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.

«For me, it is important to work in a software team that is both competent and constructive. At G+P, I can do this by working for a company that helps people improve their lives.»

«Working with and for different clients allows me to gain insight into a wide variety of fields of activity. At G+P itself, we work in interdisciplinary teams across the various specialist areas to find solutions. The focus is often on the goal of providing more peace and quiet for the population. I also really appreciate the fact that I can work in several branches and at home, and that the PC-heavy work is always broken up by measurement work outside with the CPX drivers, alone and with office colleagues.»

«What I appreciate most about G+P is the wide range of building physics topics that we are able to deal with on a daily basis as part of an outstanding team. It is a personal concern of mine to support and accompany our customers every day on their way to greater energy efficiency and sustainability. In this way, I can make a personal contribution to a ‘greener’ world of tomorrow, both for the general public and for my two small children, for whom I have plenty of time thanks to my ‘daddy day’ and 80% workload.»

«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.»

«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.»

Thanks to further training supported by G+P, I can specifically take on new challenges in GIS and data modeling.
