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.
