The infamous and elusive UFER

[zbang]

I'm still back on which codes require the construction of a CEE. Do some state building codes or electrical code amendments? Not the NEC AFAICT.

Art 250.50 says "All grounding electrodes as described in 250.52(A)(1) through (A)(7) that are present [...] If none of these grounding electrodes exist, one or more of the grounding electrodes specified in 250.52(A)(4) through (A)(8) shall be installed and used." CEEs are (A)(3). It's a long stretch to argue that none are present when the structure hasn't been built, but even then making a CEE isn't needed.

Are you saying that even with the qualifying rebar it isn't required? Without the qualifying rebar you do not have to use it.

Are there any "Good Engineering Practices" papers for installing UFER systems?
Or is it up to the concrete contractor to do it correctly?

...

I don't think any national or international code requires a CEE *per se*, but many codes require concrete to be reenforced and thus effectively require creating a CEE if doing a concrete foundation. Or at least they did before the vapor barrier requirements got put in. But the enforcement of having the CEE and GEC installed before pouring is local rules or enforcement decisions.

You can also always build a structure on something else like steel pilings, which is one reason a CEE won't ever be universally required.
