ELEMENT

Elements describe the essential outcomes of a unit of competency. Elements describe actions or outcomes that are demonstrable and assessable.

PERFORMANCE CRITERIA

Performance criteria describe the required performance needed  to demonstrate achievement of the element – they identify the standard for the element. Where bold / italicized text is used, further information or explanation is detailed in the required skills and knowledge and/or the range statement.

Assessment of performance is to be consistent with the evidence guide.

1. Identify steel structure to be designed
  • Occupational Health and Safety/Workplace Health and Safety (OHS/WHS) requirements and environmental requirements for a given work area are determined.
  • Established OHS/WHS requirements and risk control measures and procedures are followed in preparation of the work
  • Safety hazards which have not previously been identified are documented and risk control measures devised and implemented in consultation with appropriate personnel.
  • Design requirements for the steel structure are identified from the design

EVIDENCE GUIDE

The evidence guide provides advice on assessment and must be read in conjunction with the Elements, Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment section in Section B of the Accreditation Submission.

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 associated performance criteria, including required skills and knowledge. Specifically they must be able to:
    • implement OHS/WHS procedures and practices including the use of risk control measures as specified in the performance criteria and range
    • demonstrate the ability to design a steel structure in accordance to job specifications and relevant Australian standards on more than one occasion and in different 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
  • Resources required for assessment include:
    • OHS/WHS policy and work procedures and instructions.
    • Access to workplace or work real environment and a variety of conditions
    • Operational access to relevant design equipment, tools, materials and consumables
    • Access to relevant Australian Standards, plans, drawings and instructions and manufacturer’s specifications/manuals.

 

 

 

Methods of assessment
  • For valid and reliable assessment of this unit, evidence should be gathered through a range of methods to indicate consistent performance.
  • Evidence must involve demonstration of practical skills and may also include:
    • observation of processes and procedures
    • oral and/or written questioning on required knowledge and skills
    • testimony from supervisors, colleagues, clients and/or other appropriate persons
    • inspection of the final design solutions or outcomes
    • portfolio of documented
  • Where performance is not directly observed any evidence should be authenticated by colleagues, supervisors, clients or other appropriate
  • Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.
