Unit of competency details

Unit descriptor 

This unit covers the skills and knowledge to construct stock size blocks according to size and fit specifications.

Application of the Unit 

The unit applies to the construction of blocks for use in garment production to meet size and fit specifications. Blocks are used as the basis for pattern making to develop new styles.

Work conducted requires some discretion and judgment.

Work may be conducted in small to large scale enterprises and may involve individual and team-related activities.

The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include:

• requirements prescribed by legislation, awards agreements and conditions of employment
• standard operating procedures
• work instructions
• oral, written and visual communication
• quality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section output
• housekeeping
• tasks related to environmental protection, waste disposal, pollution control, and recycling

This unit requires skills associated with communication to interpret documentation relating to quality standards, specifications, measurement and sizing. Planning and organisation and problem solving skills are required to construct stock size blocks according to size and fit specifications. Self management skills are used to confirm work meets quality requirements.

Prerequisites 

Employability Skills 

This unit contains employability skills.

ELEMENT 

PERFORMANCE CRITERIA 

1 Interpret size and fit

1.1 Size and fit specifications and Australian Standards are interpreted and clarified with designer or relevant personnel.

1.2 Base size to be constructed is identified.

1.3 Base size and fit model are checked for compatibility.

1.4 Size is evaluated and recorded in relation to specification of fit model, body movement and comfort.

2 Construct block

2.1 Appropriate drafting principles and methods are selected for block construction.

2.2 Measurements of fit model  are analysed and input into block drafting formulas and methodology.

2.3 Ease allowance  is determined.

2.4 Block is constructed using patternmaking technical skills  and OHS practices  and checked to ensure compliance with requirements.

2.5 Methods and formulas  used are documented.

3 Construct and assess toiles

3.1 Toiles are accurately cut and constructed from block.

3.2 Correct proportion, fit and balance is confirmed by fitting and necessary minor adjustments are made.

3.3 Accuracy of toiles is evaluated in relation to fit, comfort and appropriate to base size specifications.

4 Develop and complete final block

4.1 Information from toiles, including any minor adjustments is transferred to blocks.

4.2 Final blocks are completed, labelled and checked for accuracy and completeness of all necessary information, and to ensure compliance with specifications.

5 Maintain records

5.1 Blocks are filed  and stored.

5.2 All required documentation is completed.

• identifying improvements
• using workplace practices
• using OHS practices
• recording and reporting accidents and incidents
• assessing operational readiness of equipment used and work processes
• recognising and adapting to cultural differences in the workplace, including modes of behaviour and interactions
• completing work systematically with attention to detail without damage to goods and equipment

Resource implications 

Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Context for assessment 

Assessment may occur on the job or in an appropriately simulated environment.

Interdependent assessment 

This unit may be assessed independently or in combination with other relevant units.

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. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.

Legislative/regulatory requirements

All work must comply with relevant Federal and State or Territory legislative or regulatory requirements.

Measurement of fit model must include:
