soil boring & testing alternative
soil boring & testing alternative
(OP)
Because soil boring and sample testing are relatively expensive for determining how deep drilled piers should be, contractors sometimes drill a test hole as a cheap alternative. The correct depth is estimated by simply noting the type of soil coming up as a function of drilling depth.
Is this practice effective? It would seem that much information is missing and that there is much at risk.

RE: soil boring & testing alternative
Soil testing in my area runs from $2000-$5000 for most of the buildings I am involved with. The higher prices are for larger buildings (require more test holes) or for buildings that fall into the essential type category (hospitals, etc.). These projects run from $500,000 to $15,000,000. The cost of doing soil exploration is negligble when compared to the overall cost.
If I was in a position that I would have to follow the procedure you are asking about, I would find the geotechnical engineer who has done explorations in the vicinity and this still would make me very nervous.

I wouldn't let the contractor engineer a project that required piers, why would I let him do the geotechnical?

Good luck

Cost of drilling is peanuts compared to cost of litigations and trying to fix structures.
My two cents worth
