Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

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

Competence in implementing a retaining wall project requires evidence that a person can prepare a project site, set out a retaining wall project, build a retaining wall, and complete a project according to design parameters.

The skills and knowledge required to implement a retaining wall project must be transferable to a different work environment. For example, this could include different retaining situations, different retaining wall materials, and different job complexities.

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:

landscape retaining wall materials

landscape retaining wall construction techniques

set out techniques

work schedule programming

possible causes of disruption to work activities and their effect on quality and time schedules

methods and practices for maintaining and repairing retaining walls

the range, use and availability of materials, equipment and machinery that may be required for the project

OHS issues, legislative requirements and codes of practice.

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 documentation associated with retaining wall projects

calculate material and resource requirements

co-ordinate a team to achieve optimum performance

communicate with personnel at all levels

document results clearly and concisely

perform an OHS risk assessment.

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 (2) be applied?

Ideas and information may need to be communicated with the client/supervisor, such as regular reporting.

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

Information on retaining wall project may need to be collected, analysed and organised according to the scope of work required.

3. How are activities planned and organised (2)?

Activities may need to be planned and organised to ensure that the project meets timelines.

4. How can team work (2) be applied?

Team work may be applied to ensure that retaining wall project is undertaken according to schedule.

5. How can the use of mathematical ideas and techniques (2) be applied?

Mathematical ideas and techniques may be applied when organising, calculating materials, determining falls and setting out site.

6. How can problem-solving skills (2) be applied?

Site contingencies, personnel difficulties, timeline failures, assessing hazards and identifying controls, may require problem-solving skills.

7. How can the use of technology (2) be applied?

Technology may be used to set out and level site.

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.

Retaining wall projects include all modular concrete, timber, brick, dry stone and mortared block.

What resource requirements are likely to be identified?

Resource requirements may include base materials, sub-surface drainage materials, retaining wall components, levelling equipment and powered tools, and other equipment associated with construction.

What might be the environmental implications of proposed work site activities?

Environmental implications may include risk of contamination of soils, water, or adjoining property through fuels flowing into drains and water sources, or changes to drainage patterns. Compliance with local, State/Territory, and Commonwealth environmental legislation is required.

What OHS hazards may apply to work site activities?

Hazards may include disturbance of services, solar radiation, dust, noise, through traffic, uneven surfaces and holes, moving machinery and machinery parts, powered equipment and hand tools, hazards from use of hired equipment (untrained staff), and overhead hazards including powerlines.

What PPE is likely to be selected?

PPE will be determined by the type of activity being undertaken and may include work boots, gloves, overalls, sun hat, sunscreen lotion, and hearing or eye protection.
