Objectives

The primary objective is to upgrade the outdated fire detection cabling infrastructure at Rand Water’s Rietvlei facility. This upgrade ensures full compliance with South African National Standards (SANS), maintains critical life-safety system functionality during emergencies, and guarantees adequate evacuation time for building occupants.

Scope of Work

The appointed contractor will execute the following deliverables:

• Remove all existing fire detection cabling across the Rietvlei building.
• Supply and install PH30-rated cabling throughout general building areas.
• Supply and install PH120-rated cabling specifically within the server room.
• Wire and connect the new cabling to all relevant fire detection system components.
• Restore and make good all ceilings and floor voids opened during installation.
• Conduct comprehensive testing, programming, and commissioning of the detection systems.
• Issue a valid Certificate of Compliance (COC) upon successful completion.

All activities must be performed in occupied environments without disrupting ongoing operations or damaging existing furniture and equipment.

Technical Requirements

• Cable Specifications: PH30 cables must maintain circuit integrity for 30 minutes during a fire, while PH120 cables require 120 minutes. Both must operate at 300/500V and withstand minimum temperatures of 950°C per BS 6387 category CWZ.
• Regulatory Compliance: All materials, installations, and workmanship must strictly adhere to SANS 10139, SANS 1411-1, and SANS 10142-1.
• Safety & Site Protocols: Pre-work submissions must include a comprehensive safety file, PPE registers, health and safety inspection checklists, scaffolding compliance documentation (SANS 10085), competency certificates, legal appointments, and signed safety policies. All work must comply with the Occupational Health and Safety Act and Rand Water’s site-specific SHEQ regulations.
• Contractual Framework: The project operates under the FIDIC Short Form of Contract with localized amendments. Bidders must hold a minimum CIDB contractor grading of 3EB. Evaluation utilizes an 80/20 preferential procurement system (80 points for price, 20 points for B-BBEE status).

Skills and Resource Requirements

• Personnel: Bidders must submit an organizational chart detailing staff dedicated to this project. Mandatory key personnel include one Master Electrician (with a valid ECB number), technicians (holding Wireman’s licenses), and Electrical Artisans (with verified trade test results). CVs for all listed personnel are required.
• Equipment & Plant: A detailed inventory of owned, leased, or hired machinery, vehicles, tools, and software must be provided, confirming immediate availability and maintenance readiness.
• Experience & Planning: Demonstrated experience in similar fire detection or low-voltage cabling projects is required, supported by verifiable client references. Bidders must submit a resource-loaded project programme featuring Gantt charts, Level 2 scheduling, and monthly cash flow projections aligned with contractual milestones.
• Risk & Insurance Management: Contractors must fulfill specified insurance obligations, including Contract Works, Public Liability, Contractor’s Equipment, Workers Compensation, and Professional Indemnity cover, as outlined in the employer’s insurance manual.

Notes on Unusual or Complicated Terms

• PH30/PH120 Cables: Specialized fire-resistant cables engineered to maintain electrical circuit integrity during a fire for 30 or 120 minutes respectively. They are critical for life-safety systems, ensuring fire alarms and detection networks remain operational long enough for safe evacuation.
• Certificate of Compliance (COC): A legally mandated document certifying that all electrical and fire detection installations meet South African regulatory standards. Payment and official sign-off are contingent upon its issuance.
• 80/20 Preference Point System: A South African public procurement scoring mechanism where 80% of adjudication points are awarded based on competitive pricing, and 20% are allocated according to the bidder’s Broad-Based Black Economic Empowerment (B-BBEE) contribution level.
• FIDIC Short Form Contract: An internationally recognized construction contract template adapted with localized amendments governing dispute resolution, insurance, variations, and payment terms specific to this engagement.
