Can a structural engineer review this beam plan? Are the top-right downslabs really necessary, or could the main beam be extended instead?
I'm building a G+2 house and would appreciate a second opinion on this beam plan.
My main question is about the top-right corner of the drawing (highlighted by the multiple narrow downslab sections along the right exterior wall).
I'm wondering:
- Are these downslabs structurally necessary?
- Could the main beam (SB2) be pushed all the way to the exterior wall instead, eliminating some or all of these downslabs?
- Would extending the beam be a better structural solution, or is there a reason the engineer may have chosen this design?
