  7. Abstract:
  8. The current global economy challenges and the importance of maintaining a sustainable development strategy has increasingly bolded the importance of construction productivity measures. This research describes the results of a running research that is to find the most critical factors affecting the productivity of high rise concrete building projects in developing countries. To achieve that, we have conducted Delphi method in two phases. In the first phase we had a brainstorming program with construction experts from owner organizations, construction contractors and designing engineers to identify factors that have influenced productivity in recent concrete building construction projects.50 Factors extracted from the first phase were sorted in 4 categories: technical factors,financial/economic factors,contractual/legal factors and environmental/cultural factors.In the second phase, these industry-based recommendations were tabulated in questionnaires in order to statistically determine top ten factors influencing productivity of the high rise concrete building construction projects in developing countries. The research shows that: deficiency in concrete mixture, pouring and curing technology, un-availability of appropriate material and information, lack of proper allocation of skilled labors, absence of constructible designs are among the top 10 factors affecting high-rise concrete building construction productivity in developing countries. Another result of this study is introducing a new section to be added in the organization chart, called “Productivity Improvement Office” that sounds great according to the experts’ opinions.
