This unit of competency specifies the outcomes required to produce construction detail drawings and specifications for all types of residential, commercial and industrial buildings as defined by the Building Code of Australia (BCA). Construction detail drawings will provide construction contractors with information required to select, cost and apply construction materials and methods according to the client’s design brief and relevant development approvals. It also covers the production of drawings where variations are required during the construction process. The unit supports drafters who assist and work under the instruction and supervision of an architect or building designer to produce drawings relied upon throughout the various construction phases of a building development.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.
