repairing water damaged sheetrock

Hey all,
I just found this app and its at the same time amazing and intimidating. You think you know so much but there is always another way or at least another idea.
Which leads me to my question.
I am contracted to repair two emergancy staircases in a 9 story building that where damaged by a frozen pipe exploding on the roof. The sheet rock is flaking of and was moist in some areas and has since dried. Do I need to replace the rock or can I scrape, tape and prime with maybe a killz type primer?

By the time you go around, find, dig out, scrape, patch, etc, you could have replaced it all taped textured like normal and it will turn out better.

How much you talking?
Mold can appear at anytime when there is no ventilation. I think you just got to dig into it and see how bad it is.

Sheetrock can get wet and be fine. How do you think you get it to curve for radius walls and ceilings? You hose it down till it is soaking wet. But if it stays wet with no ventilation then it can go bad and mold develop.

Mud on the other hand can get wet and sometimes it will turn to a powder on the wall. You can scrape the surface but it might not take another coat of mud or paint. So you need to scrape/sand the compound down to paper.
