Application Of Value Engineering in a Three-Storey Building Construction Project
Main Article Content
The Three-Story Building Construction Project functions as a souvenir shop with a project value per m2 of Rp 9,962,985. Research conducted by Atmaja (2023) on the construction project of the Bali Land Transportation Education and Training Center Administration Building was carried out for cost efficiency because the project cost per m2 was 4,143,968. Therefore, a review was conducted using the Value Engineering (VE) method to reduce costs without reducing the function of the building. The purpose of this study was to analyze structural and architectural work items with value engineering and analyze the amount of cost savings. VE consists of 6 stages: the information stage, the function analysis stage, the creative stage, the evaluation stage, the development stage, and the recommendation stage. The information stage was carried out by collecting information about the project, followed by a Pareto diagram which was used to find 20% of work items that produced 80% of the total project cost, then those items were analyzed. The function analysis stage was carried out using the FAST Diagram (Function Analysis System Technique) to determine the main function of each item. Furthermore, the creative stage produced several alternative designs as a replacement for the initial design. In the evaluation stage, SAP2000 was used for structural analysis and Analytical Hierarchy Process (AHP) was used to determine the best alternative. The development stage was conducted with technical analysis and Life Cycle Cost (LCC) calculations. Furthermore, in the recommendation stage, the results of the VE analysis of the evaluated alternatives were reported. The results of the VE analysis showed that savings could be made on structural work by replacing the initial design of composite beams and columns with conventional beams and columns, and on architectural work by replacing red bricks with lightweight bricks. Thus, the percentage of savings on structural work costs was 37.1% and walls 3.516% of the initial RAB.
