Seems to be the year for new shops getting built. I started mine a few months ago and thought I would share some pics. It will be 26' x 38' with 12' walls. I started off planning on a foundation / footings build, but the cost was more than double what I had anticipated. Went back to my engineer and had change the design to a monolithic slab with thickened perimeter. He ended up with 24" deep sides that were supposed to be 12" thick. By the time the concrete guys gut done with the excavation, the edges ranged from 24" to 30" and around 18" thick. I was happy with it as I suspect it will survive an earthquake of up to 9.0. I also wanted to do 24" on center for the walls, but was told the 7/16" OSB had to be nailed every 16" to comply with the wind requirements. City requires all buildings to survive 150 mph wind speeds and going 24" on center would have only provided protection up to 142 mph winds. I am told the highest winds ever recorded here are around 110 mph. Oh well.
I am doing in floor radiant heating so in the photos you will see the tubing I installed. After sitting for over 90 days, the lines are still pressurized to 100 psi. I had them at 60, but the inspector required them at 100 before he would pass it. The end of the building with the garage door (10' x 10') will also have a car port for parking trailers, loading in bad weather, etc. The overhang will be an extra 16' with 6" x 6" posts supporting the roof on that end.
