Evidence Guide

What evidence is required to demonstrate competence for this standard as a whole ?

Competence in supervising on site irrigation installation and construction work requires evidence that a person can organise the supply and installation of materials and equipment, supervise on-site operations, and administer progress claims/payments. They must also communicate effectively with on-site labour, suppliers and the client, and implement and monitor relevant OHS and risk management procedures.

The skills and knowledge required to supervise on site irrigation installation and construction work must be transferable  to a different work environment. For example, this could include different irrigation systems, reasons for irrigation, environments and enterprise procedures.

What specific knowledge is needed to achieve the performance criteria ?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts, and to deal with unplanned events. The knowledge requirements for this competency standard are listed below:

communication procedures for on site labour and authorities

safety procedures and quality assurance programs

local government regulations

on-site contract provisions

projected costs

environmental impacts of irrigation system installation using water from any ground or underground source

relevant enterprise OHS procedures.

What specific skills are needed to achieve the performance criteria ?

To achieve the performance criteria, appropriate literacy and numeracy levels as well as some complementary skills are required. These include the ability to:

communicate effectively on site

read plans and specifications

order materials and equipment to meet schedule

administer the contract on site

supervise construction operations in the most efficient sequence

identify adverse environmental impacts of irrigation installation activities and take appropriate remedial action

comply with statutory requirements

follow relevant enterprise OHS and environmental procedures.

What processes should be applied to this competency standard ?

There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies , although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.

1. How can communication of ideas and information  () be applied?

Communicating with on-site labour, client and suppliers.

2. How can information be collected , analysed and organised  ()?

Reading and interpreting plans and schedules.

3. How are activities planned and organised  ()?

Co-ordinating installation and construction activities.

4. How can team work  () be applied?

Co-ordinating on-site labour.

5. How can the use of mathematical ideas and techniques  () be applied?

Monitoring schedules, work progress and materials consumption.

6. How can problem -solving skills  () be applied?

Responding to unforeseen circumstances on site.

7. How can the use of technology  () be applied?

Using relevant materials ordering technology.

Are there other competency standards that could be assessed with this one ?

This competency standard could  be assessed on its own or in combination with other competencies relevant to the job function.

There is essential information about assessing this competency standard for consistent performance  and where and how it may be assessed , in the Assessment Guidelines for this Training Package. All users of these competency standards must have access  to the Assessment Guidelines . Further advice may also be sought from the relevant sector booklet .

Range Statement

Range of Variables 

The Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment requirements may depend on the work situations available

To which systems does irrigation installation and construction  relate?

These may include gravity fed and pressurised systems.

How might site instructions be recorded ?

Instructions may be recorded using a diary, telephone log and/or memos.

What OHS  requirements may be relevant to this standard?

OHS procedures may include identification and reporting of hazards to health and safety, risk assessment procedures and implementation of risk control measures, safe operation of machinery and equipment, safe manual handling procedures, selection, use and maintenance of relevant personal protective clothing and equipment, safe procedures for working at heights and for outdoor work, including protection from solar radiation, dust and noise.

For more information on contexts, environment and variables for training and assessment, refer to the Sector Booklet.
