Please...help with sinking barn

[arkydog]

My barn is sinking - more rear than front. All uprights either have termites or are rotted. Some uprights are 4 x 4, some 2 - 2x6's. I know how to jack-up barn and support between rafters, but since barn needs to come up between 8 - 14" all the way around and can't jack all up at once, 1 - 2" at a time to let barn settle. Plan to support each one at a time and cut off old post and dig out with backhoe and replace with new. I know how to support while replacing each post. Just can't come up with way to make uprights adjustable to raise each upright 1 - 2 " at a time to level and let barn settle.
Attached is picture of barn below grade.

what we did with my father's barn, was to cut out 8-10' (about 4' high) at a time, pour a 4 foot frostwall with concreat. then frame the wall back up from the cement. if you did this, but scabbed new poles along the sides of the remaing poles, but use screws or lagbolts, then you could unattach a section, raise it a couple inches, then re fasten it. and when you get done, with a cement foundation, you'l never have to worry about it again /forums/images/graemlins/laugh.gif

I's suggest than you slot the center of the posts and then sandwich it between two other pieces of timber that are drilled with a bolt through them with nuts and washers. You can then place a long bolt through as you raise the posts in small increments, alternately loosening and tightening the nuts to clamp the remaining post.

The first time you jack the post, you should cut it to sound wood and place blocking under it after it is jacked and the nut is retightened.

You can also just drill a new bolt hole each time also instead of the slot.

When you are a the final heightyou place full length timbers on the remaining two sides of existing post to pick up the load.

The one item that needs to be in place is a concrete footing around and below the existing.

Thats a great suggestion. Since most of the post are 4 x 4's, do you think that when I get the barn leveled, I can just put another 4 x 4 in between the top and bottom ones, like three piece sandwiched inbetween two 2 x 4 bolted, that would work? The 4 x 4's would carry the weight and the 2 x 4's woud prevent side movement.
Also while I am doing the outside post and having to remove the siding, should I remove the siding on the other side so a wind gust wont cause pressure build up and cause the barn to collapse?

Thanks
