Elements and Performance Criteria

  1. Identify PE pipe materials as being suitable for specific pressure applications.
  2. Identify applications for alternative jointing technologies.
  3. Determine methods for handling, storage, transport and installation of PE pipeline components.
  4. Identify appropriate service connection and repair techniques.
  5. Assess quality of completed installation by determining appropriate testing and commissioning procedures.

Required Skills

This describes the essential skills and knowledge and their level required for this unit

Knowledge and understanding of PE materials and pipeline components as described in national standards to recognise suitability for specific installation and to establish work instructions

Knowledge of specific job requirements necessary to determine detailed work instructions and the ability to implement requirements to attain required quality outcomes

Knowledge as a basis for solving processing and material problems including

identify types of materials and components being used

establish specific job needs

set up and maintain safe working environment

set up and maintain required storage handling and transport procedures

establish installation requirements

perform jointing and installation to meet required quality levels

identify and rectify fault causes arising from application and component variables

establish completion test requirements

Language literacy and numeracy requirements

Read material which is sequenced for instructions explanations information or opinions

Write short and simple messages about routine tasks or activities or complete forms

Use handson reallife materials and picturesdiagrams based on personal experience and prior knowledge

Use several pieces of related mathematical information

Read write and speak whole numbers and money sums recognise and interpret simple fractions decimals and percentages use simple data grid references

Use simple grammatical forms and vocabulary to give instructions give explanations ask questions and express viewpoints

Clarify intended meaning by asking for repetition when listening and varying speed and changing tone or emphasis when speaking

Use strategies such as providing verbal and nonverbal feedback in order to show interest or attitude

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge the range statement and the assessment guidelines for this training package

Overview of assessment

A holistic approach should be taken to the assessment

Assessors must be satisfied that the person can consistently perform the unit as a whole as defined by the Elements Performance Criteria and skills and knowledge

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that the installation meets the requirements of the standard

Assessment method and context

Assessment will occur using industrial PE pipes and installation equipment and will be undertaken in a worklike environment

Competence in this unit may be assessed

using an appropriate industrial equipment situations and polymers

in a situation allowing for the generation of evidence of the ability to recognise anticipate and respond to problems

by using a suitable simulation andor a range of case studiesscenarios

through a combination of these techniques

In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practicalsimulation or similar assessment Assessors need to be aware of any cultural issues that may affect responses to questions

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy language and literacy capacity of the assessee and the work being performed

Specific resources for assessment

This section should be read in conjunction with the Range Statement for this unit of competency Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation A bank of case studiesscenarios and questions will also be required to the extent that they form part of the assessment method Questioning may take place either in the workplace or in an adjacent quiet facility such as an office or lunchroom No other special resources are required

Access must be provided to appropriate learning andor assessment support when required Where applicable physical resources should include equipment modified for people with disabilities


Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any 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.

Where reference is made to industry codes of practice and/or Australian/international standards, the latest version must be used.

Context

This competency unit includes the installation of relevant elements of polyethylene (PE) pressure pipeline components. The end applications include pipelines used for transmission of gaseous and water based fluids.

It also includes the operation of alternative jointing procedures, service connections repairs using all relevant ancillary equipment.

Specifications include national standards for materials (AS/NZS 4129, AS/NZS 4130, AS/NZS 2566 and AS/NZS 2033), workplace specifications and instructions, and government codes and regulations.

Procedures

All operations are performed in accordance with procedures.

Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards. These may include:

AS/NZS 4129

AS/NZS 4130

AS/NZS 2566

AS/NZS 2033.

Tools and equipment

This competency includes use of equipment and tools such as:

mechanical and thermal jointing equipment, ancillary jigs and fixtures.

measurement devices, including pressure gauges, times, temperature probes, calipers and computer based monitors

calculators

service connection and repair equipment and products

relevant safety equipment

comprehensive work instructions.

Hazards

Typical hazards include:

hazardous cleaning fluids

pipe material handling

heavy stationary and moving machinery

cutting and heating components.

Problems

'Anticipate and solve problems' means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.

Typical process and product problems may include:

variable PE materials, and pipes and components as supplied

equipment malfunction or wear and tear

variable field site conditions

limitations in available data on specific job requirements.
