Elements and Performance Criteria

1. Use drawing instruments, equipment and materials to set out drawings.
   • Drawing instruments, equipment and materials are used to produce working drawings for residential buildings with scaled line work, simple geometric shapes, lettering, numbering and correct setting out of drawings.
2. Produce drawings at varying scales using architectural conventions for linework, lettering and symbols.
   • Linework is applied in a range of different types and media in accordance with standard industry drawing practice for production of building drawings.
   • Hand letter text is formed in a variety of formats.
   • Different drawing scales are identified and used.
   • Graphic symbols are identified and used.
   • Orthographic projection in building drafting applications is drawn accurately to scale.
   • Notations and dimensions are added to complete drawing.
3. Read and interpret plans and specifications for a single storey dwelling.
   • Interrelationships between plans and specifications are identified and interpreted.
   • Key information is located and interpreted according to drawings, specifications and application of Australian standards.
4. Draw three dimensional sketches.
   • Annotated 3-D sketches of various building components are produced to specifications using parametric (e.g. isometric) or perspective techniques.
5. Produce building permit approval drawings.
   • Building permit approval drawings, including detailed specification notes for residential dwellings, are completed to architectural conventions.

Required Skills

Required skills

Required skills for this unit are ability to respond to change and contribute to workplace responsibilities such as current work site environmental and sustainability frameworks or management systems communication skills to enable clear and direct communication using questioning to identify and confirm requirements share information listen and understand written skills to produce detailed specification notes provide notations and dimensions on drawings use language and concepts appropriate to cultural differences use and interpret nonverbal communication interpret and apply information from plans and specifications to develop required drawings numeracy skills to produce drawings for residential buildings planning and organisational skills to collect organise and analyse information technological skills to enable production of working drawings complete documentation and calculations

Required knowledge

Required knowledge for this unit is codes of conduct and ethics drafting and drawing protocols processes for the administration and preparation of documentation processes for the interpretation of reports working drawings and specifications relevant federal state or territory legislation and local government policy and procedures research methods structural design and construction principles of buildings terminology definitions and fault identification

Evidence Required

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
Overview of assessment	This unit of competency could be assessed in the workplace or a close simulation of the workplace environment provided that simulated or projectbased assessment techniques fully replicate construction workplace conditions materials activities responsibilities and procedures
Critical aspects for assessment and evidence required to demonstrate competency in this unit	A person who demonstrates competency in this unit must be able to provide evidence of the ability to comply with OHS regulations applicable to workplace operations apply organisational management policies and procedures including quality assurance requirements where applicable produce two and threedimensional drawings for residential building projects including at least one orthographic one isometric and one perspective drawing produce drawings to appropriate bodyindividual as determined by the project brief
Context of and specific resources for assessment	This competency is to be assessed using standard and authorised work practices safety requirements and environmental constraints Assessment of essential underpinning knowledge will usually be conducted in an offsite context Assessment is to comply with relevant regulatory or Australian standards requirements Resource implications for assessment include an induction procedure and requirement realistic tasks or simulated tasks covering the mandatory task requirements relevant specifications and work instructions tools and equipment appropriate to applying safe work practices support materials appropriate to activity workplace instructions relating to safe work practices and addressing hazards and emergencies material safety data sheets research resources including industry related systems information Reasonable adjustments for people with disabilities must be made to assessment processes where required This could include access to modified equipment and other physical resources and the provision of appropriate assessment support
Method of assessment	Assessment methods must satisfy the endorsed Assessment Guidelines of the Construction Plumbing and Services Training Package include direct observation of tasks in real or simulated work conditions with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application reinforce the integration of employability skills with workplace tasks and job roles confirm that competency is verified and able to be transferred to other circumstances and environments Validity and sufficiency of evidence requires that competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice with a decision on competency only taken at the point when the assessor has complete confidence in the persons demonstrated ability and applied knowledge all assessment that is part of a structured learning experience must include a combination of direct indirect and supplementary evidence Assessment processes and techniques should as far as is practical take into account the language literacy and numeracy capacity of the candidate in relation to the competency being assessed Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties such as existing supervisors team leaders or specialist training staff
