Tracking road traffic noise

Tracking road traffic noise

Two low noise pavement mixtures on the same road, but which one performs better in the long term? In the Canton of Solothurn, G+P’s Pavement Acoustics team is supporting a test section with a comprehensive analysis programme. Initial findings show that anyone aiming to make the right decisions must look far beyond standard measurements.
Cool Pavements, Local Stone

Cool Pavements, Local Stone

Switzerland is getting hotter, especially in urban areas. We are currently completing a research project that shows: cool asphalt surfaces can be achieved using locally available Swiss aggregates while still meeting requirements for safety, durability, noise and cost effectiveness.
Homogeneous data for reliable noise protection

Homogeneous data for reliable noise protection

Monitoring road traffic noise is a complex task that requires detailed and reliable data. Whether for legal compliance, long-term strategies or the targeted planning of mitigation measures, the quality of decision-making depends directly on the quality of the data and the underlying models. In practice, this is often where the greatest challenges arise. Incomplete datasets, varying data quality and the large volume of available geodata complicate many projects. How can these challenges be addressed through the right combination of automation and professional expertise? The key lies in targeted data homogenisation and the semi-automated creation of comprehensive noise models, supported by the specialist expertise of engineers.

Grolimund + Partner creates added value in all areas of its offering.

We are leaders in our specialist areas of outdoor noise, road surface acoustics, building physics, software and research & development. We provide high-quality services and develop solutions that benefit people and the environment.

One year of communicating values

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 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!»

«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).»

«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.»

«At G+P, I can apply my expertise to a huge variety of projects, from architectural competitions to interior design - whether it's an assessment of the volumetrics or the proportion of glass in a giant superstructure or choosing the right curtain fabric for the acoustics in a living room. I find the exchange with customers and other construction experts enriching and instructive. I particularly appreciate the friendly atmosphere at G+P, the uncomplicated exchange and flexible organization.»
