3D scanning and modelling by drone in Switzerland: point clouds for engineers and architects

Drone 3D scanning combines high-resolution aerial photogrammetry with precise digital processing to produce faithful 3D surveys of buildings and infrastructure. In Switzerland it is transforming the work of architects, engineers and design offices by greatly reducing on-site survey time.

What is drone 3D scanning?

The drone acts as a data-capture vehicle: its high-resolution cameras take hundreds of photos from different angles, which photogrammetry software turns into a cleaned, georeferenced 3D point cloud. That point cloud is a reliable base for your own BIM modelling, CAD plans or technical analysis.

Result: a complete, metric survey of a building in a few hours, where traditional methods take several days on site.

Plans and prices

Three plans adapted to the complexity of your project:

PlanPriceBest for
Scan EssentialCHF 690First assessment, preliminary plan, light inspection
Scan ProCHF 1,450Technical plans, preliminary designs, study files
Scan ProjectCHF 2,100Demanding projects, ±0.5–2 cm accuracy, georeferenced data

Files are delivered within 3 days (Essential), 4 days (Pro) or 5 days (Project). All CAD/BIM formats are included according to the plan.

Accuracy and performance

  • Metric accuracy: 5–10 cm as standard, ±2–3 cm with Scan Pro
  • Scan Project accuracy: ±0.5–2 cm with ground control points
  • Image resolution: up to 50 MP
  • Area covered: from a few hundred m² to several hectares per mission

Use cases in French-speaking Switzerland

Renovation and extension upwards

Before any renovation or added storey, an accurate 3D survey of the existing building is essential. Drone scanning avoids sizing errors and eases coordination with tradespeople.

Site control and acceptance

Compare what has been built with the execution plans: the scan reveals dimensional deviations, misalignments or non-conformities before acceptance of the works.

Heritage documentation

Digital inventory of historic buildings, documentation for cantonal heritage commissions, or 3D models for promotion.

Missing plans

Many Swiss buildings predate computers and have no digital plans. Drone scanning produces as-built DWG plans in a few hours, with the raw point cloud available on top.
