What Doser Kempen Krause Ingenieure GmbH does

Doser Kempen Krause Ingenieure GmbH (DKK) is a German engineering firm specializing in bridge and civil engineering structures, headquartered in Aachen with a branch office in Brühl. The firm operates in the area of Tragwerksplanung (structural planning) and Objektplanung (object planning), delivering all HOAI service phases from feasibility studies through construction supervision, including new construction, rehabilitation, and demolition planning for Autobahnbrücken, Straßenbrücken, Geh- & Radwegbrücken, and Bahnbrücken. Its core technology is Building Information Modeling (BIM) used as a through-going 3D model-based planning and control method, combined with structural inspection per DIN 1076 and Bautechnische Prüfung (structural technical review) delivered by a state-certified Prüfingenieur.

DKK's revenue model is professional services, project-based, with fees governed by HOAI for public-sector and private-sector engineering mandates. The company earns through public procurement tenders and direct commissions, and augments this with paid VDI professional education seminars co-developed with WTM Hamburg. Customers are concentrated in the public sector: municipal, state, and federal infrastructure authorities (e.g., Aachener Stadtbetrieb, StädteRegion Aachen, Stadt Koblenz, Landesbetrieb Straßenbau NRW, Die Autobahn GmbH des Bundes), plus construction firms (RWE Power AG, Hochtief, Bruno Klein) and federal research institutions such as BASt.

The firm is privately held, owned by its three managing directors (Hans-Peter Doser, Dr.-Ing. Hans-Jürgen Krause, Dr.-Ing. Joerg Gallwoszus), and operates as part of the broader Kempen Krause Gruppe network through a strategic partnership with Kempen Krause Ingenieure for cross-disciplinary planning. With approximately 15 employees, DKK competes on regulated credentials (Prüfingenieur, Sachverständiger), domain specialization in bridge engineering (including flood-damaged infrastructure), and geographic proximity to NRW/RLP flood-affected regions.
