Hello. I am getting ready to construct my new column footings for my crawlspace-to-basement project. The footings will support steel columns resting on 1/2" think baseplates as shown in the attached graphic. My assumption is that it is critical that I get the footing surface as flat and as parallel to the baseplate as I can so that the entire baseplate surface is resting on the concrete. I'm thinking of several ways to do this: Method #1: Form the concrete surface as level and flat as possible using a bubble level. Install the welded column assembly on top after curing and hope that I got it exactly right. Method #2: Form the footing as in #1 above, but position the baseplate and column separately and weld together in place (this allows the baseplate to adapt to the footing surface. Method #3: Install the welded column assembly on the cured footing as in #1, but apply a thin layer of epoxy or grout under the baseplate to provide an even surface for the baseplate to rest on. I'm curious how others would handle this. Is this really as critical an issue as I'm thinking or am I getting way too anal about this unnecessarily? Thanks in advance for any replies.
