$10,000!! Wow. I do not think you have a enough housemovers in your area to compete with each other. I talked with my nephew just a few minutes ago. I described the situation...28' x 48' pole building one wire to be raised and 400 foot move.... he said ballpark $4,500 or so. If it were some distance, it would $5,000 on up. He typically charges $9,500 as base price for house, depending on size, distance, etc. House is a lot more work than your pole barn would be.
I had a Wicks pole barn built three years ago 40'x72' with 40x32' 6" concrete slab in shop part. Insultation throughout ceiling and wall insulation in the shop part, 15' side walls; 15 high by 12' front door with opener; 12 x12 back door, two man doors, two set of windows, cupula, transluscent panel around upper south side, etc. Come in right at $40,000. I figure another $10,000 to get right lights, heat, and water in it; still working on some of that.
If you could get build a 28' x 48' in this area for mid $20,000 with the slab you have you would be doing well.
My nephew is probably biased since he moves them, but he said by taking it apart, it is hard to ever match the holes back up. I suppose it can be done but you better number and mark everything very well, do lots of measurements, and take lots of pictures. And, if you are hiring it done, you probably end up paying the construction price (which is what it is to put it back together) plus the tear down price, which would take less time and care, but not a lot as you have to take time to number and label pieces. Deciding to disassemble and reassemble it is a judgment call; but unless there is something I have not seen, thoe who told you it had to be disassembled and reassembled are just wrong. If the tool you have is a hammer, then every solution is somehow going to involve a hammer.
Here, you could have a pretty nice building for $750 for the building, $7,500 for the slab and foundation, and $4,500 for the mover. That is $12,750, which is probably a half price building or less compared with building a new one and putting in a slab. Sounds like the housemovers have plenty to do and/or want to get a large chunk of your savings. It is definiately not a hard move with the right equipment. One day to get to the site and set up; maybe pick it up; second day to move it and set it down and pick up stuff and head to the next job site.
The last pole building I helped my nephew with was a 30 x 60 and moved it about 6 miles.
By the way, I am several states away so from Indiana so not drumming up business for my nephew. But he has been doing it more than 25 years; his dad before that, and his grandad before that...and his uncle and cousin also move houses. And they all make good livings at it.
Well, too bad about the price. All the recommendations about plenty of bracing are good. Backing in a semi flatbed trailer and then setting beams across it to connect to beams on the side wall will work. You do not real heavy beams but it will be trick to move them in and out with a skidloader. Make sure you know where the center is to balance them. I would like to sugget something about something different regarding jacks and cribbing but it would beyond what I have seen done. My nephew uses hydraulic jacks and plenty of 6"x6" and 4"x4" cribbing to create a solid base for the jacks.
You could spend a few thousand on lumber and rentals and still be well ahead of the game. Kind of all depends on how you look at it. Your $750 building is far from a $750 building, but you could spend the money on lumber and rental of the right equipment and still have a good building for half the price of a new one. I love my building. Hope it all goes and well and let us knoa.
