Benefits for Network Operators

From video to CAD plan - for civil engineering, district heating, and house connections.

Accelerate Construction & Billing

Trenches are backfilled immediately after the video - no waiting for separate surveying appointments. Complete documentation is available weeks earlier, enabling faster billing and cash flow.

72h docsDWG / DXFInstant backfill

Quality & Audit-Proof Documentation

Continuous 3D evidence including third-party utilities and house entries (works without GPS in basement areas). Eliminates manual sketches and data silos - construction errors can be identified before backfilling.

Process Autonomy

Technicians document house connections independently via smartphone. Existing internal or external teams can handle a higher project volume through efficient workflows.

From Video Directly to CAD Plan

AI-powered workflow for civil engineering - from smartphone video to compliant revision documentation

Step 01
Trench Capture
Standardized capture via iPhone Pro directly at the excavation - no special hardware, no extra appointments. Carried out by the existing project team.
Step 02
3D Point Cloud
Algorithms developed at ETH Zurich generate a high-resolution 3D point cloud of the open trench - centimeter-accurate.
Step 03
2D CAD As-Built Plan
Industry-standard as-built plans (DWG/DXF) for revision documentation. Couplings and pipes are quickly identified - measurement extraction simplified.
Step 04
3D Model & GIS
Digital twins of the pipe route including house entries. Seamless integration into GIS systems for future-proof planning and maintenance.

Outputs

One capture. Every output.

A single smartphone scan produces every deliverable your team already works with — ready to drop into existing tools.

Centimeter-accurate point cloud

High-resolution 3D reconstruction of the scanned space. Objective basis for earthwork volumes, dimensions, and audit trails.

On-site

Scan with SiteScan — the Sizeless iPhone app

Your field team captures properties, trenches, and technical rooms in minutes using a guided iPhone Pro workflow. No extra hardware, no specialist training.
