• Joint Venture agreement (if bidding as JV), signed by all parties

• Signatory must be authorised; if not a director/member/owner/shareholder, delegation of authority letter required.
• Validity period: 90 days after closing date.

Evaluation in three stages:

Stage 1 – Administrative compliance: verification of all returnable documents listed above. Failure on any compulsory item disqualifies.

Stage 2 – Mandatory requirements: bidder must provide 3 or more contactable reference letters for completed similar work (signed on company letterhead).

Stage 3 – Preferential point system (80/20):

• Price: 80 points (lowest acceptable price scores highest).
• Specific goals: 20 points, allocated as follows:

• B-BBEE status level: Level 1 = 8, Level 2 = 7, Level 3 = 6, Level 4 = 5, Level 5 = 4, Level 6 = 3, Level 7 = 2, Level 8 = 1, Non-compliant = 0. Evidence: valid certified B-BBEE certificate or sworn affidavit (EME/QSE) or CIPC B-BBEE certificate.

• EME and/or QSE: 2 points. Evidence: valid sworn affidavit or CIPC B-BBEE certificate.

• At least 51% women-owned: 2 points. Evidence: certified ID copies + proof of ownership (sworn affidavit, CIPC registration, etc.).

• At least 51% owned by people with disability: 2 points. Evidence: medical certificate with practice details + proof of ownership.

• At least 51% youth-owned: 2 points. Evidence: certified ID copies + proof of ownership.

• Local economic participation: City of Tshwane = 4 points, Gauteng = 2 points, National = 1 point. Evidence: municipal account statement or lease agreement.

Non-submission of specific-goal evidence scores zero for those goals but does not disqualify. Fraudulent claims lead to disqualification, cost recovery, contract cancellation, restriction from state business up to 10 years, and possible criminal prosecution.
