Abstract. In the last five years in Indonesia, the toll road construction project has become one of the most massive developments, with 65 toll roads and 4 national roads included in the National Strategic Projects list (PSN). However, along with the increase in construction projects in Indonesia in general the number of work accidents has also increased. in the period of 2017 to 2019, 54.5% of the number of construction accidents came from toll road projects. This results in significant losses such as loss of life, time, cost and so on. Wirahadikusumah (2019), the aspect that can improve working safety conditions is the availability of a decent budget and specifically allocated for the implementation of SMK3 in construction projects. Rzvi and Elnathan (1999), Activity-Based Costing method can provide information on neglected cost items in the construction method. So that OHS cost information on road construction projects can be available accurately starting from defining work activities based on Work Breakdown Structure (WBS). The research method used is archive analysis, surveys involving construction experts, and previous project case studies. This study produces a ratio of OHS costs to contract values in road construction projects so as to improve work safety.
