The Ufer (concrete encased electrode) is now in our building code too and that eliminates the need for a made electrode like a rod. I have both types of electrode here all bonded together with #2 copper, just because I came up with a bunch from a botched computer room built. I bonded the footer steel on my addition and connected it to the GES. Perhaps my biggest Ufer is an inground concrete pool but you can't say that out loud. NEC purists have their hair catch on fire if you do. Copper doesn't lie tho. There are multiple connections between the MBJ and the pool, mandated by the various code sections referring to grounding and bonding.
