Steel structural projects is a relatively special field of construction projects which is concerned with the design and installation of different project elements according to various purposes and it is differ from conventional structural engineering projects mainly in the special problems that have to be considered during construction, transportation, installation, and operation. There are many factors that impact the crew productivity in this field. The purpose of the study discussed in this paper is improving the crew productivity for the construction of steel structure projects. The research was conducted by personal interviews, literature review, researchers’ knowledge, telephone calls and correspondence via an email. It was designed model on Matlab in measuring and evaluation the crew productivity of construction of steel structure projects based on the several factors that affect the construction of steel structure process. It is recommended that contracting and consulting firms to improve the crew productivity for the construction of steel structure projects before starting and during the construction of projects. The construction industry can use the findings in this paper as a basis for improving the crew productivity for the construction of steel structure projects.
