If already executing MES works totaling more than twice the tendering limit of the eligible class, ineligible. After securing two MES works must get registered in appropriate class or become ineligible for further participation.

Work cannot be executed by subletting or POA to a third party/another firm; limited POA only to sons/daughters/spouse of proprietor/partner/director or firm's own employees/director/project manager, provided they do not have a separate MES-enlisted firm.
Appendix 'A' states Technical PQC criteria as NA (not applicable) beyond the enlistment/class criteria above.
What is being procured: the work, supplies or services, deliverables and quantities, locations, phases, completion or delivery timelines, applicable standards, and notable exclusions.
Lump-sum MES works contract: Provision of DG sets and electrical accessories for Data Centre facility at CABS Bangalore (CA No. CERD/BAN/TOKEN/05 OF 2026-2027). Buildings/services as shown on site plan; executing agency GE(I) R&D (East) Bangalore.
Based on IAFW-2159 (lump sum) and IAFW-2249 GCC, drawings and specifications. Schedule 'A' Parts I–X: buildings/structures; B/R for data centre; 2 cover sheds; excavation/earthwork; internal electrification; internal water supply; road/path/culvert/hardstanding; sewage disposal; external electrification; and market-rate BoQ Part X. Parts II–IX largely percentage-above/below prepriced MES amounts; Parts I & X contractor-quoted rates.
MES-inserted prepriced lump sums carried to BoQ: Part II ₹16,19,282.95; Part III ₹20,87,349.10; Part IV ₹42,173.13; Part V ₹10,65,969.00; Part VI ₹33,783.45; Part VII ₹5,00,073.51; Part VIII ₹1,18,847.22; Part IX ₹9,47,499.00. Bidder quotes % above/below each.
Market-rate Part X (items ~10–71) includes among others: 4 Nos 160 kVA/128 kW silent DG sets (CPCB IV+ or better, 415 V, 1500 RPM, 0.8 pf, 0.85 LF) with foundation, testing/commissioning and first-fill oils/diesel; 4 Nos 80 kVA modular online UPS (N+1, 30 min VRLA battery backup); 1 No 400 kVA 11/0.433 kV outdoor KNAN copper-wound transformer; 1 No 200 kVAR APFC panel; 2 Nos ATS-cum-UPS LT panels; 2 Nos multi-source TTA LT panels (grid + DG-1/2 + standby) with PLC auto changeover; associated cables, earthing, panels and accessories.
Part I: Construction of 2 Nos Operator cum storage room with attached toilet, complete with fittings/fixtures as drawings. Also B/R works for data centre facility, 2 cover sheds, roads/paths/hardstanding, sewage, water supply, excavation, internal electrification and finishes per drawings/particular specifications (including ATT and waterproofing deemed in Part I LS as applicable).
Entire work within 270 days from site handover per Schedule 'A' (Appendix 'A' states 300 days—conflict). Defects liability period 24 months from certified completion. Site handover about two weeks after acceptance.
Works to MES Schedule of Rates, drawings (architectural/structural/services sheets supplied), Particular Specifications, Special Conditions and IS/CPWD references cited in BoQ (e.g. CPCB IV+ for DG, CPWD specs, IS for electrical tests). GCC IAFW-2249 and DSR/SSR available for perusal at GE(I)/CE office (not enclosed).
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.
Single-stage two-cover e-tender on defproc/eprocuremes. Cover-1 (Technical/'T' bid) and Cover-2 (Financial/'Q' bid via BoQ Excel only). No physical tender bid accepted. Quote only in BoQ file; no format alteration.
Bid uploaded using DSC of authorised person. Cover-1 must include scanned POA in favour of DSC holder (or sole-proprietor affidavit / partnership/company constitutional authority docs). Fresh POA specifically covering arbitration clause required even if routine POA exists. Every page of tender to be initialled; drawings signed after acceptance.
Original DD (tender cost) and EMD instruments (as applicable) to office of Accepting Officer (Chief Engineer R&D, Opp. Jubilee Bus Station, Picket, Secunderabad-500 003) within 5 days of bid submission end date. Original Integrity Pact (each page signed) by post with DD before Cover-1 opening. Hard copies of POA/authority documents well in advance of fixed date/time.
After Cover-1 opening, deficiencies may be notified by e-mail/SMS/Speed Post; 7 days to rectify or Cover-2 not opened.
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.
No corrigendum/addendum files are present among the downloaded tender documents, and no amendment history is printed in the NIT/tender PDFs. Values in the base documents therefore apply as written (subject to internal contradictions noted separately).
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.
Appendix 'A' item 3 states period of completion 300 days, while Schedule 'A' Note 1 states entire work within 270 days from site handover. Both are in the same tender PDF without corrigendum. Bidder should seek written clarification; Schedule 'A'/contract notes are the execution clause while App 'A' is NIT summary—do not assume either silently.
Instructions para 5.5: PS Bank Guarantee validity up to and including scheduled expiry of Defects Liability Period. Special Conditions para 15.1: validity of Bond/FDR up to and including scheduled DLP expiry plus minimum 60 days.
Forwarding letter header shows Tele: 040-27890087; Appendix 'A' item 9 shows Phone No. 040 29557665. Same office/email otherwise ([email protected]).
NIT appeal clause lists NHEA fax 044-25360028 & 25360029, while Appendix 'A' Note 10 lists fax 044-29814385 for the same NHEA email [email protected].
Instructions allow EMD exemption by signing bid security declaration in Appendix 'B', but the Notice-of-Tender Appendix 'B' declaration form is not printed in the supplied pages (pages after App 'A' jump to Integrity Pact). Bidders cannot safely rely on exemption without the form/clarification.
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.
Ask Accepting Officer to confirm whether contractual completion is 270 days (Schedule 'A') or 300 days (Appendix 'A'), and whether any phase-wise intermediate milestones apply.
Clarify whether PS BG/FDR must run to DLP expiry only or DLP + 60 days, and the claim period required by Accepting Officer/PCDA.
Request the missing Appendix 'B' bid-security declaration proforma, or written confirmation that EMD ₹5,18,500 physical instrument is mandatory for non-SSD bidders with no declaration option.
Request the exact MES Manual 2020 Para 1.4/1.5 numerical criteria (similar-work values, average annual turnover, solvency, working capital) that will be applied for this Class A / b(i)&b(ii) tender, and what counts as 'similar nature' for DG/electrical data-centre works.
Seek approved makes/OEMs for 160 kVA CPCB IV+ silent DG sets, factory inspection/witness requirements, fuel for testing responsibility beyond first fill, and whether all 4 sets run in parallel/N+1 with the specified multi-source LT/PLC scheme.
Confirm CABS/DRDO site access lead times for men/materials/cranes, normal working hours, Sunday/holiday work permissions, police verification requirements for workmen, and any ban on photography/digital records constraints affecting commissioning documentation.
If not already taken from the live defproc critical-date table, confirm bid submission start, bid submission end (and whether 18:00 hrs applies), and Cover-1/Cover-2 opening dates/times in writing.
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.
270 vs 300 day conflict can shift LD/compensation-for-delay exposure. Detailed LD formula sits in IAFW-2249 (not enclosed). Conciliation expressly covers disputes on levy of compensation for delay.
Entire work in restricted area; Official Secrets Act binds contractor; fire precautions; identity of workmen; likely access delays for heavy DG/transformer installation can compress an already tight programme.
5% PS for full contract, BG validity at least through 24-month DLP (possibly +60 days), forfeitable on cancellation under Conditions 52–54. Separate ATT retention 2.5% for 10 years on ATT component.
Missing scanned/physical tender fee or EMD can kill Cover-2 or trigger 6-month ban. L1 revocation/upward revision after Cover-2 attracts EMD-equivalent penalty and retender; related firms barred from subsequent calls. IP non-upload = automatic rejection.
Cannot sublet or POA the work to another firm—critical for multi-discipline DG, HT/LT, UPS, civil package at a restricted DRDO site.
Rates inclusive of GST/cess on bid-due-date basis; only percentage-linked contract-value taxes get reimbursement/refund with strict documentary proof—mis-estimation of tax is bidder risk. Unquoted BoQ items become Nil.
Even enlisted Class A bidders have no guarantee of T-bid validation/finance-bid opening; appeal to NHEA only before finance-bid opening, no compensation for rejection.
Joint CPM required; GE reviews can revise schedule without automatic EOT; multi-shift/incentive methods to meet schedule attract no extra payment.
The inviting authority and relevant contacts: office, person, designation, address, phone and email — and which address receives physical submissions, if any.
