Analysis of Material Distribution Delays on Cost and Time Performance

Case Study: Kasai – Semanting Road Construction Project, Berau Regency

Abstract

This study aims to analyze the impact of material distribution delays on cost, profit, and project completion time, using a case study of the Kasai–Semanting Road Construction Project in Berau Regency. A reduction in effective working hours due to material distribution delays was found to significantly affect project cost increases, profit decreases, and extended project duration. The analysis revealed that when effective working hours decreased from 6 hours to 4 hours per day, the project cost rose from IDR 10.57 billion to IDR 15.58 billion, while profit dropped from IDR 8.60 billion to IDR 3.59 billion. Furthermore, the project completion time increased from 180 days to 270 days, indicating a delay of 90 working days. These findings underscore that material distribution delays can disrupt the overall efficiency and success of a construction project. Therefore, timely logistical planning and material distribution management are essential to maintaining control over costs, profits, and project schedules.
