This showed up at my brother's place

My little brother's 35 acres is about a mile from my place up in central MN. We both live down here in the Twin Cities.
I went up with him 2 weeks ago and helped him lay out/ put in stakes for the building.
Power company ran underground service in w/meter/200A panel a week ago.
The builders came on Tuesday and left it looking like this yesterday.
40x48 with a 12x24 lean-to on one side.
The doors hadn't arrived yet so they will be back with them sometime after the concrete floor is in.
Pretty fast!
I'm jealous
He will retire up there in a few years.

Very nice building Ultradog. I know it is common now to pour the concrete after the building is complete but will the concrete cover the air gap from the dirt at ground level to the bottom of the sheet metal?? Will he and you finish the electrical work?? ie. shop lights. Plug ins. Switchs Be sure to tell your brother not to fill it up too fast. Ha Ha. Wingnut

Is it gonna be a barnominium???

Looks very nice!

Sharp looking building. Is it a 'shouse'?

Nice!

Having trouble with this. Is there a foundation or not ?

No, there won't be any living quarters in it.
He will sell out here and build a new house there when he retires.
I didn't understand the slab being poured after the building is built either but a couple of different pole barn builders he got quotes from assured him that is how it is being done here.
Dunno...
You know as much about that as I do now.

Pouring the concrete floor inside the building eliminates any issues with rain while finishing, and helps keep the concrete from drying out in the sun.

That is common on simple pole buildings. The poles are set into the ground rather than anchored to any concrete footings. The slab is poured after the poles frame and sheet metal are in place. Less concrete is required.

Two comments:
1. I had a similar 30x50x12 with a 15' leanto like that but running the full 50' length built in Jan 2005 with 5x5 wooden posts on 10' centers to support the building. After construction i had the slab poured, commonly referred to as a floating slab. In about 2010, the posts started sinking and I had to jack them up and attach brackets so that the slab did the supporting. My soil is Houston Black Clay and the Civil Engineer who did the engineering work on our COOP water system stated in his Report the soil is inappropriate for buildings and roadways. So I hope your brother has better luck.

2. Neighbor just had shop built and he had to wait 3 months for the roll up door to arrive. Builder said that the problem is a wheel, part of the mechanism wasn't coming in from China. He said it was a national problem on roll up doors.

3. Added after thought. Filling Station owner had roll up doors on his service bays. One day one of his got stuck so he was under it yanking on the chain, trying to get it to work. It came crashing down on top of him. He survived but was crippled. So, if i had roll up doors, when operating I would be on guard and not standing beneath when operating.

A pole shed is a pole shed. A floating slab is typically a thickened floor with the building built on top of that thickened floor slab therefore supporting the structure.

Grandpa had a 67 Pontiac Tempest. One day on the way to get the mail at the post office 3 blocks away he stepped on the accelerator instead of the brake pedal while taking the corner and hit the funeral home. He ended up in the hospital and never came home. Id be careful too!

One reason to pour the slab afterward is then it won't get rained on before it's cured! In my part of MN I have never heard of poles sinking, more common for the frost to push them up. When Menards built my dads first shed they put concrete discs in the bottom of the holes to support the poles, but I have never done that. Our garage on the CA border hasn't moved much, but every winter the ground (no CC floor) heaves up enough to push the door up a little, I slotted the locking brackets so they can move.

I have been waiting on a roller for a few mounts, the door is working OK for now.

A bud just had a building installed after they put the doors up one fell its a 12X16 roll up door it just fell. It took several months for them to get another door he could not get a final inspection and power till the door was installed. In a nut shell the building crew did not know what they were doing.

It seams every building I see put up they install it flat on the concrete I tell them water will run under it they think it can be sealed. My bud built a pit to put his motorcycle lift in so it would set flush to the floor water is running in from the side of the building and filling his pit.







Water coming in from the side with the shed attached.




The door in front of the MH that fell I think the door was shut at the time it fell the MH was not in the building when it fell.





BTW he used LED UFO lights and loves them.

Now that I have more views, that looks like a 30x30 a neighbor just had built. The framework is 2x2 12 GA, square, Galvanized tubing. The slab was reinforced like you would have with a home slab...reinforced horizontal beams. The building is attached via bolts that are screwed into holes drilled in the slab...interference fit.

His building leaked also during the first big (windblown) rain. He had the siding running horizontal rather than vertical as he wanted to use the reinforcing bends in the sheating as a support for his flexible sheathed electrical cable. I looked but couldn't tell how much overlap there was for the siding over the edge of the slab. His was built on the side of a hill with gravel packing around the base spaced no closer than 4 give or take below the top of the slab so there was plenty of room for the rain to run off.

The pier holes were drilled, poles installed, and filled with concrete to the surface of the pad. After it was finished, the concrete crew installed 2x6 boards attached to the inside of the poles as framework for the slab and poured 5 of 5 bag concrete over #3 Rebar on 18 centers, on support stands to center the Rebar in the slab. The concrete was up against the boards but was not structurally attached. Therefore the slab could stay on top of the ground floating while the poles and building sank. Once I jacked up the poles and attached the braces it was no longer a floating slab. It was attached to the building.
