HERZOG Gruppe

What HERZOG Gruppe does

HERZOG Gruppe is a German family-rooted construction services group headquartered in Marburg, operating through four regional branches (Marburg, Erndtebrück, Tüttleben, Andernach) and serving clients across Central Germany, Rhineland-Palatinate, Thuringia, and North Rhine-Westphalia. The company delivers a comprehensive portfolio of construction services across six core disciplines: Spezialtiefbau (specialist foundation engineering including vibration piling, driving, pressing, anchoring, and soldier pile walls), Hochbau (building construction and concrete repair), Erd- und Straßenbau (earthworks and road construction), Leitungsbau (pipeline and utility construction), Wasserbau (hydraulic engineering and renaturation), and Schlüsselfertiger Anlagenbau (turnkey plant construction for water and wastewater facilities). Its most distinctive technical capability is railway bridge construction under active rail operations (Bauen unter rollendem Rad), a safety-critical niche in which the Andernach branch operates as a long-standing partner of Deutsche Bahn.

The business model is project-based B2B construction services with no recurring revenue streams. Pricing is quote-driven via competitive public-sector tendering and private bidding; no standard pricing tiers are published. Annual construction output (Jahresbauleistung) is approximately 70 million EUR, supported by 300+ employees and a modern machinery and vehicle fleet. Customers are predominantly German public-sector entities — federal/state road authorities (Hessen Mobil, Landesbetrieb Straßen NRW), municipalities (Stadt Mainz, Stadtverwaltung Erfurt, Magistrat Stadtallendorf), water and flood authorities (Wasserverband Nidda, AZV Finne, Gewässerverband Salzbödetal), and Deutsche Bahn — with a smaller secondary segment of private commercial and industrial clients. GTM is enterprise field sales through regional branches. Effective January 1, 2023, HERZOG was acquired by Peter Gross Bau, a 4th-generation family construction group (2,400 employees, 650M EUR annual volume) based in Sankt Ingbert; HERZOG continues to operate as an independent business unit with its existing Vorstand (Oliver Amon, Enrico Kretsch) and Philipp P. Gross as Chairman of the Supervisory Board.
