Sub Floor Warped- Raised House under construction


Before the roof had been felted we experienced heavy rain for a number of days. The first sub floor of my raised house has warped badly. The first floor is about 2000 sq. feet. We were planning on installing real wood floors which need to be nailed down to the subfloor. What can be done to correct the warped subfloor?
The headers and exterior doors are already in place. The contractor is looking into using patch over the low areas and then coming back with 1/2 inch plywood,but he is not sure that we will be able to do that because of the door headers and doors that have been ordered.
In time will the plywood dry out and become un warped?
Could the plywood subfloor be sanded down so that it's level?
Can all of the plywood subfloor that will have wood floors be replaced?
Help

They will dry out, but they will not,"unwarp". Whether you can fix the floors depends on the extent of the damage. A small amount of warpage can be sanded out.
I have no idea what, " using patch over the low areas and then coming back with 1/2 inch plywood" means, but it sounds like a half-assed solution from someone who wants to limit his liability.
Take some pictures.

This guy can't be a contractor to say that. He has no idea what he's talking about.

No.! The simple solution is that he replaces it. This is something that is done every day. It takes time but that's the only way to fix it.
