Creating an exact BIM model of a hotel in St. Moritz
HMQ AG scanned the Hotel Sonne in the luxury resort of St. Moritz and created a comprehensive BIM model from it – during the winter high season.
St. Moritz in the Swiss canton of Graubünden (Grisons) has always stood for exclusive lifestyle, winter sports, elegance and style. The hotel Sonne in St. Moritz is therefore a popular destination for holidaymakers who have certain expectations of their accommodation.
In order to equip the hotel for the future, HMQ AG, also based in the canton of Graubünden
(Grisons), was commissioned to generate a comprehensive three-dimensional building model of all interiors as well as of the exterior facade. The 3D point cloud data was needed for further processing in Graphisoft ArchiCAD to generate a complete BIM model.
Right from the start, the project posed a major challenge: the hotel had to be captured with FARO laser scanners during the main winter season and also during ongoing guest operations.
The entire building had to be captured as quickly as possible and without major disruption to ongoing operations and, of course, as detailed as possible. In detail, this means that a floor area of 1,100 m², distributed over three floors and a building height of approx. 10 metres, had to be recorded in the interior.
In the outdoor area, the work was not any easier either. The snow lying at the time of the project, which is why the holidaymakers primarily travelled to St. Moritz, made the scans of the façade more difficult to capture.

The interior of the hotel was also scanned by laser scanner and transferred into the BIM model.
HMQ, however, managed all the challenges and, after 72 hours of focused work, already had a huge amount of point cloud data from around 500 scans in its luggage.
HMQ has been using the software ArchiCAD 21 for a long time to create BIM models of buildings. HMQ uses also PointCab software to defuse the bottleneck of point cloud processing as effectively as possible, especially with such extensive data. To be more precise, HMQ uses the PointCab 4BIMm version, with which the point clouds can be evaluated on the one hand, at the same time the information can also be seamlessly transferred into ArchiCAD. This reduced HMQ’s time expenditure and consequently its project costs.
The uniquely fast processing of the most extensive point clouds in PointCab is the core of it all. The simplicity of use was key when Christian Vetsch, Managing Director at HMQ, and his employees decided in favour of PointCab three years ago. PointCab´s compatibility with different scanner types and makes made Mr. Vetsch’s decision even easier.
“We chose PointCab because the software is easy and intuitive to use and is constantly being further developed,” says Christian Vetsch.
Asking the HMQ employees, they appreciate the uncomplicated proximity to the PointCab support team in addition to the points mentioned above.
Summarising all this, HMQ and everyone involved were relaxed about the course of the project than previously imagined. All this that can only be beneficial for a holiday hotel serving its guests in a professional manner.
A software that is easy and intuitive to use and is constantly being further developed.
