Analysis of Construction Time Acceleration Using the Crashing Method in the North Maluku Language Office Building Construction Project

Abstract

This study addresses accelerating construction time for the North Maluku Language Office Building using the crashing method. The project aims to provide adequate infrastructure to support linguistic and administrative functions, scheduled over 135 calendar days starting August 2024. Employing a descriptive quantitative design, the research involved direct field observations and Microsoft Project software to analyze critical path activities eligible for crashing. The population focused on all critical path tasks, with purposive sampling targeting those amenable to overtime acceleration. Data analysis included cost variance and percentage calculations for time reduction. Results show that applying overtime reduced the project duration from 67 days to as few as 44.67 days, with labor costs increasing between 6.7% and 26.82% depending on overtime hours. Cost and scheduling analyses facilitated selecting the most cost-effective acceleration scenario. The study concludes that the crashing method effectively balances time reduction and cost increments, serving as a practical strategy for managing delays in regional public sector projects. These findings provide critical insight for optimizing schedule compression while maintaining quality.
