Bid validity

Bid validity is 120 days from the last/date of submission of bid.

• Withdrawal or modification of terms before validity ends allows full EMD forfeiture.

Contract study durations (as printed)

NIT states Part A 5 months and Part B 3 months; deliverable table is 20 weeks (Part A) and 12 weeks (Part B); scope clause 7 instead states Part A 8 months and Part B 4 months — treat as internal conflict (see contradictions).

• Part B may commence only after successful completion of Part A and MADC approval.
• Agreement to be signed within 15 days of LOA.

Tender / estimated value

No estimated tender cost or fixed consultancy fee is published; bidders quote lump-sum Part-A and Part-B fees in BOQ.xls (exclusive of GST).

• EMD must cover bid validity period; successful bidder’s EMD adjusted against/returned after Security Deposit.
• Unsuccessful technical-stage EMD auto-refunded via portal; other non-L1 refunds after award within reasonable time.
• MSE concessions for EMD as per prevailing law/orders.

Security Deposit / performance security

Security Deposit is 5% of consultancy fees quoted, payable by selected consultant as DD within 15 days of LOA; released after successful completion.

• Payment schedule note also requires SD in form of BG before first payment release — DD vs BG conflict (see contradictions).
• SD may be Insurance Surety Bond/Guarantee Bond; if issuer cannot pay, consultant must top up.
• MADC may invoke SD and ‘Performance security’ on 15 days’ notice for breach or LD recovery.
• On determination/rescission, full SD and performance Surety Bond/BG are at MADC’s absolute disposal.

Corrigendum 1 (Other) — Pre-bid VC link only

Published material titled ‘VC link for prebid meeting’ supplies Webex join details for the already scheduled 17 Aug 2026 11:00 AM IST pre-bid; it does not amend fees, EMD, eligibility, scope or bid deadlines.

• Original: Pre-bid meeting 17.08.2026 at 11.00 hrs (CRITICAL DATA SHEET).
• Amended/added: Meeting link https://madcindia1.webex.com/... ; meeting number 2514 653 9857; password 1100; duration 1 hr 30 mins.
• Impact: Enables remote participation; no change to bid submission end 02.09.2026 15.00 hrs or other commercial terms.
• Bidder action: Join via the issued Webex credentials; still use portal Seek Clarification on/before pre-bid as required.

Values that finally apply after all corrigenda

All substantive commercial and eligibility terms remain as in the original tender/NIT; only pre-bid access mode was supplemented by VC details.

• Publishing/sale start: 30.07.2026 (from 13.00 hrs).
• Pre-bid: 17.08.2026 11.00 hrs via Webex (Corrigendum 1 link).
• Bid submission: 20.08.2026 13.00 hrs to 02.09.2026 15.00 hrs.
• EMD Rs 50,00,000; tender fee Rs 50,000 + 18% GST; bid validity 120 days.
• No date-extension chain beyond the single original schedule.

Study duration: NIT/deliverables vs Scope clause 7

NIT and payment timeline imply Part A ≈5 months (20 weeks) and Part B ≈3 months (12 weeks), but Scope ‘Study duration’ states Part A 8 months and Part B 4 months.

• NIT Clause 3: Part A – 5 months; Part B – 3 months.
• Deliverables table: Part A final at 20 weeks; Part B final at 12 weeks.
• Scope Clause 7: Part A Eight (8) months; Part B Four (4) months.
• Prevail for bidding schedule risk: treat as unresolved — seek pre-bid clarification; LD is tied to ‘Scheduled stages’, so the weekly deliverable schedule is the practical exposure unless MADC amends.

Award basis: ‘lowest bid’ wording vs QCBS marking

Clause 8.6 says contract normally awarded to lowest evaluated bid, while Clauses 15–17 define 80 technical + 20 financial QCBS with preferred bidder as highest total marks.

• More specific evaluation Clauses 15–17 and marking table should guide bid strategy (QCBS), but 8.6 creates interpretive risk — clarify at pre-bid.

Security Deposit instrument: DD vs BG

SCC Clause 2 requires SD 5% as DD within 15 days of LOA, while payment Note (f) requires SD in form of BG before first payment.

• Also allows Insurance Surety Bond/Guarantee Bond language elsewhere.
• Bidder should confirm acceptable instrument(s) and whether EMD conversion/return timing aligns.

EMD acceptable forms: online / DD / BG

Clause 5 states online EMD and that bidders may have to submit DD, while Appendix-A and Envelope-I procedures provide for Nationalized-bank BG offline; Note (2) forbids ‘any other form except mentioned above’.

• Practical reading: online portal payment is primary; BG offline path is detailed with physical submission rules; DD is mentioned without a full procedure — confirm on portal/pre-bid which offline instruments are live.

Bid opening date missing from CRITICAL DATA SHEET

Clause 12 repeatedly opens Envelope-I/II on CRITICAL DATA SHEET date/time, but the printed CRITICAL DATA SHEET ends at Bid Submission End Date with no opening fields.

• Bidders must watch mahatenders.gov.in notices for actual opening schedule.

Index page count vs PDF annexures set

Index lists Annexures I(a)–VII on pages 70–85 and total 86 pages, but the issued PDF ends at page 76 with only Annexures I(a), I(b), II, III, IV plus price schedule/location plan — Annexures V–VII (and a full BG proforma body) are not present.

• Creates format gap for any documents that would have lived in missing annexures.

Confirm controlling study duration and LD baseline

Please confirm whether contractual duration is Part A 5 months / Part B 3 months (NIT & 20/12-week payment stages) or Part A 8 / Part B 4 months (Scope clause 7), and which dates trigger compensation for delay.

• Material to resourcing, price, and 1%/week stage LD exposure capped at 10%.

Own-cost alternative-site Pre-FS risk allocation

Clarify triggers, geographic limits, and whether ‘own cost’ alternative-site Pre-Feasibility + OLS if Kore site is not approved is unlimited, and if time extension without cost is granted for that contingency.

• This is open-ended contingent scope that can erase the entire fee economics.

EMD and SD instrument matrix

Confirm currently accepted EMD modes (online only vs DD vs Nationalized BG) and whether post-award SD must be DD, BG, and/or Insurance Surety Bond, including exact validity/claim wording.

• Also confirm whether CRITICAL DATA SHEET physical-BG deadline equals bid submission end (no separate BG receipt time is printed).

QCBS vs L1 award rule

Confirm that Clauses 15–17 (80:20 QCBS, highest total marks) override Clause 8.6 ‘lowest evaluated bid’ language for final selection.

• Affects pricing strategy versus technical score investment.

Approvals within fixed Part A fee and timeline

Final TEFS payment (35% of Part A) is linked to ‘obtaining all approvals’; please list which clearances are mandatory for that milestone vs best-efforts, and treatment of MoEF/public-hearing delays beyond consultant control.

• Also clarify which marine/EIA studies must be by ‘Government Institute of National repute’ and whether those costs are fully inside the lump sum.

Missing annexures V–VII and BG format

Index references Annexures I(a)–VII through page 85, but PDF stops earlier; please issue missing formats (especially full EMD/SD BG proforma and any Annexures V–VII).

• Without prescribed BG text, banks may delay instrument issuance before 02.09.2026.

Unlimited alternative-site rework at consultant cost

If Kore/Vadhavan site is not approved by any authority for any reason, consultant must redo Pre-FS + OLS for an alternative site at own cost with no extra fee to MADC.

• High commercial tail risk for a multi-clearance offshore airport site.

Delay LD and payment hold rights

Compensation for delay 1% of stage fee per week (or lesser as decided), cumulative cap 10% of total consultancy fees; MADC may suspend all payments on 30-day cure notice and invoke SD/performance security on 15 days’ notice.

• No extra fee for time extensions even when delay is beyond consultant control.
• Significant deficiencies can attract quantified damages and withholding from on-account bills at MADC’s discretion.

Approvals-linked payment and open-ended surveys

Large Part-A fee tranches depend on MADC acceptance and ‘obtaining all approvals’; additional surveys during DPR/approvals are at consultant’s own cost with no claim.

• India travel/follow-up for approvals is non-reimbursable and must be inside lump sum.

Embedded costly obligations (training, roadshows, facilities)

Lump sum must fund one-week overseas training for 5 MADC staff at an international offshore airport, ≥4 international roadshows with 5 officials’ travel, specified premium laptop, and Mumbai project office + HO monitoring cell for full consultancy duration.

• Team Leader change penalty Rs 1 lakh/month amplifies key-person risk.

Conflict lock-out from downstream project works

Successful consultant and affiliates are disqualified from later construction goods/works/services on the same project; consultant/sub-consultants also barred from associating with the execution contractor on related MADC works.

• Strategic opportunity cost for full-service infrastructure groups.

Termination, forfeiture and liability posture

On determination/rescission MADC may take full SD and performance bond absolutely; wrong tender information can forfeit entire EMD and debar for 2 years; contractual financial liability capped at contract value but professional indemnity must equal contract value for contract period + 3 years after physical completion.

• Arbitration in Mumbai; for claims ≤ Rs 10 Cr sole arbitrator appointed by VC&MD MADC (appointing-authority asymmetry).

High eligibility bar and QCBS presentation risk

Rs 500 Cr average consultancy turnover and Code E Greenfield TEFS/DPR in 7 years plus offshore-experienced marine expert sharply limit the field; 20-mark presentation and 70% overall technical threshold create rejection risk even for eligible firms.

• EMD of Rs 50 lakh is large relative to pure consultancy contests and is cash/BG locked through evaluation.
