Verifying an existing footing
Verifying an existing footing
(OP)
I have been asked to extend an existing 6' opening in a CMU wall to 12' width. The problem is there are NO drawings of any kind for the building. It is a 15 story block and plank construction hotel that is 36 years old. Verifying the CMU strength and reinforcing is relatively straight forward with xrays and core samples. But the footing is the problem. How to find the size, reinforcing and concrete strength of the footing without totally demolishing the slab and footing. It almost seems as if the resulting gain (larger gift shop entrance) does not justify the means to get there. Any ideas?

For that age and size of building, there should be drawings somewhere to get a permit and build. It just takes detective work and a little time. - Much cheaper than digging and assuming extra liability.
