Crew rolled in ready to pour, and the feed they thought was sitting under that west lot turned out to be a dead-end stub. No usable path forward. Owner’s looking at us like we caused it. We didn’t. The original run was abandoned years back and nobody updated the prints.
The situation described in Python/C++ library for distribution power system analysis, “They Broke Ground and Found the Old Utility Feed Had No Path Forward” reflects a growing pattern across commercial environments where assumed infrastructure simply isn’t there once the dirt opens up.
That’s the part property owners don’t always hear about. A commercial underground utility install is not just trenching a line from point A to point B. Half the work is figuring out what the previous contractor left behind, whether the conduit path still exists and if the utility side can even land a new feed where you need it. Old PVC collapses. Direct burial cable gets pinched. Sleeves get crushed under fill nobody documented.
On this job we ended up rerouting through a fresh bore along the property edge, new conduit, new pull boxes, coordinated with the utility for a proper service entry. Took longer. Cost more. The alternative was patching into something already failing.
If you’re planning a build and the prints show an existing feed, verify it before you break ground. Pothole it. Camera it. Don’t assume.
