The purpose of Engineering Procurement Construction (EPC) general contracting project schedule management is to ensure that the project meets its deadlines, and it plays a critical role in contract performance. In comparison to the domestic general contracting model, project management and coordination are more complex for the general contractor of international EPC projects. As a result, scientific project schedule process control is critical to effectively ensuring project duration, saving project costs, improving project management level, and project quality, and ensuring that the project achieves the promised advantages for both the contractor and the owner. Through the research and analysis of the status of the schedule management of the Indonesia B Project Phase II cement project, corresponding optimization measures are proposed for the project schedule process control.
