Hi, I am having an addition put on my house & they have the foundation & crawl space in & then put in 1'4" plywood for the floor, nothing else. This is going to be a small house addition & the floor is already warped before the roof & sides were up. It is getting more unstable & they are putting the walls up now. Am I wrong in thinking the flooring is not correct since it isn't stable. I have repeatedly talked to them about fixing it & they said it will be fixed after the walls are up... WHAT? Do I want walls setting on 1'4" plywood? I'm not happy about this but if it is the right way to do it I'll give them a break. Thank you & I hope I'm in the right forum.

1/4" plywood floor
Do you have a permit? - That would protect you from the construction you getting, which is totally improper, out of line and approaching insanity. It would never be approved when a permit is applied for and not if it ever got to inspection - This is assuming that your description of what you have is 1/4" plywood and nothing else spanning between floor joists.
