Project Description


Biggin Hill Airport, UK.

aircraft-hangar-terminal-hangar15The brief required a 120m wide terminal hangar, split into three areas, two of which had to be accessible simultaneously, with a maximum height of 15m and one span designed to house a Boeing Business Jet (BBJ).

Biggin Hill Airport Ltd chose the successful partnership of Civils Contracting Ltd and REIDsteel to fulfil this brief.
For our unique solution the hangar door has nine slabs and three tracks with a tailgate door.
Three slabs are designed to jump the gap dictated by the BBJ requirement and the remaining two spans are high enough at 9.2m tall to allow the entry of the more usual type of business jet.

These hangar doors are sheeted in microrib profile composite panels manufactured by Kingspan, and they include personnel doors which have no threshold to them. The Hangar also features a service door for towing trucks or deliveries.

The 4.3m tall tailgate opening takes the available height to 13.5m.
Innovative engineering allows the slabs to ‘jump’ the 3m gap created in the top track by the tailgate opening.

Most of the weight of the doors is borne by the bottom rolling track.
The top track supplies stability and the power to the door motors and controls.
