A steel structure post repair inspection checklist helps EPC buyers confirm that repaired components are actually ready for release. Repair completion does not automatically mean acceptance. The buyer still needs to verify the repaired area, compare the result with the approved repair method, review inspection records, and decide whether the item can be released, held, or accepted with condition.
This checklist applies after weld repair, coating repair, dimensional correction, packing damage repair, mark correction, site damage repair, or any repair linked to an NCR, quality hold, inspection comment, or delivery discrepancy.
1. Confirm the repaired item identity
Start by confirming the component mark, package number, drawing revision, defect reference, repair record, and inspection report. The inspection file should clearly connect the repaired area to the original NCR or inspection comment. If the repaired item cannot be identified, the release decision is not reliable.
Photos and inspection records should show the same component mark or a traceable package reference. This is especially important for export shipments where the site team may review the evidence weeks after the repair was performed.
2. Compare repair work with the approved method
The post repair inspection should verify that the completed repair matches the approved method. Do not inspect only the final appearance. Check whether the supplier followed the agreed procedure, used the correct materials, maintained required preparation steps, and completed any required intermediate inspections.
| Repair type | Post repair inspection focus |
|---|---|
| Weld repair | WPS reference, repair length, grinding, visual inspection, NDT result if required. |
| Coating repair | Surface preparation, repair material, DFT, curing, final surface, adhesion if required. |
| Dimensional correction | Re-measurement, tolerance comparison, connection fit, drawing revision. |
| Mark correction | Correct mark, label durability, packing list update, photo evidence. |
| Packing damage repair | Protection restored, small parts secured, bundle or crate label confirmed. |
3. Inspect the repaired area directly
The inspector should review the exact repaired area, not a nearby or general component photo. For visual checks, confirm surface condition, cracks, deformation, exposed steel, poor grinding, weld defects, coating holidays, or remaining damage. For dimensional repair, verify measurements after repair, not before repair.
If the repair is covered by paint, insulation, fireproofing, or packing before final inspection, the buyer should request intermediate evidence showing the repair before it became hidden.
4. Review required tests and measurements
Post repair inspection often requires more than visual evidence. Depending on the defect, the buyer may need dimensional checks, NDT reports, coating DFT readings, galvanizing repair thickness, bolt fit verification, or packaging re-check records. The report should state pass, fail, or conditional status.
If the test requirement was defined in the repair method or project quality plan, missing test evidence should block closeout until the record is provided or formally waived by the correct authority.
5. Confirm NCR and quality hold status
If the repair was connected to an NCR or quality hold, the post repair inspection should confirm whether the NCR can be closed and whether the hold can be released. The inspector should not mark the item released if the NCR remains open for missing evidence, pending signatures, or repeated defect review.
For conditional release, record the remaining condition, owner, due date, and evidence required after release.
6. Check final photos and document package
Final photos should show the repaired area after inspection and should be stored with the repair record. The document package may include approved repair method, before and after photos, inspection report, measurement sheet, NDT report, coating record, NCR closeout, and final release note.
Evidence should be named and organized so the site team or owner can retrieve it without searching through unrelated emails.
7. Decide final release status
The inspection result should end with a clear status. Avoid vague wording such as "seems okay" or "supplier confirmed." Use controlled status labels that guide the next step.
| Status | Meaning | Next action |
|---|---|---|
| Released | Repair passed inspection and required records are complete. | Update NCR, quality hold, and release file. |
| Released with condition | Repair is acceptable but a controlled item remains open. | Record owner, due date, and evidence required. |
| Re-inspection required | Evidence is incomplete or result is uncertain. | Hold release until inspection is repeated. |
| Repair rejected | Repair failed or does not match the approved method. | Issue new disposition or corrective action. |
| Transferred to site | Remaining item will be handled at site with approval. | Send site instruction and acceptance record. |
8. Include post repair inspection in handover
When a repaired component is shipped or released to site, the post repair inspection record should be included in the handover package if the issue may be reviewed again. This prevents the site team from reopening a repaired issue due to missing context.
The handover note should identify the component mark, repair reference, final status, and any remaining instruction. If a repair was accepted under concession, link the concession record to the post repair inspection file.
9. Track repair inspection failures
A failed post repair inspection is a supplier performance signal. Track whether repairs fail because of poor method approval, incomplete photos, inadequate workmanship, missing re-inspection, repeated coating damage, or weak document control.
Repeated failures should lead to corrective action, stronger hold points, or tighter release requirements in future batches.
Warning signs
- The repair method was approved, but the completed work does not match it.
- Final photos do not show the actual repaired area or component mark.
- Required NDT, DFT, dimensional, or visual inspection records are missing.
- The NCR is marked closed while quality hold status remains open.
- The item is released by supplier statement without buyer or inspector acceptance.
- Repeated repair failures are not escalated into corrective action.
Buyer note
Post repair inspection is the point where repair work becomes a release decision. The buyer should be able to see the original issue, approved method, completed repair, inspection evidence, closeout status, and final release decision in one traceable package.
