25. It is unclear why Mrs Beamish has chosen to rely on the estimates proved by Mr Setford, as qualified by Mr Heber, when she apparently had access to all of the invoices relating to the works carried out by Mr Heber. A witness statement of Graham Joseph, accountant for Mr Beamish's business, setting out a reconciliation of the invoices, apparently applicable to the works carried out at the subject property by Mr Heber, and payments made against those invoices was filed ("the account reconciliation"). These invoices total $393,179.09. The account reconciliation identifies the creditor, the date and amount of the invoice.
26. In his report dated 17 May 2005 Mr Irwin confirms that in preparing his report and estimates he 'relied on Mr Setford's reports, Mr Heber's documentation, and any clarification provided verbally by Mr Setford and Mr Heber' and 'In preparing my estimates I adopted, where appropriate, the invoiced cost of the work. For works for which I was unable to rely on invoices I measured the work involved and priced it at what I considered to be appropriate rates for the work which was executed in the latter months of 2003 and the early months of 2004.'
27. When advised on day five of the hearing that Mrs Beamish would no longer be relying on Mr Irwin's estimates I was told it was because they referred to the actual cost of the works from which it was difficult to extrapolate the value of any betterment. However, I note that in relation to some items the invoices referred to in Mr Irwin's report are for an amount which is less than Mr Setford's estimate - for instance in relation to the cost of replacement of the stairs. Mr Setford has allowed $5,000.00 for a new staircase, whereas Mr Irwin's report refers to an invoice to 'supply and fix staircase' in the sum of $3,250.00. The primary difference between the preparation of the estimates by Mr Irwin and Mr Setford appears to be that Mr Setford has prepared his estimate on the scope of works he identified as being necessary when he inspected the property in August 2003, and Mr Irwin prepared his estimates with the benefit of Mr Heber's advice as to the works which had actually been undertaken, and by reference to the relevant invoices. Whilst Mr Irwin's total estimate might have been significantly higher than Mr Setford's estimate and the quantum of Mrs Beamish's amended claim, the estimate for rectification of certain items was less. Where Mr Irwin's estimate is significantly less it is to be preferred.
28. Inexplicably, neither Mr Joseph nor Mr Irwin were called to give evidence. Further, having regard to the provisions of s97 of the VCAT Act to '...act fairly and according to the substantial merits of the case' I am of the view I should have regard to Mr Irwin's report insofar as it provides clarification of the actual cost of the works. It was not until day five of the hearing that there was any indication that they would not be called as witnesses. I have no alternative but to draw a negative inference from Mrs Beamish's failure to call them as witnesses (Jones v Dunkel (1959) 101 CLR 298). Irrespective of the findings I may make in relation to Mr Rosvolls' responsibility for the defective works, there is no doubt that Mrs Beamish's conduct of this proceeding has caused unnecessary delays and adjournments to the hearing.
29. Although Mr Rosvoll filed an expert report from Mr Gordon which included estimates for the cost of rectification works, I have not considered them. Mr Gordon was not called to give evidence and those estimates have not been tested. Surprisingly Mr Rosvoll did not cross examine Mr Setford on his estimate of 11 November 2005, preferring to cross examine on his earlier estimate of 1 November 2004 on which Mrs Beamish had indicated she was not relying. This was notwithstanding the adjournment granted to Mr Rosvoll to enable him to consider the revised estimates, discuss them with Mr Gordon and file and serve any answering material. I accept that the estimates on which Mrs Beamish relies are therefore not challenged but refer to my earlier comments in relation to Mr Irwin's estimate and the failure to call him and Mr Joseph as witnesses.
