Application
This unit of competency specifies the outcomes required to produce digital 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.
The unit supports preparing and presenting 3-D models to clients and stakeholders to illustrate concepts of small-scale building design projects, including alterations and additions, heritage restorations, and new buildings, including houses, factories, motels, offices, restaurants, retail and service outlets, and warehouses. It applies to building designers working on small-scale 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.
Elements and Performance Criteria

3. | Produce digital 3-D model presentation. | 3.1. | 3-D models are manipulated to create a range of views according to project and workplace requirements. |
3.2. | Dimensions and notations are applied to views as required. | ||
3.3. | 3-D models are checked for accuracy, completeness and quality according to workplace procedures. | ||
3.4. | Presentation styles and display controls are selected and applied according to project and workplace requirements. | ||
4. | Present digital 3-D models to clients. | 4.1. | 3-D models are presented and explained to client to ensure client understanding of designs, according to workplace procedures. |
4.2. | Client feedback is encouraged and incorporated into models. | ||
4.3. | Files for finalised 3-D models are saved and processed according to project and workplace requirements. | ||
Evidence of Performance

building designers’ duty of care to ensure quality and safety of designs
contextual and site constraints to be reflected in model
conventional and sustainable construction materials and methods, including their application, behaviour, characteristics, performance and interactions with other materials
design drawing and representation methods
digital file management procedures
functions and operation of 3-D modelling software programs
hazards of site, materials, construction practices and building use over its life cycle
key features of building life cycles
legislation, codes and standards that apply to sustainable design requirements for small-scale building design projects specified in the performance evidence
organisational scope of business, service levels and fees relating to model production process.
