KEMNA BAU Ost GmbH & Co. KG

What KEMNA BAU Ost GmbH & Co. KG does

KEMNA BAU Ost GmbH & Co. KG (KBO) is a German civil engineering and infrastructure construction company headquartered in Leipzig, operating as a wholly-owned subsidiary of the KEMNA-Gruppe. Founded in April 2016 through the merger of Tesch Straßenbau GmbH & Co. KG and the Leipzig branch of KEMNA BAU Andreae GmbH & Co. KG, the company employs over 340 staff across three offices in Leipzig (HQ), Berlin, and Magdeburg (Schönebeck an der Elbe). KBO specializes in Verkehrswegebau — traffic route construction — with a service portfolio spanning road construction, earthworks and civil engineering, asphalt construction, canal and pipeline construction, landfill construction, dike and water engineering, railway civil engineering, natural stone paving, contaminated site remediation, and certified waste management (Entsorgungsfachbetrieb under § 56 KrWG).

The company's revenue model is project-based: KBO bids competitively for public infrastructure tenders and negotiates directly with private developers. Public sector clients dominate — state agencies (Landesbetriebe), municipalities (Landeshauptstadt Magdeburg, Bezirksamt Mitte Berlin), federal entities (DEGES, Autobahn GmbH), and Deutsche Bahn (DB Netz AG) — with secondary exposure to private developers such as Bonava and agricultural clients. Project execution is delivered through direct enterprise field sales and via Arbeitsgemeinschaft (ARGE) consortiums with larger contractors (Wayss & Freytag, Hochtief Infrastructure, SEH Engineering, Hentschke Bau, Glass Ingenieurbau) for mega-projects such as the A10/A24 Havellandautobahn expansion and the Strombrücken Magdeburg replacement.

Market access is gated by an extensive certification portfolio: DQB national prequalification (101.002837) covering 15 Leistungsbereiche, Deutsche Bahn AG earthworks prequalification, Güteschutz Kanalbau AK2, DVGW Fachunternehmen, ISO 9001/45001/50001, BU-Fachbetrieb, WHG-Fachbetrieb, QGS urban road construction seal, and ZTV-ING Part 6.1 cast-asphalt certification. The technology stack is conventional construction equipment; no proprietary software, patents, AI/ML systems, or apps are disclosed. Geographic focus is eastern Germany — Saxony, Berlin, Saxony-Anhalt, Brandenburg — with no international footprint claimed.
