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.
31
Portal and mode
E-tender only on https://iocletenders.nic.in; offers by any other mode not accepted.
Domestic two-bid system: unpriced techno-commercial documents + online BOQ price bid; prices must not appear in technical bid.
Bidders need Class-3 DSC for new portal mapping (existing Class-2 continues till expiry).
Reverse Auction applicable after techno-commercial qualification (Annexure-RA).
Signing and physical originals
Declarations/undertakings to be sealed and signed or digitally signed; authorization for tender signatory mandatory; physical original EMD BG (if used) to tender issuing authority within the prescribed window.
Non-submission/partial submission of filled Declarations and Undertakings may lead to rejection without further communication.
Tender Acceptance Format on company letterhead by authorized representative; scanned upload.
Physical EMD instrument envelope super-scribed with tender details / Offline EMD as specified; postal delay is bidder’s risk.
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 in tender pack
The downloaded tender document set contains no corrigendum or addendum files; original NIT/SCC/GCC/BOQ values apply as issued.
Document list comprises NIT, Declarations, SCC-Technical, SCC-Commercial, GCC/HSE, Annexure-SP, BOQ and standard portal help files only.
NIT advises bidders to visit the portal for official version including any future corrigendum/amendment, which would then be binding.
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.
4
Completion period: 15 vs Eighteen months
Both NIT and SCC-Technical state “15 (Eighteen) months”, so the numeral and words conflict; bidder should seek written clarification before relying on either figure.
Same conflicting phrase appears in NIT Sl. No. 4 and SCC-Technical Cl. 57.
No corrigendum resolves the conflict.
EMD BG validity wording
NIT requires EMD BG validity of 07 months from last bid-submission date, while SCC-Commercial requires BG validity at least 3 months beyond bid validity (bid validity is 6 months from tender opening).
NIT Cl. 24.i states NIT provisions supersede all other sections of the tender document, so NIT’s 7-month-from-submission rule should be followed, but bidders should ensure the instrument also satisfies the SCC “3 months beyond bid validity” construct if opening is delayed.
Splittable job vs “indivisible / single successful bidder” boilerplate
NIT Cl. 23.c and Annexure-SP make the job splitable 60:40 to two agencies, while NIT Cl. 24.vi states the subject work is indivisible and awarded to a single successful bidder unless stated otherwise.
Because Cl. 23.c / Annexure-SP expressly state otherwise, the splitable regime applies; Cl. 24.vi is residual boilerplate.
Sub-contracting not permitted vs mechanical-contractor agreement for PQC
NIT Cl. 23.j says Sub-Contracting is Not permitted, yet NIT Cl. 12 allows an agreement with a mechanical contractor to meet additional mechanical experience PQC.
Bidders should clarify whether post-award subcontracting is fully barred and how a pre-bid mechanical-contractor agreement interfaces with execution.
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.
5
Confirm completion period: 15 or 18 months?
Ask IOCL to correct/confirm whether contractual completion is 15 months or 18 months, because both NIT and SCC-Technical print “15 (Eighteen) months”.
Material to resource loading, cash flow, LD exposure and programme.
Mechanical partner vs ban on subcontracting
Seek confirmation whether an agreement with a mechanical contractor for PQC credentials is only for qualification, or whether that party may execute mechanical works despite NIT’s “Sub-Contracting Not permitted”.
If subcontracting is fully barred, pure civil bidders relying on Cl.12 agreements face post-award execution risk.
Free-issue mechanical materials and interface risk
Ask for the free-issue material list, delivery schedule from Dumad Stores, and responsibility for shortages/delays, since mechanical scope depends on Owner-supplied pipes/equipment.
Drawings are stated to be issued post-award; request preliminary MTOs/layouts before bid if available.
EMD BG validity and physical receipt timeline
Confirm which EMD BG validity rule prevails (7 months from bid due date vs 3 months beyond bid validity) and whether original BG must arrive by submission deadline or within 7 days/working days of techno-commercial opening.
NIT and SCC-Commercial timelines differ slightly (7 days vs 7 working days).
Split award PQC and reverse-auction matching
Clarify evaluation when only one bidder can take 70%/60% under Annexure-SP, and the exact consent-letter timelines/email process for L2+ matching after RA.
Material to bid/no-bid if bidder can only resource one lot.
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
Price adjustment (delay discount) up to 5%
Delay beyond scheduled mechanical/final completion attracts stepped price discounts rising to a maximum of 5% of Total Contract Value under GCC Cl. 4.4.0.0.
Discount schedule starts at 1/8% within 1 week late and reaches 5% by 13 weeks; cap is 5%.
NIT marks non-negotiable acceptance of GCC price adjustment for delay.
High security retention and cash-flow drag
10% SD (2.5% ISD + 10% bill retention until SD filled) plus water 1% and power 0.5% deductions materially reduce running-bill cash flow on a ~Rs.61 Cr works package.
No mobilization advance.
Defect Liability Period is 12 months from Completion Certificate; 5% SD retained for DLP obligations.
Quantity-variation / no-compensation clause
SCC-Technical Cl. 34 supersedes GCC 2.6.0.0: payment only for actual executed permanent-work quantities; no compensation for quantity or overall-value deviations.
Mechanical section also states no compensation for quantity reduction and post-award drawings.
Live-refinery site, multi-gang urgency and dewatering risk
Work is inside Dumad Complex hydrocarbon facilities with distributed locations, possible subsoil water, temporary boundary-wall barricading for security, and EIC-driven multi-gang mobilisation—execution risk and HSE exposure are high.
All dewatering, strutting/shoring and temporary barricading at contractor cost.
Job classified Critical; safety penalties in commercial SCC include large per-fatality penalties.
EMD / authenticity / holiday-list exposure
Works-contract EMD of Rs.9.25 Lakh is non-exempt for MSE; forged or incomplete PQC documents can cause rejection, EMD forfeiture and holiday listing; IOCL may verify with clients.
Reverse Auction and split matching create additional commercial pressure after technical qualification.
Local-content / DMISP penalty risk
PPP-MII and DMISP apply; failure to meet declared local content can attract up to 10% of contract value penalty and hold-back of last 10% until CA certificate.
