The growth in the number of construction laborers has been complemented by the magnitude of the value of completed projects, especially in the field of civil construction. Therefore, the construction cost analysis is crucial to improve the efficiency and effectiveness of enhancement activities in this sector. This research paper presents a comparative analysis of labor wage cost between the Unit Price Analysis of Work (UPAW) in comparison to the on-site study of contractor cost calculation. This study analyzed the secondary data of UPAW based on Standar Nasional Indonesia in terms of daily labor productivity and wages of on-site masonry, plastering, and tiling works for a two-floor block school for a 6-day working period in Banda Aceh, Indonesia. The results showed that the yielded area was 1622.31 m2 for the particular block with new averaged labor coefficients ranging between 0.235 to 0.626 (general worker), 0.075 to 0.279 (craftsman), 0.01 (head handyman), and 0.015 (foreman) for on-site works. The calculated labor wage cost for the on-site study was then decreased in comparison to the value stated in the contract. The laborers received less wages (1.10% to 1.25%) for wall masonry, plastering, and tiling work. These cost discrepancies could lead to budget overruns, project delays, and financial losses, affecting the entire success of construction projects.
