  • A Literature Evaluation of the Energy Efficiency of Leadership in Energy
           and Environmental Design (LEED) -Certified Buildings

    • Authors: Mehdi S. Kaddory Al-Zubaidy
      Pages: 1 - 7
      Abstract: The Leadership in Energy and Environmental Design offers a means of certifying buildings that ensure environmental sustainability. Among the key areas evaluated for the certification is the energy efficiency of the design. Most of the studies selected showed that LEED certified buildings registered energy efficiency benefits. However, a few articles challenged these findings, citing that some LEED certified buildings did not show improvement in energy efficiency compared to non-LEED certified buildings. The disparity in study findings relates to the research design of the documents studied, the design-orientation of the LEED system, differences in occupancy numbers and building energy uses and the disparity in construction periods for the buildings under study.

  • Geotechnical Properties of Sub- Soils in Escravos Estuary, Western Niger
           Delta, Nigeria

    • Authors: H.O Nwankwoala; A.N. Amadi, T. Warmate, M. O. Jimoh
      Pages: 8 - 14
      Abstract: This study evaluates the sub-soil geotechnical characteristics at the onshore pipeline route at Escravos estuary, Western Niger Delta, Nigeria. Acquisition of soil samples for geotechnical studies was done by conventional boring method using light shell and auger hand rig. Samples were analyzed in the laboratory using standard analytical procedures. The samples explored showed a profile of very soft greenish dark grey and reddish brown clay formation. All samples observed confirmed this lithostratigraphy except for some of the grab samples. The entire formation generally, presents a low amount of organic content, low shear strength and high carbonate content. The unit weight showed an increase with high carbonate content. The samples gave a high amount of moisture content, higher than the liquid limit which indicates that on loading the pipeline route, the weight of the pipeline will dissipate a large amount of the pore water with a resultant increase in settlement. The pipeline should be placed on slippers pad at designated locations on the seabed along the survey route to avoid excessive settlement. This would distribute the anticipated pressure from the pipeline over a greater area and thus reduce the excessive settlement which is the characteristics of the very soft marine clay encountered in this investigation. The dimensions and bearing capacity of such slippers pads can easily be determined.

  • The Importance of New Technology for Delay Mitigation in Construction

    • Authors: Samad M E Sepasgozar; Mohamad Ahmadzade Razkenari, Khalegh Barati
      Pages: 15 - 20
      Abstract: Construction technology has a great potential to improve productivity and decrease project duration. Delay happens in many construction projects, although the priority of delay causes is different in various countries due to environmental effects. Delays can lead to considerable negative effects such as lawsuits between owners and contractors, loss of productivity and revenue, and contract termination. This paper presents key sources of construction projects delay in Iran, following a review of publications related to delay. In addition, the paper presents the relationship between new technology and time overrun in those projects. One of the main causes of delay in many projects is that they use an old generation of construction technologies; however, the role of technology adoption in delay is ignored. In order to collect first-hand data to explore the delay sources, experienced project managers of the residential and industrial projects were recruited. Experienced professionals from twenty six companies participated in this study. Seventy-three delay causes were identified in the sample projects, in which 25 factors were related to the new technology restriction. The result of the study assists policy makers and practitioners to understand the actual factors causing delay. The value of the study is that it investigates three main issues such as frequency of occurrence, degree of severity, and importance of each factor. Different than other studies, the paper focuses on technology attributes that may affect the project scheduling and time.

  • Factors Affecting on Productivity of Oil and Gas Construction Projects: An
           AHP Analysis

    • Authors: Khalegh Barati; Samad M.E. Sepasgozar
      Pages: 21 - 27
      Abstract: The oil and gas construction sector is one of the main industries all over the world which plays a powerful role in economic growth of all countries inasmuch as accounts 5 to 10 percent of Gross national product (GNP) of countries. Over the last decade, by considering the huge amount of money spent in constructing these kinds of mega projects, the issue of identifying affecting factors and their roles on productivity has become main challenge for engaging teams in the process of execution. In spite of its importance, no extensive and comprehensive researches have been yet conducted to assess the effective factors in productivity of these projects. This paper presents several factors affecting the productivity in the oil and gas construction projects. The paper also provides a priority list of important factors affecting the productivity based on a survey conducted in a large oil zone. Respondents involved in employer organizations, construction managers and consultants, contractor teams and university lecturers. Finally, through Analytical Hierarchical Process (AHP) and paired comparison between the effective factors and categorized groups, the importance and the effect of these factors on productivity of oil and gas construction projects were obtained. The result of the analysis shows that management factors are most effective factors while project’s factors do not have significant effect on productivity.
