If everything goes right, we'll be closing on a house Dec 30th. 5 acres in Franktown. Currently, it has a greenhouse that has electrical and gas. My plan is to build a shop. Could be 30'x40' and use the utilities to the gh.

Does anyone have experience with metal building kits? That area appears to need 40" snow load rating. Most of what I've seen is only rated for 20"

I do a lot myself, so I'd probably grade the area and prepare the concrete area, footers, rebar, mesh. Any insight on the best way to do the concrete? I did our hot tub pad 12'x 16' in 2 days with a mixer 2 bags at a time. Is it worth it to hire trucks and finishers? Looks like $2500 just for the concrete myself vs $6-7k+ to have someone else deal with it.

Thanks
