Record the source
Inspector, method, date and asset identity should be traceable.
Use repeatable terminology
Free-text notes are useful, but structured fields help portfolio analysis.
Flag uncertainty
Inaccessible areas or uncertain asset identity should not silently become definitive data.
Review unusual changes
A dramatic score improvement or deterioration may reflect a real event, a changed method or a data error.
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.
