How Do We Know – Part 4

How Do We Know – Part 4

In this last post about validation, we will talk about ways to validate that we are working on – namely potholing/excavation and our future test and training facility.  The clearest way to move from SUE Level B – geophysical techniques (that’s us) – to SUE Level A – visual inspection – is to uncover the structure.  This is expensive and time-consuming, but it will validate what our system produces.  We have not done this yet, because all the sites we have surveyed were operational and we could not arrange for potholing.  We are actively seeking opportunities to do this; contact us if you are planning a potholing project soon! To validate our results, we would need to not only uncover the structure, but also measure it’s depth below the same grade that we surveyed.  This requires some planning.

The other validation technique we are planning is a facility where we survey infrastructure before we bury it, giving us exquisite “ground truth” that we can then verify with our equipment.  This facility would include all sorts of different pipe materials, vaults, cables, and voids of different sizes located at different depths and in many different configurations.  This provides the best tests and evidence for how our process works.  This facility will also serve as our training facility for operators, giving them the opportunity to learn how to use our equipment with a known configuration.  This facility is planned to come online in the next 18 months (once we secure our next round of funding).
