Objectives

The primary objective is to design, construct, and commission a reliable medium voltage electrical supply network to support the operational functions of public ablution facilities (Ouboks) within the Colesberg area, under the jurisdiction of the Umsobomvu Local Municipality.

Scope of Work

The project covers the end-to-end delivery of an MV reticulation system specifically serving Oubok sites. Key activities include:

• Surveying, design, and procurement of MV underground cabling and associated infrastructure.
• Civil works comprising trenching, bedding, backfilling, and construction of cable pits, manholes, and connection chambers.
• Installation of protection relays, metering equipment, isolation switches, and municipal interface points.
• Testing, energisation, commissioning, and formal handover of all electrical installations.

Detailed drawings, bills of quantities, and specific performance metrics are provided in the official bid documentation.

Technical Requirements

Bidders must comply with the following technical and regulatory standards:

• Hold a valid Construction Industry Development Board (CIDB) registration at grading level 3PE.
• Ensure all works adhere to applicable South African National Standards (SANS), including SANS 10142-1 for electrical wiring and SANS 10288 for MV installations.
• Utilise municipality-approved, certified materials rated for outdoor and underground deployment.
• Implement comprehensive health, safety, environmental, and quality management plans aligned with OHS Act requirements.
• Submit method statements, test reports, and as-built documentation prior to final acceptance.

Skills and Experience Requirements

Contractors must demonstrate the following capabilities:

• Active CIDB 3PE registration, confirming financial and technical capacity to execute municipal-scale electrical projects.
• Employment of suitably registered personnel, including project managers, site agents, and Grade 1–3 licensed electricians.
• Proven experience in delivering similar MV reticulation or municipal infrastructure projects within the preceding five years.
• Skilled artisan teams proficient in both civil excavation/backfill operations and safe MV cable termination practices.

Explanation of Key Terms

MV Reticulation: Stands for Medium Voltage electrical distribution network, typically operating at 11kV. It is used to transmit power efficiently from municipal substations to multiple end-user locations across a defined service area.

Ouboks: A widely used regional term for publicly accessible toilet complexes. These facilities require dedicated, stable power connections to operate lighting, mechanical ventilation, water supply pumps, sewage lift stations, and security systems.

CIDB 3PE Grading: A contractor classification system administered by the Construction Industry Development Board. The numeral '3' indicates a maximum contract value capacity of R10 million, 'P' denotes plumbing, electrical, and mechanical engineering works, and 'E' confirms engineering capability. This grading validates that the contractor possesses adequate resources, expertise, and financial stability to deliver municipal infrastructure projects safely and to specification.
