Inspection creates information
Its purpose is to observe, measure or verify condition and performance.
Maintenance changes the baseline
Cleaning, adjustment, repair or replacement can alter the condition that future inspections will see.
Record both events
The asset history should distinguish what was found from what was done.
Coordinate schedules
Inspection just before planned maintenance may help target work, while post-maintenance verification can confirm outcomes.
Scope. This page explains asset-management concepts, not operating procedures for critical infrastructure. Inspection methods, intervention thresholds and safety decisions must follow the asset owner’s standards, local rules and qualified professional judgement.
