Finally, a Map That Matches What's Actually Down There.
Walk a tunnel once and get a 3D model that replaces decades-old blueprints — built from sound and motion, not guesswork.
The blueprint says there's a 1.2-meter sewer main running north. You're standing in front of a 1.8-meter trunk that curves east into an undocumented junction. Every utility network has these ghosts — undocumented changes, wrong dimensions, missing branches. SonicQuilt captures the real geometry as you walk, using ambient acoustics and motion to quilt together a true 3D model of what's actually there. One walkthrough replaces weeks of traditional re-survey and gives your team a model they can trust.
Replace Outdated Blueprints in One Pass
Walk the route once and SonicQuilt builds an accurate 3D model — no laser stations, no return trips, no surveying crew.
Catch Undocumented Infrastructure
Sound-based profiling detects branches, junctions, and chambers that never made it onto the original plans.
Reduce Re-Survey Costs Dramatically
Cut traditional re-survey time and crew size by generating geometry from a single inspector's walkthrough.
GIS-Ready Output
Export geo-referenced models directly into GIS platforms, BIM software, or asset management systems.
