Elements and Performance Criteria

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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Parameters to the selection requirements
Parameters to the selection requirements include:
determination of the degree of innovation and creativity expected by the client
selection process limits and budgets
product cost limits and budgets
performance and efficiency specifications
equipment availability, capacities and restrictions
specified administrative, communication and approval procedures
other special features and limits in the requirements
OHS, regulatory requirements, codes of practice and enterprise procedures
OHS, regulatory requirements, codes of practice and enterprise procedures may include:
OHS Acts and regulations
relevant standards
codes of practice from Australian and overseas engineering and technical associations and societies
risk assessments
registration requirements
safe work practices
state and territory regulatory requirements
Initial qualitative and quantitative analysis
Initial qualitative and quantitative analysis may include:
a hazard and risk analysis related to existing or proposed plant or equipment
routine noise and vibration monitoring data or investigative measurements
Appropriate software and validation techniques
Software may be employed for performance analysis/modelling. Underpinning program techniques and algorithms should be understood, such as:
the use of FEA and numerical methods within object oriented modelling techniques
Validation techniques include:
comparison of traditional solutions for simple thermodynamic system performance problems with software solutions to the same problems
review of previously implemented system performance challenges which were completed using the software
Standards and codes
Standards and codes refer to all relevant Australian and international standards and codes applicable to a particular thermodynamic system task
Sustainability
Sustainability is used to mean the entire sustainable performance of the organisation/plant, including:
meeting all regulatory requirements
conforming to all industry covenants, protocols and best practice guides
minimising ecological and environmental footprint of process, plant and product
maximising economic benefit of process plant and product to the organisation and the community
minimising the negative OHS impact on employees, community and customer
Client
Client may be:
internal or external to the designer’s organisation

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 for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
interpret features of plant and equipment and parameters to the brief or contract
advise client based on discipline knowledge and OHS and regulatory standards
research sustainability implications and current thermodynamic system design techniques
determine OHS, regulatory and risk management requirements
model and calculate using appropriate software and validation techniques
generate and evaluate a range of solutions for feasibility against selection requirements
evaluate and select most appropriate thermodynamic solution
communicate, negotiate and review with stakeholders and client throughout process to obtain agreement on proposal and sign-off on selection
document evaluation and selection with drawings, specifications and instructions.
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 a simulated working environment 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.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
