Modification History

New unit

Unit Descriptor

This unit of competency specifies the outcomes required to produce three-dimensional (3-D) models for building design projects covered by the Building Code of Australia (BCA), except construction Type A buildings.

It also covers demonstrating and discussing the representations with clients and stakeholders.

Application of the Unit

This unit of competency supports building designers who prepare and present 3-D models to clients and stakeholders to illustrate concepts of small-scale building design projects.

Licensing/Regulatory Information

Work in this area must be completed according to relevant legislative, industry and organisational requirements, including occupational health and safety (OHS) policies and procedures.

Different states and territories may have regulatory mechanisms that apply to this unit. Users are advised to check for regulatory limitations.


Not applicable.

Employability Skills Information

This unit contains employability skills.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria


Set up and manage digital files


Files for digital 3-D models of small-scale building design projects  are created, named, saved and retrieved according to project and workplace requirements.


Digital two-dimensional (2-D) drawing files are imported as required using appropriate file transfer protocols.


Files are exported and transferred for client and consultant use in required formats using appropriate file transfer protocols.


Create digital 3-D models of building designs


Sources of customised architectural objects  for digital 3-D models are identified and accessed.


3-D modelling functions of design software are operated to create 3-D model and additional objects according to project and workplace requirements.


Architectural objects are applied to 3-D models according to project and workplace requirements.


Produce 3-D model presentation


3-D models are manipulated to create a range of views  according to project and workplace requirements.


Dimensions and notations  are applied to views as required.


3-D models are checked for accuracy, completeness and quality according to workplace procedures.


Presentation styles and display controls  are selected and applied according to project and workplace requirements.


Present digital 3-D models to clients


3-D models are presented and explained to client to ensure client understanding of designs, according to workplace procedures.


Client feedback is encouraged and incorporated into models.


Files for finalised 3-D models are saved and processed according to project and workplace requirements.

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

A person should demonstrate the ability to:

  • produce digital 3-D models of a range of building designs that meet client expectations and workplace requirements
  • present digital 3-D models of a range of building designs to clients, including:
  • explaining design using terms appropriate to clients’ understanding
  • encouraging and answering questions and feedback.

Context of and specific resources for assessment

Assessment of this unit:

  • must be in the context of the work environment
  • may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills
  • must meet relevant compliance requirements.

Resource implications for assessment include:

  • access to:
  • suitable assessment venue and equipment
  • suitable simulated or real opportunities and resources to demonstrate competence
  • assessment instruments.

Method of assessment

Assessment for this unit must verify the practical application of the required skills and knowledge, using one or more of the following methods:

  • written and/or oral assessment of the candidates required knowledge for the unit
  • observed, documented and/or firsthand testimonial evidence of the candidates
  • implementation of appropriate procedures and techniques for the safe, effective and efficient achievement of the required outcomes
  • identification of the relevant information and scope of the work required to meet the required outcomes
  • identification of viable options and the selection of options that best meet the required outcomes
  • consistently achieving the required outcomes.

Guidance information for assessment

This unit could be assessed on its own or in combination with other units relevant to the job function.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and/or assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.
