My 100+ year old 18X10 wood floor garage, got pulled off to be put on a new slab up in the woods for storage.
Put it on skids made out of trees and draged it with the John Deere 135C.
I did all the ground work my self, screened all the gravel that came out of the hole and still had over 100 yards of gravel brought in.
4ft frost walls 10 inches thich in footings all poured using aluminum forms.
Final shape, pre built trusses on the top 12 inches on center, 5/8 underlayment on the roof.
Final inside height is 18 feet to ceiling in the middle bay, with only one cross beam in the middle.
Spray in foam insulation 8 inches in all walls and 12 inches in all ceilings.
1 12x12 and 2 10x10 insulated over head doors with industrial jackshaft openers. The center door is elevated to gain more height for excavator booms.
