Value engineering is a technical and economic analysis method used to analyze the relationship between product function and cost, so that it can reliably realize the necessary functions of products with low total cost, so as to improve the value of products. Through the relationship between function and value, the close combination of technical problems and economic problems is a management method to realize the necessary functions of products with the lowest product life cycle cost. Generally speaking, there are five ways to improve the value of products: one is to improve the function and reduce the cost, which is the most ideal way. Second, the function remains unchanged and the cost is reduced. Third, keep the cost unchanged and improve the function. Fourth, the function decreased slightly, but the cost decreased significantly. Fifth, the cost is slightly longer, but the function is greatly improved. Using the principle of value engineering, make scientific decision on the scheme on the basis of scientific analysis, and select the design scheme that is technically feasible and economically reasonable. The main characteristics of value engineering are: starting from the functional needs of users, carry out functional analysis on the research object, make the design work achieve the unity of function and cost, and reduce the cost on the premise of meeting the functional requirements. The construction land of Huasi community of Baoshuo group was originally a chemical plant with serious soil pollution, which requires deep foundation construction. It is suggested to design the basement. At the beginning, the commercial facilities near the street did not consider the basement, which not only wasted the deep foundation, but also carried out a large amount of earthwork backfilling. Through consultation with the design unit, the basement was added and provided warehouses and rest places for businesses. It was very popular and sold at a higher price than residential buildings. The cost is not very long, but the function has been greatly improved.
