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 project-based assessment techniques fully replicate plumbing and services workplace conditions, materials, activities, responsibilities and procedures.

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

A person should demonstrate the ability to:

locate, interpret and apply relevant information, standards and specifications to install or modify distribution and range pipes

apply safety requirements throughout the work sequence, including the use of personal protective clothing and equipment

as a minimum, given the plans and specifications of an automated fire sprinkler system:

install distribution and range pipes to provide a free-flowing and leak-free water supply to at least three branches to design criteria and standards, ensuring correct identification of location, design and details of proposed installation

relocate two sprinklers in an existing system, including draining down the system

complete work, ensuring:

application of sustainability principles and concepts

correct selection and use of appropriate processes, tools and equipment

completion of work to specification

compliance with regulations, standards and organisational quality procedures and processes

effective communication with others

safe work practices.

Context of and specific resources for assessment

Assessment of this unit:

must be in the context of the work environment

may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills

must meet relevant compliance requirements.

Resource implications for assessment include:

an induction procedure

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

safety data sheets, job safety analyses and safe work method statements

research resources, including industry-related systems information.

Method of assessment

Assessment for this unit must verify the practical application of the required skills and knowledge, using one or more of the following methods:

direct observation of tasks in real or simulated work conditions

questioning to confirm the ability to identify and interpret the essential underpinning knowledge required for practical application.

Guidance information for assessment

This unit could be assessed on its own or in combination with other units relevant to the job function.

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.

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.

Required skills

communication skills to:

determine pipe installation requirements

enable clear and direct communication, using questioning to identify and confirm requirements, and share information

follow and give instructions

use and interpret non-verbal communication, such as hand signals

numeracy skills to apply measurements and calculations

planning and organisational skills to:

plan and sequence tasks with others

plan and set out work

problem-solving skills to:

determine and use safe draining down methods

report faults in tools, equipment or materials to appropriate personnel

reading skills to interpret drawings and specifications

teamwork skills to work with others to action tasks

technical skills to use tools and equipment required to install distribution and range pipes and related components

technology skills to:

access site-specific instructions in a variety of media

use mobile communication technology

writing skills to complete workplace checklists and forms

Required knowledge

characteristics and application of different pipe fittings and fixture supports, including fixing and joining techniques

excavation processes and procedures required for installation of below-ground pipework

levelling and alignment processes to ensure correct installation of pipework

materials required to install distribution and range pipes

processes for calculating material requirements

properties and characteristics of water, including pressure and flow rates

relevant statutory and authority requirements relating to installing distribution and range pipes

requirements of job safety analyses (JSA) and safe work method statements (SWMS)

SI system of measurement

sources of relevant information relating to pipe installation requirements
