Abstract

This research aims to analyze the comparison between contract prices and basic prices for structural and architectural works in the construction project of the Military Court Office Building III-19 Jayapura. This comparison is essential to ensure budget efficiency and to prevent budget misuse through unreasonable mark-up practices. The research employs a quantitative approach and the cost-plus pricing method, with data obtained from field surveys (primary data) and project documentation (secondary data). The results indicate a price difference of 2.4% for structural work and 10.4% for architectural work between contract prices and basic prices. According to the fair profit analysis based on the Ministry of Public Works Regulation No. 1 of 2022, most of the works fall within the acceptable profit margin of 10–15%. This study is expected to serve as a reference for future planning and control of construction project budgets.
