What B. Ott et C. Uldry does

B. Ott et C. Uldry SARL is a Geneva-based civil engineering consultancy founded in 1979 by Fernando Herrera and taken over in 1998 by its current principals, Bernard Ott (EPFL-trained, holder of a doctorate in technical sciences, SIA AGI certified) and Claude Uldry (ETS-trained). The firm operates as a SARL (private limited liability company) under Swiss law, is privately held with no external investors, and is headquartered in Thônex within the Canton of Geneva. Its core offering is full-lifecycle project management as lead mandator, spanning conception, design, financial planning, execution oversight, and delivery, complemented by feasibility studies, expert consulting, and quality control missions.

The firm delivers three service lines: Bâtiment (residential, commercial, industrial, educational buildings, elevations and transformations, exposed concrete); Espace public (public space infrastructure including collectors, roads, and squares); and Génie civil (railway construction and parking infrastructure). Its technical competencies span reinforced and prestressed concrete, steel, wood and composite construction, prefabricated structures, and special foundations, including complex techniques such as underwater parking, seismic retrofitting, and Minergie-certified sustainable construction. The team comprises approximately 15 civil engineers, draftspersons, and administrative staff organized under two Ingénieurs dirigeants, three Directors, and a Head of Drawing Office.

The business model is professional services, project-based, with revenue generated through direct enterprise-field-sales engagement of public-sector clients (Swiss Federal Railways, Canton of Geneva, Ville de Genève, Geneva International Airport) and private-sector clients (housing cooperatives, hospitality groups, real estate developers, industrial operators). Cumulative documented project value exceeds CHF 400 million across the firm's history. The firm markets itself primarily through its website, professional networks, and the visibility of its award-winning project portfolio, with no disclosed pricing transparency.
