The Public Financial Management Act sets out the other general rules which government must follow in issuing tenders, and should be read in conjunction with the National Treasury Regulations.
Other guiding policies include:
At national level, preferential factors include:
The points formula used is described in WCBD 6.1, which must be completed (see how tenders are awarded).
For tenders under R500 000, an "80/20" points system is used (this means that tenders are evaluated 80% on price and 20% on points for factors such as historically disadvantaged individual status, ownership by women, etc). For tenders over R500 000, a "90/10" system is used.
Not all of the preferential factors will apply for every tender. The tender documents should indicate which preferential factors apply to your tender.
Each local government body has its own procurement policy, which is guided by national legislation such as the Municipal Finance Management Act, as well as the Local Government Capital Asset Management Guidelines.
