A real plus for people and the environment

Grolimund + Partner AG – a cutting-edge “environmental engineering company”.

Sustainability was the driving force behind our thoughts and actions long before this concept became fashionable. After all, every construction project impacts the existing environmental fabric. Thanks to our extensive expertise and many years of experience, we carry out our work on the basis of environmental and economic principles and thus achieve a long-term benefit for those affected.

Specialist knowledge

A high degree of specialisation in the rapidly developing fields of environmental engineering, building physics and IT is the prerequisite for the highest level of competence in all technical and legal matters. Continuous training and further education of our employees is therefore important to us. We put a lot of effort into ensuring that they get the training and education they need.

Interdisciplinary cooperation

We work together in interdisciplinary project teams with partners from our extensive network.

Our services

You can rely on our experience and specialist knowledge at all levels of a project: from the initial concept to the operation of buildings and facilities. We offer you training courses, basic preparation, general and detailed analyses, consultations, concepts, measurements, planning, project development and expertise.

Our approach

Together with you, we define your goals and determine the services that you need. During implementation, we always follow the specific guidelines. We have a motivated team of employees and state-of-the-art tools and instruments. With five offices throughout Switzerland, we try to be close to our customers. Every order is supervised by a member of the Executive Board, which ensures quality and long-term continuity in order handling and the transfer of know-how.

Tyre/road noise

Our services include measurements to determine the acoustic quality of road surfaces, for example using the CPX trailer measurement method, as well as specific measurement methods and analyses for acoustic optimisation of road surfaces.

Building physics

Our expertise includes building and room acoustics as well as thermal building physics, building ecology and energy efficiency consultancy.


We specialise in developing environmental databases, noise calculation software, information systems and documentation – all tailored to the needs of our clients.

Research & development

We can count on an extensive national and international network in practice-oriented research in our key areas.

Environmental noise

We specialise in acoustic measurements and finding solutions to reduce noise emissions and vibrations from road traffic, railways, shooting ranges, commercial and industrial properties, building sites, etc.
