Thanks for the help. The problem is that the spec was for end bearing (yes, bored) piles and the structural wanted a spec for friction but the soils report is already approved. The friction piles would be longer at this dia so there is a cost issue as well.
Thanks
again

My structural guy is concerned about cleaning out residual debris from the drilled holes for end bearing piles of 24 in dia. Does anyone know of a device/method for cleaning out the last of the spoils from holes too small for a person to fit down??
Thanks
