A structural fabricator in Surat had been bidding on NHAI highway project subcontracts for two years. The bids were priced competitively and the fabrication quality was good. The problem surfaced at execution: documentation. When NHAI's TPI agency arrived for pre-dispatch inspection, the fabricator's cert package was invariably incomplete — missing NABL lab reports, MTCs without CM/L numbers, or BIS licences not verified on the portal. Each hold caused days of delay. The project coordinator stopped renewing the subcontract.
The fabricator eventually fixed the documentation problem. Twelve months later, that same NHAI coordinator referred them to two new project owners. The technical quality hadn't changed. The difference was reliable paperwork.
What Government Infrastructure Projects Require
The documentation requirements vary by client, project type, and contract specifications, but the core package for ISI-marked structural steel on government projects typically includes:
1. Mill Test Certificate with BIS elements
- Heat number, grade, dimensions, weight
- Chemical composition and mechanical test results
- BIS licence number (CM/L number) of the producing mill
- Date of issue
2. BIS licence verification
- Printout or screenshot of BIS portal showing the CM/L number as active
- This is increasingly required as a separate document, not just the CM/L number on the MTC
3. NABL-accredited test report
- For NHAI and many CPWD projects: a test report from a NABL-accredited external laboratory, not just the mill's own records
- Must show NABL certificate number and scope
- Tests typically required: tensile (yield strength, UTS, elongation), bend, chemical analysis
4. TPI certificate (where required)
- For large structural steel orders or for projects with explicit TPI clauses in the contract
- Issued by the TPI agency named in the project contract
- Covers the specific consignment, not the mill generally
5. Physical ISI mark on material
- Inspectors verify the ISI mark on plates or rib markings on bars
- For painted or coated material, the mark must be visible before coating or documented in the fabrication record
How Requirements Differ by Project Type
NHAI highway and expressway projects: Typically require NABL test reports for all primary structural steel, ISI-marked material, and TPI inspection by an approved agency (often Bureau Veritas, SGS, or RITES). BIS portal verification of CM/L numbers is standard practice for TPI teams.
CPWD building projects: Require ISI-marked material for structural steel and rebar. MTC completeness checked at site. Some CPWD projects require external NABL test reports; others accept the mill's NABL-certified MTC. Check the project specification, not the general CPWD specification book.
Indian Railways: Procurement for track, bridges, and station infrastructure uses IRS specifications that overlay IS standards. For structural steel, BIS certification requirements align with IS 2062 and IS 808. The Railway Board has issued specific guidelines on MTC requirements that go beyond the IS standard requirements.
Defence projects: Ministry of Defence procurement applies additional quality assurance through the Director General of Quality Assurance (DGQA). Testing and certification requirements can be more stringent. Some defence contracts require witness testing at the mill by DGQA-authorised inspectors alongside BIS certification.
The Order Acceptance Checklist
The most common reason distributors and fabricators lose government project relationships is not quality — it is documentation that arrives at delivery, incomplete. By then, the material is at the project site, the schedule is under pressure, and incomplete paperwork creates holds that the project coordinator has to manage upward.
The fix is moving documentation verification to order acceptance — before procurement, before production.
At order acceptance for a government project:
- Confirm the project specification's exact documentation requirements (not what you assume based on past projects)
- Confirm your supplier holds an active BIS licence for the specific grade and product form
- Confirm an NABL test report will accompany the MTC (and specify which NABL lab will be used)
- Confirm whether a TPI certificate is required and, if so, which agency is named in the contract
- Record all of these as delivery conditions on the purchase order to your supplier
This conversation with the supplier at order time is faster and cheaper than a hold at the project site.
Building a Reusable Government Project Cert Package Template
For distributors and fabricators who regularly supply to government projects, a standard cert package template reduces preparation time and documentation errors.
The template is a checklist and cover sheet that accompanies every consignment:
| Document | Required (Y/N) | Reference | Verification Status |
|---|---|---|---|
| MTC with heat number | Y | Heat: [number] | [ ] |
| CM/L number on MTC | Y | CM/L: [number] | [ ] |
| BIS portal printout (active) | Y | Date checked: [date] | [ ] |
| NABL test report | Y | Lab: [name], NABL no: [number] | [ ] |
| TPI certificate | Per contract | Agency: [name] | [ ] |
| ISI mark confirmed on material | Y | Inspector: [name] | [ ] |
This cover sheet, signed by the quality manager before dispatch, creates an auditable record. When the TPI inspector or project engineer asks for the cert package, it is assembled and ready. When a project coordinator calls to check on documentation status, the answer is immediate.
Distributors who can consistently produce this package at first request — without back-and-forth — build a reputation that carries more weight in government procurement circles than price alone.
