Abstract: The Sanyuan Road project in Jiaxing adopts a BIM comprehensive application mode based on EPC for the entire process of design and construction, combines with the custom development of BIM software and collaborative platform, which realizes the dynamic and gradual integration of BIM models and information. At the same time, the BIM application promotes the optimization of the design process and improves the construction process management. Eventually, based on the EPC+BIM mode, the problems of project information integration between design and construction process have been solved effectively.
