sizeless
Product

From video to CAD plan.

Built for the crews that open the trenches: district heating, water, power, gas and fiber.

The problem

Measuring what lies where still happens by hand.

For contractors
  • Weeks pass between completion and invoicing, and cash flow suffers.
  • Site managers document late and reluctantly, so data arrives incomplete.
  • Manual measurements are error-prone and don't hold up in disputes.
For utilities
  • As-built plans take months to arrive, sometimes up to a year.
  • Surveyor, engineering office and rework in the back office: every handoff adds cost.
  • Contractor invoices can't be checked against independent data.
The solution

A phone video delivers survey-grade 3D records.

No hardware. No on-site expert. No back office.

  1. Capture

    The crew or site manager films the open trench in under ten minutes, then backfills right away.

  2. Process

    sizeless processes the video fully automatically. No specialist needed.

  3. Deliver

    Within 72 hours, all data is ready for planning, records and invoicing.

  • 01

    Invoice sooner

    Quantities ready for your invoice within days.

  • 02

    Less staff on site

    No surveyor, no specialist. Every site manager can do it, and the process scales with your order volume.

  • 03

    Complete 3D evidence

    Before backfilling: third-party lines, depths and dimensions.

  • Billing-ready documentation within days, VOB-compliant: excavation volume, laying lengths and isometrics, straight into your invoice.

Formats

Every document the trench needs. From one video.

In the formats your planners, your GIS and your accounting already use. More formats such as Interlis will follow.

3D reconstruction of an open trench with two district heating pipes

Centimeter-accurate point cloud and mesh of the open trench, including house entries and third-party lines. The objective basis for every drawing and every quantity that follows.

Technology

We turn smartphone videos into survey-grade 3D models.

  • Our own SLAM

    Survey-grade 3D from a single phone video, no extra hardware. A decade of research at ETH Zurich.

  • Semantic layer

    Recognizes type, brand, material and connections.

    Recognition
  • Conversational AI

    The crew's spoken notes, captured in the scan.
