I also have three support posts running the length of my basement. They are 3" posts spaced 7' from each other. This is a 2 story colonial. The posts directly support a 8" steel I-beam with a 3/8" flange. These posts are 7' tall and set on a concrete footer. Can I remove the center post leaving a span of 14'. I asked the building inspector, and his comment was.....Maybe! I guess thats what I get for moving into the hills! Thank you in advance for your help.
