The plus for people and the environment Grolimund + Partner is a specialist engineering firm with five locations and over 30 years of experience.

Low-noise road pavements are used as effective noise abatement measures in Switzerland. To determine the actual effect of low-noise road surfaces, G+P uses numerous measurement methods. While the most common measurement methods record the properties of road pavements acoustically (e.g. with microphones), 3D texture measurements can be used to measure and assess the visual properties of road pavements that are relevant for noise generation. G+P has been carrying out such 3D texture measurements with its own photogrammetry scanner since 2022.

Today, the climatic and acoustic requirements of modern office landscapes are crucial for the well-being and productivity of employees. A pleasant room temperature, good air quality, adequate lighting, the attenuation of noise as well as possibilities for retreat and flexible workplaces are important aspects for creating an optimal working environment. As an engineering firm for building physics and acoustics, it was important to us to optimally implement these diverse requirements in our new office premises on Waldeggstrasse in Liebefeld-Bern. In this way, we also want to be an attractive employer for our valued employees.

Noise and exceedances of permissible limits are highly relevant issues of great importance, especially when it comes to public health. In this context, the analysis of noise generated by the installation of outdoor heat pumps (HPs) in densely populated neighbourhoods is crucial. Fundamental questions arise such as "If all homeowners decide to install a heat pump, is there not a risk of exceeding the permissible limits in the neighbourhood?". Expertise is needed to answer these questions. G+P, an expert in noise protection, is your ideal partner.

We are very pleased to announce that our branch in Bern has moved to the VIDMARplus area in Liebefeld-Bern on December 19, 2022.

Does the planned new building require a noise assessment? Are the noise protection measures already in place still sufficient? Will the noise limits still be complied with in ten years' time if traffic continues to increase? With the DECIBASE web application you have fast, intuitive access to noise data along roads or railway lines to answer these questions.

Lausanne-Triage station is the most important marshalling yard in western Switzerland. More than 60 km of tracks have been laid since the 1960s. Braking, shunting, impacts and the squeaking of wheels on the tracks are loud and disturb the residents despite the noise reduction measures already taken. G+P was able to measure this noise and identify possible improvements.
