South Africa made AI disclosure mandatory in government bids

The South African Department of Public Works and Infrastructure issued a binding procurement circular on 11 August 2026, addressed to all government departments, municipalities, entities and public agencies procuring goods or services.

The stated purpose: to ensure transparency and accountability in government procurement, the Department requires all bidders to disclose use of generative AI, large language models, or algorithmic tools in tender preparation, so that decision-makers understand which proposals were AI-assisted and can evaluate bids accordingly.

This is a binding circular, not guidance. Procuring authorities are required to enforce it, and bidders who fail to disclose AI use are in non-compliance with tender requirements.

The circular applies to:

• All new tender processes launched after 1 September 2026.
• All active tenders published after 1 June 2026 that remain open for bids.
• All tenders with bids not yet evaluated as of 11 August 2026.

Bidders who submitted proposals before 11 August 2026 without disclosing AI use now face retroactive non-compliance. Procuring authorities must notify affected bidders and offer an opportunity to submit amended bids with AI disclosure, but an amended bid can be rejected if the disclosure materially changes its content, such as a cost estimate recalculated after disclosure.

Non-compliance carries serious consequences:

• Automatic tender rejection: a bid without AI disclosure is non-responsive and is disqualified outright, with no evaluation or score.
• Supplier blacklist: two or more non-disclosure instances within 24 months can restrict a supplier’s ability to bid for 12 to 24 months.
• Reputational harm: non-disclosure incidents are published in government tender record systems and become part of the supplier’s public procurement history.
• Potential legal consequences: non-disclosure of material information in a government bid can in some cases be challenged as tender fraud.

The circular defines AI use broadly. Disclosure is required for:

• Proposal drafting: AI used to draft, edit or refine tender responses.
• Technical design: AI used to design solutions or generate technical specifications.
• Cost modelling: AI used to estimate costs, pricing or project budgets.
• Data analysis: AI used to analyse tender requirements, market data or competitor intelligence.
• Scheduling and planning: AI used to generate project schedules, risk assessments or resource plans.

The disclosure requirement creates a competitive dynamic. If you disclose AI use and your competitors don’t, or disclose less, you’re at a disadvantage: the evaluator knows your proposal is AI-assisted but not whether your competitor’s is.

This creates a perverse incentive. Bidders who comply with disclosure signal transparency but risk evaluator bias against AI-assisted bids, while bidders who don’t disclose gain a competitive advantage by hiding AI use, at the cost of real penalty risk if it is later discovered.

In practice this means some evaluators will downweight AI-assisted proposals due to bias or concern about quality, while others will treat disclosure as neutral. The result is inconsistent evaluation across government departments.

If you’re a consultant or advisor helping clients prepare government bids, your engagement letters need to address four things:

• Disclosure obligation allocation: clarify who is responsible for disclosing AI use to government, the client or the consultant.
• Indemnity for consultant-side AI use: if you use AI tools to prepare the bid, indemnify the client against penalties if that use is not disclosed or is discovered after submission.
• Client obligation to disclose: the client must disclose all AI use including tools used by the consultant, with written evidence that the consultant informed them of it.
• Documentation of AI use: maintain a log of which tools and processes involved AI, for every tender, to support disclosure and protect both parties if later audited.
