T INGENIERIE

What T INGENIERIE does

T INGENIERIE (stylized as -T-; legal name T ingénierie SA) is a privately-held Swiss civil and structural engineering consulting firm headquartered in Geneva, with secondary offices in Lausanne and Istanbul. Founded in 1920 as Maillart & Meisser by the celebrated engineer Robert Maillart, the firm traces a continuous lineage through Tremblet SA (1950) and T ingénierie sa (1970), merged with Babel ingénieurs SA in 2007, and rebranded to -T- in 2011 with a refreshed identity launched in 2021. The firm specializes in bridges and civil structures (ouvrages d'art), administrative and residential buildings, transformations and renovations, villas, and urban civil engineering — including reinforced concrete, prestressed concrete, steel structures, mixed steel-concrete systems, cable-stayed and suspended bridges (notably the world-record 1,408m Third Bosphore Bridge railway span), diaphragm walls, deep foundations, and lightweight slab technologies such as Coblax.

The firm offers full-lifecycle engineering consulting: competition (concours) and tender (appel d'offres) participation, preliminary and feasibility studies, project studies, execution studies, construction supervision, multidisciplinary pool management (with teams of approximately 60 engineers on large international projects), expert assessments, and owner assistance. Revenue is generated through fee-based professional services contracts with public authorities, private developers, property owners, and international project consortia, secured via competitions, public tenders, and direct commissions. The firm serves federal and municipal clients (OFROU, Genève Aéroport, Ville de Genève, Ville de Vernier, SIG, HUG) and private developers (PG Promotor, AC Immo SA, Anlagestiftung Pensimo), with notable international reference projects including the Third Bosphore Bridge (Turkey) and Passerelle Nelson Mandela (France).

The firm is led by Romain Granai (Administrateur since 2007) and operates with 80+ team members across sectors (engineering, drafting, IT, partnerships, direction, apprentices). It maintains active memberships in SIA, AGI, USIC, FIB, AIPC, SZS, and VSS, and has received awards from FIB (2006-2010), ECCS (2010), and IABSE (2018) for outstanding structures. No public listing, institutional investor, or PE/VC backing is disclosed in the source material.
