REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

• collect, organise and understand information related to work orders, basic plans, and safety procedures
• communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the reporting of work outcomes and problems
• plan and organise activities, including the preparation and layout of the worksite and the obtaining of equipment and materials to avoid any back tracking, workflow interruptions or wastage
• work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
• use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate other material requirements
• use pre-checking and inspection techniques to anticipate assembly problems, avoid re-working and avoid wastage
• use the limited workplace technology related to the assembly, including tools, equipment, materials and measuring devices

Required knowledge 

• the interpretation of plan representation of base design
• identification of hand and/or power tools, materials, equipment, processes and procedures
• workflow in relation to base production

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 of evidence 

• Interpret work order and locate relevant information
• Apply safe handling requirements for equipment and products and materials, including use of personal protective equipment
• Follow work instructions, operating procedures and inspection practices to:

• minimise the risk of injury to self and others
• prevent damage to goods, equipment and products
• maintain required production output and product quality

• Assemble base components to construct at least one sprung base unit
• Work effectively with others
• Modify activities to cater for variations in workplace context and environment

Resource implications 

Access to plans, hand and/or power tools, equipment, materials, jigs, appropriate machinery, and a suitable work area.

Method of assessment 

Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts.

Assessment should be by direct observation of tasks and questioning on underpinning knowledge.

Assessment should be conducted over time and will generally be in conjunction with assessment of other units of competency.

Context of assessment 

Assessment may occur on the job or in a workplace simulated facility with relevant process equipment, materials, work instructions and deadlines.

RANGE STATEMENT 

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
