MISLEADING CONDUCT IN RELATION TO DESIGN RISK
51 The fourth putative cause of action is formulated by reference to a notice of dispute served on the Principal by Leighton pursuant to clause 47.1 of the General Conditions ('the Notice of Dispute'). That cause of action might be summarised as follows:
(1) The Principal and PKM engaged in the conduct set out in paragraphs 3.3.5 to 3.3.40 of the Notice of Dispute, the effect of which was to convey to Leighton the impression that the design risk being assumed by a successful tenderer was minimal.
(2) The Principal and PKM were aware of a number of matters that were inconsistent with the information provided by them to Leighton, namely, the information referred to in paragraphs 3.3.5 to 3.3.40 of the Notice of Dispute.
(3) Those matters would have conveyed a very different impression of the design risk and were obviously highly material to Leighton's tender, including the matters referred to in paragraphs 3.3.42 to 3.3.57 of the Notice of Dispute.
(4) Neither the Principal nor PKM disclosed those matters to Leighton.
(5) By reason of the foregoing, PKM engaged in conduct that contravened s 52 of the Trade Practices Act.
(6) In the alternative, the Principal engaged in conduct that contravened s 52 of the Trade Practices Act and PKM was involved in that contravention.
52 The Notice of Dispute was dated 11 June 2004 and consisted of some 62 pages, together with a further 38 pages of schedules. Section 1 of the Notice of Dispute consisted of an executive summary, which contained the following 'Overview':
'1.1.1 Leighton's entry into the Contract was induced by misleading and deceptive conduct by [the Principal] and by [the Principal's] agents [PKM]… As a result, Leighton will be entitled to recover all of its losses on the Project from those responsible for [the Principal's] misleading and deceptive conduct pursuant to… [the Trade Practices Act].
1.1.2 Those liable to Leighton for misleading and deceptive conduct and/or aiding, abetting, counselling or procuring misleading and deceptive conduct include [the Principal], PKM…
1.1.3 Leighton would be entitled to recover its anticipated losses of $71,706,278 plus interest pursuant to [the Trade Practices Act].
…'
53 The executive summary in the Notice of Dispute then summarise the alleged misleading conduct as follows:
(1) Leighton's interest in the Contract was drawn by an assurance as to how far advanced the design work was. In the short tender period, Leighton was selectively provided with only information that conveyed the impression that the design documentation was all but complete, fully coordinated and properly validated against the existing building, with very little design work remaining to be done. The impression was conveyed that the state of the existing building, including the condition, locations and dimensions of services and structure, had been taken into account and difficulties resolved. The project was sold as one that involved minimal design risk.
(2) that was false. Leighton was passed a design risk that was vastly different from that represented. The design documentation did not take proper account of the state of the existing building, was not coordinated and its shortcomings have been progressively revealed during demolition and construction.
(3) It will take a Court no time to conclude that the Principal's conduct in providing and withholding was materially misleading. There are many instances where it will be a difficult for a court to escape the conclusion that the Principal must have known that the true state of affairs differed from what it represented.
(4) The true design position, concealed by the Principal, has led to very substantial delay and disruption to Leighton's work. The problems on site, which were unforeseen by Leighton, have required a massive increase in design resources to design around problems, fix the Contract design documents and continue to move the project forward. Architectural resources required have more than doubled that which was planned and structural engineers resources have been required to be increased more than seven-fold. That is a measure of the misrepresentation of how advanced the design was.'
54 Paragraphs 3.3.5 to 3.3.40 of the Notice of Dispute may be summarised as follows:
3.3.5 The Principal issue the request for tender to Leighton on 7 May 2002;
3.3.6 On 9 May 2002, the Principal gave a tender briefing to Leighton and confirmed to Leighton that the project was at an advanced state of design, with only minor detailing to be done. Each of the Principal's principal consultants was presented, who demonstrated by extensive reference to the design documentation that they had carried out a very significant amount of design, development and detailing.
3.3.7 Leighton was informed that there had been detailed consideration of various complex matters and generally that the design process of all consultants, as coordinated by the architect, was so far advanced that it was practically complete, and essentially capable of implementation, with only the remaining detailing outstanding which one would ordinarily expect in the course of construction, including the preparation of shop drawings.
3.3.14 Given that the Project involved extensive remodelling and refurbishing of an existing building, with considerable structural complexity, it was of obvious importance to Leighton that the services and structural consultants had, in preparing their designs, first taken proper steps to ascertain the state of the existing building. If this were not the case, one might anticipate numerous design issues arising during construction, with potential for significant delay, disruption and extra cost.
3.3.17 The architect's schedule required it to coordinate and integrate all design work of the other consultants into the architectural documentation.
3.3.18 That was a normal and expected role for the base building architect on such a project, and it was of importance to Leighton that the architect's scope included such a role. It was important that all services, structural details and architectural elements, both new and existing, had been coordinated so that clashes had been identified and eliminated and such matters as layouts, set downs, ceiling heights etc were checked to ensure that they would work.
3.3.19 The architects scope contained no material exclusion of services, other than the tenancy fitout.
3.3.20 Accordingly, it was reasonable to conclude in the absence of contrary advice that the architect's services extended to the design, including coordination, of the entire building except those interiors where the services extended to coordination only.
3.3.21 Part of the background information provided with the request for tender was a summary outline of scope of services for tender allowance, which scheduled the novated consultants and their services for both the base building and the 'Living Well' tenancy. The architect's services were stated to cover the construction documentation for the base building, and the structural engineers services were stated to cover the construction documentation for both the base building and the Living Well tenancy. That confirmed that the design services for the building were comprehensive save as expressly identified.
3.3.22 By a spreadsheet provided to Leighton on 3 June 2002, the Principal conveyed the information that, as at 31 May 2002, the architect had been paid about 80 per cent of its fees for all work up to and including design and documentation, the structural engineer about 82 per cent and all consultants on average about 84 per cent. As design work was continuing during the tender period, that reinforced the impression that had been conveyed that design and documentation would be all but completed by the time of commencement of the Contract.
3.3.26 Leighton expressed to the Principal its concern to ensure that the amounts said to be outstanding to the consultants were adequate to cover any design and documentation that remained to be done.
3.3.27 At this time, Leighton was told that the design and documentation was virtually complete, with only a small amount of work remaining to be carried out.
3.3.31 Leighton's tender letter of 21 June 2002 contained the assumption that the Principal has received completed Consultancy Agreement Schedule 12 Certificates from all consultants for all work up to the Construction Attendance Stage and that the Principal's silence implicitly affirmed that assumption.
3.3.37 In the light of all the information provided, it was reasonable to conclude that, by the time of the Contract, the design documentation of all consultants was virtually complete in accordance with their retainers, including all that was necessary to verify the state of the existing building, and including coordination and integration of all designs by the architect.
3.3.40 Leighton was required, in the short tender period allowed, to determine the level of design risk and what contingency or qualifications to allow for it in its tender. The Principal had gone out of its way to provide only information to Leighton that conveyed the overwhelming impression that the design and documentation would, by contract date, be all but complete, fully coordinated and properly validated against the existing structure and services, so that very little design work would be required after Contract other than normal detailing during construction.
3.3.41 It now appears that the Principal, in particular identified officers of the Principal, were aware of a large number of matters, which were inconsistent with the information referred to above, which would have conveyed a starkly contrasting impression of the design risks, which were obviously highly material to Leighton's tender, and which the Principal did not disclose.
3.3.42 The Consultants had not carried out the requisite review of available existing building documentation and building services documentation. Nor had they carried out the surveys to document the existing structure and services. Nor had they prepared the reports on the extent and accuracy of the available existing building documentation and building services documentation.
3.3.43 The structural engineers have not carried out verification of the existing building as required.
3.3.44 Such survey of the existing building as had been carried out was clearly no substitute for the survey and verification work that was provided for in the consultancy deeds.
3.3.45 The scope of services negotiated by the Principal with the architect was in fact far less comprehensive than the scope indicated in the material provided to Leighton.
3.3.48 The fact that the architect's scope excluded the hotel rooms and was very limited in other design areas resulted in an absence of coordination in these areas.
3.3.49 There had also been extensive negotiations between the Principal and the structural engineer bearing on scope of services, survey and coordination, which were not disclosed to Leighton.
3.3.50 Given that Leighton was being asked to assume design risk, a course of correspondence detailed in paragraph 3.3.49 ought to have been fully disclosed to Leighton. The Principal should have disclosed to Leighton certain identified matter.
3.3.51 It is difficult to understand how the Principal, acting in good faith, could have chosen not to disclose the structural engineer's correspondence, or the substance thereof, to Leighton.
3.3.52 The combined effect of incomplete scopes of services for the consultants, and inaccurate and incomplete survey information, exacerbated by late design changes and given the extremely tight constraints of an existing structure, was that the coordination of the design documentation of the various design consultants was of utmost importance but was not adequately provided for.
3.3.53 The survey and coordination services called up by the consultancy deeds would have substantially eliminated the risk of the very problems that have occurred.
3.3.54 As a result of the limited scopes of services for the architect and the structural engineer, and the consequential lack of appropriate survey information and proper coordination, the design was in fact not nearly as advanced or reliable as represented by the Principal.
3.3.55 The Principal also failed to disclose a number of matters concerning the apparent requirements and conditions of authorities, which were highly material to the risk that Leighton was being asked to assume, including the following:
(a) Sydney Water's requirements;
(b) Sydney City Council's requirements;
(c) the fact that the RIC had not yet been properly consulted.
3.3.56 An illustration of the consultant's failure to investigate the existing buildings and the Principal's failure to disclose what is found with the fire detection and EWIS systems. As detailed in Schedule 3 of the Notice of Dispute, a large number of existing fire detection and EWIS systems and equipment were depicted in the tender drawings as to be reused. On post-contract investigation, many of these systems were found to be grossly non-compliant, non-functioning or non-existent. Yet the Principal had provided information to authorities, in the form of annual compliance certificates, that the services were compliant with BCA and NSW Fire Brigade requirements.
3.3.57 The presence of asbestos provides another illustration of the state of the existing building, which was not properly examined by consultants and not disclosed by the Principal. This is detailed in Schedule 2 of the Notice of Dispute.
55 Leighton seeks discovery of the following in relation to the fourth cause of action:
'…any document recording, constituting or identifying the knowledge or information held by [PKM] in the period 1 April 2002 to 31 August 2002 concerning:
