What about the other trades involved? If this was a covered carport like it looks, the roof would have to be patched and probably the drywall in the overhead of the garage torn down to access the conduit. And how much does poco charge to come out and move their box and the aerial? Actually, if this was all new, they would have to come out twice- once to take the box and aerial down so the garage could be built, and again to put it back up. Meanwhile, for the length of the job, plus time for the inspectors and poco to come back out, the homeowners are either completely without power, or have to rent a sizeable generator. So, write off all the food in their freezer!
I agree that $10k is a way high estimate, I just threw that out there without much thought. But it's not going to be cheap to move a meter, that's for sure. And a royal pain in the butt! Aside from that, it looks like that garage would have had exactly 0 impact on like in the rest of the house during construction. Constrast that with at least several days, if not a week without power.
