Objectives

The primary objective of this tender is the replacement of the backup diesel generator at Efaye Clinic, ensuring a reliable power supply through the installation of a new, compliant generator system. The project aims to rig out the existing damaged generator, supply and install a new generator with associated civil, electrical, and control systems, and ensure proper testing, commissioning, and certification.

Scope

The scope of work includes:

• Removal and safe disconnection of the existing damaged 31.3 kVA generator.
• Supply and installation of a new 35 kVA, 3-phase, 50Hz backup diesel generator within an enclosed canopy.
• Construction of a suitable plinth capable of supporting the generator and diesel tank.
• Provision and installation of electrical connections, control panels, exhaust systems, and ventilation ducting.
• Supply and installation of a self-bunded fuel tank with automatic and manual filling systems.
• Provision of surge, fire, earthing, and lightning protection measures.
• Testing, commissioning, and certification of the entire electrical and mechanical installation.
• Provision of as-built drawings, manuals, and staff training.

Technical Requirements

The technical specifications include:

• Generator capacity of 40 kVA, with compliance to SANS 8528 standards and local manufacturing preference.
• Engine type: multi-cylinder, four-stroke, direct injection, compression ignition, suitable for diesel fuel.
• Engine cooling: water-cooled with heavy-duty radiator, thermostats, sensors, and exhaust silencing.
• Alternator: genuine, locally supported, 3-phase, 4-wire, rated at 40 kVA, with automatic voltage regulation within ±2.5%.
• Control panel: robust, dustproof, with programmable control systems (Deep Sea DSE 7320 or equivalent), alarms, and remote monitoring capability via WebNet.
• Fuel system: integral base tank with 72-hour capacity, automatic fill, and level alarms; optional external bulk tank for extended operation.
• Electrical installation: compliant with SANS 10142, including conduits, wiring, earthing, and switchgear.
• Mechanical installation: civil works for plinth, civil civil engineering, ventilation, and exhaust ducting.
• Testing: factory and site acceptance tests, with detailed documentation and certification.

Skills Requirements

The tenderer must demonstrate:

• Proven experience in installing and commissioning standby generator systems, with at least five (5) recent projects of similar scope within the past three (3) years.
• Qualified personnel, including:
• Trade-tested electricians or electrical technicians with relevant experience in generator installation and electrical systems.
• Trade-tested diesel mechanics or mechanical technicians with experience in engine and generator commissioning.
• Qualified riggers with valid trade certificates and experience in heavy equipment handling.
• Engineers or certified structural engineers for civil works and plinth design.
• Capability to provide ongoing maintenance and support services post-installation.
• Ability to produce detailed project management plans, including risk assessments, timelines, and quality assurance procedures.
• Compliance with all relevant South African standards, legislation, and safety regulations.

Summary

The successful tenderer must deliver a fully functional, compliant backup generator system, including mechanical, electrical, civil, and control components, with qualified personnel capable of executing all aspects of the project from removal to commissioning and handover, supported by relevant experience and certifications.
