All important dates as they stand after corrigenda: publication, pre-bid/clarification deadline, bid submission deadline, bid opening, and bid validity period.
Published 04 July 2026; online clarification window closed 08 July 2026. The scheduled online pre-bid meeting was 09 July 2026 at 11:00 IST.
After five date corrigenda, the final portal schedule is bid submission by 09 September 2026 at 15:00 IST (09:30 UTC) and techno-commercial opening on 10 September 2026 at 15:30 IST (10:00 UTC). The latest attached date notice only shows the earlier 10/11 August dates; Corrigenda 4 and 5 were portal-only notices without files.
Six months from the date of opening of the technical bid, after considering extensions. A shorter validity makes the offer liable to rejection.
Tender value or estimated cost, EMD/bid security (amount, acceptable forms, validity), tender document fees, performance security, and key payment terms.
No estimated tender value is disclosed. Tender documents are downloadable free of charge; no tender document fee is stated.
INR 96,000.00. Because the amount is up to INR 1 lakh, it must be paid online through the IOCL e-tender portal; DD, banker's cheque and SWIFT are not accepted for this tender amount. Government organisations/central or state PSUs, IOCL JV/subsidiaries and startups in works tenders are exempt on valid proof; MSEs are not exempt.
Initial Security Deposit is 2.5% of total contract value, due within the time stated in award intimation. Permitted modes are online IMPS/NEFT/RTGS; for amounts of at least INR 1 lakh, prescribed BG or ISB. BG/ISB must remain valid three months beyond the defect-liability period. Security is refundable after DLP against final completion certificate.
Lump-sum turnkey price; total payment is capped at the quoted lump sum. Material supply may not exceed 65% of SP-0 and excess is paid only in the final bill; design engineering may not exceed 10% of SP-2 and excess is likewise deferred. No mobilisation advance. Supplies are typically 40% on dispatch, 40% at site in good condition, 10% mechanical completion, 5% commissioning and 5% final completion; electrical services are 45% installation, 35% testing, 10% mechanical completion, 5% commissioning and 5% final bill.
Primary DLP is 12 months from commissioning or 8,000 running hours, whichever is earlier; if commissioning is delayed solely by IOCL beyond 12 months from mechanical completion, DLP becomes 18 months from mechanical completion. Repaired/replaced items carry a fresh 12-month DLP.
Every pass/fail eligibility and qualification requirement: experience and past performance, turnover/net worth, registrations and certifications, consortium/JV rules, and debarment or blacklisting conditions.
Minimum annual turnover INR 2,30,36,000.00 in any one of the three preceding financial years, evidenced by audited financial statements/acceptable CA certification with UDIN as applicable.
During the seven years ending on the last day of the month before the original bid due date: three completed similar works each at least INR 1,15,18,000.00, or two each at least INR 1,53,57,000.00, or one at least INR 1,91,97,000.00, inclusive of GST/service tax.
Similar work means electrical work including 33 kV or above in process plants/refineries/power plants/substations. Additionally, bidder must have supplied, installed, tested and commissioned 33 kV-or-above GIS panels, or executed modification/retrofitting/extension of 33 kV-or-above GIS switchgear panels.
Experience of the bidding entity only counts. Submit WO/PO with scope/SOR and end-client completion evidence showing executed value, completion date and order reference. Subcontract experience needs owner/end-user/consultant permission evidence and completion certificate. Past JV/consortium credentials count only in proportion to bidder's documented share; self-executed own-plant jobs do not count, subject to the stated affiliate-tax-invoice exception.
Domestic bidding only; foreign bidders and joint/consortium bids are not accepted because the tender does not specifically permit them. Tender is reserved for Class-I local suppliers with minimum 50% local content; lower content is rejection-worthy.
Every domestic bidder must submit PF registration regardless of manpower, independent ESI code or prescribed undertaking, PAN, entity-constitution proof and GSTIN/place of registration. The secondary-injection kit must be sourced through its OEM and the bidder must submit a valid OEM authorisation certificate.
Bids are rejected for IOCL/MoPNG holiday listing, liquidation/receivership/insolvency proceedings, consultant conflict, failure of qualification, forged/fabricated documents, unacceptable conditions or missing EMD/exemption. Country-border bidders must be registered with the competent authority; subcontractors from such countries are similarly restricted.
What is being procured: the work, supplies or services, deliverables and quantities, locations, phases, completion or delivery timelines, applicable standards, and notable exclusions.
Single-point-responsibility design, engineering, surveys, procurement, manufacture, TPI, supply, transport/storage, dismantling, modification, civil/structural work, erection, testing and commissioning for re-orienting Barauni Refinery's 33 kV power-evacuation network and developing grid-isolation/islanding with TPS.
Transfer ICT-1 and ICT-2 grid power from 33 kV GIS Board-1 to newly commissioned Board-2; implement virtual-incomer/partial-differential schemes over 8 bus sections of Boards 1-2 and LBB/circuit-breaker-failure schemes over 12 sections/77 feeders of Boards 1-3.
IOCL free-issues the 33 kV HT power cable; contractor handles receipt, storage, laying, termination kits/accessories, 84 indicative termination/reconnection points, testing and commissioning. Contractor supplies about 5,000 m control/signal/OFC cable and installs two three-phase 33 kV/110 V line PT feeder sets at Board-2 panels 13 and 23. Quantities are indicative and may vary ±30%, with all completion quantities included in lump sum.
Retained work includes possible modification of four Board-2 breaker cable-termination arrangements (panels 16, 20, 13, 23), subject to detailed engineering/OEM approval. The separate conversion of panels 16, 17, 20 and 21 from single to double disconnectors is deleted in full; the broad hook-up integration clause and partial-discharge test are also deleted.
Supply one secondary-injection test set with accessories, licensed software, cables, calibration certificate, manuals and case; demonstrate, train IOCL personnel and hand it over after completion. Contractor bears liaison, NOCs/approvals and stage clearances from BSPTCL, CEI Bihar, CEA and other authorities.
Overall completion is eight months from site handover. Installation/commissioning depends on a maximum two-month refinery shutdown execution period, potentially split into up to six visits; IOCL gives at least 15 days' start notice.
Cabling must conform to relevant OISD standards; 33 kV line PTs must meet latest applicable IS/IEC standards and project approvals/testing requirements.
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.
Submit only through https://iocletenders.nic.in under the two-bid system: Part-I techno-commercial and Part-II price BOQ. Complete submission requires clicking FREEZE BID SUBMISSION and receiving/confirming acknowledgement; physical bids are not accepted except specifically required originals.
Bidder registration and submission require a legally valid DSC; new mappings accept Class-3 only. Bids and all scanned documents must be digitally signed by the legally authorised signatory.
For this INR 96,000 EMD, payment is online, so no BG/ISB original applies. If IOCL nevertheless accepts an applicable offline BG/ISB instrument under a changed condition, upload its scan and deliver the sealed original marked ‘Offline EMD’ to the tender issuing authority within seven working days from technical-bid opening; postal delay risk is bidder's.
Use entity-specific authority evidence; POA copies must be Gazetted Officer/Notary certified where applicable. Keep all prices/conditions out of Part-I and upload the unmodified original BOQ workbook in Part-II.
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.
Original submission/opening 18/20 July 2026; Corrigendum 1 moved these to 25/27 July. The 23 July attachment is for unrelated tender 9020C26B98 and was expressly nullified by Corrigendum 3, which moved this tender to 10/11 August. Portal-only Corrigenda 4 and 5 then produced the final 09 September 2026 15:00 IST submission and 10 September 2026 15:30 IST opening. Bidder action: use only the final portal schedule.
Shutdown execution remains capped at two months but may require up to six separate visits depending on fronts/schedule; IOCL gives at least 15 days' start notice. Bidder action: price repeated mobilisation and maintain readiness.
Deleted: partial-discharge test; complete single-to-double-disconnector conversion on Board-2 panels 16/17/20/21; and broad hook-up integration across electrical/instrumentation/communication/safety/security/civil/OWS/drains. Bidder action: remove these from base scope and price, while retaining tender-specific enabling work and GIS cable-termination modifications.
Original requirement that bidder itself be OEM/authorised dealer was replaced: bidder may be any otherwise-qualified entity but must source the secondary-injection kit through the OEM and submit that OEM's valid authorisation. Bidder action: secure tender-specific OEM authorisation.
IOCL rejected requests for 10-month completion, 72% material weightage and ±5% quantity tolerance; retained 8 months, 65% material cap and ±30% indicative variation. Cable GTP comes only during detailed engineering; route/space/enabling quantities remain bidder site-survey risk. Bidder action: price to unchanged tender terms and document survey assumptions.
Final submission/opening: 09 September 2026 15:00 IST / 10 September 2026 15:30 IST; completion 8 months from site handover; shutdown window up to 2 months and 6 visits; EMD INR 96,000 online; disconnector conversion, PD test and broad hook-up clause deleted; secondary-kit OEM authorisation mandatory. All other tender terms remain unchanged.
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.
Form of Tender and checklist state four months, but NIT clause xxxvi states six months after technical-bid opening. NIT expressly supersedes all tender sections, so six months prevails.
Price-bid Form of Tender says sign the formal contract within 10 days of LOA, while later NIT clause lix requires the successful bidder to sign within 30 days of approved Work Order where contract value including GST exceeds INR 50 lakh. NIT prevails; use 30 days where clause lix applies.
GCC sets INR 5,000 per violation plus 1% of lump-sum price (max INR 2 lakh) per injury and 2% (max INR 20 lakh) per fatality. SCC sets INR 5,000 plus 0.5% of contract value (same INR 2 lakh cap) per injury and 1% (max INR 10 lakh) per fatality. The tender does not clearly resolve this GCC/SCC conflict; bidder should seek written confirmation and conservatively price the higher GCC exposure.
The attachment labelled as this tender's second date corrigendum actually names tender 9020C26B98 and a MUWH retrofit job, not 9020C26C15. Corrigendum 3 expressly makes the 23 July due-date corrigendum null and void, so it has no effect on this tender.
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.
Request IOCL to issue/downloadable confirmation of the Corrigenda 4-5 final submission/opening timestamps because the supplied folder has no attachments for them and the latest attached date corrigendum still shows 10/11 August. This is a bid-timeliness risk.
Seek the 33 kV free-issue cable GTP (conductor material, OD, bending radius), source/destination route lengths and available drum lengths before price freeze. IOCL says GTP only at detailed engineering and directs bidders to survey, while all enabling work/joints remain contractor scope.
Confirm whether panels 13 and 23 have verified internal space/clearance for line PTs; if not, specify approved indoor/outdoor fallback location, structure, interface and whether ICT secondary is cable or bushing. IOCL did not answer those technical particulars and left them to tender terms/site survey.
Ask IOCL to confirm whether GCC or SCC injury/fatality deduction percentages and caps apply, because the financial exposure differs by up to INR 10 lakh per fatality.
Confirm that ±30% applies item-wise only within the defined retained scope, and define treatment of cumulative variation or newly discovered scope. Current clauses require all extra completion quantities at no additional price and the pre-bid request to reduce tolerance was rejected.
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.
The contractor owes a complete operable package even for unlisted supplies/services; quantities are indicative and may vary ±30%, with no extra financial implication. This is the principal pricing/contingency risk.
Execution may be split into up to six shutdown visits inside a two-month shutdown period, with only 15 days' mobilisation notice. Delayed fronts or repeated remobilisation can materially affect labour, OEM and equipment costs.
GCC price discount escalates from 1/8% for week one to a 5% cap by week 13; IOCL may also recover actual direct damage. Extension of time is the contractor's sole remedy, with no extended-stay compensation, and ordinary weather, strikes, vendor delays or commercial hardship do not justify EOT.
No mobilisation advance; 65% material and 10% design-engineering caps defer any excess to final bill. Design milestone advances require equivalent ABG valid three months beyond contractual completion; 5% remains to final completion across major payment streams.
Critical cable GTP and exact routes are deferred to detailed engineering/site survey, but receipt, preservation, joints, enabling works and successful completion remain contractor responsibility. Incorrect assumptions can create unpriced termination/civil work.
Contractor bears all liaison, NOCs and statutory approvals without extra payment, and must cure FEED discrepancies/engineering omissions and provide resulting material without extra cost or time. This places substantial interface and design liability on bidder.
Safety deductions range up to the higher GCC figure of 2%/INR 20 lakh per fatality plus INR 5,000; forged PQC documents can trigger rejection, EMD forfeiture, termination and holiday listing. Claims omitted from the final bill are waived.
For contracts above INR 10 crore landed value, CA/cost-accountant local-content certification is required; if category falls, IOCL may impose up to 10% penalty and hold the last 10% until certification.
