What ARU - Ingenieure, Architekten und Sachverständige does

ARU Ingenieurgesellschaft mbH is a privately held German engineering, architecture, and certified expert witness firm headquartered in Lingen (Ems) with a second office in Steinfurt. The company is owner-managed by three managing directors — Benedikt Beckmann, Tobias Dankert, and Dirk Baldauf — and operates through a group structure that includes two wholly-owned subsidiaries: ARU Prüfingenieur & Umweltgutachter GmbH (testing engineering and DAU-accredited environmental auditing) and BALDAUF ARU ARCHITEKTUR GmbH (architectural services). The firm reports 40+ employees across both locations and a track record of 1,500+ completed projects serving 500+ customers.

The company's service portfolio is organized around two integrated practice areas. The first covers environmental compliance and industrial safety, including immission control and permitting under BImSchG, plant safety under Störfallverordnung, water and soil protection under AwSV and BBodSchV, explosion protection, fire protection, occupational safety, renewable energy certification under EEG, and management systems (ISO 9001, 14001, 45001, 3834). The second covers architecture and building services — residential, commercial, industrial, and rural building design — together with technical building equipment (TGA) planning and digitization services built on the digem platform. ARU holds multiple government-authorized certifications (§ 29b BImSchG, § 53 AwSV, IQ-Zert fire protection, DAU environmental auditor, IHK-certified expert) that are prerequisites for legally binding compliance documentation in Germany.

Revenue is generated through professional services fees following HOAI rate structures for architecture work and project-based billing for engineering and expert services, with multi-year contract cadence. The firm serves industrial, commercial, agricultural, and private clients regionally across Lower Saxony and North Rhine-Westphalia; named enterprise customers include PreZero Battery Recycling, Krombacher, Vion, Hoppecke, EmsFlower, Greiwing, and Relionbat. No public revenue disclosure, external investors, or M&A activity are present in the data.
