Two-cover item-rate e-tender under TWAD Board, Chief Engineer/Thanjavur.
IFB/Contract No.: 01 /F.WSS to SIPCOT- Jeyankondam /SDO/CE-TNJ/2026/Dt.17.06.2026.
BOQ header row once states "PROVIDING 1.10 MLD" while work name everywhere else is 1.00 MLD — see contradictions.
Key components and quantities
Salient components: Infiltration Well 4.50 m dia × 12 m depth – 1 No. at Thenkachiperumalnatham; DI connecting main (250 mm D/F lengths); 250 mm OPVC 12.5 KSC pumping main 27,000 m plus 20 m DI; Control Room 3 m × 4 m – 1 No.; RCC sump 65,000 litre – 1 No.
Connecting main DI: 250 mm D/F (3 m)–114 Nos; (2 m)–3 Nos; (1 m)–2 Nos.
Physical eligibility basis cites total pipeline length 26.774 km and pump requirement 67.14 kW / highest 33.57 kW; sump 0.65 LL — slight length variance vs 27,000 m OPVC in salient details.
BOQ includes infiltration well in River Coleroon near Thenkachiperumalnatham, pumping main materials & civil, open-well submersible pumpsets, valves, chambers, flowmeters and allied works.
Location
SIPCOT Industrial Park at Jeyankondam/Jayankondam in Ariyalur District, Tamil Nadu; infiltration well near Thenkachiperumalnatham / River Coleroon.
Section I construction 12 months from start (28th day from work order) with quarterly financial milestones, then 3-month trial run/commissioning/guarantee performance; Section II paid maintenance 12 months.
If satisfactory trial run completed within three months, contractor maintenance can commence on completion of trial run with minimum continuous designed supply for one month.

Standards: relevant BIS, TNBP, bid documents; water-tightness testing per IS 3370 (Part-I) 1965 as amended.
Required documents & submission
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.
32
Submission mode and portal
Electronic two-cover submission only on https://tntenders.gov.in; Part I Technical Bid and Part II Price Bid as separate online files; all documents digitally signed.
Bidder needs portal enrolment/registration and valid DSC (smart card/e-token) from authorised CA (e.g. Safescrypt, e-MudhraCA).
After online submission the system generates a unique time-stamped bid ID as acknowledgement.
No rates/prices in technical bid/first cover; Part II contains Price Bid alone.
Bid documents non-transferable; conditional tenders liable for rejection; alternative proposals not considered.
Language: English (supporting docs may be other languages with accurate English/Tamil translation).
Bids may be modified online any number of times before deadline; withdrawal after submission not allowed; modification after deadline may forfeit bid security.
Signing, attestation and physical originals
Online digital signing is primary; many identity/experience documents require Notary attestation. Bid security is online/e-BG only. Clause 24.2 also refers to original EMD at opening (conflicts with online-only EMD).
Proprietor/partner/authorised-signatory signatures to be Notary-attested as applicable (Clauses 2.2–2.4).
Registered Power of Attorney for bid signatory (7.1.2).
No separate general requirement for physical submission of technical envelopes is stated beyond online e-submission; agreement stamp paper Rs.100 after award.
Certificate that no correction/alteration was made to downloaded bid document and bidder will abide by all terms.
Corrigendum analysis
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.
1
No corrigendum / addendum found in the tender pack
The supplied documents contain only Tendernotice_1.pdf, BidDocument.pdf and BOQ_827814.xls. No corrigendum, addendum or pre-bid reply document is present, so original document values apply as written (subject to internal conflicts noted under contradictions).
Bid document contemplates addenda/corrigenda via the portal (latest corrigendum on tntenders.gov.in) but none are included in this workspace pack.
Finally applying key values remain those stated in BidDocument/BOQ: approx value Rs.12.86 Cr; EMD Rs.9.65 Lakh; submission 31.07.2026 15:00 per cover/Cl.21.1; pre-bid 09.07.2026 11:00; validity 120 days from technical bid opening.
Contradictions
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.
6
Bid submission deadline: 31.07.2026 vs 24.07.2026
Cover page and ITB Clause 21.1 fix online submission at 31.07.2026 15:00, while the IFB summary table states Bid Submission 24.07.2026 upto 15:00 and download end 24.07.2026.
Operative detailed clause for deadline is Clause 21.1 (and cover page) stating 31.07.2026 3:00 P.M.
IFB download window ending 24.07.2026 is inconsistent with a 31.07.2026 submission date unless later amended on the portal.
Bidders should confirm the live portal critical dates on https://tntenders.gov.in before bidding.
Bid opening date earlier than detailed submission deadline
IFB states bid opening 27.07.2026 at 15:30, which is before the 31.07.2026 submission deadline in Clause 21.1/cover — impossible without amendment.
No other explicit bid-opening calendar date is printed in Clauses 24.x (only procedure).
Until a corrigendum reconciles dates, treat portal critical dates as essential confirmation; document conflict remains unresolved in the pack.
EMD form: online/e-BG only vs original EMD at opening
Clauses 16.1 and IFB require Bid Security only via ONLINE and e-BG, but Clause 24.2 says bids without original EMD/EMD exemption document at opening will be rejected and technical bids not opened.
Practical compliance path stated for bidders is online/e-BG on tntenders.gov.in; the 'original EMD' wording appears residual and creates rejection risk if interpreted literally.
Seek clarification/pre-bid confirmation whether any physical EMD instrument is still expected.
Scheme capacity: 1.00 MLD vs BOQ line '1.10 MLD'
Bid document title/IFB/salient details consistently state 1.00 MLD, but one BOQ item description heading reads PROVIDING 1.10 MLD WATER SUPPLY SCHEME.
BOQ work-name header elsewhere still says 1.00 MLD; treat 1.00 MLD as the scheme requirement unless BOQ quantities clearly implement 1.10 MLD.
Clarify with Employer which capacity governs design/guarantee.
Pumping main length: 27,000 m vs 26.774 km eligibility base
Salient details specify 250 mm OPVC 12.5 KSC pipe 27,000 m, while physical experience criteria use total length 26.774 km for the 30%/higher-dia thresholds.
Difference is about 226 m; eligibility percentages are computed on 26.774 km in the qualification table.
BOQ quantities should be checked item-wise for the payable length; qualification table values are fixed as printed (8.032 km / 1.338 km).
GCC starting page vs Annexure pagination
Index lists General Conditions of Contract from page 69, but pages 61–72 are Annexures I–XII and GCC definitions appear later; use clause titles rather than index page map alone.
Does not change commercial terms but can mislead navigation.
Pre-bid queries
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.
6
Reconcile critical dates on portal vs IFB vs Clause 21.1
Please confirm the final download end date, bid submission deadline and technical/financial bid opening dates/times on https://tntenders.gov.in, given IFB (24/27 Jul 2026) conflicts with cover/Clause 21.1 (submission 31.07.2026 15:00).
Ask whether any corrigendum has been or will be issued to supersede the IFB table.
Confirm holiday-shift rule application if 31.07.2026 is a holiday.
Is any physical/original EMD still required at opening?
Clause 16.1 mandates ONLINE/e-BG only, but Clause 24.2 rejects bids without original EMD at opening — please confirm exclusive online/e-BG compliance and whether any hard-copy instrument or exemption certificate must reach the CE office, and by when.
Also confirm e-BG claim period/validity expectation relative to 120-day bid validity.
Confirm governing scheme capacity 1.00 vs 1.10 MLD and pipeline length base
Please confirm whether the scheme guarantee/design capacity is 1.00 MLD or 1.10 MLD (BOQ heading) and whether payable/qualification pipeline length is 27,000 m or 26.774 km.
Affects design duty of pumps, trial-run acceptance and experience calculation thresholds.
Class I registration — which register is mandatory at bid stage?
IFB eligibility line says Registered Class I Contractors (Civil), while Clause 6 opens to any bidder meeting requirements and Clause 33 allows post-award TWAD registration — please confirm whether non-Class-I or non-TWAD-registered firms can bid if financial/physical criteria are met.
Material pass/fail for many potential bidders and JVs.
Paid maintenance scope, staffing, payment and power/consumables risk
Please detail measurable O&M KPIs for the 12-month paid maintenance, payment schedule/BOQ items for maintenance, mandatory O&M staffing/shifts, and exact split of power, chemicals, spares and major repair costs between Employer and Contractor during Section II and DLP.
Special Conditions put normal O&M power on Employer but construction/trial power on bidder; consumables generally on Contractor unless priced.
Need clarity on whether paid maintenance is a separate priced BOQ component or deemed included.
Land, ROW, river permissions and SIPCOT interface risks
Please confirm status of land acquisition/ROW for the ~27 km pumping main, river-bed infiltration well permissions, road/rail/utility crossings, and SIPCOT boundary interface responsibilities, and whether delays for permissions entitle EOT without LD.
Site data disclaimers place investigation risk on bidder; foreclosure clause pays only for executed works with no profit claim.
Risks
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.
6
Tight construction programme with milestone LD
12-month construction with aggressive cumulative milestones (30/50/70/100%) plus 3-month trial run; LD at 0.05% of unfinished work per week, capped at 10% of contract value, without prejudice to time-bar termination.
LD imposed via multi-step show-cause (15+7+3 days) and can apply automatically if no reply.
Activity Chart must be approved; Employer may reject updates without prejudice to LD.
Defects correction: attend within 3 days of notice or Employer remedies at contractor risk/cost.
High security stack and long post-completion exposures
EMD Rs.9.65 Lakh; performance security 2–5%; staged retention/5% DLP BG for 2 years; optional/forced water-tightness retention or indemnity; additional 5% BG on water-retaining structures for 3 more years after DLP.
Performance security forfeitable on termination for specification/terms failure.
Bid security forfeitable for validity withdrawal or failure to sign/perform security.
Minus bids sharply increase performance security percentage (up to 5%).
Payment cash-flow and withholding risks
Pipe payments heavily back-ended and consignment-linked; 40% bill withholding risk on water-retaining structures unless indemnity given; Employer payment target 6 weeks after bill submission — working capital intensive on ~27 km pipeline.
Subsequent pipe consignments payable only if prior consignments meet laying/testing thresholds (50% of immediately preceding and 100% of earlier).
Interest-bearing mobilisation advance recoverable quickly (20% of certificates after 30% threshold).
Final bill only after maintenance completion.
One-sided termination / foreclosure and broad Employer rights
Employer may terminate for any reason regarded as breach and recover extra completion cost; foreclosure allows stopping whole/part works with no claim for loss of profit—only eligible amount for executed unusable works as certified by Engineer.
Employer may accept/reject any bid and annul process without liability or assigning reasons.
Not bound to accept lowest bid.
Site / utility / power risk allocation
Bidder bears site investigation risk (soil/levels not guaranteed); must handle notices to telephone/railway/electric utilities; construction and trial-run EB power on contractor; multiple river/road crossings likely on long OPVC main.
Penalty up to 10% of defective work value plus rectification at contractor cost.
Price adjustment stops after agreement period except listed force-majeure/land acquisition/design-change EOT cases.
Qualification documentation severity
Pass/fail hinges on Notary-attested EE-rank certificates with highly specific content; private-work proofs are onerous; outside-State certificates may be re-verified; missing credentials can make bid non-responsive with limited clarification time.
If clarification not provided within stipulated time, bid declared non-responsive.
Internal date/EMD contradictions create administrative rejection risk even for compliant online filings.
Contacts
