The applicable preference point system is the 80/20 system (for requirements with a Rand value of up to R50 million, all applicable taxes included). Points are awarded for Price (80 points) and Specific Goals (20 points), totalling 100 points. Price points are calculated using the formula: Ps = 80(1 − (Pt − Pmin)/Pmin), where Ps = points scored for price, Pt = price of the tender under consideration, and Pmin = price of the lowest acceptable tender. Failure to submit proof or documentation required to claim points for specific goals means those points are not claimed.
