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.
The invitation specifies Registered Class I Contractors (Civil). Detailed clauses permit individual, proprietary, partnership, limited-company/corporation and JV bids, subject to their signing and evidence rules.
Turnover: Rs.1.53 crore in any one of FY 2020-21 to 2024-25 and Rs.0.67 crore in any two of those years. Minimum cash flow is Rs.1.02 crore. Available bid capacity [A×N×1.5−B] must exceed Rs.2.04 crore; N=0.50 year. Corrigendum 1 changes the updating basis for A and B from 2025-26 to 2026-27 price level, with A updated at 6% per annum.
In the last five years, 100% completed and commissioned water-supply scheme(s): one agreement worth at least Rs.0.82 crore, or two agreements with stated aggregate threshold Rs.1.22 crore. Government/quasi-government experience certificates must be issued by an officer not below Executive Engineer; private-work evidence additionally needs photographs, senior-official certification, countersignature by a Government engineer not below Assistant Executive Engineer, notarization, and tax/financial evidence.
Over the last five years: MS pipeline supplied/laid/jointed/tested/completed—27.00 m aggregate, including 4.50 m of 219.1 mm dia or higher; DI/CI pipeline—2,133.00 m aggregate, including 355.50 m of 100 mm dia or higher; pumping machinery—0.90 kW aggregate, including one 0.75 kW or higher pump.
For offered goods, submit documentary evidence of production/sales and manufacturer credentials including the manufacturer auditor’s certificate. Stated minimums are 5 years in production and 50 submersible pumps/year; 5 years and 200 valves/year above 200 mm; PVC pipes at 200% of required length.
For this Rs.2.04 crore work, a lead partner plus one JV partner is permitted. JV participation must be at least 25% of tender value; partners collectively meet physical criteria, while each separately meets financial criteria. Lead must meet at least 50% and each other partner at least 25% of turnover and bid-capacity requirements; all collectively meet 100%. Any one partner may meet the similar-work criterion. Partners are jointly and severally liable.
Proposed subcontracts require Annexure XI and relevant experience. A subcontractor must have completed and commissioned at least two similar works in the last five years, cannot further subcontract, and each subcontract is capped at 15% while total subcontracting is capped at 60%. Prior written notification applies where a subcontract exceeds 10%. Subcontractor experience does not qualify the main bidder unless prior subcontract work was properly approved and fully evidenced.
The bidder must not be associated with the design/supervision consultant. Disqualification applies for false/misleading submissions, poor performance in the prior five years (including abandonment, rescission attributable to the contractor, inordinate delay, adverse litigation history or bankruptcy), or current debarment/blacklisting by any Central/State government body.
What is being procured: the work, supplies or services, deliverables and quantities, locations, phases, completion or delivery timelines, applicable standards, and notable exclusions.
Procurement and construction of a complete water-supply system from the existing 4.00 LL Rameswaram Municipality sump to the Indian Navy 4N Detachment sump at Olaikuda, Ramanathapuram District, including supply/installation of materials, machinery and equipment, testing, commissioning and maintenance.
Design requirement is 1.00 LL water supply and 1.10 LL including 10% transmission loss, pumped 12 hours/day. The 7,200 m main is stated as 7,038 m of 100 mm DI K7 S/S, 72 m of 100 mm DI D/F and 90 m of 100 mm GI medium pipe. Pump duty is 153 lpm at 18 m head; 406.4 mm dia, 6.3 mm thick MS encasing is 90 m.
BOQ packages the principal deliverables as supply/delivery of the 100 mm pipeline, supply/delivery/erection/commissioning of pump sets, and one year of scheme maintenance. It also includes allied laying, specials, valves/chambers, testing, restoration and appurtenant works.
Construction is 6 months, followed by a 3-month trial run and 12 months paid maintenance. Milestones are 30% by month 2, cumulative 65% by month 4 and 100% by month 6. Work must conform to relevant BIS, TNBP and the bid specifications/quality parameters.
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 two separate online files at https://tntenders.gov.in: Part I for technical/eligibility evidence, bid security and certificates; Part II for the price bid only. No price indication may appear in Part I.
All documents must be digitally signed. The bidder must register on the portal and hold a valid DSC on smart card/e-token; the time-stamped unique bid ID is the acknowledgement.
Individual/proprietor/partnership/company bids must follow entity-specific signatures. Proprietor and all partners/POA signatures require notary attestation; registered POAs and partnership deed copies accompany applicable bids. Bid language is English; other-language support must have an accurate English or Tamil translation.
Clause 24.2 refers to receipt of original EMD/EMD-exemption documents by bid opening, but the tender otherwise requires online payment/eBG and gives no physical-delivery address, list, or deadline. Obtain portal clarification before relying on a physical submission.
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.
Amendment Slip dated 15.07.2026 changes only the bid-capacity updating basis: A changes from 2025-26 to 2026-27 price level (still 6% per annum), and B changes from 2025-26 to 2026-27 price level. N remains 0.50 year and B remains commitments/on-going work due in the next 6 months. Bidder action: recalculate bid capacity on the 2026-27 basis, sign the amendment slip, and append it in Technical Bid Cover 1.
No date, amount, scope or other condition is amended. Final submission is 23.07.2026 at 15:00, opening 24.07.2026 at 15:30, approximate value Rs.2.04 crore, EMD Rs.1.53 lakh, and bid capacity must exceed Rs.2.04 crore calculated with A and B updated to 2026-27 price level.
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.
Bid-document salient details split the 7,200 m main into 7,038 m DI K7, 72 m DI D/F and 90 m GI medium. BOQ item 1.01 instead calls for 7,200 m of 100 mm DI K7. Neither Corrigendum 1 nor an order-of-precedence clause resolves this pricing conflict. Seek a corrected BOQ; do not silently price one interpretation.
The salient details specify an “Openwell Submersible” pump set, while BOQ item 1.02 specifies a “Horizontal Open well” pump set at the same 153 lpm × 18 m duty. Corrigendum 1 does not amend this. Obtain written confirmation and a corrected BOQ/specification before selecting and pricing the pump.
The bid-security clause requires online payment or eBG through the portal, but bid-opening Clause 24.2 says bids will be rejected if “original EMD/EMD Exemption Document” has not been received. No physical-original mechanics are stated. The specific current payment clause supports online/eBG, but the rejection wording remains unresolved and needs portal clarification.
Corrigendum 1 cites the IFB reference as dated 01.07.2025, whereas the tender notice and bid document identify IFB No.01 as dated 01.07.2026. The subject/work and amendment date identify this tender; use the 2026 IFB reference while retaining the signed corrigendum as issued.
The invitation states eligibility is limited to Registered Class I Contractors (Civil), while ITB Clause 6 says the invitation is open to any bidder meeting requirements and expressly accepts JVs. The detailed qualification clauses do not explain whether every JV member, only the lead, or the JV itself must hold Class I registration. Treat Class I registration as a notice-level pass/fail requirement and seek confirmation for JV structuring.
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.
Confirm whether the payable pipeline is 7,038 m DI K7 + 72 m DI D/F + 90 m GI, or 7,200 m DI K7 as BOQ item 1.01 states; issue a revised BOQ that separately quantifies every pipe material and joint type.
Confirm whether bidders must supply an open-well submersible pump or a horizontal open-well pump, and issue the controlling technical data sheet/make approval basis.
State whether TWAD/Tamil Nadu Class I Civil registration is required from the lead only, every JV partner, or the JV entity, and whether registration after award under Clause 33.1 can cure absence at bid stage.
Confirm that online EMD/eBG requires no physical original, or specify exactly which original/exemption document must reach which address and by what time before the 24.07.2026 opening.
Annexure XII is mandatory, but the only staffing/penalty table printed applies to works above Rs.50 crore while this work is Rs.2.04 crore. Confirm the minimum staff, qualifications, headcount and penalties applicable to this contract.
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.
There is no price adjustment and no mobilization advance. The bidder bears material, fuel, labour and financing escalation over construction, trial run and paid maintenance.
Milestone delay attracts LD of 0.05% per week on unfinished work, capped at 10% of total contract value, without prejudice to termination. Defective construction can additionally attract a penalty up to 10% of the defective work value plus rectification at the contractor’s cost.
Monthly bills may take up to 6 weeks; 5% is retained from each running bill. Construction reaches 100% only against a 5% two-year BG, and final payment follows completion of O&M. The 24-month defect period restarts from rectification of defects, and performance security is held through that period.
The contractor bears electricity during construction and trial run, plus water, gas, consumables, chemicals, spares and tools during O&M unless explicitly reimbursable. Daily multi-shift O&M staffing and accommodation/amenities are contractor obligations; only normal O&M electricity is borne by the Employer.
The Employer may foreclose all or part of the work for any reason without compensation for lost profit/advantage. Losses and other amounts may be set off across contracts, securities sold, residue recovered legally/revenue recovery, and post-payment technical audit may order recovery even after payment.
The unresolved pipeline-material and pump-type conflicts materially affect procurement, hydraulics, costing and manufacturer eligibility. Do not commit suppliers until clarified.
The inviting authority and relevant contacts: office, person, designation, address, phone and email — and which address receives physical submissions, if any.
