INGENIEURGRUPPE BAUEN

What INGENIEURGRUPPE BAUEN does

IngenieurGruppe Bauen (IGB) is a German owner-operated engineering partnership founded in May 1965 in Karlsruhe by four civil engineers. Operating as a Partnerschaftsgesellschaft mit beschränkter Berufshaftung (PartG mbB), the firm delivers structural engineering (Tragwerksplanung), independent technical inspection (Bautechnische Prüfung), building physics (Bauphysik), BIM-based digital planning, fire protection design, structural dynamics (Baudynamik), and project management across the full Leistungsphasen 1–9 of the German HOAI fee structure. With 252+ employees across five regional offices — Karlsruhe (114, HQ), Mannheim (69), Berlin (32), Freiburg (30), and Heidelberg (7, opened 2023) — IGB serves primarily German public-sector clients including federal agencies (Eisenbahn-Bundesamt, Wasserstraßen-Neubauamt, Bundestag), state authorities (LUBW Baden-Württemberg, Staatliche Museen Berlin), and municipalities, alongside selected private developers and industrial operators.

The firm's service portfolio is unusually broad for its size, spanning reinforced concrete, steel, timber, glass, and membrane structures, with rare specializations in EBA-certified railway bridge verification (five Prüfsachverständige), WHG-Konstruktionen, Betontechnologie, Glockenfachplanung, and DGNB/BNB sustainability consulting. Notable projects include the James-Simon-Galerie on Berlin's Museumsinsel, the Erweiterung Kunsthaus Zürich (David Chipperfield Architects), the Haseltalbrücke (Ingenieurbaupreis 2006), the Hochstraße Süd bridge in Ludwigshafen, the Stadthalle Heidelberg restoration, and 26 of the Neckar lock modernizations. The firm is ISO 9001 certified continuously since 2008 and holds seven partners with statutory Prüfingenieur recognition.

IGB is entirely partner-owned with no external funding rounds or M&A, generating revenue through project fees governed by HOAI fee ranges based on construction cost and complexity. Client acquisition relies on reputation, professional networks, referrals, and participation in public tendering processes, supported by active membership in DAfStb, VBI, VPI, Ingenieurkammer Baden-Württemberg, and Eurocode committees. The firm bills under multi-year contracts typical of German engineering consultancies.
