What Durth Roos Consulting does

Durth Roos Consulting GmbH is a German independent engineering consultancy founded in 1990 by Prof. Dr.-Ing. Ralf Roos, headquartered in Darmstadt with branch offices in Karlsruhe, Bonn, and Berlin. The firm provides consulting services across the full lifecycle of road and traffic infrastructure, including traffic planning, road design and construction supervision, project management, traffic safety audits, runway and airport surface engineering, road operations, and applied research. It employs more than 60 permanent staff plus a variable pool of freelancers, and serves a portfolio of 2,001 public-sector and private clients across Germany.

Complementing its consulting practice, Durth Roos develops and licenses a proprietary suite of 12 modular software products organized into four lines: Entsorgungslogistik (waste disposal logistics including container management and route planning), Betriebsdienst (operations service for winter maintenance, route inspection, and street cleaning), Erhaltungsmanagement (pavement management and systematic road condition assessment per FGSV guidelines), and Kundenspezifische Software (custom development). The software modules share underlying data infrastructure and support both internal consulting workflows and external licensing to municipalities, state administrations, and private service providers.

The business operates on a sales-led, direct-engagement model targeting German federal agencies, state authorities, municipalities, and private infrastructure clients through competitive bidding and public procurement, with selected cross-border work in Luxembourg. Revenue is generated through professional services fees plus software licensing and customization. The firm is privately held by founding principals (Ralf Roos and Thomas Weissenberger), reports annual revenue of approximately EUR 61 million, and maintains formal research and dual-study partnerships with KIT, Hochschule Darmstadt, Hochschule Karlsruhe, Bergische Universität Wuppertal, and Bauhaus-Universität Weimar to sustain its technical talent pipeline.
