Construction Project Evaluation Using CPM-Crashing, CPM-PERT and CCPM for Minimize Project Delays

Abstract

This research conducted in one construction company in Indonesia, the company was facing several problems, many projects that already ended have delays. Overdue payment one of the projects can reach Rp 252.544.148.-. For calculating late payment that the company can save researcher using Critical Path Method (CPM)-Crashing. CPM-Crashing method can accelerate project duration by increase resource budget, so company doesn't need to pay overdue payment. The result of CPM-Crashing is company can save Rp. 227.584.147.-late payment. To anticipate project delay proper planning is required. One of project planning method is project scheduling. Great loss because of the overdue amount, the company must evaluate their project schedule. The Researcher using CPM-Project Evaluation Review Technic (PERT) and Critical Chain Project Management (CCPM) both methods can give new project schedule. CPM-PERT can give probability project finish and CCPM can give new project schedule. The result of this research is probability project is not delay is very low that is only 55% project can finish on time, the company must try CCPM schedule.
