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!

RIINHB329 - Conduct sonic drilling operations

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

Plan and prepare to conduct sonic drilling

  1. Obtain, interpret and confirm work requirements
  2. Access, interpret and apply documentation required to conduct sonic drilling operations and confirm work activity is compliant
  3. Identify and minimise environmental issues and potential hazards, and assess and address risks within scope of own role and according to workplace procedures
  4. Select and wear personal protective equipment required for work activity
  5. Communicate with other personnel at site according to work requirements and confirm briefings and handover details are communicated and received
  6. Determine drilling and casing diameters required, as determined by sampling requirements, instrumentation install and client specification
  7. Access, interpret and apply documentation required to determine casing diameter to match core barrel diameter
  8. Carry out prestart and start-up procedures according to manufacturer specifications and site requirements
