Construction is the single largest category of government tenders in South Africa. Public Works and its provincial counterparts maintain the state's 90,000-plus buildings; SANRAL and provincial roads departments build and maintain the road network; municipalities lay water, sewer and stormwater infrastructure; the IDT and education departments deliver schools and clinics; and housing programmes run continuously. On any working day the eTenders portal carries new building construction, civil engineering, refurbishment, maintenance and specialist works adverts across all nine provinces.

Every public construction tender specifies a minimum CIDB grading: a designation from 1 to 9 crossed with a works class such as GB (general building), CE (civil engineering), EP (electrical) or SB (specialist). A 1GB contractor can bid work up to R500,000; each step up roughly doubles the ceiling. Beyond CIDB, bidders need CSD registration, a SARS tax compliance pin, B-BBEE documentation, and often NHBRC registration for housing work, plus attendance at compulsory site briefings, which are near-universal on works contracts.
TenderFinder tracks every construction tender on the daily eTenders feed and lets you filter by province and keyword so you only see work matched to your grading and reach.

The advert states it. Small maintenance jobs may accept 1GB or 2GB; mid-size buildings need 5GB to 7GB; major infrastructure requires 8 or 9 in the relevant class. Bidding below the required grade leads to automatic disqualification.
