Analisis Percepatan Waktu Pekerjaan Rigid Pavement Menggunakan Critical Path Method (CPM) (Studi Kasus: Proyek Pembangunan Jalan Kawasan Heartful Town Depok)

Abstract

Road construction projects often encounter delays, particularly in rigid pavement development, where precise scheduling and execution are essential. The Heartful Town Road Construction Project in Depok experienced delays due to limited control over critical activities and the absence of scheduling analysis using the Critical Path Method (CPM). This study aims to evaluate project acceleration through CPM and crash duration analysis. Data from the project management team were used to build a work network and determine the critical path. Two acceleration strategies were examined: extending working hours and increasing workforce allocation. Results showed the initial project duration of 130 days was reduced to 127 days with one hour of daily overtime, and to 114 days with three hours of overtime. Alternatively, increasing the workforce by 50% on critical activities shortened the subbase layer from 33 to 18 days, compaction from 21 to 14 days, lean concrete casting from 28 to 15 days, and rigid pavement casting from 42 to 27 days. These reductions produced a total critical path duration of 80 days. The findings highlight that combining CPM with crash duration methods, either through overtime or additional workers, effectively accelerates project completion without changing the activity sequence.
