The problems, i.e. unclear requirements and architecture, are often encountered when applicating BIM technology to the entire life cycle of rail transit. First, some application misunderstandings and problems of BIM existed in the Phase 1 project of Beijing Metro Line No. 19 are discussed from the perspective of enterprise management. And then some BIM application concepts in design, construction, operation and maintenance stages are summarized, and current BIM application results in each stage are sorted out. Finally, the development of BIM application in the next stage is considered and summarized. It can be concluded that: (1) At present, we should put into research in advance and do our best in light of the actual situation. (2) At this stage, we mainly promote BIMassisted design and informatized construction of engineering projects with schedule management as the core, to lay a good foundation for asset transfer and operation and maintenance management. (3) Meanwhile, the construction of one datebase and multiple platforms will help to promote the implementation of BIM technology.
