What ALTMANN Ingenieurbüro GmbH & Co. KG does

ALTMANN Ingenieurbüro GmbH & Co. KG is a privately held German engineering firm founded in 2008 by Matthias Altmann in Cham, Bavaria, and operating across three offices (Cham headquarters, Neutraubling near Regensburg, Aschheim near Munich) with approximately 70 employees. The firm delivers integrated general planning (Generalplanung) covering all HOAI Leistungsphasen 1–9 across six in-house disciplines: Hochbau (structural engineering), Tiefbau (civil engineering), Brückenbau & Ingenieurbau (bridge and structural engineering), TGA-Planung (building services), Bauleitplanung & Immissionsschutz (urban planning and noise protection), and Geotechnik (geotechnical engineering). Differentiated technical capabilities include an in-house geotechnical laboratory with drilling equipment up to 50 meters depth and advanced 3D planning software used for highly complex precast geometries such as the trapezoidal elements with curved soffit on the Abensbrücke project.

The firm generates fee-based professional services revenue under the German HOAI fee framework, winning mandates through public tenders and direct client relationships with municipalities, state construction authorities, and private developers. Approximately 300 projects are executed annually, with disclosed project volumes ranging from €2.5M for small municipal facilities (BRK Kita Kürnburgzwerge) to €110M for the Engelbergtunnel refurbishment on the A81. Customer segments are predominantly Bavarian municipal and public-sector clients (Staatliches Bauämter, cities, markets), supplemented by private industrial, sports, and real estate developers. Notable clients include Otto Lehmann GmbH, Smurfit Kappa, SSV Jahn Regensburg, OTH Regensburg, and GSB Sonderabfall-Entsorgung Bayern.

The business also extends into project development and investment through related ALTMANN Group entities (ALTMANN Immobilien GmbH & Co. KG, ALTMANN Immobilien Projekt GmbH & Co. KG), with the firm simultaneously acting as planner and developer/investor on projects such as the €35M Westumgehung Bad Kötzting Nahversorgungszentrum and the €13.6M Panoramapark residential complex (74 apartments). Marketing is project-referencing and relationship-driven, supported by an active social media presence across LinkedIn, Instagram, Facebook, YouTube, XING, X, and TikTok. Ownership remains with founder Matthias Altmann through ai Verwaltungs-GmbH; no external institutional investors are disclosed.
