    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.

    Full Text Available This study was undertaken to identify key stress factors among professionals in building construction industry in Nigeria. This is in view of the fact that to date, very little is known about work stress among professionals in building construction industry in this country. The study involved the administration of questionnaire to 107 professionals including architects, builders, civil/structural engineers and quantity surveyors randomly selected from 60 ongoing building projects in Anambra, Ogun and Kaduna States, Nigeria. The data was analysed using descriptive statistics, and findings show that the principal sources of stress were high volume of work, uncomfortable site office environment, lack of feedback on previous and ongoing building projects, and variations in the scope of work in ongoing building projects. The paper suggests that taking responsibility for work which one has adequate capacity to handle, establishing realistic budgets and time frame for project delivery, provision of spatially adequate, visually and thermally comfortable site offices, adoption of appropriate job design practice and education of professionals on stress management strategies will reduce the incidence of stress among professionals in building industry in Nigeria.

    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.

    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.

    2001-07-01

    The principal sectors of the Canadian construction industry - commercial, industrial, institutional and residential - are examined with regard to their technical considerations concerning the subject of sustainability. Apart from the different needs of each of the sectors of the industry there are also regional differences caused by population distribution, and differences in climate, that have to be identified and accommodated in considering attitudes to recycling and sustainable development. Some indications that there is growing awareness of recycling and reuse are: the increasing frequency of life cycle costing in the commercial and institutional sectors, the use of recycled or otherwise waste materials in concrete, examples of using steel supporting structures and roof joists salvaged from previous uncompleted projects in the industrial sector, improved building envelope and indoor air quality concerns, collective ground source heating, and new basement and framing technologies and construction materials in the residential sector. These improvements notwithstanding, there remains much to be done. The new objective-based National Building Code, for which comments are now being solicited across the country, is expected to identify new and innovative solutions and to kick-start serious efforts to come up with solutions towards increasing overall sustainability in all sectors of the Canadian construction industry.

    The construction industry accounts for over 11.14% of the total energy consumed in the US annually. This represents the equivalent energy value of 1 1/4 billion barrels of oil. Within the construction industry, new building construction accounts for 5.19% of national annual energy consumption. The remaining 5.95% is distributed among new nonbuilding construction (highways, ralroads, dams, bridges, etc.), building maintenance construction, and nonbuilding maintenance construction. The handbook focuses on new building construction; however, some information for the other parts of the construction industry is also included. The handbook provides building designers with information to determine the energy required for buildings construction and evaluates the energy required for alternative materials, assemblies, and methods. The handbook is also applicable to large-scale planning and policy determination in that it provides the means to estimate the energy required to carry out major building programs.

    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.

We shall call the mathematical calculation models for the parameters-reasons of destructions the basic models. The basic models of destruction of building structures elements allow not only providing necessary level of reliability and survivability of the elements and the construction as a whole already at the stage of their design, but also giving the chance, at their corresponding completion, to provide rational decisions on the general need of recovery works and their volume depending on destruction level. Especially important for rational design decisions development, which ensure the demanded constructional safety of building structures, is library creation of the basic mathematical models of standard processes of bearing elements destructions for standard construction designs for the purpose of the further forecast (assessment of the level and probabilities of standard destructions. Some basic mathematical models of destructions processes of the standard elements of building structures are presented in the present article. A model of accounting for construction defects and a model of obtaining requirements to probabilities of partial destructions of a construction are given. Both of these models are probabilistic.

    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

    This investigation explores the possibility of utilizing granular slag as an alternative to fine aggregate (natural sand) in construction applications like masonry and plastering. Construction industry utilizes large volume of fine aggregate in all the applications which has resulted into shortage of good quality naturally available fine aggregate. Use of granular slag serves two fold purposes, i.e. waste utilisation as well as alternative eco-friendly green building material for construction. The investigation highlights comparative study of properties with partial and full replacement of fine aggregate (natural sand) by granular slag in cement mortar applications (masonry and plastering). For this purpose, cement mortar mix proportions from 1:3, 1:4, 1:5 & 1:6 by volume were selected for 0, 25, 50, 75 & 100% replacement levels with w/c ratios of 0.60, 0.65, 0.70 & 0.72 respectively. Based on the study results, it could be inferred that replacement of natural sand with granular slag from 25 to 75% increased the packing density of mortar which resulted into reduced w/c ratio, increased strength properties of all mortar mixes. Hence, it could be recommended that the granular slag could be effectively utilized as fine aggregate in masonry and plastering applications in place of conventional cement mortar mixes using natural sand.

    Full Text Available Better construction and use of buildings in the European Union would influence 42% of final energy consumption, about 35% of our greenhouse gas emissions and more than 50% of all extracted materials. It could also help to save up to 30% of water consumption. This paper outlines and draws conclusions about different aspects of the material efficiency of buildings and assesses the significance of different building materials on the material efficiency. The research uses an extensive literature study and a case-study in order to assess: should the depletion of materials be ignored in the environmental or sustainability assessment of buildings, are the related effects on land use, energy use and/or harmful emissions significant, should related indicators (such as GHGs be used to indicate the material efficiency of buildings, and what is the significance of scarce materials, compared to the use of other building materials. This research suggests that the material efficiency should focus on the significant global impacts of material efficiency; not on the individual factors of it. At present global warming and greenhouse gas emissions are among the biggest global problems on which material efficiency has a direct impact on. Therefore, this paper suggests that greenhouse gas emissions could be used as an indicator for material efficiency in building.

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 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.

    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.

    A complete construction set of building blocks usually comes with instructions and these instruction include building stages. The products of these building stages usually build from very general parts become highly specialized building parts for very unique features of the whole construction model. This sounds very much like the construction or organization of an interdisciplinary research project, institution or association, doesn't it! The creation process of an overarching data policy for a project group or institution is exactly the combination of individual interests with the common goal of a collaborative data policy and can be compared with the building stages of a construction set of building blocks and the building instructions. Keeping this in mind we created the data policy construction set of textual building blocks. This construction set is subdivided into several building stages or parts each containing multiple building blocks as text blocks. By combining building blocks of all subdivisions it is supposed to create a cascading data policy document. Cascading from the top level as a construction set provider for all further down existing levels such as project, themes, work packages or Universities, faculties, institutes down to the working level of working groups. The working groups are picking from the remaining building blocks in the provided construction set the suitable blocks for its working procedures to create a very specific policy from the available construction set provided by the top level community. Nevertheless, if a working group realized that there are missing building blocks or worse that there are missing building parts, then they have the chance to add the missing pieces to the construction set of direct an future use. This cascading approach enables project or institution wide application of the encoded rules from the textual level on access to data storage infrastructure. This structured approach is flexible enough to allow for

    This final report summarizes the work conducted by the Building America Industrialized Housing Partnership (www.baihp.org) for the period 9/1/99-6/30/06. BAIHP is led by the Florida Solar Energy Center of the University of Central Florida and focuses on factory built housing. In partnership with over 50 factory and site builders, work was performed in two main areas--research and technical assistance. In the research area--through site visits in over 75 problem homes, we discovered the prime causes of moisture problems in some manufactured homes and our industry partners adopted our solutions to nearly eliminate this vexing problem. Through testing conducted in over two dozen housing factories of six factory builders we documented the value of leak free duct design and construction which was embraced by our industry partners and implemented in all the thousands of homes they built. Through laboratory test facilities and measurements in real homes we documented the merits of 'cool roof' technologies and developed an innovative night sky radiative cooling concept currently being tested. We patented an energy efficient condenser fan design, documented energy efficient home retrofit strategies after hurricane damage, developed improved specifications for federal procurement for future temporary housing, compared the Building America benchmark to HERS Index and IECC 2006, developed a toolkit for improving the accuracy and speed of benchmark calculations, monitored the field performance of over a dozen prototype homes and initiated research on the effectiveness of occupancy feedback in reducing household energy use. In the technical assistance area we provided systems engineering analysis, conducted training, testing and commissioning that have resulted in over 128,000 factory built and over 5,000 site built homes which are saving their owners over $17,000,000 annually in energy bills. These include homes built by Palm Harbor Homes, Fleetwood, Southern Energy

    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 The construction industry is known as one of the most hazardous activities. Therefore, safety on the job site is an important aspect with respect to the overall safety in construction. This paper assesses the safety level perception of the construction building workers towards safety, health and environment on a construction job site in Kuala Lumpur, Malaysia. The above study was carried out by choosing 5 selected large building construction projects and 5 small building construction projects respectively in and around Kuala Lumpur area. In the present study, an exhaustive survey was carried out in these 10 project site areas using a standard checklist and a detailed developed questionnaire. The checklist comprised 17 divisions of safety measurements which are considered and perceived to be important from the safety point of view and was assessed based on the score obtained. The questionnaire comprised the general information with 36 safety attitude statements on a 1-5 Likert scale which was distributed to 100 construction workers. The results of the checklist show the difference of safety levels between the large and small projects. The study revealed that the large projects shown a high and consistent level in safety while the small projects shown a low and varied safety levels. The relationship between the factors can be obtained from the questionnaire. They are organizational commitment, factor influencing communication among workmates, worker related factors, personal role and supervisors’ role factors, obstacles to safety and safe behavior factors and management commitment at all levels in line with the management structure and risk taking behavioral factors.

    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 In Malaysian construction industry, problem is a common occurrence that hinders the project to run smoothly, notably in traditional contracting system where the design and construction process are separated. Previous research revealed that buildability is able to minimise these problems as it link the design and construction. This study outlines the buildability in design stage. Extensive reviews have been carried out on previous researches on buildability concepts, attributes, principles and other areas related to, and contributing to buildability mainly in the design phase. The term ‘buildability attribute’ has been selected in this study to describe those characteristics which directly or indirectly optimize integration of construction knowledge in the building process and balancing the various project and environment constraints to maximize project goals and building performance. Close examinations of available references revealed that altogether there are 19 buildability attributes that can be implemented during the design phase. The results of survey show that Malaysian construction industry practitioners rate the attribute Provide Clear and Complete Design Information (4.56 as the most important and Less Work Below Ground (3.60 as the least important attribute. The client, consultant and contractor share the same opinion regarding the most important and least important attributes, only higher instituiton’s view is slightly different. Out of 19 attributes, 11 attributes have mean values above 4.00, which indicate them as important attributes. This study has successfully measure the importance level of design buildability attributes for building construction in Malaysia.

    The safety analysis of reinforced concrete buildings during construction should be based on the comprehensive understanding of loads, load effects, structural resistance, and available safety index of the structure. This paper analyzes the characteristics and probabilistic models of resistance, loads, and load effects. A method was developed to calculate the probability of failure based on Monte Carlo simulation and models proposed in previous articles. Construction examples were used to analyze the influence of live load on the probability of failure. The results show that when the live load increases, the maximum probability of failure increases with acceleration. The results suggest that the construction live load should be carefully addressed during construction.

    The US construction industry annually experiences a relatively high rate of fatalities and injuries; therefore, improving safety practices should be considered a top priority for this industry. Modular/prefabricated building construction is a construction strategy that involves manufacturing of the whole building or some of its components off-site. This research focuses on the safety performance of the modular/prefabricated building construction sector during both manufacturing and on-site processes. This safety evaluation can serve as the starting point for improving the safety performance of this sector. Research was conducted based on Occupational Safety and Health Administration investigated accidents. The study found 125 accidents related to modular/prefabricated building construction. The details of each accident were closely examined to identify the types of injury and underlying causes. Out of 125 accidents, there were 48 fatalities (38.4%), 63 hospitalized injuries (50.4%), and 14 non-hospitalized injuries (11.2%). It was found that, the most common type of injury in modular/prefabricated construction was 'fracture', and the most common cause of accidents was 'fall'. The most frequent cause of cause (underlying and root cause) was 'unstable structure'. In this research, the accidents were also examined in terms of corresponding location, occupation, equipment as well as activities during which the accidents occurred. For improving safety records of the modular/prefabricated construction sector, this study recommends that future research be conducted on stabilizing structures during their lifting, storing, and permanent installation, securing fall protection systems during on-site assembly of components while working from heights, and developing training programmes and standards focused on modular/prefabricated construction.

    2014-05-01

    It is often predicted that the industrialization of building activities will lead to a reduction of accident rates in the construction sector, particularly as a result of switching activities from building sites to factories. However, to date no scientific research has provided objective quantitative results to back up this claim. The aim of this paper is to evaluate how industrialization affects the accident rate in different industrialized building systems in Spain. Our results revealed that the industrialized steel modular system presents the lowest accident rate, while the highest accident rate was recorded in the construction method with cast-in-place concrete. The lightweight construction system also presents a high accident rate. Accordingly, industrialized building systems cannot claim to be safer than traditional ones. The different types of "on-site work" seem to be the main variable which would explain the accident rates recorded in industrialized construction systems.

  7. Evaluation of Karst Hazards for Civil and Industrial Buildings

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The European part of Russia exhibits highly developed sulphate and carbonate karst. It mostly occurs within fiver valleys with relatively thin coveting deposits. These conditions may induce karst collapses, which appear to be the main danger for civil and industrial buildings. Evolution of karst rocks includes several epochs of karst development,which causes complicated distribution of karst caves in karst rocks and, as the result, irregular distribution of karst caves on the surface. Karst hazards prediction is mostly reliable within the geotechnical system "Karst-Construction", using probability methods. This approach allows creating 3 types of antikarst protection (alternative design of construction arrangement on a plan, structural protection of a construction and plugging of karst caves beneath construction foundation) and selecting the optimum or the most effective version or their rational combination.``

    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.

    Full Text Available This paper discusses theory and application of microwave radiation and experimental optimization of microwave radiation to eliminate moisture content in wood elements. It will be appreciated that the rising moisture leaking into the structure, resulting in defects and structures of the buildings themselves. Owing to its properties, microwave radiation has been used in the construction industry in modern times, in particular to dry wet masonry of buildings. Effects of electromagnetic radiation on building structures lead to relatively sharp decreases in moisture content from damp building structures or elements. The influence of electromagnetic radiation on building structures lead to oscillation of water molecules contained in the material, which cause a phase transformation of water into vapour. Consequently, the vapour evaporates from the moist material, thereby drying the element exposed to radiation. The article describes experiments carried out at the Faculty of Civil Engineering of the Faculty of Technology in Brno that demonstrate successful decrease of water content in building materials using microwave radiation. First, the understanding of microwave radiation will be discussed. Following an analysis of research results an optimum intensity of microwave radiation sources as well as the necessary length of the irradiation of microwave radiation have been determined with respect to the particular type of building material and the success rate of elimination of moisture.

    Full Text Available This study is conducted to compare between the two approaches of construction. It is carried out through case studies on construction sites, distribution of a total of 100 questionnaires as well as interviewing respondents who are related to this discourse. The case studies for this research were carried out at four construction sites within the Malaysian state of Penang. Two case studies used Industrialised Building System method while the remaining two deployed the traditional method of construction. Based on the analysis of obtained results, it can be surmised that the Industrialised Building System approach has more to offer compared to the traditional method. Among these advantages are; reduced construction durations, reduced overall cost, reduced labour requirements, better site conditions and the production of components of higher quality among others. This study also managed to determine the perceptions of key players in the industry and their rationales in preferring the traditional approach while at the same time, admitting to the edges offered by the Industrialised Building System.

    This paper reviews the literature concerning the energy saving and outlines the importance of energy efficiency, particularly in three the most important areas: buildings, industry and transportation. Improving energy efficiency plays a crucial role in minimizing the societal and environmental impacts of economic growth and offers a powerful tool for achieving sustainable development by reducing the need for investment in new infrastructure, by cutting fuel costs, and by increasing competitiveness for businesses and welfare for consumers. It creates environmental benefits through reduced emissions of greenhouse gases and local air pollutants. It can offer social benefits in the form of increased energy security (through reduced dependence on fossil fuels, particularly when imported) and better energy services.

    1976-12-01

    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 49 building and non-building construction sectors (new and maintenance). Total energy intensities were determined for these sectors, as well as energy requirements to final demand. Overall, the construction industry required about 6000 trillion Btu, or about 9% of the total U. S. energy requirement in 1967. About 20% of this requirement was for direct energy. Energy requirements were further broken down according to goods and services purchased by individual construction sectors, and energy distribution patterns were determined within each construction sector. Energy cost per unit for various building materials were calculated, as well as 1967 energy cost per square foot for building sectors. Laboratories required the most energy per square foot (2,074,056 Btu/SF), while Farm Service required the least (149,071 Btu/SF). Comparative interchangeable building assemblies were evaluated for their energy costs, including initial construction and lifetime maintenance energy. Tradeoffs between construction and operational energy costs were determined for a selected wall frame assembly with different exterior finishes and varying degrees of insulation. A study was initiated to determine industries in which direct energy use led to a significant amount of the energy embodied in New Building Construction for 1967. The resulting Energy Flow Chart is included.

    Full Text Available Problem statement: Building insulation consisting roughly to anything in a structure that is utilizes as insulation for any reason. Thermal insulation in structures is a significant feature to attaining thermal comfort for its tenants. Approach: Insulation decreases unnecessary warmth loss or gain and can reduce the power burdens of heating and cooling structures. It does not automatically having anything to do with problems of sufficient exposure to air and might or might not influence the amount of sound insulation. Results: In a constricted way insulation can just mean the insulation substance used to reduce heat loss, such as: Glass wool, cellulose, polystyrene, rock wool, urethane foam, vermiculite and the earth, but it can also entail a variety of plans and methods used to deal with the chief forms of heat movement like transmission, emission and convection substances. The efficiency of insulation is normally assessed by its R-value. However, an R-value does not allow for the superiority of assembly or narrow green issues for each structure. Building superiority matters comprise insufficient vapor obstructions and troubles with draft-proofing. Additionally, the property and concentration of the insulation substance itself is vital. Fiberglass insulation materials, for example, made out of short fibers of glass covered on top of each other is not as long-lasting as insulation prepared from extended entwined fibers of glass. Conclusion/Recommendations: Rockwool insulation is a kind of insulation that is constructed out of real rocks and minerals. It furthermore is known by the names of mineral wool insulation, stone wool insulation or slag wool insulation. A broad collection of goods can be constructed from Rockwool, because of its outstanding capability to obstruct sound and heat. Rockwool insulation is normally utilized in building assembly, manufacturing plants and in automotive purposes. In this study i proposed to use

    Full Text Available Problem statement: In the Malaysian construction industry, there is a pressing issue of minimizing construction waste, which cause significant impacts on the environment. With the increasing demand for major infrastructure projects, commercial buildings and housing development programmers, a large amount of construction waste is being produced. Adoption of prefabrication and industrialized building systems is now a priority in the industry and also an important means of reducing waste. Approach: Discussion of the prefabrication adoption were based on a comprehensive review of literatures and studies that contained data, information, findings and evidences related to prefabrication and industrial building systems in Malaysia. This study also highlighted a comparative study of material wastage and recycling based on two project sites e.g., conventional and prefabrication construction. Results: In the Malaysia construction industry, adoption of prefabrication and IBS is strongly encouraged to reduce construction time as well as the industry’s dependency on foreign workers. In addition, this study confirms that a huge amount of material wastage can be reduced by the adoption of prefabrication. This study also revealed that the rates of reused and recycled waste materials are relatively higher in projects that adopt prefabrication. Conclusion: Thus, the adoption of prefabrication and IBS has potential in the reduction of huge waste generation and management problems in the construction sector of Malaysia although there are some challenges in the adoption of prefabrication.

    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.

    A better understanding of general hindrances to the diffusion of innovations in the construction sector may help to improve the energy efficiency of buildings. This study uses a web-based questionnaire to collect information on Swedish architects' perceptions of hindrances to the adoption of innovations in building construction. The responding architects characterise the Swedish construction industry as having a low level of innovativeness. The most influential hindrances to innovativeness were perceived as the focus on project costs instead of life-cycle costs, the economic risks that innovations imply, the focus on traditional engineering models, the construction industry's tendency to use proven materials and methods, and contractors' inability to adjust processes. In terms of the involved actors, construction clients were perceived to have the greatest influence on innovativeness, and stronger cooperation between the architect and construction client was recognised as important to facilitate innovativeness

  2. A Conceptual Framework for Managing Design Changes in Building Construction

    2016-01-01

    Full Text Available Design changes have always been an innate feature of the construction industry. Despite the various project management techniques, many building construction projects still fail to achieve their time and cost objectives. This paper aims to focus on design changes as a major cause of time delays and cost overruns. It seeks to discuss the causing factors of design changes in building construction projects and highlighting the resulting rework that is detrimental to project performance. Hence, this paper also aims to present a conceptual framework which was developed to better manage design changes through clued-up management decision to avoid future claims and disputes. Recent and current literature is examined and reviewed. The review approach was based on related literature to identified themes. The existing literature is summarised into five discrete themes of “design changes”, “rework”, “time and cost overruns”, “communication” and “decision-making”. The synthesised literature is subsequently utilised in the development of conceptual map which provided the direction for designing the conceptual framework. Extensive review of preceding studies on causes of time and cost overruns reveals that design changes is identified as one of the significant factors. However, there are limited studies in this domain. The discussion presents a knowledge gap of linking design changes and rework with decision-making in project management. This finding suggests the need for further empirical study. The framework stresses the importance of communication and management decision as the control mechanism. Researchers and practitioners in construction management field will find this study useful in understanding the causing factors of design changes and its detrimental impacts to project performance which risk the project to claims and disputes. The conceptual framework presents an imperative outcome to encourage further research in developing

    California has a large number of small and medium sized industries which have a major impact on the demand growth of California utilities. Energy use in building services (lighting, HVAC, office equipment, computers, etc.). These industries constitute an important but largely neglected fraction of the total site energy use. The ratio of energy use in building service to the total site energy use is a function of the industrial activity, its size, and the climate at the site of the facility. Also, energy use in building services is more responsive to weather and occupant schedules than the traditional base-load'' industrial process energy. Industrial energy use is considered as a base-load'' by utility companies because it helps to increase the utilities' load factor. To increase this further, utilities often market energy at lower rates to industrial facilities. Presently, the energy use in the building services of the industrial sector is often clubbed together with industrial process load. Data on non-process industrial energy use are not readily available in the literature. In cases where the major portion of the energy is used in the building services (with daily and seasonal load profiles that in fact peak at the same time as systemwide load peaks), the utility may be selling below cost at peak power times. These cases frequently happen with electric utilities. 30 figs., 6 tabs.

    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.

  8. 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.

    Sustainability of buildings is a really important issue for the construction industry. Sustainable buildings are characterized by the lower construction costs for energy consumption and operations, they are environmentally friendly, able to save natural resources and they are comfortable and healthy for their users. The European Union supports this trend through its Strategy 2020, respectively with document Energy Roadmap 2020. The strategy 2020 sets greenhouse gas emissions 20% lower than 1990, 20% of energy from renewable and 20% increase in energy efficiency. It manifests itself in introduction of modern technologies of house building. One potential for the energy saving is construction of low-energy buildings using modern materials. This paper focuses on the analysis of the low-energy buildings made by expanded polystyrene as the bearing building material. The paper analyzes their design and describes the benefits of this modern but unusual type of construction technology for houses. The examples from abroad clearly indicate that this technology has potential in modern architecture. The success and exploration of this technology potential in the conditions of Slovak construction sector is closely related to interest of investors and users of further sustainable houses which are design according the Strategy 2020 conditions.

  8. Challenges of the expansive use of Building Information Modeling (BIM in construction projects

    Directory of Open Access Journals (Sweden)

    Hannele Kerosuo

    2015-06-01

    Full Text Available Building information modeling (BIM is an emerging modeling technology which challenges existing work procedures and practices in the construction industry. In this article we study the challenges, problems and potential expansions of BIM as a tool in the design, construction and operation of buildings. For this purpose the interfaces between different parties are examined in Finnish construction projects. The methodological approach of the study is cultural-historical activity theory, according to which a new artifact becomes a mediating instrument when the participatory subjects reconfigure the entire activity. The implementation of BIM is now spreading from the design activity to other phases of the construction projects, but its use is still limited in the projects' other three interfaces. BIM is an evolving set of software developed for various purposes which is locally 'combined' to fit the circumstances and capabilities of the stakeholders of the construction process.

    Ai-Lin Teo

    2012-11-01

    Full Text Available This paper deals with different aspects of differentiation as a strategy to maintain growth and profitability in a rapidly changing environment. The specific aim of the study was to establish constraints in the use of product differentiation as a survivor technique in the building industry. The study shows that firms in the building industry perceive the structure and operation of different markets in the building industry as substantially different. If firms are to improve their market positions by differentiating their output, they need therefore to adjust the way they operate, their resources and their skills base.The survey result also showed that a substantial proportion of all firms are not prepared to be involved in diversification but elect to operate in one market only, despite the obvious advantages of diversification. It would therefore seem likely that the changes in the way a firm operates and the resources it employs when it moves into new markets are substantial.

    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.

    2010-05-01

    Building Information Modeling (BIM) approach is increasingly adopted in coordination of construction projects, with a number of parties providing BIM services and software solutions. However, the empirical impact of BIM on construction industry has yet to be investigated. This paper explores the interaction between BIM and the construction industry during its implementation, with a specific focus on the empirical impacts of BIM on the design and construction processes and professional roles during the process. Two cases were selected from recent construction projects coordinated with BIM systems: the Venetian Casino project in Macau and the Cathy Pacific Cargo Terminal project in Hong Kong. The former case illustrates how the conflicts emerged during the design process and procurement were addressed by adopting a BIM approach. The latter demonstrates how the adoption of BIM altered the roles of architect, contractor, and sub-contractors involved in the project. The impacts of BIM were critically reviewed and discussed.

  14. Innovation Barriers and Enablers that Affect Productivity in Uganda Building Industry

    2007-06-01

    Full Text Available The construction industry has of recent been blamed for lack of innovation. Lack of innovation in the industry is believed to be responsible for the decreasing or stagnant levels of productivity in comparison with other industries. This paper reviews the major barriers and enablers to innovation in general. Propositions were made about the factors that affect innovation in the construction industry which were then formulated into a questionnaire. A survey was made on building contractors in Uganda, a developing country, targeting those with financial strength, large in size, and with high capacity to carry out big projects. The identified factors were then ranked and correlated. The level of training in science, engineering and technical education, and the level of research and development at the industry level are looked at as the greatest innovation enablers in building that will drive forward labour productivity. The size of the domestic market and the level of security are the worst innovation barriers that lead to low productivity in the building industry in Uganda. Contractors, policy makers and the government should address the identified factors in order to improve productivity.

    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.

    Kivi, P; Mattila, M

    1991-02-01

    Awkward work posture is associated with the development of musculo-skeletal disorders. Previous workplace investigations in new building construction have shown that physical work affects workers' health in 46% of jobs. There is, however, a need for detailed analysis of jobs having physical workload and ergonomics problems. OWAS (Ovako Working Posture Analysing System) is a simple observation method for postural analysis, but there has been no study of its use in the building construction industry. The work described here examined (a) the use of the OWAS method to analyse work postures in building construction, (b) the development of a portable computer system for the OWAS method, (c) improvement of work postures identified as poor, and (d) use of the results as part of the ergonomics training programme of the company. Suggestions for work redesign measures are given.

    Jaillon, L; Poon, C S; Chiang, Y H

    2009-01-01

    As Hong Kong is a compact city with limited available land and high land prices, the construction of high-rise buildings is prevalent. The construction industry produces a significant amount of building waste. In 2005, about 21.5 million tonnes of construction waste were generated, of which 11% was disposed of in landfills and 89% in public filling areas. At the present rate, Hong Kong will run out of both public filling areas and landfill space within the next decade. The government is taking action to tackle the problem, such as by introducing a construction waste landfill charge, and promoting prefabrication to reduce on-site waste generation. This paper reports an ongoing study on the use of prefabrication in buildings and its impact on waste reduction in Hong Kong. A questionnaire survey was administered to experienced professionals, and case studies of recently completed building projects were conducted. The results revealed that construction waste reduction is one of the major benefits when using prefabrication compared with conventional construction. The average wastage reduction level was about 52%. This implies that a wider use of prefabrication could considerably reduce construction waste generation in Hong Kong and alleviate the burdens associated with its management.

    Small buildings have been left behind in the energy efficiency marketplace because financial and technical resources have flowed to larger commercial buildings. DOE's Building Technologies Office works with the commercial building industry to accelerate the uptake of energy efficiency technologies and techniques in existing and new commercial buildings (DOE 2013). BTO recognizes the SBSP sector'spotential for significant energy savings and the need for investments in resources that are tailored to this sector's unique needs. The industry research and recommendations described in this report identify potential approaches and strategic priorities that BTO could explore over the next 3-5 years that will support the implementation of high-potential energy efficiency opportunities for thisimportant sector. DOE is uniquely positioned to provide national leadership, objective information, and innovative tools, technologies, and services to support cost-effective energy savings in the fragmented and complex SBSP sector. Properly deployed, the DOE effort could enhance and complement current energy efficiency approaches. Small portfolios are loosely and qualitatively defined asportfolios of buildings that include only a small number of small buildings. This distinction is important because the report targets portfolio owners and managers who generally do not have staff and other resources to track energy use and pursue energy efficiency solutions.

    Full Text Available Sustainable economic development of the construction industry in Russia is only possible with the application of modern BIM-technologies. The construction enterprises are facing a number of problems during the process of implementing new information technologies the main problems being: the lack of funding for business development under the conditions of protracted financial crisis within 2014-2016 time frame, as well as the lack of a national industry standard of working with BIM-technologies. The step-by-step introduction of BIM- technology in Russia is planned by the Government for the period up to 2018. We offer an economic mechanism of lower production and transaction costs of development as a result of the BIM-technology introduction, taking into account successful experience in the regional economy of the Republic of Tatarstan. In our opinion the practically well-proven mechanism of introduction of innovative technologies in regional economy in public construction companies, constructing infrastructure projects, and private construction firms and approbation in practice and summarizing the lessons learned will enable one to develop building information modeling services market and ensure the sustainable economic development of the construction industry in the region. The improvement of the efficiency and transparency of the building production will create conditions so that they attract domestic and foreign institutional investors which, in turn, will allow a business to implement strategic development program for the prosperity of the economy.

  3. VARIANT FOR CONSTRUCTION, REPAIR OR RECONSTRUCTION OF BUILDING

    S. N. Osipov

    2016-01-01

    Full Text Available In the XXI century moral depreciation concept comprises not only deterioration of outside appearance of construction elements in the course of time but accelerated fashion changes in respect of interior design and rapid increase in technical level for residence buildings. For this reason if average rate of building dilapidation in the buildings of series 1–335, 1–335А and 1–464А constructed in Minsk within the period of 1957–1975 and being operated till 2005–2006 has constituted 25–29 % and their moral depreciation has been equal to more than 40 % then rate of the moral depreciation has significantly increased in the XXI century. Such situation requires execution of special investigations. High operating rates of refinancing have led to the necessity for record keeping of initial expenses and repairability levels because selection of building construction, repair or reconstruction variant depends on these parameters. Repairability classification of main elements of residence buildings and premises has been proposed for regulation of such selection procedure. In this case it is recommended to take into account technological effectiveness of repair and technical service, verifiability, accessibility, easy dismountability, substitutability and interchangeability of construction elements and technical devices. The paper presents nomograms that permit to make easier practical calculations on determination of cost-efficient time period for operation of the element prior to its substitution at various refinancing rates and also for comparison of relative initial expenses according to time service.

    2014-05-01

    Full Text Available This paper builds on previous research by the authors which determined the global state-of-the-art of constructing tall buildings by surveying the most active specialist tall building professionals around the globe. That research identified the effect of wind on tower cranes as a highly ranked, common critical issue in tall building construction. The research reported here presents a design for a “Lifting Wing,” a uniquely designed shroud which potentially allows the lifting of building materials by a tower crane in higher and more unstable wind conditions, thereby reducing delay on the programmed critical path of a tall building. Wind tunnel tests were undertaken to compare the aerodynamic performance of a scale model of a typical “brick-shaped” construction load (replicating a load profile most commonly lifted via a tower crane against the aerodynamic performance of the scale model of the Lifting Wing in a range of wind conditions. The data indicate that the Lifting Wing improves the aerodynamic performance by a factor of up to 50%.

    Full Text Available This article explores ideas for linking university research entities with small- and medium-sized manufacturing industries. In an environment such as the Western Cape, South Africa, where well established teaching and research activities in science and engineering exist at several universities and research institutions, it is astonishing to realize that the local manufacturing industry struggles to obtain assistance with research and development in order to remain competitive locally and globally. Some of the reasons for this situation are outlined and solutions are proposed. In particular, the role of a gateway organization which aims to build networks between universities, research institutions and industry is described.

    Full Text Available Building Information Modelling (BIM is a process involving the creation and management of objective data with property, unique identity and relationship. In the Architecture, Engineering and Construction (AEC industry, BIM is adopted a lot in the lifecycle of buildings because of the high integration of information that it enables. Four-dimensional (4D computer-aided design (CAD has been adopted for many years to improve the construction planning process. BIM is adopted throughout buildings’ lifecycles, in design, construction and operation. This paper presents five large-scale public and financial projects that adopt BIM in the design, construction and operational phases. Different uses of BIM are compared and contrasted in the context of the separate backgrounds. It is concluded that productivity is improved where BIM is used to enable easy sharing and integration of information and convenient collaboration.

    Full Text Available The term Industrialised Building System (IBS is widely recognised by construction players in Malaysia since its first implementation since 1960s for IBS pilot projects of Pekeliling Flats and Rifle Range Flats. The aim for the implementation is to promote better system in delivering construction end-products which offers efficiency and effectiveness. At the same time, Bumiputera construction players are the majority of parties in construction industry especially in Small and Medium Enterprises (SMEs. Therefore, the purpose of this paper is to identify the perception and awareness of IBS implementation among Bumiputera players. It is found that, Bumiputera construction players have sound knowledge on the IBS and optimistic towards further implementation for future projects. Nonetheless, issues on payment methods and coordination of IBS project delivery are found to be the negative perceptions which are considered as hindrance for Bumiputera construction players’ involvement in IBS project.

    2008-11-01

    B&W Y-12 is committed to modernizing the Y-12 complex to meet future needs with a sustainable and responsive infrastructure and to integrating sustainability principles and practices into Y-12 work (Y72-001, B&W Y-12 Environmental, Safety and Health Policy). This commitment to sustainability and specifically sustainable design of buildings is also incorporated into Presidential Executive Orders (EO), DOE Orders (DOE O), and goals. Sustainable building design is an approach to design, construct, and operate facilities in an efficient and environmentally sound manner that will produce a healthful, resource-efficient and productive working environment that is inherently protective of the environment. The DOE has established the following 5 Guiding Principles for High Performance Sustainable Building (HPSB), and has issued directives that require Y-12 to incorporate the principles and a number of supporting specific practices and techniques into building design, construction and renovation projects: (1) Employ Integrated Design Principles; (2) Optimize Energy Performance; (3) Protect and Conserve Water; (4) Enhance Indoor Environmental Quality; and (5) Reduce Environmental Impact of Materials. The purpose of this document is to present the required sustainable building principles, practices and techniques, summarize the key drivers for incorporating them into Y-12 projects, and present additional recommendations and resources that can be used to support sustainable buildings to enhance the environmental and economic performance of the Y-12 Complex.

  2. Towards the carbon fibers in the building industry

    Miravete, A.

    2001-12-01

    Full Text Available There are two mainstreams in the building industry in the area of carbon fibers: rehabilitation and use as building material. The using of carbon fiber as a building material is taking place slower than as rehab system due to the very low cost of traditional building materials, the limitations of composite structure manufacturing processes and the conservative building regulations concerning materials in all the industrialized countries. However, these three issues are being solved in a very efficient way, as we will see along the coming paragraphs of this paper. This paper is split in two parts, first the carbon fiber as a material system, its typologies, manufacturing processes and industrial presentations will be described. Second, rehab and building applications will be analyzed.

    En el área de fibra de carbono en la construcción hay actualmente dos líneas de trabajo: reparaciones e implantación en obra: La implantación en la obra civil está avanzando más despacio que la utilización en reparaciones debido al bajo coste de los materiales tradicionales, a la limitación de procesos de fabricación de estructuras de materiales compuestos y al conservadurismo de las normativas de edificación y obra civil en todos los países industrializados. Sin embargo, los tres asuntos mencionados están siendo abordados con eficiencia, como se explicará más adelante. En el presente artículo, se va a describir, el primer lugar, la fibra de carbono, sus tipos, procesos de fabricación y presentaciones industriales. En segundo lugar se tratarán las aplicaciones en la construcción, haciendo énfasis en las reparaciones y en la implantación en obra civil.

    In Brazil most Construction and Demolition Waste (C&D waste) is not recycled. This situation is expected to change significantly, since new federal regulations oblige municipalities to create and implement sustainable C&D waste management plans which assign an important role to recycling activities. The recycling organizational network and its flows and components are fundamental to C&D waste recycling feasibility. Organizational networks, flows and components involve reverse logistics. The aim of this work is to introduce the concepts of reverse logistics and reverse distribution channel networks and to study the Brazilian C&D waste case.

    Full Text Available Sana’a city in Yemen is one of the oldest cities in the worlds, which has different forms of building built with different types of materials. In the present work, the old and new forms of building construction and the building materials used in Sana’a, the sources available for the new material, the effects of new material usage on building forms are all presented with the advantages and disadvantages of each material. The old shapes of buildings in Yemen and the classical and modern forms of construction using different types of materials are considered in the study. Survey is used to investigate the building forms and material types in Sana’a. Several conclusions are submitted showing that, the new building material, such as concrete block, is preferred in building comparing with old material, such as stone, which makes it the best choice for the low income people but sometimes the limited resources make old material the only available choice. Several steps needed to develop and encourage the use of new building materials are recommended.

    2008-10-01

    Full Text Available The integration of a genre-based and a corpus-based instruction in ESP learning (Swales, 1990; Tribble, 2000; Ferguson, 2001; Flowerdew, 2005 has proved to be a suitable theoretical framework for describing the lexis of construction and architecture university textbooks, such as the sample compiled in the Construction Textbooks Corpus (CTC. This paper is a contribution to the study of the formal and semantic profiles of the lexis of this particular genre type and, by way of illustration, focuses on the case study of the lemmas build and construct. From a formal standpoint, the CTC reveals that the noun building (the first content word in the CTC is six times more frequent than the verb build, and the noun construction (third in frequency is eleven times more frequent than the verb construct. Semantically, the corpus displays a prevalence of technical meanings which refer to building and construction as the activity or business of erecting edifices or structures. By observing the lexical profile of construction textbooks, this paper will finally consider possible teaching/learning implications.

    Koch, Christian; Stissing Jensen, Jens

    2007-01-01

      By viewing the construction industry as a technological innovation system (TIS) this paper discusses possible initiatives to accelerate nanotechnological innovations. The point of departure is a recent report on the application of nano-technology in the Danish construction industry, which...... concludes that opportunities are generally poorly appreciated by the industry and research communities alike. It is found that the construction industry is characterised by low-tech trajectories where dedicated innovation networks are often too fragile for innovations to stabilize and diffuse....... The institutional features of the system are furthermore poorly equipped at identifying potentials within high-tech areas. In order to exploit the potentials of nano-technology it is thus argued that an alternative TIS needs to be established. Initiatives should identify and support "incubation rooms" or marked...

    2009-09-15

    Heterogeneous photocatalysis has been intensively studied in recent decades because it only requires photonic energy to activate the chemical conversion contrasting with conventional catalysis which needs heat for thermo-activation. Over the years, the theories for photochemical activity of photocatalyst including photo-induced redox reaction and super-hydrophilic conversion of TiO{sub 2} itself have been established. The progress in academic research significantly promotes its practical applications, including the field of photocatalytic construction and building materials. TiO{sub 2} modified building materials are most popular because TiO{sub 2} has been traditionally used as a white pigment. The major applications of TiO{sub 2} based photocatalytic building materials include environmental pollution remediation, self-cleaning and self-disinfecting. The advantage of using solar light and rainwater as driving force has opened a new domain for environmentally friendly building materials. In this paper, the basic reaction mechanisms on photocatalyst surface under the irradiation of ultraviolet and their corresponding applications in building and construction materials are reviewed. The problems faced in practical applications and the trends for future development are also discussed. (author)

    2014-07-01

    Full Text Available The Zimbabwean construction industry, both in the private and public sector, is characterized by cost and time overruns. Whilst the causes are innumerable, labour productivity control, through use of effective work measurement techniques, is paramount as labour constitutes a considerable portion of any construction project. It is therefore expedient that an investigation of the work measurement techniques utilized by the industry be undertaken. Focus was made on the Midlands province, it being resident to a considerable number of mining entities undergoing building construction growth momentum on the back of significant investments since 2009. The survey was undertaken through use of interview administered questionnaires on Construction Industry Federation of Zimbabwe registered companies that are resident in the province and on those that have undertaken or are undertaking construction projects within the same province. Construction companies in the Midlands province have overwhelmingly, albeit inappropriately, used the estimating technique as alluded to by 95% of the respondents. The outputs generated from use of this technique are significantly different from the actual outputs directly causing time overruns on the project sites. The other methods of time study at 33%, work sampling at 10% and synthesis at 5% have been sparingly utilized. The results from the use of time study and work sampling in combination with the estimating technique are within the allowable limits and hence these projects have no time overrun concerns emanating from the use of these techniques.

    2013-09-01

    Full Text Available Project delay can be defined as an incident that causes extended time in order to complete all or part of a particular project successfully. In other words, delay is the time overrun, either ahead of the date for project completion specified by the contract or further than the extensive contract period where an addition of time has been granted. It should be pointed out that the project delay in the construction industry is a universal or large-scale observable fact affecting not only the construction industry but the overall economy of countries too. As far as world construction industry is concerned, project delays are common problems in the construction industries; particularly most common is in the housing development industries. This paper will present different types of project delay that took place around the world. Project delay involves diverse complicated issues all of which are continuously of crucial importance to the parties to the construction contract. These issues concern right to convalesce costs of the project delay or the need to lengthen the project with the considerable right to recovery costs for adjustments to the contract schedules.

    Full Text Available Original screw designs of buildings and columns are offered. Frameworks of these buildings and columns are the bearing elements and means of external and internal decoration of buildings and constructions. Originality of such buildings and columns frameworks is ensured by the fact that their design is decorated on the outer surface with broken or smooth screw edges and screw surfaces. Versatility of the offered screw columns trunks designs, as well as the possibility of performance of their left or right screwing allows reaching certain symmetry or their repeatability in the form of harmonious alternation of the bearing trunks of screw columns and spaces between them. Giving to numerous sides of trunks of screw columns of a certain invoice, or their coloring in different colors, will contribute even more to their expressiveness and beauty. Durability and vibration resistance (including seismic of such trunks of screw columns at the same volumes of construction materials, in comparison with round and rectangular trunks is higher

    2012-11-01

    Full Text Available Infrastructures, through externalities, modify the territorial status quo: by creating advantages and disadvantages, they lead to inequalities and territorial cohesion problems, calling for a setup of territorial equalization mechanisms. In this paper, the estimation of the costs and benefits generated from the building of the new Cispadana regional motorway (Emilia-Romagna Region, Italy is described. The study focuses on the price variations of the industrial buildings property values in the real estate market after the new motorway will be built, aiming at developing a forecasting method, which could be repeatable and applicable to other kinds of externalities. Thanks to the hedonic pricing method, which is recurring in transport literature, using a multiple linear regression model based on ordinary least squares method (OLS, the contribution of the accessibility on the industrial buildings' pricing has been isolated; it was then possible to forecast the rise in the industrial buildings prices that will be due to the accessibility variation produced by the new infrastructure. The purpose of such a procedure is the setup of equalization mechanisms, which can re-balance the territorial effects though he so-called “land value capture” tools. Thanks to a relatively quick phase of development and implementation, the  described application could be used as a tool for the ex-ante evaluation of different infrastructure projects and as an ex-post analysis tool for the monitoring of an existing infrastructure. Finally, thanks to the chance to understand the contribution of each territorial feature to the final price of the good, this application could be very useful in participatory planning processes because it could provide a common knowledge base which could be used to support the public administration’s capability of negotiation with the private partner, both in the  participatory planning processes and in the public-private partnership

  4. BIM in Malaysian Construction Industry: Status, Advantages, Barriers and Strategies to Enhance the Implementation Level

    Directory of Open Access Journals (Sweden)

    Aftab Hameed Memon

    2014-08-01

    Full Text Available Building Information Modeling (BIM is a new approach of construction design. It does not only facilitate the digital representation for designs but also provides all the necessary information for any project before it is constructed. Despite this advantage, the adoption of BIM in Malaysian construction is very low. Motivated by this, current study has focused on assessing current status of BIM implementation in Malaysian construction industry. It has also investigated advantages and disadvantages together with barriers to implementations of BIM and proposing effective strategies for enhancing the BIM implementation in construction industry. Investigation was done through survey where 150 questionnaire forms were distributed and 95 completed forms received back were analyzed with Average Index (AI and Relative Importance Index (RII method. Findings of the study revealed that the rate of BIM implementation in construction industry is very low. Major advantages of BIM are improved scheduling, improved drawing coordinated, controlling time and cost and singe detailed model. Enhanced collaboration, requires coordinated drawing, interoperability are the major disadvantages and limitations of BIM. Major barriers to low level of BIM implementation are lack of competent staff to operate the software, unawareness of the technology and non availability of parametric library. Provision of trial software, training of construction staff and introducing of BIM in university curriculum are very effective strategies in enhancing the implementation of BIM.

  5. Evaluation of Ventilation Strategies in New Construction Multifamily Buildings

    Energy Technology Data Exchange (ETDEWEB)

    Maxwell, S.; Berger, D.; Zuluaga, M.

    2014-07-01

    In multifamily buildings, particularly in the Northeast, exhaust ventilation strategies are the norm as a means of meeting both local exhaust and whole-unit mechanical ventilation rates. The issue of where the 'fresh' air is coming from is gaining significance as air-tightness standards for enclosures become more stringent, and the 'normal leakage paths through the building envelope' disappear. CARB researchers have found that the majority of high performance, new construction, multifamily housing in the Northeast use one of four general strategies for ventilation: continuous exhaust only with no designated supply or make-up air source, continuous exhaust with ducted make-up air to apartments, continuous exhaust with supply through a make-up air device integral to the unit HVAC, and continuous exhaust with supply through a passive inlet device, such as a trickle vent. Insufficient information is available to designers on how these various systems are best applied. Product performance data are based on laboratory tests, and the assumption is that products will perform similarly in the field. Proper application involves matching expected performance at expected building pressures, but there is no guarantee that those conditions will exist consistently in the finished building. This research effort, which included several weeks of building pressure monitoring, sought to provide field validation of system performance. The performance of four substantially different strategies for providing make-up air to apartments was evaluated.

    2014-07-01

    Full Text Available Proper Cost Estimate, Monitor and Control (CEM&C are vital for the success of construction projects. Starting from preliminary design to project closing, CEM&C progressively becomes more complex and challenging. Visualization can add another dimension to monitor and control where major deviations can be visually detected and analyzed. However, literature related to visualization in construction and integrating it with cost control is still in its early stages. Building Information Modeling (BIM can have promising impact in that domain. In this paper, a comprehensive cost estimating and monitoring model is presented. The model is integrated with BIM to provide the user with the capability of visualizing actual cost expended in different building elements and compare it with that budgeted at different time intervals. It provides construction practitioners with vital data that help them in taking appropriate corrective actions in case of any deviation from the budget. An example application is presented to demonstrate the capability and applicability of the model.

  20. Model code for energy conservation in new building construction

    None

    1977-12-01

    In response to the recognized lack of existing consensus standards directed to the conservation of energy in building design and operation, the preparation and publication of such a standard was accomplished with the issuance of ASHRAE Standard 90-75 ''Energy Conservation in New Building Design,'' by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., in 1975. This standard addressed itself to recommended practices for energy conservation, using both depletable and non-depletable sources. A model code for energy conservation in building construction has been developed, setting forth the minimum regulations found necessary to mandate such conservation. The code addresses itself to the administration, design criteria, systems elements, controls, service water heating and electrical distribution and use, both for depletable and non-depletable energy sources. The technical provisions of the document are based on ASHRAE 90-75 and it is intended for use by state and local building officials in the implementation of a statewide energy conservation program.

  2. The role of effective communication in the construction Industry: a guide for education and health clients

    Directory of Open Access Journals (Sweden)

    Terry Aulich

    2013-12-01

    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

    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.

    Full Text Available A large-scale workplace-based suicide prevention and early intervention program was delivered to over 9,000 construction workers on building sites across Queensland. 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.

  7. Construction waste management based on industrial management models: a Swedish case study.

    Science.gov (United States)

    Stenis, Jan

    2005-02-01

    This paper describes a methodology for estimating the true internal costs of construction waste, aimed at promoting environmentally friendly waste management. The study employs cost-benefit analysis, contribution margin analysis, the polluter-pays principle and a mathematical model: the model for Efficient Use of Resources for Optimal Production Economy (EUROPE), which has been introduced previously by the author for assigning industrial costs to waste. The calculations are performed on construction waste created in a case study of a building project. Moreover, waste is regarded as, in a business sense, having the same basic status as any normal industrial product, namely the 'equality principle'. Application of the methodology is suggested to create incentives for environmental and profitability improvement in construction companies and other types of industrial sectors. The results of the case study show the generation of construction waste to substantially decrease the final operating income, due to the internal shadow price cost it creates. This paper is intended to reduce the gap between the choice of waste management procedures and their economic impact, the overall objective being to accomplish an improved industrial environmental situation.

    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.

    Exhaust ventilation and corresponding outdoor air strategies are being implemented in high-performance new construction multifamily buildings to meet program or code requirements for improved indoor air quality, but a lack of clear design guidance is resulting in poor performance of these systems despite the best intentions of the programs or standards. CARB's 2014 'Evaluation of Ventilation Strategies in New Construction Multifamily Buildings' consistently demonstrated that commonly used outdoor air strategies are not performing as expected. Of the four strategies evaluated in 2014, the exhaust ventilation system that relied on outdoor air from a pressurized corridor was ruled out as a potential best practice due to its conflict with meeting requirements within most fire codes. Outdoor air that is ducted directly to the apartments was a strategy determined to have the highest likelihood of success, but with higher first costs and operating costs. Outdoor air through space conditioning systems was also determined to have good performance potential, with proper design and execution. The fourth strategy, passive systems, was identified as the least expensive option for providing outdoor air directly to apartments, with respect to both first costs and operating costs. However, little is known about how they actually perform in real-world conditions or how to implement them effectively. Based on the lack of data available on the performance of these low-cost systems and their frequent use in the high-performance building programs that require a provision for outdoor air, this research project sought to further evaluate the performance of passive vents.

    2008-08-21

    In the German hard coal mining industry construction materials with the most diverse compositions are required for various applications. The largest proportion of the materials is required for the construction of roadside packs and for the backfilling of roadways because of the ever increasing depths and the resulting rock mechanical problems. Over the last 30 years handling, transport and processing systems have been developed to cope with these quantities of materials and to avoid further loads on the shaft hoisting installation. Nowadays these systems are standardised and are characterised by mobility, flexibility, small space requirement and the latest control engineering. This applies in particular to pneumatic and hydraulic transport and distribution of the construction materials. In future all mines will monitor and control all installations above and below ground from a central control room. The methods developed in the mining industry are also successfully used in tunnel and underground railway construction. (orig.)

    Directory of Open Access Journals (Sweden)

    Kušar Domen

    2014-12-01

    Full Text Available Floods that have in recent years become a constant in developed areas are raising the issue of how to adapt to nature when constructing housing. The construction of retarding basins and high dikes are the most frequently used alternatives of protecting the urban environment. Such a practice is most commonly found in Europe where it however, has unfortunately shown itself on several times, not to be the most effective. People from North America who live in areas often affected by floods, build their housing on columns. In Slovenia, not much thought is given to this, which is probably the result of the traditional mentality that promotes the building of massive residential houses and the issue of structural engineering that involves the so-called soft ground floor. New materials and new structural principles make construction on columns possible, which has been proven by the example of the residential building on low bearing soil in the seismic and flood risk area of the Ljubljana Marshes.

    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.

  18. Are Innovations Being Created or Adopted in the Construction Industry? Exploring Innovation in the Construction Industry

    Directory of Open Access Journals (Sweden)

    Nor’Aini Yusof

    2014-09-01

    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.

    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.

  1. A Value Function for Assessing Sustainability: Application to Industrial Buildings

    Directory of Open Access Journals (Sweden)

    Alejandro Josa

    2010-12-01

    Full Text Available Decision support tools based on multi-attribute analysis involve the use of different types of variables. These variables are aimed at providing a framework that allows preferences to be quantified. This is particularly useful in the field of sustainability, where variables with different units are involved. One widely accepted framework for standardizing different units is the value function. Studies of value function are complex and frequently have limited physical meaning. In this context, this paper emphasizes the need to define a general equation that reflects the preferences of the decision maker in a clear and easily applied way. The paper proposes a new general equation that fulfils these requirements. By modifying certain parameters, this general equation represents the most commonly used relationships (linear, convex, concave and S-shaped. The proposed equation is finally applied to four variables used in the field of industrial buildings and sustainability.

Although traditional, that segment has undergone many changes in the business model as a result of major technological advances, requiring companies to adapt to the new conditions, incorporating new technologies, materials and developing new processes, considered innovative. With the purpose of studying in depth this process a research with a qualitative single case study was conducted in an industrial building company, located in the metropolitan area of Porto Alegre, through in-depth interviews, analysis of the narratives and of documents. The results showed characteristics that required a specific design of the strategy, management practices and coordination of organizational resources, which allowed the company to become a reference in the sector.

    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.

  5. Driving Innovative Thinking in the New Zealand Construction Industry

    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.

    Full Text Available The BRITE (Building Research Information Technology and Environment project was established by the Australian Cooperative Research Centre for Construction Innovation to encourage innovation in the construction industry. While innovation is generally perceived to be broadly beneficial, there has been little formal study of its occurrence or impact in Australian construction or of the factors which foster an innovative atmosphere within an enterprise. In order to benchmark innovation performance, the BRITE project conducted a survey in 2004 into the nature, incidence and variety of technological and organisational innovations in various sectors of the industry. With some exceptions, the survey found that clients and consultants engaged in significantly higher levels of innovation than did suppliers, main contractors or trade contractors. Within the industry sectors those organisations classified as high innovators favoured the adoption of advanced management practices and had formal evaluation systems in place to judge their progress. They reported significant positive impacts on their profitability from innovation and can therefore provide instructive examples for the rest of the industry to follow.

    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.

    Full Text Available This paper examined the relative importance of the project success criteria in the Nigerian construction industry. It also determined the correlation among the project success criteria. Based on the literatures reviewed, the study proposed a framework for measuring project success in the construction industry. The respondents for the study were the government, private clients, consultants and contractors. Three hundred copies of questionnaires were distributed to capture data on the subject, but only 86 were returned and used for the study. The paper captured respondents that are resident in Lagos state, Nigeria and chosen by convenience from selected organizations used for the study. The data were analysed with SPSS 16 through the use of frequencies, mean scores, factor analysis and correlation. Factor analysis was employed because the mean scores showed that all the project success criteria were at least important. Nine principal components were finally merged into 4 through the factor analysis using the Varimax rotation with Keiser normalization. The study found out that all the project success criteria were important but their level of importance differs according to the factor analysis carried out. Therefore, it was concluded that there are four major components of construction project success in Nigeria- user-related factors, professionals’ factors, organisational factors and other minor factors. The minor factors were found to be related to both organizations and projects but were not highly rated by respondents for determining construction project success. The study also concludes that project success criteria goes beyond meeting cost, time and quality target, it includes users’ satisfaction, professionals’ fulfilment and achievement of organizational goals. The recommendation of the study was that for construction projects to be successful, attention must be paid to users’ related factors, professionals’ factors and

    Full Text Available Here we are synthetically describing some constructive peculiarities of Venice civil buildings, analyzing the relation with the features of their structural decay and behavior in the long run. We suppose Venetian buildings, especially those parts which are conceived to suit the lagoon environment, to have undergone an evolution made of some adjustments, which were based on the observation of damages in previous buildings. That is we suppose ancient builders to rely on their awareness of the behavior of structures yet to come, and to be able to forecast it in part. This process brought some building contrivances to perfection, as exclusive and enduring features of Venice, overcoming changes in style and architectural layout, till they grew into essential elements of a whole and adaptable “device”. This writing is meant for a concise interpretation of this device, which is the result of some research works carried out at Venice IUAV University.

Se aventura la hipótesis que las construcciones venecianas y, en particular, algunos de sus detalles, concebidos específicamente para la laguna donde se enclava, han sido objeto de una adaptación evolutiva a través de la observación de los problemas estructurales de los edificios precedentes. Los alarifes venecianos aprendieron a tener en cuenta el comportamiento estructural posterior del edificio, que previeron en cierta medida. Este proceso ha llevado a perfeccionar algunos detalles constructivos exclusivos de Venecia que han perdurado en el tiempo, que han resistido impertérritos a mutaciones de estilo y de configuración arquitectónica, hasta constituir elementos esenciales de un aparato indivisible y adaptable cuya interpretaci

    Full Text Available Modular coordination (MC is recognized as a tool towards rationalization and industrialization. The implementation of MC concept in the design stage may improve the constructability and construction time. However, the implementation of MC in Industrialized Building System (IBS implementation is still low compare to other developed countries such as the United Kingdom, Sweden and Japan. This paper examined the interrelationship between motivational factors of stakeholders in adopting MC concept using Interpretative Structural Modeling (ISM. Questionnaire survey was engaged in this study to identify significant motivational factors. Then, semi-structure interviews were used to collect qualitative data. ISM was adopted to build relationship between factors and develop an initial model to promote the adoption of MC in IBS construction. Seven (7 significant motivational factors were identified in this research namely 1 ‘stakeholder’s commitment’, 2 ‘reduce site disruption’, 3 ‘increase productivity’, 4 ‘high skilled workers’, 5 ‘site sustainability (environment, economy and social benefits’ 6 ‘standardization’ and 7 ‘enabling ‘open building’ concept’. The result using Matrice d’Impacts Croises Multiplication Applique an Clasment (MICMAC shows that there are three factors can be categorized as Independent / Driving Factors namely ‘stakeholder’s commitment’, ‘standardization’ and ‘enabling “open building” concept’. These factors should be explored in details to enhance the adoption of IBS in Malaysia. The findings provide a very good platform for a further research in formulating an efficient solution to promote MC concept adoption among the stakeholders. This scenario will improve the deliverables of IBS construction and eliminate negative perception in its implementation.

    2007-12-01

    Full Text Available The article contains a synthesis of the different factors involved in the alteration of granite ashlars or cladding used in building construction. Emphasis is placed on the – primarily fissure-like – anisotropies often present in granite, which are usually related to the structural conditions of the quarry where it is mined. Such anisotropies condition the development of certain types of alterations that appear over time, particularly in ashlars. Stone petrography, particularly as regards the chemical composition of the minerals comprising granite, also govern its alteration. Moreover, the commercial term granite often includes other more alkaline rocks generically known as granitoids, whose alterability is higher than in granite per se. The values of some of the physical properties of these rocks, which must be quantified to evaluate their durability, are shown to differ in keeping with their anisotropy. Finally, the forms, causes and mechanisms involved in granite decay are reviewed in the context of its use in building construction.En el artículo se sintetizan los diversos aspectos que inciden en la alteración de las rocas graníticas, cuando estas se utilizan en los edificios, ya sea en forma de sillares o de losetas de revestimiento. Se hace especial hincapié en las anisotropías, fundamentalmente de carácter fisural que suelen presentar los granitos. Estas suelen estar relacionadas con las condiciones estructurales del yacimiento del cual proceden. Dichas anisotropías condicionan el desarrollo de determinadas formas de alteración que con el paso del tiempo se aprecian, sobre todo en los sillares. También se recuerda que la petrografía, y en especial la composición química de los minerales que componen las rocas graníticas, condicionan su alteración, y que dentro del término comercial granito se suelen incluir otras rocas más alcalinas denominadas genéricamente granitoides y más alterables que el granito sensu

    Full Text Available The use of e-commerce systems has increased substantially in the past five years, and now a number of companies in the construction industry have joined consortiums to develop e-commerce portals. These new systems encourage companies to review the way in which existing processes are undertaken, and often re-engineered process are introduced. It is important to understand the difference between the terms e-commerce and e-business, e-commerce refers to buying and seeling transactions which use some24The Australian Journal of Construction Economics & Building Page (iiiform of electronic media, while e-business suggests a review and redefinition of business models linked to the greater use of IT. It is argued that the greater use of the internet and e-commerce, and the move towards the integration of applications will compel construction companies to re-engineer processes and introduce e-commerce systems. A series of business drivers and business designs are discussed in later sections of this paper.There are many benefits associated with the introduction of e-commerce systems, and these include increases in GDP, real wages and employment together with reduced transaction costs. It has been forecast that there will be more than 400,000 companies in Australia using e-commerce systems by 2005 (NOIE 2000. For the construction industry, the benefits will include increased project efficiencies, communications, control, and reduced design and construction times as well as reduced costs (BuildOnline 2000. In the past year, two local consortiums have been formed to develop and offer e-commerce applications, and this heightens the need for all companies to reflect on how they might engage with these new technologies.

    The position determination inside a building where no GPS signal is being received can be ascertained using laser transmitters in industrial situations where there are no people or using triangulation of the signal strength, normally electro-magnetic signals, if the required accuracy is more than a metre. Our solution is aimed at situations where people are present and where the required accuracy is less than 30 cm, such as in shopping precincts or supermarkets. To achieve this, a network of ultrasonic transmitters is fitted into the ceiling which receives a synchronised time signal. Each transmitter has a unique identifier code and emits its code with a delay with respect to the common time signal which is proportional to its code number with an ASK modulation over the ultrasonic band centred on 40 KHz. The receivers circulating beneath the transmitters receive the codes of those within their detection range, translate the time delays into distances and then obtain their position by triangulation since the receivers know the position of every transmitter. Since the receivers are not synchronised with the common time signal or the actual speed of the sound, whose value varies appreciably with temperature, relative humidity and atmospheric pressure, a consecutive approximation algorithm has been introduced. This is based on the fact that the Z coordinator of the receiver is known and constant and thus it is possible, with only three different identifiers received, to deduce the phase of the common time signal and estimate the speed of the sound with a fourth identifier.

    1993-06-01

    This study was undertaken to determine the possibility of developing beneficial uses for carbon dioxide as a key component for a large-volume building product. Such a use may provide an alternative to storing the gas in oceanic sinks or clathrates as a way to slow the rate of global warming. The authors investigated the concept that carbon dioxide might be used with other chemicals to make carbon-dioxide-based polymers which would be lightweight, strong, and economical alternatives to some types of wood and silica-based building materials. As a construction-grade material, carbon dioxide would be fixed in a solid, useful form where it would not contribute to global warming. With the probable imposition of a fuel carbon tax in industrialized countries, this alternative would allow beneficial use of the carbon dioxide and could remove it from the tax basis if legislation were structured appropriately. Hence, there would be an economic driver towards the use of carbon-dioxide-based polymers which would enhance their future applications. Information was obtained through literature searches and personal contacts on carbon dioxide polymers which showed that the concept (1) is technically feasible, (2) is economically defensible, and (3) has an existing industrial infrastructure which could logically develop it. The technology exists for production of building materials which are strong enough for use by industry and which contain up to 90% by weight of carbon dioxide, both chemically and physically bound. A significant side-benefit of using this material would be that it is self-extinguishing in case of fire. This report is the first stage in the investigation. Further work being proposed will provide details on costs, specific applications and volumes, and potential impacts of this technology.

  7. Program package for constructing analytical models of industrial robots

    Energy Technology Data Exchange (ETDEWEB)

    Vukobratovich, M.; Kirchanskiy, N.

    Complex multidimensional nonlinear dynamic systems are controlled with the use of control computers differing in their complexity, from large ones at the level of the modeling of the dynamics of the system and synthesis of the control algorithm to microcomputers directly controlling the system. One of the main decisive problems in controlling an industrial robot is the generation of a dynamic on-line model. For this purpose, a separate microcomputer or several computers operating in the multiprocessor mode are used. The existing methods of robot dynamics simulation which are based on the equations of Newton-Euler, Lagrange and others require a large number of numerical operations and they cannot be realized in real time: the time spent on the construction of a model is several times greater than that acceptable for the computer. This is explained by the following factors: complexity of the mathematical model, the use of a high-level language for programming, the desire to construct an algorithm of a general kind, which leads to high redundancy of numerical operations; the use of recursion relations, which excludes the possibility of performing parallel operations during the realization in a computer. Special characteristics of the construction of a program system which is to a considerable degree free of the above drawbacks is considered below. Instead of directly constructing a model in the numerical form on the basis of one of the approaches of classical mechanics, the concept of constructing a model in symbols is proposed here. It is possible to show that in this way it is possible to obtain a compact mathematical model which requires fewer numerical operations (multiplication, addition) for its realization by two orders in comparison with the methods used earlier. 9 references, 2 tables.

    Full Text Available Construction is one of the important industries employing a large number of people on its workforce. A wide range of activities are involved in it. Due to the advent of industrialization and recent developments, this industry is taking a pivotal role for construction of buildings, roads, bridges, and so forth. The workers engaged in this industry are victims of different occupational disorders and psychosocial stresses. In India, they belong to the organized and unorganized sectors. However, data in respect to occupational health and psychosocial stress are scanty in our country. It is true that a sizable number of the workforce is from the unorganized sectors − the working hours are more than the stipulated hours of work - the work place is not proper − the working conditions are non-congenial in most of the cases and involve risk factors. Their wages are also not adequate, making it difficult for them to run their families. The hazards include handling of different materials required for construction, and exposure to harsh environmental conditions like sun, rain, and so on. On account of this, in adverse conditions, it results in accidents and adverse health conditions cause psychosocial strain and the like. They are victims of headache, backache, joint pains, skin diseases, lung disorders like silicosis, other muscular skeletal disorders, and so on. The repetitive nature of the work causes boredom and the disproportionate earning compared to the requirements puts them under psychological stress and strain and other abnormal behavioral disorders. The Government of India has realized the importance of this industry and has promulgated an Act in 1996. The state government are being asked to adhere to this, although only a few states have partially enforced it. In this article, attempts have been made to review some of the important available articles for giving a broad idea of the problem and for furtherance of research in this field.

On account of this, in adverse conditions, it results in accidents and adverse health conditions cause psychosocial strain and the like. They are victims of headache, backache, joint pains, skin diseases, lung disorders like silicosis, other muscular skeletal disorders, and so on. The repetitive nature of the work causes boredom and the disproportionate earning compared to the requirements puts them under psychological stress and strain and other abnormal behavioral disorders. The Government of India has realized the importance of this industry and has promulgated an Act in 1996. The state government are being asked to adhere to this, although only a few states have partially enforced it. In this article, attempts have been made to review some of the important available articles for giving a broad idea of the problem and for furtherance of research in this field.

    2014-08-01

    NREL experienced a significant increase in employees and facilities on our 327-acre main campus in Golden, Colorado over the past five years. To support this growth, researchers developed and demonstrated a new building acquisition method that successfully integrates energy efficiency requirements into the design-build requests for proposals and contracts. We piloted this energy performance based design-build process with our first new construction project in 2008. We have since replicated and evolved the process for large office buildings, a smart grid research laboratory, a supercomputer, a parking structure, and a cafeteria. Each project incorporated aggressive efficiency strategies using contractual energy use requirements in the design-build contracts, all on typical construction budgets. We have found that when energy efficiency is a core project requirement as defined at the beginning of a project, innovative design-build teams can integrate the most cost effective and high performance efficiency strategies on typical construction budgets. When the design-build contract includes measurable energy requirements and is set up to incentivize design-build teams to focus on achieving high performance in actual operations, owners can now expect their facilities to perform. As NREL completed the new construction in 2013, we have documented our best practices in training materials and a how-to guide so that other owners and owner's representatives can replicate our successes and learn from our experiences in attaining market viable, world-class energy performance in the built environment.

    Recently the demand and number of applications of full-field, optical measurement methods based on noncoherent light sources increased significantly. They include traditional image processing, thermovision, digital image correlation (DIC) and structured light methods. However, there are still numerous challenges connected with implementation of these methods to in-situ, long-term monitoring in industrial, civil engineering and cultural heritage applications, multimodal measurements of a variety of object features or simply adopting instruments to work in hard environmental conditions. In this paper we focus on 3D DIC method and present its enhancements concerning software modifications (new visualization methods and a method for automatic merging of data distributed in time) and hardware improvements. The modified 3D DIC system combined with infrared camera system is applied in many interesting cases: measurements of boiler drum during annealing and of pipelines in heat power stations and monitoring of different building steel struts at construction site and validation of numerical models of large building structures constructed of graded metal plate arches.

  12. Economic assessment of the construction industry: A construction-economics nexus

    Science.gov (United States)

    Barber, Herbert Marion, Jr.

    The purpose of this study was to conduct an economic assessment of the construction industry. More specifically, this study addresses ambiguities within the literature that are associated with the construction-economics nexus. The researcher 1) investigated the relationships between economic indicators and stock prices of U.S. construction equipment manufacturers, 2) investigated the relationships between energy production, consumption, and corruption, and 3) determined the economic effect electricity generation and electricity consumption has on economies of scale. The researcher used descriptive and inferential statistics in this study and determined that economists, researchers, policy-makers, and others should have predicted the 2007-08 world economic collapse 5-6 years prior to realization of the event given that construction indices and GDP grossly regressed from statistically acceptable trends as early as 2002 and perhaps 2000. Substantiating this claim, the effect of the cost of construction materials and labor, i.e. construction index, on GDP was significant for years leading up to the collapse (1970-2007). Additionally, it was determined that energy production and consumption are predictors of governmental corruption in some countries. In the Republic of Botswana, for example, the researcher determined that energy production and consumption statistically jointly effected governmental corruption. In addition to determining statistical effect, a model for predicting governmental corruption was developed based on energy production and consumption volumes. Also, the researcher found that electricity generation in the 25 largest world economies had a statistically significant effect on GDP. Electricity consumption also had an effect on GDP, as well, but not on other economic indicators. More importantly than the quantitative findings, the researcher concluded that the construction-economics nexus is far more complex than most policy-makers realize. As such

    1986-09-01

    "The sick-building syndrome" (WHO) is reported with increasing intensity in non-industrial places of work, such as schools, kindergartens, and offices, all of which have a heavy load of traffic (people). The construction of these buildings (e.g. flat roofs) often leads to water damage with subsequent microbial growth. Further, reduced cleaning budgets in connection with the wide use of needle-felt carpets, as well as ventilation systems not regularly maintained, will lead to pollution by dust and microorganisms. A systematic registration of dust and microbial parameters has been carried out since 1980 in buildings with indoor climate complaints, in order to elucidate the possible influence of these factors.

    2011-09-01

    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.

    2012-12-01

    Full Text Available Purpose of this paper: Procurement systems are vital in ensuring the successful implementation of construction projects precisely in all the phases of any particular project. Therefore, this paper aims to investigate in a systematic manner the factors that influence the selection of a procurement system in the South African construction industry. Research methodology: An extensive theory and literature review of procurement systems was conducted. The literature reviewed included a sample of case studies of procurement systems successfully implemented in completed building and civil engineering projects in South Africa. A questionnaire using a four-round Delphi survey method was used to conduct the empirical study in order to obtain participants' opinions about factors influencing the selection of procurement systems as well as the utility value of various procurement systems on each factor as identified. Finally, data analysis of both qualitative and quantitative techniques was performed using the Statistical Package for Social Sciences (SPSS. Findings: After qualitative analysis, findings of the literature reviewed suggest that factors that influence the selection of procurement systems cut across all the phases of the project as identified in this paper. Therefore, these factors are categorically classified into internal and external factors. Factors from the internal environment were further classified into client characteristics and project characteristics, with client characteristics comprising of variables such as clients' level of knowledge and control, political and social consideration, familiarity of procurement systems, competition, funding arrangement, government public/private sector projects and risk allocation whereas project characteristics comprise of factors (variables such as size and technical complexity of the project, influence of the project life cycle, expedited project delivery, time, quality and price certainty.

  4. Prediction of final settlements of buildings constructed on expansive soils

    Directory of Open Access Journals (Sweden)

    María-de-la-Luz Pérez-Rea

    2015-06-01

    Full Text Available Because the action of the swelling pressure, the settlements caused by the transmitted load from the structure on expansive soils, and the settlements calculated by classic theories of soils mechanics are different. This swelling pressure acts in opposite direction to the weight of the building. In this paper, the authors propose the use of a volumetric strain coefficient by settlements exp, in a soil-structure interaction algorithm taking into account the expansive soil behavior in the reduction of the settlement magnitude when a building is placed above soil. It’s necessary to know the initial properties of the expansive unsaturated soil and the load building conditions. A laboratory process is described for determining the aexpcoefficient.

  5. Building healthy communities: establishing health and wellness metrics for use within the real estate industry.

    Trowbridge, Matthew J; Pickell, Sarah Gauche; Pyke, Christopher R; Jutte, Douglas P

    2014-11-01

    It is increasingly well recognized that the design and operation of the communities in which people live, work, learn, and play significantly influence their health. However, within the real estate industry, the health impacts of transportation, community development, and other construction projects, both positive and negative, continue to operate largely as economic externalities: unmeasured, unregulated, and for the most part unconsidered. This lack of transparency limits communities' ability to efficiently advocate for real estate investment that best promotes their health and well-being. It also limits market incentives for innovation within the real estate industry by making it more difficult for developers that successfully target health behaviors and outcomes in their projects to differentiate themselves competitively. In this article we outline the need for actionable, community-relevant, practical, and valuable metrics jointly developed by the health care and real estate sectors to better evaluate and optimize the "performance" of real estate development projects from a population health perspective. Potential templates for implementation, including the successful introduction of sustainability metrics by the green building movement, and preliminary data from selected case-study projects are also discussed.

  6. Building Information Modelling and Standardised Construction Contracts: a Content Analysis of the GC21 Contract

    Directory of Open Access Journals (Sweden)

    Aaron Manderson

    2015-08-01

    Full Text Available Building Information Modelling (BIM is seen as a panacea to many of the ills confronting the Architectural, Engineering and Construction (AEC sector. In spite of its well documented benefits the widespread integration of BIM into the project lifecycle is yet to occur. One commonly identified barrier to BIM adoption is the perceived legal risks associated with its integration, coupled with the need for implementation in a collaborative environment. Many existing standardised contracts used in the Australian AEC industry were drafted before the emergence of BIM. As BIM continues to become ingrained in the delivery process the shortcomings of these existing contracts have become apparent. This paper reports on a study that reviewed and consolidated the contractual and legal concerns associated with BIM implementation. The findings of the review were used to conduct a qualitative content analysis of the GC21 2nd edition, an Australian standardised construction contract, to identify possible changes to facilitate the implementation of BIM in a collaborative environment. The findings identified a number of changes including the need to adopt a collaborative contract structure with equitable risk and reward mechanisms, recognition of the model as a contract document and the need for standardisation of communication/information exchange.

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.

    Full Text Available The Just-in-Time (JIT philosophy originated from the Toyota Production System (TPS and has been used in the manufacturing industry for many decades. It has helped to increase the productivity of the industry and has also increased the quality of its products. In recent years, numerous studies in developed countries have endeavoured to introduce JIT in the construction industry to reap similar benefits. This study focused on applying JIT to the Chinese construction industry with the goal of improving its performance and thus its competitiveness. This paper discusses the current state of the Chinese construction industry; presents the potential impediments to implementing JIT; and proposes a framework for JIT implementation in the areas of design, procurement, construction and inspection. The results of this study suggest that government and educational institutions should play a key role in spearheading the application of JIT in the construction industry in China.

  12. Ontology-Based Representation and Reasoning in Building Construction Cost Estimation in China

    Directory of Open Access Journals (Sweden)

    Xin Liu

    2016-08-01

    Full Text Available Cost estimation is one of the most critical tasks for building construction project management. The existing building construction cost estimation methods of many countries, including China, require information from several sources, including material, labor, and equipment, and tend to be manual, time-consuming, and error-prone. To solve these problems, a building construction cost estimation model based on ontology representation and reasoning is established, which includes three major components, i.e., concept model ontology, work item ontology, and construction condition ontology. Using this model, the cost estimation information is modeled into OWL axioms and SWRL rules that leverage the semantically rich ontology representation to reason about cost estimation. Based on OWL axioms and SWRL rules, the cost estimation information can be translated into a set of concept models, work items, and construction conditions associated with the specific construction conditions. The proposed method is demonstrated in Protégé 3.4.8 through case studies based on the Measurement Specifications of Building Construction and Decoration Engineering taken from GB 50500-2013 (the Chinese national mandatory specifications. Finally, this research discusses the limitations of the proposed method and future research directions. The proposed method can help a building construction cost estimator extract information more easily and quickly.

    This interdisciplinary study discusses challenges in energy economising in Norway as they involve the architect profession and their role in affecting the energy standard in buildings. The main research question is separated into two component research questions. The first is to analyse how the reality orientation of the architect profession is constituted and maintained, and how this in turn influences their values in connection to energy related decisions. How is the architects' professional role conception reflected in the educational system and architect journals, and how is it expressed among the 'green outsiders' of the profession? The second component research question is related to decision-making processes regarding design processes, particularly concerning energy in buildings and the role played by the architects in these processes as they interact with other actors and within institutional frames.

  2. Risk Factors of Building Apartments for University Talent through the Agent Construction Mode in China: Interrelationship and Prioritization

    Directory of Open Access Journals (Sweden)

    Zhengrong Liu

    2016-03-01

    Full Text Available Apartments for university talent (AUT, are apartments provided to staff at non-market price, in order to attract outstanding scholars from around the world to work in universities and improve educational quality. This has been a critical issue in achieving social sustainability in China during rapid urbanization and industrialization. The agent construction mode has been adopted to build AUT because universities usually lack relevant management experience. The agent construction mode is a type of turnkey engineer construction based on the principal-agent model, project bidding mode, engineering contracting projects, and project supervision system. Risk factors are important considerations for both universities and agent construction companies. Although some studies have investigated the risk factors, only a few studies have identified the hierarchical structure of relevant risk factors. Therefore, the interrelationship and prioritization of the risk factors remain unknown, and this situation presents a barrier to better risk management. This paper investigates the interrelationship of risk factors with interpretative structural modeling (ISM. In addition, fuzzy MICMAC (matric d’impacts croises-multiplication appliqué a un classemen analysis was conducted to prioritize the risk factors. The findings provide useful references for better risk management of building AUT through the agent construction mode. Although this study focuses on China, the analytical process can also be generalized to other research topics and other countries.

    2010-12-01

    Full Text Available Studies on market convergence are well considered in the literature. However, the majority of the previous research focused on housing markets and few studies have concentrated on construction markets. Owing to a simultaneously dramatic increase in the construction prices of the sub-markets in the building construction sector in Australia, this paper aims to identify the convergence among these markets, involving house construction market, other-residential building construction market, and non-residential building construction market. To achieve it the Granger causality test and generalized response function depending on the vector error correction model with the quarterly data of Australia’s eight states from 1998 to 2010 will be applied. Based upon the econometric tests, the price diffusion patterns among these construction markets have been identified. Research on the convergences of construction markets not only helps construction firms perform well in business operations and arbitrage activities, but also provides policy makers with useful information for enacting effective construction policies for national perspectives and approaches to infrastructure planning.

    Mahyar Maali; Abdulkadir Cüneyt Aydin; Merve Sağiroğlu

    2015-10-01

    The design of a runway beam for overhead cranes is of great importance when constructing steel structures, as is the lateral-torsional buckling (LTB) value obtained for I-beam sections. Therefore, engineers must always consider the optimal design of these beams under overhead cranes loads. In this study, runway beams of three overhead crane groups were analyzed for LTB, and a sinusoidal runway beam body was developed. These runway beams with different sinusoidal angles were analyzed by using the finite element method (ABAQUS) and compared to each other and other runway IPE-IPN beam sections; furthermore, all models were compared with the Canadian Institute of Steel Construction standard. As a result, a new method was proposed for developing sinusoidal runway beams for overhead cranes. The sinusoidal runway beam has lower weight than runway IPE-IPN beam sections. Ultimately, a sinusoidal beam body was developed practically with a scale of 1:1.

    2014-07-01

    In multifamily buildings, particularly in the Northeast, exhaust ventilation strategies are the norm as a means of meeting both local exhaust and whole-unit mechanical ventilation rates. The issue of where the "fresh" air is coming from is gaining significance as air-tightness standards for enclosures become more stringent. CARB researchers have found that most new high performance, multifamily housing in the Northeast use one of four strategies for ventilation: continuous exhaust only with no designated supply or make-up air source, continuous exhaust with ducted make-up air to apartments, continuous exhaust with supply through a make-up air device integral to the unit HVAC, and continuous exhaust with supply through a passive inlet device, such as a trickle vent. Insufficient information is available to designers on how these various systems are best applied. Product performance data are based on laboratory tests, but there is no guarantee that those conditions will exist consistently in the finished building. In this research project, CARB evaluated the four ventilation strategies in the field to validate system performance.

  18. Infrared Thermographic Quality Control For Newly Constructed Office Buildings Prior To Closing

    Science.gov (United States)

    Allen, Sharon

    1987-05-01

    The use of infrared thermographic building diagnostics, prior to final closing, is an effective method of quality control. Thermal envelope studies using infrared technology, made prior to contractual release, are a cost effective means of insuring the buyer and builder that the thermal envelope performs to the specifications of the construction contract. Building owners and builders can both benefit. Builders are able to close jobs and avoid costly call backs after occupancy. Building owners gain knowledge as to how the building envelope can be expected to perform in coming seasons. A majority of problems can be avoided during construction when infrared thermographic building diagnostics are introduced at the beginning of a project. Problems may be dealt with during construction, not afterwards. Contractors are alerted to how their job affects the performance of other trades and materials in the structure. To gain the most from infrared thermography during the construction phase, the contractors and thermographer must have an understanding of each other's function. On-site visits during construction can provide contractors with a basic background of thermal imaging and familiarize the thermographer with various construction techniques and materials used.

    Directory of Open Access Journals (Sweden)

    VAISHALI SAHU

    2013-02-01

    Full Text Available A large quantity of sludge rich in nutrients and microorganisms is generated every year from water and wastewater treatment plants, the final destination of which affects the environment. Generally, dewatered sludge is disposed of by spreading on the land or by land filling. However, space limitations on existing landfill sites and problems of waste stabilization have prompted investigation into alternative reuse techniques and disposal routes for sludge. A more reasonable approach is to view the sludge as a resource that can be recycled or reused. Many researchers have exploited the reuse of lime sludge from water treatment plant and sewage sludge ash as an inexpensive source of soil stabilizer in sub grade stabilization and soft cohesive soil respectively. Sewage sludge pellets (SSP has replaced sand in concrete manufacturing for pavements. The use of SSP as substituting material in raw mix formulation in Portland cement manufacturing has been studied by many researchers. Experimental results showed the feasibility of the partial replacement (15 and 30% of cement by sewage sludge ash (SSA in mortars. This paper highlights the potential of dried sludge, sludge pellets and sludge ash in various building materials for construction.

This study hasbeen conducted by means of a survey questionnaire. Seventythreequestionnaires were distributed to target constructioncontractors and twenty-five questionnaires to public owners. Sixtycompleted questionnaires from contractors and twenty-threequestionnaires from public owners were received and analysed.The survey results indicated that contemporary project timemanagement tools and techniques are not widely used amonglocal contractors and owners. Lack of subcontractor’s knowledgeand awareness of the importance of project time managementtools and techniques are still major obstacles toward the efficientutilisation of such tools. This study recommended that there is anurgent need to establish a professional industry body such as anInstitute of Building to review and evaluate existing local projectmanagement practices. This professional body may be establishedby the government through the Ministry of Housing and PublicWorks or by the local university in cooperation with a similarinternational professional industry body. Current training effortshould be tailored to encourage owners and contractors to usework breakdown structures, resource optimisation, and networkscheduling.

    Full Text Available Cities are the center of population aggregation and human economic activities. They are important drivers of economic and social development, and are also a basic element in creating a country’s competitiveness. Building sustainable cities and promoting the region’s economic prosperity is a fundamental goal of local governments. As economic development gradually becomes driven by knowledge and innovation, the economic functions of key cities also transform to become a gathering place for resources—such as knowledge and technology—and playing the role of knowledge proliferation. This then leads to the concurrent development of the surrounding areas. Therefore, connecting innovation and urban development and creating sustainable and innovation-orientated cities has become a major development focus for international cities.

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.

    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.

    Presently, appropriate waste management is one of the main requisites for sustainable development; this task is tackled by the material construction industry. The work described herein is focused on the valorization of granite waste through incorporation, as a filler-functional admixture, into cement-based mortar formulations. The main components of the waste are SiO(2) (62.1 %), Al(2)O(3) (13.2 %), Fe(2)O(3) (10.1 %), and CaO (4.6 %). The presence of iron oxides is used to develop the photocatalytic properties of the waste. Following heating at 700 °C, α-Fe(2)O(3) forms in the waste. The inclusion of the heated sample as a filler admixture in a cement-based mortar is possible. Moreover, this sample exhibits a moderate ability in the photodegradation of organic dye solutions. Also, the plastering mortars, in which the heated samples have been used, show self-cleaning properties. The preparation of sustainable building materials is demonstrated through the adequate reuse of the granite waste.

    The objective for this project was to develop a model as a basis for calculation of environmental profile for whole building constructions, based upon data from databases and general LCA software, in addition to the model structure from the Nordic project on LCC assessment of buildings. The model has been tested on three building constructions; timber based, flexible and heavy as well as heavy. Total energy consumption and emissions contributing to climate change are calculated in a total life cycle perspective. The developed model and exemplifying case assessments have shown that a holistic model including operation phase is both important and possible to implement. The project has shown that the operation phase causes the highest environmental loads when it comes to the exemplified impact categories. A suggestion on further development of the model along two different axes in collaboration with a broader representation from the building sector is given in the report (author)(tk)

    According to Wortmann classification, the Building Industry (BI) can be defined as engineer-to-order (ETO) industry: the engineering-process starts only when an order is acquired. This definition implies that every final product (building) is almost unique’ and processes cannot be easily standardized or automated. Because of this, BI is one of the less efficient industries today’ mostly leaded by craftsmanship. In the last years’ several improvements in process efficiency have been made focusing on manufacturing and installation processes only. In order to improve the efficiency of design and engineering processes as well, the scientific community agrees that the most fruitful strategy should be Front-End Design (FED). Nevertheless, effective techniques and tools are missing. This paper discusses outcomes of a research activity that aims at highlighting whether Parametric and Generative Design techniques allow reducing wastes of resources and improving the overall efficiency of the BI, by pushing the Digitalization of design and engineering processes of products. Focusing on the Glued-Laminated-Timber industry, authors will show how Parametric and Generative Design techniques can be introduced in a standard supply-chain system, highlighting potentials and criticism on the supply-chain system as a whole.

    Full Text Available This paper presents the results of an experimental study that was conducted in 15 office buildings in the humid and cold tropics during the working hours of the dry and rainy seasons in Cameroon. This was with the aim to study the effects that local and imported materials had on indoor air quality. To achieve this objective, the adaptive model approach has been selected. In accordance with the conditions of this model, all workers were kept in natural ventilation and, in accordance with the general procedure, a questionnaire was distributed to them, while variables, like air temperature, wind speed, and relative humidity were sampled. The results showed a clear agreement between expected behaviour, in accordance with the characteristics of building construction, and its real indoor ambience once they were statistically analysed. On the other hand, old buildings showed a higher percentage of relative humidity and a lower degree of indoor air temperature. Despite this, local thermal comfort indices and questionnaires showed adequate indoor ambience in each group of buildings, except when marble was used for external tiling. The effect of marble as an external coating helps to improve indoor ambience during the dry season. This is due to more indoor air and relative humidity being accumulated. At the same time, these ambiences are degraded when relative humidity is higher. Finally, these results should be taken cognisance of by architects and building designers in order to improve indoor environment, and overcome thermal discomfort in the Saharan area.

    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.

    Full Text Available From early times, building and civil engineering construction has been a male dominated industry. But in today’s contemporary times, the women folk have broken this monotony of male domination. This is evident in the building and engineering industry. Isoko land in the south of Delta State, although women have broken from the stereotype of home keeping into construction, their level of engagement is at the lowest ebb as casual and unskilled workers. This study looks at the factors that encourage female to engage in construction especially at the lowest ebb and the implications for the woman, society, and construction industry. Oral interview methodology was adopted in this study. The response of five local contractors/employers and 60 women interviewed at construction site formed the data for this study. A simple percentage was used to analyze data generated. Findings reveal that poverty and unemployment, lack of education and skill, family responsibility and environmental factors top the reasons. Policies that encourage and make it mandatory for women to progress in education and skill acquisition, provide a future for women in construction and stop discrimination against women will be a step in the right direction. Such policies are recommended.

    Full Text Available The size of farms has increased considerably during Finland's EU membership. The growth has meant big investments in the new production buildings. The buildings have been switched to big industrialhall- like constructions from small-scale ones which have contained own timber and own work contribution. The objective of the project financed by Farmers' Social Insurance Institution was to improve occupational safety on farm building construction and renovation sites by disseminating current safety practices and by developing ways of action which are better than the prevailing ones. The project consisted of a literature review, statistical analysis, as well as a farmer and designer interviews. In the statistical analysis the MATA occupational injuries insurance claims database on farmers’ claims during construction and renovation work for the years 2005 - 2008 was compared with the register of Federation of Accident Insurance Institutions on the construction workers' injuries. In comparing the reasons of the accidents a clear difference was found; poor scaffoldings and ladders are still the main culprits on farm accidents. Farmer interviews were used to assess occupational safety measures on the construction site, occurred injuries and their types, nearmiss situations and the underlying factors which have led to the injuries. Also construction safety deficiencies as well as the direct and indirect costs caused for instance because of the delay in completion of construction project were discussed. Designer interviews aimed to find out how occupational safety and health considerations are taken into account in farm building planning and counseling, and how this experience of the designers should be utilized in order to improve safety at the construction sites on farms. Farmers knew their obligations on occupational safety poorly. The situation was further worsened by the fact that on the site the supervisor tasks were only nominally executed. The

    2014-08-01

    For construction progress monitoring a planned state of the construction at a certain time (as-planed) has to be compared to the actual state (as-built). The as-planed state is derived from a building information model (BIM), which contains the geometry of the building and the construction schedule. In this paper we introduce an approach for the generation of an as-built point cloud by photogrammetry. It is regarded that that images on a construction cannot be taken from everywhere it seems to be necessary. Because of this we use a combination of structure from motion process together with control points to create a scaled point cloud in a consistent coordinate system. Subsequently this point cloud is used for an as-built - as-planed comparison. For that voxels of an octree are marked as occupied, free or unknown by raycasting based on the triangulated points and the camera positions. This allows to identify not existing building parts. For the verification of the existence of building parts a second test based on the points in front and behind the as-planed model planes is performed. The proposed procedure is tested based on an inner city construction site under real conditions.

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.

  20. Prospects for the construction of solar furnaces for industry

    Science.gov (United States)

    La Blanchetais, Ch. H.

    The various techniques and prototype installations employed to absorb and concentrate solar energy for use in applications requiring 100-4000 C temperatures are explored. Mention is made of the Pericles heliostat field and the THEK distributed parabolic concentrator installations, and attention is focused on viable concepts useful for industrial purposes. The Odeillo solar furnace provided design guidelines and requirements for industrial usage. It was found that the reliability of the furnace depends on the annual insolation, that the solar furnaces must be designed to meet specific thermal goals, that simplification and optimization are needed for the orientation and focusing mechanisms, and that solar furnaces are ideally suited for developing nations which experience high levels of insolation. A stepped paraboloid is described for improving the efficiency of a heliostat system, while still employing plane parallel mirrors.

    2012-09-01

    Full Text Available This study involves a financial analysis of 43 publicly listed and large private companies in the building and construction supply chain from 2005 to 2010; straddling the period of the global financial crisis (GFC; and examines the impact of the GFC on the performance of these companies. The construction supply chain was divided into four sectors – material suppliers, construction companies, property developers and real estate investment trusts (REITs. The findings indicate that the impact was minimal for both material suppliers and construction companies, but especially severe for the more leveraged property developers and REITs. Building material suppliers and construction companies have benefitted substantially from the building economic stimulus package provided by the Australian government to mitigate the effects of the GFC. Decreases in the valuation of assets have, to a large extent, reduced the profitability of property developers and REITs during the GFC but these companies have recovered quickly from these adverse conditions to return to a sound financial position by the end of the 2010 financial year. The results will inform investors, managers and construction professionals in devising strategies for prudent financial management and for weathering future financial crises.

    2014-01-01

    The time, quality, and cost are three important but contradictive objectives in a building construction project. It is a tough challenge for project managers to optimize them since they are different parameters. This paper presents a time-cost-quality optimization model that enables managers to optimize multiobjectives. The model is from the project breakdown structure method where task resources in a construction project are divided into a series of activities and further into construction labors, materials, equipment, and administration. The resources utilized in a construction activity would eventually determine its construction time, cost, and quality, and a complex time-cost-quality trade-off model is finally generated based on correlations between construction activities. A genetic algorithm tool is applied in the model to solve the comprehensive nonlinear time-cost-quality problems. Building of a three-storey house is an example to illustrate the implementation of the model, demonstrate its advantages in optimizing trade-off of construction time, cost, and quality, and help make a winning decision in construction practices. The computational time-cost-quality curves in visual graphics from the case study prove traditional cost-time assumptions reasonable and also prove this time-cost-quality trade-off model sophisticated.

    The ITER Tokamak complex consists of Tokamak, diagnostic and tritium buildings. The Tokamak machine is located in the bioshield pit of the Tokamak building. Plant systems are implemented in the three buildings and are strongly interfacing with the Tokamak. The reference baseline (3D) configuration is a set of over 1000 models that today defines in an exhaustive way the overall layout of Tokamak and plant systems, needed for fixing the interfaces and to complete the construction design of the buildings. During the last two years, one of the main ITER challenges was to improve the maturity of the plant systems layout in order to confirm their integration in the building final design and freeze the interface definitions in-between the systems and to the buildings. The propagation of safety requirements in the design of the nuclear building like confinement, fire zoning and radiation shielding is of first priority. A major effort was placed by ITER Organization together with the European Domestic Agency (F4E) and the Architect Engineer as a joint team to fix the interfaces and the loading conditions to buildings. The most demanding systems in terms of interface definition are water cooling, cryogenic, detritiation, vacuum, cable trays and building services. All penetrations through the walls for piping, cables and other equipment have been defined, as well as all temporary openings needed for the installation phase. Project change requests (PCR) impacting the Tokamak complex buildings have been implemented in a tight allocated time schedule. The most demanding change was to implement a new design of the Tokamak basic machine supporting system. The 18 supporting columns of the cryostat (2001 baseline) were replaced at the end of 2012 by a concrete crown and radial concrete ribs linked to the basemat and to the bioshield surrounding the Tokamak. The change was implemented successfully in the building construction design to allow basemat construction phase being performed

    Structural materials in commercial buildings in the United States account for a significant fraction of national energy use, resource consumption, and greenhouse gas (GHG) emissions. Robust decisions for balancing and minimizing these various environmental effects require that structural materials selections follow a life-cycle, systems modeling approach. This report provides a concise overview of the development and use of a new life-cycle assessment (LCA) model for structural materials in U.S. commercial buildings-the Berkeley Lab Building Materials Pathways (B-PATH) model. B-PATH aims to enhance environmental decision-making in the commercial building LCA, design, and planning communities through the following key features: (1) Modeling of discrete technology options in the production, transportation, construction, and end of life processes associated U.S. structural building materials; (2) Modeling of energy supply options for electricity provision and directly combusted fuels across the building life cycle; (3) Comprehensiveness of relevant building mass and energy flows and environmental indicators; (4) Ability to estimate modeling uncertainties through easy creation of different life-cycle technology and energy supply pathways for structural materials; and (5) Encapsulation of the above features in a transparent public use model. The report summarizes literature review findings, methods development, model use, and recommendations for future work in the area of LCA for commercial buildings.

    Full Text Available The industrialised building system (IBS survey has become an essential tool for ensuring the IBS Roadmap (2003 to 2010 meets its goals and target. As part of the process review survey, it also records the trend achievement of Malaysia in the usage of IBS in the building construction industry. The first and second IBS surveys were published in 2003 and 2005, respectively. Afterward, the IBS Roadmap’s midterm review was conducted. The third and the most recent IBS surveys were conducted in 2008 and 2010, respectively. This paper aims to highlight a part of the IBS survey report in 2010, which has been conducted to measure the drivers, barriers and the critical success factors of G7 contractors in adopting IBS construction. G7 is a Construction Industry Development Board contractor grade that can apply tender without limit. The importance of this paper is that it guides the policy and implementation strategy of IBS by G7 contractors. The survey shows that the acceptance, adoption, and deployment of IBS in the Malaysian construction industry are still low and do not address the persisting problems, such as productivity, dependency on foreign workers and high level of construction wastage.

    Li, Jacqueline; Pan, Shu-Yuan; Kim, Hyunook; Linn, Jean H; Chiang, Pen-Chi

    2015-10-01

    As suggested by UNEP, the key to sustainable development is to create a "green economy" which should encapsulate all three sectors: the industry, the people, and the government. Therefore, there is an urgent need to develop and implement the green technologies into the existing facilities, especially in the developing countries. In this study, the role of green supply chains in eco-industrial parks (EIPs) towards a green economy was investigated. The strategies and effective evaluation procedures of the green economy were proposed by assessing the barriers from the perspective of institution, regulation, technology, and finance. In addition, three case studies from iron and steel-making, paper mill and pulping, and petrochemical industries were presented and illustrated for building the green supply chains. For example, in the case of Lin-Hai Industrial Park, a total of 15 efficient green supply chains using waste-to-resources technologies were established by 2012, resulting in an economic benefit of USD 100 million per year. It suggests that the green supply chains should be established to achieve both economic growth and environmental protection. With these successful experiences, building a green supply chain within industrial park should be extensively promoted to make traditional industries around the world being environmentally bearable, economic viable, and social equitable.

  2. Labour Productivity in the New Zealand Construction Industry: A Thorough Investigation

    Directory of Open Access Journals (Sweden)

    John E Tookey

    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.

    Full Text Available Problem statement: Termites are an essential member of the soil ecosystem and are found throughout the world. In their natural environment, they improve soil pH, organic carbon content, water content and porosity by cycling dead organics. They can negatively impact human welfare by causing damage to unprotected timber structures, underground cables, earthen dams, irrigation ditches and farming equipment. Globally, the annual economic cost of termite damage and termite prevention is estimated in billions. In underdeveloped countries data on damage is unavailable and it is difficult to estimate the cost of repair as funds are also not available. This study aimed at addressing termite damage in Zambia as a model underdeveloped country by: (a identifying the injurious species of termites found in the country, (b reviewing the factors affecting the natural durability of wood, (c determining the nature of termite damage to timber, (d determining the most common faulty construction practices which lead to termite entry and infestation in buildings, (e reviewing chemical and biological techniques for prevention of damage to wood and (f developing construction methods that will prevent termite entry to buildings. Approach: Several houses in selected villages, towns and cities in different locations in Zambia were chosen for study (ten houses in each location. The injurious species of termites and natural durability of construction wood were assessed. The damage to timber was evaluated and faulty construction practices that allowed termite entry to buildings were identified. Results: The interior of each house and surrounding area were examined for the presence of termites and termite related damage. Termites were found to gain entry to buildings by a number of paths. These included creating bore holes through walls, crawling through cracks in the foundation and climbing through the roof. Conclusion: To prevent termite entry into the

    The article describes the current state of knowledge and practice in Poland concerning recycling as a method of reuse of chosen groups of waste materials in building industry. The recycling of building scraps is imposed by environmental, economic and technological premises. The issue of usage of sewage residues is becoming a problem of ever -growing gravity as the presence of the increasing number of pernicious contaminants makes their utilization for agricultural purposes more and more limited. The strategies of using waste materials on Polish building sites were analyzed. The analysis of predispositions to salvage for a group of traditional materials, such as: timber, steel, building debris, insulation materials, plastics, and on the example of new materials, such as: artificial light aggregates made by appropriate mixing of siliceous aggregates, glass refuses and sewage residues in order to obtain a commodity which is apt for economic usage also was made in the article. The issue of recycling of waste materials originating from building operations will be presented in the context of the binding home and EU legal regulations. It was proved that the level of recycling of building wastes in Poland is considerably different from one which is achieved in the solid market economies, both in quantity and in assortment. The method of neutralization of building refuses in connection with special waste materials, which are sewage sludge that is presented in the article may be one of the alternative solutions to the problem of recycling of these wastes not only on the Polish scale.

  7. The importance of building construction materials relative to other factors affecting structure survival during wildfire

    Syphard, Alexandra D.; Brennan, Teresa J.; Keeley, Jon E.

    2017-01-01

    Structure loss to wildfire is a serious problem in wildland-urban interface areas across the world. Laboratory experiments suggest that fire-resistant building construction and design could be important for reducing structure destruction, but these need to be evaluated under real wildfire conditions, especially relative to other factors. Using empirical data from destroyed and surviving structures from large wildfires in southern California, we evaluated the relative importance of building construction and structure age compared to other local and landscape-scale variables associated with structure survival. The local-scale analysis showed that window preparation was especially important but, in general, creating defensible space adjacent to the home was as important as building construction. At the landscape scale, structure density and structure age were the two most important factors affecting structure survival, but there was a significant interaction between them. That is, young structure age was most important in higher-density areas where structure survival overall was more likely. On the other hand, newer-construction structures were less likely to survive wildfires at lower density. Here, appropriate defensible space near the structure and accessibility to major roads were important factors. In conclusion, community safety is a multivariate problem that will require a comprehensive solution involving land use planning, fire-safe construction, and property maintenance.

    Full Text Available 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.

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.

    2016-02-01

    This document addresses the use of passive vents as a source of outdoor air in multifamily buildings. The challenges associated with implementing passive vents and the factors affecting performance are outlined. A comprehensive design methodology and quantified performance metrics are provided. Two hypothetical design examples are provided to illustrate the process. This document is intended to be useful to designers, decision-makers, and contractors implementing passive ventilation strategies. It is also intended to be a resource for those responsible for setting high-performance building program requirements, especially pertaining to ventilation and outdoor air. To ensure good indoor air quality, a dedicated source of outdoor air is an integral part of high-performance buildings. Presently, there is a lack of guidance pertaining to the design and installation of passive vents, resulting in poor system performance. This report details the criteria necessary for designing, constructing, and testing passive vent systems to enable them to provide consistent and reliable levels of ventilation air from outdoors.

  4. Application of Microbial Biopolymers as an Alternative Construction Binder for Earth Buildings in Underdeveloped Countries

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Earth buildings are still a common type of residence for one-third of the world’s population. However, these buildings are not durable or resistant against earthquakes and floods, and this amplifies their potential harm to humans. Earthen construction without soil binders (e.g., cement is known to result in poor strength and durability performance of earth buildings. Failure to use construction binders is related to the imbalance in binder prices in different countries. In particular, the price of cement in Africa, Middle East, and Southwest Asia countries is extremely high relative to the global trend of consumer goods and accounts for the limited usage of cement in those regions. Moreover, environmental concerns regarding cement usage have recently risen due to high CO2 emissions. Meanwhile, biopolymers have been introduced as an alternative binder for soil strengthening. Previous studies and feasibility attempts in this area show that the mechanical properties (i.e., compressive strength of biopolymer mixed soil blocks (i.e, both 1% xanthan gum and 1% gellan gum satisfied the international criteria for binders used in earthen structures. Economic and market analyses have demonstrated that the biopolymer binder has high potential as a self-sufficient local construction binder for earth buildings where the usage of ordinary cement is restricted.

    2014-07-10

    In this review, we describe two recently implemented conceptual approaches facilitating the design and deliberate construction of metal–organic frameworks (MOFs), namely supermolecular building block (SBB) and supermolecular building layer (SBL) approaches. Our main objective is to offer an appropriate means to assist/aid chemists and material designers alike to rationally construct desired functional MOF materials, made-to-order MOFs. We introduce the concept of net-coded building units (net-cBUs), where precise embedded geometrical information codes uniquely and matchlessly a selected net, as a compelling route for the rational design of MOFs. This concept is based on employing pre-selected 0-periodic metal–organic polyhedra or 2-periodic metal–organic layers, SBBs or SBLs respectively, as a pathway to access the requisite net-cBUs. In this review, inspired by our success with the original rht-MOF, we extrapolated our strategy to other known MOFs via their deconstruction into more elaborate building units (namely polyhedra or layers) to (i) elucidate the unique relationship between edge-transitive polyhedra or layers and minimal edge-transitive 3-periodic nets, and (ii) illustrate the potential of the SBB and SBL approaches as a rational pathway for the design and construction of 3-periodic MOFs. Using this design strategy, we have also identified several new hypothetical MOFs which are synthetically targetable.

    Exhaust ventilation and corresponding outdoor air strategies are being implemented in high-performance new construction multifamily buildings to meet program or code requirements for improved indoor air quality, but a lack of clear design guidance is resulting in poor performance of these systems despite the best intentions of the programs or standards. CARB's 2014 'Evaluation of Ventilation Strategies in New Construction Multifamily Buildings' consistently demonstrated that commonly used outdoor air strategies are not performing as expected. Of the four strategies evaluated in 2014, the exhaust ventilation system that relied on outdoor air from a pressurized corridor was ruled out as a potential best practice due to its conflict with meeting requirements within most fire codes. Outdoor air that is ducted directly to the apartments was a strategy determined to have the highest likelihood of success, but with higher first costs and operating costs. Outdoor air through space conditioning systems was also determined to have good performance potential, with proper design and execution. The fourth strategy, passive systems, was identified as the least expensive option for providing outdoor air directly to apartments, with respect to both first costs and operating costs. However, little is known about how they actually perform in real-world conditions or how to implement them effectively. Based on the lack of data available on the performance of these low-cost systems and their frequent use in the high-performance building programs that require a provision for outdoor air, this research project sought to further evaluate the performance of passive vents.

    Full Text Available A Green Building Index (GBI is a pioneer in a building grading system to promote sustainability and increase awareness upon environmental issue in Malaysia. The GBI was first established by Malaysia Architect Association (PAM and Association of Consulting Engineers Malaysia (ACEM in February 2009. As a green building contribution on sustainable development and energy efficiency, government has introduced incentives to parties who involve in obtaining Green Building Index Certificate to inculcate vgreen technology. The present paper articulates various categories of incentives introduced by government for construction key players in Malaysia and compare those incentives implies worldwide including countries such as United States, United Kingdom, Australia and Singapore. The incentives are categories into three; financial incentives, fiscal incentives and structure incentives. In a case of financial incentives the financial grants, loans, fund, vouchers, rebates and etc. attract building developers to adopt green elements and apply for certification in their new building project. Obviously, most developers more engrossed to the incentives which has a direct impact on the project financial cash flow. Fiscal incentive however is a privilege by the government, in term of tax exemption granted to respective green building project. Structural incentives are much common incentives offered by government because it would not require expenditure of fund and not reduce the income of city and county. By comparing few successful model of incentives by several countries, the present research reveals that the structure of incentives for green building in Malaysia should have more focused on structural incentive especially those involves technical support, expedited building permit and Gross Floor Area (GFA equivalent incentive scheme.

    Time in infrastructure construction projects has always been a fundamental issue as early as from the inception of a project, during the construction process and often after the completion and delivery. In a typical construction contract time related matters such as the completion date and possible delays are among the most important issues that are dealt with by the contract provisions. In the event of delay there are usually provisions for extension of time award to the contractor with possible reimbursement for the extra cost and expenses caused by this extension of time to the contract duration. In the case the contractor is not entitled to extension of time, the owner will be possibly entitled to amounts as compensation for the time prohibited from using his development. Even in the event of completion within the time agreed, under certain circumstances a contractor may have claims for reimbursement for extra costs incurred due to induced acceleration measures he had to take in order to mitigate disruption effects caused to the progress of the works by the owner or his representatives. Depending on the size of the project and the agreement amount, these reimbursement sums may be extremely high. Therefore innovative methods with the exploitation of new technologies for effective project management for the avoidance of delays, delay analysis and mitigation measures are essential; moreover, methods for collecting efficiently information during the construction process so that disputes regarding time are avoided or resolved in a quick and fair manner are required. This paper explores the state of art for existing use of Building Information Modelling (BIM) and Unmanned Aerial Vehicles (UAV) technologies in the construction industry in general. Moreover the paper considers the prospect of using BIM technology in conjunction with the use of UAV technology for efficient and accurate as-built data collection and illustration of the works progress during an

    Glezil, Dorothy

    NEHRP's Provisions today currently governing conventional seismic resistant design. These provisions, though they ensure the life-safety of building occupants, extensive damage and economic losses may still occur in the structures. This minimum performance can be enhanced using the Performance-Based Earthquake Engineering methodology and passive control systems like base isolation and energy dissipation systems. Even though these technologies and the PBEE methodology are effective reducing economic losses and fatalities during earthquakes, getting them implemented into seismic resistant design has been challenging. One of the many barriers to their implementation has been their upfront costs. The green building community has faced some of the same challenges that the high performance seismic design community currently faces. The goal of this thesis is to draw on the success of the green building industry to provide recommendations that may be used overcome the barriers that high performance seismic design (HPSD) is currently facing.

    Recently in Korea, the treatment of asbestos-containing materials (ACM) in building has emerged as one of the most important environmental health issues. This study was conducted to identify the distribution and characteristics of ACM and airborne asbestos concentrations in industrial buildings in Korea. A total of 1285 presumed asbestos-containing material (PACM) samples were collected from 80 workplaces across the nation, and 40% of the PACMs contained more than 1% of asbestos. Overall, 94% of the surveyed workplaces contained ACM. The distribution of ACM did not show a significant difference by region, employment size, or industry. The total ACM area in the buildings surveyed was 436,710 m2. Ceiling tile ACM accounted for 61% (267,093 m2) of the total ACM area, followed by roof ACM (32%), surfacing ACM (6.1%), and thermal system insulation (TSI). In terms of asbestos type, 98% of total ACM was chrysotile, while crocidolite was not detected. A comparison of building material types showed that the material with the highest priority for regular management is ceiling tile, followed by roof, TSI, and surfacing material. The average airborne concentration of asbestos sampled without disturbing in-place ACM was 0.0028 fibers/cc by PCM, with all measurements below the standard of recommendation for indoor air quality in Korea (0.01 fibers/cc).

    2012-02-01

    Full Text Available The search for energy efficient construction solutions is still pending in the agro-food industry, in which a large amount of energy is often consumed unnecessarily when storing products. The main objective of this research is to promote high energy efficiency built environments, which aim to reduce energy consumption in this sector. We analyze the suitability of using the thermal inertia of the ground to provide an adequate environment for the storage and conservation of agro-food products. This research compares different construction solutions based on the use of ground thermal properties, analyzing their effectiveness to decrease annual outdoor variations and provide adequate indoor conditions. The analysis undertaken is based on over five million pieces of data, obtained from an uninterrupted four year monitoring process of various constructions with different levels of thermal mass, ranging from high volume constructions to others lacking this resource. It has been proven that constructive solutions based on the use of ground thermal inertia are more effective than other solutions when reducing the effects of outdoor conditions, even when these have air conditioning systems. It is possible to reach optimal conditions to preserve agro-food products such as wine, with a good design and an adequate amount of terrain, without having to use air conditioning systems. The results of this investigation could be of great use to the agro-food industry, becoming a reference when it comes to the design of energy efficient constructions.

    Full Text Available Delay and loss of payment is a serious problem in the construction industry of many countries. These affect the cash flow of contractors which is critical to meeting their financial obligations. Payment defaults by the principal leads to insolvency of contractors and in turn other parts of the project chain. In recognition of some of these problems, most countries have established payment-specific construction industry legislation and other contractual measures to mitigate the problems, but nevertheless the problem persists. In this context, the paper examines the nature of payment problems in the construction industry in New Zealand. It is part of a larger study, that seeks solutions to payment losses in the construction industry.The study uses two approaches; an analysis of liquidators’ reports, and an analysis of court cases involving payment disputes to determine the magnitude of payment problems on construction parties. The findings are presented using simple descriptive and interpretive analyses. The study finds that trade creditors are impacted negatively (payment delays and losses by the liquidation of property developers, general construction and construction trade companies. 75% of trade creditors are unable to be paid fully by these categories of construction companies after liquidation proceedings. Liquidation proceedings take an average 18 months before they are finalised. The analysis of court cases found that 80% of payment disputes are between principals and contractors; with considerably significant percentage of disputes resulting in outright loss of payments. Only 40% of the cases are successful, in which case claimants are able to fully recover the amount in dispute. Payment losses are more prevalent in liquidation than delays and unlike in legal disputes, there is no security for those losses. The study finds that construction parties use remedies contained in the security of payment provisions within standard conditions

The study finds that trade creditors are impacted negatively (payment delays and losses by the liquidation of property developers, general construction and construction trade companies. 75% of trade creditors are unable to be paid fully by these categories of construction companies after liquidation proceedings. Liquidation proceedings take an average 18 months before they could be finalised. The analysis of court cases found that 80% of payment disputes are between principals and contractors; with considerably significant percentage of disputes resulting in outright loss of payments. Only 40% of the cases are successful, in which case claimants are able to fully recover the amount in dispute. Payment losses are more prevalent in liquidation than delays and unlike in legal disputes, there is no security for those losses. The study finds that construction parties use remedies contained in the security of payment provisions within standard

    Full Text Available ‘Working’ is regarded as a humanitarian effort; requiring respect due to ‘labour is not a commodity’ principle. Organizations such as ILO have been established to set standards for labour. Despite there are different applications, the system consists of employee unions and employer associations and social partners in Europe. The EU monitors member states where applications differ due to economic, politic and industrial backgrounds. In the industrial relations, VET Systems are crucial. Learning is stil either craft or training-based linked to employment policies, cultures and economic profiles. The construction industry urges for collective agreements due to its labour nature; since the industry demands for variety of professions within organizational chains. The mobility requiring security, temporary building process coping with deadlines, climate, dangerous labour in addition to specific demands for particular skills and unique production chains require special regulations. Therefore, bargaining leads to labour rights and workers’ training to achieve more qualified products or safety reasons; as well as a tool to increase economical activity and revise industry’s image. The Netherlands and Turkey are compared to analyse industry’s prosperity in EU.

    Full Text Available Among the recent data mining techniques available, the boosting approach has attracted a great deal of attention because of its effective learning algorithm and strong boundaries in terms of its generalization performance. However, the boosting approach has yet to be used in regression problems within the construction domain, including cost estimations, but has been actively utilized in other domains. Therefore, a boosting regression tree (BRT is applied to cost estimations at the early stage of a construction project to examine the applicability of the boosting approach to a regression problem within the construction domain. To evaluate the performance of the BRT model, its performance was compared with that of a neural network (NN model, which has been proven to have a high performance in cost estimation domains. The BRT model has shown results similar to those of NN model using 234 actual cost datasets of a building construction project. In addition, the BRT model can provide additional information such as the importance plot and structure model, which can support estimators in comprehending the decision making process. Consequently, the boosting approach has potential applicability in preliminary cost estimations in a building construction project.

    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.

    Construction and demolition waste continues to sharply increase in step with the economic growth of less developed countries. Though the construction industry is large, it is composed of small firms with individual waste management practices, often leading to the deleterious environmental outcomes. Quantifying construction and demolition waste generation allows policy makers and stakeholders to understand the true internal and external costs of construction, providing a necessary foundation for waste management planning that may overcome deleterious environmental outcomes and may be both economically and environmentally optimal. This study offers a theoretical method for estimating the construction and demolition project waste generation rate by utilising available data, including waste disposal truck size and number, and waste volume and composition. This method is proposed as a less burdensome and more broadly applicable alternative, in contrast to waste estimation by on-site hand sorting and weighing. The developed method is applied to 11 projects across Malaysia as the case study. This study quantifies waste generation rate and illustrates the construction method in influencing the waste generation rate, estimating that the conventional construction method has a waste generation rate of 9.88 t 100 m(-2), the mixed-construction method has a waste generation rate of 3.29 t 100 m(-2), and demolition projects have a waste generation rate of 104.28 t 100 m(-2).

    1999-11-01

    Detailed calculation methods for evaluating heat loss through building envelope constructions have been investigated in the project. First a detailed description of the calculation methods, i.e. both calculation programs and guidelines, for calculating typical thermal bridges in building envelope constructions is given. After this a validation of both programs and guidelines is presented. The validation is performed by comparing calculated U-values with Guarded Hot Box measurements. The last part of the thesis discusses the possibilities of utilising the results of detailed calculations in more operational and applicable projecting tools, e.g. thermal bridge catalogues or U-value tables. A calculation of a one-family house is described in detail. All the important thermal bridges are covered by the detailed calculations, and from the analysis both the methods of the revised Danish standard and the European standards are evaluated. It is shown that the Danish standard is both reliable and accurate. All calculations have shown a very good compliance with corresponding measurments and the analysis has shown that a direct translation from physical construction to mathematical description can be used. The detailed methods of calculating are excellent for the development of new constructions but not very operational for projecting buildings. Due to the time-consuming modelling and in some cases also calculations, there is a need for developing simpler methods to utilise the results from detailed calculations. An investigation concerning the possibilities of developing different tools to simplify the projecting calculations for new buildings has been carried out. It is concluded that there is a need for a further enhancement of the existing methods, e.g. U-value catalogues. (LN) EFP-96. 58 refs.

    Full Text Available Organisations are increasingly focusing on building long-term relationships with customers, thereby increasing their probability for success by offering customers higher levels of satisfaction, increasing customer loyalty, and ultimately retaining customers. Airlines in particular can benefit from retaining customers as the airline industry is characterised by fierce competition and many airlines are finding it difficult to survive against the backdrop of enormous challenges in the past decade, including the significant decline in demand for air travel together with rising costs and the worldwide economic downturn. This study investigates the effect which a strategy by airlines of building relationships with customers has on customer satisfaction, loyalty, and ultimately customer retention. The effect of service failures on customers' relationships with airlines are also considered as a negative experience could results in customers defecting to competitors. A questionnaire, comprising six sections, was specifically compiled to determine customer retention in the South African domestic passenger airline industry. Data were collected by trained fieldworkers from OR Tambo International Airport by means of a non-probability convenience sampling method from 324 passengers flying with the various domestic airlines. Findings indicate that most respondents were satisfied with the airlines' overall service; respondents who formed relationships with domestic airlines were more loyal toward the airlines; and the relationships of respondents who were satisfied with airlines' service recovery efforts were either strengthened or unchanged. The findings from this study support findings from international studies by providing a unique South African perspective on the effect of a strategy of building relationships with customers on their satisfaction, loyalty and ultimately retention. It can therefore be recommended that the organisations competing in the South

    2011-01-01

    Four different kinds of materials (feldspar, gypsum, clay and kaolin) commonly used in building construction and industry in Serbia were analyzed for their natural radioactivity, using gamma spectrometry. The radium equivalent activity, Ra(eq), the absorbed dose rate, D, the annual effective dose, D(E), and the external hazard index, H(ex), were evaluated to assess the radiation hazard for people living in dwellings made of the materials studied. The radium equivalent activities calculated in all samples are lower than the maximum admissible value 370 Bq kg(-1) set in the UNSCEAR report. The absorbed dose rate in air was found to vary from 0.02 to 0.19 μGy h(-1). Considering the fact that the average gamma dose rate indoors in Europe is 0.07 μGy h(-1), gamma dose rate calculated for feldspar, clay and kaolin samples exceed this limit. The obtained results for annual effective dose exceed limits of 0.41 mSv for feldspar, clay and kaolin samples. If the H(ex) exceeds unity, we might conclude that the potential external dose(s) to exposed individual(s) will exceed the acceptable level, and some action may be required. The obtained values of H(ex) are lower than unity for all investigated samples. All samples were measured immediately after preparation, except 10 samples of feldspar, because a comparative analysis were made between 215 samples which were measured immediately after preparation and 10 samples which were measured after radioactive equilibrium was reached in order to detect differences in the obtained concentrations.

    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.

    Full Text Available The paper deals with the seismic retrofit of a multiple building structure belonging to the Hospital Centre of Avellino (Italy. At first, the paper presents the preliminary investigations, the in situ measurements and laboratory tests, and the seismic assessment of the existing fixed-base structures. Having studied different strategies, base isolation proved to be the more appropriate, also for the possibility offered by the geometry of the building to easily create an isolation interface at the ground level. The paper presents the design project, the construction process, and the details of the isolation intervention. Some specific issues of base isolation for seismic retrofitting of multiple building structures were lightened. Finally, the seismic assessment of the base-isolated building was carried out. The seismic response was evaluated through nonlinear time-history analysis, using the well-known Bouc-Wen model as the constitutive law of the isolation bearings. For reliable dynamic analyses, a suite of natural accelerograms compatible with acceleration spectra of Italian Code was first selected and then applied along both horizontal directions. The results were finally used to address some of the critical issues of the seismic response of the base-isolated multiple building structure: accidental torsional effects and potential poundings during strong earthquakes.

The method was applied to a safety analysis during a continuous and dynamic simulation of the entire construction process.The results show that the organic combination of the BIM, 4D technology, construction simulation, and safety analysis of time-dependent structures is feasible and practical. This research also lays a foundation for further researches on building lifecycle management by combining architectural design, structure analy-sis, and construction management.

    The increase in the share of renewable energy sources together with the emphasis on the need for energy security bring to a spotlight the field of trigeneration autonomous microsystems, as a solution to cover the energy consumptions, not only for isolated industrial buildings, but also for industrial buildings located in urban areas. The use of solar energy for cooling has been taken into account to offer a cooling comfort in the building. Cooling and air- conditioned production are current applications promoting the use of solar energy technologies. Solar cooling systems can be classified, depending on the used energy, in electrical systems using mechanical compression chillers and systems using thermal compression by absorption or adsorption. This comparative study presents the main strengths and weaknesses of solar cooling obtained: i) through the transformation of heat resulted from thermal solar panels combined with adsorption chillers, and ii) through the multiple conversion of electricity - photovoltaic panels - battery - inverter - combined with mechanical compression chillers. Both solutions are analyzed from the standpoints of energy efficiency, dynamic performances (demand response), and costs sizes. At the end of the paper, experimental results obtained in the climatic condition of Galafi city, Romania, are presented.

    Construction is a heavy manual industry where working into later life can be a challenge. An interview study was conducted to explore workers' understanding of their health at work and ways of making their jobs easier, safer or more comfortable. Using purposive sampling, 80 trades' workers were selected from construction sites in the UK. The Nordic Musculoskeletal Questionnaire and Work Ability Index were used to explore aches and pains and reducing strain on the body. A high prevalence of symptoms was reported and ratings of work ability were high. Workers were aware of the physical demands of their work and had over 250 ideas around health and wellbeing e.g. rucksacks for tools, bespoke benches, adapting PPE, and higher cost solutions e.g. mechanical lifting aids. Engagement of the workforce should be encouraged and feed into change processes in the industry to enable all workers stay fit for work for longer.

    In 2002, the United States Department of Energy (USDOE) published an energy efficiency assessment of U.S. industrial sector motor systems titled United States Industrial Electric Motor Systems Market Opportunities Assessment. The assessment advanced motor system efficiency by providing a greater understanding of the energy consumption, use characteristics, and energy efficiency improvement potential of industrial sector motor systems in the U.S. Since 2002, regulations such as Minimum Energy Performance Standards, cost reductions for motor system components such as variable frequency drives, system-integrated motor-driven equipment, and awareness programs for motor system energy efficiency have changed the landscape of U.S. motor system energy consumption. To capture the new landscape, the USDOE has initiated a three-year Motor System Market Assessment (MSMA), led by Lawrence Berkeley National Laboratory (LBNL). The MSMA will assess the energy consumption, operational and maintenance characteristics, and efficiency improvement opportunity of U.S. industrial sector and commercial building motor systems. As part of the MSMA, a significant effort is currently underway to conduct field assessments of motor systems from a sample of facilities representative of U.S. commercial and industrial motor system energy consumption. The Field Assessment Plan used for these assessments builds on recent LBNL research presented at EEMODS 2011 and EEMODS 2013 using methods for characterizing and determining regional motor system energy efficiency opportunities. This paper provides an update on the development and progress of the MSMA, focusing on the Field Assessment Plan and the framework for assessing the global supply chain for emerging motors and drive technologies.

  18. 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.

    Nowadays, construction industry particularly in Malaysia struggle in achieving status of eminent time management for construction project. Project managers have a great responsibility to keep the project success under time of project completion. However, studies shows that delays especially in Malaysian construction industry still unresolved due to weakness in managing the project. In addition, quality of time management on construction projects is generally poor. Due to the progressively extended delays issue, time performance becomes an important subject to be explored to investigate delay factors. The method of this study is review of literature towards issues in construction industry which affecting time performance of project in general by focusing towards process involved for project management. Based on study, it was found that knowledge, commitment, cooperation are the main criteria as an overall to manage the project into a smooth process during project execution until completion. It can be concluded that, the strength between project manager and team members in these main criteria while conducting the project towards good time performance is highly needed. However, there is lack of establishment towards factors of poor time performance which strongly related with project management. Hence, this study has been conducted to establish factors of poor time performance and its relations with project management.

    The Research Utilization Program was conceived as a far-reaching means for managing the interactions of the private sector and the federal research sector as they deal with energy conservation in buildings. The program emphasizes a private-public partnership in planning a research agenda and in applying the results of ongoing and completed research. The results of this task support the hypothesis that the transfer of R and D results to the buildings industry can be accomplished more efficiently and quickly by a systematic approach to technology transfer. This systematic approach involves targeting decision makers, assessing research and information needs, properly formating information, and then transmitting the information through trusted channels. The purpose of this report is to introduce elements of a market-oriented knowledge base, which would be useful to the Building Systems Division, the Office of Buildings and Community Systems and their associated laboratories in managing a private-public research partnership on a rational systematic basis. This report presents conceptual models and data bases that can be used in formulating a technology transfer strategy and in planning technology transfer programs.

    Several reviews in the past decade have heralded the benefits of embracing high-throughput sequencing technologies to inform conservation policy and the management of threatened species, but few have offered practical advice on how to expedite the transition from conservation genetics to conservation genomics. Here, we argue that an effective and efficient way to navigate this transition is to capitalize on emerging synergies between conservation genetics and primary industry (e.g., agriculture, fisheries, forestry and horticulture). Here, we demonstrate how building strong relationships between conservation geneticists and primary industry scientists is leading to mutually-beneficial outcomes for both disciplines. Based on our collective experience as collaborative New Zealand-based scientists, we also provide insight for forging these cross-sector relationships.

    2009-01-01

    Full Text Available The use of IBS (Industrialised Building System has attracted a lot of countries like Singapore, Sweden, Germany, Japan and the United Kingdom. This system can replace the conventional building system which is labour oriented. However, since the first project of IBS in year 1964 till today, IBS in Malaysia is not well accepted by the construction parties because of failure to adequately deal with risks in the IBS projects. To address this matter, this study had identified the risks faced by contractor in IBS construction projects. The risk identification techniques used were brainstorming, analysis of journal and conference papers and discussion with practitioners and data were collected by a questionnaire survey on contractors. It was found that there are twelve major risks in construction using IBS which are; acts of God, change in work and defective design, changes in government regulation, contractor competence, delayed payment and resolving contractual issues, financial failure-any party, labour and equipment productivity, labour, equipment and material availability, quality of work, safety, site access/right of way and suppliers/manufacturers poor performance. Therefore, it is hoped that the finding of this research could assist Malaysian contractors in making risk management planning besides improving decisions making to achieve project.

  6. Analysis, Design, and Construction of a Base-Isolated Multiple Building Structure

    2014-01-01

    Full Text Available The analysis and design of a multiple residential building, seismically protected by a base isolation system incorporating double friction pendulum sliders as protective devices, are presented in the paper. The building, situated in the suburban area of Florence, is composed of four independent reinforced concrete framed structures, mutually separated by three thermal expansion joints. The plan is L-shaped, with dimensions of about 75 m in the longitudinal direction and about 30 m along the longest side of the transversal direction. These characteristics identify the structure as the largest example of a base-isolated “artificial ground” ever built in Italy. The base isolation solution guarantees lower costs, a much greater performance, and a finer architectural look, as compared to a conventional fixed-base antiseismic design. The characteristics of the building and the isolators, the mechanical properties and the experimental characterization campaign and preliminary sizing carried out on the latter, and the nonlinear time-history design and performance assessment analyses developed on the base isolated building are reported in this paper, along with details about the installation of the isolators and the plants and highlights of the construction works.

    The main objectives of this study were to identify the most problematic postures in hammering tasks performed at building construction sites through application of the computerized OWAS method, and to develop recommendations for improvement of working method and workplaces. Eighteen construction workers, with mean age of 41.6, from three construction companies participated in the field study. The hammering tasks observed during the two-month period included roof boarding, concrete form preparation, clamping support braces, assembling roof frames, roof joisting, shelter form preparation, and fixing fork clamps. Three different types of hammer, including a small Fiskar's hammer, a Fiskar's construction hammer, and a Rocket hammer, were used by the workers. Of all the observations, poor working postures were observed most frequently in roof joisting (12.4% of all observations within the task), followed by concrete form preparation (8.6%), and construction of frames for the roof (7.5%). Overall, out of 593 different postures analysed, a total of 7.8% of postures adopted by the workers during various hammering tasks were classified into OWAS categories III or IV, indicating that these postures should be corrected either soon or immediately. The computerized OWAS method for postural data analysis proved to be a very useful way to reduce postural load of dynamic hammering tasks, and allowed for efficient application of the original OWAS method.

    Full Text Available Problems associated with fragmentation in the traditional construction process, such as isolation of professionals, lack of co-ordination between design and construction, and the sequential manner of its processes, has impacted on construction performance leading to a lack of integration, wastage, low productivity and efficiency. Integrated team practice is perceived as paramount. Unfortunately, there has a limitation of study focus on the dimension of fully integrated team especially for Malaysian Industrialised Building System (IBS projects. Accordingly, this research paper explores and identifies the dimension of fully integrated team from the traditional approach and conduct a validation process for implementing it in Malaysian IBS projects. The research presented uses interviews case study to obtain qualitative data. It was found that the dimension of fully integrated team from the traditional construction process could apply to the Malaysian IBS projects. Suggestions on how an integrated team practice in IBS design and construction process in order to minimise the fragmentation gaps will be concluded.

    The US Department of Energy's Office (DOE) of Geothermal Technologies conducted its annual Program Review XVII in Berkeley, California, on May 18--20, 1999. The theme this year was "Building on 25 Years of Geothermal Partnership with Industry". In 1974, Congress enacted Public Law 93-410 which sanctioned the Geothermal Energy Coordination and Management Project, the Federal Government's initial partnering with the US geothermal industry. The annual program review provides a forum to foster this federal partnership with the US geothermal industry through the presentation of DOE-funded research papers from leaders in the field, speakers who are prominent in the industry, topical panel discussions and workshops, planning sessions, and the opportunity to exchange ideas. Speakers and researchers from both industry and DOE presented an annual update on research in progress, discussed changes in the environment and deregulated energy market, and exchanged ideas to refine the DOE Strategic Plan for research and development of geothermal resources in the new century. A panel discussion on Climate Change and environmental issues and regulations provided insight into the opportunities and challenges that geothermal project developers encounter. This year, a pilot peer review process was integrated with the program review. A team of geothermal industry experts were asked to evaluate the research in progress that was presented. The evaluation was based on the Government Performance and Results Act (GPRA) criteria and the goals and objectives of the Geothermal Program as set forth in the Strategic Plan. Despite the short timeframe and cursory guidance provided to both the principle investigators and the peer reviewers, the pilot process was successful. Based on post review comments by both presenters and reviewers, the process will be refined for next year's program review.

    Full Text Available The present paper is aiming to provide an actual state of the development of non autoclaved Agro-Industrial aerated concrete by using multiple ashes as improvement of thermal behavior for building. The feasibility of Agro-Industrial wastes as lightweight concrete by utilizing the Palm Oil Fuel Ash (POFA as binder replacement and bottom ash as fine aggregate was investigated in this paper. Portland cement, bottom ash, aluminum powder and lime (Ca(OH2 were used in this study. The POFA was used to replace Portland cement and Hydrated Lime at 0%, 5%, 10% and 15% by weight and aluminum powder was added at 0.75% dry weight in order to form bubbles. The compressive strength, water absorption, porosity and the thermal conductivity test were carried out after the concrete were water cured for 7 days and later being exposed to the air and water until 28days. The results show that the 20% replacements give the optimum strength of 7.143MPa and 30% give the best thermal conductivity with 0.48W/mK. Hence, this study aim, was to develop an agro-industrial aerated concrete good in insulation but having an optimum strength. Hence, it has been found that the more the percentage of POFA is added the lower the thermal conductivity since the pore structure is increasing and by the optimization done, 30% replacement has been chosen as the best mix design for Agro-Industrial Aerated Concrete.

    BIM is targeted at providing information about the entire building and a complete set of design documents and data stored in an integrated database. In this paper, we study the use of BIM in two life-cycle construction projects in Kuopio, Finland during 2011. The analysis of uses of BIM and their main problems will constitute a foundation for an intervention. We will focus on the following questions: (1) How different partners use the composite BIM model? (2) What are the major contradictions or problems in the BIM use? The preliminary findings reported in this study show that BIM has been adopted quite generally to design use but the old ways of collaboration seem to prevail, especially between designers and between designers and building sites. BIM has provided new means and demands for collaboration but expansive uses of BIM for providing new interactive processes across professional fields have not much come true.

    The development of efficient tools for genetic modification of industrial yeast strains is one of the challenges that face the use of recombinant cells in industrial processes. In this study, we examine how the construction of two complementary integrative vectors can fulfill the major requirements of industrial recombinant yeast strains: the use of lactose assimilation genes as a food-grade yeast selection marker, and a system of integration that does not leave hazardous genes in the host genome and involves minimal interference in the yeast physiology. The pFB plasmid set was constructed to co-integrate both LAC4-based and LAC12-based cassettes into the ribosomal DNA (rDNA) locus to allow yeast cells to be selected in lactose medium. This phenotype can also be used to trace the recombinant cells in the environment by simply being plated on X-gal medium. The excisable trait of the LAC12 marker allows the introduction of many different heterologous genes, and makes it possible to introduce a complete heterologous metabolic pathway. The cloned heterologous genes can be highly expressed under the strong and constitutive TPI1 gene promoter, which can be exchanged for easy digestion of enzymes if necessary. This platform was introduced into Saccharomyces cerevisiae JP1 industrial strain where a recombinant with high stability of markers was produced without any change in the yeast physiology. Thus, it proved to be an efficient tool for the genetic modification of industrial strains.

    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
