Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Plans may include:
architectural and base building plans
interpretation of building services
specifications for an appropriate building.

Service components include:
beams
lights
mechanical
registers
ventilating.

Building services include:
air conditioning
data and communications
electrical
fire
gas
hot and cold water supply
mechanical
sanitary plumbing and drainage
stormwater
trade waste
ventilation.

Ducts and positioning may be affected by:
building stress zones
clearances
other services
positioning of reinforcing steel
pre and post-tensioning bars
regulatory requirements
required services location
slab thickenings.

Duct and penetration plan may include:
cast-in pipework
detail drawings of duct layout beam penetrations
floor plan showing all ducts and penetrations
highlighted potential problem areas or building set-out elements
scale dimensions and sizes for all ducts and penetrations to gridlines.

Penetrations are positioned to take into account:
branches
fire collars and their operation
junction
other services to fit within the duct.

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 provide evidence of:
coordinating hydraulic service plans to ensure compliance and resolution of clashes
selecting and applying appropriate techniques to prepare a penetration plan for a complex building project
complying with WHS regulations applicable to workplace operations
applying organisational quality procedures and processes
preparing detailed drawings for service risers
preparing elevation and plan details for sanitary stack connections within the duct
preparing a detailed drawing of a service penetrating a beam
preparing checklists for use in coordinating services
communicating 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 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.
