Using a 16' LVL beam to replace a section of load bearing wall. Single story house, roof load only. Basement is cinder block with 3x12 center floor support and 2x10 at 16 inches to support the floor. Jack posts every 6 feet support the center support.
My main question deals with the fact is that the wall is actually about 1.5 feet off the center floor support. So the actual posts/framing (doubled or tripled 2x4's) that the beam will sit on will end sitting on top of an existing 2x4 footer right over the floor joists.
Is this close enough to the center support to not worry about it?
If the end of the footer where the post support will sit on is in-between the 16" floor supports (make sense?) Should I double up a couple more 2x10s and put them under where the most load will be?
Any need for additional jack posts anywhere?
Second question, I've seen people say you can build the 2 temp support walls directly under the ceiling drywall and other say you need to cut the drywall and get them under the actual joists- What is the consensus? the total roof span of both rooms combined is about 30 feet. There's blown insulation in the attic and it's all gonna come raining down!!
