Alpha Rotex: Stable and yet in motion?

Alpha Rotex: Stable and yet in motion?
INGENIEURBÜRO DR. BINNEWIES

There are plenty of high-rise buildings. Some are ordinary. Some are impressive. And some are outstanding. What characterises Alpha Rotex is not just its location. Not just its triangular cubature. And not just its aspiration to LEED gold certification. It is its visibility, with a height of some 68 metres as the highest building at Frankfurt Airport.


The banded facade made of aluminium and glass strikingly subdivides the building along the horizontal plane. The foyer, with 8 floors and 5 winter gardens, the latter each 30 metres high, impressively displays the vertical plane to the visitor.


Stable and yet in motion? There’s much rotation in Alpha Rotex. Rotation is change. The building's wings revolve around its core, and from the eighth floor upwards they change their alignment with an exact symmetrical mirroring of the ground plan. The supporting structure of flat slabs with support widths of up to 13 metres is organised so that all the support strands pass through from the roof into the foundations without expensive retaining constructions.

Brand description
We are about 90 qualified and highly motivated civil and structural engineers and are fully aware that the statics of today’s buildings demand increasingly more sensitive solutions. At times external circumstances can, however, become too complex for words. On the one hand, there is the client with his justified requirements, followed by the architect on the other hand, with his outstanding planning and design concepts. And right at the end, there is nature, apparently not taking any consideration whatsoever and opposing any type of building work. This is the challenge that engineers are confronted with and will have to find a fair solution for. The INGENIEURBÜRO DR. BINNEWIES builds on Dr Binnewies’ professional experience of more than 50 years, representing more than five decades of progress in structural engineering and also an awful lot of time to increase the knowledge.
