Bleck & Söhne Hoch- und Tiefbau GmbH & Co. KG

What Bleck & Söhne Hoch- und Tiefbau GmbH & Co. KG does

Bleck & Söhne Hoch- und Tiefbau GmbH & Co. KG is a family-owned German construction company founded in 1940 in Berlin and now in its fourth generation of family leadership. The company operates as a general contractor (Generalunternehmer) and subcontractor (ausführendes Unternehmen) delivering both Hochbau (above-ground) and Tiefbau (below-ground) construction projects, with primary service territory in Berlin-Brandenburg. Its customer base is heavily weighted toward the public sector, including recurring work for Berliner Verkehrsbetriebe (BVG), Berliner Wasserbetriebe, DB Station&Service, the Bundesamt für Bauwesen und Raumordnung, and the Senatsverwaltung für Stadtentwicklung, supplemented by private residential developers and housing cooperatives. Project values range from approximately €2.2M for smaller renovations to €141M for large public infrastructure contracts (Airport BER rail connection), frequently executed via joint ventures (Arbeitsgemeinschaften/ARGE) with other construction firms.

The company's technical core spans turnkey (schlüsselfertig) building construction, complex renovation including heritage-protected structures (Denkmalpflege), concrete restoration, and facade engineering on the Hochbau side, and a differentiated trenchless pipeline and sewer construction capability on the Tiefbau side. The Tiefbau portfolio includes microtunneling/Rohrvortrieb (pioneered since 1985 with seven specialized drive systems up to DN 1200), the proprietary hydros PLUS process for trenchless pipe replacement (over 25 km of drinking water pipelines since 1992), Primus Line flexible pipe rehabilitation for high-pressure applications (introduced to Berlin in 2007), pipe-eating renewal, and pipe pulling/insertion methods. The company holds certifications that function as hard market-access gates: DVGW GW 301 (open pipeline construction), GW 302 (trenchless replacement), RAL-GZ 961 with Güteschutz Kanalbau Membership No. 5 (one of the first nationally), Präqualifikation, and Güteschutzgemeinschaft Betoninstandsetzung membership.

The business model is project-based and contract-driven, with revenue generated through competitive public tenders and direct negotiation with private developers; pricing is not publicly disclosed and varies materially by project scope. The company employs approximately 200 qualified staff (per company website, contradicting the firmographics count of 20) and operates from its headquarters at Riedemannweg 16-18, Berlin-Charlottenburg. It has no external funding, no public listing, no M&A history, and no disclosed subsidiaries beyond the Verwaltungs GmbH general partner entity. Marketing is relationship-driven, leveraging a detailed project portfolio on bleck-soehne.de, LinkedIn, Instagram, Facebook, and XING, with direct sales and public tender pursuit as the primary GTM motions.
