Construction projects play an important role in supporting infrastructure development. However, there are often deviations between the initial plan and actual implementation, either in terms of money or time, which can result in delays and cost overruns. This study aims to examine the implementation of the Earned Value Concept Method in controlling costs and time on the Trasan II Bridge Replacement Project in Klaten Regency. The study results prove that until week 15, the project has exceeded the plan target with a realization of 81.38%, higher than the plan of 35.21%. The SPI of 2.207813348 indicates a time performance that is ahead of schedule, but the CPI of 0.995142328 indicates the costs incurred exceeded the plan budget. The projected remaining cost (ETC) is Rp701,350,409.24, and the remaining completion time (ETS) is estimated at 4,759 weeks. In addition, analysis using the Precedence Diagram Method (PDM) identified a critical path involving seven activities with a total duration of 21 days. Rescheduling was carried out to optimize project implementation. This study provides recommendations to improve project management efficiency through periodic performance evaluation and integrated control using the Earned Value Concept Method.
