"ufa ground"???

Did you mean ufer ground? In NEC terminology, it is a concrete-encased electrode, or CEE for short.

Typo or not, I'm not getting a full picture in my mind. Describe exactly what the apprentice cut—using NEC terminology—and where?
 
Jog, we don't have enough information to answer your question. Is the Grounding Electrode Conductor (GEC) run first to something other than the Concrete Encased Electrode (CEE or ufer), or does it go from the Service Disconnect Main Bonding Jumper to the CEE?

If this question is confusing, ask further questions, please.
 
Believe it or not I've heard guys call it a 'ufa' before.

If he cut it off at the top of the concrete, just gently drill and chisel away enough concrete until you can get an irreversible crimp on there. :D

He cut the ufer ground as it comes out of the foundation below the panel, because the panel set low,he cut about 4 inches off.

Is there still enough left to get a connection on? If yes, connect and move on.

Agreed. If the "4 inches" was trimming the "ufer ground" to make a more workman-like connection there is no issue.

If the "4 inches" is cut out of the middle of the exposed conductor, there is still no issue if you splice the two pieces together with an irreversible means listed for grounding and bonding -- 2014 NEC 250.64(C).
 
I agree with the others the concrete encased electrode or UFER ends where it exits the concrete so you can tie a grounding electrode conductor to it.

250.68(C)(3) A concrete-encased electrode of either the conductortype, reinforcing rod or bar installed in accordance with
250.52(A)(3) extended from its location within the concrete
to an accessible location above the concrete shall
be permitted.

It's worth noting that under the 2014, a wire type CEE would not require an irreversible splice, under the 2017 it will. The piece sticking up is covered under 250.68(C).

ETA:
2017 NEC 250.68(C)(3) said:
A rebar-type concrete-encased electrode installed in accordance with 250.52(A)(3) with an additional rebar section extended from its location within the concrete to an accessible location that is not subject to corrosion shall be permitted for connection of grounding electrode conductors and bonding jumpers. The rebar extension shall not be exposed to contact with the earth without corrosion protection.

Are you talking about a piece of rebar stubbed up? Regardless of whether it's a wire or rebar why do you think there's a minimum length for accessing it?
