6 A dispute arose between the parties during the performance of the contract works by the respondent. This led to the giving, by the respondent, of a notice of dispute by way of a letter from its solicitors dated 22 May 1998. That letter summarised a number of points which were then in dispute between the parties. It seems, from the letter, that the appellant contended that the respondent had breached its obligation under the contract to proceed with due expedition and without delay. The appellant had extended, by three weeks, the date which had been fixed for practical completion and it seemingly threatened to claim liquidated damages in respect of the respondent's failure to meet the extended deadline. The respondent, on the other hand, claimed to be entitled to have the time for practical completion extended by seven weeks and to recover the costs of the delay, which, it said, necessitated that extension, from the appellant. It had, in that respect, made a claim for payment of $74,118.94 which had been rejected by the appellant. There appears then also to have been a dispute as to the appellant's entitlement to remove roadworks originally contracted to the respondent and to assign those works to another contractor without the prior written consent of the respondent. Finally, the respondent had lodged with the appellant its Progress Claim No 3 and that claim had been rejected by the Superintendent. The respondent claimed to be entitled to payment.
