All important dates as they stand after corrigenda: publication, pre-bid/clarification deadline, bid submission deadline, bid opening, and bid validity period.
The tender was e-published on 08/07/2026 at 18:00; document download and bid submission opened at the same time, and document download closes on 23/07/2026 at 18:00.
Online clarifications may be sought up to 16/07/2026 at 18:00. No pre-bid meeting is scheduled (NA).
Online bid submission closes on 23/07/2026 at 18:00. If fewer than three bids are received, the portal automatically extends submission, EMD receipt and opening once by four days, ending at 17:00, subject to the next-working-day rule.
Technical Bid (Cover I) opens on 24/07/2026 at 11:30 AM. Price Bid (Cover II) opening will be notified later on the e-procurement portal.
The bid must remain valid for 120 days from the final end date of bid submission; a shorter validity is rejected. WCL may request a written extension, which a bidder may refuse without forfeiting bid security.
Tender value or estimated cost, EMD/bid security (amount, acceptable forms, validity), tender document fees, performance security, and key payment terms.
Estimated cost is Rs. 79,56,629.00, inclusive of GST; input tax credit is not available to WCL.
EMD is Rs. 99,500.00 and must be received online before bid submission, through net-banking from designated banks or NEFT/RTGS from a scheduled bank using the portal challan. This works tender does not receive the services-only MSE exemption. No separate EMD validity is stated; it is governed through bid validity and may be adjusted against performance security at the successful bidder's option.
Security deposit comprises 5% performance security plus 5% retention from running bills, both calculated excluding GST and bearing no interest. Performance security is due within 21 days of LOA, with a possible justified 14-day extension. Acceptable forms are NEFT/RTGS, scheduled-commercial-bank BG (BG applicable when security exceeds Rs. 5.0 lakhs), or pledged Government securities/FDR/other stipulated deposit. A performance BG must remain valid for one year or 90 days beyond the contract/extended contract, whichever is longer.
Because the tensile roof is declared specialized work, security attributable to the specialized items is 10% of their value excluding GST and is refunded only after the five-year guarantee period. It may be released after 12 months against an equivalent BG and the required guarantee; BGs against performance security and retention must extend 90 days beyond the guarantee period.
Running-account payments may be made monthly or at work-order intervals, based on joint measurements and Engineer-in-Charge certification, after deductions including security. Final payment requires final measurements, applicable deductions, a no-claim certificate and proof of royalty payment for minor minerals. Rates are fixed; price variation is not applicable. No mobilization advance is payable because the estimated value is below Rs. 10 crore.
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.
After Corrigendum 1, similar work means construction of tensile fabric structures. Within the seven years ending the last day of the month before publication, the bidder must have successfully completed either three similar works each at least 40% of estimated cost, two each at least 50%, or one at least 80%. Ongoing/incomplete work at the eligibility cut-off is not counted; completed values receive simple 7% annual updating.
Average annual financial turnover during the last three financial years ending 31 March of the previous financial year must be at least 30% of estimated cost. Missing-year turnover is treated as zero; historical turnover receives simple 7% annual updating. Evidence must be a practicing CA's turnover certificate with UDIN and ICAI membership number.
An individual, proprietorship, partnership, company or other eligible legal entity may bid, but must prove legal status, hold a valid PAN, declare an applicable GST status and possess the corresponding GST certificate or CA/UDIN certificate of non-registration, and register on the CIL portal with a CCA-authorized traceable DSC.
Joint venture participation is not applicable because the estimated cost is below Rs. 2 crore. The tender-specific prohibition prevails over generic JV qualification text elsewhere in the template; consortium participation is not separately provided.
The bidder must disclose whether it is debarred, banned or delisted by any Government, quasi-Government agency or PSU; disclose local-content debarment; comply with the Code of Integrity; and certify compliance with land-border procurement restrictions. A bidder from a country sharing a land border with India must hold valid competent-authority registration at bid submission and acceptance. False local-content declarations may cause debarment for up to two years.
The bidder must self-certify local content and its Class-I or Class-II local-supplier status, including the percentage and locations of local value addition. The printed undertaking uses at least 50% for Class-I and more than 20% but less than 50% for Class-II.
What is being procured: the work, supplies or services, deliverables and quantities, locations, phases, completion or delivery timelines, applicable standards, and notable exclusions.
Design and construct a tensile-fabric roofing structure at the entrance of the AGM Office building and its premises under TA, Umrer Area. The contract location is Umrer Area and the completion period is 90 days.
The BOQ includes excavation and reinforced-concrete foundations, holding-down bolts, structural and tubular steel framing, 436.08 sqm of minimum 900 GSM PVC-coated polyester tensile fabric, fixing of the same 436.08 sqm with cables/plates/hardware, and 354.95 sqm epoxy finishing to steelwork. The canopy must resist local peak wind speeds, maintain 10%-15% minimum slope against ponding, and provide at least 3.0 m lowest-point clearance for emergency/VIP vehicles.
Fabric is specified as PVC-coated polyester, minimum 900 GSM, with minimum tensile strength 4000 N/5 cm warp and 3500 N/5 cm weft, minimum tear strength 500 N, NFPA 701/DIN 4102-B1 fire retardancy, minimum five-year outdoor UV resistance, ISO 105-B02 grade 7-8 colour fastness, at least 1500 mm hydrostatic-head waterproofing and PVDF/acrylic-lacquer coating on both sides. Civil works follow the latest CPWD specification conforming to the adopted CIL/Subsidiary DSR/SOR.
The contractor must obtain VNIT vetting of the entire structural design at its own cost before work starts, within 21 days of LOA. The tensile roofing structure carries a five-year guarantee, with security refund governed by the specialized-work clause.
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 online at https://coalindiatenders.nic.in; offline bids are not accepted. Upload confirmatory documents in Cover I/OID and the completed, unmodified Excel BOQ in Cover II. Only one PDF may be uploaded against each eligibility criterion, so supporting pages must be combined into that file.
Portal registration requires a valid CCA-authorized, root-traceable DSC. The bid is digitally signed by the DSC holder and needs no physical signature. If the DSC holder acts for the bidder, upload a power of attorney or other legally acceptable authorization. No physical bid originals are required; post-award, an original performance BG issued by a bank must be sent by the issuing bank to WCL's Civil Engineering Division.
Bid documents must be in English. The online user agreement, Letter of Bid, Annexure II undertaking and other GTE declarations must be accepted unconditionally; conditional bids are not accepted. Deficient confirmatory documents may be requested once online for up to seven days, but no new experience contract may be introduced to qualify.
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.
Issued 11/07/2026, Corrigendum 1 replaces the original Clause 8.A definition. Original: building work involving structural steel and/or structural-steel fabrication and erection including concrete foundations. Amended: construction of tensile fabric structures. Impact/action: only tensile-fabric-structure completion credentials should be relied on for qualification; re-check the 40%/50%/80% thresholds against such contracts.
Original additional condition: NIL. Amended condition: the contractor must have the entire structural design vetted through VNIT at its own cost before starting work and within 21 days of LOA. Impact/action: include VNIT vetting cost and programme in the bid, secure the review slot early, and do not commence site work before vetting.
The final substantive conditions are: similar work = construction of tensile fabric structures; VNIT vetting at bidder/contractor cost before work starts and within 21 days of LOA. Corrigendum 1 does not amend the tender schedule, estimated cost, EMD, 90-day completion period or five-year guarantee, so the NIT values for those items remain applicable.
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.
The NIT requires a five-year tensile-fabric-roofing guarantee using Annexure X, but Annexure X is expressly a waterproofing guarantee and discusses leak-proof treatment, misuse of roof and alterations. Clause 4.9's specialized-work obligation prevails as to the need for a five-year guarantee, but the correct tensile-specific wording must be clarified before execution.
The tender cover prints 08.06.2026, while the signed NIT notice, schedule and corrigendum reference identify 08.07.2026. The detailed NIT schedule date of 08/07/2026 prevails for publication and eligibility calculations because it is the specific e-publication schedule corroborated by the corrigendum.
The NIT expressly says JV is not applicable and prohibits JV for works up to Rs. 2 crore, yet later generic sections print JV experience, turnover and document rules. For this Rs. 79,56,629 tender, the specific prohibition prevails; bidders should not bid as a JV.
The original NIT accepts general building/structural-steel work including concrete foundations, while Corrigendum 1 restricts similar work to tensile fabric structures. The corrigendum is later and expressly amends Clause 8.A, so the tensile-fabric definition prevails.
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.
Please issue a corrected Annexure X for the five-year tensile-fabric roofing guarantee, confirming covered defects, exclusions, start date, rectification response time and whether the Rs. 10 notarized format is required. The current annexure is drafted only for waterproofing treatment and cannot be executed literally for the specified structure.
Please identify the VNIT department/contact, prescribed submission package, governing design codes and loads, expected review fees and turnaround, number of review cycles, and the document that constitutes acceptance. Also confirm whether WCL-caused/VNIT-caused delay beyond 21 days extends the 90-day completion period without LD.
Please provide the architectural/approved canopy drawings, support coordinates and levels, geotechnical/foundation inputs, exact design wind speed and load combinations, drainage interface, and approval responsibilities. The BOQ requires the canopy to match AGM-office architecture and withstand local peak wind speeds but gives no numerical wind speed or tender drawing in the issued folder; these inputs materially affect steel, fabric patterning and foundations.
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 entire VNIT-vetted design must be completed before work starts and within 21 days of LOA, inside an overall 90-day completion period. Delay exposes the contractor to LD of 0.5% of contract/revised contract amount excluding GST per week or part, capped at 10%, and possible termination/debarment.
The specialized-work security attributable to the tensile item remains locked until expiry of the five-year guarantee unless released after 12 months against equivalent BG. BGs must run 90 days beyond the guarantee. The contractor must rectify defects at its own cost, while the supplied guarantee form is mismatched to waterproofing, creating uncertain warranty scope.
Rates remain fixed for the 90-day contract, price variation is expressly not applicable, and no mobilization advance is payable below Rs. 10 crore. The bidder must finance early design, VNIT fees, fabrication, fabric procurement and foundations from its own working capital, subject to monthly/interval RA certification.
Normal performance security is 5% excluding GST and 5% retention is deducted from RA bills. If the quote excluding GST is more than 15% below the estimated/justified cost, additional performance security equals the difference between 85% of that cost and the quoted price; failure to furnish it causes cancellation, EMD forfeiture and at least one-year debarment.
BOQ quantities are estimates; WCL may alter, add, substitute or omit work without invalidating the contract. Extra-item rates may be fixed by analysis and disputed rate decisions are final at the stated accepting-authority level. Payment depends on measurement and EIC certification, and final payment requires a no-claim certificate and royalty proof.
If WCL loses input-tax credit because of the contractor's return, tax-payment or invoice failures, WCL may recover the tax and cess from current bills or other dues with interest and penalty. A later GST-status change is paid at the tender-stage basis or actuals, whichever is lower.
