Objectives

The primary objective of this tender is to supply and execute urgent repairs and replacements for two faulty centrifugal water pumps at the South African Police Service (SAPS) facility in Jozini. The successful bidder will be responsible for dismantling defective units, installing new compliant pumps, and ensuring full operational testing and commissioning within a one-month period.

Scope of Work

The contractor must conduct a mandatory site inspection prior to submission. The scope includes:

• Removing existing pumps and safely isolating cabling.
• Inspecting motor windings, insulation, safety switches, low/high-level cut-outs, electrodes, and control panels.
• Replacing both water pumps with units matching specified hydraulic and motor parameters.
• Repairing or replacing electrical timers, fittings, overload switches, Grundfos chamber stack kits, O-rings, and mechanical seals.
• Inspecting and rectifying pipe fittings, flanges, brackets, couplings, strainers, non-return valves, and pressure control valves.
• Proper installation, earthing, automation, alignment checks, and setting of running amps and pressures.
• Testing and commissioning all systems to ensure optimal functionality.
• Providing a comprehensive safety plan, issuing a Certificate of Compliance, and maintaining a minimum six-month warranty or manufacturer’s guarantee on all replaced parts and workmanship.

All quantities are re-measurable, and pricing must be firm. The contract carries an urgent delivery requirement, mandating immediate commencement upon receipt of an official order.

Technical Requirements

Bidders must adhere to strict technical specifications and regulatory standards:

• Pump Specifications: Centrifugal type with a maximum flow rate of 100 litres per minute, maximum head of 30 metres, minimum head of 17 metres, suction height of 7 metres, and approximately 2.94 bar at zero flow.
• Motor Specifications: 0.75 kW rated power, 230V single-phase, 50Hz frequency, 5A current draw, and 3000 revolutions per minute.
• Installation Standards: Equipment must be installed on a level, solid surface with adequate clearance for cooling and maintenance. Piping must be leak-free, with suction lines sloping upward toward the pump.
• Compliance: All work must comply with the Occupational Health and Safety Act (Act 85 of 1993), relevant SANS standards, municipal by-laws, and manufacturer specifications. Original materials and equipment are mandatory.
• Warranty: A minimum twelve-month warranty covers all supplied components and labour.

Skills and Qualification Requirements

Suppliers must demonstrate technical competence, financial stability, and regulatory compliance:

• Professional Registration: Contractors must hold a CIDB contractor grading designation of 1ME or higher and employ qualified mechanical artisans/technicians with verifiable proof of qualifications.
• Statutory Compliance: Valid registration with the Compensation Fund (COIDA) and a current letter of good standing are mandatory. Bidders must also submit a SARS Tax Compliance Status PIN or TCS certificate.
• Financial & Administrative Documentation: Submission of a completed Central Supplier Database (CSD) number, board resolution authorising the signatory, and a fully priced Bill of Quantities with clear breakdowns for labour, materials, transport, and markup.
• Preferential Procurement: Evaluation follows an 80/20 scoring system (80% price, 20% specific goals). Points are allocated for Black Economic Empowerment (BBBEE) status, including ownership by black people, black women, persons with disabilities, or youth, alongside local municipality presence. A SANAS-accredited BBBEE certificate or sworn affidavit is required.
• Evaluation Criteria: Responsiveness checks include past project experience (5–10 years), contractual performance history, human resource capacity, and financial viability. Non-compliance with administrative or substantive criteria results in disqualification.

Terminology Notes: CIDB Grading is the Construction Industry Development Board classification system that certifies a contractor’s financial turnover and technical capacity to undertake construction works. COIDA refers to the Compensation for Occupational Injuries and Diseases Act, requiring employers to register and contribute to a statutory fund covering employee workplace injuries. Re-measurable quantities indicate that final payment will be calculated based on actual measured work completed rather than fixed initial estimates. BBBEE Preference Points are government-mandated scoring allocations designed to prioritise historically disadvantaged businesses and promote economic transformation in public procurement.
