180 days from opening of the Price Bid, using the more specific checklist wording. Part I(B) instead says 180 days from opening of bids; this conflict should be clarified and is recorded under contradictions.
Tender value or estimated cost, EMD/bid security (amount, acceptable forms, validity), tender document fees, performance security, and key payment terms.
No fixed estimated cost/tender value is stated; bidders quote Total Project Cost, DRDO share sought and DA share. Under the more specific Special Terms, projects up to INR 10 Crores are generally eligible for up to 90% DRDO funding (up to 100% case-by-case), and projects above INR 10 Crores up to INR 50 Crores for up to 70%.
The supplied tender documents state no EMD/bid-security amount, tender-document fee, or performance-security requirement. The only specified security is a 100% collateral Bank Guarantee when the DA chooses advance funding; no validity or claim period for that BG is stated.
Funding is milestone-based, with no more than five milestones. The bidder may choose advance against a 100% collateral BG or reimbursement; later instalments require a project update report, Utilization Certificate and Statement of Expenses, and a Chartered Accountant certificate. Funds are transferred pro rata into a dedicated no-lien single bank account.
The RFP says all taxes, duties, levies and charges are included in total project cost and caps contingency at 3% and overhead/miscellaneous at 10%. Unused funds must be refunded; if grant-in-aid becomes a source of profit, the refund bears 10% annual interest. The BOQ simultaneously labels DRDO funds sought as excluding GST while its terms say all costs include GST; pricing treatment needs clarification.
Every pass/fail eligibility and qualification requirement: experience and past performance, turnover/net worth, registrations and certifications, consortium/JV rules, and debarment or blacklisting conditions.
Bidder must be an Indian-registered private entity of a permitted form, or an autonomous body engaged in R&D with manufacturing infrastructure. It must be owned and controlled by resident Indian citizens; foreign investment above 49% is disqualifying. DPSUs/PSUs are ineligible.
Entities debarred, banned or blacklisted, or whose business dealings are suspended/put on hold by MoD/GoI, are ineligible; specifically covered allied/subsidiary firms are also ineligible.
Pass/fail Part IV(B) requires all three: design and development of a GaN-based SSPA above 1 kW; experience in high-power electronics/pulsed power/HPM systems above 10 kW; and successful delivery of a pulsed high-power transmitter above 4 kW at S/C/X band.
Bidder/industry partner must have, in-house or through collaboration, RF design/CAD tools, GaN amplifier and antenna development/testing facilities, and at least one person with at least two years’ experience in each specified domain: RF systems/high-power SSPAs above 1 kW and thermal-management design/simulation for electronics.
Only bidders passing Part IV(B) are scored under Part IV(C); at least 60 out of 100 marks is required for the next stage. No Startup/MSME exemptions apply.
For DAs already awarded TDF projects, performance adjusts the technical score: +5 for completion within timeline; 0 for one PDC extension; -3 for two or more PDC revisions; -1 where discontinued for excessive technical challenge; and -5 for cancellation/incomplete work due to DA inability.
Lead industry may collaborate with academia/R&D (maximum 40% contribution) and up to two other industry partners. Each industry collaborator must independently meet eligibility and submit its certificate. A collaborating industry cannot also bid individually or collaborate in another bid. Foreign technical/academic collaboration is allowed but must be disclosed in the DPR.
A firm may concurrently hold a maximum of two TDF projects at bid closing unless the competent authority approves more. No minimum turnover or net-worth threshold is stated; only last-year financial statements and a CA-certified foreign-shareholding limit are requested.
What is being procured: the work, supplies or services, deliverables and quantities, locations, phases, completion or delivery timelines, applicable standards, and notable exclusions.
Develop one modular, scalable S-band High-Power Microwave Integrated Evaluation System (SHIELD) using GaN SSPAs and an active phased-array antenna, for controlled electronic-vulnerability testing on the ground and a drone-mountable/counter-drone pathway.
Required operating frequency is 2.9–3.4 GHz; target ERP 4.4–4.6 MW; antenna gain 23–27 dB; typical beam width 8°–10°; configurable 1–200 µs pulse width; repetition rate up to 5 kHz; and peak electric field at far-field distance at least 3 kV/m. Maximum envelope is 0.9 m × 0.9 m × 0.9 m and 100 kg.
Baseline system includes one 8×8 patch-array antenna, 64 SSPA modules, one front radome, two battery units, one synthesizer, one mechanical housing and one forced-air cooling system. Any extra quantities needed for testing/evaluation are to be supplied by the industry partner.
The stated indigenous-content requirement is 60% to 70%. GaN amplifier chips may be sourced from Friendly Foreign Nationals/Indian firms, but GaN SSPA design/development, synthesizer, power supply, antenna, thermal management, ground control/health monitoring, enclosure and 30-minute airborne battery operation are mandatory indigenous technology areas.
Acceptance/qualification is against an ATP based on the stated technical parameters, finalized after DDR/CDR. The DA must complete sub-system and prototype tests, approved reports, lab/field-trial readiness and final prototype delivery; the RFP does not identify a fixed delivery/trial site, only a location later specified by DRDO.
Tentative duration is 30 months from T0: PDR by month 5; DDR and design package by month 12; functional prototype/testing and ATP by month 22; acceptance testing and one prototype by month 26; and complete documentation/project closure by month 30. Milestone timing and completion percentages may be finalized during CNC with PMMG.
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.
Submit electronically on https://defproc.gov.in in two separate covers: techno-commercial bid and price bid. The price bid must be the supplied BOQ only; no physical or emailed bid documents are accepted.
Register one valid Class III DSC with signing-key usage, issued by a CCA India-recognized authority; digitally sign and upload each required document. Attachments should be PDF. Fill the BOQ without changing filename, structure or other cells.
Forms requiring firm letterhead must be duly typed, signed and stamped/sealed by the authorized signatory. Do not disclose any project cost in the technical bid; doing so causes rejection.
To attend pre-bid, email the eligibility certificate, authorized representative’s details and identity proof/PAN/Aadhaar to [email protected] in advance; the printed certificate says at least 24 hours before the meeting. This is separate from the online bid and is the only stated email submission.
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.
The AI found nothing to report for this question.
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.
The BOQ total column says DRDO funds sought are excluding GST, but the BOQ terms and RFP say all project costs include GST/taxes. No corrigendum resolves this. Obtain written clarification before pricing; the RFP’s explicit total-project-cost inclusion language is broader, but the locked BOQ field cannot be altered.
Part I(B) starts 180 days at opening of bids, while the mandatory checklist starts it at opening of the Price Bid. The checklist is the specific bidder declaration and should be used unless DRDO clarifies otherwise.
Standard Terms say up to INR 10 Crore receives maximum 90% and above INR 10 Crore receives 70%, without an upper project limit or 100% exception. Special Terms add possible 100% funding case-by-case and limit the >10 Crore band to projects up to INR 50 Crores. The later, more specific Special Terms should govern.
The NIT identifies Director, Management & Security as procuring authority, while the RFP/BOQ identify Director DTDF. The RFP page header gives fax 91-11-23014762, but its contact block gives 91-11-23013462. For tender queries, the detailed RFP directs bidders to Director DTDF/Sh. Vivek Kumar and email [email protected]; verify any fax use first.
The BOQ extraction contains unrelated civil-work descriptions (‘Construction of chamber...’ and ‘Supplying, Conveying and fixing...’) alongside the SHIELD project. These appear to be residual template cells and conflict with the project item. Do not alter the locked BOQ; ask the portal authority to confirm that bidders should fill only the SHIELD/Total Project Cost fields.
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.
Should DRDO Share sought be entered exclusive of GST as the BOQ column says, or inclusive of GST as the BOQ terms and RFP require? Specify where GST is to be entered and whether L1 comparison is GST-inclusive.
The BOQ contains unrelated civil-work residual text. Confirm the exact cells bidders must fill for Total Project Cost, DRDO share and DA share, and issue a corrected locked file if those residual cells affect validation/evaluation.
Does the project require a minimum of 60%, 70%, or a negotiated value within 60%–70%; how will the percentage be computed and evidenced, and does FFN sourcing of the GaN chip count as indigenous content/background IP?
Confirm whether the one prototype must be flight-qualified and physically integrated on a drone, whether a drone/airframe is buyer-furnished, the acceptance and field-trial sites/ranges, target far-field distance, target set, permits/safety support, and which party bears logistics and trial consumables.
Define T0, approval durations, milestone acceptance authority, reimbursement turnaround, advance-BG validity/claim period/reduction/release, and whether the tentative 5/12/22/26/30-month schedule and 10/15/25/30/20 payment shares may materially change at CNC.
Confirm that no EMD, tender fee or separate performance security applies, and state whether the 180-day validity runs from initial bid opening or Price Bid opening.
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.
Advance funding requires a BG equal to 100% of advance; otherwise the DA must finance work until reimbursement. DRDO may withhold payments for missing bonds, guarantees, documents or milestone deliverables, while milestone dates and shares remain subject to CNC finalization.
Unused funds must be refunded. If audited accounts show the grant became a source of profit, refund is due with 10% annual interest. Revenue-generation activities and numerous cost categories are unallowable, including loan principal/interest, land, legal expenses/penalties, business development, losses and reorganization costs.
All foreground IP is DRDO property, with joint ownership only as DRDO policy may allow. A project-asset agreement controls tangible/intangible outcomes; the DA cannot transfer project equipment, technology, drawings, information or IPR without written consent. Project accounts are open to sanctioning-authority, CAG and Defence Accounts audit.
DRDO may vary or foreclose the project without financial commitment and disqualify a firm at any stage on national-security grounds. DRDO disclaims compensation to the DA for any reason, while the DA indemnifies labour-law and third-party IP claims.
The 30-month deep-tech schedule requires a 4.4–4.6 MW ERP, at least 3 kV/m far-field output, a ≤100 kg modular/drone-mountable package, indigenous-content obligations, and one accepted prototype. ATP is finalized only after DDR/CDR and trial location is later specified, leaving acceptance setup and logistics uncertain at bid stage.
No conventional delay-LD rate is stated. However, undue influence can trigger termination, penal damages, BG forfeiture, repayment and recovery of loss. Failure to answer evaluation queries can make the bidder a default bidder; three defaults cause one-year ineligibility for DRDO RFPs.
The locked BOQ has contradictory GST wording and unrelated civil-work residual text. Because modifying it causes rejection, an unclarified template creates both commercial and responsiveness risk.
