As the urban construction is developing rapidly, the development and utilization of urban underground space has become an important development direction. The combined BIM and VR Technology can be applied in the urban underground engineering. A quality model templates is firstly drawn in virtual environment by using Revit, a BIM software. Then the 3DS MAX software is applied for the lighting, material rendering and animation. The exported animation video in avi format achieves immersive dynamic roaming by using the storm mirror, a VR software. The above technical route solves the construction safety and quality problems caused by the limited construction space and complicated pipelines.

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.
