COMPARISON OF SCHEDULING USING CPM AND PDM METHODS IN THE RECONSTRUCTION PROJECT OF JALAN BUMI MAKMUR – PULAU SARI, BUMI MAKMUR DISTRICT, TANAH LAUT REGENCY, SOUTH KALIMANTAN

Abstract

Construction projects in their implementation require the success of management because they are very important for the project. For a smooth work process, effective management is needed to manage project scheduling from start to finish. Therefore, in the Bumi Makmur – Pulau Sari Road Reconstruction project, scheduling will be made using diagrams with PDM, CPM, and modified CPM.

The Precedence Diagram Method (PDM) scheduling method in the construction industry is scheduling that can be done with several dependencies where there is  an overlapping relationship. While the Crictical Path Method (CPM) method, which is the dependence of finish to start work, then in this study will be modified, namely a work item is divided into several segments of work activities.

The results obtained from the research conducted on the scheduling of this project for the PDM method of the project can be carried out in 136 days. Meanwhile, the CPM method of the project can be done in 225 days and for the CPM method of project modification it can be done in 145 days. The three methods have critical paths, in PDM all activities have a critical path and only have 1 critical path, while in the CPM method without modification there is 1 critical path, and in modified CPM there are 2 critical paths.
