Description
This Unit covers the process of constructing and installing a surface irrigation system and defines the standard required to: establish the requirements of the system; implement operational procedures for the project; establish and organise resources; supervise on-site construction; and commission the system.
Notes
Elements and Performance Criteria
1 Develop and implement construction procedures
  • 1.1 Employment procedures and contract management procedures are developed
  • 1.2 Procedures for controlling and recording site deliveries are established

  • 1.4 OHS procedures are established, including risk assessment
  • 1.5 Client, authorities and agencies are notified of the schedule of works
  • 1.6 Procedures for dealing with environmental issues associated with construction work are determined
2 Interpret the surface irrigation system design for the site
  • 2.1 The purpose, scale and required output of the irrigation system is determined
  • 2.2 The landscape of the site is assessed
  • 2.3 Construction requirements are determined and verified with the designer
  • 2.4 Components are selected to meet design specifications and site requirements
3 Organise resource requirements
  • 3.1 Tasks and timelines are nominated with resources required for each
  • 3.2 Labour requirements are organised

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.
Surface irrigation systems may include:
any systems that apply water across the surface of a levelled or contoured area. These include furrow, border and basin irrigation.
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

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:
establish the requirements of the system
implement operational procedures for the project
establish and organise resources
supervise on-site construction
commission the system.
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.
