In an upcoming project, I need to hoist a 10’x 9’ 2×4 16’ OC sheathed wall up three stories, about 30’. The addition the wall belongs to is rather small, just 5’x10’, so I can’t think of a way to frame the wall on the floor deck. I realize I can hire a crane & operator, and will do so if I have to, but I’d really prefer not to.
You can see what is going on in the picture below. That left upper window will eventually be a doorway leading into the addition. The wall in question on the left, immediately adjacent the neighbor. I’d like to frame and sheathe the wall on the ground hoist it straight up and then have the ability to rotate the hoist, crane, jib, whatever, to place the wall where it belongs.
I am open to any and all solutions at this point. I have resigned myself to hoisting it up, but there’s a flat roof above the space that perhaps I could use, or maybe someone can figure out to frame it on the deck, not sure. I need to get as much of the wall done before it is in place to limit the amount of time I will have to access my neighbor’s property.
Thanks!

How to hoist wall 30'
Not to over simpllfy, but why not but build the larger wall in two halves. That would make all of the sections about the same other that the sheathing. Obviously, I know only what you have written and described . The larger wall may full of windows or what ever making that impractical . I don't know. Just a thought.
Thanks for the suggestion. My goal is to actually side the wall before I raise it, so while this is an awesome idea, it won't get me all the way where I want to be.
IMO it seems like this is a lot of trouble to go through for such a small wall. But if you are resigned to sheathe and side on the ground a crane is your bet bet. What type of siding are you putting on this addition?
What I would do is not frame and sheath on deck, instead I would set my bottom plate, corners and top plate in place, brace it plumb, then go back and fill the rest of the wall with studs 16" oc. Its a technique I use normally in situations where a foundation is badly out of level, but it could be used in this circumstance.
You would still have to sheathe with the wall standing, but your only installing about 12 sheets and 3sq siding.
The only other option that pops in my mind would be a scissor lift, and sliding it off the lift. $500/week around here, 500lbs capacity would carry the wall but the siding would be pushing it.
This is intriguing, but I am not sure what you mean by frame and sheath vertically. Do you mean standing up, as opposed to on the deck? I have thought about this, but had some concerns... would appreciate your thoughts.
1) How do you account for the sheathing that extends below the bottom of the wall to overlap the rim joist? I cannot figure out how to make this work.
2) Somehow I envision the wall falling off the side as I attempt to rotate the wall into place. Any thoughts on how to pull this off without destroying the wall or hurting anyone?
Thanks!
Yeah, the bottom intersection would be a problem -- have to handle somehow. This is maybe where the bos'n's chair would figure in. I can imagine having a section of trim that could somehow be fastened in place from the inside, after the wall was rotated.
As to keeping it from falling, it seems like you should be able to brace/tether it so that it couldn't fall outward, though it might require, eg, placing some eye bolts in the existing structure. Probably the bigger trick is figuring out a "bearing" to use during the rotation, to carry the weight.
