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.

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

Full Text Available Malaysian Construction Industry has been urged to use innovative construction technique and to shift from traditional practice of brick and mortar to Industrialized Building System (IBS construction. IBS is defined as a construction technique in which components are manufactured in a controlled environment (on or off site, transported, positioned and assembled into a structure with minimal additional site works. On the other hand, the issues of sustainability and green construction have been duly highlighted in the Construction Industry Master Plan (2005 – 2015 as being of significant importance for the Malaysian construction industry. The Malaysian government is also committed to addressing sustainability issues and meeting its target and obligations in this regard. This paper highlights several aspects of IBS that has the potential of contributing to green construction and sustainability. IBS promotes sustainability from controlled production environment, minimization of waste generation, extensive usage of energy efficient building material, effective logistics and long term economic stability which can contribute to better investment in environment technologies.

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

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

Full Text Available The physical reasons for building structures destruction are both the forces arising at stress-strain state of construction elements and external influences arising at emergency situations, as well as their moments, impulses and periodic impulses with the frequencies close to of fluctuations frequencies of construction elements. 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.
Highlights: → Vacuum Insulation Panels (VIP), a high thermal resistance building insulation. → Review of research into VIPs for building applications. → High cost and uncertainty of service life are two barriers for VIP use in buildings. → SiO2/SiNx coated PET laminate- candidate for high barrier VIP envelope. → The optimum combination of VIP core and envelope yet to be determined. -- Abstract: Demand for energy efficient buildings has increased drastically in recent years and this trend will continue in the future. Insulating building elements will play a key role in meeting this demand by reducing heat losses through the building fabric. Due to their higher thermal resistance, Vacuum Insulation Panels (VIPs) would be a more energy efficient alternative to conventional building insulation materials. Thus, efforts to develop VIPs with characteristics suitable for applications to new and existing buildings are underway. This paper provides a review of important contemporary developments towards producing VIPs using various materials such as glass fibre, foams, perlite and fibre/powder composites. The limitations of the materials currently used to fabricate VIPs have not been emphasised in detail in previous review papers published. Selection criteria, methods to measure important properties of VIPs and analytical and numerical models presented in the past have been detailed. Limitations of currently employed design tools along with potential future materials such as Nano/microcellular foams and SiOx/SiNx coatings for use in VIPs are also described.

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

Full Text Available 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.
Full Text Available Conventions theory was developed in part to explain how heterogeneous actors with asymmetrical information manage to carry out economic transactions. In particular, how do these actors work together to reduce uncertainty about the quality of the commodities involved? While most applications of conventions theory have been in the agro-food industry, this paper looks at the newly developing green building industry as an example of economic production that relies on multiple constructions of quality in its production and consumption processes. Previous work has shown that conflicts over quality often arise when the parties involved are operating under different conventions, a danger with the multiple actors that must cooperate to produce (and consume a green building. Furthermore, in the case of green buildings, uncertainty about a product's performance does not end at the point of transaction; the quality of many of the materials or processes involved can only be proven over time. I argue that the producers of green buildings and green building materials have overcome the problems of a uncertainty over time and b conflicts over the meaning of quality by drawing on all four conventions simultaneously. Furthermore, this simultaneous incorporation of trust, third-party standards, price, and the common good, as enacted through the Leadership in Energy and Environmental Design (LEED standards of the U.S. Green Building Council (USGBC, is one of the main reasons for the phenomenal growth of the green building industry among public, private, and non-profit clients.
We have constructed simultaneously four buildings, AB building, DB building, DC building, and KA building in the spent nuclear fuel reprocessing plant at Rokkasho village in Aomori. We were able to complete the massive and complicated building in the highest quality by the method of prefabrication of site work in a short construction term. Moreover, also in the severe winter season, we practiced construction work intentionally. Consequently, we completed three buildings, AB building, DB building, and DC building without the trouble last year. (author)
Full Text Available The Cole Royal Commission enquiry into the building and construction (abbreviated to ‘construction’ sector recommended controversial workplace-relation reforms for that sector. The recommended changes are likely to be enshrined in legislation within the year. The Commission drew on analyses of industrial disputes that focused, in the main, on quite recent experience. This paper attempts to give a broader historical perspective on disputes in that sector by considering the pattern of disputes for the entire post-World War II period. Accordingly, data on disputes and employees during the entire period are gathered from Australian Bureau of Statistics current and archived sources. These data are classified according to sector (construction versus non-construction and analysed. It is found that the strike rate has, on average, been greater in the construction sector than in the non-construction sector. However, there have been periods during which disputes in the construction sector have been relatively low. The most recent period was during the period of the Accord (1983-96, during which the strike rate in the construction sector fell relatively strongly. The analysis of this relatively broad historical period draws attention, among other things, to the possibility that the sort of strategies employed during the Accord years – strategies of cooperation and consensus building – may provide a more effective means of bringing industrial peace to the workplace relations scene of the construction sector than policies that are relatively confrontational.

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.

Reverse logistics in construction refers to the movement of products and materials from salvaged buildings to a new construction site. While there is a plethora of studies looking at various aspects of the reverse logistics chain, there is no systematic review of literature on this important subject as applied to the construction industry. Therefore, the objective of this study is to integrate the fragmented body of knowledge on reverse logistics in construction, with the aim of promoting the concept among industry stakeholders and the wider construction community. Through a qualitative meta-analysis, the study synthesises the findings of previous studies and presents some actions needed by industry stakeholders to promote this concept within the real-life context. First, the trend of research and terminology related with reverse logistics is introduced. Second, it unearths the main advantages and barriers of reverse logistics in construction while providing some suggestions to harness the advantages and mitigate these barriers. Finally, it provides a future research direction based on the review. PMID:26018543
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

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

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

The South African building industry today is presented with a unique challenge to provide alternative low-cost housing at a rate that conventional construction methods and materials cannot meet. It is generally acknowledged that the locally produced polymers such as polyethylene and polyvinylchloride can alleviate some of the problems encountered with conventional construction techniques. The radiation-modification of these polymers plays an ever increasing role in modifying the physical properties and extending the applications of these materials. Whereas in the past the technical and economic aspects inherent in this technology restricted the more general use of radiation crosslinking, large-scale irradiation facilities are now available on a service basis for the radiation-modification of polymers and can thus overcome these earlier limitations - especially so in the case of the smaller convertor. In agreement with the crosslinking of thermoplastics in general, radiation crosslinking can lead to important changes in the polymer properties such as, an improvement in the thermal stability thereof and the suppression of its flammability, an improvement in its dimensional stability and many other mechanical properties including abrasion resistance. This process also improves the resistance to common solvents for these polymers. Recent developments in South Africa to enhance the properties of common thermoplastics for the building industry through radiation processing is discussed

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 Governments 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

This paper investigates the amount of energy required to construct buildings, and the resulting carbon dioxide emissions to the atmosphere from the fossil fuel components of that energy. Energy requirements and carbon dioxide emissions are compared for typical commercial, industrial and residential buildings, using New Zealand as an example. A modest change from concrete and steel to more wood construction could lead to a substantial reduction in energy requirements and carbon dioxide emissions, but the sustainability of such a change has significant forestry implications.

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

Full Text Available The 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.

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.

Indonesia is one country that is highly prone to earthquakes because it is located at the juncture of four tectonic plates, namely the Asian continental shelf, the continental shelf of Australia, the Indian Ocean plate and the Pacific plate. In the southern and eastern parts of Indonesia there is a volcanic belt that extends from the island of Sumatra, Java and Nusa south eastern Sulawesi, the sides in the form of old volcanic mountains and the lowlands are mostly dominated by swamps. The condition of potential and proneness to disasters such as volcanic eruptions, earthquakes, tsunamis, floods, and landslides. Indonesian society have a local knowledge for facing disasters. Local communities in particular areas have local knowledge for facing disasters. Such knowledge is commonly kept by members of the communities and applied to their environments, including houses. This research aims to describe disaster-friendly Sundanese traditional building construction. It employs the evaluation method, by comparing Sundanese traditional house construction to the standards of disaster-friendly construction. The results indicate that the Sundanese traditional building constructions have been qualified as disaster-friendly buildings.

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

Full Text Available 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.

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.``

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 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

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.

Total construction period could be shorten by prefabricating structures efficiently in another yard and reducing working hours on site, which would reduce work at height or congestion work and also upgrade safety at work. Construction period shortening would surely reduce expenses during work and advance operation start of electric utilities. Construction of reactor building, turbine building, water intake and drainage canal was performed on a relatively large scale and a big share of whole schedule. This article summarized basic technologies to shorten construction period for reactor building/turbine building and water intake and drainage canal. Advanced methods of reactor building/turbine building; (1) modularization of equipment and skeleton, (2) utilization of concrete mold, reinforcing bar and steel frame, (3) precedent steel frame method and (4) steel plate reinforced concrete (SC) method, were outlined and their application examples were shown to reduce work on site and improve work efficiency. As for water intake and drainage canal construction, (1) precast concrete method, (2) SC method and (3) steel plate shell method were described with application examples. Construction procedures and problems using mega block method for water intake and drainage canal were also introduced. (T. Tanaka)

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.

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 ânewâ 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 âmarketing mixâ: 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 âfeesâ policy rather than both product innovation and promotion is also interesting. Big percentage of the responding contractors assumes these âfeesâ 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 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 industrys dependency on foreign workers. In addition, this study confirms that a huge amount of material wastage can be reduced by the adoption of prefabrication. This study also revealed that the rates of reused and recycled waste materials are relatively higher in projects that adopt prefabrication. Conclusion: Thus, the adoption of prefabrication and IBS has potential in the reduction of huge waste generation and management problems in the construction sector of Malaysia although there are some challenges in the adoption of prefabrication.

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

Full Text Available 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.

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%.

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.

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)

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

The complex, dynamic, and continually changing nature of construction work has been recognized as an important contributor to the high rates of injuries and fatalities in the industry. Cranes are a central component of many construction operations and are associated with a large fraction of construction deaths; in fact, estimates suggest that cranes are involved in up to one-third of all construction and maintenance fatalities. Safety and health professionals serving the construction industry need adequate training and knowledge regarding available crane safety devices and procedures so that they may insure these techniques are effectively utilized during construction operations. This paper reviews available information on crane-related injuries, currently available safety devices, and commonly used crane safety procedures. Recommendations for improved crane injury prevention and future crane safety research are given. PMID:11783872

The reasons behind the internal fraud and corruption problem as well as the types of prevention methods were investigated; and as a result various recommendations were made. To this end, a risk awareness questionnaire was used to understand the behavioral patterns of the construction industry, and to clarify possible proactive and reactive measures against internal fraud and corruption. The type of fraud experienced by Turkish construction companies was also surveyed in the questionnaire. The questionnaire was sent to 89 firms; and depending on the collected data, certain recommendations for construction industry professionals were provided. PMID:22371033
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.

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

Full Text Available 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. The

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

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.

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.)

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
Full text: One of possible method of realization of the terrorist acts is using gases and liquids, which easily permeate through the constructive materials of walls, floor, ceiling, roof, etc. into buildings by the capillary action of the pores. Toxic volatile organic compounds, organic and inorganic gases, radioactive elements, especially, which emits alpha particles can be used as the dangerous substances. Increased ventilation may help in removing the gases, but can actually increase the gases level by increasing the suction through the pores of concrete. If the gases and liquids are soluble in water and are easily volatilized from it, they can also get by groundwater up to underground structures and penetrate inside through opening and pores in concrete or pushed by hydrostatic pressure. The purpose of this work is creating a method to reduce concentration of toxic and radioactive gases in homes, buildings, underground buildings, tunnels, hangars, garages, bomb shelters, etc. The most effective method to prevent penetration of radionuclides into premises of buildings and underground structures through walls, roofs, floors is using special chemicals, which seal micropores inside the construction materials against gases. Worked out chemicals which consist of blend of polymeric compounds are described in the paper. Radioactive gases permeability in constructive materials after treatment by chemicals was studied. Influence of types of cement, sand and gypsum, preliminary treatment by different chemicals, different types of polymeric compounds, time between treatments, moisture of materials, time between preparation of chemicals and treatment of materials (aging of chemicals), time between treatment of concrete and testing (aging of treated concrete) were examined. Experiments have shown that our method allows reducing the coefficient of gas permeability 200 - 400 times

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.

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.

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 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.
Full Text Available There are two mainstreams in the building industry in the area of carbon fibers: rehabilitation and use as building material. The using of carbon fiber as a building material is taking place slower than as rehab system due to the very low cost of traditional building materials, the limitations of composite structure manufacturing processes and the conservative building regulations concerning materials in all the industrialized countries. However, these three issues are being solved in a very efficient way, as we will see along the coming paragraphs of this paper.
This paper is split in two parts, first the carbon fiber as a material system, its typologies, manufacturing processes and industrial presentations will be described. Second, rehab and building applications will be analyzed.
En el área de fibra de carbono en la construcción hay actualmente dos líneas de trabajo: reparaciones e implantación en obra: La implantación en la obra civil está avanzando más despacio que la utilización en reparaciones debido al bajo coste de los materiales tradicionales, a la limitación de procesos de fabricación de estructuras de materiales compuestos y al conservadurismo de las normativas de edificación y obra civil en todos los países industrializados. Sin embargo, los tres asuntos mencionados están siendo abordados con eficiencia, como se explicará más adelante. En el presente artículo, se va a describir, el primer lugar, la fibra de carbono, sus tipos, procesos de fabricación y presentaciones industriales. En segundo lugar se tratarán las aplicaciones en la construcción, haciendo énfasis en las reparaciones y en la implantación en obra civil.

The results are applied by the Public Transport Authority in a new budgeting model, while the agency investigates the...... then applied on the Public Transport Authorities' main account structure of units and costs, and a method for assessing the possibilities of achieving effects of repetition for each account is described. Finally, the report summarises the core conditions necessary to take into consideration in relation...
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.

Examples are given of the structural use of aluminium in the Civil Engineering and Building Industries. These are taken from various periods within the past 50 years. The contrast between relatively widespread use for quite major structures in the 50' and 60's with the niche markets of today is striking. Paradoxically, availability of technical guidance, linked to professionally prepared educational material, has never been better. (orig.)

We evaluate the technical feasibility of applying emerging wireless network technologies for re-sources tracking at building construction sites.We first identify practical constraints in solving resource-tracking problems in an enclosed or partially covered environment.We then compare pros and cons of available localization principles and examine the latest wireless communication technologies,including Wi-Fi,Bluetooth,Ultra-Wideband(UWB)and ZigBee.We find that the ZigBee-based wireless sensor network and the received signal strength indicator(RSSI)localization method are most promising to tackle on-site tracking of construction resources.Finally,we anticipate some application challenges associated with deploying wireless sensor networks for resources tracking in the practical context.
Outsourcing is an organizational measure that changesthe ressource dependencies of a Company. In this paper, a framework is developed from the perspective of the ressource dependence approach to explain strategic outsourcing in the German engine building industry. On the basis of the NIFA panel......, which describes the Development of this industry, the framework is examined in cross-sectional studies. It can be shown that the RDA contributes to an explanation of organizational changes, both outsourcing and insourcing. In addition, the longitudinal studies show the significance of the strategic...
Full Text Available The construction industry operates primarily as a system of sub-contracting and purpose built alliances. There is a wide spread of stakeholders involved in conceiving a building project through typical stages such as design, finance, build, manage, upgrade and, ultimately, replacement and a corresponding need for communication and cooperation. Specialists who can prevent bridges falling down or who build 20 storey buildings are seen as the hard-nosed, action people who have helped bring us into the modern era. However, there are intuitive activities and disciplines which help us to achieve the type of construction achievements that have been the hallmarks of the 19th, 20th and now the 21st centuries. Most of these so called soft disciplines are about how one helps people, often highly skilled, achieve those construction and engineering goals. The key components are consultation and communication. Communication strategies should be based on a thorough understanding of the ways that humans co-operate in joint undertakings, the key principles of social dynamics and learning theory plus the ways in which people deliver, accept and understand words and pictures. The disciplines of organisational and environmental psychology have become a basic fundamental of modern business activities from management and organisational strategy to marketing and customer relations and to the improvement of working, recreational and living environments. However it is rare for a mature industry such as construction to adopt or examine those disciplines for guidance about either strategies or operations. This is despite the fact that the construction industry is almost entirely based on the principle of sub-contracting, business and professional alliances, all of which require understanding of environmental psychology and social dynamics in order to build trust, reputation, teamwork and client satisfaction. There is therefore a major need for communications to be

The 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...
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.
