Well, if you're looking to do this job yourself, unless you're already familiar with foundations, code, house-jacking, pouring, and so on, I wouldn't attempt this yourself. (Just my $.02 ...)
IF, on the other hand, you're going to have it professionally done BUT just want to know how it's done, there are 2 ways you can get some info. 1) Talk to the Pros that estimate the job. I'm SURE they'll tell you how long you'll be out of the house, and why. 2) IF you have any 'specific concerns' as to how the retrofit is done, please ask your specific question.
In short, it depends on how the home is constructed as to how they'll do it. Heck, the Contractor may use concrete piers.
My best to ya and hope this helps.
