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.

«Thanks to G+P, I have the opportunity to develop my skills in a dynamic and friendly professional environment. The projects I'm involved in are varied and stimulating, offering the chance to make tangible improvements to the daily lives and quality of life of many people by protecting them from noise pollution.»

«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.»

«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.»

«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.»

«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.»

«There are good reasons why I have been working at G+P since 1996: I have always been able to familiarize myself with new areas, receive further training and help build innovative solutions. During this time, my children were born and grew up – the flexibility of G+P in terms of workload and working hours was and is invaluable. I love the working atmosphere, where you can bring in and implement your own ideas, even for new work processes.»

Nicole Freuler

Team

«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.»

David Karlicek

Team

«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.»

«The supportive working environment and pleasant cooperation at G+P allows me to fully contribute my strengths. A high degree of diversity in the tasks to be solved requires a great deal of flexibility, responsibility and inventiveness. Attributes that are valued and encouraged at G+P and that are needed to develop good solutions together.»

«Noise pollution reduces the quality of life of those who suffer from it. My goal is to reduce them as much as possible – G+P provides me with the means to do this. Street noise and shooting noise - I have been able to develop in these areas thanks to the skills acquired in a dynamic, friendly and stimulating working environment.»
