Pile design requirement
Pile design requirement
(OP)
Hello all:
For curiosity, what soil bearing capacity do you guys use as a benchmark for the need of piles in highly cohesive soil. Geotech is preparing soil report but I was wondering how does this play out when IBC allows for footing design assuming a 1500 psf without a soil report. This is for a new two story 5000 sf sfr close to a floodplain. Thanks

But I'm no geotech.
As an aside, it has been discussed a few times on this board. The geotech guys have been beaten down on fees to the point where a lot of the time they default to the IBC allowable values. This is because except in rare circumstances, 1500 PSF is easily achievable with standard construction practices.
If client's were willing to pay a geotech a proper fee (like they deserve in my eyes) you would likely get significantly better design values from them. Or at least you would have more confidence in the values used and ideally more useful recommendations to improve foundation performance.
