    2014-07-01

    Full Text Available Construction industry is facing many problems in terms of construction waste, quality, environment, durability, safety and higher construction cost. Adoption of prefabrication is a possible solution to such problems. Accordingly, there is a need to study the prospects that would stimulate the appropriate discussion of the suitability of prefabrication and other construction methods for concrete buildings. Therefore, this study investigates the significance of advantages in adopting prefabrication along with hindrances through questionnaire survey. The data has been analyzed using RIW (Relative Importance Weight method as a MCDM approach. The results depict that main advantages of prefabrication are ?Shorter construction time? and ?Less construction site waste?. The top hindrances in adopting prefabrication as identified in this study are: ?Higher initial construction cost? and ?Inflexible for design changes?. Based on the survey results and apparent progress in the adoption of prefabrication around the world, it is concluded that the use of prefabrication is likely to increase in developing countries like Pakistan

    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.

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

    Pofale, Arun D; Nadeem, Mohammed

    2012-01-01

    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.

  15. Material Efficiency of Building Construction

    Directory of Open Access Journals (Sweden)

    Antti Ruuska

    2014-07-01

    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.

  18. Building an industry; building an economy

    International Nuclear Information System (INIS)

    This presentation provided an outline of oil and gas activity in the province, with a focus on the social and economic benefits provided to the province by the major oil and gas plays of Hibernia, Terra Nova and White Rose. Between 1999 and 2004, oil and gas activity contributed to an 18.4 per cent rise in the gross domestic product (GDP) of Newfoundland. Personal incomes rose by 5.9 per cent, and retail sales achieved an increase of 5.1 per cent. The population of the province has increased by 9000, and the unemployment rate has dropped by 2.3 per cent. Infrastructure additions provided by the oil and gas sector include construction sites; shipyards; a sub-sea fabrication centre; a trans-shipment terminal; a pipeyard, warehouse and operations centre; and a supply base and heliport. The petroleum industry has also contributed significantly to a variety of training and research facilities in the province. Oil revenues continue to accrue to the Newfoundland government, and economic diversification has improved in the region. Despite these contributions, the petroleum industry is often seen as transient and tangential to the economy. The industry is viewed as a revenue source, and its activities are seen as being of short duration. It was suggested that a wider recognition of the range, scope and scale of benefits provided by the industry are needed to address public misperceptions. Efforts must be made by the province to help the industry grow, and a wider recognition of diversification and sustainability must be achieved. refs., tabs., figs

    Many areas of knowledge converge in the building industry and therefore research in this field necessarily involves an interdisciplinary approach. Effective research requires strong relations between a broad variety of scientific and technological domains and more conventional construction or craft processes, while also considering advanced management processes, where all the main actors permanently interact. This publication takes an interdisciplinary approach grouping various studies on the building industry chosen from among the works presented for the 2nd International Conference on Construction and Building Research. The papers examine aspects of materials and building systems; construction technology; energy and sustainability; construction management; heritage, refurbishment and conservation. The information contained within these pages may be of interest to researchers and practitioners in construction and building activities from the academic sphere, as well as public and private sectors.

    Modern materials and construction solutions draw more and more attention to ecology and building certification. Among the criteria appearing in revitalization, an important element is bringing plants back into heavily urbanized areas. In its natural form, this is not possible to carry out everywhere, often requiring large amounts of space. Nowadays, however, there are a number of green roofs and green wall systems, allowing "greener" construction without making significant changes in the urban environment. The article includes a presentation and analysis of selected solutions of biological surfaces known as green roofs and green walls, specifying various solutions and their most important features. The case study focuses primarily on material and design solutions, as well as the potential benefits, risks and limitations in their use. Plants structures on the surfaces of vertical and horizontal partitions continue to be a very interesting alternative to take into account when applying for grants, such as LEED or BREEAM certificates.

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

  10. Sustainable Entrepreneurship in the Dutch Construction Industry

    Directory of Open Access Journals (Sweden)

    Rosalinde J.A. Klein Woolthuis

    2010-02-01

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

  11. Data Policy Construction Set - Building Blocks from Childhood Constructions

    2016-04-01

    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

    Full Text Available Problem statement: As we may not be aware that the coastal construction is different from inland construction. Building in a coastal environment is different from building in an inland area. In general, buildings in coastal areas must be designed and built to withstand higher loads due to its more extreme conditions. Nowadays, the issue of global warming, uncertainty of global weather and the climate change effect indirectly creating the coastal area with much more expose to extreme condition. Formulate initial guidelines with certain degree of details how coastal construction requirements are different from those for inland construction. Approach: Due to the exposure to higher loads and extreme conditions, these structures in coastal areas will cost more to design, construct, maintain, repair and insure. Proper and right usage of building materials including electrical and mechanical equipments, are crucial in order to minimize damage. Nowadays, the issue of global warming, uncertainty of global weather and the climate change effect indirectly creating the coastal area with much more expose to extreme condition. Feedback has been gathered from the government local engineers who are doing the management of the Government’s local buildings located along the coastal area of Peninsular Malaysia. Data findings through research method, discussion with the suppliers and discussion with coastal buildings maintenance crews also has been done. Results: The research finding discus the specific characteristics that makes for successful coastal buildings focusing in tropical region. Conclusion: We must accept on the idea of building in coastal areas will require more maintenance and upkeep. By having proper coastal building guideline may create more positive awareness in constructing better management coastal buildings and can save time and money to maintain the said structures.

    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 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. The findings of the present study revealed invaluable indications to the construction managers especially in improving the construction workers’ attitude towards safety, health and environment and hence good safety culture in the building construction industries.

    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 It has been observed that the construction industry is one of the notorious industry having higher rate of fatalities and injuries. Resulting in higher financial losses and work hour losses, which are normally faced by this industry due to occuptional accidents. Construction industry has the highest occupational accidents rate recorded throughout the world after agriculture industry. The construction work site is often a busy place having an incredibly high account of activities taking place, where everyone is moving in frenzy having particular task assigned. In such an environment, occupational accidents do occur. This paper gives information about different types of occupational accidents & their causes in the construction industry of Pakistan. A survey has been carried out to identify the types of occupational accidents often occur at construction site. The impact of each occupational accident has also been identified. The input from the different stakeholders involved on the work site was analyzed using RIW (Relative Importance Weight method. The findings of this research show that ?fall from elevation, electrocution from building power and snake bite? are the frequent occupational accidents occur within the work site where as ?fall from elevation, struck by, snake bite and electrocution from faulty tool? are the occupational accident with high impact within the construction industry of Pakistan. The results also shows the final ranking of the accidents based on higher frequency and higher impact. Poor Management, Human Element and Poor Site Condition are found as the root causes leading to such occupational accidents. Hence, this paper

    It is difficult to realize the transformation from traditional economy industrial system to circular economy industrial system.Regarding primary raw materials as the indicators,the industrial system has been specified according to the divergence among the indicators and the circular utilization modes.In comparison with the association among industrial systems,the relationship among industrial sub-systems is named as industrial cross-linking in this paper.The industrial system which could completely utilize and recycle the indicators should be increased and strengthened,and the circular economy industrial system with complete industrial association and industrial cross-linking should also be constructed.Taking the development of circular agricultural system basing on the traditional agricultural system as an example,the traditional agricultural products are regarded as the indicators which have been divided into foodstuff and crop straws which are used to produce food and articlesfor use,like fertilizer,energy and papers etc.The way to construct the circular agricultural industrial system is to increase the industrial systems that could utilize the products generated from crop straws,feces and other castoffs and transform the wastewater and other trucks into environmental friendly products.It has also been pointed out that the construction of circular economy industrial system is conducive to the foundation of circular industrial economics and the establishment of the construction layout of circular economy and the application schemes.Suggestions to the theoretical and practical work of the next step have also been brought forward in this paper.

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

    The goal of this research is to deliver handbooks to owners of buildings, architects and engineers. These handbooks will provide the concerned groups with relevant findings on energy conservation in buildings in a clearly arranged form. The first part will describe all requirements to be fulfilled in buildings. Alternative construction possibilities will be given together with the corresponding physical data. Influencing factors resulting from the different building usages, the different shapes and orientations will be collected and classified by types of buildings. In addition, physiological, meteorological and environmental values will be considered. The second part covers a summary of the most favorable systems and components which will be able to fulfill energy conservation functions (i.e., the requirements out of part I). They will be sub-divided into heating, ventilation, air-conditioning, lighting, warm water supply, heat recovery, new energy resources (sun, geothermics). This section will also cover the interdependence between design, construction and energy systems. It will make clear that only the integrated consideration of all components influencing the energy consumption can lead to an optimum solution. Special attention will be given to the economic factors in the energy balance. In the third part, the users of the handbooks will obtain examples of appropriate plannings for one-family houses, flats and office buildings. These examples will also give details on the different costs involved. The fourth part investigates on typical organization and co-operation patterns in the building sector and describes their influence on reasonable plannings for energy sytems. On the basis of an analysis of weak points in the present planning procedures, alternative models will be developed which will enable the best decisions for energy saving problems.

  3. Occupational accidents: a perspective of pakistan construction industry

    International Nuclear Information System (INIS)

    It has been observed that the construction industry is one of the notorious industry having higher rate of facilities and injuries. Resulting in higher financial losses and work hour losses, which are normally faced by this industry due to occupational accidents. Construction industry has the highest occupational accidents rate recorded throughout the world after agriculture industry. The construction work site is often a busy place having an incredibly high account of activities taking place, where everyone is moving in frenzy having particular task assigned. In such an environment, occupational accidents do occur. This paper gives information about different types of occupational accidents and their causes in the construction industry of Pakistan. A survey has been carried out to identify the types of occupational accidents often occur at construction site. The impact of each occupational accident has also been identified. The input from the different stakeholders involved on the work site was analyzed using RIW (Relative Importance Weight) method. The findings of this research show that fall from elevation, electrocution from building power and snake bite are the frequent occupational accidents occur within the work site where as fall from elevation, struck by, snake bite and electrocution from faulty tool are the occupational accident with high impact within the construction industry of Pakistan. The results also shows the final ranking of the accidents based on higher frequency and higher impact. Poor Management, Human Element and Poor Site Condition are found as the root causes leading to such occupational accidents. Hence, this paper identify that what type of occupational accidents occur at the work place in construction industry of pakistan, in order to develop the corrective actions which should be adequate enough to prevent the re-occurrence of such accidents at work site.

    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.

    Full Text Available This paper assesses the potential of historical industrial buildings to be reused as office spaces. Belgrade’s industrial heritage has been classified according to the criteria that influence visual comfort, including glazing area, floor depth, and orientation. Daylight performance of two representative buildings has been analyzed using daylight factor, point in time illuminance and spatial daylight autonomy. Potential improvement strategies that would not have a negative impact on the historical character of buildings have then been discussed. Further studies include increased internal surface reflectance and introduction of roof-lights. The impact of roof-lights on the annual cooling and heating load has been addressed in parallel. Since LEED is the dominant sustainability assessment tool in Serbia, preliminary compliance with LEED v4 Daylight credit has been assessed for all options. The methodology and findings can be applied to a wide range of industrial buildings in similar climatic conditions. [Projekat Ministarstva nauke Republike Srbije, br.

    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.``

  18. Preparing the Building Industry for the New Euratom BSS

    International Nuclear Information System (INIS)

    In the proposed new Euratom Basic Safety Standards (EU-BSS), a reference level of 1 mSv/a is set for indoor external exposure to gamma rays emitted by building materials. An activity concentration index (ACI) is proposed as a conservative screening parameter for identifying building materials that may cause the reference level to be exceeded. An alternative in situ ACI determination method was developed and the validation of this method is discussed. This screening method was used to analyse numerous building materials available on the Belgian market. An attempt was made to identify building materials containing residues from naturally occurring radioactive material processing industries that pass through Belgium, by analysing results from a large scale radiological study of the container traffic in the port of Antwerp. In addition to the regulation provided on the gamma exposure from building materials, specific parts of the proposed new EU-BSS are dealing with radon issues separately. A reference level of 300 Bq/m3 for indoor radon concentration is proposed for the EU-BSS. Relationships between radon exposure and type of building material used, the airtightness of the building and the stage of construction work were determined. (author)

    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.

    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 The construction sectors in the developing countries (DCs have recently demonstratednumerous trends towards globalisation, raising considerable concern in the field.However, the nature of the effect of demand on supply characteristics of the domesticindustry has not been sufficiently discussed with respect to what development measuresare needed in the context of constraints that originate locally to accommodate the globaltrends in DCs. This paper therefore analyses reasons for these trends and attempts toidentify the necessary industry developments to benefit from them locally. For thispurpose, the Sri Lankan construction industry has been taken as a case study and ademand and supply framework is being used to analyse the case. The analysis revealsthat while government policies contribute intrusively in stimulating demand side trends,the role of the contracting firms together with project delivery process and projectprocurement process are also subject to change as a result of these demanddeterminants. In this context, the main focus is concentrated on corporatedevelopments, while wider industry development is also necessary to support them. Asa consequence, both institutional reforms and capacity building are required to enhancefirms’ technological and managerial capacity. The necessity for these developmentmeasures reflects in partly the underdeveloped framework of the construction industry inDCs. Nevertheless, they could still foster indigenous construction capacity within thecontext of global trends.91

    The construction industry has one of the highest frequency levels and rates of work-related injuries, yet the evidence for successful attempts to reduce injuries is generally lacking. The motivational and (safety) behavioural implications of social identification and social categorization among...... construction labourer work crews were investigated to ascertain how their interactions are affected by the social structure and organization of work. Semi-structured group interviews and mini interviews during work were carried out with 13 concrete work crews (totalling 53 persons) at five large construction...... sites. The organization of work fosters social identification within a crew, resulting in distancing from and social categorization of site management. Social identification influences safety behaviour in the crews, where worksite safety rules may meet resistance. Future safety initiatives at large...

    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

    2016-01-01

    Full Text Available Renovation of an existing building is an accomplished stem of the construction industry because it supplies financial diversification for construction stakeholders. Although several construction planning tools and stakeholder alignment exercises have been developed, no tool exists to assist project owners to decide between renovating an existing building and new construction with a comprehensive decision criteria. The objective of this research is to create and test a renovation versus new building support decision tool for construction project stakeholders. The renovation versus new building support decision tool was created based on an extensive review of existing support tools and construction industry needs. The created tool was implemented to evaluate decisions of educational facilities by university officials experienced in project management. Results show the tool was effective in identifying relevant topics for discussion and guiding a group of stakeholders through an exercise in decision-making. Specifically, the tool was implemented by construction management personnel for university facilities currently under construction to evaluate the decision to renovate an existing building or new construction. The main contribution of this research is a framework and support decision tool readily implementable for construction project stakeholders desiring to determine if renovation or new construction is the optimal path for their specific objectives.

    2010-01-01

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

    Full Text Available L’industrie des céramiques traditionnelles, en particulier celle des matériaux de construction, connaît actuellement un important essor au Maroc. Une demande croissante se traduit par la création ou l’expansion de plusieurs unités de production (cimenteries, briqueteries,…. Ces matériaux, produits en fort tonnage, sont susceptibles de confiner certains déchets industriels dans un souci de respect environnemental. Ce confinement ne doit avoir de retombées négatives ni sur la performance du matériau, ni sur la santé. Notre objectif est le recyclage de ces déchets (produits à plusieurs millions de tonnes annuellement qui sont actuellement soit rejetés en mer ou stockés par leur mise en terril. L’objet de ce travail est le recyclage de deux sous produits industriels : le phosphogypse (rejet de la production de l’acide phosphorique et les cendres volantes (résidus de centrales thermiques par leur intégration dans la formulation de produits de la terre cuite. L’avantage est que la microstructure de ces matériaux présente une phase vitreuse susceptible de confiner certains métaux lourds sources de radioactivité. Plusieurs formulations ont ainsi été préparées. Les produits sont caractérisés (DRX, porosimétrie, comportement mécanique,.. en fonction de leur teneur en additifs, de la température de cuisson,… .

    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.

  7. 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

  8. Zero carbon homes: Perceptions from the UK construction industry

    International Nuclear Information System (INIS)

    The take-up of the many voluntary energy efficiency standards which exist in the UK and internationally has been limited. As a result, governments have recognised the need to introduce mandatory schemes through legislation, e.g. from 2016 all new build homes in the UK will be required to achieve zero carbon in regulated energy consumption. However, as 2016 approaches, very few zero carbon homes are being delivered. This paper explores the drivers and barriers for zero carbon homebuilding. The perceptions of the wider construction industry were gathered through a series of semi-structured interviews with professionals involved in commissioning, designing, constructing and regulating housing. The results show that, whilst drivers for zero carbon homebuilding exist, the barriers are currently perceived to be greater than the drivers. The barriers are categorised into five groups: economic, skills and knowledge, industry, legislative and cultural. Mechanisms for policy and industry support for the delivery of zero carbon homes are identified to address these barriers. The research findings highlight the need for a clear and robust policy framework for the forthcoming standard. The Government and industry must prioritise raising public awareness of the need for and benefits of zero carbon homes to help develop market demand. - Highlights: • The strongest drivers were perceived to be in the legislative and economic themes. • More barriers were identified than drivers or potential support mechanisms. • Economic and skills and knowledge barriers were perceived as the most significant. • Uncertainty in zero carbon homes policy is a barrier to zero carbon homebuilding. • Proposed support mechanisms include zero carbon champions and self-build homes

    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.

    Full Text Available Climate change is a global concern. The effect is seen all over the globe and man’s anthropogenic activities is a major contributor. This study evaluates the management of carbon emissions in the Nigerian construction industry by measuring the amount of carbon being emitted from constructional activities within selected organizations. At present, there is no standard of measuring greenhouse gas emissions that is acceptable internationally for all countries so the UK Department for Environment and Rural Affairs (DEFRA methodology of emission monitoring and measurement was used to evaluate the extent of carbon dioxide emissions in these organizations. This methodology was adopted for this study because there was no known national methodology for emission measurement and monitoring within Nigeria. Case studies were undertaken and questionnaires were applied in some construction organizations within Nigeria and the responses from these questionnaires were evaluated and it was found that though there was significant emissions from the Nigerian construction industry, the provision for emissions monitoring and management was lacking, the general awareness regarding carbon emissions and environmental issues across the various organizations evaluated was poor and the construction organizations had no singular person directly in charge of carbon or environmental issues.

    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 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.

    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.

    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.

    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%.

    Directory of Open Access Journals (Sweden)

    Ilsa Kuiper

    2013-12-01

    Full Text Available Building Information Modelling (BIM can be defined as a process of generating and managing information of a building or infrastructure during its life cycle. Whilst the 3D visualisation or dimensional functions of BIM are not necessarily new, it is the usage and integration of this information related to project delivery, management and performance analysis that are challenging current construction industry practices.  Industry has called for the development of more collaborative and integrated contractual arrangements to facilitate the use of BIM. Such recommendations appeal to the ideal use of BIM, but also provide a potential opportunity to seek improvement within the construction industry. This paper proposes a procurement approach to BIM to establish the applicable contractual context to address the potential legal risks and commercial considerations, relative to current practices in Australia. It als ooutlines why BIM, with other enabling technologies, will drive the evolution of contract delivery methodologies.

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

    Directory of Open Access Journals (Sweden)

    Mohd Nawi Mohd Nasrun

    2014-01-01

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

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.

  17. Aspects of Market Differentiation in the Building Industry

    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.

  20. Radon exhalation rates from some building construction materials using SSNTDs

    International Nuclear Information System (INIS)

    Radon appears mainly by diffusion processes from the point of origin following α- decay of 226Ra in underground soil and building materials used. in the construction of floors, walls, and ceilings. In dwellings main source of radon are soil or rock underneath, building materials and portable water supplies. The major release of radon indoors is from building construction materials used. The radon measurements on the ground can give a clue about the hidden uranium. The exposure of population to high concentrations of radon and its daughters for a long period leads to pathological effects like the respiratory functional changes and the occurrence of lung cancer. In the present investigations radon exhalation rates from some soil and other building materials like fly ash, cement and sand collected from Panchkula, Ambala, Yamunanagar, Kurukshetra, Karnal and Panipat districts of Haryana have been estimated. For the measurement of radon concentration in these samples we used α-sensitive LR-115 type II plastic track detectors. The mass and the surface exhalation rates of radon emanated from these samples have also been calculated. The aim of study is the possible health risk assessment due to emission of radiation from building construction materials. (author)

    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.

  12. Research methods of the parameters of residential buildings construction

    Directory of Open Access Journals (Sweden)

    Grigor’ev Vladimir Aleksandrovich

    Full Text Available The analysis of construction theory and practice shows that rational organizational and technological parameters of the construction of residential buildings should be based on the manifestation in time and space of the most important stages construction with their harmonization. Basing on the experience of normalizing the construction duration, it is advisable to express the complex of residential buildings’ construction processes by their basic stages - preparatory period, underground part, aboveground part, external engineering networks and land improvement. The main indicators of the development and implementation of optimization solutions are: the total duration of the construction, the duration of the preparation period, the duration of the construction of the underground part, the duration of the construction of the aboveground part, the duration of external engineering networks laying, the duration of land improvement. The indicators of the total duration of the construction of residential buildings, the construction the underground and aboveground parts are determined on the basis of the operation of one assembly crane on an object of up to four sections. In case of more sections two (three cranes are considered and the total construction duration is set depending on these conditions. The duration of the construction of multisectional buildings is determined basing on the simultaneous construction of the stages or their combination with a certain time shift. However, this approach requires a significant amount of optimization solutions due to its multivariance. Therefore, in order to reduce the volume of calculations in some cases, for example, when planning the development of districts and neighborhoods, statistical methods can be used for determining the duration of the construction basing on the compilation of optimization solutions. The total duration of the construction and the duration of the main stages are multiple

    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)

  3. Building public confidence in the world's nuclear industry

    International Nuclear Information System (INIS)

    Public confidence in the nuclear industry requires two things, which are trust and understanding. Trust is an emotional response based upon an instinctive reaction. Understanding, on the other hand, is an intellectual response based upon facts. To gain public confidence, both of these levels must be communicated and proactive strategies must be implemented to do this. To achieve this objective will require confidence and courage in communication programs. Each company operating in the nuclear sector must be proactive in building its individual reputation and must not retreat from controversy. Similarly, each industry body must continue the Herculean task of building understanding. The nuclear industry has powerful arguments. ICI, BP or Ford did not achieve their licences to operate by keeping their heads down, they achieved their current market positions by building a positive corporate reputation within their respective industrial contexts over many decades. In order to achieve a similar position for the nuclear industry and the companies, their examples must be followed. If it is continued to 'keep the heads down' in the trenches, public opinion will surely bury within it. (G.K.)

    2013-02-01

    Full Text Available Developing cities in India like Nagpur are growing exponentially in population due to industrialization. The ever increasing demand of the natural resources leads to depletion of limited resources and also affects local environment in terms of increasing pollution emissions especially carbon emission. With recourse to composite climatic condition (Nagpur, India the sustainable construction strategy is developed in the present paper. The developed strategy includes conservation of soil, energy, resources, material and water. It provides a systematic approach towards sustainability of building through quantification of energy consumption. Analysis of conventional and non-conventional material and technology on cost, energy consumption and carbon emission parameters helps in highlighting suitable options for sustainable construction. Strategy is validated through a case study of new construction of the residential buildings for enhanced environmental performance. The amount of excavated soil and its reutilization on site is taken into consideration. Locally available sustainable construction materials are compared for material cost, and embodied energy for selection of appropriate construction material. In order to conserve the ground water various options for the low flow devices, roof top rainwater harvesting and gray water recycling and reuse are suggested. Application of sustainable construction strategy to case study building revealed that 97% of natural soil is conserved through backfilling. Estimated carbon emission reduction due to recommended construction materials (sustainable bricks, cement, and steel with respect to conventional options is of the order of 60%. Recommended water conservation options resulted in 57% reduction in ground water demand.  However suggested sustainable construction strategy options estimated in increase in project cost by 13% whose effect can subsequently be reduced over the design life span computations.

    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.

  13. Permeability of some building construction material for radon diffusion

    International Nuclear Information System (INIS)

    In the present work, the radon diffusion coefficient and diffusion lengths for some building construction materials viz: soil, sand, cement, fly ash have been calculated. Radon diffusion and transport through different media is a complex process and is affected by several factors. The diffusion of the radon through the ground is a complex process and is related to the porosity, permeability, which is dependent on grain size distribution, degree of compaction and the water content of the soil. The apparatus designed for the study of radon diffusion through different building construction materials consists of a hollow plastic cylinder of inner diameter 25 cm and length 50 cm deployed vertically. The radon source covered with latex membrane is fixed at the bottom of the cylinder in the cavity. Open-ended cylindrical tubes of diameter 1.5 cm and of length 15 and 25 cm are installed in hollow plastic cylinder. The top end of each diffusion tube holds LR-115 type-II plastic detector such that its sensitive side always faces the source of radon. The building construction materials under study in the pulverized form are filled in diffusion tubes and the system is left undisturbed for a period of 30 days. The detectors are chemically etched in NaOH solution. The alpha tracks are counted using an optical Olympus microscope

    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.

  19. 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.

  1. 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.

  2. Sustainable Construction: Water Use in Residential Buildings in Portugal

    Directory of Open Access Journals (Sweden)

    Miguel Pires Amado

    2013-11-01

    Full Text Available Water is the most important resource to all life on our planet. The impact that buildings have on the consumption of this resource throughout their life cycle (planning, construction, operation and deconstruction but mainly during the operation phase, has resulted in very high and unsustainable consumption patterns. Sustainable development, while a long-term goal, requires that the preservation of natural resources becomes a central point of any project strategy. Water is of vital importance to human life, it should be preserved to ensure its availability for a long period of time. However, little concern has been given to the importance of introducing a selection of more efficient solutions to save water in buildings and consequently increase sustainability in the construction sector. In this context it is on the design phase that the main resource saving water measures should be considered. Research on saving water involves an analysis of quantitative and qualitative measures and their adaptation to different contexts. Nowadays there are systems of voluntary certification of sustainable construction, which can help the design phase to achieve sustainability. This paper discusses a set of measures to reduce water consumption and enable a more efficient use of this resource in residential buildings. The measures presented are focused on user awareness campaigns, systems of rainwater and grey water recycling, the use of more efficient devices and reduction of leaks. The measures are analyzed and compared taking into account the consumption patterns for each device both inside and outside a domestic building and its effective reduction in water consumption

  10. BIM-Based Cost Estimation/ Monitoring For Building Construction

    Directory of Open Access Journals (Sweden)

    Emad Elbeltagi

    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.

  11. Model code for energy conservation in new building construction

    Energy Technology Data Exchange (ETDEWEB)

    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.

    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

    Full Text Available With rapid economic development and industrialization, the construction industry continues to rank among the most hazardous industries in the world. Therefore, construction safety is always a significant concern for both practitioners and researchers. The objective of this study was to create a structural modeling of components that influence the safety performance in construction projects.We followed a two-stage Structural Equation Model based on a questionnaire study (n=230. In the first stage, we applied the Structural Equation Model to the proposed model to test the validity of the observed variables of each latent variable. In the next stage, we modified the proposed model. The LISREL 8.8 software was used to conduct the analysis of the structural model.A good-fit structural model (Goodness of Fit Index=0.92; Root Mean Square Residual=0.04; Root Mean Square Error of Approximation=0.04; Comparative Fit Index=0.98; Normalized Fit Index=0.96 indicated that social and organizational constructs influence safety performance via the general component of the safety climate.The new structural model can be used to provide better understanding of the links between safety performance indicators and contributing components, and make stronger recommendations for effective intervention in construction projects.

  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 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.

  6. An industrial strategy to master the construction of an EPR fleet from Flamanville 3

    International Nuclear Information System (INIS)

    Full text of publication follows. EDF's industrial strategy to master the construction of an EPR fleet from Flamanville 3 (FA3) rests on 3 base ideas. First, an organisation based on Architect engineer approach: As for the construction of the french NPP under operation, EDF approach for the construction of Flamanville 3 is to act as architect engineer that means EDF manages the project of construction in terms of quality, schedule and cost from the detailed design to manufacturing and site activities. EDF is also in interface with the french safety authority for the licensing and in charge to coordinate all the suppliers involved in the project. Secondly, a strong feed back organisation from FA3 experience: the construction of FA3 NPP is in line with the objective given by EDF for a connection to the grid in 2014: the civil phase is now in good progress and several buildings are already achieved. The electro-mechanical erected has started in all the buildings and the first commissioning tests occurred for the electrical distribution. From all these activities, EDF get the lessons learnt and has organised the feedback experience for the future EPR plants to be built. And thirdly, an EPR family organisation involving all EPR utilities partners of EDF: in order to share the experience gained on EPR under construction, EDF has created the EPR Family which gathers all the utilities involved in construction of EPR NPP in partnership with EDF.

    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.

  12. Construction of Residental Buildings on Columns as an Alternative to Construction in Areas Exposed to Floods

    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.

  15. 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.

    2012-11-01

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

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

    Directory of Open Access Journals (Sweden)

    Jill Wells

    2006-06-01

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

  3. PRIVATE AND PUBLIC ENTERPRISE: FLETCHER CONSTRUCTION AND THE BUILDING OF NEW ZEALAND

    Directory of Open Access Journals (Sweden)

    Astrid Baker

    2002-01-01

    Full Text Available This paper shows how a New Zealand company, Fletcher Construction, created wealth in partnership with the state. The first Labour government was elected in 1935 with a firm commitment to full employment and a broad social security system. Because Labour’s determination to get things done through local industry coincided with James Fletcher’s, and then his son’s, drive for company expansion and profits. Fletchers’ design or construction of roads, wharves, saw-mills, flour mills, pulp mills, paper mills, factories, railway stations, university buildings, hospitals, department stores, office blocks, houses, and ownership and management of stone quarries, brickworks and forests, left a mark in almost every town and city in the country. Many projects required building methods and materials new to New Zealand, the innovative use of traditional materials, large-scale plant, specialist, skilled staff and technical know-how from United States and British construction and engineering firms. In this way Fletcher projects drew together many different suppliers, equipment makers, skilled tradesmen and financiers. As a provider of employment in construction and manufacturing, with easy access to established business and political leaders and a powerful influence on policy making, the company became a potent force in New Zealand’s full employment welfare state.

    Mohammadali Noktehdan

    2015-04-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Patrick X.W. Zou

    2006-12-01

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

    2009-11-01

    The fast-growing formation of solid waste, resulting from demographic density, presents itself as one of the most pressing problems to be addressed by governments of large cities all over the world. In Rio de Janeiro, 60% of solid waste stems from the construction industry. Although envisaged by under current municipal legislation, no application of policy regarding systematic recycling of this kind of waste exists in fact. Both sanitation experts and epidemiologists highlight that the deficient sanitary system contributes to the growth of endemic breeding sites, which may reach epidemic proportions. In Brazil, over the recent years, there has been an increase of Dengue Fever cases followed by deaths. In the first half of 2008, the State of Rio de Janeiro was plagued by an intense Dengue epidemic. The city of Rio de Janeiro alone accounted for 48.7% of the cases, in absolute values. By drawing upon an analytical method based on the interrelation between health and sanitation, the outcomes herein indicate that the city of Rio de Janeiro bears a direct relation between Dengue incidence rates and rubble formation from construction - measured by the total area built. Thus, there is a strong urge to implement recycling systems out of construction rubble as a sanitation measure in order to promote Dengue incidence reduction. PMID:19608399

    2013-03-01

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

    Carlos J. Escudero Cascon

    2009-08-01

    Full Text Available Structure pathology detection is an important security task in building construction, which is performed by an operator by looking manually for damages on the materials. This activity could be dangerous if the structure is hidden or difficult to reach. On the other hand, embedded devices and wireless sensor networks (WSN are becoming popular and cheap, enabling the design of an alternative pathology detection system to monitor structures based on these technologies. This article introduces a ZigBee WSN system, intending to be autonomous, easy to use and with low power consumption. Its functional parts are fully discussed with diagrams, as well as the protocol used to collect samples from sensor nodes. Finally, several tests focused on range and power consumption of our prototype are shown, analysing whether the results obtained were as expected or not.

    Full Text Available The complexity that has characterized the market relations, especially in the last two decades, with an ever increasing demand for innovative products and processes, has reflected even more in the traditional activities, such as the building sector. 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.

    Bozsaky, David

    2016-03-01

    Nanotechnology-based materials have previously been used by space research, pharmaceuticals and electronics, but in the last decade several nanotechnology-based thermal insulation materials have appeared in building industry. Nowadays they only feature in a narrow range of practice, but they offer many potential applications. These options are unknown to most architects, who may simply be afraid of these materials owing to the incomplete and often contradictory special literature. Therefore, they are distrustful and prefer to apply the usual and conventional technologies. This article is intended to provide basic information about nanotechnology-based thermal insulation materials for designers. It describes their most important material properties, functional principles, applications, and potential usage options in building construction.

    2012-11-01

    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.

    2008-06-01

    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.

    2012-12-01

    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.

    En este texto, se describen sintéticamente algunas peculiaridades de la edificación residencial de Venecia, analizando su relación con el abanico de problemas estructurales que caracterizan el comportamiento estructural del edificio a lo largo del tiempo. 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 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

  2. 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.

    Over the past decade, benchmarking has increasingly gained foothold in the construction industry. The predominant research, perceptions and uses of benchmarking are valued so strongly and uniformly, that what may seem valuable, is actually abstaining researchers and practitioners from studying...... the perception of benchmarking systems as secondary and derivative and instead studying benchmarking as constitutive of social relations and as irredeemably social phenomena. I have attempted to do so in this paper by treating benchmarking using a calculative practice perspective, and describing how...... organizational relations, behaviors and actions. In closing it is briefly considered how to study the calculative practices of benchmarking....

  7. Round table: The New Constructions; New Build; IAEA Services Nuclear Power Reactor Technologies Construction and Operation

    International Nuclear Information System (INIS)

    The first round-table of Atoms for the Future 2014 focused on the topic of 'The new construction'. Attendees had the opportunity to see Tarik Choho, Chief Commercial Executive Officer at AREVA, Tony Ward, Partner and Head of Power and Utilities at EY, as well as Thomas Koshy, Head of Nuclear Power technology Development Section at the IAEA, share their respective point of view and discuss together. They first started with their own presentation before sitting together at the discussion panel. Tarik Choho explained that there are many opportunities for new builds around the world, and especially in new comer countries. Thomas Koshy brought his expert point of view as an international regulator. He showed that the technology landscape also includes new designs as well as non-electricity generation uses. Those two aspects could bring both opportunities and challenges for licensing. Tony Ward showed how difficult it was to finance such a capitalistically intensive project as a new build, and how one could try to find an electricity retail price which is acceptable for both the general private consumer and the plant operator. All speakers agreed that preparation was core to a nuclear new build project. They also pointed out that every project involves more and more actors, and that it could be challenging to let everyone have the appropriate say

    Major changes in the regulation of electric and natural gas industries during recent years have forced energy companies to explore opportunities in small-size Combined Heat and Power systems. These differ fundamentally from the traditional model of central generation and delivery since small, modular electric generators can be located very close to end-users inside a building or a single house within an industrial area, combined with the production of heat and cold. In particular, interest is growing in the new technologies for sub-100kWe units, including systems based on thermophotovoltaic (TPV) technology. TPV generator tubes can be inserted into hot furnaces to generate electricity and low-grade heat. In this generator tube, a water-cooled GaSb photovoltaic converter array inside the tube faces outward toward an infrared emitter liner mounted on the inside surface of the closed-end tube. Each tube can be sized to generate several kW and a given furnace can heat several tubes. We have conducted pilot experiments on key components in order to develop the concept just described. This includes a pilot scale array tested in an electrical furnace that heat a 3″ diameter alumina tube with an infrared emitting liner. Also, a silicon carbide tube with a water-cooling system was tested in a ceramic fiber lined furnace equipped with a commercial 200 kW flameless regenerative burner, simulating a TPV generator tube in such a system.

  9. Energy choice criteria and approaches in the building industry

    International Nuclear Information System (INIS)

    With the recent evolutions in the global and local energy context, any actor of the building sector must contribute to reduce the environmental impact of new or existing buildings by integrating environmental and energy optimization elements during their construction or rehabilitation. This article presents, first, the global energy problem that nations, groups of nations and economic agents have to cope with (demographic growth, environmental impacts, market tensions and resources depletion, markets liberalization, sustainable development and sustainable decay). The second chapter presents the main elements of the evolution of the economic, legal and environmental context and their impact on energy markets (environmental constraints, security of energy supplies, opening of energy markets, European directives under preparation, decentralized energy production technologies). The last chapter describes the energy choice criteria according to the new environmental constraints (general problem, prices, environmental impacts, decision making). An overview of energy resources and markets, of electricity prices formation, and of the international dispositions against greenhouse effect are gathered in appendixes. (J.S.)

    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.

    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.

    Scheib, J.; Pless, S.; Torcellini, P.

    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.

    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.

    Full Text Available The construction sector has, in Spain, a remarkable importance, due to the contribution to GDP, around 10%, and employment (10% and the wide business network it includes. The present economic situation and the residential market saturation have led to a sharp contraction in building activity, after a long period of growth.This is, therefore, a good time to perform a structural analysis to identify the determinants of profitability and assess the projection of the companies operating therein.This paper identifies the rules of competition and reasonable business expectations for coming years, using the Model of Five Competitive Forces. This analysis will show opportunities and difficulties for constructors as a tool in making decisions. The success of the strategy will depend on the management of strengths and capabilities, especially in times of change in the competitive environment.

    2007-01-01

    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.

    2011-12-01

    Full Text Available There has been an intense debate in the media and among academics on how the great financial crisis has affected the global economy, and how the effects have differed in different regions of the world. This survey was designed to establish to what extent the building industry has been affected by the GFC and the Euro crisis. Over the last months we have asked senior academics and executives in construction businesses what has happened up to now in their region, what will most likely happen in the near future and in the long term. The answer is that in developed economies the effect has been a substantial downturn as finances have dried up while in developing economies in most regions, demand has been sustained due to population growth with ever increasing needs for residential building and infrastructure. While there is some apprehension about the potential effects of the Euro crisis deepening, no-one seems really worried. In the long term there is an agreement, in developed and developing countries alike, that current business models do not work and that the industry has to reinvent itself to be sustainable.

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.

    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.

    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.

  18. 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.

    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.

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

    International Nuclear Information System (INIS)

    The study aimed at working out a catalogue of criteria for the effective work of a liaison center for the machine building industry within the planned system of information and documentation of the German Government. By selecting this objective, the investigation methodically demanded a continuous change between theoretical analysis (study of literature, analytical deduction of the framework for a user-oriented information system) and empirical observation of information behaviour in the machine building industry (personal interviews with enterprises and important information sources for the machine building industries). An information system keyed to the information needs of the machine building industry must cover three main phases: Collection and documentation of information, selecting and procuring the needed information as well as encouraging and consulting the clients on the use of information. These different tasks complement one another, they correspond to different functions within enterprises: management, staff, and information function. Central point of a liaison center must be the task of selecting the required information (making information available, selling good information, analysing the information needs of clients), completed by fields of activity in documenting information (specifically for the machine building industry) and consulting clients on the use of information (agency for contacts, drawing the clients' attention to the complexity of machine building problems). A concrete catalogue of criteria for an effective conception of a liaison center for the machine building industry has been worked out. (orig.)

    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.

  20. Guide for a building energy label. Promoting bio-climatic and solar construction and renovation

    Technically speaking, building experts have the knowledge to deal with thermal inertia of buildings, solar gains, insulation, efficient ventilation, and daylighting... to get low energy buildings that provide comfort for the users. Buildings should always be designed according to the specificities of the local climate, according to a ''solar and bio-climatic construction'' approach. It is not always possible to fully apply these principles, particularly in urban areas with high density. However, this is unacceptable to keep building with such errors as insufficient insulation and direct electrical heating, single glazing, thermal bridges, low efficiency heating systems. This guide aims at encouraging the building experts to take into account the energy efficiency. Implementing a building energy label will allow general public to be aware of this issue and then, and will then lead to develop better practices. (author)

    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.

    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.

    2016-04-01

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

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

    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.

    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.

  6. Ecological and Economic Use of Energy by Optimization of Building Construction

    International Nuclear Information System (INIS)

    A major part of energy used in daily life is consumed by heating buildings during cold weather periods and for cooling buildings at warmer times. Another major use of energy takes place during production of building materials, construction of the building itself and the depletion and disposal of this building at the end of its lifecycle. Therefore it seems apparent, that effective conservation and saving of energy is a very comprehensive and total approach. The topic is not solely energy saving, it rather is the most effective use of economical and ecological resources. To be energy conscious we have to give closer look to all phases in the existence of a building, and not only of the building. The human being as well must be thoroughly considered in his surrounding, all aspects of his housing suspected for the waste and potential of energy use. So human itself, with his well being in the house, is a major source of energy use. Even the humans health and sickness with its need for cure will cause significant energy input. In the first phase of energy saving programs two aspects should be focused: 1. Primary energy need of construction materials: Primary energy need is the amount of energy used to produce a construction material; from its base origin up to assembling in the housing. Complete ecological balances already exist for a number of materials. Significant difference between materials is observed. The potential for energy saving is impressive. At least 10-30% total energy conservation during the lifecycle of a building appears likely. In many cases a strong positive impact on local economy is expected too. 2. Energy saving by improvement of the thermal quality of buildings: Energy conscious construction of buildings shows an enormous potential for saving. Thermal insulation and effective heating and ventilation systems promise energy savings in the amount of 30-70%. Infrared thermal building analysis and software simulations used prior revitalization of

    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.

    2016-03-01

    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 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.

    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.

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

    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.

    The Ground-penetrating radar (GPR) analysis of some modernist buildings of the Technical Industrial School of Barcelona allow us to obtain valuable information of the underground constructions, corresponding to ancient structures of the preceding factory. The actual school is building on the modernist industrial complex. Many changes in the structure were carried out to adapt the structure to its actual use. The obtained GPR data was compared with the information, documents and photographies from the historical archives of the Diputación of Barcelona (Spain). To obtain accurate results and right interpretations, velocity analysis is performed in the different studied areas. The velocity values are used to convert accurately the two-way travel time into depth. The aim of those velocity estimations is obtain the minimum error in the final interpretations of the profiles. The velocity analysis is carried out using two different methods: calculating velocity using the reflection in anomalous bodies into the medium at a known depth, and calculating velocity from the hyperbolic events of the radargrams, caused by finite anomalies of the medium. The present tubes and conductions which are in use nowadays, have known depths. Then, velocity is obtained from the two-way travel time obtained for the reflected wave in that anomalous body. This method allow us to known velocities in areas where those elements are presented, which are mainly in the ground under the streets of the school. The reflection produced in unknown bodies which have finite dimensions, is obtained as an hyperbolic event. The averaged velocity of the medium over these bodies is calculated from the equation of the hyperbola. This method was used mainly where known elements were not presents in the ground. These areas are mainly the buildings of the school. Experimental velocities are understand as the averaged velocity of ray-path. The obtained values are applied to each area, to calculate depths of the

    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.

    The construction industry is a major generator of waste material. Construction waste should be minimized at source and if we are to significantly reduce the level of construction waste designers should consider reducing construction waste during the design process. The majority of construction waste is generated from the concreting process. In general, any reduction in on-site concreting leads to waste reduction. Precasting and prefabrication therefore offers significant opportunities for the reduction of waste. If precasting is adopted there are significant implications for the design phase of the project. Additional information is needed by design staff and construction expertise is required as part of the design process. This paper shows how information modelling and Design Structure Matrix (DSM) techniques enable designers to model and understand the implications of such decisions within the detailed design process.

    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

    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.

    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.

  11. A supermolecular building approach for the design and construction of metal–organic frameworks

    KAUST Repository

    Guillerm, Vincent

    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.

  12. 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.

    The thermal activation of concrete ceilings, also concrete called core activation, is getting a large spread in the last years. Since the water tubing registers must be brought in during the concreting process, this technology is not applicable in the case of reconstructions. To be able to use the energetic advantages - which occur with the use of water temperatures near room temperature, also within the construction area, there is a set of suggestions. A version, which includes even the storage in the available concrete ceilings, is examined in consideration of is efficiency. (orig.) [German] Die thermische Bauteilaktivierung von Massivdecken - auch Betonkernaktivierung genannt - hat in den letzten Jahren eine grosse Verbreitung erfahren. Da die wasserdurchflossenen Rohrregister waehrend des Betoniervorgangs eingebracht werden muessen, ist diese Technologie im Sanierungsfall nicht anwendbar. Um die energetischen Vorteile - die beim Einsatz von raumnahen Wassertemperaturen auftreten - auch im Sanierungsbereich nutzbar zu machen, gibt es eine Reihe von Vorschlaegen. Eine Variante, die sogar die Speicherung von vorhandenen Massivdecken einbezieht, wird auf ihre Leistungsfaehigkeit untersucht. (orig.)

  17. Rationalization of design and construction of buildings for nuclear power plants

    International Nuclear Information System (INIS)

    This article presents various rationalization methods introduced in the past few years for design and construction of BWR nuclear power plant buildings. When the site for a nuclear power plant has been decided, investigation is made on various aspects of possible earthquakes, based on which anti-earthquake design for the plant site is established. The next step is to examine the displacements and stresses that may occur to various parts of the bulding from a postulated earthquake. This is normally called the earthquake response analysis and consists of calculating the behaviors of the buildings using large computers. A seismic controlled structure system has recently proposed, aiming to reduce the displacements and stresses of the building itself by controlling the flexibility of the installed seismic apparatus against the input of external loads. Lately, high strength concrete and high strength reinforcing steel bars (rebars) are being considered for practical application. If advanced computers and related accessories are utilized to the maximum, it will lead not only to efficiency in the design work but to the possibility of optimized design. For rational construction, a combined scaffolding and temporary support has been devised to reduce the time and volume of required temporary work. What have been developed for rationalization of construction work also include robots for heavy weight rebar fabrication, horizontal reed blind type rebars, portable concrete distributor, all weather environment facilities, and construction materials conveyance system.

    2015-10-15

    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.

    2015-06-01

    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

    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.

    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.

    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.

    Full Text Available Any interaction involving individuals, whose objectives are conflicting with each other, may establish a negotiation process. In a negotiation, each party should develop his/her own strategy and, normally, a win-lose vision is frequently adopted. The main consequence of this behavior is a result, in which both parties lose, especially when the negotiation involves more than one aspect, such as negotiations resulting from purchases of material for construction industry, where aspects like price, quality and lead-time should be considered. Most of the negotiation involving construction industry adopts a win-lose vision; and, commonly, only the issue price is considered. The goal of this paper is to propose a framework to support negotiations between two parties (buyer and seller in the supply chain of construction industry. The combination of a win-win strategy with a multicriteria analysis produces a best compromise solution for both parties. A simulation of negotiation using realistic data is presented.

    2010-12-01

    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.

  5. Construction Safety And Health Factors At The Industry Level: The Case Of Singapore

    Directory of Open Access Journals (Sweden)

    Charles Y.J. Cheah

    2007-12-01

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

  6. The implementation of clean development mechanism (CDM) in the construction and built environment industry

    International Nuclear Information System (INIS)

    Greenhouse gas emissions due to human activities are the main contributors to global climate change, a problem that should not be ignored. Through the clean development mechanism (CDM) introduced under the Kyoto Protocol, developing countries are able to earn certified emission reduction (CER) credits through a myriad of emission reduction projects. This study aims to explore the potential of implementing CDM projects in the construction and built environment (C and BE) industry, which has been criticized for not only consuming an enormous amount of resources, but also for contributing to adverse environmental health. In this research, we limit the boundary of the C and BE industry to include the planning, procurement, construction, occupation and refurbishment/demolition phases of a project's life cycle. Surveys and in-depth follow-up interviews with experts have generated useful insights pertaining to CDM potential and its adaptation into the C and BE industry. From this foundation, this paper evaluates the current obstacles to CDM and presents feasible suggestions to increase CDM projects related to the C and BE industry. - Highlights: • We review the development and limitation of CDM relates to the construction and built environment (C and BE) industry. • We obtain experts' opinions on the feasibility of CDM in the C and BE industry. • Validation, monitoring, verification and additionality of CDM projects are crucial. • Experts agreed that most of our suggestions are feasible in principle

  12. Potential exposure to natural radiation inside dwellings, due to phosphogypsum use in the building industry

    International Nuclear Information System (INIS)

    The interest of building industry to improve the standardization of building processes result in a increasing tendency of using the gypsum as boards, and as a projected gypsum mortars. On the other hand, the need of reuse industrial wastes to avoid environmental impact resulting of their deposition and to reduce the management costs, indicates the building industry as an important user of large quantities of industrial wastes, mainly that generated in the ore milling The industry of phosphate fertilizers is a typical example of this interaction. The phosphate rock milling through the wet process, reacting phosphate rock with sulfuric acid, produces substantial quantities of calcium sulfate as a by-product known as phosphogypsum, that are stored in stockpiles. The phosphate rock contains radionuclides of the U and Th decay series. During the chemical attack these radionuclides are distributed in different proportions between the phosphoric acid and the phosphogypsum. This work presents the radiological characterization phosphogypsum, produced by two national fertilizers industries. A methodology to quantify the radiation exposure, in a reference dwelling , due the use of phosphogypsum considering different scenarios, was established. The external irradiation and the inhalation of radon and thoron and their decay products in indoor air were considered. The values of individual effective dose equivalent ranged from 0.12 to 1.95 mSv.a1, depending on the phosphogypsum origin and the scenario considered. About 80% of the dose rises from the inhalation of thoron and its decay products. The results show the importance of Th series radioactive disequilibrium in the assessment. Depending on the phosphogypsum origin and scenario of use, the dose values justify the control of this practice. The general conclusion is that this practice have to be considered case by case and the proposed methodology is suitable to assess the dose and the radioactive disequilibrium consequences

    2015-01-01

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

  16. THE EVOLUTION OF THE DESIGN AND CONSTRUCTION OF MASONRY BUILDINGS IN AUSTRALIA

    Directory of Open Access Journals (Sweden)

    Adrian Page

    2012-12-01

    Full Text Available Masonry is a construction material which is widely used in Australia in a number of forms (fired clay, concrete, calcium silicate, natural stone, autoclaved aerated concrete and in a wide range of both loadbearing and non-loadbearing applications. As such, it serves as the primary structural element in structures such as 3-4 story “walk up” apartment buildings or low rise commercial structures, or as a veneer or infill in housing or high rise framed construction. Despite its current widespread use, for masonry to remain a viable construction material in the future, design and construction practices need to be flexible, able to adapt to change and be receptive to innovation. This applies not only to advances in materials technology and the development of new products and building systems, but also an effective response to changes in the regulatory framework which have an increasing emphasis on thermal and acoustic performance, seismic resistance and sustainable practices. In this context, an overview of the Australian past, present and possible future masonry scene is given.

    Time-dependent structure analysis theory has been proved to be more accurate and reliable com-pared to commonly used methods during construction. However, so far applications are limited to partial pe-riod and part of the structure because of immeasurable artificial intervention. Based on the building informa-tion model (BIM) and four-dimensional (4D) technology, this paper proposes an improves structure analysis method, which can generate structural geometry, resistance model, and loading conditions automatically by a close interlink of the schedule information, architectural model, and material properties. 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 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 Background: In brick kiln and construction industry the exposure to carbon monoxide and silica dust is the most common occupational hazard to the workers in these industries. A study on occupational health hazards of working women in these two unorganized sectors was undertaken by Lokmanya Medical Research Centre. Objectives: To study the effect of work site environment on the health of the women working in brick kiln and construction industry. An attempt was also made to study the seasonal changes in the concentration of carbon monoxide and dust at the worksite. Material and Methods: A cross-sectional study was conducted among the working women (age 18-40 years at brick kilns and construction sites during summer and winter season. They were examined primarily to assess the effect of working environment on health. Gasteck Detector Pump of model 800 and air sampling instrument (SKC Air Check–52 were used to measure concentration of carbon monoxide and dust in the air respectively. Results: There were 66% of women who were in the age group of 18-40 years and most of them (94% were married. At brick kiln sites, average CO exposure was 62.8 ppm and 55.5 ppm and average dust exposure was 3 3 146.1 mg/m and 91.4 mg/m in summer and winter season respectively.At construction sites, average dust exposure was 41.5 ppm and 90.8 ppm in summer and winter. Conclusion: Both exposure to CO and dust were more in summer than in winter in brick kiln industry whereas in construction industry the exposure to dust was more in winter season. A high level of morbidity in the form of headache, bodyache, problems with vision, cough and breathlessness were observed in both industries. It is strongly recommended to take pollution control measures.
