Recycling low-noise SDA asphalt

Over the past years, several hundred kilometres of highly effective low-noise SDA 4 road surfaces have been constructed across Switzerland. Many of these sections are now approaching an age at which replacement will soon be required. One aspect has so far received little attention: these specialised surfaces cannot be recycled as easily as conventional road materials. This issue will become increasingly relevant in the coming years. By 2030, more than 200,000 tonnes of SDA material are expected to arise and will need to be reused in a technically sound manner.

3D City Models as a Tool for Noise Control

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.

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 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.»

«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.»

«As a mother of two children, I am grateful to be able to work in such a diverse and dynamic environment, which also inspires me every day and is so family-friendly. With a part-time workload, very flexible working hours and the possibility of a home office, G+P is very accommodating to my family management.»

«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).»

«As part of the pavement acoustics team, I carry out acoustic measurements throughout Switzerland and evaluate the measurement results in the office. In doing so, I particularly appreciate the thematic reference to my geography studies. In addition, unlike many of my fellow students, the combination of my professional activities and my studies was made extremely easy for me by the possibility of flexible working hours, for which I am extremely grateful.»

«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!»

«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!»

«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.»

«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.»

«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.»
