I have an existing single story home, approximately 20 years old. The floor construction is wood engineered joists, supported by steel I beams, supported by hollow masonry blocks (4 tall) sitting on a concrete footing. I'm considering putting on a second story, and I've done the calculations on the beams and the spacing on the supports is more than adequate for two stories. My question is about the block piers. Should they not be filled with concrete and possible a rebar in each void?
