The plan for the Cost implementation of Construction Safety Management System in the Public Works and Housing Ministry sector is part of the Construction Safety Plan, which is agreed upon and approved at the preparatory meeting for the implementation of construction work (Pre Construction Meeting). This study aims to identify and analyze the cost structure of safety in high residential buildings in Indonesia. The methodology used in this study is to use Bill of Quantity data from 16 projects in various regions in Indonesia and then analyzed using the Monte Carlo software to determine the optimal cost of safety. The results of this study indicate that the component of expert consultation related to construction safety is the least priority component, followed by the insurance and licensing component, then the construction safety personnel component which is not prioritized. For the construction safety personnel component, according to the construction cost budgeting, the personnel cost has been included, so that it is no longer budgeted for construction safety costs.
