What Wayss and Freytag does
Wayss & Freytag Ingenieurbau AG is a German civil engineering contractor founded in 1875 and headquartered in Frankfurt am Main. The company delivers complex infrastructure projects across tunnel construction (rail, road, metro), special foundation engineering, bridge construction, civil/structural engineering, and building preservation/rehabilitation. Its core technical capabilities center on mechanized tunneling, underwater immersion techniques (notably for the Fehmarnbelt immersed tunnel), ground engineering, and BIM-based digital construction methodologies, with stated certifications including DIN EN ISO 9001, 14001, 45001, 50001, and BIM-Qualifikationsnachweis.
The business model is project-based, generating revenue through public and private construction contracts, typically as general contractor or consortium partner on multi-year infrastructure programs. Customers are predominantly public-sector infrastructure owners (Deutsche Bahn, Autobahn GmbH, DB InfraGO, municipal utilities such as Stadtwerke Düsseldorf, TenneT) supplemented by selective private developers (PANDION Group, Ernsting's family). Following its 2022 acquisition by ZECH Building SE (divested by Royal BAM Group nv), the company operates as part of the ZECH Group, with annual construction output reported at approximately €900M and headcount of roughly 1,000 employees. Revenue mechanics derive from milestone-billed, fixed-price or unit-price contracts on long-duration projects (often 5+ years), creating lumpiness tied to public infrastructure spending cycles.
