Steel structural projects are relatively special field of construction projects. The steel structure projects differ from conventional structural engineering projects mainly in the special problems that have to be considered during construction, transportation, installation and operation. The productivity improvements are attributed to the technology advances in equipment and construction methods over the last two decades. Steel structural projects are a relatively special field of construction projects. There are many factors that impact on productivity in this field. The construction industry especially the construction of steel structure projects is rated as one of the key industries. It helps in developing and achieving the goal of society. Study and knowledge of construction productivity are very important because they influence the economics of the construction industry; this is because prior knowledge of crew productivity during construction can save money and time. Investments for these projects are very high and because of the complexity in construction of steel structure projects, various factors can highly affect overall productivity, thus the project can end up adding even more time and money in order to be completed. The main purpose of this paper is present a methodology for modeling on Mat lab to construction performance control for construction process of steel structure based on the several factors that affect the steel structure processes. The Mat lab model is used for controlling on construction productivity of steel structure projects. The construction industry may use the findings of this paper as a basis for controlling and improving productivity and construction performance for the construction of steel structure projects. The ability of the estimating team to accurately determine productivity for different activities will have a significant impact on crew cost component, time schedule of the project and improve projects’ performance. The use of the Mat lab model is expected to result in savings in cost and time schedule of construction of steel structure projects as well as savings in the cost of the overall project.
