Required knowledge

Required knowledge for this unit is

application of Australian and New Zealand standards and manufacturer specifications

common terminology and definitions used in design of complex nonsolar heated water systems

installation methods and hazards identified in relation to devices and systems used according to Australian and New Zealand standards and other codes or standard operating procedures

nature of materials used and effects of performance under various conditions

workplace safety requirements including relevant statutory regulations codes and standards

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 principles used to design complex nonsolar heated water systems

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

evaluating and documenting design parameters including client regulatory manufacturer and Australian and New Zealand standard requirements for a range of heated water supply and distribution systems

planning and detailing system components including

tempering valves

manifolding systems

insulation requirements

flow and return systems

complying with OHS regulations applicable to workplace operations

applying organisational quality procedures and processes within context of designing complex heated water systems

designing and sizing a range of heated water supply and distribution systems

designing and sizing a range of circulating systems

sound preparation of plans for a range of heated water supply and distribution systems

sound preparation of a specification for a heated water supply and distribution system

sound preparation of a testing and commissioning schedule

preparing an operation and maintenance manual

interactive communication with others to ensure safe and effective work site 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 working practices and addressing hazards and emergencies

material safety data sheets

research resources including industry related 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
