What Finsterwalder Bau-Union GmbH does

Finsterwalder Bau-Union GmbH (FBU) is a privately held German general contractor founded in May 1990 and headquartered in Sonnewalde, Brandenburg. The company provides turnkey construction (Schlüsselfertigbau) across six integrated divisions: industrial construction (Industriebau), logistics and hall construction (Logistik- und Hallenbau), construction on existing buildings (Bauen im Bestand), multi-story construction (Geschossbau), underground and pipeline construction (Tief- und Rohrleitungsbau), and engineering construction (Ingenieurbau). Its signature "FBU-Prinzip" combines Hochbau (structural) and Tiefbau (civil/underground) services from a single source, supported by more than 25 in-house engineers, integrated BIM-based planning, drone surveying, and 360° laser scanning capabilities.

FBU serves enterprise clients across logistics (DACHSER, EDEKA, HELUKABEL, Fresenius Kabi), automotive (Audi, Magna, Eberspächer, FEV), energy and waste management (EEW Energy from Waste, ALBA Recycling), retail (Kaufland), manufacturing (Böllhoff), and public-sector clients (municipal utilities, Abwasserzweckverband Döbeln-Jahnatal). A wholly-owned subsidiary, EVR GmbH, internalizes earthworks, shoring, demolition, and construction material recycling. The company operates three offices — Sonnewalde (HQ, Brandenburg), Leipzig (Saxony, established 2008), and Berlin (opened 2025) — and holds certifications including ISO 9001:2015, ISO 14001:2015, ISO 45001:2023, VOB Prequalification, and multiple RAL Gütezeichen.

Revenue is generated through project-based general contractor contracts priced individually by scope, complexity, and duration, with services spanning project planning (HOAI Leistungsphasen 5+), execution planning, structural engineering, technical building equipment, project management, interface management, and surveying. Annual construction output is consistently reported at €40-60 million with a workforce of 125-130 employees as of 2025. The company has grown entirely organically since 1990 with no external funding rounds, M&A activity, or private equity involvement; it is led by four managing directors (Jens Kilian, Henrik Marschetzky, André Stascheit, Armin Hess) supported by authorized signatories (Mario Kutscher, Gregor Marschetzky, Stephan Kutscher).
