My new shop was just put up and i was impressed enough by the 4 guys doing it that i thought i would pass it on. They contract for Quality Structures out of Haven Kansas. These guys were the hardest working crew i have ever seen. They were from a small amish community here in Kansas and they put this thing up in 2 days. Its 40x42 with 12 foot side walls and two overhead doors. They were shorted the corner trim pieces but other than that the structure is done. Now on to cement, wiring, and insulating.
