Can anyone tell me the methods commonly used to jack or support a gable end wall to replace a section of foundation beneath? In my case, the joists run parallel to gable end so makes a non-load bearing (trusses above). I would be replacing about 10 feet of foundation and connecting to the exisitng portions that are still ok. The house is 30 feet wide with floor joists resting on a mid-span beam running the length of house. So there will be a beam pocket support issue too where the intreset the gable end. If it make any difference, the foundation on gable end is a step foundation along a slope.
Thanks.

If you are building a pony wall under the floor joists, then you can install a temporary beam (or maybe two) under the joists, perpendicular to them and sticking out from under the house into the yard. Support both ends of the beam(s), and then remove and replace the existing foundation. When framing the pony wall, stud up to the beam on both sides and then pull the beam out.
If you are pouring concrete right up to the bottom of the joists (i.e joists directly on mudsill), then you can do the same thing but you need to leave a hole in the concrete for the beam and infill after removing it.
No matter what you do, you need to support the last joists(s) under the gable wall, so you're going to have to get something in there. A 10' chunk of 6x14 would be my choice, and let it stick into the yard a ways so that you have room to work. Get some good screw jacks to support the beam, so that you can lower it easily after you're done.

I'll second that.
