Price points calculated using formula Ps = 80(1 - (Pt - Pmin)/Pmin) where Pt = price of tender under consideration, Pmin = price of lowest acceptable tender. Specific goals points per 80/20 system: B-BBEE Status Level 1 = 5 points, Level 2 = 4.5, Level 3 = 4, Level 4 = 3, Level 5 = 2, Level 6 = 0.5, Level 7 = 0.3, Level 8 = 0.1; Black youth majority-owned entities = 5 points; Black women majority-owned entities = 5 points; Company majority owned by people with disabilities = 5 points; Non-compliant contributor = 0 points. Failure to submit proof for specific goals means points not claimed. Organ of state may require substantiation of claims at any time. No minimum functionality or technical threshold stated; evaluation appears to be price and specific goals only.
