Unit Descriptor

This unit of competency describes the outcomes required to inspect and assess asset maintenance and repairs and to produce plans for and monitor and report on maintenance and repair work completion. The ability to identify faults, gather data, interpret technical information, assess risks and produce technical work plans, costings and reports are essential to performance.

This unit covers the competencies previously covered in:

NWP334B, NWP335B, NWP336B and NWP337B.

Application of the Unit

This unit covers a generic competency for field staff with responsibility for ensuring that water collection, distribution, storage and transfer assets are regularly monitored and conducting scheduled maintenance and repair work on assets.

Evidence Guide

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 

The candidate should demonstrate the ability to inspect and assess asset maintenance and repairs and to produce plans for and monitor and report on maintenance and repair work completion including:

  • conducting operational and maintenance inspections
  • monitoring fault reports
  • collecting and analysing operational and mechanical data
  • identifying and assessing work methods effectiveness
  • planning investigations and repairs
  • developing repair procedures
  • assessing risks and specifying preventive methods
  • selecting equipment, materials, prefabricated components and fittings
  • monitoring repairs
  • inspecting completed repairs
  • completing workplace records

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/or 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 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, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed.
