Performance Evidence

Interpret work orders and locate and apply relevant information

Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment

Identify materials used in the work process

Follow work instructions, operating procedures and inspection processes to:

minimise the risk of injury to self or others

prevent damage to goods, equipment and products

maintain required production output and product quality

Design and produce at least two (2) 2-D CAD drawings and two (2) 3-D CAD drawings that document the requirements of the design brief applying drafting and drawing protocols in accordance with Australian Standards and the Building Code of Australia (BCA)

Apply design elements and principles to designing with CAD applications

Use mathematical ideas and techniques to correctly complete measurements, calculate area/volume and estimate material requirements

Communicate ideas and information to enable confirmation of work requirements and specifications, presentation of design/colour concepts, the reporting of work outcomes and problems

Apply design concepts to drawings

Initiate new ideas and work techniques

Avoid backtracking, work flow interruptions or wastage

Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
