The main offices of Plambeck ContraCon Bau und Umwelttechnik GmbH (Construction and Environmental Technology) are located in Cuxhaven, with branch on Helgoland. 


Cuxhaven is also the headquarters of the Plambeck group, where administrative services are performed centrally for all other offices. Each main office operates independently and has developed specific expertise; however, the group expertise is naturally equally accessible to all branches.
