The Building Code of Australia (BCA) includes a specific requirement for the use of suitable materials in construction. In addition, the Australian Building Codes Board have published a guide for technical committees, manufacturers and others on the durability and life-expectancy requirements for building materials, assemblies and sub-assemblies for use in accordance with the BCA (Australian Building Codes Board, 2002). Construction timbers in Queensland provides information on the properties and performance of timber that will satisfy these requirements. Further, structural timber scheduled for the appropriate conditions of use in this publication will meet the ‘construction deemed to satisfy’ provisions of the BCA.
