The Critical Path Method in Construction Project Rescheduling

Abstract

Generally, Projects have a deadline, which means the completion of the project must be on time because the successful implementation of a project is an important goal for both the project owner. Management involvement is required for executing the project more effectively and efficiently from the beginning of the task, project completion time and cost. The program needed to project scheduling, project completion time and cost. The problem discussed in this study is the CPM calculation result using Microsoft Project, how to identify the critical path and float in each activity with the CPM. The purpose is to obtain the results of time scheduling calculations using Microsoft project-based CPM, to analyze the critical path of the CPM, and to find out activities that have a grace period. Based on shop drawing, SNI analysis is carried out which is the starter to make project schedules with duration calculated from SNI analysis. The calculation result and data input carried out in Microsoft Project create 180 workdays with 22 activities are on a critical trajectory which takes 20,635 hours. After the authors reschedule the project implementation lasted 172 working days, there were 7 activities on the critical trajectory, spending 18,339 hours.
