(a) Details of work at Lorne, showing the value of each component of the work, the extent to which each component had been completed, and the amount due accordingly in respect of that work.
(b) Details of work at Apollo Bay showing the value of each component of the work, the extent to which each component had been completed, and the amount due accordingly in respect of that work.
(c) Variations to work at Lorne and Apollo Bay, showing every component of the variations, the value of each variation, the extent to which each variation had been completed and the amount claimed accordingly.
(d) A summary of each of the above amounts, a note of amounts previously paid, and a calculation of the balance currently claimed.
This level of detail, so it was submitted, is prima facie sufficient evidence of the amount due. It remained open to the superintendent to seek further information. Despite his ability to do so, the superintendent did not do so. The evidence which had been referred to by the appellant, so he submitted, did not seek any particular information of any component of any Progress Claim. Furthermore, it was contended that the superintendent had failed to seek any information about components of the claims even though he had that opportunity. He pointed to the fact that Progress Claim 11 had included details of 57 "variation components" since the beginning of the contract; that Progress Claim 12 had added details of variation components 58 to 71; that Progress Claim 13 had added a variation component No. 72 and that Progress Claim 14 had added variation component No.73. Progress Claim 15 showed no changes from Progress Claim 14. These variation components and each Progress Claim, so Mr. Burnside contended, are very specific; and to a qualified person intimately involved in supervising a project are likely to be self-explanatory. The superintendent was, as Mr. Burnside contended, intimately involved with the project because "that is his job". He pointed out that Progress Claim 12 was provided to the superintendent on 27 February 1998; and that there was no evidence of the superintendent seeking any information about any of the added variation components; and that the same was true of later Progress Claims. The sub-contract provided, so it was submitted, for a Progress Claim every month and for certification within 14 days. This system of claim and certification, it was submitted, would be unworkable in practice if the superintendent was entitled to ignore Progress Claims, not seek information if he actually needed it, and then assert that the information was insufficient.
