Unit of competency details

Unit descriptor 

This unit covers producing fabrication/structural assembly, fabrication/structural layout drawings to AS 1100 or equivalent.

Application of the unit 

Skills covered by this unit are applied individually or in a team environment where comprehensive responsibility for the production of the drawing is exercised, and critical dimensions and associated tolerances are determined where required.

Manual drafting and drawing equipment is used or where a CAD system is used, Unit MEM09009C (Create 2D drawing using computer aided design system) and/or Unit MEM09010C (Create 3D models using computer aided design system) should also be considered.

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

ELEMENT 

PERFORMANCE CRITERIA 

1. Prepare fabrication/structural assembly, layout drawing

1.1. All drawings are produced to Australian Standard 1100 or equivalent.

1.2. Dimensions of various components are determined and inserted and appropriate symbols for limits and fits, surface texture and geometric tolerances are included.

REQUIRED SKILLS AND KNOWLEDGE 

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

Required skills 

Look for evidence that confirms skills in:

• producing all drawings in accordance with AS1100 or equivalent
• representing the function of each component within the assembly/layout in accordance with design specifications/operational requirements
• manufacturing, fabricating and assembling all components in accordance with the specifications contained in the drawings
• where appropriate, correctly orientating all components to surrounding structures and services
• where appropriate, modifying drawings to ensure conformance to specification AS1100 or equivalent, and/or changes to production, assembly and fabrication requirements and/or the availability of standard hardware items etc.
• reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents
• planning and sequencing operations
• checking and clarifying task related information
• checking for conformance to specifications
• undertaking numerical operations, geometry and calculations/formulae within the scope of this unit

Required knowledge 

Look for evidence that confirms knowledge of:

• function of each component within the assembly/layout
• manufacturing, fabrication and assembly procedures to be used in producing the components/assemblies
• reason for ensuring that all components are correctly orientated to existing or proposed structures and services
• reasons for updating/modifying drawings to incorporate changes to specifications, production, assembly and fabrication methods and availability of standard hardware items, etc.
• hazards and control measures associated with performing advanced structural detail drafting, including housekeeping
• safe work practices 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.

Overview of assessment 

A person who demonstrates competency in this unit must be able to perform advanced structural detail drafting. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment 

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with performing advanced structural detail drafting or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment 

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment
