Identification of high safety risks in box girder bridge construction to develop a safety plan for elevated railway projects

Indonesia is active in infrastructure development, especially the railway infrastructure. Currently, there are a lot of elevated railway construction projects and there are many construction accidents in elevated construction. Different construction methods in elevated construction lead to different safety risks. Therefore, it is necessary to identify safety risks, especially high risks. The main objective of this research is to identify high safety risks in box girder construction on elevated railway projects. This research was designed in 3 main stages, starting from risk identification, expert validation, and risk assessment survey. The main variable is the safety risk in box girder construction with launching gantry, heavy shoring, and cast in situ method. The project reviewed is the Double Track (DDT) Railway Project in Jakarta. The result of the analysis shows that there were some high safety risks in box girder construction with launching gantry method, heavy shoring method, and cast in situ method i.e. traffic accident, hit by heavy equipment, fall from a height, struck down by material, wire hanger broke, formwork collapse, heavy shoring collapse, heavy equipment overturned and collapsed and struck down by box girder. The result of this research can be a determinant in the development of good construction safety planning for the next elevated railway project.
