Same here, permit, electrical inspection then pour.
Ufer is required for any foundation work of 20' in length by local code.
A concrete-encased electrode as defined by Section 250-50(c) shall be installed at each new building or structure, and for existing buildings or structures when a new or replacement foundation footing with a perimeter length of 20 feet (6.096 m)is installed.
And yep, often the electrician is responcable for install and inspection. A GC can pull the permit and install, but must get the Electrical Inspector out. Many will opt for the electrician to do it, cause they don't want to be hassled on the inspection if they mess it up. Wrong connections, or one guy who installed insulated wire... Then have to hold up a pour. Some have made the mistake of not doing a Ufer at all, and had to break out the demo hammer... It is actually nice because this little bit of work early in projects kinda locks you in for the rest of it. Usually we do a wire electrode rather than rebar, cause we have had concrete workers cut or re-arrange the rebar after we're gone. If the see the wire, they tend to leave it alone. And seeing that often the area where the wire would exit the foundation is often in a finish wall, we just use a long enough wire to go all the way to the equipment later. So there is no connection to made.
