What Grisoni-zaugg S.a. does

Groupe Grisoni (legally Grisoni-Zaugg SA) is a privately held Swiss construction group founded in 1946 and headquartered in Vuadens, Fribourg canton. Operating primarily in French-speaking Western Switzerland (Romandy), the group delivers a broad portfolio of construction services spanning civil engineering, building construction, special works, geothermal and hydrogeological drilling, demolition and asbestos abatement, railway infrastructure, wood construction, and turnkey general contracting. Its customer base is split between public-sector clients (municipalities, cantons, federal entities such as CFF Immobilier, Armasuisse, HUG, and the cities of Bulle, Vevey, and Sainte-Croix) and large private enterprises (Nestlé, Rolex, AXA Switzerland, Coop, Nash Hotels, Mobilière Asset Management, Groupe Gruyère Energie).

The group executes work through seven wholly-owned specialized subsidiaries — ISR Injectobohr SA (foundation engineering and secant piling), Fracheboud SA (controlled demolition and asbestos removal), Augsburger Géothermie SA (medium-depth geothermal drilling up to 800m), Dougoud Construction Bois SA and Lanthmann Constructions Bois Sàrl (wood construction and timber framing), and Casella Travaux Acrobatiques Sàrl (acrobatic/special-access works) — plus a partial acquisition of Maurice Moura & Fils SA (material recycling, October 2024). This subsidiary architecture enables the group to self-perform specialized trades in-house on consortium projects, supporting credentials such as Minergie-P, Bois Suisse, and the 2024 Prix Lignum Bronze won for the Passerelle des Buissons pedestrian bridge.

Revenue is generated through project-based professional services contracts, won primarily via competitive public-sector tendering and direct private negotiation. Pricing is project-specific and not publicly disclosed; commercial moat rests on regional reputation, multi-trade in-house capability, and demonstrated execution on complex urban and infrastructure projects across Vaud, Fribourg, Geneva, Neuchâtel, and Valais. Headcount is reported in the 1,001–5,000 range; revenue figures are not publicly disclosed. The group is led by Directeur général Louis Risse, and ownership appears to be private/family-controlled with no external investor or public-market disclosures in the source material.
