"Budgeted cost" for design 4: the Council's argument
32 The Council argued that the selection of $1.5 million as a figure for the budgeted cost was unreliable, and the figure which should have been selected was $665,767 (being the estimate for the cost of the "café and water element" made by a firm of quantity surveyors, Page Kirkland Partnership, before 15 November 1995). This involved a small degree of generosity by the Council, which could have pressed the figure of $455,441 which that firm estimated for the water element alone on 30 November 1995.
33 The argument of the Council drew attention to the following matters.
34 On 13 January 1992 the Council wrote to the plaintiff inviting him to participate in a limited design competition. The letter said that the design competition was to be for part of the works to be undertaken outside the actual site of Chifley Tower. It also said that the undertaking of those works had been a requirement of the development approval. The letter enclosed a "Brief and Conditions" for the competition. That document contained the following passages (Blue 2/310D-H and 311K):
"Generally, the items and works to be included in the design solution for this competition are left to the discretion of the entrant. It should be noted that the Architect of The Chifley Tower project has submitted a design solution in the form of a Pavilion in stone, details of which are included herewith. No other Pavilions will be considered as design solutions.
Therefore if work such as sculpture, fountains, landscape etc are to be included as part of the proposed design solution and if specialist sub-contractors are to be employed in the implementation of these designs at a later date, then an appropriate artist/expert in those fields should be nominated.
…
As a guide to entrants, it is advised that the estimated cost of the project architects proposed solution (a pavilion) is $1.45 million."
35 The plaintiff did not in fact accept the invitation to compete in the competition.
36 On 23 June 1992 the Project Director of the Chifley Tower wrote to the Council noting that the Council had decided not to proceed with the construction of any of the entries in the competition. It said that while previously he had advised a cost of about $1.4 million, because of the requirement to use certain pavers carrying an extra cost:
"I believe we should consider the sculpture contribution matter in light of this circumstance.
This being the case, I believe it is reasonable for us to offer you an amount of $1,050,000 contribution to the sculpture fund" (Blue 2/316P-R).
37 On 9 July 1992 the Council wrote to the Project Director of the Chifley Tower. The letter said that the Council had resolved to take no further action on the competition entries. It said, in item (d), that the Council had also resolved to request the owner to contribute to the Council a sum equal to the estimated cost of what was described as "the original Rotunda" (an idea preceding the competition), "to be placed in a 'Chifley Square Civic Improvement Fund' on the understanding that Council would be committed to expend the funds held in that area". The letter said that the Council had also resolved that a proportion of that fund would be dedicated for a future study for a design for Chifley Square as a whole. It continued:
"With regard to item (d) Council will be pleased to accept your offer of $1,050,000 made in your letter dated 23rd June 1992, to provide Council with funds to expend in Chifley Square, a proportion of which will be spent developing a master plan for the area.
Your cheque should be made payable to the following trust fund account:
'SCC, Public Art, Chifley Square'
The cheque should be clearly marked as set out above.
The tunnel contribution of $2 million must be paid into a separate account:
'SCC, Civic/Pedestrian Improvement, Chifley Square'
You will appreciate that the two contributions must be paid into separate accounts to ensure the funds are used only for the specific purpose nominated" (Blue 2/322V-323H).
38 On 19 August 1992 one of the developers of Chifley Square, Baygate Pty Ltd, was given a receipt for the payment of $1,050,000 as a "Contribution to Public Art, Chifley Square": Blue 2/248. As the trial judge recorded, this was part of a total amount of $3,050,000 which the developers contributed to the Council to be used for the development of Chifley Square as a public space: Red 2/89R. The $1,050,000 was kept as a "Public Art Fund" and the $2 million was kept as a "Pedestrian Improvement Fund" (Blue 2/335-R-W).
39 The trial judge found that by late October 1994 the Council had approved a budget for 1994-1995 of $1,150,000 on Chifley Square and an additional budget of approximately $1,200,000 to be spent "on a public art component" (Red 2/91V; Blue 2/366L).
40 On 3 November 1994, according to the trial judge's findings, the plaintiff attended a meeting at the Council, where the Council's Visual Arts Officer, Sally Couacaud, told him that a design concept for Chifley Square had been prepared which included a café cut into the site and that water was to be included as an artwork. She asked the plaintiff if he would be interested in designing the water element (Red 2/95P-T).
41 On 23 November 1994 the plaintiff attended another meeting at the Council. A proposal involving a triangular café with still water on its flat roof and water flowing down its sloped northern glass wall was explained to the plaintiff by Mr Williams, the author of the concept. The plaintiff said he was interested in doing the work provided he had design freedom. A fixed fee of $50,000 was agreed (Red 2/96D-N). The plaintiff was told by Mr Williams that the overall budget for the project (i.e. the works to be funded from the $1.05 million and the $2 million) was $2.6 million. Mr Williams said in cross-examination that it was "regarded as an essential element to the whole project that there be an element of public art in the Square", including a commemoration of the late J B Chifley (Red 2/98C; Black 2/352S-V).
42 On 15 May 1995 Hassell Pty Ltd wrote to the plaintiff to say it had been appointed project manager. The letter said (Blue 3/463M-N):
"Consequently we accept your fee proposed of $50,000 for the design and documentation of the 'Waterfall'. Your fee for preparing mock-ups and prototypes is still to be formally accepted by council so we will deal with this separately."
43 In May 1995 Hassell Pty Ltd prepared a document entitled "Chifley Square Redesign Concept Review". That contained various sketch designs (Blue 3/482-485), and recommended (486) option 2 (483). It also contained cost estimates by Page Kirkland Partnership. Those estimates totalled $2,617,157.31. That figure was arrived at as follows. A cost of $1,612,056 was allowed for "paving" and $512,260 was allowed for "café" (which, pursuant to Mr Williams' explanation to the plaintiff on 23 November 1994, included the water feature the plaintiff was to design). That totalled $2,124,316. An allowance of 10 percent for certain contingencies brought the total to $2,336,747.60. A further allowance of 12 percent for Preliminaries and Profit brought a grand total of $2,617,157.31 which corresponds with the figure of approximately $2.6 million given to the plaintiff on 23 November 1994 (Blue 3/503). Page Kirkland Partnership offered a break-up of the $512,260 figure for the café. Among the elements were "Roof" ($250,000) which included $100,000 for "Water curtain" (Blue 3/505Y), and "Hydraulic Services" ($35,000) (Blue 3/507V).
44 It is convenient to interpolate that the Council's submission was that in the period of design 4, the highest figure ever allowed by Page Kirkland Partnership for "café and water element" was $665,767, and that figure, part of Estimate No 3, probably provided on 21 September 1995, was the highest budget figure for the water feature. Another relevant set of figures was given by Page Kirkland Partnership as part of Estimate No 5, namely "Café" $328,048.20, and "Water Element" $455,441. It was part of the Council's argument that a conclusion that the budgeted cost for that part of the artwork in Chifley Square for which the plaintiff was to be responsible, against the background of events before the design 4 period and during the design 4 period, was as much as $1.5 million was wholly unrealistic. As will be seen, the trial judge found that it must have been plain to the Council and to Hassell Pty Ltd that design 4 "was likely to be a far more expensive project than the original concept", i.e. design 1. A question is whether the Council appreciated a fifteenfold increase as distinct from a fourfold or sixfold increase.
45 On some date after 7 June 1995, Mr Maher of Hassell Pty Ltd asked the plaintiff for any cost information about his proposed design option. Mr Maher said the conversation proceeded as follows (Red 2/108G-K):
"Plaintiff: 'I cannot give you any cost information. Once I have developed the prototypes I will be able to determine the flow rates and thereafter the size of the pumps and tanks necessary. Then I can give you an estimate of feasibility as well as cost.'
Mr Maher: 'Bob, we are concerned that we must have some certainty as to the cost of the fountain element. As you know we currently only have an allowance of around $500,000 for the café and water feature, including at this stage $100,000 allowance for the water feature. If the fountain exceeds this amount then we could only proceed with it if we were able to find savings elsewhere in the project.'"
