3D texture measurements - visual method for determining the surface properties of road pavements

3D texture measurements - visual method for determining the surface properties of road pavements

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.

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.

Complex noise situation – G+P measures train noise from Lausanne marshalling yard

Complex noise situation – G+P measures train noise from Lausanne marshalling yard

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.

«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.»

«Through my work in road surface acoustics at G+P, I am committed to making road noise an issue and reducing it wherever possible. The horizon-expanding measurements on Swiss roads, as well as the evaluations in the office surrounded by a great team, make for a great change. The flexible part-time workload gives me the opportunity to balance my activities as a musician and the work at G+P, for which I am very grateful.»
