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. 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.
Work requirements may include:
location and extent of job
risk assessment recommendations
involvement of subcontractors
equipment specifications

water mains
services
valves
meters
pipes, including:
polyvinyl chloride (PVC)
polyethylene
mild steel cement lined
ductile iron cement lined
cast iron
copper
glass reinforced piping
fittings, including:
jointing systems for pipe types, e.g. gibault
tapping bands
tension bands
solvent joins
compression ring joints
bolted flanges
cathodic protection
structures, including:
meter pits
person access pits
regulators
erosion barriers
head walls
thrust blocks
Equipment and tools may include:
personal protective equipment
hand and power tools
lifting and winching equipment
mechanical excavation equipment
pneumatic and motorised equipment, including:
compressors
pneumatic spades and attachments
motorised cutting equipment
communication equipment
Legislative and organisational requirements may include:
relevant federal and state or territory legislation and regulations
codes of practice, associated standards and guidance material
documented organisational policies, manuals and induction programs
relevant community planning and development agreements, such as land care agreements

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 construct and install water distribution system assets by:
planning work and preparing work site safely
constructing and installing assets according to specifications and instructions
checking quality of work and ensuring water quality standards
clearing the work site
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 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
