Tender Summary

Objectives

The primary objective is to restore and maintain reliable hot water supply systems at Niemeyer Memorial Hospital through targeted after-service repairs of malfunctioning heat pumps and calorifiers. The project aims to ensure uninterrupted, safe, and energy-efficient operation of critical clinical and kitchen utility infrastructure.

Scope

This is a one-off service contract requiring on-site diagnostic assessment and remedial repairs across two designated hospital zones: the workshop and the kitchen. The contractor will execute specific maintenance interventions on existing equipment, including sensor replacement, electrical rewiring, gas leak rectification, refrigerant recharging, pump and thermostat replacements, and circuit breaker upgrades. All deliverables must be completed directly at the hospital premises.

Technical Requirements

• Workshop Heat Pump: Replace discharge and water return sensors; rectify incorrect electrical terminations through proper rewiring.
• Kitchen Heat Pump: Identify and repair gas leak, recharge refrigerant system, replace thermostat, and install a new 0.75kW circulation pump.
• Kitchen Calorifier: Replace a 35A three-pole circuit breaker (specification: C3 QA3-G3-M 415V 3kA).
• All supplied components must be new, unused, and compliant with applicable South African standards. Second-hand, refurbished, or expired products are strictly prohibited.
• Quoted prices must be all-inclusive, covering labor, materials, transport, and VAT (where applicable). Prices must remain firm throughout the contract period.
• Standard warranty provisions apply, guaranteeing freedom from design, material, and workmanship defects under normal operating conditions.

Skills Requirements

Although not explicitly itemized, the technical scope necessitates certified competencies in HVAC systems, refrigeration engineering, and electrical maintenance. Bidders must demonstrate proven experience in:

• Refrigeration cycle diagnostics and safe gas leak detection/repair.
• Low and high-voltage electrical rewiring, sensor calibration, and control board troubleshooting.
• Thermal system maintenance, pump integration, and circuit protection upgrades.
• Adherence to occupational health and safety regulations, particularly in healthcare environments.

Notable Terms & Conditions

• After-Service Repair: Refers to post-installation maintenance focused on restoring original equipment functionality rather than supplying new units. This requires specialized diagnostic capabilities and OEM-compatible replacement parts.
• 80/20 Preference Point System: A South African public procurement framework allocating 80 evaluation points for competitive pricing and 20 points for socio-economic transformation. Full points are awarded to companies that are 100% owned by Black Africans.
• GCC/SCC Framework: Standard government contract conditions governing performance security, delay penalties, termination rights, tax compliance verification, and dispute resolution. Failure to meet these conditions results in automatic disqualification.
• SBD Documentation: Mandatory submission of standardized bidding forms for conflict-of-interest disclosure, preference point claims, and Central Supplier Database registration validation.
