The operation and maintenance management of college assets is the most effective way to realize the scientific allocation of campus space and the efficient use of campus facilities, which is also an important part of building a "smart campus" at the same time. With the help of BIM technology, this paper realizes the integration and fusion of multi-source campus asset data. A framework system of intelligent campus assets operation and maintenance management platform is constructed, and the related applications of university assets operation and maintenance management platform in campus space, facilities, security and other aspects are expounded. At last, this paper summarizes the advantages and disadvantages of BIM technology in university assets operation and maintenance management, which provides reference for asset operation and maintenance management in related fields.
