Abstract：At present, the application risk of BIM technology in assembly projects, especially how to improve the objectivity of BIM application risk assessment, helps decision makers to carry out BIM application risk management and control has become a hot issue for scholars. In this paper, the Interpretative Structural Model (ISM) is used to cluster and analyze the main risks of BIM technology application in the assembly project and establish a risk index system. Using the improved analytic hierarchy process, the weight of the index is determined by the fuzzy consistent matrix, and the gray system is used. The theory determines the gray and gray evaluation weight vector, and takes the Nanjing International Expo Center project as an example to establish a BIM application risk assessment model to determine the project BIM application risk level. The main conclusion is that BIM technology has a medium application risk in the Nanjing International Expo Center project. The technical and personnel aspects have the greatest impact on the application of BIM in the assembly project. This study provides a new perspective and method for the application risk assessment of BIM technology in assembly projects.
