Triform EA SA

What Triform EA SA does

Triform EA SA is a Fribourg, Switzerland-based environmental and acoustic engineering consultancy employing approximately nine multidisciplinary specialists. The firm originated as part of Triform AG (founded in 1991 by Markus Bapst and Peter Lehmann) and became an independent entity in 2024 following a corporate split that created a parallel water-services firm (Triform SA); Nadia Benyahia leads the new entity as Direction (CEO), with Markus Bapst serving as advisor. The firm delivers project-based professional consulting across nine domains: environmental impact assessments, building and room acoustics, environmental noise studies, soil protection and pedology, contaminated site investigation and remediation, building pollutant diagnostics (asbestos, PAH, PCB, heavy metals), chemical risk assessment under OPAM/StFV, and natural habitat protection.

The service portfolio is supported by industry-standard specialized tooling rather than proprietary IP: CADNA/A for 3D environmental noise modeling, EASE for room acoustics, SonRail for SIA 181 railway noise, FAL 24+ soil survey standards, portable XRF analyzers for on-site heavy-metal detection, and QGIS/ArcGIS/Soildat for environmental mapping. These tools are deployed by ETH/EPFL-trained engineers, biologists, chemists, and physicists, many of whom hold Swiss sector credentials such as the BGS soil-protection label and VABS asbestos-consultant membership.

Commercially, Triform EA generates revenue from professional-services fees quoted per project. GTM is sales-led and relationship-driven, with engagements sourced via professional reputation, client referrals, and participation in public procurement tenders. Customers span Swiss federal entities (Armasuisse, BBL), cantonal and municipal administrations (Gemeinde Gurmels, Commune de Misery-Courtion, Gemeinde Aigle), public-transport infrastructure (TPF INFRA), residential and commercial developers (Bulliard Immobilier, L'Habitat de la Prillaz, Urban Project SA), industrial operators (B+T Engineering, Ideal Chimic), and a banking-sector building-renovation client (Banque cantonale de Fribourg). Operations span at least five cantons — Fribourg, Vaud, Bern, Valais, and Geneva — with the head office at Bd de Pérolles 55, 1700 Fribourg.
