Abstract

Completing projects according to scheduled timelines and allocated budgets within implementation plans is a significant challenge facing engineering project management, including research and development projects, construction projects, and others. These challenges often stem from deficiencies in applying mechanisms for technical, temporal, and financial planning and monitoring. The Earned Value Management (EVM) methodology is considered a powerful and effective tool for addressing this deficiency by linking the actual progress of completed work with the time consumed and cost incurred, and comparing them to the project's planned baseline. This paper aims to highlight the critical importance of adopting the EVM method for monitoring the execution of construction projects and adopting it as a standard for evaluating cost and time performance. The paper provides a comprehensive overview of the key concepts and indicators in EVM, including Values of Planned, Earned, and Actual, Cost Variance (CV), Schedule Variance (SV) as well as performance indices (CPI, SPI) which reached 0.76 and 0.90 respectively, and forecasting indicator (EAC) which is 6.44 M Libyan dinar “increase by 31.8%”. The paper also analyzes the implications of these indicators in different project performance scenarios, emphasizing the role of EVM in enhancing transparency, identifying deviations early, and guiding corrective decisions to ensure the successful completion of projects. The scientific value of this study lies in the fact that it presents a rare case study in the context of infrastructure projects in Libya.
