Analysis of Cost and Schedule Variances Using Earned Value Method on Waru - Buduran Frontage Road Bridge Construction Project

Abstract

Infrastructure development is an important element in supporting economic growth, including in Indonesia. The Waru - Buduran Frontage Road Bridge development project was designed to overcome traffic congestion in the Sidoarjo area as a buffer zone for Surabaya. However, the project faced various obstacles, including schedule deviations and significant costs. This research aims to analyze the project's cost and schedule performance using the Earned Value Analysis method, focusing on Schedule Variance and Cost Variance to identify the main causes of delays and cost inefficiencies and provide recommendations for improvement. The research method used was a descriptive quantitative approach, with data collection through documentation of project financial reports, weekly schedules, and interviews with project managers. The analysis was carried out by calculating EVA indicators, such as Planned Value, Earned Value, and Actual Cost, to evaluate the cost efficiency and timeliness of the project. The results showed that the project experienced a negative schedule deviation of -9.911% in the 14th week, caused by technical constraints in utility relocation and coordination between stakeholders. However, the project still showed cost efficiency with a positive Cost Variance of 3.8%, indicating that actual costs were lower than the planned budget. The implications of this research highlight the need for more effective schedule planning, improved project coordination, and the implementation of acceleration strategies to reduce the impact of delays. In addition, the integration between schedule and cost management must be improved so that cost efficiency does not compromise the continuity of the project schedule.
