I can help.
Will this be supporting a floor only? An attic only? A floor and an attic?
What about attic?
So 3 - 1.75" x 9.25" LVL in addition to the 4 - 2x8?
Are the 2x8s continuous from one end to the other or are there spliced over the posts? Or elsewhere along the length.?
If they are continuous, then you can use 4 - 1.75" x 9.25" 2.0E LVL. Three won't quite work.
No problem. I'm happy to help. Good luck with your project.
