I'm trying to determine if there is a way to get an adequate header in a limited space. Local structural engineers charge a huge fee for this, so I'm hoping to find a solution without one. I need to create a 6' -1.5" opening supporting a roof and 16' ceiling joists 16" o.c. and a 40 lb. live load in a 12' 2x4 wall. The problem is that there is only 4.5" from bottom of opening to bottom of double top plate. Obviously, wood is inadequate. Is there a steel/wood combo or steel beam that would work in this space? Any feedback is welcome.
