Autonomous pre-dig subsurface intelligence for private-site excavation.

The problem

Construction teams still dig half-blind.

Deep excavation with timber shoring, crews, and heavy equipment on a construction site.

More than 20,000 utility strikes occur each year due to incorrect or incomplete markings, driving over $30 billion in utility damages annually. Underground uncertainty still causes delays, cost overruns, and dangerous strikes — and the process for knowing what’s beneath before excavation remains slow, fragmented, and unreliable.

Private utility uncertainty

811 covers public utilities — but private campus networks, internal conduits, and undocumented infrastructure remain invisible until the bucket hits them.

Delays, redesign, and rework

Unexpected underground conflicts force schedule stops, emergency redesigns, and costly rework that cascades through every downstream trade.

Strike risk and liability

Utility strikes cause explosions, service outages, environmental damage, and injuries. On private sites, the liability falls directly on the contractor and owner.

How Tracer works

From scan to deliverable in hours, not weeks.

01

Scan the site

Deploy Tracer to autonomously traverse the work area with ground-coupled GPR and EMI, collecting dense subsurface data on a precision survey grid.

02

Fuse subsurface + positioning data

RTK GNSS, LiDAR SLAM, and IMU fuse with GPR/EMI returns to build a spatially registered underground dataset with centimeter-level accuracy.

03

Detect utilities and confidence zones

Edge AI and physics-informed models identify buried utilities, classify material types, and assign confidence scores to every detected object.

04

Export engineer-ready outputs

Deliver CAD/BIM/GIS-ready utility maps, confidence-scored risk zones, and pothole recommendations directly into existing SUE and contractor workflows.

Subsurface visualization

Tracer fuses GPR, EMI, and precision positioning to build a spatially registered map of buried utilities — color-coded by type, scored by confidence.

Why teams choose Tracer

Built for the firms that own underground risk.

Tracer is a force multiplier for SUE firms and contractors — not a replacement. It handles the repetitive fieldwork so your experts focus on judgment.

Demo

Tracer in motion

Autonomous traversal and subsurface sensing on site — the same rover-first workflow, in action.

Faster field collection

Cover more area per crew-day with autonomous scanning. Less manual cart-walking, more coverage.

Repeatable scans

Consistent scan density every time. No technician-to-technician variability, no missed zones.

Lower interpretation burden

AI handles first-pass analysis so your senior experts focus on QA and judgment, not repetitive radargram reading.

Cleaner deliverables

Engineer-ready digital outputs with confidence layers, not raw data that needs hours of manual processing.

Technology

Six layers of integrated intelligence.

Each layer of Tracer's sensing, positioning, and AI stack is purpose-built for subsurface utility intelligence.

Ground-coupled GPR

Stepped-frequency continuous wave radar with multi-channel arrays for deep, high-resolution subsurface imaging through varied soil conditions.

Electromagnetic induction

Active EMI sensing detects conductive targets and conductivity changes that GPR alone cannot resolve, completing the underground picture.

RTK + LiDAR SLAM

Tightly coupled GNSS, IMU, LiDAR, and odometry deliver centimeter-accurate positioning even in GPS-challenged environments.

Edge + cloud AI

On-board inference for real-time detection with cloud-based deep processing for final utility classification and confidence scoring.

Confidence-scored outputs

Every detected utility gets a classification confidence, material estimate, and depth range — enabling risk-based excavation decisions.

Autonomous path planning

Coverage-optimal navigation autonomously drives scan patterns across the site, ensuring complete subsurface mapping without manual guidance.
