Abstract: With the development of intelligence in the construction field, the engineering construction enterprises are gradually transforming into digital ones.The emergence of VR also maximizes the 3D visualization of BIM.Combining the BIM and VR in the construction industry, the existed BIM model libraries are able to convert into VR model libraries in batches, and furtherly the subsystem of BIM and VR for collaboration can be designed.The system solves the problems of online collaborative work of different design units, construction safety and quality control and project progress control.It also enables designers and consumers to experience the existence of buildings through immersive dynamic roaming.The study is of great significance in the field of construction industry.
