120 days from the date of opening of the tender, including any extension; the bid may not be withdrawn after submission until validity expires.
Tender value or estimated cost, EMD/bid security (amount, acceptable forms, validity), tender document fees, performance security, and key payment terms.
No tender value or estimated cost is stated in the tender documents or BOQ; the BOQ requires a per-MT basic rate and shows no prefilled estimated rate.
Rs.1,180/- (Rupees One Thousand one hundred and eighty only), non-refundable, payable online.
Rs.1,18,000/- (Rupees One Lakh Eighteen Thousand only), payable through the TN Tenders online payment gateway only; the exact amount is required, no interest is paid, and no EMD validity/claim period is stated.
The successful tenderer must provide 5% of total contract value within 30 days of the work order, by scheduled-bank demand draft payable at Chennai or irrevocable bank guarantee (physical BG or electronic BG). The tender states the calculation as L1 rate × 10,000 MT × 5%, plus GST @18%; no BG validity or claim period is specified.
100% payment is based on the lower of mine-origin and delivery-point weighments. Proper certified bills are paid at Head Office every fortnight / calendar month; no advance is available. Registered MSMEs may receive payment through TNTReDS subject to portal conditions.
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.
Arrange one Excavator of the stated 200 LC or 210 LC & above capacity and at least one lorry, owned or hired, with manufacturing year not older than 2019; submit invoices and, for hired machinery, hiring proof and owner agreement.
Minimum turnover of 60 lakh per annum, evidenced by audited annual accounts for any one of the three preceding financial years 2023-2024 to 2025-2026.
PAN card and GST registration certificate are mandatory.
Through Annexure-IV, the bidder certifies that the firm has not been banned by Government for unfair business dealings with Government Departments/Undertakings and has no pending litigation against TAMIN.
The tender specifies no prior-work experience threshold, net-worth test, consortium/JV qualification rule, or separate professional registration/certification beyond PAN and GST.
What is being procured: the work, supplies or services, deliverables and quantities, locations, phases, completion or delivery timelines, applicable standards, and notable exclusions.
Systematically excavate and dewater raw silica sand using the contractor’s own manpower and machinery; load it into the contractor’s lorries at Mudaliyarkuppam SF.No.319/1 & 319/5 Silica Sand Mines and transport/deliver it on a tonnage basis to TAMIN’s Indian Standard Sand Unit, Ennore, Chennai.
Total allotted quantity is 10,000 MT: 5,000 MT up to 30.11.2026 and 5,000 MT from 01.12.2026 to 30.11.2027. The bidder must also be capable of additional quantities if TAMIN requires them.
Remove and stock overburden/contaminated sand within the lease; dewater as required; move raw sand to the drying yard, dry it and remove clay/particles as directed; stack or load as instructed; and refill the mined area with previously removed waste sand after mining.
Work runs up to 30.11.2027 from contract execution or until completion of the EC-permitted quantity, whichever occurs earlier. TAMIN may consider a further three-month extension based on performance and production, at the same rates and terms.
Provide the required excavator/lorries, sufficient manpower, operators/drivers, diesel, oil, consumables and approved safety equipment at contractor cost; comply with DGMS and other statutory authorities, Mines Act, MMDR Act, labour laws, insurance, EPF/ESI and minimum-wage obligations.
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 through https://tntenders.gov.in. Uploads elsewhere are not considered and hard-copy applications are not entertained; no physical originals are requested with the bid.
The online bid has a technical-bid document set and a separate financial bid in the supplied BOQ. Only technically eligible bidders’ financial bids are opened; shortlisted bidders then participate in reverse bidding.
Register on the Tamil Nadu Tender portal and obtain a DSC, which is essential. Ensure the registered email and DSC remain valid, and click “Freeze bid” to complete submission; otherwise the bid is not submitted/openable.
Annexure-II must be duly signed; its declaration calls for the authorized signatory’s name/designation, signature and office seal. Annexure-IV provides signature, signer status, company/firm, date and seal fields. Do not alter the BOQ structure or filename.
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.
The AI found nothing to report for this question.
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.
Clause 2 fixes the contract up to 30.11.2027 (or earlier EC quantity completion), while Clause 23(iii) says the agreement is valid for one year from execution; both also mention a three-month extension. For bid planning, the dated quantity schedule and specific Clause 2 end date should be used, but TAMIN should clarify the agreement wording before award.
The title and eligibility Clause 8(1) say “200 LC or 210 LC & above”, but Clause 11 and technical-bid Clause 17(c) say “200 LC or above”. The pass/fail eligibility clause is more specific and should prevail pending clarification; a model between 200 LC and 210 LC is otherwise ambiguous.
The stated work is excavation, dewatering, drying, loading and transport, but the general conditions call the bidder a drilling-and-blasting contractor and require drilling/blasting under DGMS norms. No drilling/blasting item appears in the BOQ. The detailed scope and BOQ should govern pricing, but this boilerplate creates an unresolved contractual obligation requiring clarification.
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.
Will the contract terminate on 30.11.2027 regardless of execution date, or run for one year from execution under Clause 23(iii)? Also confirm how the two 5,000-MT periods apply if the work order is delayed.
Does any excavator rated 200 LC and above qualify, or are only 200 LC and 210 LC-and-above models accepted? Confirm the documentary method for proving model year/capacity, particularly for hired equipment.
Confirm that drilling/blasting is excluded. If included, provide quantities, geology, explosive/licence responsibilities, method specifications and a BOQ payment item.
Confirm whether the 5% is computed on the GST-inclusive or GST-exclusive contract value, reconcile “Plus GST @18%”, and provide the required BG validity, claim period and prescribed wording.
Provide the approved haul route and distance to Ennore, toll/permit and unloading responsibilities, expected trip/dispatch schedule, mine and delivery weighbridge rules/tolerances, and site information on overburden, groundwater/dewatering and drying-yard capacity.
Clarify whether invoices are processed fortnightly or monthly and state the contractual payment due date after certification, including the process for resolving origin/delivery weighment differences.
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 bidder must hold the rate through the full term and any three-month extension, may be required to handle additional quantity, and can be terminated if production/transport targets are not met. No price-escalation mechanism or guaranteed minimum beyond the allotted schedule is stated.
Payment is only on the lower origin/delivery weight, with no tolerance or dispute mechanism. The contractor funds all investment and operating inputs with no advance, while the payment cycle is ambiguously “fortnight / calendar month”.
The tender deems the contractor to accept mineral quality and mine conditions after field visit and allows EMD/security forfeiture for later withdrawal. Overburden removal, dewatering, drying/cleaning and refilling are included without measured BOQ quantities.
The 5% security deposit earns no interest, may be forfeited for any breach, and TAMIN may deduct bidder dues and its litigation/dispute expenses; refund follows completion and Unit Officer NOC, with no release deadline.
The contractor bears wages, EPF/ESI/bonus, insurance, safety compliance and all accident/death compensation. TAMIN accepts no responsibility for these liabilities; statutory deductions may be made from payments.
TAMIN may cancel/reject/withdraw/extend without reasons, accept the tender in whole or part with modifications binding on bidders, and requires disputes to be filed only in competent Chennai courts.
If more than five bidders qualify, the qualified bidder(s) with the highest initial price offer are eliminated before reverse bidding; the initial quote therefore affects both shortlist survival and auction base.
