Condition & Maintenance

Inspection programs: frequency, scope and evidence

An inspection program links asset type, consequence, deterioration mechanisms and information needs to an appropriate review schedule.

Not every asset needs the same frequency

Inspection intervals can differ with asset role, environment, previous findings, accessibility and governing requirements.

Scope should answer a decision

Inspections are more useful when teams know what decision the evidence is meant to support.

Record limitations

Restricted access, weather, obscured areas and unavailable records should be documented so later users understand uncertainty.

Escalation belongs in owner procedures

Field findings that may affect safety or service require the asset owner’s established escalation process and qualified review.

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.
