Implementation of Value Engineering in Construction Projects Based on Building Information Modeling (BIM) Case Study: Factory Construction Project in Cikarang, West Java

Abstract

The application of Value Engineering (VE) integrated with Building Information Modeling (BIM) represents an innovative approach to improving cost efficiency and functional value in construction projects. This research aims to examine the integration of VE and BIM in a factory construction project in Cikarang, West Java, focusing on the analysis of the main steel structural element (rafter) to develop a more economical design alternative without compromising quality and functionality. The research methodology includes functional, creative, and evaluative analysis stages, along with the application of Life Cycle Cost (LCC) as a basis for decision-making. The study findings indicate that the alternative design using Castellated Beam provides significant cost efficiency. The material volume is reduced by 64,568 kg, and the initial construction cost decreases by 53.69% compared to the original design. Overall, the total project cost savings reach 3.00%. The LCC analysis further demonstrates long-term savings of 50.07% over the project’s lifecycle. Although the salvage value of the alternative design is lower, its advantages in initial and maintenance costs yield greater economic benefits. BIM technology at the 5D level proves effective in enhancing the accuracy of quantity take-offs and cost estimation, while also enabling efficient visualization of design alternatives.This study concludes that the integration of VE and BIM is an effective strategy for improving cost efficiency and design decision quality. Castellated Beam is recommended as an optimal solution for similar projects, and the implementation of VE based on BIM should be expanded to other construction elements to maximize overall project value.
