sizeless

AI-driven workflow for civil engineering—from smartphone video to compliant documentation.

Visit sizeless

sizeless is an AI-supported documentation workflow for civil engineering that captures open trenches and house connections from smartphone video and converts the recordings into precise 3D digital twins for GIS and CAD. The process replaces manual sketches and separate survey appointments, allowing trenches to be documented immediately after the video is taken.

Capture runs through the SiteScan app on iPhone Pro using a guided workflow without special hardware. Algorithms generate a high-resolution, centimeter-accurate 3D point cloud, which feeds into norm-compliant 2D CAD revision plans in DWG/DXF and 3D models of pipe runs including house entries for GIS integration. The workflow functions without GPS in basement areas and supports identification of joints and pipes for measurement.

The product is aimed at civil engineering, district heating, and house connection projects, handled by existing project teams rather than specialist surveyors. Data storage is in the EU, and the company states DSGVO compliance with ISO 27001 certification in progress. A demo can be booked; no plan or pricing details are given.
