Foundation issue
(OP)
Hello all;
We have a slight situation on our hands. We have a pre-cast column attaching to a pad footing, and the pre-cast column is poured already. They contractor has set the pad footing too high by a foot, and we don't have any piers. The pad footing is rather large, approx. 14' square by 27" thick (for shear). The load is approximately 450 kips. Rather than telling our contractor to remove the footing or repour the column, we said that we will investigate making the existing siuation work. We are looking at notching out the 12" height of the footing (leaving us still 15") for the width of length of the column, and somehow trying to transfer the bulk of the load back up to the top of the footing. We have extremely solid soil directly below us as well. Has anyone ever tried tackling something like this, or should I tell the guy to do it right? Thanks for all input.

If left as is, would it stick out of the ground?
RE: Foundation issue
Will the higher footing be exposed above grade? Does the bottom of the footing still meet the minimum depth set forth by the geotechnical engineering report? Why can't you cut 12" out of the column length? Sawing and cutting a 12" hole into the top of a footing is going to send energy and cracks all through the concrete and may disrupt the bond with the steel as well.
