Description
This unit of competency covers the skills required by an Engineering Tradesperson - Fabrication for marking out general fabrications using geometric development techniques. The marking out is done to specifications interpreted from technical drawings and job specifications.
Notes
Elements and Performance Criteria
1. Transfer dimensions from a detail drawing to work
- 1.1. Specifications and work requirements are determined and understood using correct and appropriate calculations
- 1.2. Development is carried out to specifications or standard operating procedures using appropriate tools and equipment
- 1.3. Datum points are correctly established and marked appropriate to task requirements
2. Make templates as required
- 2.1. Appropriate template material is chosen
- 2.2. Templates are produced to specification
- 2.3. Correct storage procedures are followed including labelling and identification to standard operating procedures
3. Develop patterns as required
- 3.1. Parallel line, radial line and triangulation development methods are chosen and applied
- 3.2. Allowances for fabrication and assembly are correctly determined and transferred
4. Interpret relevant codes, standards and symbols
- 4.1. Relevant standards/codes and symbols are interpreted
- 4.2. Requirements of standards/codes are interpreted and applied to materials and processes
5. Estimate quantities of materials from detail drawings
- 5.1. Materials are correctly identified
- 5.2. Quantities are estimated from drawings
- 5.3. Material wastage is minimised
RANGE STATEMENT

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 mark out general fabrications using geometric development. 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 apply the skills covered in this unit of competency in new and different workplace situations and contexts. Critical aspects of assessment and evidence include:
examining detailed drawings for fabrication requirements and specifications including materials, measurements and tolerances, joining methods, standards and code requirements
correctly calculating allowances for fabrication and assembly including shrinkage, thickness and inside/outside measurements
correctly establishing and marking datum points
selecting and using parallel line, radial line and triangulation development methods with minimum material wastage with accurate dimensions and allowances
accurately producing templates.
Context of and specific resources for assessment
This unit has been developed to support training in and recognition of trade level competency in marking out using geometric development as applied to a sheet metal or metal fabrication environment. Assessment should emphasise a workplace context and procedures found in the candidate's workplace.
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.
Method of assessment
Typically, persons engaged in Engineering Tradesperson - Fabrication work are required to apply their geometric development skills and techniques across a range of jobs and specifications.
A single assessment event is not appropriate. On the job assessment should be included as part of the assessment process wherever possible. Where assessment occurs off the job, judgement must consider evidence of the candidate's performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit.
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
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with applying geometric development or other units requiring the exercise of the skills and knowledge covered by 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.
