Foundation Construction

Foundation Construction

Work Scope

Our foundations ensure the stability of the wind turbines and transfer all loads coming from the tower and the turbine’s rotor movement to the subsoil. Pure gravitational foundations and circular slabs consisting of concrete and reinforcement steel anchored back on piling solutions are the standard footing technology for chosen wind turbine sites onshore. The site and its different founding locations with its subsoils must be carefully investigated initially by borings and cone penetration tests in order to ensure the bearing capacity. The basic foundation design for turbines of the modern multi-megawatt class is circular. The turbine tower is connected to the foundation by its grouted flange and pretention anchor studs.

We at SEEWIND elaborated a very competitive detailed construction execution concept for wind turbine foundations. Our specialized teams are doing just this all year around and eager to find even more optimization details for our customer’s best business case savings.
