Description
This unit covers the process of laying irrigation and/or drainage pipes and defines the standard required to: set out and excavate trenches using manual equipment and a machine operator; check trench depth and grade; lay bedding materials; position irrigation and/or drainage of varying types and sizes; install pipe joints and fittings to job specification.
Notes
Elements and Performance Criteria
1. Plan and prepare job
  • 1.1. Materials required for the job are transported to the location and stacked in a safe position.
  • 1.2. Tools, equipment and machinery are selected consistent with the requirements of the job.

  • 1.4. Personal Protective Equipment (PPE) is used and maintained according to procedures.
  • 1.5. Occupational Health and Safety (OHS) hazards are identified and safety concerns reported to the supervisor.
2. Set out and excavate trenches
  • 2.1. Location and depths of trenches is determined from job drawings.
  • 2.2. Trench location is set out with pegs and string line and clearly marked with appropriate marking material.
  • 2.3. Manual support is provided to machine operator with excavation of trenches, shoring or battering in accordance with OHS requirements.
  • 2.4. Trenches are cleaned out by hand and corners left square.
  • 2.5. Trench depths and grades are checked for conformity to job requirements.
3. Lower and position pipes
  • 3.1. Bedding materials are laid and consolidated to specified depths and grades.
  • 3.2. Pipes are installed/lowered into position with appropriate mechanical equipment according to specifications.
  • 3.3. Pipe joints and fittings are installed to job specification.
  • 3.4. Pipes are back filled to specifications and cover left level with surrounding ground.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:
set out and excavate trenches using manual equipment and a machine operator
check trench depth and grade
lay bedding materials
position irrigation and/or drainage of varying types and sizes
install pipe joints and fittings to job specification.
Context of and specific resources for assessment
Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.
