BIM intelligent review is one of the important implementation methods for BIM model review in engineering projects. Due to its convenient, fast, and accurate characteristics, it has become a research hotspot in the construction industry. Therefore, BIM model automatic review systems have been launched in Guangzhou, Nanjing and other cities. However, it is difficult to study BIM intelligent review of municipal project BIM models due to numerous subdivisional work and complex spatial structures. Considering standardization and modularization characteristics of municipal prefabricated structures, this paper studies the key technologies of municipal prefabricated engineering BIM model intelligent review. It proposes that the key technologies of BIM model intelligent review mainly include the establishment of standardized component family libraries, the development of model coding standards, and the automatic inspection of standardized components of BIM models based on the clauses in the BIM Review Guide published by various regions and departments through programming. By utilizing the above key technologies, this paper proposes an intelligent review method for checking integrity of municipal prefabricated structural BIM models and validity of its components' LOD, providing a reference for the intelligent review research of BIM models in other disciplines of municipal engineering.
