Those shims will eventually rot and that wall is going to eventually come down an inch. That temporary beam support was concerning as well. I wish you had showed us the point load support in the center of the structure where those two floor systems are being supported. Are they using a couple of 2-by material there?

I just still get a kick out of the fact you just casually walking around with a camera pointing at things after the guys have left for the evening. I just find that funny..no offense.
