Taking the commercial complex built on the 6# plot of Hengda Minjiang Xincheng as an example, this paper adopts the methods of interactive application and visual programming with various BIM software to study the application of BIM technology in different design stages of performance analysis, structural design and analysis, and design development for PC buildings for a commercial complex building. The studies fully embody the application value and broad prospect of BIM model in analysis and design, providing references for BIM technology application in design stage.
