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.

Abstract

This study discusses the application of Value Engineering in the construction project of the Papua Regional Police Flats (Papua Regional Police Flats) located in Koya Koso, Jayapura City. The main objectives are to identify high-cost work items, propose more economical material alternatives without compromising function and quality, and determine potential cost savings. The research follows the five stages of Value Engineering: information, creative, analysis, development, and recommendation. The analysis revealed that floor slabs, columns, and beams were the most cost-intensive components. Through material substitution and technical-economic evaluation, several feasible alternatives were proposed. The total cost savings achieved from implementing these alternatives amounted to IDR 1,054,481,004.59. These findings demonstrate that Value Engineering can significantly improve cost efficiency in construction projects without reducing work quality.
