Chongqing Zhongke Mansion is the first domestic building adopting steel tube confined concrete outer frame-core tube structure system in China, and its external wallboards are prefabricated plain concrete sandwich wall panels. The Zhongke Mansion is a national demonstration project of fabricated building technology, with a total floor area of 38, 000 square meters and an assembly rate of 61%. The project adopts EPC general contract mode and the BIM technology is used as the main technical means of project management to ensure the successful implementation of the project. This project adopts BIM technology to carry out parametric design, collaborative design, pipeline comprehensive design, 3D scanning quality control, detailed design, construction organization and construction simulation respectively in the design, precast component production and construction and installation stages, expanding the application scope of BIM technology in prefabricated building and providing technical support for further integration of prefabricated building and BIM.
