Abstract

Construction project delays are a common problem that directly affect time efficiency and lead to cost overruns. A similar case occurred in a warehouse construction project in West Karawang, which experienced a one-month delay due to unprepared field conditions and obstructed work access. This study aims to reduce time and cost overruns caused by these delays by using the Crashing Method, which accelerates work through additional labor. The analysis was conducted using Microsoft Project software to identify the project’s critical path. The results showed that the project duration could be reduced by five working days (4.21%), and costs were reduced by IDR 263,126,481.43 (2.02%) from the total normal cost of IDR 13,002,054,455.44. Activities classified as critical include 13 types of work, including roof trusses, roof coverings, and fascia painting. These findings confirm that the crashing method is an effective strategy for minimizing the impact of delays without sacrificing construction quality.
