What Sigma Ingenierie does
Sigma Ingenierie (legal entity SIGMA INGENIERIE S.A., Code APE 7112B) is a privately held French structural engineering firm founded in 1977 and headquartered in Le Mans (2 bd Paul d'Estournelles de Constant, 72000), with a second office in Alençon and a workforce of approximately 30 employees. Operating as a bureau d'études techniques (BET), the firm specializes in structural engineering studies for buildings with particular expertise in reinforced concrete (béton armé), delivering design plans during the maîtrise d'œuvre phase and execution plans during construction, including foundation calculations, structural concrete plans, and reinforcement/formwork documentation. The firm holds OPQIBI qualification n°18123733 covering standard concrete structures, complex concrete structures, structural restoration, and routine seismic studies, and serves clients across eight verticals — residential, public facilities, education, retail, infrastructure, leisure, industry, and offices — throughout France.
The firm operates a project-based professional services model, billing per engagement through direct contracts with architects, public and private project owners (maîtres d'ouvrage), general contractors, artisans, and earthwork companies. Its technology stack consists of licensed industry-standard CAD/CAE tools — GRAITEC (Arche, Advance Design, Melody), Revit BIM, Autocad, and Allplan — used to produce structural calculations and BIM-coordinated execution documentation. The sales motion is consultative and relationship-driven, anchored in technical reliability and nearly 50 years of track record (15,000+ completed projects since 1977). Ownership is 100% private, distributed between executives and senior managers (President Laurent Bougard and General Director Éric Hébert), with no venture capital, private equity, or parent company involvement and registered capital of €200,000. Marketing relies on website portfolio visibility, demonstrated sector breadth, and professional referrals rather than outbound demand generation.
