CPPBDN5015
Produce compliant client-approved working drawings for non-residential buildings


Application

This unit of competency specifies the outcomes required to produce detailed working drawings of designs for commercial and industrial buildings covered by the Building Code of Australia (BCA), except construction Type A buildings. The drawings are required for submission to the regulatory authority for building approval and for use by construction personnel in the building process. The unit involves liaising with the client and regulatory authorities to finalise the building approval process.

The unit supports building design projects that fall within the definitions of construction types B and C in the BCA, including factories, motels, offices, restaurants, retail and service outlets, and warehouses. It applies to building designers who prepare sets of working drawings for non-residential building design projects.

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.

Evidence of Performance

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit.

The person must also prepare and organise complete and compliant sets of working drawings for three projects (except construction Type A buildings), each of a maximum area of 2000 square metres and involving different classes of commercial buildings as defined in the Building Code of Australia (BCA) section of the National Construction Code (NCC), consisting of:

one project incorporating Classes 2, 5, 6 and 7a

implications of changes to designs, including compliance issues, costs and client satisfaction with outcomes

legislation, codes and standards, including drawing standards, that apply to small-scale building design projects specified in the performance evidence

organisational scope of business, service levels and fees relating to drawing process.


Assessment Conditions

The following must be present and available to learners during assessment activities:
