CPPBDN5009
Produce compliant client-approved designs for small-scale building design projects


Application

This unit of competency specifies the outcomes required to prepare, consult on and refine designs for building design projects covered by the Building Code of Australia (BCA), except construction Type A buildings, to produce client-approved drawings that comply with planning approval requirements. It involves the application of creative design skills, knowledge of human lifestyles and cycles, and knowledge of safe and sustainable construction materials and methods. It includes consultation and collaboration with technical experts, such as structural engineers.

The unit supports the work of building designers who produce design drawings that meet client and compliance requirements for small-scale building design projects, including alterations and additions, heritage restorations, and new buildings, including houses, factories, motels, offices, restaurants, retail and service outlets, and warehouses.

Licensing, legislative, regulatory or certification requirements apply to this unit of competency in some States. Relevant state and territory regulatory authorities should be consulted to confirm those requirements.
