Paul Mon said:I was able to remove the pole by adding another support beam. The existing poles in my basement were about 9' apart. The existing beam was a 5" x 8' (18) meaning it weighed 18 lb./foot. The new beam was 5" x 8" (21), it deflected much less than the original. I used a jack to slowly raise the new beam into place. The new beam is about 18' long and was supported at each end with poles that shared the footer with existing poles. I did not break through the slab and set the new poles directly on the existing footer. They are sitting right on the slab. I did drill and pin them in place, but don't believe that this is really necessary. Before starting any work I measured and cut a 2 x 4 to the exact height between the floor and the existing beam, in the spot where the pole was to be removed. My intention was to make sure that the existing beam did not change location (vertically) when the job was completed. With the new beam in place and the new adjustable poles at each end I slowly cut the middle pole and as the old beam started to slowly drop I would raise the new beam to compensate. Obviously I had a couple guys helping me with this part. One thing that I anticipated was that the new beam would bow due to the increased length between supports. I placed wooden shims (pieces of shingle) between the beam and the floor joists, 1/2" shims in the middle and less thick as they got closer to the support poles.
I got the height of the existing beam within 1/8" of its original location. I was very hesitant to try this put refused to put a pool table in a location that had any obstructions. I had seen this modification done one other time with the same result and that helped my confidence. I had recently remodeled the kitchen, which is right above where the pole was removed. There are no cracks in tile or walls. Additionally, I live in upstate NY and we get our fair share of snow in the winter. The pitch on my roof is fairly flat and snow does accumulate up there. After seven winters there has been no settling or shifting. IMO, the support is probably stronger now than before. When I was all done I boxed in both of the poles and one of them makes a little wall jutting out into the room. This made a little alcove for a sitting area on one side and a place for the dartboard on the other. The hardest part of the entire job was getting the beam through the basement window and into place.
