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.
Special drought conditions measure 60 days from Work Order with start in 48 hours, while Program Schedule/GCC reckon project start as the 28th day from Work Order.
Drought special conditions bar Part/RA bills, but Clause 43 still contains standard language about deductions from each bill, pre-final bill and paid maintenance.
Clause 16 requires ONLINE or eBG only, but bid-opening Clause 24.2 still rejects bids if original EMD/EMD exemption is not received.
Eligibility item 5.a prints both '1 No' and 'should have completed – 3 Nos' for borewell/infiltration/open well experience.
Same eligibility row states both 5.72 kW or higher and 5.08 kW or higher for the single higher-capacity pump criterion.
VII(a) drought special conditions are printed as operative payment/time rules, but section VIII 'SPECIAL CONDITIONS OF CONTRACT' later says 'Not Applicable'.
Unamended IFB table still prints Period of Completion – 3 Months for IFB No.04, while Amendment Slip-1 and the rest of the bid document use 2 Months.
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 which commencement basis prevails for LD and programme: Special Conditions (from WO / 48-hour start) or Clause 37.1/GCC (start on 28th day from WO).
Seek confirmation that no RA/part bill will be paid at all, and whether any secured advance/material advance exception exists despite mobilisation advance being 'Not applicable'.
Ask whether borewell/well experience required is 1 completed unit or 3, and whether higher-capacity pump experience is 5.72 kW or 5.08 kW.
Seek written confirmation that successful ONLINE/eBG payment on the portal fully satisfies EMD, despite Clause 24.2 language on original EMD/EMD exemption documents.
Ask whether '1 no. turnkey work of Transformer Sub Station' remains mandatory given the package supplies automatic servo-controlled voltage stabilizers rather than a full substation.
Ask whether activity penalties under Special Conditions are in addition to Clause 40 LD (0.05%/week, capped at 10%), and whether automatic system notices alone create a chargeable event.
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.
Final-bill-only payment with no RA bills and no mobilisation advance forces the contractor to fully fund procurement and execution before any recovery.
2-month/60-day completion, 48-hour mobilisation, component-wise maximum days, plus LD 0.05%/week (cap 10%) and possible Rs.10,000 per activity per day.
Performance security (2–5% by bid discount), plus 5% BG for 2-year DLP and potential further 5% BG for 3 years on water-retaining structures, creates prolonged capital lock-in.
Employer may foreclose whole/part works without contractor claim to lost profit; defective construction can attract up to 10% penalty of defective work value plus rectification at contractor cost.
Existing CWSS drought-mitigation works require minimised drinking-water interruption; shutdowns need prior Engineer approval; site levels/soil data are not warranted.
False or unverifiable UDIN on CA turnover certificates is expressly treated as fraudulent practice with rejection, termination, forfeiture and blacklisting exposure.
The inviting authority and relevant contacts: office, person, designation, address, phone and email — and which address receives physical submissions, if any.
