A Steel Fabrication Prequalification Checklist for Procurement Teams
A Steel Fabrication Prequalification Checklist for Procurement Teams
Selecting a steel fabricator is not a comparison of capacity numbers alone. Procurement teams need confidence that the supplier can execute the exact scope, document the required controls and deliver safely to the project timeline.
This checklist is designed for early vendor evaluation. It should be adapted to the technical specification, tender conditions and inspection requirements of the individual package.
1. Confirm the Legal Entity and Contact Route
Start with the basics: registered address, responsible contact, applicable registrations and a clear route for technical or commercial clarification. This reduces avoidable delays when buyer, consultant and inspection teams need records later in the process.
2. Check Product-Specific Approvals
For railway and bridge work, approval must match the actual scope. Do not stop at a generic approved-vendor label. Confirm the current approval, its item scope, the facility it covers and any tender-specific conditions.
Kothari's RDSO capability page identifies its listed approval scope for composite and other steel plate girders, together with registration and validity information. Buyers should still verify current tender requirements before award.
3. Review Capacity in Context
Annual capacity is useful, but it is only one signal. Also examine:
- Shop area, bay layout and staging space
- Handling capacity for the length and weight of the proposed members
- Cutting, drilling, welding and straightening equipment relevant to the package
- Surface-treatment and dispatch readiness when included in scope
- Current production schedule and realistic delivery slots
Kothari's infrastructure page provides a detailed reference for its units, cranes, machinery and listed testing resources.
4. Ask for Quality Evidence Early
The project quality plan should be agreed before fabrication starts. Depending on the package, ask for the relevant approval records, ISO certificate, material traceability approach, inspection plan, welder qualifications and testing arrangements.
The important question is not whether a vendor has every possible document in a brochure. It is whether the vendor can produce the evidence required by your specification at the required stage of work.
5. Review Comparable Project Work
Ask for references that resemble the current package in product type, scale and delivery conditions. A useful case study identifies the client, location, scope and quantity, rather than showing only a project photograph.
Kothari's project case studies present selected bridge and girder work using that format. For full technical due diligence, request the project-specific references and documents appropriate to the tender.
6. Define the Delivery Boundary
Clarify whether the supplier's responsibility includes design review, procurement, fabrication, blasting or coating, inspection, packing, loading and delivery to site. These boundaries have a material effect on cost, programme and handover records.
A Practical Vendor-Pack Request
A concise initial request can ask for:
- Company profile and registered-contact details
- Product-specific approvals and current certificates
- Unit, equipment and handling-capacity information
- Quality and inspection overview
- Comparable completed-project references
- Proposed delivery scope, exclusions and dispatch assumptions
You can begin with the Kothari capability & prequalification profile, then contact the engineering team for package-specific documentation.
