CPPBDN4009
Analyse building design drawings and review findings


Application

This unit of competency specifies the outcomes required to analyse drawings relating to building designs for residential, commercial and industrial buildings, as defined by the Building Code of Australia (BCA).

It covers interpreting construction industry conventions for drawings, and analysing drawings for different projects to identify design and technical features. It also covers presenting findings and discussing these with the architect or building designer to inform the design process.

The unit supports the work of drafters who assist and work under the supervision and instruction of architects, building designers and other personnel, such as home sustainability assessors.

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.

Unknown elements of, or anomalies in, architectural drawings are noted for discussion with architect or building designer.

3.

Analyse drawings from other construction disciplines.

3.1.

Land survey drawings are analysed to identify topographical features of site for building design projects and requirements for cutting and filling.

3.2.

Structural engineering drawings are analysed to determine construction methods and load considerations for building design project.

3.3.

Drawings and reports from electrical, hydraulic, fire and mechanical engineers are analysed to determine layout of services for building design project.

3.4.

Drawings and drawing notations from consultants are analysed to identify recommendations for building design project.

3.5.

Unknown elements of, or anomalies in, drawings from other disciplines are noted for discussion with architect or building designer.

4.

Present and discuss findings.

4.1.

Advice is sought where required from architect or building designer to assist in identifying and analysing unknown elements of drawings.

4.2.

Findings from analysis of architectural drawings are presented to, and discussed with, architect or building designer to inform building design process.

4.3.

Findings from analysis of drawings from other construction disciplines are presented to, and discussed with, architect or building designer to inform building design process.

4.4.

Strategies for producing corrections to drawings are developed in consultation with architect or building designer and followed up as required.

Foundation Skills

This section describes core skills that are essential to performance and not explicit in the performance criteria. Employment skills essential to performance are explicit in the performance criteria of this unit of competency.

Skill

Performance feature

Learning skills to:

access Australian standards to assist in developing understanding of different types of drawings and drawing standards and conventions

draw on experience in drawing analysis and apply to new work.

Numeracy skills to:

interpret and check the accuracy of numerical information in technical drawings and reports, including dimensions, ratios, scales and scale conversions

use mathematical language to discuss with colleagues findings from analysis of drawings, such as anomalies in dimensions or inaccuracies in scale conversions.

Oral communication skills to:

participate in discussions in the workplace and with external specialists using specialised vocabulary relating to building designs, including the names used for different types of drawings and the names for different building elements and fixtures.

Reading skills to:

understand specialised vocabulary, abbreviations and acronyms specific to building design work, including terms used by external consultants

use different reading strategies to locate specific and sometimes complex details in drawings and reports.

Writing skills to:

make concise and technically accurate personal notes on findings from analysis of drawings and reports and discussions with designer.
