Utility Potholing and Locating in Abilene, Texas

A paint mark on the pavement says a line is probably here, within some tolerance, and the only way to know exactly where is to look. Potholing with a vacuum excavator opens a small, clean window to a buried line, measures its depth and position and closes again, which is why it has become the first step of nearly every trenching job we plan in Abilene. Locating without potholing leaves the contractor guessing, and guessing near a gas main or a fiber trunk is expensive.

The one-call center tells us who has lines in the work area, and each owner marks what it knows. Marks are approximate, abandoned lines may not be marked at all and private lines on campuses and industrial yards are frequently missing from any record. Potholing fills the gaps, so that the design team can adjust a route or a depth before the trench is open, not after a backhoe has found the pipe.

Specialist locating and vacuum excavation partners work under our management, and the results are surveyed and delivered as a table and a sketch to the engineer. The concrete trade partners then restore each pothole location to the surface standard the owner requires.

What potholing costs and what it saves

Potholes are priced per hole, with variations for depth, pavement type and traffic control. Cutting through a thick concrete slab or a deep base takes longer than opening a lawn, and a pothole in a busy street needs lane closures and flaggers. Even so, the cost is small compared with the cost of one damaged main.

We look at potholing as insurance with a record. A line that is found at four feet instead of three changes the pipe invert, and a conflict discovered early may mean a minor design adjustment, not a change order and a stop-work order in the middle of the trench. We recommend potholing at every crossing and at every tie-in point, and on a municipal building site with old campus lines we recommend it along the whole proposed route.

Deciding where to look

The engineer and the contractor pick pothole locations from the utility plan: crossings, tie-ins, proposed structure locations and places where the record is unclear. We add extra holes where lines run parallel to the proposed trench, because the edge of the trench is often closer than expected.

Soil matters. Clay holds a clean vertical wall and is easy to vacuum, while sand slumps, and caliche may require air or water to break loose. A pothole in heavy clay can be completed quickly; a pothole in rocky fill takes more time. A roughly $125 million project would widen Interstate 20 in Taylor County from FM 600 to SH 351 to six lanes and add an overpass at Judge Ely Boulevard, with construction slated from October 2026 to late 2029. Highway work of that scale makes accurate utility information along the corridor especially valuable, since every line in the way is a potential delay.

Why potholing is safer

Digging blind near energized or pressurized lines is among the leading causes of serious injury in utility work. Vacuum excavation removes soil without a metal tool on the line, which eliminates most of the risk of striking a gas pipe or a power cable. We pair that with a briefing, a marked work zone and a spotter.

Our procedures include verifying marks before each hole, using non-metal tools for the final exposure, avoiding contact with lines, photographing each exposed line with a scale and backfilling with approved material in lifts. If a line is damaged or found leaking, the crew stops, secures the area and calls the owner and emergency services at once.

Records the design team can use

Each pothole is numbered and recorded with the owner of the line, its material and size, depth to top, horizontal position tied to a survey point and the date. We deliver the record in a table and on a sketch, and where the project uses a coordinate system the survey is tied to it.

We also keep photographs of the exposed line, which engineers rely on when they compare conflicting records. If the plans call for the line to be moved, the same data starts the relocation design, and our page on utility relocation explains how we sequence it. For sizeable projects the information feeds site utilities planning directly.

Fitting into the project calendar

Locate requests carry lead times set by law and by each owner's response. Tickets go in the moment the work area is drawn, and we plan potholing after marks are placed and before design is finalized. Marks expire, so the work must follow within the ticket's life or the ticket must be renewed.

Abilene Regional Airport has two asphalt runways of about 7,200 feet each, and a new 130-foot control tower was completed in January 2012. Work near an airport needs advance coordination for access, equipment height and security, and we ask about those rules during scheduling, not at the gate.

Reaching jobs across the region

U.S. Routes 83 and 277 run together through the southwestern side of Hawley, leading about 13 miles southeast to Abilene and 11 miles northwest to Anson, and projects along that corridor often involve long linear utility records that are better confirmed with a series of pothole probes than a single survey. We mobilize to Abilene and the US 83 and US 277 corridor.

Ranger lies on Interstate 20 between Abilene and Fort Worth, with interchange exits 349, 351, 352 and 354, and the highway is a common route for fiber and pipeline crossings. Where we pothole beside the interstate, we coordinate with the state's right-of-way rules and traffic control requirements.

A region with layered infrastructure

Throckmorton has long served as the market center for the county's oil and agricultural business, with cotton gins and flour and feed mills among its industries. Older commercial centers like it often have abandoned pipes from earlier uses, along with newer lines laid in the same corridors. Lake Brownwood State Park was developed beginning in 1934 with the Civilian Conservation Corps, and recreation and public lands include buried systems of their own.

Utilities and energy companies know this better than anyone. Because layers of infrastructure were added over decades, the records seldom agree. We take that as a reason to look rather than assume, and we make the findings available to every trade on the project through the conduit and fiber trenching and utility teams.

Common Questions

Is a locate ticket enough without potholing?

Marks are approximate and do not cover private or abandoned lines. Potholing confirms depth and position at the places that matter and is the best protection before a trench or boring.

How big is a pothole?

Typically a small round or square opening, often a foot or two across. It is backfilled and restored the same day wherever possible.

Who is responsible if a marked line is wrong?

Responsibility depends on the damage prevention law, the contract and whether marks were followed. Our records of ticket numbers, marks and photographs support any review.

Can you pothole through pavement?

Yes. Pavement is saw-cut or cored, and after exposure the hole is backfilled and patched with concrete or asphalt to match.

How soon do you deliver results?

Results from a day's work are normally compiled within a few days, faster for urgent design decisions.
