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!

DEFCA316B - Supervise the construction of short-term roads or tracks

What evidence can you provide to prove your understanding of each of the following citeria?

Plan road or track

  1. Data relating to road requirements and restrictions is interpreted from instructions, expected time frame for usage and likely weather conditions.
  2. Assistance is sought to survey road location.
  3. Water courses and other ground obstacles are surveyed and their impact on road design is noted.
  4. Crossing or entry points for other roads and tracks are planned.
  5. Soil conditions are investigated to establish profile to sub-base level.
  6. Extent and depth of clearing and cutting are planned.
  7. Soil dumping or storage areas are planned to meet volume of soil to be removed, and access and restoration requirements.
  8. Construction plan is developed in accordance with design, resources, risks and environmental considerations.
  9. Availability of required road base and additional material is confirmed or material is ordered.

Instructions to Assessors

Evidence Guide

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to construct roads and track to a standard that they could be classified as allweather dirt roads and tracks capable of sustained heavy vehicle traffic.

The road or track must be able to be sealed without further construction.

Consistency in performance

Competency should be demonstrated over a time frame that encompasses all aspects of this Unit of Competency. Assessment need only be conducted supervising the construction of one road or track due to the high cost and complex nature of the task.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or in a simulated work environment.

Specific resources for assessment

Access to construction equipment and materials; communications equipment; suitable site; and construction team.
