Pole barn question -posts on concrete

I've been building post framed buildings for quite a while and have been fairly successful so far. Im currently building a 24x42 and am having trouble figuring out how to proceed. The guy im working for hired out the concrete work himself, and the guy he hired (idiot) insisted on pouring before i had the building done. So we set our posts, put gurts and headers on, kicked off the outside of the building all the way around and let him go ahead. I do this quite often, HOWEVER, i usually include the concrete work in my bid and sub it to a friend of mine who is careful, does good work, and most importantly communicates with me. Well long story short, mr. Idiot hit multiple posts with a skidloader (all on the same wall), didnt replumb them, didnt talk to me or the homeowner, and poured concrete around them. The only three options i can think of is to #1. try and pull them back with a come along. I highly doubt this is going to work because theyre over a foot out of plumb and thatll never look right, plus i dont like the added stress on the wall itself and the purlins on the roof. #2. Cut holes in the floor and start from scratch. The first reason this isn't going to work is the posts are 42 inches down in gravel and have lift guards on them. Ive had to pull posts with a forklift before and it wasnt pretty, and was without new concrete to worry about damaging. I also worry about compromising the strength of the concrete by loosening the fill under the concrete and not being able to get enough fill to stay in where i had to dig it out. And lastly, im absolutely sure the guys not going to want me to cut holes in his brand new floor. #3. Cut the posts off with a chainsaw, attach them to the concrete with brackets, replumb them and call it good. I dont like this idea a bit either, but im not sure what else i can do.

Opinions?

Its a father/son operation. Ive never met the father but the son has no business running jobs. He showed up when we were setting posts and started asking me how far off the grade was and how much fill it was going to take him. Im like uh you do concrete work why are you asking me? I kinda doubt the dimwit even realized he moved the posts or that it was a serious issue.

Thanks for the reply.

What about cutting the posts out on that wall (its a gable end, so its narrower), 2x6 16" on center framing that one wall from corner post to corner post with a double top plate and setting the truss on top of it and attaching it to the corner posts with ring shanks and the wall with truss clips? Feasible? Im really not trying to gouge the customer because its not his fault, but im insisting that its done correctly. And it doesnt help that all i hear from the guy is hurry up!

Your customer is the idiot.

How is it not his fault? Didn't you say he hired his concrete guy?

Make certain you point out what is wrong.

Give him a quote to cut concrete, pull posts & do it right.

Tell him to give you a call when he figures out who is going to pay for it.

If the concrete was cut out, do you think you could pull the current posts straight? Maybe use water to saturate the soil for further help? Then pour concrete back in place.

Document everything with photos. A digital level held to the post would be a great photo, although a shot down the wall sounds like it will be revealing.

Why did he not go with your concrete guy? Also, why did you give him the option?

A complete one number bid would not have given him the option. No way would I have allowed a new concrete guy to work around my building, and if I had to, I would have been there the whole time. Money for me to stand there and watch would be in my end of the bid.

Sounds like a huge mess. Pulling the posts a foot back into place will disturb the compacting under them. It will be hard if even possible to know if they are solid.

They must have hit them pretty hard to knock them a foot out of plumb. I'm not a pole barn guy, but wouldn't a solid compaction or concrete around them keep them from moving in the first place?

He didnt go with my concrete guy because the idiot he hired did the floor for less money (ironic, huh?). I dont blame the customer because while he IS a complete fool and doesn't know squat about construction, i dont feel that he should have to baby sit so called "professional" contractors. Ive made it very clear to him that its not my doing. He understands that. And yes, i think i could plumb the existing posts if there wasnt concrete around them but so far hes been dead set against cutting the floor. I told him that was the only option i was really comfortable with and we could either proceed or ge could pay me for the work ive done and take his chances with someone else. I HATE walking away from a job but i cant be responsible for a sinking building or pad. Well see what he says!

Vinyl hanger - theyre really not hard to move at all. The footings are filled with gravel as opposed to concrete, which is code in most places, the gravel allows water to drain away from the post. A pole barn gets stronger and stronger the further along it is. In this case there were no trusses on the building. And when i say a foot out of plumb i mean a foot out at the top. Since these are the posts on the gable end, theyre significantly longer than the posts on the sidewall. A 20 foot post doesnt have to move as much as you might think to wind up a long ways out of plumb.

I know that the posts will move shockingly easily if the roof isn't on. I worked on a pole barn years ago and a couple of the guys ran the jumping Jacks too close to the poles. Pushed em out of line.
A bit of pushing and using the jumping jack on the other side and we got them back plumb.

But you prolly didn't have someone come behind you and pour the Crete floor after they pushed them out of plumb. This sucks that this happened but I think you are on the right path. Tell the owner the options and get in writing who pays for the repair. Go no further until a change order is signed.

Besides the other questions, there's a structural issue involved. Attaching posts to the slab isn't going to give the resistance to deflection that buried posts have. I also doubt that the slab was designed to take the point loads you'll get if you attach the poles direct to the slab. That pretty much leaves cutting the posts off, and putting a heavy sill on before rebuilding the wall.

My 2 cents, cut the concrete, to make it look as nice as possible I would cut a strip all the way down instead of just cutting a large area around each post. Then it will more likely blend in with the rest of the floor as a contraction or expansion joint.

Secondly now you know not to let some clown on your jobsite. We've all screwed up like this before. In the end this will cost you time and money, at least time anyways. The homeowner should talk to the concrete guy and ask him to pay for it. The concrete guy should come it and take up a strip of the old concrete, pay you to fix the posts and then they can pour new concrete. Hopefully it works out like that.

I don't build new structures like this, so forgive me if I'm wasting time, but I was thinking: is there any reason you can't cut the damaged/out-of-whack posts off flush with the concrete, then install new ones immediately adjacent to the concrete pad?

Then if your new bottom plate has to sit on concrete, could you pour an extension onto the end of the pad, around your new posts? Obviously who is paying for this would have to be worked out ahead of time.

Or am I missing something that would be obvious, if I built pole barns?

Could, yes, and that might be what we do. However, that will entail needing prolly $500 in extra materials and having a little tiny strip of concrete on the back thats seperate from the main floor, and in my opinion will come away from the rest sooner than later. The whole thing just stinks.
