Going to be building an attached 16 X 16 deck soon. I already spoke with the building inspector about footings and he gave me some calculations on the size and spacing of the footings but I'm in need of help with one calculation.
Apparently I will need footings at the base of the stairway but I don't know how to calculate the location of them, or how high to pour they so that they match up with the bottom of the stringer. The deck is going to be between 5 and 6 feet from the ground at the location of the staircase but I'm not exactly sure because the landscaping is not done yet and the final grade has not been determined.
It would be easiest to just pour those footings after the deck is built when I can line up the stair stringer to the ground, but that would mean renting a power auger twice and I'm trying to be as cost effective as possible.
I thought about pouring them low and then using short posts to attach the stringer to the footing, but then we're talking about direct soil contact to the wood which someday is going to result in rot.
Any advice on how to figure this out?
Also, what is the advantage of using cardboard form tubes vs just pouring the concrete into the hole?
Thanks.
