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.
