Will AI Replace Utility Locators? Underground Pipes Do Not Care About Algorithms

15% automation risk. In a world obsessed with digital transformation, utility locators are a reminder that some of the most important work happens where no amount of cloud computing helps — underground, in the dirt, with a handheld detector and a can of spray paint. The data is unambiguous: this is one of the safer trades to be in as AI reshapes the rest of the economy.

If you locate underground utilities for a living, here is what the data actually says about AI and your career.

The Ground Truth About AI Exposure

Utility locators face 30% overall AI exposure in 2024, with a modest automation risk of 15%. [Fact] By 2028, exposure is projected to reach 50% and risk to climb to 31%. [Estimate] These are medium-range numbers that reflect a job being augmented, not replaced.

Operating electromagnetic and ground-penetrating radar equipment — the core field task — has just 25% automation. [Fact] The equipment itself is becoming smarter, with AI-enhanced signal processing that can better distinguish between different types of underground infrastructure. Radiodetection, Vivax-Metrotech, and Sensors & Software have all shipped equipment with onboard signal classification in recent product cycles. [Claim] But someone still needs to physically walk the site, position the equipment, deal with terrain variations, and interpret signals that are often ambiguous. A utility locator working in a dense urban area with decades of overlapping infrastructure knows that what the machine shows and what is actually underground are not always the same thing.

Interpreting utility maps and GIS data to verify line locations sits at 52% automation. [Fact] This is where AI contributes most. AI-powered GIS systems can overlay multiple data sources, cross-reference historical records, identify probable utility paths, and flag potential conflicts before the locator arrives on site. Esri ArcGIS, Trimble's positioning solutions, and platforms like Overlay and KorTerra have moved into the daily workflow of larger locating operations. [Claim] What used to require hours of manual map review can now be partially automated. But the word "partially" matters — utility records are famously incomplete and inaccurate, especially for older installations.

Documenting and reporting located utility positions has an automation rate of 35%. [Fact] Digital mapping tools, GPS-integrated documentation systems, and automated reporting platforms are making the paperwork faster and more accurate. The Common Ground Alliance's Best Practices for damage prevention have been steadily updated to incorporate these tools, and industry trade groups have pushed for standardized digital deliverables that integrate with one-call ticket management systems.

A Growing Field With Real-World Demand

According to the BLS Occupational Outlook Handbook for Construction and Building Inspectors (SOC 47-4011) — the broader BLS category that includes utility locators — there are about 147,600 workers in this occupation as of 2024, earning a median annual wage of $72,120, with the lowest 10 percent earning under $46,560 and the highest 10 percent over $112,320. [Fact] BLS projects a -1% employment change from 2024 to 2034 for the parent category, but still about 14,800 openings per year on average over the decade as workers retire or transfer out. [Fact] Utility locating as a sub-specialty within that category clusters at the lower end of the wage range, reflecting the field-based, technician-tier nature of the work, with regional OEWS surveys placing many locator roles in the $45,000-$60,000 band.

The growth driver is simple: infrastructure. Every new construction project, every road repair, every fiber optic installation, every water main replacement, every renewable energy interconnection requires someone to mark what is already underground before digging begins.

The Infrastructure Investment and Jobs Act of 2021 directed hundreds of billions of dollars toward roads, bridges, water systems, broadband expansion, and grid modernization — and that flow of project funding is only now translating into the field-level work that keeps locators booked solid. [Fact] Add to that the steady drumbeat of fiber-to-the-home buildouts driven by federal Broadband Equity, Access, and Deployment program allocations, and the demand picture stays robust through the end of the decade.

The consequences of getting it wrong are severe and immediate — ruptured gas lines, severed fiber optic cables, flooded construction sites, even fatalities. The Pipeline and Hazardous Materials Safety Administration tracks excavation damage incidents in detail, and the human, financial, and regulatory costs of a missed locate are enormous. [Fact] The one-call system (811 in the United States) exists precisely because this work is too critical to skip or approximate.

Why Full Automation Is Not Coming

Several structural factors protect this occupation. [Claim]

The physical environment changes constantly. Weather, soil conditions, surface obstacles, and site access are different every day. Locators routinely work in rain, snow, mud, and triple-digit heat, with vehicle traffic to navigate, dogs in fenced yards, and construction crews waiting impatiently to start digging. Autonomous systems built for controlled environments do not handle this kind of variability cost-effectively.

Underground infrastructure records are notoriously unreliable. Utilities installed decades ago may have no records at all, or records that have been digitized with errors, or maps that were redrawn during multiple ownership transfers and lost meaningful detail along the way. The locator's craft is partly archaeological — combining whatever maps exist with electromagnetic signals, visual cues at the surface, and conversations with property owners and utility employees who remember where things were buried.

The liability framework requires human judgment and human accountability. When a locate is marked, a professional is certifying those marks with their expertise and their license. State regulations and industry standards require named responsible parties for excavation safety. AI assistance is welcome; AI as the responsible party is not.

Damage prevention culture is built around human relationships. Locators interact constantly with utility company representatives, excavator operators, project managers, and homeowners. The trust and communication patterns that prevent damage events are deeply human. Locating contractors that try to remove this human layer in pursuit of efficiency tend to see their damage rates spike.

The pattern of AI use in this field matches the broader category trend documented in the Anthropic Economic Index (2025), which finds that construction, extraction, and installation occupations register some of the lowest shares of AI-mapped tasks in the entire economy, and that within these clusters AI usage skews heavily toward augmentation rather than automation. [Fact] AI makes utility locators more productive and more accurate. It does not make them unnecessary.

Industry Verticals and Specialization

Locating work breaks down across several segments with distinct demand profiles:

Public utility locating — the work performed by utility company employees or their contractors in response to one-call tickets — is the largest segment by volume. It is steady, well-regulated, and increasingly digitized.

Private utility locating is a higher-margin specialty for finding lines that the public system does not mark — irrigation, septic, private power runs, lighting circuits, and fiber on private property. Demand for private locating has grown sharply as commercial real estate and large residential properties recognize the risk of their unmarked infrastructure. [Claim]

Subsurface Utility Engineering is the highest-skill tier, combining locating with engineering judgment for project planning. ASCE 38-22 quality levels (A through D) define the standard, and SUE practitioners working at Quality Level A — physical exposure of utilities — earn premium rates.

Damage investigation and forensic locating is a specialty for after-the-fact incident analysis. Locators experienced in litigation support, regulatory investigations, and insurance claims work command higher daily rates and more interesting cases.

Career Advice

If you work as a utility locator, invest in learning the AI-enhanced tools entering your field — digital GIS platforms, AI-assisted signal interpretation, and automated documentation systems. The locators who combine field experience with technology fluency will be the most valuable. The work itself is not going away.

For workers entering the trade, the path is reasonable. Most locators learn through a combination of vendor training (manufacturer certifications on specific equipment), employer-led programs, and apprenticeship-style time in the field. National Utility Locating Contractors Association certifications and Common Ground Alliance training resources provide credible credentialing paths. Wages in higher-cost markets, particularly the Mountain West, Pacific Northwest, and Northeast, push well above the national median. [Claim]

The trade rewards patience, attention to detail, and the willingness to be outdoors in conditions that office workers would consider miserable. AI is not changing those requirements. It is just giving the locator better tools to do the job that still has to be done by hand.
