Objectives

The primary objective is to replace a decommissioned 60kVA backup diesel generator at Phatheni Clinic with a fully integrated, containerized standby power system. This ensures uninterrupted electricity supply for critical clinical operations while complying with provincial health infrastructure and electrical safety standards.

Scope of Work

• Rig out and safely disconnect the existing damaged generator.
• Supply and install a canopy-enclosed 60kVA, three-phase, 50Hz backup diesel generator.
• Install 35mm² four-core ECC copper cabling from generator terminals to the changeover panel.
• Supply and fit a generator control panel with protection equipment, terminations, and ancillary components.
• Provide and install exhaust ducting, ventilation louvres, and a reinforced concrete plinth.
• Implement surge protection, fire detection/fighting equipment, earthing, and lightning protection systems.
• Conduct factory acceptance and site testing, commission the installation, and obtain an Electrical Certificate of Compliance.
• Deliver operator training, comprehensive manuals, as-built drawings, and fill the fuel tank with 1,200 litres of diesel.
• Execute provisional scope items including fire safety installation, earth mat construction, and electrical load datalogging.

Technical Requirements

• Generator Performance: Must deliver 60kVA at 0.8 power factor, achieving 60% load within approximately 15 seconds and full load shortly thereafter.
• Engine & Alternator: Water-cooled, direct-injection diesel engine with electronic governing; revolving-field alternator with Class H insulation, brushless excitation, and ±2.5% voltage regulation.
• Fuel System: Self-bunded base tank combined with a bulk tank, enabling 72 hours of continuous full-load operation, complete with automatic refilling and low-level alarms.
• Control & Monitoring: Programmable Automatic Mains Failure (AMF) controller with remote WebNet/GPS/GSM connectivity for live diagnostics and operational tracking.
• Compliance & Testing: Full adherence to SANS 10142, SANS 8528, and BS 5514 standards. Mandatory factory and site load bank testing, soil resistivity analysis, and provision of a Certificate of Compliance.
• Warranty & Maintenance: Twelve-month guarantee covering defects and workmanship, including bi-annual preventive servicing throughout the maintenance period.

Skills and Qualification Requirements

• Contractor Grading: Minimum CIDB grading of 2EB.
• Key Personnel Certifications: Certified trade test certificates for a diesel mechanic/millwright, electrician/millwright, rigger, and wireman’s license. Engineers/technicians must hold ECSA professional registration.
• Proven Experience: Submission of award letters and signed completion certificates demonstrating company and key personnel experience in similar generator installations over the past five years.
• Operational Capacity: Documented proof of staffing and resources to execute after-hours or weekend installations with minimal clinical disruption.
• Manufacturer Accreditation: Exclusive partnership with genuine OEM manufacturers offering local 24-hour support and in-house maintenance facilities. Grey market or copied equipment is strictly prohibited.

Explanation of Unusual or Complicated Terms

• CIDB 2EB: A Construction Industry Development Board grading indicating contractor competency to execute medium-scale electrical engineering and building services projects.
• AMF (Automatic Mains Failure): An automated switching system that detects municipal power loss, starts the generator, transfers the electrical load, and reverts to mains supply once restored.
• Self-Bunded Tank: A double-walled fuel storage container designed to capture and contain any leaks from the inner tank, preventing environmental contamination and meeting safety regulations.
• WebNet/GPS/GSM Integration: A remote monitoring platform utilizing cellular networks and satellite positioning to enable real-time status tracking, fault alerts, and operational control from off-site locations.
• SANS & BS Standards: Mandatory South African National Standards (SANS) and British Standards (BS) governing electrical wiring safety, generator set performance ratings, and component quality.
