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.
