In the commune of Falkenhagen (Mark), district of Märkisch-Oderland (Brandenburg), six wind turbines of the manufacturer Enercon (E-126) have been erected. We were responsible for the construction of the foundations. A special feature of this project was that the turbines are of a type of tower (MST) that has been almost untested to date. This was accompanied by the installation of a new type of flange connection as an adaptive element between the foundation and the later tower. Its construction was part of our building work.
