Tender Summary: Service of Emergency Generators

Objectives

The primary objective is to guarantee uninterrupted healthcare delivery by maintaining fully operational emergency power backup systems across six provincial clinics. The tender seeks to procure a qualified service provider capable of executing comprehensive preventive maintenance on designated diesel generators, thereby minimizing unplanned downtime, protecting critical medical infrastructure, and ensuring patient safety during grid power failures.

Scope

The contract covers a one-off major service for six emergency generators located at Maphumulo, Mthandeni, Oqaqeni, Isithundu, Otimati, and Maquumbi Clinics under Umphumulo Hospital. Each service package encompasses labor, travel, and all specified consumables and spare parts. The work follows standardized preventive maintenance procedures calibrated to each generator’s capacity and engine configuration. Bidders must submit mandatory procurement documentation, including Standard Bid Document (SBD) forms, Central Supplier Database (CSD) registration, tax clearance verification, and at least two verifiable trade references demonstrating successful prior execution of similar maintenance contracts.

Technical Requirements

• Generator Specifications: Services apply to Deutz-engine units ranging from 20 kVA to 100 kVA, with model-specific maintenance protocols.
• Maintenance Procedures: Mandatory tasks include draining and refilling 15W-40 engine oil, replacing air, oil, and fuel filters, flushing the engine block and radiator, adding 90–99% coolant, and inspecting the crankcase heater, drive belts, diesel pump, injectors, and coolant sight glass.
• Electrical & Control Systems: Verification of electrical control panels, changeover switches, automatic voltage regulators, alternators, and automation controllers.
• Quality Standards: All parts, fluids, and workmanship must comply with SABS, SANS, SANAS, or SAQCC certification requirements.
• Evaluation Framework: Offers are scored using an 80/20 preference point system, where 80 points are allocated for competitive pricing and 20 points for socio-economic transformation, specifically granting full points to enterprises with at least 51% Black ownership.

Skills Requirements

The service must be delivered by dual-specialized personnel. A qualified electrician must handle all electrical, control, and alternator-related diagnostics and repairs. A certified diesel mechanic must execute engine overhauls, fluid replacements, and mechanical inspections. Technicians must demonstrate proven experience with industrial diesel generator sets, proficiency in troubleshooting automated power systems, and the ability to interpret technical schematics. Personnel must also adhere strictly to occupational health and safety regulations and maintain accurate service documentation for audit purposes.

Clarification of Technical Terms

• Deep Sea Controller: An electronic management module that automates generator startup, shutdown, load sharing, and fault diagnostics, ensuring seamless power transfer during outages.
• AVR (Automatic Voltage Regulator): A device that stabilizes electrical output by continuously adjusting voltage fluctuations from the alternator to protect connected medical equipment.
• SBD Forms: Standardized South African government procurement declarations used to verify bidder identity, disclose conflicts of interest, claim preference points, and confirm compliance with national supply chain regulations.
• 80/20 Preference System: A procurement scoring methodology where 80 points are awarded based on price competitiveness and 20 points are reserved for specific socio-economic goals, prioritizing historically disadvantaged businesses to advance transformation targets.
