NV Properties (Pty) Ltd (employer) and Radon Projects (Pty) Ltd (contractor) concluded a contract for the construction of the East London Convention Centre using the JBCC Principal Building Agreement 4th ed March 2004. The agreed date for practical completion was 17 October 2008. During construction, the contractor submitted various claims to the principal agent under clause 29 for revisions to the date for practical completion due to delays. Some claims were granted, extending the date to 9 March 2009. The project reached practical completion on 14 December 2009, resulting in penalties of approximately R6 million. After practical completion, the contractor submitted a 'consolidated claim' comprising revised versions of earlier claims based on information that came to hand after completion. The principal agent failed to respond. The contractor requested a determination under clause 40.1, which was not provided. An arbitrator was appointed. The employer applied to the High Court contending the arbitrator had no jurisdiction over most claims. Da Silva AJ granted the order, and the contractor appealed.
