What Ulaga Weiss Ag does

Ulaga Weiss AG is a Swiss structural engineering consultancy (Dipl. Bauingenieure ETH SIA USIC) founded in 2009 by Tomaz Ulaga and Dominik Weiss and headquartered at Hutgasse 1 in Basel. The firm plans load-bearing structures for buildings and bridges using all common construction materials (concrete, steel, timber, masonry, CFRP, and glass), and offers specialized services in special foundations, excavation support, condition assessment of existing structures, renovation and seismic retrofitting, expert opinions, and competition participation. It maintains a distinctive research edge in CFRP strengthening and bond modeling, anchored by Tomaz Ulaga's ETH Zürich PhD dissertation and co-authorship of the preliminary SIA 166 standard on externally bonded reinforcement.

The firm operates a project-based, fee-for-service professional services model targeting two primary customer segments: Swiss public-sector clients (cantons such as Basel-Stadt and Basel-Landschaft, municipalities, and federal entities including SBB and AWEL) requiring structural engineering for schools, sports facilities, administrative buildings, and infrastructure; and private developers and property owners (insurance companies such as Basler Versicherungen, real-estate firms including Allreal AG and Swiss Life Asset Management, and institutions like the Universität Basel / Swiss TPH). Go-to-market is driven primarily by participation in open architectural competitions (Projektwettbewerbe), where the firm has secured more than 25 documented first-place wins, and by long-standing collaborative relationships with leading Swiss and international architects including Herzog & de Meuron, David Chipperfield Architects, Morger Partner, Kunz und Mösch, and Berrel Berrel Kräutler.

With a team of approximately 12 staff — including two managing directors, three project managers, four structural engineers, one draftsman/technician, and one administrative employee — Ulaga Weiss AG is a founder-controlled, privately-held Swiss AG with no external investors, parent company, subsidiaries, or funding rounds disclosed. Operations are concentrated in Switzerland, with projects spanning Basel, Zürich, Bern, Winterthur, Aarau, St. Gallen, Geneva, and Liechtenstein. No pricing, revenue, or backlog figures are publicly disclosed; the firm relies on professional reputation, competition wins, and academic publication rather than traditional marketing channels.
