Unit context
Competency requires the demonstration of two and three dimensional drawing skills and compliance within the context of relevant legislations, the Building Code of Australia and Australian Standards.

The Evidence Guide identifies the critical aspects, knowledge and skills to be demonstrated to confirm competency for this unit. This is an integral part of the assessment of competency and should be read in conjunction with the Performance Criteria and Range Statement.

What critical aspects of evidence are required to demonstrate competency in this unit?
Compliance with occupational health and safety regulations applicable to workplace operations.
Application of organisational management policies and procedures including quality assurance requirements where applicable.
Production of two and three dimensional drawings for residential building projects, including at least one orthographic, one isometric and one perspective drawing.
Provision of drawings to appropriate body/individual as determined by the project brief.
Application of strategic plans, workplace policies and procedures.

Are there any other units which should be assessed with this unit or which relate directly to this unit?
There are no specified relationships.
Holistic assessment should be applied where appropriate to form a complete work function.

What specific knowledge is required to achieve the performance criteria?
Processes for the interpretation of reports, working drawings and specifications.
Drafting and drawing protocols.
Relevant national, State/Territory legislation and local government policy and procedures.
Structural, design and construction principles of buildings.
Terminology, definitions and fault identification.
Codes of conduct and ethics.
Research methods.
Processes for the administration and preparation of documentation.

What specific underpinning skills are required to achieve the performance criteria?
These include a number of processes that are learned throughout work and life, which are required in most jobs. Some of these are covered by the national key competencies, although others may be added. The questions below highlight how these processes are applied in this competency unit. The number in brackets indicates the level to which the key competency needs to be demonstrated where (1) working within set conditions and processes, (2) management or facilitation of conditions or processes are exercised, and (3) design and/or development of conditions or process are required.

How will the candidate apply the following key competency in this unit?
The candidate will need to:
Collect, analyse and organise information
Research, analyse, organise and understand the application and production of working drawings for residential buildings. Level 3
Communicate ideas and information
Communicate and negotiate ideas and information to translate legislation enabling production of working drawings for residential buildings. Level 3
Plan and organise activities
Plan and organise activities including the planning of working drawings for residential buildings and analytical processes related to organisation of regulatory factors. Level 3
Work with others and in a team
Work with others and in a team by recognising dependencies and using co-operative approaches to optimise satisfaction and productivity. Level 2
Solve problems
Establish analytical processes, including diagnostic processes, which anticipate and allow for risks, cater for both direct and indirect evidence, avoid or minimise reworking and avoid wastage. Level 3
Use mathematical ideas and techniques
Use mathematical ideas and techniques to correctly complete measurements, calculate analytical requirements, scales and numbering systems, quantify, survey and present analytical results. Level 2
Use technology
Use workplace technology related to information gathering and analysis, diagnosis, information research, report writing, production of working drawings, administration and management procedures. Level 2

In what context should assessment occur?
Competency is demonstrated by performance of all stated criteria, including paying particular attention to the critical aspects and the knowledge and skills elaborated in the Evidence Guide and within the scope defined by the Range Statement.
Assessment must take account of the endorsed assessment guidelines in the Construction Training Package.

What methods of assessment should apply?
Assessment of this competency is most likely to be project related under real or simulated conditions and require portfolios or other forms of indirect evidence of process. Direct evidence may include certification of compliance on the final outcome or authorisation for commencement by a competent authority.
Assessment must confirm the inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment should reinforce the integration of the key competencies.

What are the specific resource requirements for this unit?
A situation, real or realistically simulated, requiring working drawings for residential buildings.
The learner and trainer should have access to appropriate documentation and resources normally used in the workplace.
