IDC invited contractors to tender for the external upgrade of its head office in Sandton through a two-phase process. Trencon submitted its RFP timeously, while Basil Read submitted 14 minutes late. IDC condoned the late submission. Trencon submitted the lowest bid price of R133,508,788 and stated its price would remain fixed provided the Works started on the scheduled date. When asked about a delayed site handover, Trencon indicated it would charge 0.6% monthly escalation (R315,000 excluding VAT). Basil Read's price would remain firm despite delays. Trencon scored the highest points on price and BEE rating and was recommended by the BEC and PC. However, concerns were raised about whether the additional cost for delayed handover contravened tender conditions. Exco obtained a legal opinion suggesting Trencon's bid was not firm and fixed. Exco decided that Trencon's bid was non-responsive because it amended its price after closing, rendering it invalid. Exco declined to award the tender to Trencon and instead awarded it to Basil Read.
