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!

Design production bores for multiple aquifer systems

  1. Determine most appropriate construction methods from the reading and interpretation of all available documented information and ensure relevant procedures and standards are adhered to
  2. Design the bore to ensure the exclusion of unsuitable waters and to prevent the inter-mixing of aquifers with different water quality or Standing Water Levels
  3. Select a bore site that will prevent contamination and minimise interference with other bores and that is safe with respect to potential occupational health and safety hazards
  4. Select likely water entry mechanism from the formation to the bore such as open hole, slotted casing screens, gravel packs
  5. Calculate appropriate artificial pack design parameters and recommended annular thicknesses required
  6. Undertake calculations to determine appropriate screen design parameters (e.g. diameter, length, aperture size)
  7. Plot and interpret sieve analysis results onto graphs
  8. Select appropriate bore/surface casing for the anticipated ground/water quality and pressure conditions and any construction requirements
  9. Ensure all necessary materials anticipated for the job are available and on site prior to commencement of construction phase
