Objectives

The primary objective is to ensure the continuous reliability, safety, and operational readiness of nine emergency standby generator sets at Grey’s Hospital through comprehensive annual preventive maintenance, rigorous performance testing, and detailed technical reporting. This safeguards uninterrupted power supply critical for healthcare operations and patient safety.

Scope of Work

The contractor will perform complete annual servicing across eight distinct generator locations (ranging from 150kVA to 1100kVA) and compile a consolidated safety file. Services encompass systematic inspection and maintenance of control panels, fuel systems, batteries, engine starters, solenoids, relays, and main alternators. Mandatory procedures include draining and replacing engine oil, changing all filters, adjusting fan belts, cleaning radiators and air passages, replacing air filters, inspecting turbochargers, checking exhaust systems, and performing pressure tests on the cooling system. Each unit must undergo simulated mains failure load testing for a minimum of twenty minutes, with precise logging of voltage, amperage, frequency, oil pressure, and temperature. Post-service requirements include thorough site cleaning, formal handover of removed components to facility management, obtaining explicit permission for mains power disconnection, and submitting individual technical reports along with cost quotations for any necessary post-service repairs.

Technical Requirements

• All work must comply with the South African Bureau of Standards (SABS) Codes of Practice, National Building Regulations, KZNPA General Electrical Specifications, and the Occupational Health and Safety Act 85 of 1993.
• Strict prohibition on using compressed air for cleaning electrical panels or alternator frames to prevent component damage.
• Cooling system must be pressure-tested to 150kPa using anti-freeze liquid and chemical inhibitor.
• Contractor assumes full responsibility for incidental masonry, patching, and painting resulting from electrical installations.
• All removed parts and equipment must remain on-site and be formally handed over to the Maintenance Manager.
• Service delivery must adhere to a pre-approved, site-specific safety plan and programme of works.

Skills and Qualification Requirements

• Minimum Construction Industry Development Board (CIDB) grading of 1EB or higher.
• Valid Letter of Good Standing issued by the Department of Labour.
• Certified trade test certificates demonstrating competency in both Electrician and Diesel Mechanic disciplines.
• Proven specialization in emergency generator maintenance as a core business activity, with prior approval from the provincial health department.
• Ability to develop, implement, and manage a comprehensive site-specific safety programme prior to mobilization.

Explanation of Unusual or Complicated Terms

• CIDB Grading: A South African classification system that assesses a contractor’s financial capacity, experience, and project execution capability. Grade 1EB indicates eligibility for smaller civil and electrical engineering projects.
• Letter of Good Standing: An official regulatory document confirming that a company complies with all statutory labour, tax, and employment legislation, ensuring no outstanding legal or compliance breaches.
• Trade Test Certificate: A formal qualification awarded after passing practical and theoretical examinations, verifying hands-on proficiency in a specific skilled trade.
• Simulated Mains Failure Load Test: A controlled procedure where utility power is deliberately disconnected to verify the generator’s automatic transfer switch response, runtime stability, and ability to sustain critical hospital loads without interruption.
• KZNPA Standard Preambles: Standardized contractual and technical guidelines issued by the KwaZulu-Natal Provincial Administration, governing construction and maintenance works within provincial facilities.
