Durban construction company in multibillion-rand tender battle with road agency By Nathan Craig Share Durban - Construction giant Aqua Transport and Plant Hire claims that the SA National Roads Agency (Sanral) deliberately blocked their bids for tenders worth billions, and had the road infrastructure agency gave those contracts to them, government would have saved R400 million. Aqua instituted court action after Sanral’s board of directors banned them for six months and the three tenders, each worth about R1.5 billion, were subsequently awarded to Raubex Construction and Rumdel Construction. In December, they successfully interdicted the work from proceeding on the contracts and the trial is set to begin on May 21.
