auger refusal standard
auger refusal standard
(OP)
Is there a standard for definition of auger refusal on rock when drilling? I have language in a workplan that states soil stabilization will occur to bedrock (known elevation) or auger refusal....the state came back wanting to define auger refusal. I seem to recall 6 inches in 15 minutes from my fieldwork but have no reference for that.

The shape and teeth of the auger will also influence the refusal.
Just to say that there is no standard for that !

One thing to consider: If the driller says it's auger refusal, it's auger refusal! If you were to say, "Nah, try some more" and something broke, you'd likely be on the hook for the repair. Let the driller do his/her job and use the data accordingly. Just make sure that your drilling inspector makes appropriate notes and documents the field conditions at the time of auger refusal. You do have a field inspector, eh?

On that basis, be very simple. Maybe something like "When no significant advance of the rotating drill bit occurs".
