Evidence Required

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 who demonstrates competency in this unit must be able to, as a minimum provide evidence of the ability to:

design, size and document required pumping systems for the hydraulic services installation required for a high-rise mixed development building to a minimum of 29 floors, inclusive of a basement, to include fixtures on each floor level (fixtures are included in the basement) and a wide span project (such as a school or industrial complex) to include:

applying sustainability principles and concepts throughout the design of pump system

evaluating and documenting design parameters to relevant Australian standards, codes, and hydraulic system client, regulatory and manufacturer requirements

planning and detailing system components, including:

ancillaries

control panel

fittings

flow switches

mounting

piping

plinths

pressure switches

pump duty

complying with WHS regulations applicable to workplace operations

applying organisational quality procedures and processes

using appropriate calculations and computer software

developing a cost-benefit lifecycle analysis for a range of systems

preparing plans and specification

preparing a testing and commissioning schedule

preparing an operation and maintenance manual

communicating with others to ensure safe and effective work site operations

producing safety and emergency procedures.

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 off-site 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, including design brief drawings, specifications, codes, design concepts and construction schedules

tools and equipment appropriate to applying safe work practices, including computers, software and calculators

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 person's 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.
