RE: seaint Digest for 1 Jan 2012

Wow!!  The contractor needs to go back to contractor school. 
If you are close, you may be able wait and use the 90 day breaks to achieve the strength.  Normal concrete mixes using cement will continue to gain a lot of strength beyond the 28 days we normally specify.  The other approach may be to add carbon fiber strengthening.  Fyfe is a good source. 
Whatever course of action, I would put the contractor on the hook for paying for all of this.  Work the deal through your client.  The other approach is for the contractor to tear it all out and do it again per the specifications.

Yes I've already added a beam to correct  the deviations.
The surveyor was there during the drilling execution but it didn't help.
Now there is a new problem : 
the concrete grade I've received from the compression test laboratories of the concrete floor is under the codes request.
This is a floor of a pool and the beams were done under the floor level.
Adding thickness will increase the self-weight and the piles weren't with great spare in design.
Do you have some idea what to do with the fact that the concrete quality grade you've received is not matching with your design??
