Biggin Hill, UK
In order to house two new aircraft, including a BAe146 with a 26.2m wing span and a Dassault Falcon 900 with a 19.3m wing span, new doors and an extension of the T2 hangar at Biggin Hill Airport were required. This would increase the door height from 7.62m to 9.25m.
There are 6 door slabs on 3 tracks, giving an entrance 34m wide by 9.25m high. The doors are all electrically operated, and can be moved independently of each other. The hangar doors have a fail-safe opening and closure system which is operated by a handheld pendant. In the event of a power failure the motors can be disconnected and simply pushed.
The doors are insulated with microrib composite panel cladding, and designed to withstand an hourly wind speed of 22 metres/second.
The door hood steel frame was erected independently from the existing hangar steel frame. REIDsteel erected the steel, fitted the cladding and wired and commissioned the electric doors, whilst maintaining access into the hangar for plant etc.
The advantage of this extension was that the client is able to house aircraft which are higher than that which the original T2 was ever designed to accommodate.
