What Kemna Bau Ost does
KEMNA BAU Ost GmbH & Co. KG is a regional operating subsidiary of the KEMNA-Gruppe (legal parent: KEMNA BAU Andreae GmbH & Co. KG, headquartered in Pinneberg, Germany), focused on traffic infrastructure construction in eastern Germany including Berlin. The KEMNA-Gruppe was founded in 1867 in Breslau as a machine factory, evolved into road construction equipment, and post-WWII rebuilt under Dr. Karl Andreae in Hamburg. It has been family-controlled since, with Jacob Andreae and Michael Liell currently serving as Managing Directors. The group employs approximately 2,200 people across more than 70 locations in Germany, including dedicated branches in Hamburg, Leipzig, Berlin, Hannover, Neuss, Gelsenkirchen, and Bad Harzburg, plus specialized subsidiaries (VAM, ASPA, MDB, GEHRKEN, Daniel Kunz, ITB Ingenieurtiefbau, Guss-Asphalt Ceh, BiB, Steinbruch Lasbeck, KEMNA Schwerin).
The group's business is structured around three vertically integrated pillars: Verkehrswegebau (road construction covering autobahn expansion, bridge rehabilitation, airport runways, railway infrastructure, earthworks, drainage, paving, and structural rehabilitation); Asphaltproduktion (asphalt mix production from mobile and stationary mixing plants with electronic recipe control, polymer-modified bitumen per TL Bitumen-StB, and a recycling management system using granulators to reuse reclaimed asphalt); and Rohstoffgewinnung (aggregate extraction from quarries and gravel pits, including rail transshipment facilities with 400 t/h capacity and over 20,000 tons of storage). Specialized services include Bauwerksinstandsetzung (structural rehabilitation per DIN EN 1504 and ZTV-ING), Erd-/Deich-/Deponiebau (earthworks, dyke construction, landfill construction), and Spezialbau (compaction asphalt, open-porous and water-permeable asphalts, DSH-V thin-layer sealing).
The business model is contract-based: revenue is generated primarily through competitive tenders for public sector infrastructure projects (German federal government, Deutsche Bahn, municipal authorities), with secondary revenue from sale of asphalt mix, polymer-modified bitumen, and aggregates to both internal construction projects and external customers. Distribution is direct via the subsidiary and branch network, with road construction products (seam and joint sealing, crack repair, pothole treatment) delivered from Hamburg and Leipzig throughout Europe. The company holds PQ-VOB national pre-qualification, DB AG railway certification, ISO 9001/45001/50001 certifications, and EMB value management certification, collectively qualifying it for institutional infrastructure tenders.
