How Create Accurate Footing Layout Plan?

Off Topic
1

Folks, I’m going to build and ship this nice kit for one of my azumaya designs, all the main structural part anyway, except this one also has a surrounding awning type roof all 4 sides of the building, which adds a lot more posts for the footing layout! The Posts all sit on raised concrete columns (1e.png) and we need them placed accurately.

I can create my normal plans for the footing layout, with a normal square or rectangular building it’s pretty easy and easy to follow, but with the additional offset Posts it’s getting confusing!

as you see in 1d Layout.png, I can locate the exact centers of the post / footings. I’d like to give his concrete contractor some sort of accurate file, so what’s the best way to do this? Is there some sort of point cloud a surveyor can use?

From a builder’s perspective, here’s what I would take to the job with me in addition to what you have shown.

So could a surveyor use a dxf or dwg, or some other file type I can export from SUp?

I don’t see why not. Couldn’t they also just use a printed plan from jpg or png?
Most of the surveyors I have known are pretty clever folk.
Again, my answer was based on what I’d use as a builder, I don’t know exactly what a surveyor might prefer.
