Abstract

Road and bridge construction projects are inherently complex, requiring the integration of cost, time, and quality management. In practice, however, discrepancies between planning and implementation often result in delays and cost overruns. This study aims to evaluate the cost and schedule performance of the Subali Bridge Construction Project (D.G.008), Blitar Regency, Fiscal Year 2023, using the Earned Value Management (EVM) approach. The analysis relies on secondary data, including the Budget Plan (RAB), planned and actual schedules, and weekly progress reports. Key performance indicators assessed are Planned Value (BCWS), Earned Value (BCWP), Actual Cost (ACWP), as well as cost and schedule variances. Project performance is further examined through the Schedule Performance Index (SPI) and Cost Performance Index (CPI), along with final estimates of project duration and budget. The findings reveal cost efficiency, as indicated by CPI > 1, while SPI < 1 suggests potential schedule delays if corrective measures are not implemented. The study highlights the novelty of applying EVM to regional infrastructure projects in Indonesia, offering an analytical framework that functions as an early warning system for schedule risks and budget optimization. Beyond enriching construction management literature, the research provides practical recommendations for contractors, consultants, and local governments to enhance efficiency, accountability, and sustainability in infrastructure project delivery.
