The goal of this study is to study the cost of safety system in building construction by studying multipurpose building with durable goods project. The cost of safety system in building construction is divided into two categories are the safety measure cost and the safety program cost in construction. From the study it is found out that the value of safety measure cost is approximately 1.85 % of a project cost and the value of safety program cost is approximately 0.98 % of a project cost. To sum up the cost of safety system in building construction is approximately 2.83 % of a project cost .Moreover the study found out that the safety measure cost is higher than the safety program cost about 1.88 as much. From the data of this study it can be used as the guideline in estimating the cost of safety system in building construction for the future project.
