What Grolimund and Partner AG does

Grolimund + Partner AG (G+P) is a Swiss specialist engineering firm founded in 1984 that delivers consulting, measurement, and software services in environmental noise protection, road surface acoustics, building physics, and vibration analysis. The firm operates from five locations across Switzerland (Bern, Aarau, Zurich, Deitingen, Neuchâtel), serving cantonal and municipal road authorities, federal agencies such as BAFU and ASTRA, architects, property developers, construction companies, and transport operators. Headcount stands at approximately 75 employees, with 90% holding university degrees and a 35% female representation; annual sales are disclosed at CHF 10 million.

The company's technology stack centers on proprietary measurement and software systems, including a 3D texture photogrammetry scanner exceeding 3.5 million points per measurement, SonRoad18 noise modeling integration, CPX tire-road noise measurement (pioneered in Switzerland since 2008), and the VIBRA-1/VIBRA-2 vibration analysis suite. G+P sells three branded software products (DECIBASE, SLIP, QuietPave) and offers an AI-based advisory tool called Quietpave-check for optimal selection of low-noise road surfaces. The firm actively publishes at international acoustics conferences (InterNoise 2022, 2024) and leads the STEER consortium under CEDR with NOKIAN, BRRC, SINTEF, and VTI on improving EU tire noise labeling.

Revenue is generated through professional engineering services billed monthly with 30-day payment terms, supported by commercial liability insurance of CHF 10 million for personal injury and property damage. The business is partner-owned with no disclosed external funding rounds; Thomas Boss became CEO in January 2024 after a leadership transition, and the firm is led by partners including Erich Marti (CFO, HR). The company relocated its Bern headquarters to the VIDMARplus-Areal in December 2022 to support continued growth and celebrated its 40th anniversary in September 2024.

Direct peers

• Wölfel Engineering: German engineering firm specializing in vibrations, acoustics, and structural dynamics, including measurement systems and software. Directly comparable for VIBRA-style vibration analysis and rail/road traffic noise consulting.
• Norsonic AS: Norwegian manufacturer/integrator of acoustic measurement instruments and noise-monitoring solutions. Comparable for CPX-style field measurement equipment and road acoustics instrumentation that G+P uses and specifies.
• Lärmkontor GmbH: German specialist consultancy for environmental noise, traffic noise, and urban sound planning. Operates in the same regulatory and engineering niche as G+P's outdoor noise practice.
• ACCON GmbH: German engineering consultancy offering acoustics, building physics, vibration, and environmental measurement services. Direct competitor for building physics and measurement-driven projects.
• Graner + Partner Ingenieure: German engineering consultancy specializing in building physics, acoustics, and energy consulting. Comparable mix of building physics and acoustics consulting; serves similar building/construction industry clients.
• Müller-BBM Group: Germany-based engineering consultancy providing acoustic, building physics, and environmental services for buildings, transport, and industry. Closest scale-and-scope analog to G+P, with a similar mix of consulting, measurement, and software.

Emerging players

• SoundPLAN GmbH: German developer of noise-mapping and prediction software used by environmental consultants worldwide. Highly relevant as a software peer — G+P's DECIBASE and QuietPave play in the same noise-modeling category.
• DataKustik GmbH: German software vendor for noise mapping, sound propagation, and building acoustics. Comparable as a software peer addressing the same end-user base (consultants, authorities) that G+P sells DECIBASE/SLIP to.

Broad incumbents

• Hottinger Brüel & Kjær (HBK): Global measurement and analytics platform for sound, vibration, and acoustics. Provides broader instrumentation and software suites that intersect with G+P's measurement and modeling stack, but at much larger scale.

Others

• Empa (Swiss Federal Laboratories for Materials Science and Technology): Swiss federal research institute collaborating with G+P on PV-on-motorway acoustic assessment. Acts as an R&D partner and validation body rather than a direct competitor, but shapes the same Swiss standards landscape.
