<p>This study examines the implementation of unit price contracts with hypothetical volumes in Surface Maintenance Operation (SMO) Earthwork service projects, where quantity uncertainty may significantly affect project cost performance. The objective of this study is to evaluate cost efficiency and analyze the financial impact of quantity realization under unit price contract schemes. A quantitative approach was employed using completed contract data from Package X and Package X Mitigation. Cost efficiency was assessed through Cost Performance Index (CPI), Budget Variance (BV), and variance-based analysis using Budget Plan (RAB) and Final Budget Plan (RAPP) data. The results indicate that CPI and BV effectively measure cost efficiency and identify deviations between planned and actual expenditures. The analysis further reveals that quantity realization and changes in work volumes are major factors influencing contractor profitability and project cost performance. The mitigation package demonstrated a more balanced operational distribution and improved cost control compared with the original package. The study concludes that integrating CPI, BV, and variance based analysis provides a practical framework for evaluating post execution cost efficiency in unit price contracts with hypothetical quantities. These findings support evidence-based cost management and contribute to SDG 9 and SDG 12 through improved resource efficiency and sustainable infrastructure project management.</p>
