FRIEDLIPARTNER

What FRIEDLIPARTNER does

FRIEDLIPARTNER AG is a Swiss environmental and geotechnical consulting firm founded in 1974 by Peter Friedli, headquartered in Zürich-Oerlikon and operating four branch offices (Solothurn, Lenzburg, Buchrain, Winterthur) across German-speaking Switzerland with approximately 50 specialists. Its service portfolio is organized around eight domains: Baugrund (subsoil), Geotechnik-Spezialtiefbau (specialized civil engineering), Geologie-Hydrogeologie, Altlasten (contaminated-site investigation and remediation), Bodenschutz-Umwelt (soil protection and environment), Asbest-Schadstoffe (asbestos and hazardous materials), Bauerneuerung-Nachhaltigkeit (building renewal and sustainability), and Abfälle-Ressourcen (waste and resources). The firm runs its own in-house drilling capability and supports projects with Leapfrog 3D geological modelling, Plaxis finite-element geotechnical analysis, and a proprietary regulatory reference product, GRENZWERTE.swiss, that is also sold as a standalone subscription.

The customer base is split between Swiss public-sector authorities — federal offices, cantonal environmental and construction agencies, and municipal building-permit authorities — and private-sector developers, contractors, and real-estate owners. Named private clients include Losinger Marazzi and real-estate firms; public mandates are typically procured through cantonal and municipal tender processes. The firm's pricing model is professional-services project-based fees (often regulated under standard Swiss public-procurement fee scales), supplemented by subscription revenue from GRENZWERTE.swiss. The company is privately held, does not disclose financials, and historically has not taken institutional capital, making it a classic mid-sized owner-operated specialty consultancy.

The most material recent event is the death of founder Peter Friedli on 1 May 2026, which creates a generational succession question for a firm whose brand identity has been closely associated with the founder. Operationally, the firm has executed a clear multi-node expansion (Lenzburg 2016, Buchrain 2019, Winterthur 2021), added the building-renewal/sustainability division (2017), renewed its management (2019), and is in the early stages of digitizing its reporting archive through internal AI tooling. No customer concentration is disclosed and no revenue is published.
