Size of Beam
My contractor is putting in a 6x12 Douglas Fir Beam #1 S4S to replace the load bearing wall between my kitchen and family room. He has got several opinions and this size was the biggest quoted to him. The span between the two posts is going to 15 feet.
I want to know if this is sufficient. The IBC Span tables don't provide the span supported by a 6x12 header. I have attached a floorplan with this post.
I know I should get a structural engineer to look at it but no one is available till 2 weeks in my area and we have so much other work to do and it is all held up because of this wall work.
Please help !
