Piles Driven in Wrong Location
Piles Driven in Wrong Location
(OP)
I understand that no pile driver is perfect, and that's why we typically (in our office) allow a tolerance of about 6" off of the original point where there pile was intended to be located.
My question is , how about 12" off? It's not the end of the world, some induced torsional forces, but if it was an issue, what the fix? drive another pile? I couldn't think of many other options.

Thanks,

Option 2 is drive an additional pile, whether it's just a bit further down the gb and the out of tolerance one is abandoned, or whether you use the mis-aligned pile and the new pile with a cap to provide support where it is required, that's your choice and is usually situation dependent.

Before you end up wasting time on trying to make an out of tolerance pile work always have a thought about how much it's going to cost you to engineer the fix and then do really irritating detailing versus just throwing in another pile with relatively straightforward detailing and effectively no extra engineering. On shallow to moderate depth piles where the equipment is already there, the extra pile is sometimes the cheaper option.

Thanks for the responses.
My go-to would b an additional pile. My issue is that they discovered this almost 2 weeks later, so no pile driver on site.
What would the torsional reinforcement look like? Say you had a 3ft wide Grade beam, then instead of the pile being centered, it was 12" to the left. How would you change the reinforcement? Additional stirrups?
