Value engineering is an effective approach used by many industries that aims to analyze a product or project to optimize it while reducing costs. VE does not just focus on cost reduction; its purpose is functional cost-effectiveness. This project presents the five phases of the VE process: information, creative, evaluation, development, and report applied to a construction project. A case study was performed on a 5-mile stormwater drainage tunnel where the original design includes two different cross-sections to be excavated using a tunnel boring machine. The alternative was proposed by the contractor, and it resulted in a solution that provides the following advantages: improved schedule, cost savings, add functionality, and simplifies operation and maintenance in the long run. This alternative result in a cost-saving of $1.4 million. VE analysis developed by the builder or the contractor adds significant value or advantages to the project due to its expertise in construction methods.
