The plus for people and the environment Grolimund + Partner is a specialist engineering firm with five locations and 40 years of experience.

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.

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.

Noise is one of the most significant burdens in the vicinity of railway lines. For local residents, it means restless nights and a reduced quality of life. For project managers, noise is a sensitive factor that influences the acceptance of a project and helps determine how smoothly approval procedures run. Anyone planning railway infrastructure today must not only measure noise, but understand it, assess it proactively and reduce it effectively. This is exactly where G+P comes in.
