• Low value: R30 000 up to R50 million — 80/20 preference point system.
• High value: above R50 million — 90/10 preference point system.

Risk is assessed from the technical specification or scope of work: high risk affects Eskom core business directly (e.g. transformers, cables, conveyor belts); low risk does not (e.g. cleaning, security, landscaping).

Quality requirements may be exempted for:

• All LPOs approved by cost centre managers.
• Transactions above the LPO limit but below R1 million that are low complexity and low risk.

Exemption requires the Exemption Certificate (240-144723833) completed by the business unit SQM representative and accepted by the relevant manager.

Scope: selection of supplier quality requirements for Eskom tenders, RFQs and contracts, covering both pre-award and post-award stages.

Selection is driven by:

• Contract value (low or high under the PPPFA thresholds).
• Risk to Eskom core business, based on the technical specification or scope of work.
• Complexity and duration of the contract.

Quality requirements are defined in the QM 58 specification and must be included in the tender or enquiry documents.

For complex transactions involving installation, manufacturing, testing or commissioning, a Quality Control Plan (QCP) or Inspection and Test Plan (ITP) is required regardless of category.

Exemption is normally considered only for off-the-shelf items requiring no modification, maintenance or customisation to Eskom specifications or regulatory requirements.

Quality requirements are defined in the QM 58 specification and must be included in the tender or enquiry documents.

• 240-109253302: Quality Control Plan or Inspection and Test Plan (QCP/ITP).
• 240-126469599: Method Statement.

A QCP or ITP is required for complex transactions involving installation, manufacturing, testing or commissioning, regardless of category.

Exemption from quality requirements:

• All LPOs approved by cost centre managers are exempt.
• Transactions above the LPO limit but below R1 million that are low complexity and low risk may be exempted.
• Exemption requires the Exemption Certificate (240-144723833) completed by the business unit SQM representative and accepted by the relevant manager.
• Exemption is normally considered only for off-the-shelf items requiring no modification, maintenance or customisation to Eskom specifications or regulatory requirements.

No pricing schedule is included. Contract value determines the applicable preference point system:

• R30 000 up to R50 million: 80/20 preference point system.
• Above R50 million: 90/10 preference point system.

Value and risk together determine the quality category (Category 1 to 4) and the quality requirements that apply.

Value thresholds determining the preference point system:

• R30 000 up to R50 million: 80/20 preference point system.
• Above R50 million: 90/10 preference point system.

Quality requirements may be exempted for transactions above the LPO limit but below R1 million that are low complexity and low risk.

No bid security, guarantee, retention or payment terms are stated in this guideline.

ISO 9001 certification:

• Mandatory for Category 1 (high risk, high value) transactions; no award without a valid certificate.
• Not mandatory for Category 2 where the scope does not require it.

Quality management system:

• Category 3 (high risk, low value) requires an established and documented QMS.

Returnable quality documents:

B-BBEE, CSD registration, tax compliance and CIDB grading are not addressed in this guideline.

Quality requirements are selected using the Supplier Quality Requirements Selection Criteria, which places each transaction into one of four categories by value and risk:

• Category 1 (high risk, high value): ISO 9001 certification is mandatory and a condition of award.
• Category 2 (low risk, high value): ISO 9001 is not mandatory where the scope does not require it.
• Category 3 (high risk, low value): an established and documented quality management system is required.
• Category 4 (low risk, low value): non-technical, non-network or off-the-shelf products or services.

Value bands (PPPFA):

• Low value: R30 000 up to R50 million — 80/20 preference point system.
• High value: above R50 million — 90/10 preference point system.

Risk bands:

• Low risk: does not affect Eskom core processes (e.g. cleaning, security, landscaping).
• High risk: directly affects Eskom core processes (e.g. transformers, cables, conveyor belts).

Complex transactions involving installation, manufacturing, testing or commissioning require a QCP or ITP regardless of category.

Eskom requires the collection, assessment, repair, refurbishment, assembly, testing and delivery of milling plant seal air fan runners at Duvha Power Station over a six-month period. The work is tendered as a single contract for the whole scope. The contract is based on the NEC form of contract.
