Why we hand-dig near utility marks: the 24-inch rule

The first thing that happens on our job sites when we arrive is getting a good lay of the land and seeing what we are up against. Before a single machine touches the ground, we walk the entire area to verify and document the existing utility marks.

Every job starts the same way, walking the site before anything gets dug.

Those flags are the whole story

Before we ever showed up, the utilities were marked out through the 811 one-call system. Those little colored flags and paint lines tell us exactly where the gas, water, electric, and fiber run underground. Red is electric, yellow is gas, blue is water, orange is communications and fiber. They are the map for everything you cannot see, and we treat them like it.

The 24-inch rule

If you ever spot our crews working, you will notice one of the first things we do is measure at least 24 inches off the other utilities' flags. That tells our operators where they can work up to safely with a machine. It also tells us where we need to get some of the laborers set up to dig and expose those areas by hand, because anything closer than that cannot be safely dug with an excavator.

It slows us down a little on the front end, and we are fine with that. Hitting one of those lines is dangerous and expensive, and it is almost always avoidable when you take the time to find it first and dig it out by hand.

The part nobody sees

This is the part of the job nobody thinks about until something goes wrong. We would rather spend the extra hour with a shovel than explain to a homeowner why their power is out or why the street lost water. Careful is not slow, it is just doing it right the first time.

If you are planning any kind of dig in Sussex, Warren, Morris, or Hunterdon County, always call 811 first, and know who is working in your yard. If you need a crew that treats your property and your utilities like they matter, call us at 862-268-2510. More on the underground work we do is on our utility construction page.
