Release 1 |
This version first released with CPP Property Services Training Package Release 11.0. New unit. |
Application
This unit specifies the skills and knowledge required to design timber-framed buildings in accordance with AS 1684 Residential Timber Framed Construction (AS 1684), AS 4055 Wind loads for housing (AS 4055) and within the context of the National Construction Code (NCC). It includes designing timber-framed structures for one and two-storey buildings and selecting, sizing and positioning structural elements.
This unit is suitable for drafters and building designers who apply integrated technical and theoretical skills to determine framing requirements and apply compliant materials and processes to timber framing as part of a building design project.
This unit forms part of the licensing requirements for people engaged in building design in some states and territories. For further information, check with the relevant regulatory authority.
