3D City Models as a Tool for Noise Control

How loud are our cities – today and in the future? Using the example of the city of Uster, G+P shows how traffic noise can be made visible in realistic 3D city models. These detailed virtual representations of the real environment provide a solid basis for planning, communication and targeted noise mitigation.

Digitalising Road Management: Glarus Leads the Way

Many municipalities lack reliable data on the condition of their road networks. The municipality of Glarus is changing that. Since March 2025, it has been using vialytics – a system that automatically assesses road conditions using a smartphone camera and artificial intelligence. As the exclusive Swiss partner of vialytics, Grolimund + Partner AG supported the municipality in implementing the technology and laid the foundation for modern, data-driven road management.

One year of communicating values

In January 2024, as "The New Boss", I explained in a video statement what is important to us and to me at G+P. After almost a year as the new CEO, it's time for a little look back. Our values take centre stage. Values are a key success factor, especially for SMEs like us.

«On the pulse of time in times of climate change – this makes the work at G+P both interesting and diverse. In addition, a very motivated team of well-trained specialists who complement each other very well and who bring the current state of knowledge of building physics into practice. The whole thing is rounded off by a really good team spirit and progressive boundary conditions, which is why I feel very comfortable here.»

«As „Boss“ of G+P, my mission is to work with our talented team to develop sustainable and innovative solutions that support our clients in their projects and at the same time have a positive impact on our environment. It gives me great pleasure to work in such a dedicated team and to drive forward our vision of a quieter and more liveable world together.»

«Noisy industrial plants are often located on the roofs of high buildings. For measurement campaigns, I therefore regularly find myself at lofty heights and can enjoy the panorama from unique locations. The combination of field work (with foresight), the analytical and editorial work in the office and the variety of noise sources and projects make the work in the outdoor noise team at Grolimund+Partner very varied.»

«I have been with G+P AG for over 20 years. I appreciate the good cooperation and the lively exchange of information in the team. I can contribute my extensive practical construction knowledge and experience to the team, on the construction sites, when problems arise or in the event of construction damage. The knowledge gained from construction damage is passed on as an ongoing learning process within the team. As of October 2022, I will be partially retired and will continue to work at G+P AG with a workload of 40%. I spend a lot of time in the mountains (climbing, ski touring) as compensation.»

«I have been working for G+P on a part-time basis for more than 20 years, and thanks to G+P's great flexibility I have been able to combine family and career wonderfully. I experience G+P as a dynamic team and a generous employer in all respects, from the coffee and croissants on offer, the great employee events, to the generous BVG insurance benefits. I am proud to work for G+P.»

«I find it exciting and enriching to exchange ideas across disciplines in the G+P team. Everyone contributes their own experience and expertise, whether it's during a project meeting, a coffee break or an after-work beer. We always come up with creative and goal-oriented solutions for our customers, even for particularly challenging problems.»

«At G+P, I appreciate the good teamwork. What motivates me in working on the projects is that we contribute to a more comfortable use of the buildings. Comfort is related to global warming (summer heat insulation) and the ever-increasing density and its noise development in the building itself (sound insulation and room acoustics).»

«Working at G+P means working with diverse teams made up of people from different backgrounds, which provides the opportunity to explore new perspectives and approaches. The willingness to learn something new is always present and contributes to increased motivation. The activities at G+P are very diverse and often lead to interesting collaborations, sometimes reflecting personal passions. Self-organisation is a key element that offers great freedom and enables a good work-life balance. We are always on the lookout for new energy solutions, both in the area of sustainability and in the other activities we are involved in. The variety of projects is exciting and ranges from small detached houses to large buildings, often located in protected zones. We work on projects all over Switzerland, sometimes switching from German to French to Italian in the blink of an eye. In short, working at G+P means never being bored!»

«At G+P, I appreciate the broad and exciting field of activity at the interface between outdoor noise and software development. Thanks to further training supported by G+P, I can specifically take on new challenges in GIS and data modeling. In addition, the flexible working hours model allows a compatibility with the family.»
