Abstract

This study investigates the cost implications of accelerating the construction of the Trenggalek Religious Court Office Building in response to delays caused by flooding. Utilizing the crashing method, two acceleration strategies were evaluated: adding overtime hours and increasing workforce. The results indicate that reducing the project duration from 240 days to 180 days through overtime incurs a cost increase primarily due to additional pay, while reducing it to 170 days by adding workers results in higher labor costs. Detailed analysis of durations, costs, and cost slopes for each activity provides valuable insights for project managers to select the most cost-effective acceleration approach. Additionally, a comparative analysis of normal and crashing schedules for various construction tasks highlights potential efficiencies in scheduling and budgeting, ultimately aiding in timely project completion within optimized costs.

Abstract

This study discusses several ways to accelerate the building construction process. The study used two methods, namely crashing and overlapping. The crashing method involves adding overtime hours and labor to shorten the project duration. Meanwhile, overlapping is rearranging the relationship between tasks so that they can be done simultaneously without reducing the initial time, thus accelerating completion at a relatively comparable cost. The analysis results show that both methods are effective in accelerating projects, with the overlapping method requiring less cost and providing greater time reductions. The choice of the best method depends on budget constraints and the project's completion time requirements. Thus, this acceleration strategy can help project management in achieving time targets at an optimal cost.
