Comparative Unit Price Analysis of Reinforced Concrete Structures Pasar Inpres Painan Project Based on Actual Analysis and Standar Nasional Indonesia (SNI) Analysis

Abstract

Work concrete is a very important factor in development projects because this work has a larger volume than other work projects. The contractor must have more details inside analyze the price of unit work to get effective and efficient cost. Contractor often makes price cost analyses different from Standard National Indonesia (SNI), over cost or under cost. The contractor should analyze unit prices based on actual conditions to ensure a cost-efficient project budget. This research aims to count the total cost structure concrete reinforced (columns, beams, slabs) Pasar Inpres Painan Projects, Pesisir Selatan, West Sumatra, Indonesia with actual analysis and Standard National Indonesia (SNI) analysis. The Standard National Indonesia (SNI) method provides guidelines for calculating unit price analysis that develop standard national construction, with adapt conditions using AHSP 2023 published by the regulation minister of PUPR no. 8 in 2023. In the actual method, unit price analysis is based on index cost from daily project progress, including quantity and productivity. The results of the research, with actual methods analysis, obtained a total project cost of IDR. 10,979,791,988.17, with the column cost at IDR 2,064,056,033.12, the beam cost of IDR 5,864,218,409.93, and the slab cost at IDR 3,051,517,545.13. However, the SNI method showed the total project cost of IDR 15,371,771,346.57, with the column cost at IDR 2,877,891,431.64, and the beam cost at Rp. 7,877,841,167.72, and the slab cost at IDR 4,616,038,747.19. Hence the Actual method analysis showed that the total cost project is much cheaper than the SNI analysis, IDR 4,391,979,358.40 or 28.57. Analysis based on actual conditions project can be efficient, causing index cost from daily project progress including quantity and productivity, if workers increase, actual total costs will be efficient.
