Placer (Granny Smith) Pty Ltd v Thiess Contractors

Placer (Granny Smith) Pty Ltd (the plaintiff) brought proceedings against Thiess Contractors (the defendant) in the Supreme Court of New South Wales. The dispute concerned the interpretation of a contract for the construction of a tailings dam at the Granny Smith gold mine in Western Australia. The plaintiff alleged that the defendant had breached the contract by failing to construct the dam in accordance with the agreed specifications, leading to a failure of the dam and significant losses for the plaintiff.

The central legal issue before the court was whether the defendant had breached its contractual obligations regarding the design and construction of the tailings dam. Specifically, the court had to determine whether the defendant had complied with the express terms of the contract, including those relating to the provision of adequate design and construction services, and whether any implied terms had been breached. The court also considered the extent of the defendant's liability for the resulting damage.

The court's reasoning focused on a detailed analysis of the contract's provisions, particularly those relating to the defendant's responsibilities for design and construction. The judges examined the evidence presented by both parties regarding the dam's construction and the causes of its failure. The court applied principles of contract law, including the duty to perform contractual obligations with reasonable care and skill, and the rules governing the assessment of damages for breach of contract. The court found that the defendant had breached its contractual obligations.

The court ordered that the defendant pay damages to the plaintiff in an amount to be assessed.
