I have a 45' x 25' basement that we are finishing and I have a question about the support posts holding up the beam in the middle of the basement. (The house is a one-level ranch.) The beam is 3 2x10's nailed together and there are 3 cinder block columns spaced out over the 45'. They are spread out 10-11' from each other. The one in the middle is in a terrible location for what we are trying to do. What I would like to do is put a jack post on each side of the middle column and then take it out. The two jack posts would be about 8-9 feet apart from each other and they would be even closer than that to the two outside columns. I would then have four support posts but the one in the middle would be gone, which would serve our purpose much better. Is this acceptable to do?
Some concerns I have are:
I believe the column I want to remove is on a footer and the jack posts would just be on the cement floor. Is that an issue?
Does the location of that column matter or is it only the distance between columns that matter?
Thanks in advance for your help!
