The steel upbeams that used to hold up the west end of our building are in the middle of our expanded worship center and thus they must come out. A much larger (35,000 lbs) crossbeam was laid across the top of the west end of the building and the old crossbeam was welded to it. With the welding complete, the upbeams can be removed--of course it's when you take out the upbeams that you find out how well the cross beams were welded together! Fortunately, the beams came out without any problems.
Here is a video of one of the old upbeams being cut out. Awesome stuff.
