Alpha Rotex in Gateway Gardens, Frankfurt
Special project

Customer Hochtief Solutions AG
Construction
 02/2012 to 03/2013

The building
At 66 m with 16 stories and two basement floors, Alpha Rotex is the tallest building in Gateway Gardens, a new district in Frankfurt right at the airport.

The new office building comprises more than 25,000 m² of rental space, 316 parking spaces and additional warehousing space.

The brief
As the airport is so close, the cranes were not allowed to exceed a height of 180.0 m above sea level.

The implementation
At 179.95 m above sea level reached by the WT 300 e.tronic with a hook height of 89.78 m in the second phase, this requirement was met almost exactly. It grew by precisely 4.0 m with the custom made tower elements produced especially for this project.

All the crane towers consisted of 2.0 m tower elements so that work could be carried out with the same climbing frame.
