Construction & Excavation Safety

See every underground line
before you dig.

Subtrace maps water, gas, electric, and sewer utilities in real time. Aggregates 811 data, private lines, and depth information into one live view — so you know exactly what's underground before the first shovel hits dirt.

Old maps. Approximate marks. Expensive mistakes.

811 only covers public lines

Private utilities — the lines on your site that aren't owned by the city or utility company — are invisible to the 811 system. About 65% of on-site utilities fall into this gap.

Old records, wrong locations

Many municipal utility records are decades old. Utility lines shift from soil movement, repairs, and new construction. What the map shows and what's actually in the ground often don't match.

No depth data from markings

811 flags tell you where a line is approximately, but not how deep it runs. A gas line marked at 18 inches can actually be at 3 feet — and directional drilling doesn't know the difference until it strikes.

One map. Every line. Real time.

01

Aggregated utility overlay

Pulls in 811 ticket data, municipal records, and field locate reports into a single unified layer. No more switching between five different systems to piece together what's underground.

02

Private utility coverage

The 65% of underground lines that 811 doesn't cover — your private laterals, campus utilities, site-specific infrastructure — are mapped using field data and contractor contributions.

03

Depth-aware visualization

See not just where utilities run, but how deep they sit. Color-coded by estimated depth so you can plan your excavation approach before you break ground.

04

Field-ready on any device

Works on the laptop in the site trailer, the tablet in the field, and the phone in your hand. Real-time updates when locators file new data or utilities are exposed.

Utility layers, not a guessing game.

Every underground line rendered as a distinct, color-coded layer. Water in blue, sewer in green, gas in yellow, electric in red. Toggle layers on and off, zoom into the work area, and see exactly where your excavation path intersects with critical infrastructure.

Built for the people who dig.

Excavation Contractors

Know what's in the ground before you trench, directional drill, or pothole. Reduce strike risk, avoid rework, protect your crew.

Project Engineers

Site planning and civil design backed by accurate subsurface data. Specify trench paths that avoid utilities before construction begins.

Utility Companies

Push as-built data to a live map, reduce mislocates, and give field crews a single source of truth for your network assets.

Municipalities

Digitize aging utility records, streamline 811 coordination, and give inspectors live data during infrastructure projects.

The next dig doesn't have to be a guess.

Subtrace is building the comprehensive underground utility map for every excavator and contractor in the United States. Every water line, gas main, electric conduit, and sewer lateral — visible before you break ground.
