Objectives

The primary objective of this tender is to procure a qualified service provider for the routine maintenance and overhaul of emergency backup generators across multiple healthcare facilities. Ensuring the immediate operational readiness of these units is essential to guarantee uninterrupted power supply for critical medical services during municipal electricity failures.

Scope of Work

The contract encompasses major preventive maintenance services for emergency generators stationed at five designated clinics. The scope includes:

• Complete drainage and replacement of engine oil with specified grade lubricants.
• Thorough flushing of engines and radiators using approved chemical cleaning agents.
• Removal and installation of new air, oil, and fuel filters.
• Refilling cooling systems with high-purity engine coolant.
• Inspection and functional testing of drive belts, diesel pumps, fuel injectors, crankcase heaters, and coolant sight glasses.
• Verification and calibration of electrical control panels, automatic transfer switches, digital monitoring controllers, automatic voltage regulators, and alternators.
• Supply of all labour, travel expenses, and replacement parts as itemised per clinic location.

Technical Requirements

Bidders must demonstrate strict adherence to the following technical specifications:

• Equipment Specifications: Each clinic operates a distinct generator model and capacity (ranging from 20 KVA to 100 KVA Deutz engines). Maintenance procedures must align precisely with the manufacturer's technical parameters for each specific unit.
• Quality Standards: All workmanship, materials, and certification documentation must comply with recognised national standards, including SABS, SANS, SANAS, and SAQCC.
• Parts & Materials: Only new, genuine replacement parts matching the specified part numbers and quantities may be utilised. Expired, refurbished, or second-hand products are strictly prohibited.
• Procurement Scoring: The evaluation utilises a statutory 80/20 preference point system, allocating 80 points to price competitiveness and 20 points to specific socio-economic transformation goals.

Clarification of specialised terms: An automatic changeover switch is a safety device that automatically transfers electrical load from the municipal grid to the backup generator during power outages. An AVR (Automatic Voltage Regulator) continuously monitors and stabilises the generator's output voltage to protect sensitive hospital equipment from surges. The 80/20 system is a South African public procurement scoring model where the lowest compliant bid receives maximum price points, while remaining points reward designated transformation targets (specifically companies with at least 51% black ownership).

Skills and Competency Requirements

To qualify, bidders must prove technical competence and operational reliability through the following criteria:

• Specialised Personnel: All electrical diagnostics and repairs must be executed by a competent, registered electrician, while mechanical and engine-related tasks must be performed by a certified diesel mechanic.
• Proven Track Record: Submission of at least two verifiable trade references demonstrating successful completion of similar generator maintenance contracts, accompanied by proof of payment and client contact details.
• Regulatory Compliance: Valid Central Supplier Database (CSD) registration, confirmed SARS tax clearance status, and a valid BBBEE status certificate or sworn affidavit.
• Performance Integrity: Bidders must declare no history of contract defaults, fraudulent bidding practices, or disciplinary sanctions. Any misrepresentation or failure to disclose conflicts of interest will result in immediate disqualification.
