Abstract: In order to reduce the rate of safety accidents and improve the level of safety management, the integrated technology of BIM and RFID sensors were introduced, and from the perspective of danger source management and control, three sources of danger： people, objects and mechanical equipment were identified, and a safety early warning system for construction sites was constructed. Finally, the tomographic analysis method and fuzzy comprehensive evaluation method were used to evaluate the safety management level before and after using the system. The results showed that this system could significantly improve the safety management level of the construction site and provided a new management method for safety management.

Key words: BIM, RFID sensor, construction safety management
