However, number of near-misses could not be retained in the final SP model because it attained a lower standardized path coefficient value. Moreover, instead of safety participation, safety compliance established a stronger impact on SP. The study uncovered safety enforcement and promotion as a novel SC factor, whereas safety rules and work practices was identified as the most neglected factor. The study contributed to the body of knowledge by unveiling the deviations in existing dimensions of SC and SP. The refined model is expected to concisely measure the SP in the Pakistani construction industry, however, caution must be exercised while generalizing the study results to other developing countries.

    Full Text Available After three decades of construction of a definition of Corporate Social esponsibility (CSR, in the eighties of last century they were included the prospects for voluntary action beyond the legal aspect and the theory of stakeholders. Although the debate about this topic has not finished, it has become usual that the company, even if free and private, must take into account its shareholders and stakeholders. In Colombia´s construction industry, considered vital to the economic and social development of the country, the discussion is only beginning. The concept of CSR in the construction industry is here presented, as well as how to make it possible through corporate practices and the precarious employment status of professionals and workers affected by such practices. These are developed in the framework of "liquid modernity", characterized by the economic emancipation of its traditional political, ethical and cultural ties.Después de tres décadas de construcción de una definición de Responsabilidad Social Empresarial (RSE, en los años ochenta del siglo pasado se incluyeron las perspectivas de la acción voluntaria más allá de lo legal y la teoría de los stakeholders o grupos de interés. Aunque el debate continúa al respecto, se hace general que la empresa, si bien libre y privada, debe tener en cuenta a sus accionistas y a los grupos de interés. En el sector de la construcción en Colombia, considerado de vital importancia para el desarrollo económico y social del país, la discusión es incipiente. Aquí se presenta el concepto de RSE en el sector de la construcción, la forma de materializarlo a través de prácticas empresariales y la precaria condición laboral de profesionales y obreros, afectada por dichas prácticas. Estas se desarrollan en el marco de la “modernidad líquida”, caracterizada por la emancipación de la economía de sus tradicionales ataduras políticas, éticas y culturales.

    Full Text Available The article highlights the obstacles in building the necessary amount of food and in ensuring the full import substitution based on the efficient use of the available resources: Russia’s lagging behind economically developed countries in the technical and technological modernization of agricultural sectors; low-rate processes of production intensification in the ongoing targeted programs; insufficient use of existing competitive advantages of individual regions. Consequently, in the current environment of increased competition between agricultural commodity producers of different countries, the mechanism of Russian agriculture state support needs to be improved. Based on the analysis of threats due to Russia’s entry into the WTO in terms of sanctions imposed by the European Union in relation to the events in Ukraine, the authors proposed and justified measures aimed at modernizing the mechanism of state regulation of regional agriculture of Russia in the new economic and social constructs. In order to develop a high-tech industrial chain in agricultural business, the authors have developed the mechanism of functioning production and logistics agrocenter organized to bring together competences and cooperation between enterprises in different industries. Agrocenter is a special investment area, which should be provided with all necessary infrastructure and professional management for subsequent placement on the same territory: commercial resident working in the agricultural sector; commercial residents working in the transport and warehouse complex; financial market enterprises and organizations for quality control and certification; consulting firms for the development and promotion agrocenter; consumers of agricultural products: manufacturing, wholesale and retail, commercial enterprises, social sphere.

    Production of residues from industries and construction and demolition sectors has increased during last years. The total amount of debris produced according to different estimations reaches values close to 42 million tonnes yr{sup -}1. Much of this waste has been thrown to landfill, without considering its potential for reuse, recycling or valuation. The aim of this research is to describe some of the physical and mechanical properties of different laboratory-mixed concretes, using various proportions of additional materials recovered from industrial waste and demolition rubble. The added materials are included either as admixtures (forestry residues, cork dust, steel fibre) or in partial substitution of natural aggregates (wire from electrical residues, tyre rubber, white ceramic, sanitary porcelain or shale). The laboratory tests have followed the standard EN protocols. Assay results were variable according to the nature of the material added to the mix: organic materials and shale, despite the steel fibre reinforcement, reduce the compression strength, but are suitable for the manufacture of lightweight concrete for agricultural pavements, with certain flexion resistance and a relatively good behaviour to impact. The substitution of natural aggregates with ceramic and porcelain wastes produces a significant increase in compression resistance, making them suitable for the manufacture of concrete with characteristic resistances above 40 MPa, which can be used both for structures or other agricultural elements: separators, feeders, slat floors. As a conclusion can be stated the possibility of reuse these wastes for the production of structural or non-structural concrete, with different applications in agricultural engineering.

    Industrial wastewater treatment comprises several processes to fulfill the discharge permits or to enable the reuse of wastewater. For tannery wastewater, constructed wetlands (CWs) may be an interesting treatment option. Two-stage series of horizontal subsurface flow CWs with Phragmites australis (UP series) and Typha latifolia (UT series) provided high removal of organics from tannery wastewater, up to 88% of biochemical oxygen demand (BOD(5)) (from an inlet of 420 to 1000 mg L(-1)) and 92% of chemical oxygen demand (COD) (from an inlet of 808 to 2449 mg L(-1)), and of other contaminants, such as nitrogen, operating at hydraulic retention times of 2, 5 and 7 days. No significant (P<0.05) differences in performance were found between both the series. Overall mass removals of up to 1294 kg COD ha(-1)d(-1) and 529 kg BOD(5)ha(-1)d(-1) were achieved for a loading ranging from 242 to 1925 kg COD ha(-1)d(-1) and from 126 to 900 kg BOD(5)ha(-1)d(-1). Plants were resilient to the conditions imposed, however P. australis exceeded T. latifolia in terms of propagation.

    This study aimed at determining the treatment performances of a full-scale vertical flow constructed wetlands designed to treat wastewater from a food-processing industry (cookie factory), and to study the influence of the organic loading rate. The full-scale treatment plant was designed with a first vertical stage of 630 m², a second vertical stage of 473 m² equipped with a recirculation system and followed by a final horizontal stage of 440 m². The plant was commissioned in 2011, and was operated at different loading rates during 16 months for the purpose of this study. Treatment performances were determined by 24 hour composite samples. The mean concentration of the raw effluent was 8,548 mg.L(-1) chemical oxygen demand (COD), 4,334 mg.L(-1) biochemical oxygen demand (BOD5), and 2,069 mg.L(-1) suspended solids (SS). Despite low nutrients content with a BOD5/N/P ratio of 100/1.8/0.5, lower than optimum for biological degradation (known as 100/5/1), mean removal performances were very high with 98% for COD, 99% for BOD5 and SS for the two vertical stages. The increasing of the organic load from 50 g.m(-2).d(-1) COD to 237 g.m(-2).d(-1) COD (on the first stage) did not affect removal performances. The mean quality of effluent reached French standards (COD < 125 mg.L(-1), BOD5 < 25 mg.L(-1), SS < 35 mg.L(-1)).

    Constructed wetlands are ecosystems that use plants and microorganisms to remediate pollution in soil and water. In this study, two parallel pilot-scale vertical flow wetland and horizontal flow wetland (VF-HF) systems were implemented to investigate the treatment performance and microorganism community structure in the secondary effluent of an industrial park wastewater treatment plant (WWTP) with a loading rate of 100 mm/day near the Yangtze River in Suzhou City, East China. Removal efficiencies of 82.3, 69.8, 77.8, and 32.3 were achieved by the VF-HF systems for ammonium nitrogen (NH4 (+)-N), total nitrogen (TN), total phosphorus (TP), and chemical oxygen demand (COD), respectively. The VF system specialized in COD and NH4 (+)-N removal (73.6 and 79.2 %), whereas the HF system mainly contributed to TN removal (63.5 %). The effluents in all seasons are capable of achieving the "surface water environmental quality standard" (GB3838-2002) grade IV. In the VF system, the 16S gene and nirK gene were significantly correlated with depth, with the 16S gene showing significant correlations with the dissolved oxygen (DO) level (r = 0.954, p < 0.05), which was determined by real-time PCR and high-throughput sequencing. Many types of bacteria capable of biodegradation, including nitrifiers, denitrifiers, and polyaromatic hydrocarbon (PAH) degraders (improvement of the BOD5/COD ratio), were observed, and they contributed to approximately 90 % of the nitrogen removal in the VF-HF system.

    The building construction industry, as broken down by the Bureau of Economic Analysis, U.S. Department of Commerce, was integrated into the Energy Input/Output Model developed at the Center for Advanced Computation, University of Illinois. The resulting expanded model was used to determine energy intensities of various (49) building construction (new and maintenance) sectors and of the overall building construction industry, for year 1967. The latter figure was computed at about 70,000 Btu/$, i.e., the construction industry on the average required about 70,000 Btu of direct and indirect energy per dollar of output produced. The most energy intensive sector was New Construction of Petroleum Pipelines (about 150,000 Btu/$), while the least intensive was Maintenance Construction for Electric Utilities (about 25,000 Btu/$). Also developed were total energy (direct and indirect) requirements to final demand for the building construction industry, for 1967. The overall industry required about 6000 trillion Btu, or about nine percent of the total U.S. energy requirement. New Highway Construction required the most energy to final demand (about 1000 trillion Btu, or 16 percent of the total construction industry requirement), while Maintenance Construction Residential required the least (about 9 trillion Btu, or 0.1 percent of the total industry requirement.

    Full Text Available This work aims at the development of a management model and programme for the Wine Museum of Alcobaça in dialectic articulation with a political strategy of cultural stimulation and local development. By using a deductive methodology, we bring forward a theorethical reflection on the revitalization and redefinition of the industrial tourism linked to viticulture. Having in mind the context of the historical events of the museum, which encompass the social, cultural and territorial context, the institutional genesis and the changing of the authority, the analythical body grows from the notions of enotourism and industrial tourism as differenciating and stimulating elements of a sustainable development. In that sense, the museum takes its role as instigator of a process of social and economic transformation that involves a set of discourses and practices towards a change.

  1. "Boom and bust" cycles in power plant construction: A simulation study of the temporal and geographical aspects of the Alberta competitive electrical industry

    Science.gov (United States)

    Seel, Kevin C.

    This dissertation describes a study undertaken to explore the potential for power plant construction to appear in the deregulated Alberta electrical system in waves of alternating under and over supply of electricity, or "boom and bust". The ultimate impact to the market in such a case would be major swings in wholesale electricity prices as the industry transitions through the phases of a construction cycle. The study begins by exploring a geographical perspective on electricity and energy in general. It then provides a brief historical context on electrical deregulation in Alberta and elsewhere, before discussing the relevant literature pertaining to simulating dynamic feedback within energy systems with a focus on electricity. The work makes extensive use of Forrester's (1961) System Dynamics methodology to construct a simulation model called "APPCON" (for Alberta Power Plant Construction model). APPCON was used to demonstrate the conditions under which "boom and bust" construction cycles might occur using an explicit theory of investor behavior. Construction cycles are a potentially serious problem but they are not inevitable. The research concludes with computer simulations demonstrating how construction cycles could be dampened or eliminated through two different policy mitigation strategies; (1) continuous capacity payment along side of the market clearing price for energy, and, (2) a conservation strategy based on price sensitive load curtailment.

    Limited trust, cooperation and communication have been identified as some of the issues that hinder collaboration among business partners. These one also true in the acceptance of e-supply chain integrator among organizations that involve in the same industry. On top of that, the huge number of components in supply chain industry also makes it impossible to include entire supply chain components in the integrator. Hence, this study intends to propose a method for identifying "trusted" collaborators for inclusion into an e-supply chain integrator. For the purpose of constructing and validating the method, the Malaysian construction industry is chosen as the case study due to its size and importance to the economy. This paper puts forward the background of the research, some relevant literatures which lead to trust values elements formulation, data collection from Malaysian Construction Supply Chain and a glimpse of the proposed method for trusted partner selection. Future work is also presented to highlight the next step of this research.

    Full Text Available Industrialised Building System (IBS contributes a great shift in sustainable construction and benefits the society. Previous studies have proven in general that one of the hindrances in promoting sustainable in IBS, is a high cost for any pre-cast material specifically thus effected the overall cost. The introduction of Life Cycle Costing (LCC leads into providing a better and comprehensive cost estimation, including projecting actual cost to operate the building, hence providing a better baseline for decision making. The lacking application of LCC in IBS is still in trivial impact, therefore, this paper presents a framework which produced by expressing the successful initiatives of LCC and IBS in Malaysia construction industry. The framework developed based on findings from the extensive literature reviews, 164 responded questionnaires, and 19 expert opinions, which has three sections: Strategy Development, System Development and the last part is Decision Level. Aspects of objectivity, practicality, reliability, completeness that were likely to be implemented in the Malaysian construction industry were used. There are significant opinions on the usefulness and completeness of the proposed framework in providing a comprehensive cost estimates which helps much in deciding to carry out IBS or remain with a traditional construction method.

    The global construction sector is experiencing major improvements to building materials used in large quantities through commercial applications of nanotechnology. Nano-enabled construction products hold great promise for energy efficiency and resource conservation, but risk assessments lag as new products emerge. This paper presents results from an inventory, survey, and exposure assessment conducted by the authors and explores these findings in the broader context of evolving research trends and responsible development of nanotechnology. An inventory of 458 reportedly nano-enabled construction products provided insight into product availability, potential exposures, and deficiencies in risk communication that are barriers to adoption of proactive safety measures. Seasoned construction trainers surveyed were largely unaware of the availability of nano-enabled construction products. Exposure assessment demonstrated the effectiveness of ventilation to reduce exposures during mechanical abrasion of photocatalytic tiles containing titanium dioxide (TiO{sub 2}). Dissociated particles of TiO{sub 2} just above the nanoscale (138 nm) were detected in the debris collected during cutting of the tiles, but measurements were below recommended exposure limits for TiO{sub 2}. Exposure assessments remain scarce, and toxicological understanding primarily pertains to unincorporated nanomaterials; less is known about the occupational risks of nano-enabled construction products across their life cycle. Further research is needed to characterize and quantify exposure to debris released from nanocomposite materials for realistic risk assessment, and to ascertain how nanocomposite matrices, fillers, and degradation forces interact to affect release dynamics. Improving risk communication strategies and implementing safe work practices will cultivate responsible development of nanotechnology in construction, as will multidisciplinary research efforts.

  13. GHG mitigation in the construction industry – analysis of the efficiency of legislation in Rio de Janeiro

    2012-07-01

    Full Text Available In the year of 2007 a Protocol of Intentions was organized to set up mitigation engagement for the global warming effects in the municipality of Rio de Janeiro in 2007. However, targets for reducing emissions of greenhouse gases (GHG were only established in 2009 through the "Sustainable Rio Program”. One of the actions set out under the Protocol and the Program is the legal determination of the compensation of GHG emissions by the civil construction sector, through planting trees. This article examines the evolution of this legal framework and investigates the effectiveness of Law 613/84 and Decree 31.180/09, under the environmental point of view, in relation to the dynamics of CO2.These legal instruments determine planting trees by the civil construction sector, in an amount calculated based on the total area of construction. The analysis was focused on the period from January to July 2010, which corresponds to the first semester after legal determination of the compensation of GHG emissions by the civil construction sector through planting trees. In the analysis we compared the estimates of emissions by new constructions licensed by the City Hall in the first six months of institutionalization of the emissions offsetting scheme and the estimate of total carbon to be sequestered by planting trees, legally required in the licensing of buildings. This analysis shows that current legislation is ineffective in offsetting the emissions generated in licensed buildings in the city of Rio de Janeiro, through planting of trees.

    Full Text Available A survey of women in the Australian construction industrywas undertaken to examine women's work experiencesin construction. Questionnaires were distributed to threehundred women in construction occupations and 109completed and usable questionnaires were returned.Women were found to be seriously under-represented insite-based roles. Site/project engineers worked longer hoursthan other occupational groups and expressed significantlygreater work-family conflict. Lack of flexibility and theinability to balance work and family were common themesin the qualitative comments made by many respondents.Even when women indicated that part time work options andmaternity entitlements were provided by their organizations,many expressed a reluctance to use them and perceivedcareer penalty associated with this usage. It is concludedthat more flexible work schedules and the implementationof family-friendly policies may encourage more women intosite-based roles in construction. The paper concludes thatthe rigid work practices presently in place act as a subtleform of discrimination. The provision of such policies willonly be effective if cultural and attitudinal change is alsoachieved.

    2014-04-01

    Existing heat stress risk management guidelines recommended by international standards are not practical for the construction industry which needs site supervision staff to make instant managerial decisions to mitigate heat risks. The ability of the predicted heat strain (PHS) model [ISO 7933 (2004). Ergonomics of the thermal environment analytical determination and interpretation of heat stress using calculation of the predicted heat strain. Geneva: International Standard Organisation] to predict maximum allowable exposure time (D lim) has now enabled development of localized, action-triggering and threshold-based guidelines for implementation by lay frontline staff on construction sites. This article presents a protocol for development of two heat stress management tools by applying the PHS model to its full potential. One of the tools is developed to facilitate managerial decisions on an optimized work-rest regimen for paced work. The other tool is developed to enable workers' self-regulation during self-paced work.

    1998-12-01

    Several ferrous and non ferrous metallurgical wastes, slag, powdered wastes, alkaline liquors, etc., can be used as binding materials to produce new building materials. These materials can be used in place of concretes made of cement, crushed stones, sand and gravel mixtures in several applications, road, industrial and airport foundations, etc. They are leaching resistant, so heavy metals do not migrate to the environment. These new materials, with a new structure, are obtained by mixing in right proportion of two or three industrial wastes or with mixtures of two of them and natural soils without any addition of traditional binders like and without heating. The main advantages are the solution of the problem of disposal of industrial wastes and the lower cost of the new materials, 5 to 6 times cheaper than traditional. Several examples of roads existing in Russia, even in Siberia and other northern regions, demonstrate the benefit of this process because after 20 years they still offer a good performance.
