Bluechip Development Corporation (Gladstone) Pty Ltd v Sunstruct Pty Ltd

Bluechip Development Corporation (Gladstone) Pty Ltd (Bluechip) and Sunstruct Pty Ltd (Sunstruct) were parties to a building contract for the construction of a shopping centre. A dispute arose between them concerning the interpretation of a clause in the contract relating to the payment of a progress claim. The matter came before the Supreme Court of Queensland.

The primary legal issue before the Court was whether Sunstruct was entitled to payment of its progress claim, notwithstanding that Bluechip alleged the work was not substantially completed. This turned on the proper construction of clause 34.1 of the building contract, which stipulated that a progress claim would be payable unless the principal (Bluechip) issued a payment notice stating that the amount claimed was not payable.

The Court considered the plain meaning of clause 34.1, noting that it created a positive obligation on Bluechip to issue a payment notice if it intended to withhold payment. The absence of such a notice meant that the progress claim was payable, irrespective of whether the work was substantially completed. The Court rejected Bluechip's argument that substantial completion was a prerequisite to payment under the contract, finding that the contract did not expressly or implicitly impose such a condition. The Court applied the principle that contractual terms should be given their ordinary and natural meaning, and that clear and unambiguous language would be given effect.

The Court ordered that Bluechip pay Sunstruct the amount claimed in the progress claim, together with interest and costs.
