Well, not completely, but I was handing bags of salt to my Dad and all of a sudden he says "HOLY S$&#!, come down here!" We've put a floor joist in there but still aren't sure how to reconstruct the whole thing. The concrete is probably 100 years old or so. Luckily the basement only covers a very small portion of the house, it was dug after the house was built but they put the concrete up for support. The last pics of the floor sagging were taken after Dad cranked the joist up about 2 inches. When he started I could see through to him in the basement. The pole you see in the first few pics is not the new joist, it's an old support pole from when we remodeled about 5 years ago.
