Well I guess this means I've been a real slacker.
Confirmed when this popped up on my FB memories.

Quonset building 40' x 56' 16' center with end walls
We are the third owners, it has never been erected.
Was a heck of a load, 8900 lbs.
Takes 6000+ bolts to put together!

Time to get it in gear.
A late spring ice storm caused some unexpected tree removal near the building site.

May of 2020 I purchased the adjoining property to the west of our current workshop.
It had a nice raised garden spot in-between the two properties. Decided this was the spot for the Quonset.
Leveling out the garden spot with our skid steer and adding a culvert to an existing one.

The building did not come with base plate connectors.
Instead building was to be anchored using a trough foundation.

After much research we decided to purchase base plate connectors to ease building erection.

The bottom 54 panels then had to be drilled to match the base plate connectors.

The buildings panels/arches had sat outside stacked for who knows how many years.
We've had some pretty decent fall weather so we pressure washed both sides of the 216 panels/arches.

My normal concrete guys said they were more than six months out.
Had come to think it would now be spring before we'd see any concrete work.

Ran across a local builder and he recommend a concrete guy I knew of but had forgot about.
Contacted him for a quote and date. Quote came back for nearly same money as our usual guy but this guy could get to it within a couple weeks.
I said get us on your schedule. He showed up when he said and got it knocked out.

Slab (with footers 16" x 16") 41'-1" x 56'-0 1/2"

Gonna give the concrete a month to cure and then hope for decent weather to get started with erection.

FB market place score should aid in the erection of the Quonset building.

5 sections with cross braces, 3 aluminum planks and some leveling tube inserts.

All for $200

Mentioned to the seller when picking up, I was looking for a set of scaffold wheels.
He thought the had a set but could not locate them while I was there.
Messaged the next day, he had located them, said swing back by and they were mine.

Good choice on the base plate mounting. I did the trough method. Forming for the trough was more time consuming (and materials) and then when the building was up, I had to fill in the trough on both sides of the building and then use angel brackets to the foundation bolts. If I had to do it again, I'd buy the base plates. US Steel does make an insulation kit that I wish I had bought. Once the building gets full of stuff, it's not so easy to go back and insulate it. Great deal on that scaffolding.

How wide was your building? Any tips on erecting it?
My builders manual recommends half arch for anything over 35' width.

My plan is to attempt full 40' wide arches. Going to build a 20' long wood jig/cradle and try to lift into place with skid steer.

My building is 20' wide by 30' long. We put it up one complete arch at a time. . .much easier than 40' wide. Your building is probably around 25' tall. Each arch was wobbley as it went up. . .yours will be even more so. I like the half at a time idea. Once you get the first two arches up, it shouldn't be too bad with all of your scaffolding.
 
Maybe put some framing up to support the wood jig you have at both ends, Move it along as you go?
 
Minor progress worked in during some nice weather days.
Building did not come with the base plate option. After research I thought this was the best way to go to help easy installation of the arches.

Sidewall wall base plates placed for trial fitment.
This was after running string lines to establish marking points to snap chalk lines.

Then it was time to drill and set (110) 1/2"x6" anchor bolts.
My new cordless Dewalt hammer drill with a Bosch bit made easy work of the drilling.

Wiped down the bottoms, ends of base plates and the concrete.
Applied a couple beads of butyl caulking with the cordless Dewalt caulking gun to bottom of base plates.

Each lap has a splice plate that was caulked and bolted down.

Will you insulate the inside. Farmer up the road has a 'shed loves the space but not how it sweats during certain times of the year. If it was a equipment repair/shop, he would be looking into a fix I imagine.
 
Not much progress. Did purchase some lumber and built a lifting jig/cradle (for reference it's 20' long).
Other lumber will be used to support arches as they are erected.
Wanted to do a test lift on an assembled arch but the weather did not cooperate.

Trying to get things a little back towards normal after dad's passing.
Keeping busy seems to help.
Got a crew together last weekend and got after it. Didn’t go as smooth as we’d hoped.
Getting a fully assembled arch up was the easy part, getting them bolted to each other proved to be quite the challenge.
We got 3 up the Saturday and only 2 Sunday. They say after 4 or 5 are up it gets easier, hope that's case!

Looking good. That is going to be really nice. Glad mine was only 20 feet wide and about 12 feet tall in the middle.
