I'm no architect but those bones don't look like no building ... No seriously, the pillings, the excavation, the trusses etc are all wrong for a multi story commercial building. I also do not see any primary columns and when you build a building you usually put all four sides up at the same time not two and leave the other two open.
Of course I am by no means sure lol. just an amatuer's perspective.
Assembly plants are commonly built this way.
