In recent years, more and more real estate development companies have realized the value and advantages of BIM technology in project management. But the BIM requirements of most projects are only based on individual technical cases, not integrated into the project management process. This paper takes the A1 tower of the Poly Yuzhu Project as an example, introduces a practice on owner / developer supervised BIM project management, and introduces its implementation benefits of quality management, schedule management, safety management, cost management and coordination management. The analysis and thinking of BIM project management in this mode can be used as a reference for BIM implementation of similar projects.
