Steelway’s expertise in metal bracketry and
staircase construction has been used to good effect on the Piccadilly Line
extension to Heathrow’s new Terminal 5 complex. This included escape walkways,
passenger escape stairs, specialist brackets, Fireman Escape Stairs and a
passenger fire escape staircase.
The project involved work to both the
tunnels, escape and access staircases under the terminal. This included
detailed multi functional and adjustable brackets to ensure correct alignment
of the walkways in relation to the track. These specialist brackets were an
integral part of the specification to compensate for the build tolerances along
the full length of the 4 kilometre track.
Fireman Escape Stairs & Passenger Fire
Escape StaircasesAnother key element of the project was the
design, supply and installation of the passenger escape stairs and fireman
access stairs beneath the terminal. These were designed as modules and clad in
specialist fire resistant cladding. The modules weighing some 30 tonnes where
transported at night across the runways and craned into position. The total
project costs amounted to 2 million pounds.
