Abstract

Efficient construction project management is crucial to ensure quality and timely completion within budget constraints, especially for large-scale infrastructure projects. This study examines the application of the Critical Path Method (CPM) in accelerating the construction schedule of the Malaka Regency Regent's Office. The project faced various challenges, including frequent delays caused by design changes, unpredictable weather conditions, labor shortages, and inadequate material or equipment supply. These challenges often disrupted the progress and efficiency of the project, necessitating an effective solution to mitigate potential time and cost overruns. To address these issues and align project progress with the original plan, CPM was utilized to identify critical paths, eliminate lag times, and optimize the overall project schedule. Using CPM analysis and Microsoft Project 2019 software, the project's original duration of 180 calendar days was successfully reduced to 100 calendar days. This acceleration was achieved by streamlining interdependencies between critical activities and optimizing work schedules without increasing project costs. The findings highlight the significant role of CPM in achieving time savings while maintaining the planned budget of IDR 94.59 billion. Moreover, this study demonstrates that proper scheduling, coupled with optimization techniques, can significantly enhance the efficiency and effectiveness of construction projects. These results underscore CPM's potential as a valuable tool for project managers to ensure timely completion without compromising quality or incurring additional costs. This research contributes to the growing body of knowledge in construction project management and offers practical insights for managing similar projects in the future

Abstract

The construction of the Malaka Regency Regent's Office has faced significant challenges, including frequent delays in project completion due to various factors such as design changes, unpredictable weather conditions, labor shortages, and inadequate materials or equipment. These issues have led to inefficiencies in time and cost management, emphasizing the need for effective project management strategies. This study applies the Critical Path Method (CPM) to analyze the project timeline, identify the critical path, and propose measures for project acceleration. By employing CPM, the project schedule was meticulously reviewed and optimized, resulting in a reduction of the initial planned duration from 180 calendar days to 100 calendar days. This acceleration was achieved by minimizing lag times between critical activities, reallocating resources, and implementing time-cost trade-off strategies, all without compromising the quality or scope of the project deliverables. The results demonstrate the effectiveness of CPM in streamlining construction project timelines and mitigating delays. Additionally, this study provides a practical framework for addressing time and cost overruns in construction projects, particularly in the context of public infrastructure development. By highlighting the integration of project management tools like CPM, this research contributes to the broader understanding of efficient scheduling practices and offers actionable insights for similar projects in the future.
