Removal of Legacy Waste through Biomining

Bid submission window

Online bid submission starts 24.08.2026 from 11:00 AM and closes 17.09.2026 at 3:00 PM; if that day is a holiday, receipt/opening shifts to the next working day at the same time and venue.

• Portal: https://tntenders.gov.in (online only per NIT).

Pre-tender / pre-bid meeting

Pre-tender meeting on 02.09.2026 at 11:00 Hrs at Nagercoil City Municipal Corporation.

• Non-attendance does not disqualify a bidder; amendments from the meeting (if any) will be only by Addendum.

Bid opening

Technical bid opening on 18.09.2026 at 11:00 AM / 11.00 hrs at the Office of Nagercoil City Municipal Corporation; financial bids of qualified bidders open later on intimation.

• Opening is in presence of tenderer representatives.

Bid validity

Tender validity is six (06) months / 180 days after the deadline for tender submission; shorter validity is non-responsive.

• If EMD is requested on extension, it must be extended for 30 days beyond the extended validity deadline.

Publication / notice date

NIT / short re-tender bulletin is dated 22.08.2026; bid submission start is 24.08.2026.

Post-award commencement milestones

Plant installation must start within 21 days of LOI; performance security within 7 days of LOA; DBFO agreement within 7 days of furnishing performance security; plant installation completion within 3 months of LOI/LOA; biomining task completion within 6 months from agreement/award.

• TDS also states a 1-year Performance Period reckoned from substantial completion of construction.

Estimated tender / project value

Estimate / project cost is Rs. 420.00 lakhs (Rs. 4.20 crores).

• BOQ quantity is 51,122 MT for biomining reclamation (rate to be quoted by bidder).

EMD / bid security

EMD is Rs. 4.20 lakhs / Rs. 4,20,000, to be remitted online in the name of 'The Commissioner, Nagercoil City Municipal Corporation' (payable at Nagercoil).

• EMD validity: till signing of Bio-mining Contractor Agreement and providing performance security.
• Any tender without enforceable/compliant EMD is non-responsive.
• Successful tenderer's EMD returned after agreement signing and furnishing performance security.
• Online e-tender instructions also say the original EMD should be posted/couriered/given in person within tender submission date & time and scanned copy must match — conflicting with pure online EMD wording (see contradictions).

Tender / RFP document fee

TDS states RFP document cost is Rs.15,000 only (inclusive of all taxes); documents can also be downloaded free from www.tntenders.gov.in.

• NIT states bid document is available at free of cost on http://tntenders.gov.in.
• ITT 7.1 / List of Attachments still contemplate Document Fee receipt or DD; missing fee is a non-responsiveness ground under ITT 15.3.
• Treat free e-download as the operative NIT rule, but clarify fee/DD obligation before bid (see contradictions / pre-bid).

Performance security and additional security deposit

Performance security is 5% of contract value, as unconditional irrevocable bank guarantee from any scheduled bank in India acceptable to the TIA, within 7 days of Letter of Acceptance, valid for the entire Contract Period.

• Additional SD: (i) any plus % and up to (-)5% over departmental value — no additional SD; (ii) between (-)5% and (-)15% — 2% of estimated value; (iii) between (-)15% and (-)20% — 50% of difference between estimated and quoted value.
• BG format is said to use a format given in the Tender Document, but no separate BG proforma is printed in the supplied pages.
• If tender is seriously unbalanced/front-loaded, TIA may require increased performance security after price analysis.

Payment terms and pricing basis

Payment is a tipping fee at the bidder’s accepted quote, certified by a third party; BOQ/financial evaluation is on rate per MT, while TOR payment clause says monthly payment on cubic-metre basis.

• Key activity flow: third-party verification of value of work done on biweekly basis; payment on third-party certificate.
• Currency is Indian Rupees; selection is least-cost / L1 among technically qualified bidders.
• Contractor must install calibrated electronic weighbridge with online monitoring access for Authority/PMC.

Technical experience – biomining quantity

Bidder must have completed biomining work quantity equivalent to BOQ quantity 51,122 MT (volume conversion factor 1 m³ = 0.8 MT) in a single agreement in any one financial year among 2021-22 to 2025-26, with engineer-in-charge proof; missing proof makes the bid invalid.

• Evaluation matrix further requires legacy waste reclamation (biomining) works of value not less than Rs.4.20 crore in a single agreement in any of FY 2021-22 to 2025-26, with agreement and experience certificate from Municipal Corporation/ULB certified by officer not below Executive Engineer; minimum one experience document is mandatory else bid invalid.

Class I registration and key personnel

Bidder must be a currently live CLASS I contractor registered with any State Government Department/Board/Government Undertaking; key personnel required are Site Engineer (BE Civil) – 1 No and Site Supervisor (DCE) – 1 No.

Financial turnover and working capital

Bidder must show past five years’ turnover and annual minimum turnover not less than 100% of value put to tender (Rs.420.00 lakh) in any one of the preceding five years, with CA proof; working capital must finance at least 15% of value put to tender.

• LOI year windows conflict between 2020-21 to 2024-25 and 2021-22 to 2025-26 (see contradictions).
• Working capital = bank balance on application date + unutilized OD/credit facility from Nationalized/Scheduled banks.
• All supporting certificate copies must be attested by Notary Public / officers not below Executive Engineer.

Consortium / JV rules

Evaluation criteria expressly state 'No Joint Venture is allowed' and experience must be in the bidder’s own name; yet glossary and tender forms provide Contractor-of-Firms / lead-partner JV formats.

• Treat sole-entity bid as the safe pass/fail position unless authority clarifies otherwise.

Debarment / termination / integrity bars

Bidders whose biomining/legacy waste/MSW or similar contracts were terminated for contractor default by any Government/ULB/agency/PSU in the last five years are ineligible; Letter of Tender requires certification of not being declared ineligible by GoI/TIA/Corporation and no corrupt practices.

• Corrupt, fraudulent, collusive or coercive practices lead to rejection/sanctions under ITT corrupt practices clauses.

Technical evaluation threshold and scoring

Only bidders scoring minimum 70 marks in pre-qualification/technical evaluation qualify for financial bid opening; L1 among qualified bidders is selected.

• Mark heads include Profile, Experience (25), Vendor tie-up (20), Vehicles/machineries (10), Methodology (20), RDF disposal experience (20).
• RDF marks: 5,000–10,000 MT = 5; 10,000–25,000 MT = 10; more than 25,000 MT = 20 in a single project in last 5 years.

Work package and location

Open tender works package for removal/reclamation of legacy waste at Valampurivilai compost yard, Nagercoil City Municipal Corporation, through biomining process under SBM 2018-19.

• Background study figure of about 100,000 cum differs from approved project quantity 63,903 cum.

Quantity obligation (dual MT and volume)

Approved project quantity is 51,122 MT corresponding to estimated 63,903 cum; contractor must process minimum 63,903 cum and also achieve 51,122 MT — meeting only one metric does not relieve the other; no claim for density/weight-volume variation.

Process deliverables and standards

Design-build-finance-operate style biomining: excavate, stabilize with bio-culture/windrows, screen/segregate into recyclables, fines/compost, RDF/incinerables, inerts and hazardous waste; dispose 100% with zero rejects; reclaim land for Corporation use.

• Contractor installs weighbridge + online monitoring; temporary fencing; ensures ~150 kVA electrical power; pays EB and fleet costs; obtains statutory clearances at own cost.
• Stacking limits conflict: 15 days vs one month (see contradictions).

Completion and contract duration

Legacy waste removal/reclamation task is to be completed within 6 months from date of agreement/award; plant installation start within 21 days of LOI and complete within 3 months of LOI/LOA.

• Conflicting longer periods also appear: site handover/contract period 1 year; Contractor Agreement validity 3 years (see contradictions).

Submission mode and portal

Bids are to be submitted online through the e-tendering portal https://tntenders.gov.in / www.tntenders.gov.in; NIT states only online tenders are accepted.

• Register on portal, obtain e-token/Digital Signature, upload virus-free files (individual docs preferably <2 MB; total ≤12 MB as stated).
• TDS also describes offline sealed envelopes — conflicting with NIT online-only rule.
• Subject line: “REMOVING THE LEGACY WASTE DUMPED IN THE COMPOST YARD THROUGH BIO-MINING PROCESS AT NAGERCOIL CITY MUNICIPAL CORPORATION”.

Cover structure and digital signing

Technical proposal is Cover A / technical module; Financial proposal is Cover B / financial module; online documents are digitally signed using the bidder’s e-token.

• If offline path were used: original + one copy; all pages numbered/bound and signed/initialed.

Physical originals / offline delivery

E-tender instructions require the original EMD to be posted/couriered/given in person to the Tender Inviting Authority within tender submission date & time; scanned online copy must match the physical instrument.

• This sits awkwardly with TDS online EMD payment wording — clarify before bid.

Signing and attestation rules

Tenders must be signed by a duly authorized person under Valid Power of Attorney; supporting qualification certificates must be attested by Notary Public or officers not below Executive Engineer.

• Contractor Agreement (if multiparty): NJ stamp Rs.100/- notary attested.
• Lead Partner PoA format: NJ stamp Rs.50/- notary attested.
• Forms must be completed without alteration to text; all blank spaces filled.

No corrigendum / addendum in the tender pack

The downloaded workspace contains only the NIT, bid document and BOQ; no corrigendum or addendum file is present, and tender metadata lists an empty corrigenda array.

• Final applicable dates/values are those in Tendernotice_1.pdf and bid-doc-biomining.pdf / BOQ as issued.
• Bidders remain responsible to re-check https://tntenders.gov.in for any later addendum before submission.

Payment / quote unit: MT vs cubic metre

BOQ and selection are per MT/ton, interim measurement is in MT, but TOR payment clause pays monthly on cubic-metre basis and the Financial Proposal letter header refers to processing one cum.

• Prevailing commercial form for bidding appears to be portal BOQ rate per MT; seek written clarification on payable unit and conversion.

Contract / performance period: 6 months vs 1 year vs 3 years

Task completion is repeatedly 6 months, but site handover/contract period is also stated as 1 year, Contractor Agreement validity as 3 years, and Performance Period as 1 year from substantial completion.

• Bidders should lock which clock governs LD/extension, land use and security validity before pricing.

Joint Venture banned vs multiparty forms provided

Section II evaluation says 'No Joint Venture is allowed', but glossary defines Applicant as single entity and/or Contractor of members and full Contractor Agreement / Lead Partner PoA formats are printed.

• Safe reading until clarified: sole bidder only; multiparty submissions risk rejection under evaluation matrix.

Document fee free vs Rs.15,000 and fee non-responsiveness

NIT/LOI say free download from tntenders, while TDS prices RFP at Rs.15,000 and ITT 15.3 rejects bids without Document Fee receipt/DD.

Online-only tender vs offline submission instructions and physical EMD

NIT accepts tenders only online, but ITT/TDS still describe offline sealed envelopes and require physical original EMD delivery matching scanned copy.

• TDS ITT9 says EMD through online; ITT 17.2.8 still requires original EMD to be sent to TIA.

Financial year windows for turnover/experience inconsistent

LOI cites both 2020-21 to 2024-25 and 2021-22 to 2025-26 windows for turnover/experience proofs.

• Technical biomining quantity criterion uses 2021-22 to 2025-26; similar-work 50% value criterion uses 2020-21 to 2024-25.

On-site stacking limit 15 days vs one month; site name Dasayapalli vs Valampurivilai

Object clause limits stacking retrieved material to 15 days (and BOQ says sell/dispose within fifteen days), while responsibility 4.1 allows final archive up to one month; some boilerplate still names Dasayapalli compost yard instead of Valampurivilai.

• TOR 4.2 also contains an apparent typo requiring collection of 'not less than 51122 MT per day'.

Asset handover at end of project

TOR 4.5 says the Developer/Contractor will not handover all assets and machines at project end, while Letter of Tender (m) commits to turn over all equipment/materials/spares free of cost.

Confirm payable unit and measurement protocol (MT vs cum)

Ask authority to confirm whether running/final bills are paid on weighbridge MT, on surveyed volumetric reduction (cum), or both, and how the dual 51,122 MT / 63,903 cum obligation is billed if density differs.

• Material to unit-rate pricing and cash flow because TOR 7.1, interim payment clause and BOQ conflict.

Is Joint Venture permitted despite evaluation ban?

Seek written ruling whether multiparty/JV/'Contractor of firms' bids are acceptable, given evaluation says no JV while forms exist.

• Determines bid structure and whose experience/turnover counts.

Which contract duration and securities validity apply?

Clarify governing period among 6-month completion, 1-year contractor/performance period and 3-year agreement validity, and corresponding performance-security validity/release.

Document fee and physical EMD still required for free online bids?

Confirm whether Rs.15,000 fee receipt/DD and physical EMD instrument are mandatory when tender is downloaded free and EMD is paid online on tntenders.

• Non-responsiveness risks under ITT 15.3 and ITT 17.2.12 if not clarified.

Joint-survey quantity vs dual minimum obligation and grant quantity

Ask how joint-survey final quantity interacts with mandatory 51,122 MT and 63,903 cum floors, and with background 100,000 cum study quantity / possible 1-year extension for excess waste.

• Also clarify daily target (335 MT/day) versus TOR 4.2 typo of 51,122 MT per day.

End-of-project plant ownership and liquidated damages schedule

Request clarification whether plant/machinery stays with contractor or is handed over free, and the specific LD/penalty rates for delay or shortfall (not quantified in the bid document).

• No numerical LD/penalty schedule found in the extracted bid document; only forfeiture/cancellation triggers for post-award milestones.

Tight 6-month production and dual quantity risk

About 51,122 MT / 63,903 cum must be biomined and fully disposed in 6 months (~335 MT/day), and both MT and cum minima apply with no density-variation claims.

• Plant must start within 21 days of LOI and be installed within 3 months or contract can be cancelled.

Zero-reject disposal and off-site offtake risk

Contractor must dispose 100% recovered fractions within short stacking limits, arrange vendor/RDF/hazardous-waste outlets, and still score vendor-tie-up/RDF experience in evaluation.

• Failure of offtake markets directly threatens daily progress and payment certification.

Payment, security and cancellation cash-flow risk

Payment depends on third-party certification (monthly/biweekly) with conflicting MT/cum bases; 5% performance BG plus possible additional SD for low quotes; EMD forfeitable; failure to give PS in 7 days or sign agreement in 7 days can cancel award.

• No quantified liquidated-damages schedule found in the bid pack — residual risk if later imposed via agreement/conditions of contract referenced but not fully supplied.

Statutory compliance, environmental and land-use constraints

All clearances/licenses are contractor’s cost and risk; process must meet MoEF&CC/CPCB/TNPCB/NGT/MSW rules; municipal land cannot be mortgaged for finance; ambient air quality and public-complaint risks sit with bidder.

• Contractor also installs weighbridge with Authority/PMC online access — operational transparency and data disputes possible.

Document inconsistency / rejection-process risk

Multiple internal conflicts (fee, JV, periods, units, online vs physical) create high risk of non-responsiveness if the authority applies the stricter reading.

Tender Inviting / Accepting Authority

Tender Inviting Authority is The Commissioner / Municipal Commissioner, Nagercoil City Municipal Corporation; Tender Accepting Authority is the Municipal Council.

• Executive Authority is also the Municipal Commissioner.
• Tender Scrutiny Committee is headed by the TIA; Commissioner is appellate authority for unresolved issues at committee level.
• NIT signed for Commissioner; City Engineer / Deputy City Engineer countersignatures dated 22/8/2026.
• No phone number or email address is printed in the supplied NIT or bid document.

Addresses for clarification, pre-bid and physical submissions

Pre-tender meeting, bid opening and offline/physical delivery address is the Office of Nagercoil City Municipal Corporation / Municipal Commissioner, Nagercoil.

• EMD online beneficiary name: The Commissioner, Nagercoil City Municipal Corporation, payable at Nagercoil.
• Portal for tendering: https://tntenders.gov.in / http://tntenders.gov.in / www.tntenders.gov.in.
• NIT estimate no. 4/2026-27/CE or 04/26-27/CE.
