We're looking at having the upper deck built on our walkout basement finally. A few years after we moved in we put in a stamped concrete deck downstairs, and when we did that we had them put in concrete pilings for the eventual top part of the deck.
Now that I'm thinking of doing the top part I'm thinking of the permit and what they'll need. I'm not sure if "sure we did them 15 years ago" will cut it. I couldn't find any pictures of when they were doing it either.
This is the idea
Though we're only doing the part on the left hand side of the render, not the part across the back or on the right hand side.
The pilings are at the 45 degree corners where the cantilever starts and then one half way between those.
Any ideas on how to "prove" they exist for the purposes of a permit?
My only two ideas are to either dig from the sides of the deck enough to expose the pilings or to drill though the top with a long enough concrete drill to verify it's concrete down far enough. The ones on the sides seem like wouldn't be that much digging but the one in the middle might be tougher (that's almost 2' of overhang).
The concrete drill they're going to have to drill holes for the things to mount the poles anyway but I'm kind of doubting they'd have a concrete drill bit long enough, and not sure pictures of that still bringing up concrete instead of dirt would be enough for a permit.
Sonar imaging??
Any other ideas? Or am I hooped?
