Abstract

Purpose: Along with advance era and technology, tunnel construction is the alternative infrastructure that can be used as an option, especially in difficult terrain conditions. The tunnel work project is a series of very complex activities. Work activities that are not supervised, causing the risk of these activities neglected. This has become one of the causes of workplace accidents. The risk of work accidents can be prevented by early identification and analysis of potential hazards in each of the activities listed in the project WBS. Therefore, the existence of WBS is needed in presenting a risk assessment, probability and impact arising from the work accidents. The aim of this study is to develop a standardized WBS for safety planning on tunnel construction work based on risk. The standardized WBS will be a main input for identify potential hazard risks and producing risk responses. Methodology: The method that will be used in this research is a qualitative approach with a survey and deep interview to experts. Results: The results of this study are standardized WBS, potential hazard risks and the developed of WBS standard for safety planning, as a step to prevent work accidents in tunneling work projects. Applications/Originality/Value: The implementation of this research is for the contractors who are required to make safety plan, especially in tunneling work projects.
