What HEG Consulting Engineers does

HEG Beratende Ingenieure is a German consulting engineering firm founded in 1991 and headquartered in Dortmund, with a second office in Berlin. The firm provides structural engineering (Tragwerksplanung), building physics (Bauphysik), Building Information Modeling (BIM), building preservation (Bauwerkserhaltung), construction-safety coordination (SiGeKo), and expert appraisal (Begutachtung) services to real estate developers, public-sector clients, industrial companies, and cultural-heritage foundations across Germany. Core technical work spans 3D CAD structural design, reinforcement detailing, finite element analysis, energy and thermal-bridge simulation, 3D laser scanning of historic structures, and Open-BIM interdisciplinary coordination. The company is structured as two private limited companies — HEG Beratende Ingenieure GmbH (Dortmund, HRB 14037) and HEG Beratende Ingenieure Berlin GmbH (Berlin, HRB 78370) — owned and managed by a partner group.

Revenue is generated through fee-based engineering consultancy engagements priced under the German HOAI (Honorarordnung für Architekten und Ingenieure) framework, structured across defined performance phases (Leistungsphasen 1–9). Projects are typically one-off, commissioned through direct client engagement, architectural competition wins, and partnerships with architecture firms; HEG operates as a specialist within multi-disciplinary planning teams rather than as a lead designer. Its differentiated positioning rests on three pillars: (1) being a recognized national pioneer in BIM-based digital planning — notably through Germany's first BIM-based building permit at the Louis Opländer office building; (2) deep specialization in industrial heritage conservation, with a documented track record at UNESCO World Heritage sites (Zeche Zollverein, Kokerei Hansa) and other Ruhr-area industrial monuments; and (3) material-optimization expertise demonstrated by projects such as Nordbahnstraße 12, which achieved 96 kg of reinforcement steel per m³ of concrete versus a typical industry benchmark above 120 kg/m³. The firm's methodology is rooted in the "Dortmunder Modell Bauwesen" collaborative approach developed at TU Dortmund, and its team includes multiple state-certified expert witnesses for sound, thermal, and heritage structural engineering.
