• Cover-I is opened only for bidders whose tender cost, processing fee and EMD payments are found in order.

Price bid opening

Online opening of the price schedule/BOQ will be intimated later only to techno-commercially qualified bidders.

Bid validity

Bid validity is 180 days from Techno-Commercial (Cover-I) bid opening, extendable with bidder consent.

• Tenders stating a shorter validity are likely to be ignored; if validity is not stated, 180 days is presumed.
• During validity the tenderer shall not withdraw or impair the offer; acceptance within validity binds the bidder until formal contract execution.

Pre-bid / clarification deadline

No pre-bid meeting date or formal clarification-submission deadline is prescribed in the tender documents.

• Bidders are only generally told to seek necessary clarification before submitting the offer if any doubt exists on conditions or site.

Contract period and unit completion time

Contract period is one year from commencement, extendable by three months; each unit's condenser cleaning must finish within 12 days from condenser isolation.

• One-year contract may be extended three months on same rates/terms, but if lower rates are received in a new contract those lower rates apply to the extension.
• Failure to complete a unit within 12 days attracts 1% per day of contract value, capped at 5%.

Estimated cost / tender value

Estimated cost is Rs. 47,32,208.00, matching G-Schedule and BOQ totals.

• G-Schedule: hydro-jetting 4 Nos @ Rs. 11,63,052 = Rs. 46,52,208.00; tube re-expansion/flaring 2000 Nos @ Rs. 40 = Rs. 80,000.00; total Rs. 47,32,208.00.
• BOQ is a percentage BoQ on estimated rate Rs. 47,32,208 for the whole work.

EMD / bid security

EMD is Rs. 94,650/- payable only by digital RTGS/NEFT in a single transaction with tender cost and processing fee; no interest; successful bidder's EMD converts to security deposit.

• Payee account: Assistant Accounts Officer, CTPP, RVUNL / Assistant Accounts Officer (CTPP), RVUN, Chowki Motipura; SBI A/c 61005208761 (also written 00000061005208761); IFSC SBIN0031988; MICR 325002019; branch Motipura Chowki, Chhabra, Baran.
• Unsuccessful bidders get refund on application with original receipt; adjustment of other EMDs already with Nigam is not allowed.
• Bidder not depositing EMD shall be rejected; Nigam may forfeit EMD if contractor is not interested in executing the order or breaks conditions.
• NEFT/RTGS confirmation may take 4–24 hours, so pay well before deadline.

Tender document fee and processing fee

Tender document cost is Rs. 590/- (Rs.500 + GST@18%) and e-procurement tender processing fee is Rs. 500/-; both via the same single digital transaction as EMD.

• Scanned payment confirmation advices for all three amounts must be uploaded in Cover-I.

Security deposit and unbalanced-bid additional performance security

Security Deposit @ 10% is deducted from running bills (EMD adjusted into SD); unbalanced L-1 bids more than 15% below estimate must deposit additional performance security equal to 50% of the unbalanced amount.

• SD refundable on request after three months of satisfactory completion of entire contract period, subject to PF statement (cl.15.00) and ESI (cl.43) compliance; no interest; forfeitable for failure/neglect of obligations.
• Unbalanced bid amount = positive difference of 85% of estimated bid value minus quoted bid amount; additional PS refunded only after satisfactory completion and forfeited if work not completed within stipulated period.

Pricing, taxes and payment terms

Quoted prices are FIRM and inclusive of all taxes/duties except GST (extra at actual); 100% payment after SD/tax deductions on work done, with bill-support documents; quantities are indicative and paid on actuals.

• GCC 11.01: monthly payment basis by AO/AAO, CTPP after satisfactory performance.
• Section-C clause 9: running bill released on completion of one work i.e. one unit (conflicts with monthly wording; Section-C prevails over Section-B for this contract).
• Monthly bill in triplicate must attach PF/ESI challans, attendance, PF schedule/undertaking, previous month payment sheet, labour licence if applicable, insurance cover note, and GST deposit undertaking.
• Contractor must register with Central Excise/GST before first bill; give GST deposit undertaking with each bill; submit quarterly GST deposit proof.
• Nigam does not guarantee payment of entire contract value; work may increase/decrease as per actual requirement.
• Statutory TDS as applicable from running bills.
• Wages escalation note: if quoted rates exceed notified government wages, subsequent minimum-wage variation is not payable by RRVUNL; wage escalation not applicable on AMC/repair outside CTPP premises.

Similar work experience (last 7 years)

Bidder must have completed/under-execution remote-controlled mechanized HP hydro-jetting of condenser tubes at 1000 bar in thermal units ≥210 MW or similar process-industry condensers during last 7 years ending last day of month previous to NIT, meeting 80%/50%/40% value thresholds.

• One annual contract ≥80% of estimated cost excluding taxes = Rs. 37,85,766.40; OR two ≥50% each = Rs. 23,00,104.00; OR three ≥40% each = Rs. 18,92,883.20.
• Work orders must be directly placed on the bidder; sub-let experience not considered.
• For completed work, work-order value is considered; for under-execution work, progressive value achieved must meet QR thresholds with documentary evidence.
• A biennial contract is treated as two annual contracts of 50% contract value each.
• Performance/completion certificates must be signed by order-placing authority; for RVUN works, by Chief Engineer/In-charge of Power Station/Project.

Machine ownership / availability

Bidder must have at least 6 machines (including 2 standby) of min. 150/200 HP, 1000 Bar+, 70 LPM discharge.

• Evidence: any documentary evidence or self-attested declaration with machine details.

Average annual financial turnover for FY 2023-24, 2024-25 and 2025-26 must be at least 30% of estimated cost (Rs. 14.20 lakhs); other income excluded.

• Submit CA-attested audited balance sheets with UDIN, or ITRs for those years; RRVUN may still demand audited trading/P&L/balance sheet.

Registrations and statutory credentials

Mandatory active PF, ESI, GST and PAN; Baran district labour licence with bid if required, else notarised Rs.100 NJSP undertaking to obtain within one month of LOI or work start, whichever earlier.

• GST proof: GSTIN registration plus latest GSTR with GSTIN status active.
• PF: code allotted by RPFC; ESI: ESI code registration.

Debarment / blacklisting and CTPP running-contract performance

Self-attested declaration that the firm is not debarred/blacklisted by any organization is mandatory; bidders with a similar running CTPP contract must also submit satisfactory performance up to the month previous to NIT publication.

• Annexure-A further requires declarations on competence, tax payment, insolvency/bankruptcy status, criminal offences/debarment in last three years, and absence of conflict of interest under RTPP Act Section-7.

Single-bid / conflict and capability rules

Only one tender per bidder/firm; more than one bid causes disqualification of all involved bids; bidder must be itself capable with manpower and T&P; subletting only with RVUN written consent.

• Wrong information may cause rejection at any stage.
• Conditional tenders / deviations are generally not acceptable and may be rejected.
• No consortium/JV eligibility framework is provided in the documents.

Work description and location

Remote-controlled mechanized high-pressure hydro-jetting cleaning of condenser tubes at 1000 bar for 250 MW Units 1–4 at CTPP, Chhabra, plus re-expansion/flaring of condenser tubes.

• Each 250 MW unit condenser has 15,664 SS tubes, each 11.0 m long, OD 28.575 mm.
• Work is executed during annual/capital shutdown of the unit; timely completion is essence of contract.

Quantities and BOQ items

G-Schedule covers hydro-jetting for 4 units and re-expansion/flaring of 2000 tubes (both ends); total estimated Rs. 47,32,208.00.

• Item 1: Remote controlled Mechanized High Pressure Hydro Jetting ... unit#1,2,3&4 — Qty 4 Nos @ Rs. 11,63,052 = Rs. 46,52,208.00.
• Item 2: Re-expansion / flaring of condenser Tubes (Both ends) — Qty 2000 @ Rs. 40/tube = Rs. 80,000.00.
• Quantities are indicative; payment on actual satisfactory work done.

Equipment, manpower and contractor-supplied items

Per unit under shutdown: mobilize four jet pumps and two tube-flaring machines (electrical and air-operated) with accessories, spares and skilled manpower for continuous round-the-clock cleaning.

• Operating jet pump specs: Pressure 1000 Bar and above; Discharge 70 LPM; Power input 150/200 HP.
• Flexible lances, nozzles, connectors, splitters, scaffolding (if required), T&P for pump maintenance, and consumables (24 V transformer/bulbs/holders/wire, cotton waste, etc.) are contractor scope.
• Electricity and water free at one point by CTPP; accommodation for supervision personnel chargeable subject to availability.
• Agency must provide test certificate for high-pressure lances and fittings.
• Improper cleaning must be repeated free as directed by Engineer-In-Charge.
• Sludge/scales disposed at location indicated by Engineer-In-Charge.

Completion timeline

Each unit's entire cleaning work must be completed within 12 days from condenser isolation; overall contract duration is one year from commencement (extendable 3 months).

• Delay beyond 12 days: penalty 1% per day of contract value, maximum 5% of contract value, deducted from running bills.

Governing hierarchy of scope vs GCC

Section-C scope is to be read with Section-B GCC; if conflict/inconsistency, Section-C prevails for this contract.

Submission mode and portal

Two-part open competitive e-bid only on http://eproc.rajasthan.gov.in; offers without digital signature are not accepted.

• Bidders must register on eproc; those registered before 30.09.11 need to re-register.
• DSC Type-II or Type-III under IT Act 2000 required; helpdesk 0141-4022688, [email protected].
• Cover-I techno-commercial (all docs except price BOQ); Cover-II price schedule/BOQ only.
• Evaluation on total quoted value; L-1 on totality. For pure manpower services tie-break by highest average turnover of preceding 3 FYs (clause present in GCC though this is works).

Signing, stamping and physical originals

Every page of tender documents must be digitally signed and sealed for Cover-I; Power of Attorney/authorization needed for the DSC holder; only Tender Application Form + UTR/payment advice is required physically/by email/post before fee deadline—not the full bid hard copy.

• Self-attested/digitally signed copies of work orders, performance certificates, solvency certificate, PF and GST registrations as applicable.
• Additions/alterations/overwriting must be initialled by the signatory.
• Physical/email submission address for fee form: Superintending Engineer (TM), Room No. 307, Service Building, CTPP, Chhabra; emails [email protected] and [email protected].

Payment frequency: monthly vs per-unit running bill

Section-B says 100% payment on monthly basis, while Section-C says running bill is released on completion of one unit; for this contract Section-C prevails over Section-B.

• Section-B cl.11.01: payment against satisfactory work done on monthly basis.
• Section-C cl.9: Running bill shall be released on completion of one work i.e. one unit.
• Section-C cl.14: if conflict/inconsistency between Section-C and Section-B, Section-C prevails.

Delay penalty regimes differ between Section-C and GCC

Section-C imposes 1%/day of contract value (max 5%) for missing the 12-day unit completion; GCC cl.24 has separate daily/hourly recoveries for T&P, supervisor, breakdown response and incomplete daily work.

• Both sets of recoveries are written as applicable; bidder should assume cumulative exposure unless clarified.
• Section-C is specific to this hydro-jetting shutdown work and prevails on conflict with Section-B, but GCC cl.24 items are not identical to the 12-day rule.

Machine count: QR fleet vs per-unit mobilization

QR requires ownership/availability of at least 6 machines, while Section-C requires mobilizing four jet pumps per unit under shutdown (plus flaring machines).

• Not necessarily irreconcilable if only one unit is shut down at a time, but simultaneous multi-unit outages would exceed a 6-machine fleet if 4 pumps are needed per unit.
• Bidder should clarify planned outage concurrency and whether flaring machines count toward the 6.

Solvency certificate required without stated amount

ITB and Schedule-A require a solvency/banker's credit certificate of 'required value', but QR and other clauses never quantify that value.

• Creates a pass/fail ambiguity for Cover-I completeness.

BOQ structure vs G-Schedule itemization

G-Schedule splits work into unit hydro-jetting and tube flaring line items, while the e-procurement BOQ is a single percentage-rate item on total estimated Rs. 47,32,208.

• Bidders price only excess/less on the lumped BOQ total; actual payment still references G-Schedule quantities/actuals.

Confirm controlling payment trigger

Please confirm whether running bills are paid only after each unit is completed (Section-C cl.9) or monthly (Section-B cl.11.01), and the documents required for multi-unit months.

• Material to cash-flow and working-capital for a one-year multi-outage contract.

Shutdown concurrency and 6-machine fleet adequacy

Will more than one 250 MW unit be under shutdown at the same time? If yes, how is the QR minimum of 6 machines reconciled with 4 jet pumps required per unit?

• Also clarify whether tube-flaring machines are counted in the 6-machine QR requirement and what ownership proof is acceptable beyond self-declaration.

12-day clock start/stop and penalty base

What exact event starts the 12-day completion clock ('date of isolation of condenser'), what constitutes completion acceptance, and is 'contract value' for 1%/day the full agreement value or the affected unit's G-Schedule value?

• Also whether GCC cl.24 recoveries apply in addition to the Section-C 5% cap during shutdown jetting.

Solvency certificate quantum

What is the exact amount/form of the 'solvency certificate of required value' demanded in ITB cl.5.01 / Schedule-A, since QR is silent?

• Without a figure, Cover-I may be treated non-responsive for an undefined document.

Flaring quantity risk and percentage BOQ vs item rates

Is the 2000-tube flaring quantity a firm minimum/maximum, and how are item-wise actuals paid when the e-BOQ is only a single percentage on the lumped estimate?

• Affects pricing if flaring overruns or if one unit needs disproportionate flaring.

Under-execution experience progressive-value proof

For 'under execution' annual contracts used to meet QR, what exact certificate format/authority and cut-off date are accepted for progressive value?

• Direct-order-only rule already excludes sub-let experience; progressive-value evidence standard is still vague.

Tight 12-day unit completion with steep delay penalty

Each unit must be finished within 12 days of condenser isolation; delay penalty is 1% of contract value per day up to 5%, and timely completion is essence of contract.

• Work is shutdown-driven and round-the-clock; outage slip not caused solely by contractor may still create commercial dispute unless recorded.

Multiple parallel delay/default recoveries and risk-and-cost

GCC allows daily deductions for missing T&P (Rs.1000/day), supervisor (Rs.500/day), breakdown response (0.5%/hour after 25% of stipulated time, max 10% of particular work), 100% recovery for incomplete daily maintenance items, manpower shortfall double-hit, plus risk-and-cost execution and 7-day termination.

• Order placing authority may terminate for repeated lapses and recover losses from running bills/SD.
• Force majeure still leaves RVUN discretion to get work done at contractor risk & cost.

High security hold and unbalanced-bid extra security

10% SD deducted from RA bills (EMD converted), held till 3 months after contract completion with PF/ESI clearance; bids >15% below estimate need additional PS of 50% of unbalanced amount, forfeitable for delay.

• No interest on EMD or SD.
• Cash lock-up is large relative to ~Rs.47.3 lakh estimate.

One-sided termination, quantity and price-fall exposure

CTPP may cancel the contract at any moment without assigning reason; quantities are tentative with no guarantee of full contract value; price-fall/short-closure under RTPP Rules 29(2)(h) applies; extension may force lower new-contract rates.

• Acceptance of order presumed if not conveyed within 7 days of receipt.
• Work order terms prevail over Section-B if they differ.

Statutory labour, PF/ESI and theft blacklisting risks

Contractor bears full labour-law, insurance, PMSBY, safety-PPE and wage compliance; PF default allows 16% bill deduction; >3 theft incidents can blacklist for 3 years and cancel existing contracts.

• Police verification of workers within one month if required by security.
• Bills unpaid/unverified if site not cleaned of waste/debris.
• Dispute decision of CE, CTPP final; court jurisdiction Baran only.

Rework, free utilities limits and contractor-borne consumables

Unsatisfactory cleaning must be repeated; all lances/nozzles/scaffolding/consumables/T&P are contractor's cost; free power/water only at one available point; damage to Nigam T&P recoverable.

• High-pressure lance/fitting test certificates required—failure can stop work.
