An investigation shows that top construction companies fixed state and other contracts worth billions of rands.
City Press reports that affidavits detail a decades-long, formal kickback and price-fixing racket that allegedly involved prominent names in the industry.
The newspaper says at least 11 affidavits were made by executives from Stefanutti Stocks --one of the country's biggest construction firms -- to the Hawks serious economic offences investigator and the National Prosecuting Authority.
The statements were also handed to the Competition Commission for its probe into construction industry tender-rigging, thought to involve contracts worth at least R30 billion.
According to the affidavits, the projects "fixed" include the National Stadium in Soweto, the Coega development project in the Eastern Cape, Green Point soccer stadium in Cape Town, the Nelson Mandela Bridge in Johannesburg, and the Gautrain.
