2. I'd like to fix the bottom couple of floors of the building so they don't move.
3. in places the girders are passing through the concrete. the binding doesn't seem to be working well.
4. there are a couple of fragments floating in the air. need to get rid of those.
1 and 2
You can use PhysX Bind, and check "ground", so the lower parts of the buildings are stick to the ground (with distance you can define how many floors you want)
3) I'd have to see the Flow in order to see what's going on. It's probably because you selected "ignore starting penetrations" so you avoid getting everything explode. I can't see simple solution for that. If possible, make sure non of the geometry is overlapping at the start of simulation. If your girders are overlapping with rest, maybe try to boolean or something... I repeat.. if you want as clean simulation as possible, you should first try making geometry in a way that nothing overlaps...
4) I don't see any of them floating in the preview, but it's probably because of PhysX bind. In the breaking rollout you can check that binds are broken after certain distance is reached.
