sizeless
Request a demo

No surveyor. No special hardware. No weeks of drawing work.

Your crew films the open trench. Within 72 hours you have the 3D model, the drawings and the quantities for billing.

Capture.

One person, one smartphone, about ten minutes per trench.

Detect.

Every pipe in the scan is found and labeled with type, diameter, material and position. The crew can add voice notes on the spot.

Model.

sizeless builds a centimeter-accurate 3D model of the trench, its pipes and fittings.

Integrate.

As-built drawings, quantities and GIS data flow straight into your billing and network map.

The problem

Maps went digital. Measuring is still done manually.

For contractors
  • Measuring needs a specialist. Every step means coordination, waiting and another site visit.
  • No measurements, no invoice. You pre-finance finished work for months.
  • Photos don’t prove how deep you dug. Every claim for extra work means months of back-and-forth.
For utilities
  • Contractor, surveyor, engineering firm. Every handoff adds cost and errors.
  • As-built drawings arrive months late. Your GIS is never up to date.
  • Not measured before backfill? Then it’s lost for decades.
What measuring looks like today
  • GNSS rover
  • Total station
  • Measuring wheel
  • Folding rule
  • Tape
  • Laser meter
The solution

Turn a phone video into survey-grade 3D records.

One person films the trench. sizeless automates the rest.

  1. Capture

Technology

Built on a decade of robotics and physics research. 

  • Proprietary SLAM engine

    Survey-grade 3D from a single recording, no extra hardware.

    3D reconstruction
  • Semantic layer

    Recognizes type, material and connections of every pipe.

    Recognition
  • Conversational AI

    Voice notes from the crew are linked to the scan.

All it takes is a smartphone: capture the site as-is. No equipment, no scheduling with a surveyor.

Vision

For crews today. For humanoid robots tomorrow.

Construction productivity has barely moved in decades. Here is how we want to change that.
