Transnet issued a Request for Proposal (RFP) on 29 November 2018 for the manufacture, supply and installation of high security fencing at its City Deep, Kascon and Kaserne premises. The RFP required a tender sample of 400mm x 400mm that met specifications including that panels and fixtures be hot dip galvanized to SANS121:2011 and wire diameter be minimum 3mm. Tipp-Con submitted a tender sample on 21 January 2019 that was not hot dip galvanized but disclosed this, explaining that the actual panels would be hot dip galvanized. On 30 January 2019, Transnet's evaluation committee unanimously rated Tipp-Con's tender as substantively responsive. On 10 April 2019, Tipp-Con submitted its best and final offer of R34,371,970.15, stating it was offering 4mm wire diameter. On 11 July 2019, Transnet's Head Office Acquisition Council approved the award to Tipp-Con. On 7 August 2019, Transnet notified Tipp-Con of its appointment. On 13 September 2019, representatives inspected full-scale samples at supplier facilities and selected a fence with 3mm horizontal and 4mm vertical wire diameter. The contract (NEC 3 Engineering and Construction Contract) was signed on 30 October 2019. Installation commenced 21 October 2019. On 26 November 2019, Transnet requested test results. A dispute arose regarding fence specifications, which was referred to adjudication. On 7 August 2020, the adjudicator ruled in favor of Tipp-Con, finding the fence was installed according to contractual specification and was hot dip galvanized, with any deviation from 3mm wire diameter being de minimis. On 7 October 2020, Transnet launched a review application in the Gauteng High Court, Pretoria. The high court dismissed the review on grounds of unreasonable delay.
