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.

«The welcome that G+P gave me when I arrived at 2022 was overwhelming. I immediately felt at home in the company. The projects are varied and very interesting and the people at G+P are always willing to collaborate and help, which is the strength of our team.»

«Every new order is an exciting challenge. I enjoy satisfying our customers' needs with our high quality standards. Regardless of whether it is a short consultation on site or a large project with complex measurements and modeling - even with more than 15 years of experience in acoustics, no project is the same and the motivation is constantly high!»

«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.»

«Working as a noise protection engineer has opened my eyes to the various impacts of noise on people's health. At G+P, I have the opportunity to work in a young and dynamic company, and I can take part in the fight against noise pollution, actively contributing to the well-being of the Swiss population through the realisation of varied and exciting projects.»

«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).»
