A guy has asked for me to level his shed. The building is 14' x 24'. Nearly one half of it (14' x 10') has sunk about 8 inches. The building is 24 years old and suffers from extreme dry rot on the outside/bottom lumber, but all of the joists appear fine.The end that has sunk is setting on dirt. The original skids have deteriorated completely. The ground stays very moist or wet all year.
About 8 years the sinking began due to the city digging and installing a waterway/mote 4' past the end that has done the sinking.
I am thinking about running temporary rafters/joists about 10' long, longwise from halfway to the end that has sunk the most. Running a temporary beam (20') sideways in mid air, under those, and securing, and lifting using car floor jacks. When it's level and at the proper height, digging and pouring a retaining wall our of concrete at the end, and running new skids under the length of it and setting their ends on the new retaining wall.
What weight? I see no mention of any weights. You do have a guesstimate of the entire load you intend to lift?
How do you intend stopping the car jacks from sinking into the waterlogged ground?
Had a friend who used to take on jobs, which had usually been turned down by other handymen for being too problematic (sometimes if I had a day off I'd help out but was never an expert in DIY etc), quite often something would go wrong, but he'd always stress beforehand; that there was absolutely no guarantee of success. Sometimes it worked out OK, other times not.
Are you desperate for cash, or does he have a stunningly attractive daughter, who you wish to impress?
