I've been waiting for this day for a long time. The crew is finally here building my pole barn. I originally was going with 30 by 40 but ended up making it 36 by 48 by 12.
The building is going to be all steel with two 10 by 10 doors. No more ROPS vs header "incidents." On the west side I did 2 personnel doors with 3 windows in between. There is one door near the front and one near the back. I also put 3 little square windows up high on the east side to bring in some light.
For heat, my GC is running a line off our Geothermal system. That line will run into the concrete slap. I'm not sure yet what I'll do for insulation. I heard spray foam is the way to go but it's pricey. Here are some pics so far.
