How loud are our cities – today and in the future? Using the example of the city of Uster, G+P shows how traffic noise can be made visible in realistic 3D city models. These detailed virtual representations of the real environment provide a solid basis for planning, communication and targeted noise mitigation.

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.

«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.»

«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.»

«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.»

«I am fortunate to work with people who share the core values of ethics, trust and listening, and who are committed to providing quality service for the benefit of projects that matter to people. My motivation is to promote and develop this culture.»

«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).»

«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.»

«Working at G+P means working with diverse teams made up of people from different backgrounds, which provides the opportunity to explore new perspectives and approaches. The willingness to learn something new is always present and contributes to increased motivation. The activities at G+P are very diverse and often lead to interesting collaborations, sometimes reflecting personal passions. Self-organisation is a key element that offers great freedom and enables a good work-life balance. We are always on the lookout for new energy solutions, both in the area of sustainability and in the other activities we are involved in. The variety of projects is exciting and ranges from small detached houses to large buildings, often located in protected zones. We work on projects all over Switzerland, sometimes switching from German to French to Italian in the blink of an eye. In short, working at G+P means never being bored!»

«Over the past 30 years, G+P has enabled me to realize all of my professional visions, wishes and ideas and to have a challenging, exciting and successful career. As an entrepreneur, I would like to offer this creative freedom and these development opportunities to as many young, committed and motivated employees in our team as possible who want to seize this opportunity.»

Toni Ziegler

«What I appreciate about G+P is the extremely broad field of activity, which ranges from normal project work to conference participation and international research collaboration. Likewise, I think it's great that the coffee break can be actively used to compare current conditions in the mountains, which creates a welcome balance between work and free time.»

Felix Schlatter

Team

«At G+P, I can ideally combine my passion for environmental and sustainability topics with my professional skills from the finance & HR world. In the meantime, it's always a pleasure to work alongside an enthusiastic and motivated team every day, offering assistance and support to colleagues from different departments.»
