Taking Tencent Beijing Headquarters project as an example, this article introduces the integrated BIM application in construction from such five aspects as general project situation, BIM organization and application environment, BIM applications, application effect and summery. In addition to using BIM technology in technology management (BIM supporting drawings joint checkup and optimization, and BIM-based deepening design, and construction simulation), quality management (BIM dynamic modeling and non-contact type measurement), security management, and business management (double quantity checkup and change engineering volume management), the project also uses Tsinghua University 4D-BIM system as a platform to further study the BIM-based general contract management, develops a comprehensive management mode of multi-participation and multi-terminal, and realizes the goal of integrated management. In addition, the project also innovatively applies and explores BIM smart layout, three-dimensional laser scanning, 3D printing and other innovative applications, and it can provide reference to other projects with BIM applications.
