A steel structure replacement parts request checklist for EPC sites helps project teams turn site shortages and damage reports into controlled replacement actions. A replacement request should not be a vague email asking for "missing steel parts." It should identify the item, prove the need, define the specification, and track delivery until closeout.
This checklist is written for EPC site teams, project buyers, logistics coordinators, and quality inspectors managing exported steel structure projects. It focuses on replacement control after delivery rather than spare-parts sales.
1. Confirm why replacement is needed
Before requesting replacement parts, the team should confirm whether the item is missing, damaged, incorrectly supplied, locally lost, or only misplaced on site. This prevents duplicate requests and unnecessary shipments.
- Missing item confirmed after package, bolt box, and laydown area checks.
- Damaged item confirmed with report number and photo evidence.
- Wrong specification confirmed against drawing, bolt list, or packing list.
- Document or label problem confirmed by the site receiving team.
- Installation impact confirmed by the site engineer or erection team.
For initial evidence, use the missing parts report checklist and damage report checklist.
2. Identify the replacement item precisely
The supplier or project buyer needs enough detail to remake, select, or ship the correct item. The request should be tied to drawings, marks, specifications, and the affected installation area.
| Item type | Required information |
|---|---|
| Main steel member | Component mark, drawing number, revision, profile, quantity, coating, and installation area. |
| Connection plate | Plate mark, thickness, hole pattern, steel grade, coating, and connected member. |
| Bolts, nuts, washers | Grade, diameter, length, thread, coating, quantity, bolt list reference, and box number. |
| Anchor bolt set | Size, thread length, template mark, nut and washer set, foundation location, and quantity. |
| Labels or documents | Mark list, packing list, certificate, drawing page, or installation reference to replace. |
3. Attach evidence to the request
A replacement request should include enough evidence for quick approval. The goal is to avoid multiple rounds of clarification while site installation is waiting.
- Original report number: missing parts report, damage report, bolt issue report, or site discrepancy report.
- Photos of package labels, component marks, damage, shortage, or incorrect item.
- Packing list, bolt list, mark list, or drawing reference.
- Quantity received, quantity required, and replacement quantity.
- Site impact: affected area, erection sequence, and required delivery date.
For photo evidence, use the delivery photo checklist.
4. Decide whether local purchase is allowed
Some standard accessories may be purchased locally, but only with proper specification control. Main members, special plates, high-strength bolts, coated items, or certified items usually require more careful approval.
| Replacement route | When it may apply |
|---|---|
| Supplier replacement | Custom steel members, special plates, marked items, certified material, or coated components. |
| Local purchase | Standard bolts, washers, or consumables when grade, coating, and certificate requirements are clear. |
| Document resend | Missing certificates, mark lists, packing lists, or drawing pages. |
| Engineering substitution | Only when design or quality approval confirms the substitute is acceptable. |
If the issue is bolt-related, connect the request to the bolt issue report checklist.
5. Define approval responsibility
Replacement requests can affect cost, schedule, quality, and installation sequence. The request should identify who approves the action and who owns follow-up.
- Site engineer confirms installation impact and urgency.
- Quality inspector confirms damage, wrong specification, or acceptance condition.
- Project buyer confirms supplier or local purchase route.
- Engineering team approves substitutions, modifications, or revised details.
- Logistics coordinator confirms shipment method and expected arrival date.
6. Control replacement shipment details
Replacement items often travel separately from the main shipment. The request should make the package easy to identify when it arrives at site.
- Replacement request number printed on package label.
- Project name, destination, site contact, and affected area.
- Component mark or bolt box reference on the package.
- Packing list showing replacement quantity and reason.
- Courier, air freight, sea freight, or local delivery tracking record.
- Photos before dispatch and after site receiving.
For receiving replacement packages, follow the site receiving checklist.
7. Keep a replacement request log
A replacement log helps EPC teams avoid duplicated requests and forgotten closeout items. It also shows which site issues are still blocking installation.
| Log field | Why it matters |
|---|---|
| Request number | Connects the replacement to photos, reports, shipment, and closeout records. |
| Item description | Prevents confusion between similar members, plates, bolts, and labels. |
| Root report | Links the request to missing, damage, bolt, or discrepancy evidence. |
| Owner and due date | Keeps supplier, buyer, and site follow-up visible. |
| Status | Tracks requested, approved, shipped, received, installed, or closed. |
8. Close the request after site confirmation
The request should remain open until the replacement item is received, checked, and accepted for the intended use. Closing the request at dispatch can leave the site with unresolved installation problems.
- Replacement item received at site and matched to the request.
- Quantity, mark, grade, coating, and document checks completed.
- Installation area or affected connection released by the site team.
- Photos and receiving records attached to the request log.
- Final closeout date and responsible person recorded.
For site handover, include the final request in the installation package checklist.
Red flags in replacement parts requests
- The request does not include a component mark, bolt size, drawing number, or package reference.
- Replacement is requested before site sorting and package checks are completed.
- Local purchase is used without grade, coating, certificate, or engineering approval.
- Shipment is arranged without clear package labeling for the site team.
- Request status is closed when shipped, not when received and accepted.
- Replacement items are not linked back to the original missing or damage report.
Buyer note
Replacement parts requests should be specific, evidence-based, and closed only after site confirmation. EPC buyers should use one request number to connect the original issue, replacement specification, approval, shipment record, receiving evidence, and final installation release.
