Digitalising Road Management: Glarus Leads the Way

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.

Grolimund + Partner creates added value in all areas of its offering.

We are leaders in our specialist areas of outdoor noise, road surface acoustics, building physics, software and research & development. We provide high-quality services and develop solutions that benefit people and the environment.

One year of communicating values

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.

«As a mother of two small children, G+P offers me the opportunity to take on responsibility and manage exciting and challenging projects despite a relatively small part-time workload, and to be able to do this very flexibly, which makes it easy to combine with everyday family life. I was also able to meet my wonderful husband at G+P.»

«With the CPX measurement system, we are on the road all over Switzerland measuring the acoustic effect of road surfaces. During these measurements, I discovered many beautiful places throughout Switzerland and was inspired by the different landscapes: sunsets in the canton of Fribourg, summer days on Lake Maggiore or winding drives up unknown mountain passes. The perfect balance to the daily office routine.»

«At G+P, I can apply my expertise to a huge variety of projects, from architectural competitions to interior design - whether it's an assessment of the volumetrics or the proportion of glass in a giant superstructure or choosing the right curtain fabric for the acoustics in a living room. I find the exchange with customers and other construction experts enriching and instructive. I particularly appreciate the friendly atmosphere at G+P, the uncomplicated exchange and flexible organization.»

«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.»
