column bas shims
(OP)
We are putting up a 4 story building, simple framing. W8x67 is the largest col member size. Some of the piers are 1"1/2 too low. Can the columns be shimmed to compensate for this elevation change?
If we can shim up to 1"1/2 should the shims be comb type and welded together so as not to slip?

RE: column bas shims
Atre these all gravity columns? Any uplift or shear?
Shims welded together may be an option. Do you even need shims? Are the anchor bolts long enough?
Just extend the grout pad. Depending on its thickness, you may have to mix in pea gravel.

Are the anchor bolts taking any shear or tension? Do they have enough current projection to get nuts on (not likely, but you never know), or can they be extended with threaded couplers?
FWIW, I had a call last week saying that a whole row of footings on one of my buildings was cast 5" too low. Unfortunately, a lot of these columns were part of a braced framed system. Such is the way it goes sometimes. :)
