Hello
Expert:  StructuralEng replied 4 months ago.
I can help
Expert:  StructuralEng replied 4 months ago.
I can size one beam as this question. Each should really be asked separately. Is that reasonable?

I can also submit a premium service offer to size all three here

I will have some additional questions
Expert:  StructuralEng replied 4 months ago.
Will each support the second floor only?What is the joist length on each side of each beam?Will any of them support ceramic tile?
Customer: replied 3 months ago.
Are the beams proposed sufficient when the joists at 16" centers they support are 12' in length or less? Yes ceramic tile is supported in the 12'-6" LVL. The other two are existing structure bearing wall open to dimensions given.
