Analysis of safety cost structure in infrastructure project of cable stayed bridge based on Work Breakdown Structure (WBS)

The development of infrastructure in Indonesia is currently quite massive, in accordance with the Government of Indonesia’s policy in accelerating infrastructure developments. However, along with the increase in the construction sector, work accidents in the construction sector also increased. Cable Stayed Bridge is one of the excellent technologies in connecting islands but has a high potensial hazards and risks and it can cause fatal accidents. Accidents can be prevented through a good occupational safety and health management system (OHSMS). The application of OHSMS financing in Indonesian construction sector, especially in the cable stayed bridge has not been clearly and measurably regulated. In its implementation, the existing regulations have not yet been fully followed by the construction actors. This study aims is to develop the safety cost based on Work Breakdown Structure (WBS). The research method are survey research and descriptive analysis. The study results are the cable stayed bridge standardized WBS, potential hazard sources, the preventive action to each potential hazards in each activity, finding the safety cost components based on WBS and the calculation of safety cost percentage in order to improve the OHSMS quality and reducing work accidents in the cable stayed bridge projects.
