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.

«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.»

«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.»
