The football stadium BayArena - the home stadium of the club "Bayer 04 Leverkusen" will be modernized, reconstructed and adapted for an audience of more than 30.000 persons.
The roof of the stadium shall be the characteristic feature.

The KOCKS ENGINEERS were contracted by the company Max Bögl Stahl- und Anlagenbau GmbH & Co. KG with the workshop design of the extensive installation devices for the roof construction.
In detail, the following static calculations and workshop drawings were drawn up:
    • For the installation in sections of the compression ring consisting of top boom and bottom chord and diagonal compression, putlog towers were essential to take the load of the compression ring. The towers were secured by means of stays.
    •  The compression ring had also to be fixed by stays. The load acting on the stays had to be beared on existing concrete parts of the tribune via steel constructions. A concept for suitable claps on the compression ring had to be made up for a preliminary rope fixing.
    •  For the preassembly of single roof segments a device taking up the purlins for their installation was developed and designed. An elevator was designed for the transport of these segments into their final position via crane, an elevator was designed.       
For all steps of the measure, the feasibility regarding construction and economic reasons were the central question. The services were carried out in close co-operation with the client, the engineers and the site office.
