Re: Foundation piles deviations

        Sounds to me like you should just execute the contractor.
        A more practical solution, however, may well be to follow Irv Fruchtman's suggestion to design some grade beams to transfer the loads as needed.  The downside is that the weight of the grade beams may be substantial.  You may want to have the geotechnical consultant review the pile design or even conduct load tests to confirm that the new design is satisfactory.
        I would strongly recommend that you do NOT release any payment to the contractor (or sub contractor) until this issue is resolved.  The cost of correcting this will probably be substantial and the contractor could just take the money and run.
Regards, and Happy New Year,

Subject: Foundation piles deviations


I have a building in construction phase, as the designer, the contractor and the client are sending the as-made location of the foundation piles.

The piles were done by CFA Method, 70cm diameter, 15m depth.

Almost each of the pile was done in deviation from the original design location I'd designed, about 2% to 20%

Do you know a kind of rectification for this kind of installation errors, or just to execute some other ones?

Executing other ones will be very complicated; I'm looking for other smarter solutions.
