Revenue model

1. Construction project contracts: The company generates revenue primarily through fixed-price contracts for construction projects ranging from small residential builds to large infrastructure projects. Revenue is project-based, one-time, and calculated on a per-contract basis. Major projects include civil engineering works for Berliner Wasserbetriebe, multi-family residential buildings, commercial buildings, and government facilities. The company acts as general contractor (GU/GÜ) or lead contractor in joint ventures (Arge).
2. Turnkey construction (Schlüsselfertigbau): The company also offers turnkey construction services (SF-Bau), managing projects from design through final handover, providing a complete bundled service.
3. Engineering consulting services: Internal engineering services provided by own civil engineers (Bauingenieure) for project execution, often cited as a key differentiator — full in-house engineering coverage.
