Scope

The scope covers a broad range of civil, electrical, and environmental activities, including:

• Civil works such as foundation modifications, new foundation installations, earthworks, yard stone reinstatement, fencing, and building works at substations (Impala, Mersey, Tugela, Avon, Bloedrivier).
• Replacement and modification of high-voltage CTs and their foundations, including civil and structural support structures.
• Installation, testing, commissioning, and maintenance of electrical and mechanical equipment, with a focus on safety and environmental controls.
• Handling and disposal of hazardous and non-hazardous waste, including asbestos and PCB materials, in compliance with legal standards.
• Provision of site facilities such as offices, laydown areas, sanitation, safety signage, and environmental controls.
• Stakeholder engagement, community liaison, and socio-economic upliftment initiatives.
• Coordination of civil, electrical, safety, and environmental activities within project timelines.

Technical Requirements

The technical specifications mandate strict adherence to Eskom’s standards and detailed engineering drawings, including:

• Compliance with Eskom’s safety, health, environment, and quality standards, including ISO 9001.
• Development and implementation of Contract Quality Plans (CQP) and Inspection & Test Plans (ITP).
• Proper civil foundation modifications, including excavation, reinforcement, concrete casting, and structural support as per detailed drawings.
• Use of approved, calibrated lifting equipment, tools, and machinery in accordance with standards such as SANS, DMR, and CR.
• Effective management of hazardous materials, including asbestos and PCB waste, following legal and environmental disposal procedures.
• Implementation of comprehensive health, safety, and environmental management plans, including emergency response, fire safety, and site access controls.
• Regular inspections, audits, and monitoring to ensure ongoing compliance with safety and environmental standards.
• Proper documentation, including as-built drawings, safety certificates, and inspection records.

Skills and Competency Requirements

The tenderer must demonstrate the following skills and competencies:

• Qualified civil, electrical, and mechanical engineers with relevant experience in substation civil works, foundation modifications, and transformer support structures.
• Expertise in hazardous waste management, including asbestos and PCB disposal, aligned with legal and environmental standards.
• Proficiency in health and safety management, including risk assessments, method statements, and emergency procedures.
• Experience working within high-voltage substations, with knowledge of electrical safety regulations and permit systems.
• Certified personnel for operating lifting machinery, scaffolding, and other construction equipment (e.g., SANS, SACPCMP certifications).
• Capability to develop and implement environmental management plans focusing on pollution control, waste minimization, and site rehabilitation.
• Strong supervision, coordination, and communication skills to ensure project compliance, safety, and quality during all phases.
• Capacity to train and develop local SMMEs and community members, supporting socio-economic upliftment aligned with Eskom’s policies.

Overall Summary

This tender seeks to engage qualified contractors to undertake civil, electrical, and environmental works necessary for the safe replacement of high-risk CTs across multiple Eskom substations. The project emphasizes strict adherence to technical standards, safety protocols, environmental management, and skills development.
