BIM model of a hotel in St. Moritz


From scan to BIM on the fly – HMQ scans luxury hotel in St. Moritz

The Hotel Sonne in St. Moritz is a popular destination for skiing and Welness vacationers. To prepare the hotel for the future, HMQ AG was commissioned to generate a comprehensive 3D building model of all interior spaces and the exterior facade. The 3D point cloud data was required for further processing in Graphisoft Archicad to create a complete BIM model.

Right from the start, the project included a major challenge: the acquisition of the hotel with laser scanners from FARO had to take place during the peak winter season and also during ongoing guest operations. The entire building therefore had to be captured as quickly as possible and without major disruption to guests. In the interior, a floor area of 1,100 m² had to be surveyed, distributed over three floors and a building height of approx. 10 meters. Outside, the work was no easier. The snow lying at the time of the project, which is why vacationers primarily traveled to St. Moritz, made the scans of the facade difficult.

HMQ, however, managed all challenges and had a huge amount of point cloud data from around 500 scans after only 72 hours. HMQ has been using Archicad 21 software to create BIM models for some time. To be able to use the point cloud data for processing in Archicad, HMQ uses PointCab Origins. More specifically, use the 4BIMm plugin, which allows the point clouds to be analyzed and the information seamlessly transferred into ArchiCAD. This reduced time for HMQ and, consequently, project costs. Putting all this together, the result was a relaxed project process for everyone involved. This can only be beneficial for a vacation hotel.

The basis for this is the uniquely fast processing of the most extensive point clouds in PointCab Origins. Ease of use was the main focus when Christian Vetsch, Managing Director at HMQ together with his team decided to use PointCab Origins three years ago. The great compatibility with all scanner types and makes made the decision even easier for HMQ.

“We chose PointCab Origins because the software is easy and intuitive to use and is constantly being developed,” says Christian Vetsch. If you ask HMQ employees, they also appreciate the uncomplicated proximity to PointCab support.
