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, provided that the simulated or project-based assessment fully replicates workplace conditions, materials, activities, responsibilities and procedures.

This unit could be assessed as an activity involving the production of pipe fabrication documentation for a range of fire sprinkler system design projects.

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 required skills and knowledge specified within this unit.

In particular the person should demonstrate:

the ability to:

read and interpret a range of design drawings

create, manipulate, save, file and share design drawings

an understanding of technical issues impacting on fire sprinkler systems designs

an understanding of installation risks and constraints impacting on pipe fabrication specifications for fire sprinkler systems

the ability to produce safe, efficient and cost-effective solutions and accurate drawings and documentation for pipe fabrication work for fire sprinkler systems, including:

wet pipe

deluge and drencher

dry pipe

pre-action

early suppression fast response (ESFR)

combination systems

the ability to produce safe, efficient and cost-effective solutions and accurate drawings and documentation for pipe fabrication work for fire sprinkler systems in a range of project types, including:

low-rise buildings

medium-rise buildings

high-rise buildings (over 25 metres)

buildings over 45 metres in height.

Context of and specific resources for assessment

Assessment of essential underpinning knowledge may be conducted in an off-site context. It is to comply with relevant regulatory or Australian standards' requirements.

Resource implications for assessment include:

design briefs, drawings, plans and specifications

copies of codes, standards, legislation and regulatory requirements

access to information and communications technology - hardware and software

access to manufacturer's information.

Method of assessment

Assessment 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.

Guidance information for assessment

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.
