interpret site specifications and drainage system plans

set out drainage system works

measure materials

level and align earthworks

use equipment, tools and machinery

implement and follow relevant enterprise OHS and environmental policies and 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 (1) be applied?

Written, oral and telecommunication of ideas and information with the work group, supervisor, contractors or consultants, relating to installation activities and problems.

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

Enterprise work procedures and site and drainage system plans should be consulted, interpreted and applied to co-ordinate installation activities with further clarification sought from the supervisor when necessary.

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

Co-ordinating work activities for the work group, contractors and self, prior to and during the installation program.

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

Facilitating and leading work group members to complete the installation to specification.

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

Measuring materials and interpreting specifications for the drainage installation.

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

Dealing with problems imposed by site characteristics or when the system operation doesn't meet specifications.

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

Applying design specifications, communicating and keeping records.

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 drainage systems may apply to this standard?

Drainage systems may include surface drains, culverts, mole drains, sand slit, sub-surface traps, pit and trap systems, dune and swale systems, reed beds, water-recycling pumps and baffles.

What enterprise work procedures may apply to this standard?

Work procedures may include supervisors oral or written instructions, installation program, enterprise standard operating procedures (SOPs), specifications, routine maintenance schedules, work notes, product labels and Material Safety Data Sheets (MSDS), manufacturers service specifications and operators manuals, waste disposal, recycling and re-use guidelines, and OHS procedures.

What materials may be required to install a drainage system?

Materials may include drainage system components, glues, welds, construction materials for drain surfaces and slopes, and backfill materials.

What tools, equipment and machinery may be required?

Tools, equipment and machinery may include surveying and levelling equipment such as automatic level, laser level, dumpy level, Cowley level, staff, boning rods, pegs, notebook, pencil and calculator; hand tools such as rakes, shovels, spades, rollers, wheelbarrows, hoses and hose fittings; machinery such as bobcats, ditch witches, backhoes, front-end loaders, graders, mechanical rollers, trucks, hydraulic trailers, and tractors and 3-point linkage equipment; pumps and pump fittings; and fitting and welding tools appropriate to the drainage system.

What OHS hazards may be associated with the installation of drainage systems?

Hazards may include disturbance or interruption of services, solar radiation, dust, noise, soil and waterborne micro-organisms, chemicals and hazardous substances, manual handling, moving vehicles, machinery and machinery parts, uneven surfaces and flying and falling objects.

What safety equipment may be required?

Safety equipment may include signage and barriers.

What PPE may be required to install drainage systems?

PPE may include hat, boots, overalls, gloves, goggles, respirator or face mask, face guard, hearing protection, sunscreen lotion and hard hat.

What OHS requirements may be relevant to this standard?

OHS requirements may include identifying hazards, assessing risks and implementing controls, cleaning, maintaining and storing tools, equipment and machinery, appropriate use of PPE including sun protection; safe operation of tools, equipment and machinery, safe handling, use and storage of chemicals and hazardous substances, correct manual handling, basic first aid, personal hygiene and reporting problems to supervisors.

What environmental implications may be associated with the installation of drainage systems?

Restructuring and creation of slopes for drainage purposes may affect the run-off and flow rates of stormwater and excess irrigation water from the site, which may have beneficial or adverse impacts on the external environment. Drainage systems may also enable the enterprise to store and recycle storm and grey water for re-use within the enterprise, thereby reducing detrimental impacts on the external environment such as salinisation, waterlogging and erosion.

How may a clean and safe work area be maintained?

Tasks may include disabling unused tools, equipment and machinery and storing neatly out of the way of installation activities; safely storing materials on site; using signage and safety barriers during construction and removing them after activities are completed, and swiftly and efficiently removing and processing debris and waste from the work area.

What services may need to be located?

Services may include water supply, gas, power (electricity), telecommunications, irrigation, stormwater and drainage.

What waste material may be relevant to this standard?

Waste material may include unused construction and excavated materials, and plant debris, litter and broken components.

Plant-based material may be mulched or composted, plastic, metal, paper-based materials may be recycled, re-used, returned to the manufacturer or disposed of according to enterprise work procedures.

Waste may be removed to designated areas for recycling, reuse, return to the manufacturer or disposal.
