MSC Depots (appellant) contracted WK Construction (respondent) on 15 September 2006 to construct a container depot in Despatch, Eastern Cape, using a JBCC series 2000 standard building agreement. The depot was to withstand heavy loads from reach stackers (45-ton capacity machines) and store containers weighing about 25 tons. Construction commenced on 4 August 2005 and was virtually completed by 17 January 2006. An interim payment certificate for R827,392.03 was issued on 31 March 2006 and approved by the appellant on 25 April 2006. However, in May 2006, deflections were noticed in the paving before payment was made. The appellant's regional manager Georgiev stopped payment on 4 May 2006, assuming construction faults. After meetings and correspondence, the respondent began remedial work but was instructed to stop on 22 May 2006 as the method was deemed inadequate. On 14 August 2006, the respondent gave notice of intention to cancel the contract due to the appellant's alleged breaches, including failure to pay the certified amount and preventing the principal agent from exercising independent judgment. The respondent cancelled the contract on 29 August 2006. The appellant denied breach and claimed the respondent repudiated the contract.
