Construction industry is an intensive labor oriented industry, the level of productivity and performance of labor is a crucial factor for any project success. The research presented an overview for different definitions and concepts of construction productivity in the existing literature. It tried to investigate the recent methods, approaches, and levels for measuring labor and construction productivity and performance in current literature. In addition to a critical comprehensive review for factors affecting labor productivity in different countries, followed by an analysis for 6 case studies, in which cross case analysis for three case studies related to developed countries has been done, and the same process for three case studies related to developing countries, in order to detect the critical common factors affecting labor productivity for each developed and developing countries. Next step was an analysis for two case studies for how labor productivity can be measured and reported at construction sites, one case study illustrated the implementation of activity sampling technique to measure the productivity rate and the distribution of time spent of labors for block work activity, furthermore, the other case study revealed difficulties in choosing consistent construction metrics for output and lack of consensus for standard units. The research aimed to explore the different ways to improve the labor productivity in developing countries to meet the productivity level of labors in developed countries by applying best practices of site management principles presented in two case studies associated with author experiences and existing literature.
