Who are our 3D surveys for?

Architects

Reliable as-built drawings before you design the renovation, instead of archive plans that no longer match the building.

Example: listed building in Hérémence (VS), ArchiCAD model and DWG drawings.

Surveys for architecture →

MEP engineers and BIM managers

Existing installations surveyed as they are, then modelled at the level of detail your project phase requires (LOD 400–500).

Example: school complex in Collonge (GE), architectural and HVAC BIM model.

MEP surveys and Scan to BIM →

Property managers and building owners

Up-to-date drawings of your buildings, for day-to-day management as well as for planning works.

Example: group of listed buildings in Corsier (GE), Revit model and site plan.

Surveys for real estate →

General contractors

The existing site surveyed before work starts: condition of neighbouring structures, quantities and volumes for accurate pricing.

Example: building under construction in Gstaad, 3D model to check progress and streamline orders.

Surveys for construction →

Detailed Point Clouds in LGXS, E57, RCP formats

Leica RTC360 laser scanner on a survey site

The device (RTC 360 from Leica in our case) using LIDAR technology, captures 2 million points per second at each setup, gradually creating a point cloud of billions of points. Every point practically has coordinates. At the same time, 360° photos are captured to provide color insights.

For a 1,000 m2 building for example, we might need around 200 setups and we expect a point cloud of 2.5 billion points.

BIM model produced from a 3D point cloud

Advanced software algorithms, combined with user expertise, transform the point clouds into a precise and well-cleaned 3D model, free of reflections and other unnecessary objects.

Subsequently, depending on the desired deliverables, further software is applied to create: CAD plans (DWG, ArchiCad and REVIT), 3D BIM models, ortho-images, Virtual Reality, visualization of buildings in real time, or even digital twins.
