Research on the Development Strategy of Prefabricated Construction under Industrialization Trend

Research purposes: Through the application of BIM technology and TOPSIS method to take prefabricated construction as the research object, this paper analyzes the problems of high construction cost, information technology limitations, imperfect industrial chain and other problems in the process of industrialization of China's construction engineering, solves the adverse factors affecting the development of prefabricated construction, and puts forward the strategy for the development of prefabricated construction in China. Research conclusions:(1)The forward design method based on BIM technology can improve the repetition rate of construction components in the project design stage, reduce the types of prefabricated construction components and effectively reduce the construction cost. In the construction stage, the collaborative management of project participants can also be realized, which is conducive to improving the production efficiency. (2)The application of TOPSIS method in the partner selection of prefabricated construction industry chain can provide a basis for the multi-objective decision and management of the project, which is conducive to the collaborative work among industrial chain partners. (3)During the whole life cycle of the construction project, the collaborative management system based on BIM technology and the industrial chain partner selection based on TOPSIS method can help to promote the deep cooperation among the industrial chain enterprises of prefabricated construction and promote the development of prefabricated construction. (4)The research results can provide references for the industrial construction of residential buildings, subway stations and railway stations. © 2020, Editorial Department of Journal of Railway Engineering Society.
