I had to move the underground feed to an existing building due to a new building is going up and will sit right in the path of the existing service. POCO doesn't allow you to build over their service lines. POCO came and marked where the line was. Only thing I was going to keep from existing was the sweep from the meter. Plan was to cut the wires and cut the coupling off, then turn the sweep 90 deg to receive the new UG feed. I had POCO cut power at the transformer as I was going to cut the wires at the sweep and remove them from the meter.

When trenching for the new run, the trencher guy called me over to look at something. It was the existing run from the transformer. No marking tape, just their flex conduit and service wires. This was at least 50' from where they marked it, and in an entirely different route! Good thing the power was cut as the bucket severed some of the wires. I don't know how the POCO got this so wrong. I asked the POCO project manager and his reply was "it happens sometimes".

It wouldn't do any good to call 811 dig if they're going to be that far off on their marking!

In my area all of the utilities have hired third party locating contractors.
After we cut a 100 pair phone line that was more than 20' from the locator marks, I was talking with the AT&T splicer, and he told me at first they were all pissed off after AT&T gave that work to the third party contractor, but no so much now as they are getting a lot more over time to fix cables that were not correctly located.
