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.
Organisational guidelines and standards may include:
federal and state legislation
codes
national guidelines
environmental protection agencies
OHS agencies
Pipeline system may include:
potable water pipelines
recycled water pipelines
gravity sewer pipelines
rising sewer pipelines
pressure sewer pipelines
vacuum sewer pipelines
service connections
appurtenances
maintenance structures

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
The candidate should:
perform each task outlined in the elements consistently and in a representative range of contexts
meet the performance criteria associated with each element by employing the techniques, procedures, information and resources available in the workplace from those listed in the range statement
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The candidate should demonstrate the ability to manage pipeline construction including:
interpreting design drawings, project documentation and relevant national, WSAA and water agency codes, supplements, specifications and product lists
applying quality principles to pipeline construction
ensuring the safety of people
applying environmental management principles to pipeline construction
installing pipes and service connections
installing appurtenances and maintenance structures
installing pipe embedment and support
installing trench fill
acceptance testing
disinfecting water supply pipelines
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
workplace specific equipment and technology
supervision and experienced team members to provide observations, feedback and third party reports
enterprise operating procedures and work allocation
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 require 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 only taken at the point 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 projectbased 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.
Method of assessment
The following methods are suggested:
assessment in the workplace or in a simulated workplace and under the normal range of workplace conditions
assessment should also be conducted in conjunction with aspects of technical competencies that are consistent with the work environment
Techniques for gathering evidence of competency may include:
observation of performance
written and/or oral questioning to assess knowledge and understanding
completion of workplace documents and reports produced as part of routine work activities
third-party reports from experienced practitioners
completion of performance feedback from supervisors and colleagues
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.
