So I've been asked to do a new floor over an existing floor and have a couple of questions for you guys.
1. When you design a floor over an existing one, do you just treat the new floor as completely separate and span the new joists and such or do you rest them on top of existing? I'm thinking design the new floor as separate because it does add weight.
2. How do you know where you need blocking? You need it at panel edges right? Are the panel sheets normally 48" wide or? So do you just call it out at 48" o.c. blocking lines?
Thank you!!
