Abstract: With the continuous development of the construction industry, BIM technology is being adopted. However, in practical engineering, there is a large investment decision risk in the deepening promotion of BIM technology, which leads to a certain obstacle to the promotion of BIM technology. This paper determines the risk factors through the problems encountered in the application of BIM technology and the use of literature review method. The Delphi method and social network analysis method are used to identify and to analyze the risks. Finally, it is concluded that during the process of BIM technology application, there are no complete legal provisions and measures, no obvious benefit recovery, and low sustainable utilization rate of achievements.
