Our project is required (by code) to raise the elevation of the ground floor slab, to account for future sea level rise. Because there are numerous (very, very numerous) floor boxes in the slab, it makes more sense to demo the existing slab and reconstruct a new one, at a higher elevation.
Has anyone any experience with this - would we qualify for the exception to exclude this area from the calculations?
Thanks!

Deborah - I responded to your inquiry below, but just saw your post. In our case, we did NOT include the exisitng foundation in our calculations, only the structural elements that were preserved. Maybe someone else has more direct experience, but I would guess you would be hard pressed to exclude the slab. And maybe I'm picturing your project incorrectly, but maybe you could leave the existing slab in place, add the new floor for the raised structure, but incorporate the slab somehow -- even if it's just empty space? Just brainstorming -- Good luck!

Erica,
yours is the approach I was advocating as well.
We shall see.
Thanks!
