As a technology with widely recognized value, BIM is becoming more and more mature in the design and construction stage, but it is still in its infancy in the operation and maintenance management stage. The compatibility between big data generated by BIM and asset management systems still needs further research and development especially. Based on the BIM data of the China Southern Airlines building, this paper discusses its compatibility and application with ARCHIBUS and IBMS system. With BIM+FM as the core technical route, it also studies the practices of financial analysis, lease management, asset management, station management, and space management in the actual project.
