A few weeks ago I brought in a general contractor for some initial consultation on what it would take for me to move two load bearing walls out of my way. The Basement is new construction, but there are several framed walls that are already in place sitting on underground footer beneath the floor and are helping to hold the house up. This includes two walls that are in the space where the studio will be.
After providing a materials list he recommended a local lumber supply company that has these items on hand and could deliver them right away. I called and the company was great. After doing some quick price checking with a couple local big box suppliers, I called the recommended supplier back and placed an order for (2) 11 7/8" x 20' LVL beams and (2) 9 1/2" x 10' LVL beams.
The beams run directly under the ceiling joists taking the place of the load bearing wall and will rest on a few columns of (3) 2x4 studs (trimmers) grouped together on each end of the beam. The beams take all the same weight of the load bearing wall, distributing the weight across the entire beam system and transferring the load down the trimmer columns on each end down to and then through the floor to the 1' thick by 2' deep concrete footings underneath the 3" concrete floor. The footings at this part of the basement are perpendicular to the ceiling joists. This means the beam will have to drop down and sit underneath the joists giving me a 12" x 3.5" beam running across the studio overhead that I will need to creatively conceal.
If the footings were running parallel with the wall I could have set the beams up into the joists and hidden the beams. Unfortunately, not the case here. But a beam dropping down a little is much better than having a wall right in my mix position.
They’re here!
The LVL beams arrived. I feel like I should have a ground breaking ceremony or a mini celebration of some sort to mark the first of many building materials to arrive. Well, enough of that. Now back to work.
Next step
I’ve been researching the best 2x4 studs to use and what length to use etc and now I’m ready to buy the studs, start building some walls (possibly in 3 days), and put up some additional temporary joist supports so I can safely cut out the load bearing wall and put the beams in place.
