Elements and Performance Criteria

The Range of Variables defines the different contexts, work environments and parameters governing the performance of this unit of competency. The variables chosen in training and assessment will need to reflect local industry and regional contexts.

What is the industry standard for design measures and structures?
Australian Rainfall & Runoff 1987.

Which industry sectors may be included?
Local government, urban, civil construction, forestry, extractive industry, rural, natural resource management.

Which industry people may be included?
Site engineers, project managers, advisers, consultants, earthmoving contractors, site supervisors, forest supervisors of foresters.

What types of measures designed may be included?
Sediment basins, containing banks, waterways, run-off control structures, revegetation, rural road and track drainage structures, top soil stripping, stock piling and respreading, silt fencing, hay bales, raised pondage around drop inlet drains, netting windbreaks, watering for dust control, dams, flumes, pipe structures, drop structures, diversion banks, catch drains, graded banks.

What evidence is required to demonstrate competence for this standard as a whole?
Competence in designing control measures and structures requires evidence that designs and specifications have been prepared and documented according to enterprise guidelines and industry best practice. The skills and knowledge required to design control measures and structures must be transferable to a range of work environments and contexts. For example, this could include different measures and structures, environments and locations.
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 unit are listed below:

Relevant environmental, planning and groundwater legislation.
Erosion control and design principles.
Soils and soil formation.
Levels and levelling.
Earthmoving principles.
Total catchment issues.
Legal requirements - permits.
Environmental issues.
Managing peak water flows.
Subsurface and surface drainage principles and systems.
Awareness of the limitations of design aids provided for industry.

What specific skills are needed to achieve the performance criteria?

To achieve the performance criteria, some complementary skills are required. These skills include the ability to:

Identify measures to be designed.
Apply design procedures.
Prepare specification schedule.
Cost and provide recommendations.
Collaborate with planner.
Use computer design programs.

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.

Essential Assessment Information
For information about

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.
Communicating ideas and information
By discussing control measures and structures unit at meetings, or formally in writing with clients and stakeholders. (3)

Collecting analysing and organising information
Designing control measures and structures will require detailed information to be collected, analysed and organised by research and consultation. (3)

Planning and organising activities
Designing control measures and structures requires following industry best practice design processes and procedures. (3)

Working with others and in teams
Designing control measures and structures will require development and management of work teams to achieve outcomes. (3)

Using mathematical ideas and techniques
Complex mathematical techniques relating to design and construction could be applied. (3)

Solving problems
While Designing control measures and structures, technical, organisational and cultural problems may arise requiring complex solutions. (3)

Using technology
Design and information presentation technology may be required. (3)
