If I really understood this process, would have done all the demo before any of the building (just wall sheathing so far, but still).

Sunday: got the last couple of built-in shelves removed.

Used 4.5″ angle grinder with cutting disk for rivet reduction. A little bit scary with all the sparks and a full tank of gas, oh well. Here: A screw ground down until pliers could torque it.

Safety first.
