Piling Tolerances
Piling Tolerances
(OP)
Hi,
Would just like to get some feedback on the plumbness tolerances that are generally accepted for driven piles.
Thanks.

RE: Piling Tolerances
This is subject to modification. Piles in groups can deviate quite a bit more, as long as the piles are not interfering with each other and the pile cap can perform properly.
Oftentimes the real issue is the eccentricity of reaction. If a pile is not plumb, it must be determined what is out, either the toe or the head. Is the pile a single or part of a group? The issue usually becomes a problem of statics.
RE: Piling Tolerances
a.) How do you check plumbness of say a 60 ft pile driven into the ground?
b.) what if the pile is plumb at the top and sweeps?
c.) How are the tolerancecs decided? Do they reflect the design capacity vs. design load?
d.) what happens if the pile is found out of plumb? How do you corrrect it and who pays?
Note that as innocent as these questions seem, they have sparked heated debates and firece arbtrations for a very long time.
Any thoughts?
