ZECH construction

What ZECH construction does

ZECH Bau SE is a German general contractor headquartered in Bremen, delivering turnkey construction (Schlüsselfertigbau), renovation, and modular building services to corporate, public sector, real estate developer, and hospitality clients. Founded in 1909 and operating today as part of the family-controlled Zech Group SE (via strategic holding ZECH Building SE), the company employs between 5,001 and 10,000 people and maintains 19+ regional offices across Germany plus subsidiaries in Austria (Vienna) and Romania (Bucharest). Its customer roster includes Flughafen Berlin Brandenburg (BER Terminal 2), Siemens (Campus Erlangen Module 2 — Germany's largest wood-hybrid project), Messe Frankfurt (Hall 5, ~EUR 153M), Sparkasse Bremen (EUR 52.5M Campus), Olympus, Kühne+Nagel, BVG, DGB, ADAC Nordrhein, and Deutsche Rückversicherung.

The company's core offerings center on the proprietary Smart Construction partnering model — nine modular components combining BIM, Lean Construction, integral data-based planning, and digital collaboration tools — and the CREE by ZECH wood-hybrid modular construction system, which the company claims achieves approximately 80% CO2 reduction versus conventional concrete construction and approximately 20% shorter build times. Supporting technology includes Digital Twin-enabled pre-fabrication, TÜV Nord certifications (ISO 9001, ISO 14001, AMS Bau), and DGNB Platinum certification (Neubau Zollverein Essen, 82.6% fulfillment).

Revenue is generated through project-based lump-sum (Pauschalpreis) turnkey contracts priced individually and delivered over multi-year durations, with no public pricing tiers or recurring revenue streams. Go-to-market is enterprise field sales via the regional branch network, targeting large project developers, corporations, and public-sector entities; there are no intermediaries or resellers for core construction services. In January 2026, ZECH Bau jointly acquired approximately 320 employees and assets from the insolvent Karrié Baugesellschaften via asset deal, indicating ongoing inorganic expansion alongside organic contract growth.
