Required knowledge: system hydraulics basics system layout environmental aspects of maintenance lock-out procedures for mechanical and electrical installations relevant utilities and service bodies communication systems work-related calculations hazardous materials handling landscape and ground structure of work area risk factors and potential hazards of maintenance processes equipment operation, capacity and limitations effects of weather and conditions on construction site or plant control systems pipes and fittings disinfection of systems and chemical usage. |
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package. | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The candidate should demonstrate the ability to conduct repair work on water distribution assets by: planning work and preparing work site performing repair tasks according to manufacturer specifications and organisational requirements ensuring system hygiene and water quality checking work, restoring work site, storing equipment and completing documentation. |
Context of and specific resources for assessment | Access to the workplace and resources including: documentation that should normally be available in a water industry organisation relevant codes, standards and government regulations. Where applicable, physical resources should include equipment modified for people with disabilities. Access must be provided to appropriate learning and assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed. Validity and sufficiency of evidence requires that: competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice a decision of competence should only be made when the assessor has complete confidence in the person's competence over time and in various contexts all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit. In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed. |
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. Add any 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. | |
