If you have exposed rebar and a listed connector that should work for the inspector for the basic bonding. I would really want to see <1 ohm with a simple continuity test (rebar to ladder cups) but it would be better if you loaded it a bit. I would trust my Ecos tester. Maybe with the right adapter a Suretest would work too, never tried it.
I am curious, what are you using to splice the #8 at the intersections? Bugs will work but that will be pricy. I think I would beat up the internet and suppliers to be sure someone has't come up with #8, 12x12 welded copper mesh. It is the logical product for this application.
