Objectives

The primary objective of this tender is to supply, install, and commission standby generator sets for the Atlantis Labour Department building, ensuring reliable backup power supply. The project aims to provide fully operational diesel generator units with associated control systems, enclosures, and supporting infrastructure, compliant with relevant standards and regulations.

Scope

The scope includes:

• Supply of two generator sets: 100 kVA and 40 kVA, fully assembled and tested.
• Installation of generators inside weatherproof, soundproof enclosures with appropriate foundations and earthings.
• Connection of generators to existing electrical systems, including modifications to meters, distribution boards, and cabling.
• Provision of fuel tanks, piping, and filtration systems for continuous operation.
• Installation of control panels, alarms, remote monitoring, and automatic changeover systems.
• Site testing, commissioning, and documentation.
• Provision of a 1-year maintenance plan and spare parts.

Technical Requirements

The technical specifications include:

• Generator sets must be self-contained, with automatic start/stop, capable of accepting full load within 15 seconds.
• Engines: diesel, compression ignition, rated for continuous operation, with de-rating for site altitude (1641m) and temperature (max 28°C).
• Alternators: brushless, self-excited, capable of 110% overload for 1 hour, with voltage regulation within ±5%.
• Enclosures: IP65 weatherproof, soundproof, constructed from stainless steel (3CR12 or grade 316), with adequate ventilation and access.
• Control systems: modular, with alarms for high temperature, low oil pressure, low fuel, over/under voltage, frequency, and remote monitoring capabilities.
• Fuel system: integral tank with capacity for 24 hours operation, filtration, water separator, and fire protection features.
• Electrical: connection to existing distribution, with modifications to meters and cabling as specified.
• Compliance: with SANS 8528, IEC 60947, local regulations, and environmental standards.

Skills Requirements

The tenderer must demonstrate:

• Proven experience in supplying and installing standby generator systems of similar capacity.
• Qualified personnel: engineers, technicians, and electricians with relevant certifications and experience.
• Capability to perform site assessments, modifications, and testing to meet technical specifications.
• Ability to prepare comprehensive operating and maintenance manuals, and provide training if required.
• Compliance with health, safety, and environmental regulations, including preparation of a site-specific safety plan.
• Provision of after-sales support, including a 12-month free maintenance period and spare parts availability.

Summary

The project encompasses the supply, installation, testing, and commissioning of two diesel standby generators with associated infrastructure, control systems, and documentation, ensuring reliable backup power for the Atlantis Labour Department building, in accordance with technical standards and safety regulations.
