Consequently, construction productivity has remained a major research area in the construction management discipline. Researchers from different countries have tried to identify the most important factors impeding productivity in construction projects. This continuous effort in this direction has produced a significant amount of research. The present study undertakes a comprehensive systematic review of mainstream studies on factors affecting activity-level construction productivity published in the last fifteen years (2001-2016). A total of thirty-six articles from different sources were identified and reviewed. The outcomes of this study would help researchers and practitioners by providing the findings of previous studies in a concise manner. It is further expected that the findings will help in directing a more focused approach on productivity improvement effortsenCopyright 2019 Advancement of Construction Management and Real Estate, CRIOCMconstruction industryconstruction productivityconstruction projectsConference paper2-s2.0-85069845243Baroudi, B.M.
