Cleaning service for the sludge blanket clarifiers at Duvha Power Station's water treatment plant, delivered in two parts.

• Online cleaning keeps the top of the clarifier clear of scale and algae without draining it, so debris does not carry over into production systems.
• Offline cleaning strips all water-contact surfaces so that corrosion and structural damage can be identified during inspection.

Completion sign-off

• After cleaning, Eskom personnel and the contractor carry out a joint quality inspection of the clarifier.
• Eskom signs off the task as complete only after that inspection.

Method statement

• The contractor submits a cleaning method statement to the project manager for acceptance.
• A revised method statement must be accepted before any deviation from the original submission is implemented.
• The cleaning method for offline work is chosen by the contractor but requires Eskom approval.

Scope

• Cleaning of the sludge blanket clarifiers at Duvha Power Station water treatment plant, split into online cleaning and offline cleaning.
• Online cleaning covers the top of the clarifier: peripheral and radial launders, the outer launder to the recarbonising area, and the clarifier 157 channel to the demineralised/potable sump.
• Offline cleaning covers all water-contact surfaces so that corrosion and structural damage can be inspected.

Online cleaning

• Applies to the six big clarifiers only, and only while they are in service.
• Frequency: once every two months for the contract period.
• The clarifier is not drained; the supply inlet valve is closed and the sluice gate to the cooling towers opened.
• Potable and demineralised water clarifiers: cleaning limited to 4 hours per day because of production demand, with all radial and peripheral launders finished within 8 hours in total over two consecutive days.
• Method: high-pressure water with algae and deposit removal equipment that does not damage the launders.
• The moving bridge is used as the working platform; safety harnesses are hooked onto the bridge and PPE per the task risk assessment is worn.

Offline cleaning

• Applies to both big and small clarifiers.
• Surfaces cleaned: peripheral and radial launders; mixing zone above and beneath the centre cone plus impellers; inlet pipe; concrete walls; pockets and associated pipelines; outlet launder to the recarbonising area; recarbonising area.
• Duration: 14 days for a big clarifier, 8 days for a small clarifier.
• After the permit to work is issued, the contractor drains the clarifier through the blow-down drain valve and pumps out remaining water once the settled sludge becomes visible.
• Access to the clarifier floor uses a secure stepping arrangement approved by Eskom.
• Equipment must not damage the clarifier's construction materials.

Evaluation sequence

1. Basic compliance check — a bid failing these requirements is non-responsive.
2. Mandatory returnables — a bid missing any stipulated mandatory document or information is disqualified.
3. Pre-qualification criteria, where stipulated; no criterion is measured twice across phases.
4. Functionality, where applied — bidders must meet the minimum threshold stated in the Tender Data to progress.
5. Financial analysis — Eskom assesses the financial risk of contracting with the bidder; where risk is too high, or mitigating factors are absent, insufficient or rejected by the bidder, the bid is not considered for award.
6. Price evaluation, taking into account factors such as CPA, FOREX, commodity exposure, unconditional discounts, technical adjustment, PV and forecast invoicing rates.
7. B-BBEE scoring against the CSD report, certificate or affidavit.
8. Specific Goals scoring against submitted supporting documentation.

Preference points

• Price and Specific Goals scores are added and bidders ranked highest to lowest under the 80/20 or 90/10 system.
• A bidder that does not meet Specific Goals, or does not submit the proof by the closing time, is not disqualified but scores zero for Specific Goals.
• A bidder without a B-BBEE certificate or affidavit at closing, or whose certificate is fraudulent or expired, scores zero for B-BBEE preference points (unless B-BBEE is a pre-qualification criterion, in which case the bid is disqualified).

Other evaluation rules

• Reverse e-auction may be used; where it applies, bidders submit a complete tender without prices and any prices included are disregarded.
• Award may depart from the highest points only on Objective Criteria stated in the Invitation to Tender; functionality and B-BBEE scorecard elements may not serve as Objective Criteria.
• Arithmetical errors: amounts in words prevail over figures. Bidders are notified and may confirm or accept correction; refusing correction results in rejection. Where the bidder confirms its prices, the line-item total prevails over a misapplied unit rate, and the total of the prices prevails over addition errors.

Pricing the tender

• All duties, taxes (including VAT) and levies applicable 14 days before the closing date and time must be built into the rates, prices and tendered total.
• Rates and prices are fixed for the contract duration and not subject to adjustment except as allowed in the Invitation to Tender.
• Prices are stated in South African Rand unless the Invitation to Tender directs otherwise; where part payment in another currency is provided for, the exchange rate and base date in the Invitation to Tender apply.
• Where cataloguing is required, a separate line item must be priced; Eskom pays for cataloguing.

Pricing schedule and bill of quantities

• Every line must be completed; omissions in the pricing schedule or bill of quantities are treated as errors or omissions.
• Arithmetical checks cover misplaced decimal points, incorrect multiplication of unit rate by quantity, incorrect addition, and use of fewer than four decimal places or an incorrect exchange rate.
• Amounts in words prevail over figures.
• Bidders are asked to confirm their prices or accept corrections; if they confirm, the line-item total prevails over a faulty unit rate and the total of the prices prevails over addition errors, with selected item prices revised to match the tendered total.
• A bidder that does not correct or accept correction of errors has its tender rejected.
• Mandatory returnables may not be submitted or supplemented after the closing date and time; price breakdowns requested during evaluation may not change prices or the substance of the bid, except to correct arithmetical errors.

Pricing

• Prices must be stated in South African Rand unless the Invitation to Tender directs otherwise.
• Rates and prices must include all duties, taxes (including VAT) and levies applicable 14 days before the closing date and time.
• Rates and prices are fixed for the contract duration, with no price adjustment except as provided in the Invitation to Tender.
• Where a bill of quantities or pricing schedule applies, every line must be priced; omissions are treated as arithmetical errors or omissions.
• Where cataloguing is required, the pricing schedule must carry a line item for it; Eskom pays for cataloguing.

Security and insurance

• Where performance security is required, the bidder must name at least two financial institutions it may approach; Eskom may reject an unsuitable institution.
• Insurance provided by Eskom may not cover the full extent required under the conditions of contract; bidders should obtain their own advice.

Cost of bidding

• Eskom does not reimburse any cost of preparing or submitting a tender, including testing costs or negotiation costs.

Eligibility

• The bidder must meet the eligibility criteria in the Tender Data and must not be restricted from doing business with Eskom or any State-Owned Company.
• Sub-contracting 100% of the scope renders the bid ineligible and it will be disqualified.

Statutory and registrations

• CSD registration and a B-BBEE certificate, CSD report or sworn affidavit; where B-BBEE level is a pre-qualification criterion, proof is due at the closing time or the bid is disqualified.
• Where sub-contracting to designated groups is a pre-qualification criterion, the sub-contractor's B-BBEE status and CSD number or certificate/affidavit are required at closing.
• CIDB registration where a grading is stipulated: proof of registration is mandatory at closing; proof of application is accepted at closing only if the actual CIDB printout follows by contract award.
• Compliance with National Treasury instruction notes, PPPFA regulations, the amended B-BBEE Codes, COIDA, the OHS Act, dtic local content designations and CIDB regulations for construction work.
• SHEQ: proof that safety, health, environment and quality systems, policies and capability are in place at closing and/or contract award; all SHEQ costs and personnel must be priced into the tender.

Contract-stage obligations

• Contract Skills Development Goals apply to contracts of 12 months or more and either R5 million or more (services or professional services) or CIDB grade 7 and above (engineering and construction).
• Contract Participation Goals apply to GB and CE construction contracts of at least 6 months where at least 25% of the main contract can reasonably be subcontracted in the CE, EB, GB or ME classes.

Integrity

• Misrepresentation or falsification of any information, certificate, affidavit or document leads to disqualification; B-BBEE fraud or fronting is reported to the B-BBEE Commission, with suspension from State-Owned Company business of up to 10 years and possible imprisonment.
• Proof that a bidder influenced the evaluation or award, colluded, rigged bids or engaged in fraudulent or illegal activity is grounds for rejection.

Contract-stage

• The successful bidder may be required to supply cataloguing information and label materials to Eskom's labelling specification.
• Contract documents are revised to reflect addenda, returnables, negotiated changes and other agreed revisions.

Evaluation stages

• Basic compliance is determined before detailed evaluation; failure renders the bid non-responsive.
• Mandatory returnables missing at the closing time disqualify the bid.
• Pre-qualification criteria apply where stipulated, with no criterion measured twice across phases.
• Functionality, where applied, carries a minimum threshold stated in the Tender Data that must be met to proceed.
• Financial analysis assesses the risk of contracting with the bidder; unresolved or unmitigated high risk removes the bid from consideration.
• Price is evaluated on the criteria in the Tender Data, factoring in CPA, FOREX, commodity exposure, unconditional discounts, technical adjustment, PV and forecast invoicing rates.
• B-BBEE is scored from the CSD report, certificate or affidavit; where it is a pre-qualification criterion, missing, fraudulent or expired proof disqualifies the bid.
• Specific Goals are scored from supporting documentation; failure to meet them or to submit proof scores zero for that component without disqualification.

Ranking and award

• Price and Specific Goals scores are combined and bidders ranked highest to lowest under the 80/20 or 90/10 system.
• Award to a bidder other than the highest scorer is possible only on Objective Criteria stated in the Invitation to Tender; functionality and B-BBEE scorecard elements cannot be used for this purpose.
• Reverse e-auction may be used; bidders then submit a complete tender without prices, and any prices included are disregarded.

Returnable document
