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 with site supervisor, other workers 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 material requirements
• use pre-checking and inspection techniques to anticipate fabrication problems, avoid re-working and wastage
• use the limited workplace technology related to this fabrication, including tools, equipment, materials and measuring devices

Required knowledge 

• the interpretation of production plans and drawings
• workflow in relation to mattress and base fabrication
• identification of hand and/or power tools, materials, equipment, processes and procedures

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 instructions and locate and apply relevant information
• Apply safe handling requirements for equipment, 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
• achieve required product quality

• Fabricate and finish at least one basic mattress and base product which requires the use of:

• quilted fabric
• mattress-making hand tools and equipment
• springs or a spring unit
• sewing machines

• Work effectively with others

Resource implications 

Access to plans, tools, equipment, materials, a work area and a specified project.

Method of assessment 

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

Assessment may be conducted 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 equipment, materials, work instructions and deadlines.
