Analysis of Unit Price of Work and Implementation of Construction Projects Based on BOW (Burgerlijke Openbare Werken), SNI, and Field Project at BES Veteran Office Surabaya

Abstract

Cost estimation is a crucial aspect in construction project planning as it directly relates to efficiency, effectiveness, and project success. This study aims to compare the cost and time estimation results of reinforced concrete work using three methods: BOW, SNI 2008, and the Field Method. A case study was conducted on the construction project of BEST Veteran Office Building in Surabaya. The research method employed is descriptive-quantitative with a comparative approach. The findings show that the BOW method results in the highest total cost of Rp1.203.000 and the longest duration of 35,20 days. The SNI method produces the most efficient outcomes with a cost of Rp1.025.350 and a duration of 30 days. The Field Method lies in between, with a cost of Rp1.095.000 and a time estimation of 32,04 days, but is considered the most realistic as it is based on actual field data. In conclusion, the selection of estimation method should be aligned with project needs and characteristics to achieve optimal cost and time efficiency.
