1. Inspection-archiving stage
Images, defects and model data generated by each inspection are uniformly stored and archived, updating the “one bridge, one archive” digital file and providing complete historical evidence for maintenance decisions.
2. Maintenance-re-inspection stage
Maintenance records and repair data continue to merge into the archive; re-inspection data is archived in sync, and defect changes and maintenance effectiveness can be traced across periods, supporting maintenance priority and repair decisions.
3. Continuous archive update mechanism
The archive is continuously updated and iterated with inspection, maintenance and re-inspection, forming the “inspection-archiving-maintenance-re-inspection-archive update” loop, achieving full-lifecycle digital bridge management and turning every operation into long-term assets.
4. Applicable conditions and scenarios
- Key bridges incorporated into routine maintenance mechanisms
- Owner organizations needing maintenance effectiveness evaluation
- Projects pursuing full-lifecycle digital management
5. Notes
Closed-loop management depends on regular inspection and data updates; it is recommended to include it in the annual maintenance plan to keep the archive continuously valid.
