**55 In our view each of those findings was open on the evidence. In so far as the ultimate financing of the project is concerned his Honour analysed the evidence given by two finance experts, Mr Roberts and Mr Franzese. He concluded that if the matter had been diligently and competently pursued it was probable that Burstone would have obtained finance of $35 million from an Australian bank. It is true that his Honour considered that, to obtain traditional bank finance, the parties would each have to make equity contributions of between $3 million and $5.5 million. But his Honour concluded that, taking into account the funds which subsequently became available in May 2000, Burstone would have had the capacity to make such contribution by about mid May of 2000. That finding was also open on the evidence. Likewise, the finding of his Honour that, as of October 1999, the project was still in the town planning phase, a matter on which Reading relied, has to be considered in the context of the findings that drawings, feasibilities and programs which were appropriate at that stage had been finalised. Furthermore, the evidence before his Honour was that, although Reading had anticipated a difficult process involving objectors, a favourable final decision by December 1999 was predicted. In fact, Burstone succeeded in obtaining town planning approval in mid November 1999. True it is that, as Reading pointed out, his Honour regarded the 40 per cent speciality leasing pre-commitment requirement as an area of uncertainty. Nevertheless, the evidence of Mr Snow, a land economist, was that the 40 per cent pre-commitment requirement was a common requirement and could have been achieved within five to six months. This evidence was supported by that of Mr Close, the expert valuer called by Reading, who said in cross-examination that meeting the 40 per cent pre-commitment 'would be reasonable'. His Honour accepted that evidence and concluded that the 40 per cent special leasing pre-commitment requirement was usual and achievable within a five to six month period. In so far as the construction costs were concerned, the evidence of Mr Beattie, the managing director of Davis Langdon Australia Pty Ltd, the quantity surveyor for the project, was that the various cost plans produced represented the accurate cost estimates based upon the material which was then available, although he conceded that, as of October 1999, that material was limited. It was in this context that his Honour considered that the estimate of construction costs should include a contingency allowance of up to 10 per cent.
