Application of BIM Technology in Design Stage of Prefabricated Project of Tencent Large-Scale Double-Venture Community

The EPC contracting projects usually have the characteristics of large volume and long construction period, while the prefabricated buildings challenge the precision of design and the accuracy of project information transmission. As the carrier of building information digitalization, the BIM technology has the characteristics of digitalization of design expression, coordination of data and information, continuity of information transmission, diversification of data functions, and convenience and controllability of information transfer. Taking the Tencent large-scale double-venture community project in Chongqing as an example, the paper explores the application of BIM technology in the early stage scheme determination and design stage of large EPC prefabricated project. According to the needs of EPC project management, the concept of "pre-planning, post-evaluation" was implemented in the process of the project, improving the design quality and achieving the cost control through the application of BIM technology, and the combination of BIM and other new technologies was explored as well. The study lays a solid foundation for the later construction and operation stage of the project, and provides valuable experience for the BIM application in process of design for EPC projects.
