• Flexible pavement maintenance schedule also appears in 14.1(i)(a) (generic highway rates).
• Bonus clause text appears after a 'Deleted' heading but still sets out 0.03%/day up to 5%.

General bidder eligibility and nationality / security filter

Open to eligible contractors under National Competitive Bidding; foreign ownership/control ≥50% in L-1 is subject to competent-authority approval on national security/public interest grounds.

• Bidders from countries sharing a land border with India are eligible only if registered with the Competent Authority under Public Procurement Order F.No.6/18/2019-PPD dated 23.07.2020; Appendix-IX compliance certificate required.
• Registration must be valid at bid submission and bid acceptance.

BID Capacity

Available BID capacity must be more than total BID value (Estimated Project Cost under Cl. 1.1.1). Formula: Assessed Available BID capacity = (A × N × 2.5 − B + C).

• N = number of years prescribed for completion; A = max value of civil engineering works (excl. bonus) in any one of last five years (updated); B = value of existing commitments/ongoing works to be completed during the project period (LOA-issued but Appointed Date not declared works excluded from B); C = bonus received in EPC projects in last 5 years (updated).
• Updation factors Year-1 to Year-5: 1.00, 1.05, 1.10, 1.15, 1.20.
• Commitments statement must be countersigned by Client/EIC ≥ EE rank (or Concessionaire/SPV for BOT) and verified by Statutory Auditor; format Annexure-VI of Appendix-IA.

Technical Capacity and similar works

Over past 5 financial years preceding Bid Due Date, payments received / self-construction on Eligible Projects (adjusted) must exceed Threshold Technical Capacity of Rs. 22.95 Crore; plus similar completed works threshold.

• Similar completed works (normal Highway projects including Major Bridges/ROB/Flyovers/Tunnels pathway): either (i) two similar completed works each ≥ Rs. 5.73 Cr (25% of EPC), OR (ii) one similar completed work ≥ Rs. 6.88 Cr (35% of EPC), from Eligible Projects in Category 1 and/or 3; client certificates required.
• Eligible projects for similar work expressly include: Slope Protection and landslide restoration works (Height of Slope not less than 15m) on Highways (NH/SH/Expressways etc).
• Similar completed work must comprise all major components similar to the invited work; Experience Certificate format Annexure-IX of Appendix-IA plus Statutory Auditor/Client certificate as in Annex-IV; NHAI projects’ Experience Certificate to be issued by concerned GM(T) at NHAI HQ/Project Director.
• Subcontracting/JV claimed projects need government authority/Client approval restricted to allowable subcontracting limit/JV share.
• Category factors: highways PPP/construction factor 1; core sector 0.75; OECD developed-country projects further ×0.5.
• For Categories 3 & 4, receipts/work executed < Rs. 1.14 Cr not reckoned; maintenance-type nomenclatures generally not eligible (with stated exceptions).
• BIMS upload of experience is required; details taken from BIMS.

Financial Capacity — Net Worth and Turnover

Minimum Net Worth Rs. 1.14 Crore at close of preceding financial year; minimum Average Annual Turnover Rs. 6.88 Crore (updated) for last 5 financial years.

• Turnover updation factors Year-1 to Year-5: 1.00, 1.05, 1.10, 1.15, 1.20.
• Audited Annual Reports for last 5 years required; Statutory Auditor net-worth certificate required (methodology per Cl. 2.2.2.9(ii)).
• Net Worth definition: paid-up share capital + reserves from profits and securities premium, less accumulated losses, deferred expenditure and miscellaneous expenditure not written off; excludes revaluation reserves, write-back of depreciation and amalgamation.

Joint Venture rules (and 100 Cr bar)

Clause 2.1.11 sets JV rules (max 3 members; Lead ≥60% of Bid/Technical/Financial Capacity; other members ≥20% each; each member min 26% equity; Lead performs ≥51% of total Project Highway length; joint and several liability till DLP; JBA Appendix-V). Separately, Cl. 2.1.11(h) bars JV up to Estimated Project Cost of Rs. 100 crores, except for maintenance works on EPC mode.

• This project’s Estimated Project Cost is Rs. 22.95 Cr (< Rs. 100 Cr) and is described as slope protection/landslide restoration construction on EPC with a maintenance/DLP period — not clearly labelled as 'maintenance works to be taken up on EPC mode'. Whether JV is permitted is a material open point (see Pre-bid Queries and Contradictions).
• If JV allowed: for similar work Cl. 2.2.2.2(ii), one similar work of 35% or two of 25% each (or the JV clause’s 'one similar work of 20%' wording) must be completed individually by any JV member from Category 1 and/or 3 — wording itself needs clarification.

Debarment / non-performer / Conflict of Interest

Only firms neither debarred on tender opening date nor debarred on LOA date are considered; debarred/non-performer bids are ignored. Conflict of Interest disqualifies and can forfeit Bid/Performance Security.

• Non-performer triggers include missed milestones with progress not commensurate even after 6 months from milestone/SCD (unless EOT for Authority default/Force Majeure), failure to mobilize key equipment within 1 month of Appointed Date, repeated NCR failures, etc.
• Bidder/JV member expelled or terminated leading to debarment after hearing is ineligible as set out in Cl. 2.2.1.
• Conflict of Interest covers common controlling shareholders (>5% tests), common constituents, cross-subsidies, same legal representative, information-access relationships, and consultant participation in preparation of project documents.

Make in India / Class-I local supplier preference

Class-I local supplier needs minimum 50% local content; Class-II minimum 20%. Purchase preference margin for Class-I is 20% against L1. Self-certification of local content mandatory with technical bid; for procurement > Rs. 10 crore, statutory auditor/cost accountant certificate of % local content required.

• If L1 is not Class-I, lowest Class-I within 20% margin is invited to match L1; else award to L1.
• Missing self-certification → treated as Non-Local Supplier.

Project identity, mode and location

EPC contract for slope protection measures and landslide restoration of hill slopes on Bogda-Sada section of NH-566 in Goa; project length stated as 0.99 Km; Authority is NHAI RO Mumbai.

• NIT/RFP title matches; Site is parts of NH-566 (Old NH-17B) corridor serving port/airport traffic in Goa.
• Scope of Project under EPC Art. 2.1: construction per Schedules A–D, maintenance per Schedule-E, and all incidental obligations.

Work stretches and nature of protection works

Landslide restoration and slope protection/stabilization at five locations on NH-566, with Gabion fascia, nailing/anchors and drainage as minimum scope.

• Locations (Schedule-B / Schedule-A ROW table): (i) Ch 12+700–12+800 RHS, 100 m; (ii) Ch 13+100–13+250 RHS, 150 m; (iii) Ch 13+860–14+080 BHS, 240 m (table later shows 220 m for nailing with gabion — minor internal length variance); (iv) Ch 16+130–16+370 RHS, 240 m; (v) Ch 16+470–16+750 RHS, 280 m.
• Proposed slope protection: Gabion fascia as per IS 16014:2024 with Nails (SDA/CTA) and anchor trench cum drain, perforated PVC pipe, scaling of loose rock and removal of vegetation/bushes/shrubs/hanging loose rock mass.
• Components include HAR polymer-coated fascia gabion units suitable for C4 environment, H-frames connecting gabions with anchors, 50 mm dia PVC perforated subsurface drains wrapped with non-woven geotextile taken deep behind soil-nail zone; surface nails over entire slope with length/spacing/diameter from detailed investigation during construction.
• Contractor must prepare detailed design & drawings (cross-sections with gabion fascia, drain, soil nailing, self-drilling anchors etc.) after field investigations; design vetted from recognized/reputed government institution; Schedule-B provisions cannot be reduced — only design of components is for AE approval.
• Start/end chainages and heights may vary with site conditions without constituting Change of Scope.
• ROW at work locations stated as 45 m.

Completion period, milestones and maintenance/DLP

Construction Period 6 Months; Scheduled Completion Date is the 180th day from Appointed Date. Maintenance/Defects Liability for this slope-protection project is 5 years from Completion Certificate (project-specific clauses).

• Milestones (Schedule-J): MS-I day 63 — ≥10% Contract Price stage payments; MS-II day 108 — ≥35%; MS-III day 153 — ≥70%; SCD day 180 — full completion.
• NIT: Completion period 6 Months; Maintenance period 5 years.
• RFP Cl. 1.1.2: Defect Liability Period shall be 5 years.
• EPC Cl. 17.1(h): 5 years DLP for Slope protection measures and landslide restoration of hill slope; but Cl. 17.1(d) also lists 10 years for stand-alone Slope Protection works (see Contradictions).
• Contractor maintains existing highway traffic-worthiness during Construction Period at its cost (Cl. 10.4).
• Designs/drawings to be approved by Authority’s Engineer within 90 days from Appointed Date.

Standards, design responsibility and notable exclusions/constraints

Works to conform to Specifications and Standards in Schedule-D and applicable IRC/MoRTH standards; Contractor designs and constructs; Schedule-B minimum requirements cannot be reduced via design.

• Feasibility/DPR is preliminary only; Bidder must do own surveys/investigations; no claim for inadequacy of Bidding Documents (RFP 2.5).
• Change of Scope aggregate cap generally 10% of Contract Price (Art. 13).
• Authority to provide ≥90% ROW of Construction Zone within 30 days of Agreement (contiguous stretches not less than 5 km — a standard-form provision poorly matched to 0.99 km slope sites).
• Selected Bidder must use NHAI Data Lake Portal for contractual correspondence; no physical documents unless RFP/legal requirement.

Submission mode and portal

Single-stage two-part e-tender on CPPP/e-procurement portal https://etenders.gov.in (also referenced as http://etenders.gov.in). Technical Bid and Financial Bid uploaded online; only online bids are evaluated.

• Registration on e-tenders portal must be valid at least up to bid submission date.
• Upload technical documents listed in Cl. 2.11.1 as separate PDF/RAR files ≤30 MB each.
• Financial Bid (Appendix-IB / percentage quote) submitted online only.

Online bid must be submitted using the digital signature of the Bidder’s authorized representative. Hard-copy BID content is to be typed and signed in indelible blue ink by the authorized signatory; alterations initialled.

• Class of DSC is not expressly specified beyond use of digital signature on the e-procurement portal.

Physical originals — who, what, when, where

Core originals (Bid Security, PoAs, JBA, Integrity Pact, foreign apostilled experience certificates, etc.) are required physically from the Lowest Bidder before LOA under Cl. 2.10.1/2.11.2/2.12; DD/FDR/Banker's Cheque Bid Security must reach within 5 working days of Bid Due Date (11:00 hrs). Conflicting clauses also condition technical opening on physical receipt of Cl. 2.11.2 documents — treat as a critical ambiguity (see Contradictions).

• Physical envelope identification: project name; bidder name/address; BID Due Date on top-right corner.
• Addressed to CGM (Tech)/RO Mumbai, T-341, 4th Floor, Tower 8, BRSCCL, Sector-11, CBD-Belapur, Navi Mumbai-400614.
• L1 failure to submit originals → unconditional debarment from NHAI projects for 5 years (Cl. 2.10.1).
• If L1 fails to submit originals required under 2.11.2, Authority annuls process and invites fresh BIDs (Cl. 1.2.7).

Envelope structure for physical submission

Documents listed at Cl. 2.11.2 go in one sealed envelope bearing the full project identification title and bidder particulars.

No corrigendum/addendum in the tender pack

The downloaded tender documents contain no corrigendum or addendum file; tender-metadata also lists an empty corrigenda array. All dates, amounts and conditions above are as originally issued in the NIT/RFP/EPC pack dated August 2026.

• Documents present: Tendernotice_1.pdf, NIT.pdf, RFP Goa Slope Protection.pdf, Revised EPC agreement Schedule Sada Bogda R-2.pdf, Financial Proposal.xls.
• Bidders should still monitor https://etenders.gov.in / NHAI portal for any later addenda before Bid Due Date (Cl. 2.9).

Values that finally apply (no amendments)

Finally applicable key values: Bid Due Date 10.09.2026 15:00 IST; Tech opening 11.09.2026 16:00 IST; Bid validity 120 days; Estimated cost Rs. 22.95 Cr excl. GST; Bid Security Rs. 22.95 Lakh; Bid fee Rs. 10,000; Completion 6 months/180 days; DLP/Maintenance 5 years (project-specific); PS 5% of Bid Price.

Physical submission timing — L1 before LOA vs all bidders before technical opening

Multiple clauses say originals under Cl. 2.11.2 are submitted by the Lowest Bidder before LOA, while Cl. 3.1.1 (and parts of 2.13) require those physical documents before Technical Bid opening/consideration.

• L1-before-LOA line: Cl. 2.10.1, 2.11.2, 2.11.4, 2.12, and 1.2.7.
• All-bidders/pre-opening line: Cl. 3.1.1 ('Technical BID of only those Bidders shall be online opened whose documents listed at clause 2.11.2 ... have been received physically'); Cl. 2.13 (physical receipt after Bid Due Date time rejected); responsiveness Cl. 3.1.6.1(b).
• DD/FDR/Banker's Cheque Bid Security still has a hard 5-working-day post-BDD physical deadline for bidders using those instruments.
• Action: seek written clarification; safest conservative path is to be ready to deliver the full Cl. 2.11.2 physical set immediately after Bid Due Date unless Authority confirms L1-only.

Whether Joint Venture is allowed (Rs. 100 Cr bar vs full JV machinery)

Cl. 2.1.11(h) prohibits JV up to Estimated Project Cost of Rs. 100 crores except for maintenance works on EPC mode, while the RFP elsewhere fully elaborates JV bidding (capacity splits, PoA, JBA) and this project’s cost is only Rs. 22.95 Cr.

• Project is construction of slope protection/landslide restoration with a 5-year maintenance/DLP — not clearly 'maintenance works like PR/HIPR on EPC'.
• If 2.1.11(h) prevails, sole bidding only; if maintenance exception is stretched to this work, full JV rules apply.
• Also internal JV similar-work wording mixes 'one similar work of 20%' with '35% / two×25%' tests (Cl. 2.2.2.4(ii)).

Defects Liability / Maintenance duration — 5 years vs 10 years

Project-specific texts (NIT, RFP 1.1.2, EPC 17.1(h), 14.1(i)(e)) state 5 years for this slope-protection work, while EPC 17.1(d) and 14.1(i)(d) generic stand-alone slope-protection rows state 10-year DLP/maintenance structures.

• More specific project clauses and NIT/RFP point to 5 years; bidders should still get Authority confirmation because PS validity is tied to DLP (PS until 60 days after DLP).
• Maintenance payment also conflicts: 14.1(i)(e) gives a single 3.75% of contract Amount for 5-year post-construction period; 14.1(i)(d) gives 0.25%/yr for first five years and 0.50%/yr for next five.

Agreement signing deadline after 50% Performance Security — 10 days vs 5 days

Schedule of Bidding Process requires signing within 10 days of receipt of 50% PS/APS, while Cl. 2.22 requires execution within 5 days of receipt of 50% PS/APS.

• Both cannot be simultaneously true; seek clarification or plan for the shorter 5-day timeline.

Bid Security form list vs Cl. 2.11.2(g) 'Original Bank Guarantee' only

Cl. 1.2.4/2.20.1 allow Insurance Surety Bond, DD, FDR, Banker's Cheque or BG, but Cl. 2.11.2(g) physical list states 'Original Bank Guarantee' only.

• Practical reading: any permitted instrument under 2.20 is acceptable, with physical handling rules differing by instrument type; confirm if using non-BG forms.

Schedule-B length for Ch 13+860–14+080 — 240 m vs 220 m

Description of project states BHS length 240 m for Ch 13+860–14+080, while the slope-protection features table lists 220 m for the same chainage.

• Notes allow start/end variation without Change of Scope; still a drafting inconsistency to clarify for pricing/quantity risk.

Draft Contract Price figure in EPC Art. 19.1 vs Estimated Project Cost

EPC Cl. 19.1 shows a placeholder Contract Price 'INR . xxxxxxx (Inclusive. GST) (INR Twenty-Seven Crore Thirty-One Lakhs Five Thousand Only)' while NIT/RFP Estimated Project Cost is Rs. 22.95 Cr excluding GST.

• Contract Price is the accepted Bid Price (lump sum), not the estimate; the Rs. 27.31 Cr figure appears to be a residual/template fill and should not be treated as the official estimate.
• Financial Proposal and NIT control the estimate at Rs. 22,95,00,000 excl. GST.

Confirm whether JV is permitted for this Rs. 22.95 Cr works tender

Ask Authority to expressly confirm if Cl. 2.1.11(h) bars JV for this project or if the 'maintenance works on EPC mode' exception applies to slope protection/landslide restoration.

• Impact: bid/no-bid structure, consortium formation, and which capacity tests apply.
• If JV allowed, also clarify Cl. 2.2.2.4(ii) similar-work percentages (20% vs 35%/2×25%) and how '51% of total length of the Project Highway' applies to discrete slope sites.

Clarify physical document submission deadline for all bidders vs L1 only

Request a single ruling reconciling Cl. 2.10.1/2.11.2/2.12 (L1 before LOA) with Cl. 3.1.1/3.1.6.1(b)/2.13 (physical docs needed for technical opening/responsiveness).

• Also confirm exact list and timing when Bid Security is BG/e-BG/Surety Bond versus DD/FDR/Banker's Cheque.
• Impact: pass/fail responsiveness and logistics of originals to RO Mumbai.

Confirm governing DLP and maintenance payment regime (5 years / 3.75% vs 10 years / 0.25–0.50%)

Ask which of EPC 17.1(d)/(h) and 14.1(i)(d)/(e) govern this contract, and how Performance Security validity and maintenance billing will be applied.

• Impact: long-term bond cost, cash flow, and pricing of post-construction obligations.

Design-fix / geotech / quantity risk on nail length, height and chainage limits

Seek clarity on baseline geotechnical data availability, whether Schedule-B gabion+nail scheme is mandatory minimum even if design supports lesser works, and pricing risk where nail length/spacing/diameter and protection height are fixed only after construction-stage investigation with no CoS for start/end/height variation.

• Also reconcile 240 m vs 220 m for Ch 13+860–14+080 and confirm payable measurement basis under Schedule-H for these items.
• Impact: major EPC pricing and execution risk on active landslide slopes beside live NH-566 traffic.

ROW handover practicality and Authority damages cap

Standard Cl. 3.1 promises ≥90% Construction Zone ROW within 30 days in ≥5 km contiguous stretches — mismatched to ~1 km fragmented slope sites. Confirm actual vacant possession dates for each chainage and interaction with monsoon/working-season constraints in Goa hills.

• Also note aggregate Authority Damages under 3.1/8.3/9.5 capped at 1% of Contract Price — limited relief if site access is delayed.

Agreement signing period after 50% PS — 5 or 10 days?

Ask Authority to confirm whether Cl. 2.22 (5 days) or Schedule 1.3 item 15 (10 days) controls signing of Agreement after receipt of 50% PS/APS.

Very tight 6-month / 180-day construction window on active hill slopes

Scheduled Completion is only 180 days from Appointed Date with intermediate milestones at days 63/108/153; monsoon and traffic management on NH-566 can erode the window quickly.

• Delay Damages: 0.05% of Contract Price per day after 30 days’ slip from milestone/SCD dates, capped at 10% of Contract Price; exceeding 10% is incurable default enabling termination (Cl. 10.3).
• Designs/drawings must be AE-approved within 90 days of Appointed Date — consumes half the construction period before full-pace execution.
• Early-completion bonus exists (0.03%/day, max 5%) but is secondary to LD exposure.

EPC design/quantity risk on nails, height and gabion scheme

Nail geometry and protection height are investigation-dependent during construction, yet Schedule-B minimum scheme cannot be reduced and chainage/height variations are excluded from Change of Scope.

• Contractor bears unforeseen difficulties risk under standard EPC sufficiency-of-price clauses.
• Design must be vetted by recognized government institution — time and third-party dependency.
• Live traffic and scaling of loose boulders create high HSE exposure.

Security stack and cash lock-up

Bid Security Rs. 22.95 Lakh (180-day instrument), Performance Security 5% of Bid Price (valid to DLP+60 days), possible APS for deep discounts, 6% retention up to 5%, and interest-bearing advances at Bank Rate+3%.

• Deep discount below 15% of estimate triggers APS = (% below − 15%) × Bid Price — material capital lock if bidding aggressively.
• Failure to furnish full PS/APS even after paid 60-day extension cancels award and forfeits Bid Security.
• L1 failure to submit physical originals → 5-year NHAI debarment.

Long post-construction liability and maintenance performance

Even under the 5-year project-specific DLP, contractor must remedy defects within 15 days (or AE-set period) at own cost; failure allows Authority execution plus 20% Damages on cost.

• If 10-year stand-alone clauses were applied, bond and maintenance exposure would double — unresolved contradiction increases uncertainty.
• APS release conditions include PCI/IRI NSV surveys with 5% APS penalty per failure — metrics oriented to pavement, awkward fit for pure slope works.
• Maintenance obligations include traffic safety, routine repairs and conformity with Schedule-E.

One-sided / limited Authority liability and site-delay relief

Authority Damages for ROW/other specified delays are capped at 1% of Contract Price aggregate; Contractor cannot claim for Bidding Document inadequacies; Authority may withdraw works up to 10% value with Contract Price reduced to 90% of withdrawn value (higher bands above Rs. 100 Cr).

• Deemed withdrawal after 180 days without clearances/ROW in certain areas without counting toward the 10% cap.
• Authority may reject any bid / annul process without liability (Cl. 2.16).

Traffic maintenance during construction on port/airport corridor

Contractor must keep existing NH-566 traffic-worthy and safe during Construction Period at its own cost; Authority may execute maintenance at contractor’s risk and cost on default.

• Corridor carries port and Dabolim airport traffic; diversions need AE prior written approval.
