Required Skills
Required skills |
Required skills include: interpreting client requirements and specifications determining performance aspects of systems sizing pipes minimising system heat losses selecting major system components and materials using manufacturers data selecting appropriate heating equipment evaluating piping configuration using relevant software tools effectively interpreting drawings and specifications communicating effectively with others communicating technical and procedural requirements to others documenting technical information and designs dealing effectively with unexpected situations working in teams and with others |
Required knowledge |
Required knowledge includes: heating techniques, including relative advantages and disadvantages of: heat pumps boilers and hydronic systems, including underfloor systems gas electric solar solid fuel system configuration piping configuration, including: standard materials and sizes sources of information (e.g. catalogues) system pipe sizes WHS and environmental requirements relevant to heating systems |
Evidence Required
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: implement WHS workplace procedures and practices, including the use of risk control measures as specified in the performance criteria and range demonstrate essential knowledge and skills to design heating systems demonstrate competence within a timeframe typically expected of the discipline, work function and industrial environment demonstrate the design of a heating system consistently for different applications. |
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, 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. |
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 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 not only able 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. |
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. 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. | |
WHS requirements | WHS requirements include: legislation protective equipment material safety management systems hazardous substances and dangerous goods code local safe operation procedures awards provisions |
Environmental requirements | Environmental requirements include: relevant legislation, regulations and codes correct handling and disposal of liquid and solid waste elimination or minimisation of gas, fume, vapour and smoke emissions, including fugitive emissions dust elimination, minimisation and control minimisation of energy and water use elimination or control of excessive noise use and recycling of refrigerants |
Appropriate personnel | Appropriate personnel may include: supervisor leading hand foreman manager engineer technician trainer mentor team member customer client |
Resources | Resources may include: scientific calculator componentry catalogues technical charts and tables design brief suitable software |
Enterprise procedures | Enterprise procedures may include: the use of tools and equipment instructions, including job sheets, plans, drawings and designs reporting and communication manufacturer specifications operational procedures industry procedures |
Equipment | Equipment may include: computer workstation and software, either stand alone or networked test apparatus appropriate tools of trade, equipment and materials |
