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 produce building design drawings and documentation with appropriate scale and notations using current industry-standard software packages with building information modelling (BIM) capability.

The unit supports drafters who assist and work under the supervision and instruction of architects and building designers and produce design documentation for all types of residential, commercial and industrial buildings as defined in the Building Code of Australia (BCA), up to the stage of client approval of the design concept. It also covers ensuring that the drawings and documentation meet compliance requirements for the type of building and location and are formatted and notated to facilitate understanding by the client.

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.
