Water damage to newly framed house.

[Geemoney]

I am watching the construction of my first house.
During the month of June we recieved 10 inches of rain.
All the framing was done including the 2nd floor before the rain came.
The house sat with 2" of water on the upper floors saturating the chip board and dripping down onto the main floor.
I understand the the framing can withstand some water without damage, but what about the flooring?
It has dried out some over the last week but it seems spongy/soft with some chips coming up.
Will the builder replace this, or should I pass on this house?
Is it going to be a structural or mold nightmare?

Sorry for the many questions.

Chipboard or OSB? I would be very leary if it was chipboard.. not quite as leary with OSB.
No matter what it is - if it's feeling spongy I would talk to the builder about replacing it. Otherwise I would pass on it.

Sorry, I am a newbie, it would be OSB.
How big of a deal is it to replace the whole floor now that the roof is up?
Would they just cut arround the upper floor framework and place in new sheets?
Is that going to be a decnet dream house afterwards or is this going to be a nightmare on my street?

Thanks for the help

It's not the best situation but you can use a flush cut saw and run along the framing then butt up to it. Like I said - definately the best situation.. you would probably have to add blocking to hold some ends up.

OSB will swell when it absorbs water, which could lead to it feeling spongy. I'm told that this isn't really a problem. I'm not sure. I personally don't like to use OSB, and spec'd everthing in my house that's under construction with plywood.

Of course, we've seen an enormous amount of rain too, and I'm starting to worry aobut some of the plywood delaminating. But at least that's a clear failure, where with OSB you really can't tell by looking at it.

If the product is an AdvanTech OSB I would not be too concerned with it being compromised by standing water. This stuff is pretty amazing when it comes to surviving water saturation. Check with your material supplier for the product type used.
