Qualification -
Unit of Competency RTE2603A - Lay irrigation and/or drainage pipes
Description This competency standard covers the process of setting out and excavating trenches using manual equipment and a machine operator, laying bedding materials, and positioning irrigation and/or drainage of varying types and sizes under routine supervision. Laying pipes requires the ability to read and interpret scale drawings, measure trench width, depth, grade and location, use power tools and hand tools, and work safely to instructions. This unit requires knowledge of irrigation and/or drainage pipes, types and sizes, hand and power tools and equipment, bedding and backfill materials and handling methods, hand signals for communication, and relevant OHS issues and procedures.NB: This unit does not include operating excavation machinery such as trench diggers or ditch witches, but does include the use of mechanical equipment for lowering irrigation and/or drainage pipes.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

Competence in laying irrigation and/or drainage pipes requires evidence that a person can set out and excavate trenches, check trench depth and grade, lay bedding materials, and position pipes to job specifications and supervisor instructions. The skills and knowledge required to lay pipes must be transferable to a different work environment. For example, this could include different pipes types and sizes, soil types and enterprises.

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:

workplace and equipment safety requirements for excavating, filling trenches and laying pipes, including relevant legislation regulations and codes

irrigation and/or drainage pipes, types and sizes

hand and power tools and equipment

bedding and backfill materials and handling methods

scale drawings for laying irrigation and/or drainage pipes

hand signals for communication

OHS issues and procedures related to trenching and pipe laying

Quality Assurance procedures for excavating, filling trenches and laying pipes.

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:

read and interpret scale drawings and specifications

use hand signals for communicating with machine operator

measure trench width, depth, grade and location

level cover with existing ground

use power tools and hand tools

handle materials safely

work safely to instructions.

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 (1) be applied?

Using hand signals to machine operator.

2. How can information be collected, analysed and organised (1)?

Checking depth and grade of trenches and meeting design specifications.

3. How are activities planned and organised (1)?

Selecting equipment, tools, materials and personal protective equipment.

4. How can team work (1) be applied?

Providing manual support to machine operator.

5. How can the use of mathematical ideas and techniques (1) be applied?

Pegging out trench locations.

6. How can problem-solving skills (1) be applied?

Lowering and positioning pipes.

7. How can the use of technology (1) be applied?

Using laser equipment to design grades.

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 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

What tools, equipment and machinery might be relevant to this competency standard?

These may include string lines, hammers, measuring tapes, automatic or manual levels, staves, optical squares, rakes, shovels, spades, rollers, trench digger, backhoe, polythene pipe layer, and fitting and welding tools.

What OHS requirements might be relevant to this standard?

OHS requirements include safe systems and procedures for the operation of machinery such as trench diggers and backhoes and other equipment, manual handling, selection and use of hand tools, selection and use of relevant personal protective clothing and equipment, and for working outdoors including protection from solar radiation, dust and noise.

What factors might affect trench location and trench depth?

Factors affecting the location and depth of trenching may include existing services such as power, water, and telephone, depth of cultivation for pasture improvement, existing plant and facilities such as roads and tracks, the susceptibility of soil to erosion or slipping during excavation or construction, and relevant legislation and/or regulations.

How might the grade be designed?

This may include manual and laser equipment.

What type of irrigation and/or drainage pipes might be used?

These may include concrete, metal, polythene or polyvinylchloride (PVC). The type and size of pipe will vary with the terrain, soil type and traffic load.

What fittings may be relevant to this standard?

Fittings may include valves, outlets, thrust blocks and connecting surfaces such as O-rings.

What environmental requirements might there be in the clean up phase of laying pipes?

Environmental requirements may include recycling or environmentally safe disposal of excess soil, debris and unwanted materials.

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

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
