Data-Constrained Project Monitoring: A Budget-Based Earned Value Management Framework for Road Infrastructure Performance

Abstract

Time and cost control are critical factors in ensuring the successful delivery of construction projects, particularly for road infrastructure projects with relatively short durations and limited resources. This study aims to evaluate the implementation performance of a road improvement project using the Earned Value Management method based on planned schedule data and physical progress reports. A quantitative case study approach was employed, in which the analysis utilized Planned Value, Earned Value, and Actual Cost parameters through a budget-based Earned Value Management approach due to the unavailability of detailed cash-out data. The results indicate that the project Budget at Completion was IDR 162,087,328, with cumulative Planned Value and Earned Value of IDR 73,409,351 (45.29%) in Week 1 and IDR 162,087,328 (100%) in Week 2. The Schedule Variance was equal to zero and the Schedule Performance Index was 1.00 throughout the observation period, indicating that the project was executed fully in accordance with the planned schedule. From a cost perspective, the budget-based approach resulted in a Cost Variance of zero and a Cost Performance Index of 1.00, reflecting conformity between realized work value and the planned budget. This study concludes that budget-based Earned Value Management can serve as an effective tool for evaluating schedule performance in construction projects under conditions of limited cost data availability, although a more comprehensive assessment of cost efficiency requires detailed actual cost information.
