Went from a dirt pad to this in two and a half days...with setbacks. These guys were quick and did a pretty good job of cleaning up their mess. We decided to leave a panel off for the cement pour instead of pushing cement the full length of the building. I may have them take another panel off near the door so I don't have to use a pump truck.
Rollup door and walk-in door hardware will be installed after concrete is poured. As of right now I would definitely use them again. A friend of mine built a 30 x 50 and his looks great too.
