Here's my solution for the Alternate using the NCARB program.
I located the Clerestory Window on the south wall of the Cafeteria.
A couple of questions:
1. I added a set of columns and beams at the middle of the Waiting Room space. because without this the Joist span would have been 30'-4" (slightly above the forum recommended 30' max). Is this appropriate? I wasn't sure if it was worse to extend the Joist span by 4" or to use more Columns/Beams. I figured the latter would be safer.
2. Is a beam required at the Window Wall on the Lower Level framing plan?
thanks in advance for any thoughts.
