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.

«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.»

«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 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!»

«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.»

«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.»
