Help getting started

I have 30' x 36' post frame building with a lean to that I want to convert to an auto shop. The previous owners had horse stalls in here so currently my son and I are in the process of removing all of those. We've pulled out all of the stalls, and now we're working on the posts. They were meant to keep the horses from kicking over the walls so they are 4"x6" posts who knows how far into the ground with concrete. So any suggestions on how to get these out would be very much appreciated. So far he and I have been digging around them got one down around 2' and still no sign of the bottom and the post is not moving much.

After we get through the post removal (Keep in mind these are interior posts added, not part of the structure of the building) then it's onto the concrete. I'm trying to decide on what options would be available for drain and water. Drain would just be for washing cars inside, the water is already run to the building but currently turned off to avoid freezing. One of the water lines runs in the middle of the building since it was used to get water to one of the stalls. I'd like to try and move these lines to the walls for obvious reasons.

Then I'm trying to find more info on how to finish the interior, insulating options, etc... I'm new to metal buildings so I'm struggling to figure out what the right insulation would be. So again any help here would be greatly appreciated.

Do you have a cherry picker? Maybe drill a hole through the posts, put a long eye bolt through it with a strap to the cherry picker?

If their present location is not going to interfer with future installations rent a electric jack hammer and break the concrete about 12" down, cut the posts off and pour the slab over them.

I had to deal with the same issue at the barn at my farm. I drilled a hole through them, put a piece of heavy gauge pipe through them, and pulled them out with the loader of my 3010 John Deere. Only took an hour or 2 to pull out 5 posts this way, no digging needed. They were down about 3 feet with concrete.

First thing I would is check your local codes. In the town I live in they do not allow floor drains in a garage. And relocating your water lines might be an issue depending on your climate.
