I don't see a need for an engineer, i tend to think it is common sense, here you can see schematic, before and after for the post areas. On the left is how it is now, and on the right as i plan to do.
The posts in the basement have worked well and are very solid. As it now i just remove 1.5 TONS of old wood subfloor from up there, yes holy crap all by myself.
I'm just guessing about the second wall, it is probably not as many studs there as i imagine. The thing is, the 2nd wall is not sitting on anything, i guess i will install another joist 3" . I guess at the time 2 posts seemed okay, presumable the structure further up toward the room is sound. I don't really want to open that dry wall up of the ceiling.... sign/
