Carport using unusual construction method

Interesting build and nice old truck! What did you use for footings for the pillars? Also you say "large"........I said the same about my shop and it's 24x28.......now I wish I had gone twice that size. lol
Hi, Rusty, and thanks for chiming in.

The footings consist of 12 three-foot-deep concrete-filled postholes, in which are set lengths of 3"-diameter, 3/16"-wall steel pipe. The columns are poured around the pipe and the pipe is also cement-filled.

My shop is the building next to the carport. I'm hoping that parking as many cars as possible in the carport will give me a lot more space in the shop.
