What is being procured: the work, supplies or services, deliverables and quantities, locations, phases, completion or delivery timelines, applicable standards, and notable exclusions.
Rate Contract for supply of Full Wave Three Phase Silicon Diode Bridge Power Rectifier designed for natural cooling to BHEL Spec PS407613 R00 (material code BP9048118280) for KMMC / ICF SPIC application.
Enquiry quantity is 35 Nos (tentative); supplies are against Purchase Orders issued from time to time during the 18-month RC period; PO may not cover all items and depends on customer PO.
Door delivery FOR CRX, BHEL Bhopal; inspection condition is at BHEL Bhopal; packing must avoid transit damage; gate pass required.
Natural-cooled onboard rectifier per ICF/MD/SPIC-349 R01 cl. 3.11 & Annexure-3; preferably three parallel bridges with N-1 full-duty capability; diode PIV ≥3000 V; IS:7788; power loss ≤1500 W; noise ≤75 dB at 1 m; outline per BHEL drawing 26670600425.
Within 15 days of PO: GA drawing, BOM, wiring drawing, routine & type test schedule, QAP, routine & type test reports; two copies of TC and GC with supply; commissioning support for 1st rectifier on KMMC; O&M where applicable.
Equipment warranty 30 months from supply/receipt at BHEL Bhopal covering free replacement, on-site replacement, troubleshooting and rectification.
The complete checklist of documents to submit — mandatory vs conditional, with any prescribed formats, proformas or annexures — plus how to submit: portal and mode, envelope/cover structure, digital signature requirements, signing and attestation rules, and physical originals with their deadline.
Offers are to be submitted through BHEL e-procurement portal https://eprocurebhel.co.in/nicgep/app; GTC states offers in any other mode will not be accepted for e-procurement enquiries.
Commercial Annexure-II and GTC must be duly filled, signed and sealed; each page of Annexure-II to be signed with seal; MII format filled & signed by authorized signatory on letterhead.
No separate physical-original bid-submission deadline is prescribed for this e-procurement enquiry; post-award tax invoices above ₹5 lakh must be Class-3 DSC signed on the portal (hard copy mandatory if not).
Every corrigendum/addendum in order — what changed (original vs amended value), its impact, and the action for the bidder — ending with the values that finally apply.
Corrigendum 1 is a Date-type amendment whose only attached PDF states that approval was obtained from competent authority; it does not print revised due date, opening date or any other numeric change.
A second Date-type corrigendum is recorded against the tender after Corrigendum 1, but no attachment is present in the document pack, so no original-vs-amended values can be quoted from a corrigendum PDF.
Commercial/technical conditions in the base documents are unchanged by the available corrigendum text; only the bid schedule was targeted by Date corrigenda, and the revised numeric schedule is not printed in the pack.
Genuine conflicts within and across the documents (original vs corrigenda, clause vs annexure, tender document vs BOQ): both sides with citations, and which value prevails.
GTC default warranty is 12 months from receipt, while commercial T&C and PS407613 require 30 months; the enquiry-specific 30-month warranty prevails over GTC under the stated precedence (STC/ATC and technical specs over GTC).
PS407613 starts the 30-month warranty from date of supply at BHEL Bhopal, while commercial T&C starts free-replacement warranty from date of receipt of materials at BHEL Bhopal.
Embedded ICF Annexure-3 states diodes of the main rectifier shall be guaranteed for five years from commissioning, while BHEL PS407613/commercial T&C state 30-month equipment warranty from supply/receipt at Bhopal.
Enquiry line shows delivery date 30/10/26, but remarks say delivery date is indicative for an 18-month RC, and commercial T&C requires delivery within 90 days of each PO or later project need.
GTC provides e-procurement (other modes not accepted), conventional tender-room sealed covers, and limited email submission paths; this tender’s NIC BOQ and e-procure listing make e-procurement the operative mode.
Only critical, tender-specific pre-bid queries that could materially change bid/no-bid, pricing, eligibility or contractual risk. Skip generic or obvious questions the documents already answer clearly.
Ask BHEL/portal admin to confirm the live bid-submission end and opening times because Corrigendum 1 PDF has no dates and Corrigendum 2 has no file, while the enquiry copy still prints 18/08/26.
Seek written clarification whether Annexure-3’s five-year diode guarantee from commissioning is a contractual obligation on top of the 30-month free-replacement warranty, including on-site remedies and start date (commissioning vs receipt).
Confirm whether prior supply of natural-cooled full-wave 3-ph silicon diode bridge rectifiers for closely related rolling-stock platforms other than the named ACSPIC/DETC/KMMC strings will be accepted, and whether private-sector end-user POs without railway rolling-stock linkage qualify.
Commercial T&C does not call a PBG amount; request confirmation that no performance security is required at RC award or on individual POs, and if later demanded, the % and validity basis (warranty end).
Clarify expected call-off profile over 18 months, whether BHEL may place nil POs if customer orders fail, and how GTC ± option (decrease at placement / +25% during currency) applies to the RC quantity of 35.
Confirm where the 1st KMMC rectifier will be commissioned, duration of free support, travel/boarding responsibility, and whether related costs must be built into the unit rate (FOR Bhopal supply price).
Commercial, legal and execution risks a bidder should weigh: liquidated damages and penalties, unusual or one-sided clauses, tight timelines, and payment or security risks.
Unconditional penalty 0.5% of undelivered portion per week (or part) subject to max 10% of undelivered order value, item-wise on PO; GST on recovery also recoverable.
Quoted prices remain firm through offer validity and complete execution of all orders under the 18-month RC with no escalation—cost inflation and commodity risk sit with the bidder.
Qty is tentative; POs only after customer PO; BHEL need not order all items; GTC allows decrease at placement, +25% increase during currency, and cancel/hold/short-close if customer order is cancelled/held/modified; BHEL may negotiate L1 or re-float if price unacceptable.
On breach, BHEL may recover 10% of contract value as pre-estimated damages via encashment of securities/bills/other units’ dues and pursue legal recovery; plus LD, debarment, termination, de-scoping, short-closure; defaulting vendor barred from balance-work enquiries.
30-month free replacement/on-site troubleshooting from Bhopal receipt/supply, possible additional 5-year diode guarantee from commissioning per ICF Annexure-3, plus mandatory support at first KMMC commissioning—long tail liability versus 90-day payment.
Design must meet N-1 full tractive duty, ≤1500 W loss, ≤75 dB noise, PIV ≥3000 V, IS:7788, outline drawing 26670600425 and full Annexure-3 construction/tests (including type tests possibly before RDSO)—non-compliance risks rejection at BHEL Bhopal inspection.
Standard payment is only after receipt and acceptance at BHEL (up to 90 days; faster only for proven MSE/Medium with UDYAM); rejected goods rules allow termination/breach remedies; packing without PO No./material code may cause store rejection.
RA will be run (H-1 usually excluded); deviations may be loaded or offer rejected; single-bid against two-part normally rejected unless already acceptable without clarifications.
With two Date corrigenda and no printable final due time in the pack, missing the live portal deadline is a pure pass/fail risk—especially if working off the enquiry copy’s 18/08/26 date.
The inviting authority and relevant contacts: office, person, designation, address, phone and email — and which address receives physical submissions, if any.
