In the method of building a hybrid tower, a metal mast (4) is erected and connected to a foundation (11) and a concrete structure (3) is built around the metal mast by using the metal mast as a support. Afterwards, the metal mast is disconnected from the foundation and lifted by telescoping and guiding the metal mast along concrete structure. Finally, the lifted metal mast is connected to the concrete structure. |
