Value engineering in construction is a process where the engineer or designer identifies the functions of a product or system and then finds ways to improve the value of that product or system. The goal is to improve the quality of the product or system while also reducing the cost. Value engineering can be applied to any stage of the design process, from the initial concept through to the final product. It is a systematic approach that considers all aspects of the product or system, including the materials, manufacturing, assembly, and installation.
