Construction timbers in Queensland

'Construction timbers in Queensland' (CTIQ) describes how to use different timbers in Queensland. The publication (in two parts) is noted as a primary referenced document in the Queensland variations to the Building Code of Australia (BCA).

CTIQ describes the properties of timbers used in the construction of Class 1 to Class 10 buildings (e.g. houses, carports, garages, greenhouses and sheds) in Queensland, as well as other purposes such as furniture, landscaping and outdoor structures (e.g. playgrounds, fences). It also recommends appropriate uses of timbers across the state.
