Unit Of competency

Modification History

Release 1. New unit.

This version first released with CPP Property Services Training Package Version 1.

Application

This unit of competency specifies the outcomes required to analyse drawings relating to building designs for residential, commercial and industrial buildings, as defined by the Building Code of Australia (BCA).

It covers interpreting construction industry conventions for drawings, and analysing drawings for different projects to identify design and technical features. It also covers presenting findings and discussing these with the architect or building designer to inform the design process.

The unit supports the work of drafters who assist and work under the supervision and instruction of architects, building designers and other personnel, such as home sustainability assessors.

Licensing, legislative, regulatory or certification requirements apply to building design drafting in some states. Relevant state and territory regulatory authorities should be consulted to confirm those requirements.
