Sollertia Group of Engineers

What Sollertia Group of Engineers does

Sollertia Group of Engineers (legal entity Sollertia SA) is a privately-held Swiss civil engineering firm founded circa 1920 and headquartered in Monthey, with five technical and study offices across French-speaking Switzerland (Monthey, Martigny, Vevey, Aigle, Lausanne). The firm delivers professional engineering services through a multidisciplinary team of engineers, geomatics specialists, and draftspersons, organized around seven core disciplines: civil engineering and public works, conservation and renovation of art structures, construction of art structures, public building construction, industrial engineering, railway engineering, and drinking water services.

The company operates a professional services revenue model, quoting fees on a project-by-project basis with no public pricing. It serves both public project owners (communes, cantons, and the Swiss Confederation) and private clients (industrial operators and architects), generating work in areas such as bridges, hydraulic works, drinking water treatment, railway infrastructure, hydroelectric projects, schools, and sports facilities. Distribution is purely direct: Sollertia engages clients via its regional offices and through partnerships in multi-firm consortia on large public infrastructure programs — including the 2.2 billion CHF Rhône 3 river management initiative (2008–2030), a 130 million CHF hydroelectric project at Massongex/Bex, a 90 million CHF railway terminal at Monthey, a 22 million CHF covered trench at Clos-Donroux, and a 13 million CHF seismic dam reinforcement project with CNR.

Sollertia is independently owned with no disclosed external investors, parent entity, or subsidiaries. Revenue, headcount counts, and management identities are not publicly disclosed. The firm's marketing footprint is limited to its corporate website (sollertia.ch) and direct referrals; there is no evidence of patents, proprietary software products, AI/ML capabilities, or external funding rounds.
