hmmm
Expert:  StructuralEng replied 1 year ago.
ok. I'll look once it's attached. What exactly is this question?
Customer: replied 1 year ago.
This is the foundation plan, roughly..... at the top of the page, the beam is 14' in the air, yet the concrete wall is only 8' tall.

SECTION 2

section 1 is the south end of the building or the top of the plan
Customer: replied 1 year ago.
question is... what do I do about the footing at these points that I have circled on the plan
Customer: replied 1 year ago.
right now I have a continuous footing
Customer: replied 1 year ago.
Do I need to do something different at the 8" wall?
Expert:  StructuralEng replied 1 year ago.
I apologize for the delay. It was almost 1:30 am here and I fell asleep
Expert:  StructuralEng replied 1 year ago.
Something isn't quite making sense. Is the beam sloped or is the top of concrete wall no at the same elevation all the way around? I thought the beam was supporting two floors, but it looks in the section like it's supporting only the roof.

I'm sorry, I was keeping you up. I always forget that other people live in different time zones. I will get back with you later today. I have to go meet with the contractor right now.
Expert:  StructuralEng replied 1 year ago.
No problem. I'll look for your follow up.
Customer: replied 1 year ago.
So, I have a beam. The guy tells me that it is a w12x48. I can't find that in my book. I would like to span it as far as possible. Would 21' be ok? The W12x45 says 20' and the W12x50 says 21'.
Customer: replied 1 year ago.
So, it is a W12x45. What would the post spacing be on that?
Expert:  StructuralEng replied 1 year ago.
Thank you. I will look back at the sketches and get back to you this afternoon.
Expert:  StructuralEng replied 1 year ago.
If it's a single 40' long beam, then a post at each end and one at midspan will work for you.
Customer: replied 1 year ago.
Thank you
Expert:  StructuralEng replied 1 year ago.
No problem. Good luck with your project
