Handover connects completed repair work with future asset management. The owner needs to know what was investigated, removed and installed, which checks were carried out, which deviations were accepted and what to watch for later. A neat finish alone does not show that the repair meets every project requirement. [1, 2]

What belongs in the handover record?

Include updated drawings or a damage map; before, during and after photographs; repair boundaries; materials and batches; site and environmental records; inspection and test results; deviations and approvals; product documents; warranties where agreed in the contract; and relevant maintenance instructions. Record who is responsible for open items and when they will be resolved.

Handover record showing a repair map, photographs, test log and next inspection tied to the same concrete element. 1. Element identifier. 2. Repair record. 3. Inspection and tests. 4. Follow-up maintenance.

How should the work be assessed?

Use the acceptance criteria and inspection points agreed in advance. Check that the right areas were repaired, visible finish and interfaces match the plan, and required tests were completed. A test result applies only to its method and location; record its limits. Distinguish a visual review from evidence of bond, filling or structural performance. Have deviations assessed by the designated designer or inspector.

Plan maintenance after repair

Update the asset register with location, date, cause, measure, results and remaining concerns. Set follow-up inspection based on exposure, structural importance, damage history, observed rate of change and the owner’s management system. There is no single interval for every repair. ISO 16311-1 sets general principles for managing and maintaining existing concrete structures; its public abstract does not prescribe a project-specific interval. [1]

Ask which signs should be reported, who will carry out the first inspection, which measurements should be repeated and how they will be compared with the baseline.
