Ramaphosa last week signed a proclamation authorising the corruption-fighting unit to investigate problems at Sita, including allegations of maladministration and corruption related to the procurement of a turnkey asset management software solution.
"The SIU will assess whether the procurement process adhered to national treasury guidelines or whether it was tainted by irregularities, lack of transparency or wasteful expenditure. Additionally, the investigation will examine any unlawful or improper conduct by Sita employees, suppliers or other entities involved in the contract," the SIU said.
The investigation will focus on a period between July 2017 and May 2025, including any relevant conduct before or after this timeframe. Evidence of criminal conduct uncovered during the investigation will be referred to the National Prosecuting Authority.
"Sita welcomes the recent proclamation by Ramaphosa authorising the SIU to probe the 2017 procurement process involving a turnkey software asset management solution and integrated logistics support services," Sita said in a statement.
"This investigation - targeting a contract awarded following adjudication related to six service providers - represents an important step in our ongoing mission to rebuild public trust and ensure full compliance with ethical and legislative procurement standards," the agency said.
