The board of the South African National Roads Agency Limited (Sanral) has instructed Sanral management to readvertise and award the R17.47-billion in tenders the board cancelled earlier in May, citing “material irregularities”, within the next four months. Speaking at a media conference in Centurion on Monday, Sanral board chairperson Themba Mhambi added that the board would recruit an independent public institution with infrastructure expertise to assist with the process to advertise and adjudicate the tenders, and to make a recommendation to the board on the winning bidders.
