Safety valve repair and testing services with calibration rig – open tender

Eskom requires suppliers to comply with its Contract and Contractor OHS Management standard (32-726) from project initiation through to post-contract review. The standard sets minimum OHS criteria for managing supplier compliance and conformity, applicable across Eskom Holdings SOC Ltd, its divisions, subsidiaries and entities where Eskom has controlling interest. Key phases covered: project initiation and briefing, concept and feasibility, design development, tender enquiry and evaluation, supplier registration, site mobilisation, contract execution and monitoring, contract completion and post-contract review. Work may be stopped, suspended or terminated for OHS non-compliance.

Closing date: 15 October 2026 at 10:00 (from tender record).

No briefing session or site visit dates are stated in the document. Bidders may be expected to conduct a site visit of the area where work will be executed before tendering, under Eskom supervision.

Eskom Holdings SOC Ltd is a State-Owned Company subject to regulatory compliance as applicable to Government. Generation Business Units are of strategic importance and most facilities are designated as National Key Points in terms of the National Key Point Act. The State Security Agency (SSA) advised Eskom to comply with the Minimum Information Security Standard (MISS) and implement a screening process to identify individuals who might pose a risk to operations. The screening process aims to protect the workforce, assets, and information. Security screening of contractors must take place before a contractor is allowed on site. The extent of access to sensitive information or critical plant areas is determined by the Scope of Work. The purpose of this document is to describe the criminal background check / screening requirements prior to contractor employees being granted access to National Key Points, and to map a standardized framework within Generation involving the requirement to be stipulated in procurement / tender processes and relevant documentation required prior to contract awarding. Relevant legislation includes the Minimum Information Security Standards (MISS), 1996, National Key Point Act, National Strategic Intelligence Act, and Protection of Critical Infrastructure Protection Act.

Eskom is committed to preventing all work-related injuries and maintaining a safe and healthy work environment in compliance with industry standards and legislative requirements. The Life-Saving Rules are safety rules that enforce zero tolerance for serious at-risk behaviours that have a high probability of causing disabilities or fatalities. These rules apply to all Eskom employees, agents, consultants, and contractors at all Eskom sites. Visitors must also respect and adhere to these rules and may be instructed to leave the premises if they refuse.

Contractors must comply with Eskom's Life-Saving Rules and associated disciplinary procedures. Violation of any Life-Saving Rule by a contractor employee results in immediate removal from site and disciplinary action. Contractor managers or supervisors who allow violations may have the contractor's activities suspended. Contractors must ensure all employees sign the Life-Saving Rule Acknowledgement Form (document 240-63942960).

Eskom's Life-Saving Rules apply to all Eskom employees, agents, consultants, and contractors at all Eskom sites. Visitors must also adhere to these rules and may be instructed to leave the premises if they refuse.

Five Life-Saving Rules:

• Rule 1 (Open, Isolate, Test, Earth, Bond, and/or Insulate Before Touch): No work on electrical networks, lines, or apparatus unless the worker is trained and authorised, has a valid permit to work where required, has conducted a pre-task risk assessment, follows the isolation and earthing requirements, the team leader has certified the apparatus safe, the environment is made safe, and appropriate PPE (including face shield and insulated gloves for low voltage work) is worn.
• Rule 2 (Hook Up at Heights): Work at height requires medical fitness, a pre-task risk assessment, appropriate training, being secured during ascent and descent, and using an Eskom-approved fall arrest system where applicable. Preference must be given to working at ground level.
• Rule 3 (Buckle Up): Seatbelts are mandatory for all drivers, operators, and passengers in vehicles or equipment used for Eskom business, on any road or parking lot, regardless of speed or direction.
• Rule 4 (Be Sober): No person under the influence of alcohol or drugs may enter or remain on an Eskom site, conduct Eskom business, or drive or operate vehicles or equipment for Eskom business.
• Rule 5 (Ensure That You Have a Permit to Work): No work without the required Permit to Work (PTW) where an authorisation limitation exists, governed by Plant Safety Regulations, Operating Regulations for High Voltage Systems (ORHVS), or any other activity requiring a permit. No plant is to be returned to service without cancellation of all permits, unless permission is granted for redundant systems.

Violation of a Life-Saving Rule is treated as serious misconduct and results in a disciplinary process in accordance with the Eskom Disciplinary Code and Procedure. Eskom takes a zero-tolerance stance. If a contractor manager or supervisor allows a violation, Eskom may suspend the contractor's activities while determining an appropriate sanction. The contractor must immediately remove the violating employee from site and initiate a disciplinary process within five working days, and must furnish Eskom with a copy of the sanction after the process.

Bidders must sign the Section 37(2) Agreement, acknowledging that they are employers with duties under the Occupational Health and Safety Act, 1993 (Act 85 of 1993), and agree to comply with the SHE specifications provided for the project.

Section 37(2) Agreement: The contractor/supplier must sign this agreement, acknowledging that it is an employer in its own right with duties under the Occupational Health and Safety Act, 1993 (Act 85 of 1993), and undertakes to ensure all work performed and machinery/plant used complies with the Act. The contractor has been provided with SHE specifications for the project/service and will comply with them. The SHE specifications constitute arrangements and procedures between the contractor and Eskom to ensure compliance with section 37(2) of the Act.
