Define the target outcome
The goal may be restoring capacity, slowing deterioration, improving reliability or extending service life.
Understand what remains
A rehabilitation can leave older components, geometry or constraints in place.
Estimate the extension honestly
Added life is uncertain and should reflect condition and intervention scope.
Plan the next decision
A successful rehabilitation still needs future inspection and eventual renewal planning.
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.
