Introduction  At present, the traditional power infrastructure operation and maintenance management system has a low degree of refinement and visualization.In order to improve the quality and efficiency of operation and maintenance management,

  Method  this paper studied and proposed a power infrastructure operation and maintenance management method based on Building Information Modeling (BIM) visualization and information technology.In order to realize the operation and maintenance management method, the existing system architecture was flattened, and the BIM model was defined as the core data carrier.The peripheral system with an independent database could directly extract BIM data or display the BIM model.

  Result  The actual project shows that using BIM visualization and information technology to effectively improve the level of infrastructure operation and maintenance management.

  Conclusion  The proposed BIM-based power infrastructure operation and maintenance management system can be further used in actual projects.
