Tender Summary: Service Fire Suppression Systems at Rand Water Zuikerbosch and Eikenhof

Objectives

The primary objective is to maintain, repair, and periodically service fire suppression and fire detection systems at two Rand Water facilities. The tender seeks a qualified supplier to ensure continuous system reliability, regulatory compliance, and rapid response to component failures across specified operational sites.

Scope of Work

The project is divided into two location-specific bids:

• Zuikerbosch (Bid 10416868): Supply and installation of 150 mm flow switches, test valves, gauge cocks, water motor alarm gongs, and gate valves. Replacement of six painted sprinkler heads, two incorrect heads, and one damaged head. Draining and refilling of two sprinkler systems. Servicing of one P&G unit and three gas cylinders. Quarterly fire suppression services (23 units per quarter) and fire detection services (10 units per quarter) for four quarters. Preparation of a site safety file.
• Eikenhof (Bid 10415935): Repair of fire suppression systems in three engine rooms. Quarterly fire suppression services (one unit per quarter) and fire detection services (one unit per quarter) for four quarters. Servicing of three gas cylinders. Preparation of a site safety file.

Technical Requirements

Bidders must demonstrate capability in:

• Installation, testing, and commissioning of wet sprinkler networks, including flow switches, alarm gongs, and isolation/control valves.
• Accurate replacement and calibration of sprinkler heads according to hazard classification and environmental exposure.
• Controlled system draining, flushing, and refilling procedures that preserve pipe integrity and prevent contamination.
• Maintenance, pressure verification, and certification of gas-based suppression cylinders.
• Inspection, functional testing, and troubleshooting of fire detection panels and associated sensors.
• Compilation and ongoing maintenance of compliance-ready safety documentation aligned with occupational safety standards.

Skills Requirements

Although not explicitly detailed in the provided documentation, the scope inherently requires personnel with:

• Recognised trade qualifications or certifications in fire protection technology/engineering.
• Practical experience with mechanical and electrical fire suppression and detection systems.
• Competence in hydraulic system testing, valve assembly calibration, and pressure retention verification.
• Working knowledge of South African fire safety regulations and compliance documentation protocols.
• Ability to operate safely within active industrial and water treatment environments while minimising operational disruption.

Explanation of Technical Terms

P&G: Refers to a Pressure Gauge or Pump Group assembly used to monitor water pressure and flow status within fire suppression piping networks.

Safety File: A mandatory compliance dossier containing system schematics, maintenance logs, inspection certificates, risk assessments, and statutory compliance records required by occupational health and fire safety authorities.

Quarterly Services: Recurring maintenance visits scheduled every three months to inspect, test, and certify system functionality throughout the annual contract period.

Gas Cylinder Servicing: The inspection, weight verification, pressure testing, and recertification of clean agent or carbon dioxide fire suppression cylinders to ensure they meet performance and safety standards.
