I think you can see why I am a bit reluctant to use PME on the EVC points although it is inside the building.
Why do we assume that the concrete floor inside the building is on PME potential and so the EVC can be on PME?
The shoes that are not conductors cannot prevent the current going through the human body into the earth?
Or they are too flimsy to prevent the current running through them
It’s not unusual get an electric shock from a car with an internal combustion engine when you touch it due to static

OMS, silly questions....

OK - if you decide to go for a TT supply to the EVC's how do you segregate the TT electrode from the earthy frame of the building which has PME for all the other services.
Consider if it would be safer making arrangements to connect the rebar under the vehicle areas to the MET and retaining PME to supply the EVC - what potentials would exist between the vehicle body and the floor slab that a person might actually bridge between hand and foot in either case
