Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a Unit of Competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT

PERFORMANCE CRITERIA

1 Develop a maintenance program  for a sprinkler irrigation system 

1.1 Maintenance requirements for irrigation components and structures are established

1.2 Maintenance requirements for the irrigation site are established

1.3 The frequency of maintenance activities required are determined and a schedule is developed

1.4 Maintenance activities are costed out in terms of required staff, materials and equipment

1.5 OHS risks associated with the maintenance program are assessed and suitable controls implemented

1.6 The environmental impacts of maintenance activities are minimised

1.7 A system for reporting maintenance activities is developed

2 Supervise maintenance of sprinkler irrigation components

2.1 Maintenance checklists are developed for irrigation components

2.2 Component operation is systematically monitored and operating faults are identified and appropriate action taken

2.3 Abnormal operation or frequent and recurring breakdowns are identified, investigated and maintenance organised as required

2.4 Situations requiring expert advice are identified and specialist assistance sought in accordance with site procedures

2.5 Equipment condition is routinely reviewed to ensure and maintain efficient operations

3 Supervise maintenance of sprinkler irrigation structures

3.1 Maintenance checklists are developed for irrigation components

3.2 Structures are inspected as necessary to locate and evaluate defects

3.3 Appropriate repair methods are identified to ensure defect is repaired effectively

3.4 Structures are repaired or replaced according to requirements

3.5 Materials required for job are identified and organised as required to enable appropriate maintenance of components

3.6 Testing equipment  is maintained

4 Supervise pest and weed control in an irrigated area

4.1 Evidence of pests is assessed and integrated control measures appropriate to type and species of infestation are determined

4.2 Areas of weed infestation on irrigation works are located and species identified

4.3 Integrated control methods are selected to control pests and weeds

4.4 Control methods are scheduled at the optimum time with minimal damage to desired plants

4.5 Severity of infestations and records of treatments are maintained

5 Complete records of irrigation system maintenance

5.1 Records are maintained of maintenance activities

5.2 Results of maintenance works are assessed against the maintenance program

Evidence Guide

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:

  • develop maintenance procedures
  • supervise maintenance of irrigation components and testing equipment
  • supervise maintenance of irrigation structures
  • supervise maintenance of the irrigation area
  • record and report maintenance activities.

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.

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. 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.

Maintenance programs  may include:

preventative maintenance carried out at end of season or throughout the irrigation season, including the regular replacement of irrigation components.

Sprinkler irrigation systems  may include:

describe systems that use spray or rotor type sprinklers to distribute irrigation water at higher volume including pop-up sprinklers, fixed, and movable sprinklers (e.g. K Line and Ezy Shift).

Maintenance of testing equipment  may include:

replacing 'remove and replace' components; lubrication; working adjustments to tolerances; cleaning and storing; and completing usage records.
