Do you know a kind of rectification for this kind of installation errors, or just to execute some other ones?
Harold mentioned DFI. I didn't see anyone mention ACI 117, which contains Tolerances for concrete work including bored pile foundations. I think it's pretty complete.
As far as rectifying the problem, here in the states, "the contractor proposes and the engineer (as representative for the owner) disposes." In other words it's not for you to come up with remedial methods, it's for the contractor to propose them and you are responsible for acceptance.
The contractor SHOULD have enough money in the bank to hire his own engineer if he needs help with that, FWIW.
This habit of contractors to screw up and then expecting the OWNER'S engineer to fix his mess is absurd - and rather childish if I do say so myself.
Putting you on the spot, and shifting some of his liability for his mistake onto you, is more than absurd, it's insane. Don't fall for it.
