Objectives

The primary objective is to successfully replace the existing 11 kV overhead line infrastructure at the Kriel Power Station. This project aims to improve grid reliability, ensure consistent power distribution across the facility, and maintain strict adherence to Eskom’s operational, safety, and quality standards over an eighteen-month contract period.

Scope

The scope covers the complete replacement of the designated medium-voltage overhead line within the Kriel Power Station premises. Deliverables include all necessary civil, structural, and electrical works required to decommission existing assets, erect new support structures, install conductors and insulation components, and commission the upgraded line. The contract duration is fixed at eighteen months, with all activities required to align with the employer’s project schedule and minimize disruption to ongoing power station operations.

Technical Requirements

• Contractors must hold a minimum Construction Industry Development Board (CIDB) grading of 7EP or higher.
• Full compliance with all basic tender requirements and preference scoring criteria is mandatory.
• Attendance at both a compulsory clarification meeting and a mandatory site walk is required; non-attendance results in immediate disqualification.
• Tenders must be submitted exclusively using the official documentation package issued by the employer. Electronic submissions or late deliveries will not be accepted.
• All execution must comply with South African national standards for electrical installations, occupational health and safety legislation, and Eskom’s technical specifications for medium-voltage infrastructure.

Skills Requirements

While not explicitly itemized in the tender notice, the mandated CIDB 7EP grading inherently requires a highly skilled workforce capable of managing complex medium-voltage electrical projects. Tenderers must demonstrate proven competency in project management, electrical engineering supervision, certified line construction, rigging and heavy equipment operation, and health and safety compliance specific to high-risk utility environments. Personnel must possess relevant trade certifications, industry experience, and the ability to coordinate safely within active power station zones.

Explanation of Specialized Terms

CIDB 7EP Grading: A South African contractor classification system that evaluates firms based on financial turnover, past performance, and technical capacity. Grade 7EP specifically authorizes contractors to execute electrical installation projects involving medium-voltage systems, requiring specialized expertise in power distribution networks and compliance with national construction standards.

11 kV Overhead Line: Refers to a medium-voltage power transmission network operating at 11,000 volts. These lines are widely used in industrial and utility facilities to distribute electricity across large sites, connecting transformers, switchgear, substations, and major electrical loads while maintaining safe clearance distances above ground level.
