HASSELMANN GmbH


HASSELMANN GmbH was founded on 14 May 1998 through the takeover of the company Heinz Hasselmann from Kirchweyhe near Bremen in Berka/Werra, Thuringia.

Although a fundamental change in ownership took place with this new company, we kept the company name “Hasselmann”.

The new company developed positively from the very beginning and the core areas of railway construction, municipal construction and civil engineering quickly emerged. Although our company is mainly specialised in the tasks around the Deutsche Bahn AG, we are also partner for numerous other customers in the private and public sector today.

The company’s headquarters in Berka/Werra is located on the border between Hesse and Thuringia, directly on the A4 federal motorway. In order to ensure optimal coverage and individual and personal support for customer projects throughout Germany, our plant was opened in Plauen in April 2011.


We build successes

The HASSELMANN GmbH team currently comprises over 200 highly qualified and motivated specialists of its own. They work nationwide in railway construction, municipal construction and civil engineering for the success and satisfaction of our partners. Our employees have modern machinery and the latest computer technology at their disposal to implement their tasks professionally. In this way, we create the basis for best work performance and thus ensure consistently high quality with minimum construction time. As a customer, you can be assured of having a contact person with a high degree of know-how to help you in all service areas.
