Analysis of the Performance of the HDPE Pipe 450 Installation Project in Relation to Cost and Time Using the Earned Value Method

Construction project work requires regular monitoring to determine project performance based on the work that has been realized. The purpose of this study is to evaluate cost and time performance while estimating the time and cost of completing the drainage pipe project for each reporting period. In this study, the Earned Value Method is used to measure performance by comparing planned work with realized work, as well as the actual cost of the work. The results of the 12th week of research showed that the cost of project implementation was lower than planned, as indicated by the Cost Variant value of +117,923,808.28 (1.37%), Cost Performance Index of 1.01 (> 1), Schedule Variant of +1,731,414,451.68 (20.08%), and Schedule Performance Index of 1.25 (> 1). The results of the above indicators indicate that the project was implemented faster than planned. The results of the calculation of the estimated time for the first to third weeks remain consistent with the plan, which is 14 weeks, while for the fourth to twelfth weeks it is lower than planned. The results of the cost evaluation show that from the first week to the fifth week, the average final cost of completing the project was 102.54% higher than the planned budget, while from the sixth week to the twelfth week, the final cost of the project was 90.01% lower than the planned budget of 100%.
