rdln,
There will only be one overhead door at one end, 20' wide by 10' tall. Their will be an entrance door at the other end and 4 windows. Also there will be a continuous ridge vent, 2' overhang with soffits and wainscoting, as well as gutters and downspouts. I didn't ask for all of this but it sounds like a standard package. The posts are laminated PT and set in concrete. The slab will be a 4", 4000# mix with 3/8" rebar on 30" centers, with a 4 mil vapor barrier. It also includes stub ins for plumbing in a 1 BR/1 BA/full kitchen apartment. It also includes Thermax insulation and vapor barrier, as well as stainless screws throughout. The building is evidently 42' wide vice 40', as that is a standard width for Morton, and would cost the same. The rep is going to work up a more detailed quote later this week, because I asked him point blank what I was getting for this price, as it is a lot higher than others.
The Mennonites' barn uses standard 6x6 PT posts, which I'm not that excited about due to warping/twisting, but am willing to take a chance on. I also rechecked, and their standard is a 29 ga steel, with a standard grade of galvalume and paint, not Kynar. I can get that but it will cost more. They also do not do site prep, concrete or plumbing, but know those who do, making me the general on the project, and responsible for coordination. I do like their price and work ethic though, and it's hard to reconcile the price difference between the two. I guess I'll make my decision when I get firm quotes from both parties. If anyone has any opinions or input, I'd appreciate it.
