Floor Joists question

I've been searching through the posts, and haven't found exactly the info I'm looking for, so maybe someone can help.

We are going to have our 1895 3 story victorian home lifted this year and have a new foundation/full basement put underneath. We currently only have about 1/3 basement, with the rest being about 1/2 crawlspace and the remainder not even "crawlable". Basically, the floor joists sit inches above the dirt underneath.

We do know that we will have some joists that need additional support. From above I've been able to get to a few of them and I know they're a bit "spongy".

So, is it possible to just sister new joists to the existing ones? How difficult of a job is this normally? Would it be a lot easier to do this before we set the house back down on the new foundation? I am fairly handy with framing, etc., but haven't ever done any work on floor joists.

Thanks in advance.

If the studs in there now are the least bit soft, replace them. With the house jacked up, replacing the floor joists is relatively easy. You just need the correct tools. You just cut out the old joist and put in a brand new one.
This would be my recommadation. Good Luck

Is it possible to replace the floor joists without pulling up the floor? Our floors are in very good shape.

Yes it is. Just use a sawsall with a metal blade and just run it along the top of the floor joist. This will cut your nails and screws and separate your sub floor and flooring from the floor joist.
