(a) After Kennedy Taylor submitted its variation claims the parties negotiated and settled them at meetings between Mr Holland on behalf of the agent of Crown and Mr Begbie and Mr Paneras and Mr Craige on behalf of Kennedy Taylor on specified dates in 1997.
(b) In the case of certain variations, the Crown witnesses had no recollection of agreeing the amount payable but agreement was to be inferred from the fact that the parties met and that Mr Holland, the Hudson Conway representative, noted a sum beside the variation on his list. This sum was paid and accepted by Kennedy Taylor.
(c) In the case of certain variation claims an analysis of them shows that they are duplications of other claims which have been agreed and paid.
(d) After Kennedy Taylor submitted its variation claims some were paid in full by Crown and the payments were accepted by Kennedy Taylor. Kennedy Taylor's present variation claims included enlarged claims which had previously been paid in this way. These enlarged claims should be dismissed because the earlier payment and acceptance determined this matter.
(e) After Kennedy Taylor submitted variation claims some were assessed by Crown or its consultants and the amount so assessed, being less than the amount claimed, was paid by Crown and accepted by Kennedy Taylor. Kennedy Taylor's present claims included claims which had previously been part paid in this way. Again, it is said that the payment and acceptance determined the entitlement of Kennedy Taylor.
(f) In August 1997 Mr Holland on behalf of Crown and Mr Begbie on behalf of Kennedy Taylor agreed that variations should be paid at rates set out in a certain price measurement document plus a 75% loading to compensate Kennedy Taylor for the difficulty of the work. Certain of the variation claims in which a greater difficulty factor loading was sought by Kennedy Taylor were reduced by Mr Holland to reflect the August 1997 agreement and Crown paid the reduced sum. Another change to the Kennedy Taylor variation claims which Mr Holland consistently and unilaterally adopted was the refusal to pay the sum of $50, $60 or $100 for drawings, manuals or references provided by Kennedy Taylor. He did this because he said these items were included in the original contract work and he had previously agreed this with Kennedy Taylor. These reductions, likewise, were not discussed and agreed with Kennedy Taylor as the claims were processed, but Crown consistently paid and Kennedy Taylor accepted the reduced payments and were accordingly bound by this.
