This guide helps a contractor turn a live UP authority tender into a Kanpur pipe RFQ. Copy every material, class, coating, inspection and document requirement; obtain supplier-letter scope, availability, freight, taxes, dates and validity in a current written response.
The supplier-side of a UP PWD steel-pipe tender is not where the material schedule; the document matrix matters equally. Map each manufacturer, licence-scope, marking, test, traceability, inspection, invoice, transport and supplier-letter requirement to its issuer and review point. This page is a practical reference for contractors and procurement teams running an active bid.
What a UP PWD pipe tender is asking the supplier to be
A UP PWD or Jal Nigam pipe tender is a contractor bid on an e-procurement portal, not a mill empanelment. The pipe supplier may sit behind the contractor only where the tender permits and defines that role. Copy the governing product standard, edition, dimensional scope, class and evidence from each BOQ line; do not assign IS 1239, IS 3589 or Heavy Class from an NB or service label alone. This is not IBR boiler-tube work, and it is not a retail plumbing counter sale.
The PWD tender categories that move steel pipe in UP
The four labels below are navigation aids, not claims about demand, material defaults or evaluation practice. Each live package has its own authority, technical specification, amendments and evaluation conditions.
UP Jal Nigam
Water, distribution and sewerage packages. Copy the exact pipe standard, edition, class, coating, dimensions, marking, inspection and acceptance criteria from the issued tender and amendments; the authority package has no universal material default.
CPWD / State PWD
Building-services packages can cover water, hydrants, risers and sanitary work. Use the approved service schedule and design for each material and class. A cited CPWD specification may name Heavy Class within its scope, but NBC does not create a universal class rule.
UPSIDC / Industrial Areas
Industrial-area water, fire, effluent or fuel services may use different product standards. Copy every material line from the authority-approved tender and design instead of inferring a mix from the industry label.
NHAI sub-tier
Highway sub-tier packages may include drainage, lighting, water or fire scope. The EPC contract, drawings, named standards and acceptance plan control; this page does not claim work for particular contractors.
Documentation a PWD tender requires
Six core documents land in the technical bid envelope. The evaluation committee checks each one against a published qualification checklist; a missing or expired document is a technical disqualification regardless of bid price.
- Valid BIS licence number. Mill-side BIS licence for the IS spec being supplied. Cite on the MTC and on the supplier-of-record letter.
- Product marking. Copy the exact physical-marking requirement from the purchased standard and tender; verify it at the named inspection point.
- Test and traceability records. State the chemistry, mechanical, dimensional and traceability evidence required by the tender and inspection plan.
- Registration records. Provide only the tax, Udyam or other registration evidence explicitly required by the live tender.
- Financial qualification. Copy the required periods, form, signatory and thresholds from the live tender rather than assuming three years.
- EMD and performance security. Use only the amount, form, timing, validity, release and forfeiture terms in the live tender and award documents.
Who this Kanpur path suits, and who should look elsewhere
This path suits contractors bidding Jal Nigam distribution, CPWD or state PWD building services, UPSIDC industrial-area mains, and NHAI sub-tier water and fire networks in Uttar Pradesh. It also suits JJM contractors whose village distribution still calls IS 1239 GI; the official Jal Jeevan Mission scope. Fire-system material and class require the approved hydraulic design and authority-cleared schedule; do not apply a generic pressure band or Heavy-Class default.
Look elsewhere for IBR boiler tubes, for HDPE trunk mains, and for a single-length retail buy. Do not substitute any class against the approved BOQ. Do not treat a Kanpur stockist letter as a PWD empanelment: empanelment is contractor-side. Sugar-mill retubing belongs on the sugar mill boiler tube page; village GI tranches on the JJM contractor page.
IS 1239 class table for a 50 NB tender line
Walls and masses below are the IS 1239 50 NB (OD 60.3 mm) figures from our pipe-weight data. The GI bands were recorded on 24 May 2026 and are historical comparison context only, not current rates, stock or a tax rule. Confirm all test and acceptance requirements from the purchased standard edition.
| Class | Wall at 50 NB (mm) | Mass (kg/m) | Mass per 6 m (kg) | GI band (Rs/kg) | Typical tender use |
|---|---|---|---|---|---|
| Light (Class A) | 2.9 | 4.10 | 24.6 | 61-69 | Use only where the approved tender and design name Light Class |
| Medium (Class B) | 3.6 | 5.03 | 30.2 | 65-73 | Use only where the approved tender and design name Medium Class |
| Heavy (Class C) | 4.5 | 6.19 | 37.1 | 71-79 | Use only where the approved tender and design name Heavy Class |
Worked example: 100 NB Heavy wet-riser mass
Theoretical carbon-steel mass uses W = (OD minus wall) times wall times 0.02466, with OD and wall in millimetres. 100 NB Heavy class is OD 114.3 mm and wall 5.4 mm, which is 14.50 kg/m or 87.0 kg per 6 m length. A 24 m internal wet-riser (four lengths) therefore weighs 348 kg. At the published GI Heavy 100 NB band of 68 to 76 Rs/kg, the material budgets 23,664 to 26,448 Rs using that dated band. A current quotation must state the offered rate, mass basis, freight, legally applicable taxes and validity. Confirm the wall on the IS 1239 class thickness chart and the arithmetic on the pipe weight chart.
RFQ checklist for a Kanpur tender BOQ
A BOQ with these nine items supports a current technical and commercial review; it does not guarantee a supplier letter or timing.
- NB and class per line. Copy each NB and class from the approved BOQ and drawings; flag unclear services for design clarification.
- Finish. Black MS or GI to IS 4736. Do not write "galvanized" without the IS 4736 callout.
- Length and quantity. State the required or offered length and site-wise split; do not assume a universal mill length.
- Grade / standard. Copy the exact product standard, edition, material and dimensional scope from each BOQ line.
- Test records and BIS. State required traceability, test records, BIS licence-scope evidence and physical marking.
- TPI. Agency name (SGS, Bureau Veritas, Lloyds, or state-empanelled) if the technical spec buries a TPI clause.
- EMD / SD context. State whether a supplier letter is required, its scope, beneficiary, obligations and exact validity.
- Consignee. Provide the authorised particulars required by the tender, PO and current invoice or transport law.
- Delivery basis. Ask the offer to state material location, collection or destination basis, freight, risk transfer, taxes and dates.
The four mistakes that lose PWD pipe contracts
These four checks help prevent specification and documentation gaps. Actual evaluation, receipt and remedies remain controlled by the tender and contract.
Quoting the wrong pipe class
Copy the class named for each line. An unapproved substitution can fail technical evaluation or receipt, but rejection and security consequences depend on the tender and contract.
Sourcing from non-ISI / non-BIS-licensed mills
Where BIS certification is mandatory, verify the proposed manufacturer, manufacturing unit, product and size against the current licence scope and required marking before commitment.
Missing the TPI clause
Read the full inspection clause and name the agency or approval method, location, scope, hold points, fees, records and release authority before the PO. Do not assume an agency or delay.
GST and e-way bill mismatch
Reconcile the authorised consignee and the particulars required by current tax and transport law with the PO. Handle any mismatch through the contract rather than claiming routine rejection.
How RP Sales fits into a PWD pipe tender
Where the live tender permits a supplier letter, use this review sequence:
- Pre-bid: BOQ review and mill confirmation. Contractor shares the technical specification and BOQ. We compare it with the proposed manufacturer, current licence scope and offered records, and flag any clause that may need clarification.
- Bid submission: supplier-of-record letter. Agree in writing whether a supplier letter can be issued and define its bidder, tender, products, quantities, rates, obligations and exact validity.
- Award: PO and document review. Reconcile the PO with the award and define submission, review, inspection and release points before movement.
- Release: contract-specific evidence. Provide only the marking, test, traceability, inspection, invoice and transport records required by the accepted PO and current law.
- Receipt and query handling. Route receipt and documentation questions through the named contract contacts and response process; no response time is promised here.
Buying IS 1239 pipe in Kanpur for a UP tender
Use Kanpur as the proposed enquiry or collection point only when the current written response confirms it. Send the live tender, amendments, BOQ, inspection plan and authorised destination. Require the quotation to state manufacturer, material location, availability, freight, risk transfer, legally applicable taxes, dates and validity. This page makes no corridor or nationwide delivery promise.
Central CPWD bids run on the Government eProcurement System at etenders.gov.in. UP state bids we opened on 3 September 2026 resolve at etender.up.nic.in under the title eProcurement System Government of Uttar Pradesh. Start from GI pipes Kanpur, MS ERW supplier Kanpur, steel pipes Kanpur, steel pipes Lucknow, steel pipes Unnao, fire hydrant spec, GI price list, Kanpur steel market and the RFQ form.
Standards and tender clauses to name on the BOQ
IS 1239 Part 1:2004 covers welded steel tubes 15 to 150 mm NB in Light, Medium and Heavy class, black or galvanized. Verify test and acceptance criteria in the purchased edition. IS 3589 may apply where the tender names it within its product scope; it does not automatically take over at one OD. Galvanizing is specified separately as IS 4736; write the coating spec next to the tube spec rather than the word galvanized alone. NBC 2016 Part 4 (Fire and Life Safety) informs fire design but does not by itself force one pipe class. For boiler work, the Boilers Act, 2025 has been in force since 1 May 2025 and the applicable IBR form is component-specific: III-A for steam pipes, III-B for tubes and III-C for boiler mountings and fittings.
Mill documentation must match the tender: typically the MTC keyed to the heat on the pipe, the mill BIS licence number and any named inspection release. Under EN 10204, Type 3.2 is validated by both the manufacturer's authorised inspection representative independent of the manufacturing department and either the purchaser's authorised representative or an inspector designated under the applicable official rules. A tender that merely asks for third-party inspection should identify the required document and signatories instead of being assumed to require Type 3.2. The live e-procurement sources below are the portal pages used for the procurement references.
Key points
- RP Sales is the supplier-of-record behind the contractor, not a PWD-empanelled mill.
- 50 NB Medium is 3.6 mm wall and 5.03 kg/m; Heavy at the same NB is 4.5 mm and 6.19 kg/m.
- A 24 m run of 100 NB Heavy is 348 kg; GI Heavy 100 NB bands are 68 to 76 Rs/kg ex-Kanpur.
- Fire and wet-riser class comes from the approved design, project specification and authority-cleared schedule.
- Confirm material location, documents, freight, taxes, dates and validity in the current quotation and PO.
