The document discusses the application of value engineering in commercial building projects, emphasizing its role in enhancing value and reducing costs in the construction industry through systematic techniques. It outlines a three-stage methodology consisting of a pre-study, value study, and post-study, which aims to identify functions, eliminate unnecessary costs, and implement recommendations for improvements. The historical context and literature review highlight the evolution and effectiveness of value engineering in various project phases, ultimately promoting a holistic approach to achieving optimal project outcomes.
