The Coal-Fired Steam Power Plant development project has crucial role in encouraging economic growth. The Coal-Fired Steam Power Plant is a complex EPC project that often experiences delays in its completion. The factors that affect the delay are a change in scope, reworking, and lack of coordination. The delay of this Coal-Fired Steam Power Plant project can be overcome with a clear scope through the approach of project management tools, called WBS. This study aims to the development of risk-based standardized WBS for civil and structural works of Coal-Fired Steam Power Plant construction projects in Indonesia. Work Breakdown Structure is a decomposition of activities so that the project is easier to manage and it can increase the probability of project success. The development of WBS standards uses survey methods and expert validation including risks monitoring that affects project time performance. The WBS standard consists of the work package, method, activity, labor, material, and equipment resources.
