Abstract
In the development of healthcare infrastructure projects, hospitals play a critical role and frequently encounter challenges in managing time and cost, including risks of delays and cost overruns. This study aims to analyze the performance of the Critical Center and Support Services Building construction project at Dr. Moewardi General Hospital Surakarta using the Earned Value Analysis (EVA) method, as well as to optimize time and cost through the Time Cost Trade Off (TCTO) method. The results of the EVA show that the project experienced schedule deviations from the initial plan. In the 16th week, the CV was Rp0,00 and CPI was 1,00, indicating that the budget aligned with the initial plan. However, the SV was (-)Rp4.474.490.995,78 and SPI was 0,84, indicating a delay in project implementation. The estimated cost to complete the project from week 16 was Rp67.574.741.112,50. A calculation in the 19th week also showed that the budget remained on track, although the project continued to experience delays. Subsequently, TCTO optimization was carried out using several alternative scenarios on critical path activities, including adding 1 hour, 2 hours, and 3 hours of overtime. Using Primavera P6 software, crash duration and crash cost were calculated for each scenario. The optimization results showed that the scenario of adding one hour of overtime was the most efficient, as it accelerated the project with an additional cost of Rp12.043.259,31 a cost efficiency of -0,013%, and a reduction in project duration by 6,05 days with a time efficiency of 3,071%. This research demonstrates that the combined application of EVA and TCTO methods can effectively support project completion on time and within a reasonable budget.
