In order to accommodate larger aircraft in the smallest of its three maintenance hangars, Lufthansa Technik asked REIDsteel to design an extension of 20m deep and 20m high under the central door head of this 90m span hangar.
The design team worked under the constraint that this new extension was to be constructed on top of the existing apron which could only accept shallow excavations. This led REIDsteel to recommend that an electrically operated fabric curtain door from Megadoor be used.
This type of door needs less intrusive civil-works than a ground bearing slab-sliding type of hangar door. However, some ground work is still essential to prevent rainwater hitting the front of the hangar collecting at the bottom of the doors and contend with rainwater running across the apron area. All of this water has to be diverted away from the door zone to help minimise the risk of water ingress beneath the door and across the hangar floor.
Steelwork and cladding was designed, supplied and erected by REIDsteel and the end result is a very neat and hugely accommodating extension, that incorporates translucent door fabric to allow diffused daylight into the hangar, and wall mounted louvre/ridge-vent combination that help to provide a comfortable and productive working environment.
The Megadoor was a five curtain design which when raised produced clear heights of 20m in the centre section, dropping to 18.5m and then 15m in the outer sections.
“Many thanks for the handover last week and for conducting such a smooth running project till the end. It was a very profession job all the way and it was a pleasure to have the opportunity to work together again.” LTM’s Project Manager.
