Do you need to be a technical person to attend?

If you are someone that organises the Soil Resistivity measurement task but does not actually ‘do’ the field-work, then an appreciation of the task is sufficient. However, a reasonable level of practical knowledge is assumed if you ‘do’ the measuring yourself.

Why You Should Attend

In any design/installation – starting with a solid, reliable data-set that you have confidence in, is super important. So, understanding what a ‘good’ set of measurements looks like verses what an erroneous set looks like is critical.


All safety-related calculations are based on this fundamental piece of information – the soil model. Get this right and everything is golden but get this WRONG and the entire project can be based on misguided assumptions which can be expensive to reverse at best, and outright dangerous at worst!


So, learn where the errors can creep in and why. Learn the common mistakes to avoid so that your project, your tests, are technically secure when they fall under the spotlight of close scrutiny.
