Abstract

Evaluation of the final project cost and time estimates is essential to measure whether the project can be completed in accordance with the previously established budget and schedule. The calculation of the final cost and time estimates for the rehabilitation project of the Segiri Sports Hall Building in Samarinda City uses the Earned Value Method (EVM). The evaluation is performed by calculating the Estimate At Complete (EAC) for cost projection and the Estimate At Schedule (EAS) for the project completion time estimate. The analysis results show that the EAC experienced fluctuations, starting from Rp 44,648,760,330.58 in the first week of July and increasing to Rp 52,630,845,855.14 in the 15th week of November. This change was influenced by the increase in the Actual Cost of Work Performed (ACWP), which reached Rp 31,173,250,000.00 in the 15th week, as well as a decrease in the Estimate To Complete (ETC), reflecting cost adjustments. Although the EAC showed an upward trend from July to October, there was a decrease in November, indicating an improvement in project cost management. In terms of time, the EAS shows that the project was running ahead of schedule from the first to the third week, with EAS values ranging between 16.57 and 16.41. However, starting from the 4th to the 6th week, the EAS increased significantly, reaching 28.80 in the 6th week, reflecting a delay. Although there was a decrease in the EAS in the 14th and 15th weeks, the project still showed a significant delay compared to the planned schedule. These findings emphasize the importance of further evaluation in time management and resource allocation to minimize delays and ensure the project is completed on target.

Abstract

The analysis performed to optimize costs will generate alternatives that will be compared with the initial design, and this analysis can be called value engineering analysis. This research aims to assess the percentage of cost savings that can be obtained by applying the value engineering technique, as well as to evaluate the life cycle cost of various selected material alternatives. The Mosque Construction Project in the South Kalimantan Provincial Government Office Area was chosen as the research object because of cost inefficiency in the architectural work, with a total cost of Rp. 26,857,215,362.63 out of the total project cost of Rp. 55,600,738,764.97. The architectural work will be corrected using Pareto diagram analysis through the value engineering phases, namely the information phase, speculation phase, and analysis phase. From the value engineering analysis results, a savings of 3.65% of the total project value was obtained. The life cycle cost analysis shows that the selected material has a lower life cycle cost value compared to the initially planned material. In addition, the work execution time with the selected material can complete the work on site more quickly
