Mirvac Queensland Pty Ltd v Shamrock Civil Engineering Pty Ltd

In the matter of Mirvac Queensland Pty Ltd v Shamrock Civil Engineering Pty Ltd, the primary issue before the court was whether the plaintiffs had properly pleaded their claims for damages arising from the failure of the construction of a stormwater harvesting system for a public park, which was intended to be an environmentally sustainable design initiative as part of the Waterfront Newstead project. The stormwater harvesting system was intended to be placed in a public park, now known as Waterfront Park, on land owned by the Brisbane City Council. The first defendant was engaged to construct and install the system, while the second defendant was engaged to aid in the design and documentation of the system. The plaintiffs alleged that the installation failed due to differential movement in the soils and lack of support, leading to significant damage and a partial collapse of one of the tanks. The plaintiffs then filled and abandoned the stormwater harvesting system with the approval of the Council.

The court was required to determine whether the plaintiffs had properly pleaded the claims for damages. The first defendant argued that the pleadings should be struck out, as the plaintiffs had not sufficiently demonstrated any loss or damage that would entitle them to compensation. The plaintiffs, on the other hand, argued that they had lost the benefit and use of the stormwater harvesting system, and that the cost of the installation should be considered as the best particulars of the benefit. The court found that the pleadings did not establish what different position the plaintiffs would have been in had the contract been fully performed, nor did they allege that the first defendant's breach made it impossible to ascertain whether or not the plaintiffs would have made a profit from the performance of the contract. The court concluded that it was appropriate to strike out certain paragraphs of the pleadings and grant leave to re-plead.

In light of the submissions made by the plaintiffs' counsel, the court granted leave to re-plead and directed the plaintiffs to deliver a draft third further amended statement of claim by a specified deadline. The plaintiffs were also ordered to pay the first and second defendants' and second third parties' costs of the application. The court's decision was based on the need for the plaintiffs to better particularise their claims and demonstrate the loss or damage they had suffered as a result of the defendants' actions.
