Cost Acceleration Analysis Using the Critical Path Method (CPM) and Time-Cost Trade Off (TCTO) on the Malaka Regency Regent's Office Construction Project

Abstract

The construction of the Malaka Regency Regent's Office has faced significant challenges, including frequent project delays due to various factors such as design changes, unpredictable weather conditions, labor shortages, and inadequate materials or equipment. These issues have caused inefficiencies in time and cost management, highlighting the need for effective project management strategies. This research applies the Critical Path Method (CPM) and the Time Cost Trade Off (TCTO) Method to analyze the project timeline, identify the critical path, and propose measures for project acceleration. By using CPM and TCTO, the project schedule was meticulously reviewed and optimized, This research applies the Critical Path Method (CPM) and the Time Cost Trade Off (TCTO) Method to analyze the project timeline, identify the critical path, and propose measures for project acceleration. By using CPM and TCTO, the project schedule was meticulously reviewed and optimized, The cost acceleration needed to complete the expedited construction project ofthe Malaka Regent's office is IDR 55,681,744,240.39. The acceleration of the implementation using the Critical Path Method (CPM) resulted in this amount, while the cost acceleration using the.Time Cost Trade Off (TCTO) method with the alternative of adding work shifts and overtime resulted in an amount of IDR 54,681,774,240.39.Based on the research results, the following suggestions can be considered for future researchers: it is necessary to use other acceleration methods, not just the time and cost acceleration methods with the Critical Path Method (CPM) and the Time Cost Trade Off (TCTO) method.The results show the effectiveness of CPM and TCTO in streamlining construction project schedules and reducing delays. Additionally, this study provides a practical framework for addressing time and cost delays in construction projects, especially in the context of public infrastructure development.
