Description
This unit of competency describes the skills and knowledge required to identify irrigation design key features, define the placement and function of irrigation system, mark out structures and component locations, estimate earth moving requirements, select pumps and system components, and develop staff instructions for interpretation and application of an irrigation design for an installation site.The unit applies to individuals who apply specialised skills and knowledge to the interpretation and application of irrigation designs and have responsibility for the output of others. This includes applying and communicating non-routine technical solutions to predictable and unpredictable problems.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Identify the key features on an irrigation design
  • 1.1 Identify and apply commonly used symbols and abbreviations on plans
  • 1.2 Identify and apply common irrigation terms used on plans
  • 1.3 Identify key features of irrigation plans, elevations and sections
  • 1.4 Identify scale, elevations and sections from drawings
2. Define the placement and function of the irrigation system
  • 2.1 Interpret the plans, drawings and specifications for the irrigation design
  • 2.2 Identify the proposed purpose and capacity of the irrigation system
  • 2.3 Position the designed system in relation to the landscape of the site
  • 2.4 Identify environmental impacts of the irrigation system, and its installation
  • 2.5 Prepare as constructed drawings
3. Mark out structures
  • 3.1 Mark the boundaries of the site
  • 3.2 Identify existing irrigation infrastructure on the site
  • 3.3 Identify electricity and communications infrastructure on the site plan and develop safety procedures
  • 3.4 Mark out on site electricity and communications infrastructure
  • 3.5 Mark out on site remnant vegetation to be retained
  • 3.6 Identify and peg out on site proposed pipelines
  • 3.7 Identify and peg out on site proposed irrigation structures
4. Estimate earth moving requirements for construction
  • 4.1 Interpret earthworks drawings and take site levels
  • 4.2 Estimate the amount of earth to be relocated or removed from the site
  • 4.3 Confirm the sequence of earthworks and communicate to relevant staff
  • 4.4 List and quantify materials required for irrigation structures
  • 4.5 Verify construction requirements with designer
5. Select pumps and system components
  • 5.1 Interpret design specifications for water volume, pressure and delivery pattern required
  • 5.2 Select pumping system based on design specifications
  • 5.3 Select irrigation system components based on design specifications
  • 5.4 Verify component selection with designer
6. Mark out locations of all components
  • 6.1 Define the sequence of operations for installation
  • 6.2 Identify the delivery and storage area for components
  • 6.3 Identify the placement of all components
7. Develop instructions for staff
  • 7.1 Identify potential environmental hazards and strategies to minimise risks in instructions
  • 7.2 Document the sequence of activities and work duties
  • 7.3 Discuss workplace health and safety hazards and risks and safe working practices to manage risks with staff
  • 7.4 Provide a construction schedule to staff
