HAL is the field tool built for crews who install and work around buried infrastructure. Accurately record the position and depth of every asset you run into — no surveyor required. Whether you're laying conduit, crossing utilities, or building a new site, HAL keeps a precise, geo-referenced record of everything underground using GNSS technology. When a trench gets backfilled, that data doesn't disappear — it's there forever. — ACCURATE ASSET LOCATION — Capture the exact GPS position and depth of every buried asset as you install it. Know where your infrastructure is long after the trench is closed, even when the surface changes. — DEPTH INTELLIGENCE — HAL's Depth Intelligence automatically recalculates the depth of a buried asset when a new surface layer is added — no manual re-entry required. Always know the true depth, even years later. — AS-BUILT AUTOMATION — Generate ASCE-compliant as-built documentation with APWA color coding for all utility types, depth matrices, symbols, and photo evidence — automatically, with every scan. No drafting. No delays. — DETAILED DOCUMENTATION — Record every asset on your project. Attach photos and construction data to each point for complete traceability from installation to inspection. — PROJECTS DASHBOARD — Monitor your entire project from an interactive web-based map. See every asset, track field progress in real time, and share documentation with your team instantly. — AVOID COSTLY HITS AND DELAYS — Prevent accidental utility strikes before they happen. Reduce the risk of fines, emergency repairs, and project shutdowns with accurate, always-accessible underground records. BUILT FOR: • General contractors and civil construction crews • Utility and telecom installation teams • Public works departments and municipalities • Engineering firms requiring compliance documentation • Anyone who digs, installs, or manages buried infrastructure HAL pairs with GNSS receivers for centimeter-level accuracy and syncs with the HAL web dashboard for full project visibility. An active subscription is required. Build smarter. Locate faster.
