I have a parallam PSL in my unfinished basement and am wanting to move the support pillars for finishing purposes. The parallam is currently supported at the end by wood posts and 2 steel pillars in the center (7.5' in from the end with a 9' gap in the center). Can I add another pillar and shift them around to create a 9' gap from one end to the first steel pillar, and the other 2 pillars at closer distances? I can't find documentation on the product and don't know how to calculate loading
Edit: Looking at the basement structural plans, there is a long footing run underneath where the poles are and where i plan to move them. I've spoken to the engineer who designed the basement and said as long as the pole is on that run of footing, I should be fine. The long footing was poured because it's a load bearing run and poles were there to give me an option of either a load bearing stud wall OR just the poles. I even have pictures of the footing pour prior to basement floor pour to confirm it exists.
