Required skills

Required skills for this unit are:

communication skills to:

confirm job specifications and client requirements

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

read and interpret drawings, specifications and documentation from a variety of sources

use language and concepts appropriate to cultural differences

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

maintaining piping systems

numeracy skills to apply measurements and calculations

organisational skills, including the ability to plan and set out work

specifying procedures to locate piping systems

teamwork skills to work with others to action tasks and relate to people from a range of cultural and ethnic backgrounds and with varying physical and mental abilities.

Required knowledge

Required knowledge for this unit is:

common terminology and definitions used in the specification of piping system maintenance procedures

nature of materials used and effects of performance under various conditions

principles of technology in the specification of piping system maintenance procedures

requirements of state regulatory authorities, Australian standards and manufacturer specifications, including hazards identified in relation to devices and systems used

workplace safety requirements, including relevant statutory regulations, codes and standards.

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:

specifying equipment and procedures to be used for the location of pipes and services

specifying pipe-freezing equipment and procedures

specifying sewer and drain camera equipment and procedures

specifying under-road boring equipment and procedures

specifying robotic sewer repair and chemical grout systems and procedures

specifying high-pressure drain cleaning equipment and 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.

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.
