sizeless

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.

Capture.

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

Recognize.

Every pipe found and labeled: type, diameter, material, position. Plus what the crew said on site.

Plan.

The 3D record of the trench, as point cloud, mesh and BIM model (IFC), becomes your as-built plan.

Integrate.

Contractors get quantities, invoicing data, as-built drawings and isometrics. Utilities get GIS-ready network data and verified quantities.

The problem

The maps went digital. Measuring what lies where still happens by hand.

For contractors
  • Measuring isn't done by the crew on the ground, so every step means coordination and another site visit.
  • Invoicing waits months for documentation, and cash flow suffers.
  • Manual measurements don't hold up in disputes, so payments get cut.
For utilities
  • Every handoff between contractor, surveyor and engineering office adds cost and errors.
  • As-built plans arrive months late, so your GIS is never up to date.
  • Once the trench is closed, whatever wasn't measured is lost for decades.
What measuring looks like today
  • GNSS rover
  • Total station
  • Measuring wheel
  • Folding rule
  • Tape
  • Laser meter
The solution

A phone video delivers survey-grade 3D records.

Capture, recognize, plan, integrate: one person films the trench, sizeless does the rest.

  1. Capture

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

  2. Recognize

  4. Integrate

    Contractors get quantities, invoicing data, as-built drawings and isometrics. Utilities get GIS-ready network data and verified quantities.

All it takes is a smartphone: capture the status whenever you're on site. No equipment, no scheduling with a surveyor.

Vision

For crews today. For humanoid robots tomorrow.

Construction is the one industry that stopped getting more productive. Here is how we want to change that.
