Material selection in sustainable projects affects the environment a great deal. Selected materials gain importance as they can contaminate the environment and can produce waste during construction. Use of limited resources has also environmental impacts. Thus, considering sustainable materials in the projects and appropriate consumption of available resources are important for sustainability considerations. The danger of running out of resources and the consequences of contamination of the habitat point out to the importance of green building certification systems. Issues such as storage and collection of recyclables, waste management planning, PBT source reduction, sourcing of raw materials, material ingredients, and design for flexibility that are treated in this category are difficult to implement in developing countries, mainly because they are based on local practices. The use of materials and resources accounts approximately for 11% of the points a building can receive for LEED v4 certification. However, the use of LEED in countries other than the U.S. can be controversial as local conditions are effective in earning credentials required for certification. This study aims to review the “materials and resources” category of LEED. Comparison of local practices in selected developing countries is made based on credits in this category to provide guidelines for green projects in those countries. It is expected that practitioners in developing countries will benefit from the outcome of this study.

Department of Civil Engineering Faculty of Engineering and Architecture Rajamangala University of Technology Isan Thailand Construction and Infrastructure Management Program Suranaree University of Technology Nakhon Ratchasima30000 Thailand School of Civil Engineering Suranaree University of Technology Nakhon Ratchasima30000 Thailand School of Engineering and Resources Walailak University Nakhon Si Thammarat80160 Thailand Swinburne University of Technology HawthornVIC3122 Australia Institute of Geotechnical Engineering Southeast University Nanjing Jiangsu210096 China

Sludge-fly ash geopolymer is a green material, which does not require cement as a cementitious binder. Sludge and fly ash (FA) are both by-products from Bang Khen water treatment plants and Mae Moh power plants, respectively. A liquid alkaline activator, L is a mixture of sodium silicate solution (Na2SiO3) and sodium hydroxide solution (NaOH). This article investigates the influence of compression energy (E) on the Unconfined Compressive Strength (UCS) of a novel sludge-fly ash geopolymer. The optimal liquid alkaline activator (L) content, sodium silicate solution to sodium hydroxide solution ratio (Na2SiO3/NaOH), heat temperature (T) and heat duration (D), providing the maximum UCS for each E is also investigated. Test results indicate that the optimal UFA ratio decreases as E increases. The optimal L/FA ratios for E = 592.5, 1346.6 and 2693.3 kJ/m3 are 1.5, 1.4 and 1.3, respectively. The Na2SiO3/NaOH ratio of 80:20 is considered as optimal for all E tested. The UCS of sludge-FA geopolymer at all E values tested increases with an increase of heat duration until a heat duration of 72 hours, after which the UCS becomes almost constant. The heat temperature accelerates the geopolymerization reaction and therefore enhances the strength. However, overheating results in micro-cracks in the samples due to the loss of moisture. As such, the optimal temperature is controlled by liquid content;the higher L/FA results in the lower optimal heat temperature. Since the optimal L/FA ratio decreases as E increases, the optimal T subsequently decreases with an increase in E;i.e., its values are 75, 85 and 95 °C for E = 2693.3, 1346.6 and 592.5 kJ/m3, respectively. The maximum UCS values of sludge-FA geopolymer at optimal ingredient and heat condition are 20, 18 and 16 MPa for E = 2693.3, 1346.6 and 592.5 kJ/m3, respectively, which meet the strength requirement of bearing masonry units as specified by the Thailand Industrial Standard (TIS).

Slope analysis regarding hillside development in Taiwan relies on manual calculations, which are time consuming and easily cause errors. This study used the AutoLISP application in AutoCAD plotting software to automatically export contour-line elevation information contained in image files. The slope analysis software developed in this study was then used to conduct slope analysis, which included automatically calculating the number of intersections between the four sides of a cadastral unit and the contour lines and computing the slope grade of the cadastral units. The software can assist developers in accurately evaluating the slope of a hillside, effectively increase the calculation speed, and can contribute to the process of hillside development. © 2014 ISSN 1881-803X.

The role of the corporation has shifted in a way that the public has come to expect more ethical accountability of business operations and responsibilities that branch beyond legal and economic responsibilities. However there is a lack of research that acknowledges how the international procurement of materials by construction companies exposes construction supply chains to ethical risks that may be attributed to the purchasing company. There is a need to consider the extent to which companies are responsible for the impact of their purchasing decisions upon international suppliers and if it warrants corrective action through corporate social responsibility. This paper answers this question and suggests a method by which construction companies may ascertain their responsibilities owed, formulate policy and implement their initiatives. It was found that the connected nature of the supply chains necessitates construction companies to analyse the extent of their influence in order to ascertain the level of responsibility. Strategies such as stakeholder management and strategic analysis are appropriate for companies to identify CSR policies whilst companies may enact their policies using codes of conduct. With high levels of public scrutiny and a reputation of social and environmental degradation the construction industry needs to consider how its actions impact external stakeholders such as international suppliers. This study therefore aims to outline a method by which construction companies can procure international supplies with due responsibility and accountability. © 2014 Springer-Verlag Berlin Heidelberg.

The use of probabilistic risk models for cost and schedule estimation and contingency calculation for large construction projects are becoming more common in recent times. Even in some cases, due to the push of funding agencies, they are becoming a requirement. Sophisticated bottom-up probabilistic models for contingency calculation uses formal risk analysis with probability concepts to model uncertainties and risk events, and incorporate the min the estimates of cost and schedule. Then, the necessary contingency budget is estimated based on the result at a desired confidence level, determined by the project sponsor, and its difference with the deterministic estimate. Such probabilistic models have a number of pair relationships that could be defined in the form of Pearson or Spearman's Rank correlation coefficient and they are assumed to have significant effects on the estimated contingency. Despite this fact, these relationships are largely ignored in many models developed for projects in the construction industry, assuming an independence that may not reflect reality. In this paper, the effect of correlation in contingency calculation of large construction projects is investigated. Four complex probabilistic models developed for risk assessments of actual large transit projects are examined under: 1) Assuming no correlation;2) Recognizing and incorporating correlations. Three different outputs are calculated in these models: 1) Pre-Award Contingency, 2) Post- Award Contingency, and 3) Total Project Schedule Contingency. The results show that consideration and inclusion of correlations in risk assessment models have a significant contribution in both Pre-Bid Contingencies and Post-Award Contingencies while they do not have significant impact on Project Schedule Contingency.

Pollution and consumption of water are important during construction activities and the life cycle of buildings. Promoting water efficiency in buildings supports the sustainable use of water. Green building certification systems award credits to these efforts. The LEED certification system is generally based on rules, codes and regulations that are in effect in the US. However, its credibility and popularity encourages professionals in other countries to use LEED too. For global consistency, United States Green Building Council (USGBC) is supporting regional approaches. Practitioners in some countries apply LEED as is and some have adapted it by considering regional differences caused by geographical location and local conditions. The "water efficiency" category accounts for approximately 10% of the points that a building can receive in the LEED system. In this study, the "water efficiency" category of LEED is reviewed with respect to its adaptation in developing countries. The ways water efficiency are achieved under different conditions than those in the US are explored. A review of water efficiency practices in India, Abu Dhabi, and Turkey is presented. Practitioners in developing countries are expected to benefit from these observations. Copyright © 2013 by Research Publishing Services.

Indoor air quality and thermal comfort are important considerations in green building design because they are related to users' health, comfort, environmental satisfaction, and productivity. In the Leadership in Energy and Environmental Design (LEED) certification system, the "indoor environmental quality" category covers air quality and thermal comfort and accounts for approximately 15% of the points that a building can receive for LEED certification;it constitutes the third biggest category among the seven major categories in LEED 2009 for New construction and Major Renovation. LEED is used in some countries as is, and is modified in some other countries to fit the local conditions. In this study, the "indoor environmental quality" category of LEED is reviewed with respect to its adaptation to local conditions in developing countries. The status of the codes, standards, and regulations in "indoor environment quality" in developing countries are investigated. Suggestions are made for an easier implementation of LEED requirements in developing countries. Copyright © 2013 by Research Publishing Services.

Sustainable building projects deal with a multitude of technical, environmental, economic, social, organizational, and innovation-related issues, to name but a few. Achieving sustainability goals depends on how well these issues are handled. While some sustainable building projects are quite successful, some are not. It is therefore important to learn lessons from past projects. This research aims to reveal the key lessons concerning sustainability-related issues in building projects. To that end, challenges in the achievement of sustainability goals of building projects are discussed, and lessons learned systems are examined. After that, the events experienced by project managers in a large number of sustainable building projects are obtained from a major public agency's website and are analyzed. The findings show the key lessons that have an important impact on the success/failure of sustainable building projects. The expected contribution of the study is to foster advanced solutions for future sustainable projects. © 2013 American Society of Civil Engineers.
