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

This unit of competency could be assessed in the workplace or a close simulation of the workplace environment providing that simulated or projectbased assessment techniques fully replicate plumbing and services workplace conditions materials activities responsibilities and procedures

It may be assessed on its own or as part of an integrated assessment activity involving effective performance and application of drainage principles and detailing of system components used in the drainage industry

Critical aspects for assessment and evidence required to demonstrate competency in this unit

A person who demonstrates competency in this unit must be able to provide evidence of the ability to

design size and document the layout details including a specification for a high rise mixed development building to a minimum of floors inclusive of a basement to include fixtures on each floor level fixtures are included in the basement to include

using two methods of providing a cold water supply

a nondrinking supply system

a flush valve system

evaluate and document design parameters including client regulatory manufacturer and Australian standard and code requirements for a range of complex water supply systems

evaluate health risks associated with the drinking and nondrinking water supplies

apply regulatory manufacturer and relevant Australian standard and code requirements for a range of complex cold water distribution systems

plan and detail system components including

authoritys connection

backflow prevention requirements

fixtures and fitments

flush valves

meter assemblies

storage tanks

piping systems

pumps

comply with WHS regulations applicable to workplace operations

apply organisational quality procedures and processes

design and size cold water distribution and delivery systems

design and size flush valve systems

prepare a specification for the cold and nondrinking water distribution system

prepare a testing and commissioning schedule

prepare an operation and maintenance manual

apply correct design principles and techniques

apply sustainability principles and concepts throughout to achieve a star rating under the Green Building Council of Australia rating scheme

communicate with others to ensure safe and effective workplace operations

Context of and specific resources for assessment

This competency is to be assessed using standard and authorised work practices safety requirements and environmental constraints

Assessment of essential underpinning knowledge will usually be conducted in an offsite context

Assessment is to comply with relevant regulatory or Australian standards requirements

Resource implications for assessment include

an induction procedure and requirement

realistic tasks or simulated tasks covering the minimum task requirements

relevant specifications and work instructions

tools and equipment appropriate to applying safe work practices

support materials appropriate to activity

workplace instructions relating to safe work practices and addressing hazards and emergencies

material safety data sheets

research resources including industryrelated systems information

Reasonable adjustments for people with disabilities must be made to assessment processes where required This could include access to modified equipment and other physical resources and the provision of appropriate assessment support

Method of assessment

Assessment methods must

satisfy the endorsed Assessment Guidelines of the Construction Plumbing and Services Training Package

include direct observation of tasks in real or simulated work conditions with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application

reinforce the integration of employability skills with workplace tasks and job roles

confirm that competency is verified and able to be transferred to other circumstances and environments

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 with a decision on competency only taken at the point when the assessor has complete confidence in the persons demonstrated ability and applied knowledge

all assessment that is part of a structured learning experience must include a combination of direct indirect and supplementary evidence

Assessment processes and techniques should as far as is practical take into account the language literacy and numeracy capacity of the candidate in relation to the competency being assessed

Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties such as existing supervisors team leaders or specialist training staff
