Abstract

The study addresses construction delays in the Aceh Tengah Regency POM Workshop project, valued at IDR 6,414,000,000 and spanning approximately 1,507 m2 across two floors. Motivated by the need for a comprehensive understanding of activity relationships and critical paths, the research aims to assess project duration, costs, and efficiency. Employing the Critical Path Method (CPM) due to data constraints, the study elucidates activity dependencies, network planning, and critical paths. Data collected from relevant stakeholders include schedule and cost budget plans. The analysis reveals a potential acceleration of 21 days, reducing the project duration from 126 to 105 days with a 99.74% probability. Cost control indicates an escalation to IDR 6,949,573,170.20 after calculating direct costs, with a daily increase of 0.92%. The findings underscore the significance of CPM in project management, offering insights into optimizing timelines and costs. The study highlights the importance of efficient project management methodologies in addressing construction delays and managing project budgets effectively.
