    UFER gone after framing

    Get to new residential build to install permanent service. Find that the framers cut off the UFER flush with the top of the poured wall and installed the pressure treated
    2"x8" top plate over it.

    Will 2 driven 5/8" x8' galvanized rods suffice for the Grounding electrode?
    Incoming water is plastic.

    Can the AHJ require that a CEE be put in after the fact?

    Thanks

    The CEE still exists. You have to use it. The piece of rebar the concrete guys left for you is just for your convenience. It is not part of the CEE.

    You need to let the GC deal with this financially.

    Just remember
    Do not talk about any discussion topics that could/should occur with the framers.
    Otherwise words like "premeditated" get thrown around.

    Someone (not necessarily you) will have to chip into the foundation wall and make the connection to that rebar. Yours is unlikely to be the butt soon to be in a sling.

    if anyone chips into the concrete it will need to be properly repaired and re-inspected. If the panelboard is in the basement it might be simpler to access the CEE connection from the inside.

    OP, was this a rebar stub or a CU wire?

    As I read this, the OP says the conductor tied to the UFER is inside the poured concrete wall that is on top of the footing.

    If I could reasonably designate the place on the wall that the Grounding Electrode Conductor is in, I'd expect them to expose enough of it to install a non-reversible crimp.

    Around here it is allowed to create another concrete encased electrode next to the footing with 20 feet of rebar or #4 wire encased in 2 inches of concrete. You would not have to break up concrete since the last sentence of 250.52(A)(3) states that where more than one CCE is present at a building, only one needs to be bonded to the grounding electrode system.

    It was a rebar stub.
