I built my shop in 2019 when we moved from Calif to Texas. It is a metal pole barn. 25' x 60'. I have been perfecting this design in 3 houses, this being the final design that should get me to Trembling Hills. I think the shell cost $30,000, cement floor and apron $15,000, 2019 dollars. I had it foam spray insulated and a small window AC/Heat unit keeps it comfortable. I drywalled the walls, built plywood cabinets, doors on top, drawers on bottom. Cheapie fluorescent 4' lights all over the ceiling. 220 amp service. Shop is divided into 4 sections. 1) Far end is welding/metal working area. Has an overhead I-beam trolly chain hoist. 3 220V welding plugs. 2) middle is 2-post car hoist. 3) other end is wood shop. Next is a wall dividing the first 3 sections from 4) a full feature paint booth. Has inlet dust filters, 40" exhaust fan, ceiling and wall fluorescent lights. My previous rendition had a drain in the floor so it could be washed before painting, after color sanding, etc. Couldn't fit the drain on current property. 6HP 2-stage air compressor in corner of this room, in its own isolated room. Air delivered all over shop via 1/2" copper pipe. Home made cyclone dust collector. Here is the previous version floor plan. It had a bathroom and floor drain. Couldn't get water or drain to my current shop so no bath and no floor drain. Only 60' long, not 64'. Left pop out holds exhaust fan right pop out accommodates sliding 10" miter saw. Coffered ceiling accepts cars over hoist. Walls and ceiling foam sprayed insulation. 15' concrete apron in front of doors. Pole barn construction details. Insulation, cabinetry and drywall. I built half a dozen of these. Really helpful keeping hoses organized. Paint boot in action! Wiring schedule. Material list and pricing for drywalling & cabinets.
A “spread it out approach “ is have the slab poured in sections. I did this before. It will leave a groove between the slabs, I filled my groove with a mix of fence post concrete, easy enough for me to skreet? Off, make it flat. Wasn’t a perfect seal, the FP concrete left slight visible lines after it cured, but posed no issues with dolly’s or things on castors.
I'm another one for the spread it out method. I mixed/poured the floor on both my shop additions and the apron in front of my shop. With a little math I figured a 6'x12' area at 3 to 4" thick equaled one cubic yard. Back when I did my concrete work, a full skid of 80lb concrete bags at Lowes amounted to one cubic yard of poured concrete. I got to the point I could mix and pour one skid of 80lb bags in 2 to 3 hours by myself. But as Toby said, "I'm not as good as I once was". I would probably have to go down to 60lb bags now and a helper. Maybe two helpers. ras
