Fire safety works
10The referee referred to the evidence of the witnesses who were called in relation to the fire safety works. The witnesses who gave testimonial evidence were Mr Villanti, Mr Thorburn, Mr Shipway and Mr Watkins. Mr Villanti was the proprietor of a lot in the development. His evidence was to the effect that at a particular time, he walked through levels 8 and 9 and made observations of the state of completion. Although Mr Villanti was not a builder, the referee found that his evidence was credible, being the evidence of "a careful and thoughtful witness" (R202). The referee found support, in the detail of Mr Villanti's evidence, for the conclusions that he reached.
11Mr Thorburn was an architect. He or his firm had been engaged by Avri as the project architect. Mr Thorburn was the supervisor. Mr Thorburn's evidence does not appear to have occupied a great deal of time in the referee's deliberative processes.
12Mr Shipway was Avri's project manager. The referee was not impressed by Mr Shipway as a witness. I think it is fair to say that in general, the referee was not prepared to act on Mr Shipway's evidence except to the extent that it was corroborated by contemporaneous documents. In this context, particularly bearing in mind the convoluted history to which I have referred and the passage of time, the referee's preference for contemporaneous documents as an accurate source of information is to be understood and approved.
13Mr Watkins was, at the time, the managing director of Lipman. The referee did not find his evidence to be helpful, in particular because it was conclusory. It appeared to the referee that Mr Watkins was giving evidence not from direct knowledge but, rather, at second hand.
14There was a measure of common ground in the way that the parties approached the fire safety issues. For example, it was common ground that in early 1999, Avri decided to redesign the layout of levels 8 and 9. It asked Lipman to quote. No agreement was reached for the performance of the works as redesigned. Nonetheless, Mr Thorburn, the architect and superintendent, instructed Lipman to proceed with levels 8 and 9 works including sprinklers and mechanical services work. It was common ground, and the referee found at R154, that the fire safety defects alleged by the Owners Corporation relate principally to fire dampers that form part of the mechanical services work - part of the work in respect of which Mr Thorburn instructed Lipman to proceed.
15The referee noted that Mr Shipway accepted that the instruction "was unqualified in any way by reference to the layout changes proposed for levels 8, 9 and 9 mezzanine" (R155). The referee set out (and obviously accepted) a passage from Mr Shipway's evidence, which included what appears to have been an acknowledgment by Mr Shipway that mechanical services work on levels 8 and 9 was to continue as originally planned despite the proposed layout changes. The referee found accordingly.
16That seems to me to be a finding of very considerable significance. It was not challenged. Nor could it be.
17In relation to levels 8 and 9, (there is no need to keep on referring to the level 9 mezzanine) fire safety works, the complaint made by Lipman was that the referee had not referred to what it said was cogent evidence of a change in Lipman's scope of work. That change was said to have occurred in August 1999, and to have arisen from two documents to which I will refer. I might add, at this stage, that although the referee did not expressly refer to those documents, he conducted an exhaustive analysis of the evidence, on the basis of which he concluded that the original scope of work in relation to levels 8 and 9 mechanical services had been completed whilst Lipman was still on site, and before St Hilliers came there. That analysis included reference to work done and invoices rendered by Lipman's subcontractor for the relevant services, a company known as Protair.
18Mr Goldstein of counsel, for Lipman, referred to the letters which, he said, showed a reduction in Lipman's scope of work. The first was written by Avri to Lipman on 12 August 1999. Omitting formal parts, it states as follows:
We confirm that you are currently proceeding to complete the works on CP1 to CP3, Levels 1 to 7 and plant rooms, together with the base works to Levels 8 and 9, as soon as possible. The aim is to complete these works to allow the Sydney City Council to issue a certificate and for Avri to take possession of the building at the time to attempt to meet its obligations to purchasers of the units of Levels 1 to 7. We understand you are currently programming to complete this work in mid-September.
We agree with you adopting this approach provided that you have in place necessary arrangements for the relevant services Trade Contractors to complete the remaining services work to Levels 8 and 9. This work would be completed under the terms of the existing Trade Contracts, however, Avri is prepared to supervise this work directly (or through its consultants) rather than require Lipman to attend to this work.
Whilst understanding the Lipman does not wish to undertake the balance of the works on levels 8 and 9, which is mainly provisional work under the terms of our existing Agreement, we have agreed on the following approaches:
a) Lipman to submit a proposal with respect to the above work on levels 8 and 9; or
b) Avri to attend to this work directly and no payment will be made to Lipman for these works.
We thus invite you to submit your proposal to us as soon as possible which we will discuss with you upon receipt.
19The second document to which Mr Goldstein referred was Lipman's response of 30 August 1999. Again omitting formal parts, it states as follows:
We refer to your letter dated 12/08/99, in particular some anomalies between statements in the letter and actual fact.
We accept your first paragraph except that we are aiming for completion by the end of September, not the middle.
Secondly we are aiming only to complete the essential services to levels 8 and 9, not necessarily the 'base works'. Having said this, we will complete additional and non essential works, should the costs be agreed and subject to the works not effecting the delivery programme of 30/09/99.
With respect to the issue of remaining works we must add that Lipman P/L are more than happy to complete the project in its entirety, what we were unable to accept was to proceed with the works without approval. We have however already submitted a proposal for level 8 and 9, of which we have received no feedback.
Should Avri Investments P/L decide that they would prefer to complete the remainder of the works themselves, we had advised that we would not object to Avri approaching the contractors to complete the works directly contracted to Avri. This would however have to be treated as a separate agreement which excluded Lipman P/L from any liability or input.
We trust this clarifies the situation.
20What is notable about those documents is that they do not define in any precise way the work (the base work, or essential services) that Lipman was to complete, nor indeed the work (the balance of work of levels 8 and 9) that Lipman was not required to complete. Some assistance can perhaps be obtained from the document, or proposal, referred to in the fourth paragraph of Lipman's response. That is a document of 24 June 1999. For level 8, it proposes a price of $747,712 for various works, of which some $75,960 relates to fire and mechanical services work. For level 9, it proposes a total price of $1,339,694, of which some $78,719 relates to fire and mechanical services work. That may be taken to indicate that the outstanding, or unperformed, portion, or "balance", of those works on those levels was relatively insignificant compared to the totality of work required.
21One might have thought that the CMA would throw some light on the topic. However, as I have noted, by some masterpiece of drafting ingenuity, it managed to include the subject works in both the GMP works (schedule 18) and the provisional works (schedule 19). Thus, no assistance is obtained from the CMA by Avri's classification of the balance of the works (in its letter of 12 August 1999) as "mainly provisional".
22Mr Shipway gave evidence in a statement as to what he regarded as "the essential services" to be. The referee did not refer to this. In part, no doubt, that followed because he did not refer to the two documents in question. In part, perhaps, it reflected his lack of enthusiasm for Mr Shipway as a reliable witness.
23Mr JJ Young of counsel, for the Owners Corporation, referred to expert evidence given by a Mr Hoyle. Mr Hoyle is an expert in fire safety. He said that his expertise includes "fire dampers and essential services". However, I do not think that it is legitimate to rely on the evidence of an expert, given some time after the relevant documents were exchanged, as an aid to the construction of those documents. I might add that equally I do not think it is legitimate to rely on Mr Shipway's evidence, even were it to be accepted, for the same purpose. There was no submission that any of this aspect of Mr Hoyle's or Mr Shipway's evidence reflected something notorious in the industry at the relevant time.
24Mr Goldstein's complaint - and it has force - is that, by failing to refer to evidence as to the change in the scope of Lipman's obligations under the CMA, the referee failed to consider properly the way in which Lipman put its case on this issue. Mr Bambagiotti of counsel, for BIGCORP, adopted Mr Goldstein's submissions in this and all other respects.
25Certainly, it would have been desirable for the referee to give consideration to the two documents in question, and to any other documents that, in his view, bore on the topic, with a view to completing his analysis of the relevant events, if only to indicate why, in his view, they were irrelevant. However his analysis proceeded in a slightly different way. The result of that analysis, I think, was to make it unnecessary for him to consider whether there had been any agreement as to a revised scope of works. On that approach, if I have understood the referee correctly, his omission to deal with the two documents may reflect no more than a particular application of the approach outlined by him at R17, to which I have referred.
26As I have foreshadowed, the approach taken by the referee was to examine the evidence to see what in fact was the work, in relation to fire safety on levels 8 and 9, actually done by Lipman (more accurately by its subcontractor Protair). The referee appears to have reasoned that if Lipman did the work, the implied statutory warranties would be attracted. That approach must be correct, I think. Accordingly, I do not think that it is necessary to consider in detail the reasoning of the Court of Appeal in a case on which Mr Young relied, Building Insurers' Guarantee Corporation v The Owners - SP 60848 [2012] NSWCA 375. I do however note that in that case, Bergin CJ in Eq (at [51] and Sackville AJA at [72]) in effect said,
the implied statutory warranties are attracted to work that was done (or agreed to be done), not to work that falls outside the scope of the contract. I add that Macfarlan JA agreed with both their Honours.
27This case is in some respects factually the obverse to that on which Mr Goldstein based this aspect of his submissions. The question that the referee asked himself was: what was the work that Lipman did? He answered that question by saying, among other things, that it included the fire safety work on levels 8 and 9 that was found to be defective and that required repair. Since there was no basis for concluding that Lipman did it other than as a builder under the CMA, that completed the referee's investigation.
28If the two documents of August 1999 were crystal clear as to what work had been taken out of Lipman's scope, it would have been incumbent upon the referee to deal with them. But they were not crystal clear; they were not even clear in any usual sense of that word. Avri said in effect that it understood that Lipman was to proceed with, among other things, "the base works to levels eight and nine". Lipman said that it was "aiming only to complete the essential services" to those levels, "not necessarily the base works."
29If there were admissible evidence that identified what might be regarded as "base works", or evidence which identified what the parties themselves had in mind as "essential services" (apart from Mr Shipway's conclusory statements on the topic), I was not referred to it. And I repeat that evidence given after the event is not of assistance; evidence as to what the parties had in contemplation at the time they wrote their letters, and evidence as to what each might have understood to be the subject of the other's proposal, could be in a different category. But if there were any such evidence then, as I have said, I have not been taken to it.
30In those circumstances, I am not in a position to conclude that the letters were so clear that the referee was required to give detailed consideration to them on this topic. When one looks at the totality of the evidence which is summarised in the report, it paints a different picture.
31First of all, as the referee noted, there was the redesign. There was then the instruction to proceed with the levels 8 and 9 works. That instruction was agreed to be one which related to those works as originally tendered, unqualified in any way by reference to the layout changes. It thus included whatever was the content of the fire safety works under the original scope of works.
32It is common ground that the fire safety works included the installation of some dampers. I should note that Protair appears to have considered that the revised scope of works would require it to install additional dampers, for which it had not quoted. But nothing seems to me to turn on that, because it has not been suggested that the defective dampers are any other than those the subject of the original scope of works.
33Then, the referee analysed the contemporaneous documents. He placed particular weight on a Protair payment claim made in June 1999, under which Protair claimed the full value of its contract and, in addition, a number of variations. As the referee said at R164, Protair seems to have thought that its obligations were complete. And again, as the referee said at R165, Lipman appears to have taken the same view, because it passed on that claim to Avri for payment. The referee expressly rejected Mr Shipway's attempts to talk down the import of those documents.
34There was other evidence, to which the referee referred, which appeared to him to corroborate the proposition that the fire safety work, the subject of the original quotation on levels 8 and 9, had been completed. That included Mr Villanti's evidence to which I have referred already, and the evidence of a review undertaken by the mechanical services consultant retained by Avri.
35That consultant prepared a report in October 1999 which noted that the work was about 98 per cent complete. Although that document, and other documents to which I have referred and to which the referee referred, relate to a period after the exchange of correspondence in August 1999, the evidence is clear that Lipman did not leave site until some time later, and St Hilliers did not come on site until, probably, early 2000.
36In all the circumstances, the referee said that he was "comfortably satisfied that Lipman performed the mechanical services work, including the fire safety installation and dampers, the subject of the defects claimed...on levels 8 and 9" (R176).
37In my view, there was ample evidence to justify the referee in coming to that conclusion. There was, in addition, other, although less significant, corroborative material to which the referee then referred.
38In those circumstances, and given as I have said the obscure and unhelpful drafting of both the CMA and the letters exchanged in August 1999, I am not persuaded that the referee's omission to deal with the two letters shows any basis for doubting the validity of his conclusions, let alone that the matter should go back to him for further inquiry and report.
