Caisson Foundation in the Way
Caisson Foundation in the Way
(OP)
I've got a building in Florida where the architect has designed the perimeter of the building to wrap around an existing billboard so that the billboard is within about 8.5 inches of the exterior CMU wall. The edge of the existing caisson would extend about 6 inches under exterior wall. I'm thinking of using a transfer beam to span over the existing foundation because any deflection in the billboards foundation will heave my wall otherwise. However, this is a perimeter wall with the top of the caisson at grade. Is there some sort of void form-ish product that will provide the required weatherproofing here? I've attached a quickly redlined plan view of this section and a section of what I'm currently thinking.. This is sort of out of the box for me, so if I'm completely off base here don't be afraid to let me know. Thanks all.

At the highest point of the building at the worst case hurricane wind condition from the worst possible direction?
[Now, the question is: How much credit can you take for the building moving the same direction as the sign under wind loads when the sign is being pushed towards the building? 8<) Will the building ever be more flexible than the sign - so the building hits the sign when the eye has passed, and the building is being blown into the sign post? ]
