CPPBDN5007
Inspect and analyse sites and produce measured drawings for small-scale building design projects


Application

This unit of competency specifies the outcomes required to inspect sites for commercial, industrial and residential building design projects covered by the Building Code of Australia (BCA), except construction Type A buildings. Site inspections are conducted to determine contours and measurements; existing conditions, structures, features and services; and neighbourhood characteristics. The unit involves analysing sites; determining orientation and layout of building, access and egress points, and existing utilities and services infrastructure; and producing measured drawings for projects.

The unit supports inspecting and analysing sites, including alteration and additions, heritage restorations, and new buildings, including houses, factories, motels, offices, restaurants, retail and service outlets, and warehouses. It applies to building designers who gather and correlate field data from small-scale building design project sites and produce accurate measured site drawings.

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 produce measured drawings for three different project sites, as listed below, where each site has significantly different features and characteristics:

key features of building life cycles to accurately assess potential for re-use of existing buildings

project site WHS requirements

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

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

principles of building design, including sustainable design

safe operating procedures for using levelling and surveying equipment, including:

chains and tapes

global positioning systems (GPS)

automatic, dumpy and tilting levels

theodolites.
