(d) Builders' OH& Profits @ 10%."
106 The defendant challenges the Referee's "preference" in respect of each if the items (a), (b), (c) and (d) above. It was submitted that the Court should not adopt the report, insofar as it suggests that such additional items have been assessed by the Referee. I note that Items (a) and (b) were not included in the joint Scott Schedule.
107 Mr Robertson for the defendant contended that, in respect of the items "Supervisor for the plaintiff" and "reserve for unknowns", none of the parties' experts or the parties themselves contended for either or these items. In such circumstances, it was contended (Defendant's Outline of Submissions, paragraph 40):-
"… The Referee was not entitled to invent new heads of claim in the absence of affording the parties an opportunity to make submissions and lead evidence regarding whether those heads of claim should be allowed."
108 Mr Darvall, quite properly in the circumstances, did not make any submissions in support of conclusions expressed by the Referee in relation to them.
109 In respect of Items (c) and (d) above, the first, "Preliminaries" (Item 156 in the joint Scott Schedule), was allowed by the Referee at 12.5% ($48,008). The report noted that the defendant's expert had integrated or included preliminaries in the rates adopted by him. The Referee's opinion is expressed in these terms, in respect of Item 156:-
"I prefer the PEs' allowance of preliminaries (either wholly or partly) for the reasons given in the text of My Report."
110 In respect of Item (d) above (numbered Item 158 in the joint Scott Schedule), the Referee noted, "Builders' Overheads and Profit 10%". The opinion is expressed in terms:-
"I prefer PEs' allowance for OH&P for the reasons given in the text of My Report."
111 In relation to the item "Preliminaries" (numbered Item 156 in the Joint Scott Schedule), it was contended, again, that, as in respect of Items 5, 39, 102, 108 and 109, the Referee's report suffered from a lack of reasons. In this respect, it was contended that whilst the report did provide reasons as to why "preliminaries for the head contractor should be included in the total cost", the report did not provide any reasons as to why the figure of 12.5% was adopted instead of a figure such as 8% or 10%.
112 In the body of the report (paragraph 58(c)), it was stated that, in the conclave, the parties discussed the use of and the quantum of head contractors' preliminaries. It was noted:-
"They agreed that if they were to be included, that the rate should be 8 to 12.5% of the total of the sub-contractors' prices."
113 It is clear that there was no agreement that the appropriate allowance in this case was 12.5%, that is, the top of the range figure. Why the Referee elected to adopt that particular percentage figure is not stated in the report.
114 It is clear, in these circumstances, that the opinion of the report adopting 12.5% for preliminaries was an opinion unsupported by reasons.
115 For the reasons I have earlier set out, the report should not be adopted in respect of this item.
116 In relation to the item, "Builders' OH & Profits at 10%", the Referee dealt with that matter in paragraph 61 of his report. He noted there that the plaintiff's experts allowed 10% of the payment by the head contractor for the sub-contractors and preliminaries as overhead and profit. He stated that, in his experience, for renovation work, OH & P frequently was 15% and, at time, as high as 25%.
117 The basis upon which the allowance was made is set out in paragraph 63 of the report entitled "My Preference - 8". In that paragraph, however, the Referee stated his preference for the "Plaintiff's allowance for OH & S", but for reasons for stated in (a), (b), (c) and (d). However, those paragraphs simply identify the tasks that would be required. They did not explain why the Referee preferred the figure of 10%.
118 In the submissions for the defendant in relation to this item, it was observed that the report did not explain why the fact that a head contractor might have to "pay for marketing" or effect "payment for CPB training …" bore on the question as to the quantum of the liability under the repair and maintenance provisions of the relevant lease.
119 I do not consider that the matters set out in the report, including, in particular, paragraph 63 constitute reasons or an explanation for the adoption of the particular percentage figure adopted for builders' overheads and profits.
120 No doubt, the figure would vary according to the nature of the project and the nature and number of the sub-contractors required to undertake specific particular aspects of the work constituting the project.
121 In the circumstances and for reasons earlier stated, on the question of the obligation to provide reasons, the report does not, in relation to this item, satisfy the requisite requirement and tests.
122 I, accordingly, am of the opinion that the report should not be adopted in relation to preliminaries or overhead and profits.
