Building Information Modeling sets up the building model based on the various relevant information and data of construction projects and simulates the real information of constructions by digital information simulation. The modeling is visualized and coordinated and can be imitated, optimized and plotted. Yong Li International Financial Center Project is a typical super high-rise building with core tube and steel structure inside. Its mechanical and electrical engineering contains chilled water, ventilation, electric, drainage, fire protection and so on, and the traditional method could not meet the detailed design need of the project, thus, BIM technology is adopted to deepen the design in the specialty. In the application of the technology, the team of this project continues to innovate. Bearing the idea of " BIM + " in mind, the team has found many new technologies for construction management, which greatly improves the whole management level. The article mainly introduces the implementation of BIM in this project.
