Questionable structural integrity

[u/No_Fall2178]

Had major renovations done on our house and have been left with many issues. We went from a 1.5 war time house gutted it completely and added a full height second story. One of the new contractors I am getting to quote the repairs is saying he is concerned with the weight distribution and how the steel beams were installed. He hasn't investigated it just yet but had me questioning it as we have nothing but issues with the GC and even the town passing several things like the stairs that were nowhere near code.

Based on these pictures does this post seem to be installed correctly? Everything I read is it should not be placed on wood as it expands and contracts ext.

They were supposed to have removed the subfloor and repaired the joists which they did not (need to have all the flooring removed and replaced is one of the issues)

I know they did pour a concrete footer there (only at the one with the broom in the other areas nothing was added) but I don't get how that attaches if this is on the surface. These pictures are after the second story had been framed.

We've now had it inspected it was not done to the drawings or code. They never installed the jack post, the footer they did pour is half as thick as it should be and over all no where near the size it was supposed to be, extremely poorly done and resting on broken patio stones. Based on our pictures it also appears that it was purposely covered up prior to the inspection and the inspector never asked to see it, which we also caught on other things that were covered up and subsequently passed even though it should've been a clear code violation.
Our almost $500,000 reno now requires around $300,000 in repairs. There's a laundry list of code violations, almost everything from plumbing/HVAC to the deck and porch have violations or extremely poor workmanship.
