The inspector walked the site, looked at the trench, and shook his head. Depth was off in one stretch, and the bedding wasn’t right for the conduit we were running. So the line came out, the path got recut, and we started over before the meter could be set. Nobody likes redoing work. But skipping it costs the owner more down the road.
Electrical demand is changing faster than many buildings can keep up. That’s the real story behind the recent CNET, “Amazon’s Spring Sale Is Almost Over, but There’s Still Time to Save Up to $2,497 on Power Stations” piece. People are buying portable backup because they don’t fully trust what’s already in the ground. Portable units don’t fix what a bad underground utility install creates.
Trench work looks simple from the road. It’s not. Depth matters. Separation from water and gas matters too. Conduit slope, sweep radius, bedding material, warning tape placement, all of it gets checked. Miss one piece and the utility won’t energize the service. That’s how a meter set slides a week.
We’ve seen contractors backfill before inspection, then dig the whole run back up. Expensive lesson. On a commercial site with paving above, worse.
Most of the time the redo isn’t about the electrician. It’s about who scoped the trench, who set the depth and whether anyone verified the route before the dirt went back. If the new construction crew rushed it, the underground guys pay for it. So does the owner.
FAQs
Why does a trench need to be redug before the meter is set?
Usually depth, bedding or separation from other utilities was off. The utility company won’t energize service until the route passes inspection.
How deep should a commercial underground electrical run be?
Depends on conduit type, cover requirements and where it’s running. Most commercial runs sit between 24 and 36 inches. Under traffic areas, deeper. Always follow what the AHJ requires.
Can a bad trench be fixed without digging it back up?
Sometimes, if the issue is small and still accessible. Once it’s backfilled and the problem is structural, you’re digging.
Does this delay the rest of the job?
Yes. A failed trench holds the meter, the meter holds the power, and the power holds everything that needs it to finish. The new service installation sits idle until the underground passes.
Who pays for the redo?
Depends on the contract. If the trenching sub missed spec, it’s usually on them. If the spec itself was wrong, that goes back to the design side.
