Tender Summary: Nhlangano Phase 3 Electrification

Objectives

The primary objective is to deliver complete electrical infrastructure for 72 new residential connections in the Nhlangano rural settlement. The project aims to construct, test, commission, and hand over a fully operational medium and low voltage network, while ensuring all customer data is accurately captured and uploaded for official energization and municipal reporting.

Scope of Work

The successful contractor will be responsible for the end-to-end execution of the electrification project, including:

• Supply, transport, storage, erection, alignment, and commissioning of all electrical infrastructure.
• Installation of approximately 216 medium voltage wooden poles, overhead distribution lines, transformers, insulators, stays, and surge diverters.
• Construction of low voltage networks using insulated aerial bundled conductors, pole-mounted distribution boxes, fused disconnect switches, and earthing systems.
• Execution of 72 house connections utilizing smart split meters, passive base units, and data concentrators.
• Dismantling and removal of surplus or decommissioned materials, and vegetation clearing along power line servitudes.
• Provision of site facilities, security, community liaison, and strict compliance with Expanded Public Works Programme (EPWP) labour guidelines.

Technical Requirements

Bidders must meet stringent technical and regulatory standards, including:

• Grading & Registration: Minimum CIDB contractor grading of 3EP PE or higher, with valid tax clearance, Central Supplier Database registration, and municipal rates clearance.
• Standards Compliance: All works must adhere to Eskom Distribution Standards, SANS specifications, and the Occupational Health and Safety Act Construction Regulations 2003.
• Safety & Planning: Submission of a detailed Health and Safety Plan prior to commencement. A sample installation must be completed and approved before full-scale construction begins.
• Materials & Testing: Use of approved materials (e.g., CCA-treated poles, ABC conductors). Soil resistivity testing is mandatory, with earth resistance capped at 10 ohms. Comprehensive testing and commissioning per Eskom protocols are required.
• Documentation & Handover: Submission of marked-up as-built drawings in Microstation/DWG format and accurate PCS files for system registration. Final handover requires energization, Clerk of Works verification, and Field Services sign-off.
• Financial & Contractual: Fixed pricing with no adjustments. A 10% retention applies (half refunded at completion, half after a 12-month defects liability period). A performance guarantee equivalent to 10% of the tender sum is mandatory. Contract duration is six months.

Skills and Personnel Requirements

Contractors must demonstrate proven capability and resource readiness through:

• Key Personnel: Appointment of a Contract Manager, Site Supervisor, at least one Eskom-accredited MV/LV permit holder, four accredited linesmen, a crane truck operator, and a qualified Health and Safety Officer.
• Accreditation: All live-line workers must hold valid Eskom MV/LV Lines and Cables training accreditation.
• Local Labour Preference: Priority must be given to hiring unskilled workers and subcontractors from the immediate local community.
• Experience & Capacity: Proof of successfully executed similar electrification projects, validated plant and equipment ownership/lease agreements, and evidence of sufficient working capital (bank statements, overdraft facility, or supplier credit letters).
• Compliance Documentation: Submission of BBBEE certificates/affidavits, COIDA Letter of Good Standing, Skills Development Levy certificate, and UIF registration.

PCS Files: Customer Pre-connection Service electronic files containing precise GPS coordinates, meter serial numbers, and installation data required by Eskom for network registration and billing activation.

Co-Daptix: Eskom’s proprietary customer management software used to capture, validate, and upload connection data for operational integration.

ABC Conductors: Aerial Bundled Conductors, which are insulated multi-core cables strung overhead without traditional bare-wire spacing, enhancing safety and reducing right-of-way clearance requirements.

CIDB 3EP PE: Construction Industry Development Board grading indicating technical competence in electrical engineering projects with a defined minimum annual turnover threshold.

EPWP: Expanded Public Works Programme, a national policy mandating labour-intensive construction methods to create temporary employment opportunities for unemployed individuals.
