British Gypsum partition and wall lining systems
have been installed exclusively as part of a £1.8 million drywall
package for the fit-out of the new St. Pancras International
station, one of London’s most famous landmark buildings.
The ‘jewel in the crown’ of the £5.8 billion High Speed 1 project, formerly the Channel Tunnel Rail Link, the new international station has been constructed within the existing and extended Grade 1 listed Victorian building, first opened in 1876.
Drywall specialists, London Drywall, used British Gypsum GypWall CLASSIC partitions to create division walls to retail units, business lounge and ticket areas in the ¾ mile long building. Based on 70mm & 146mm GypWall metal studs, the partitions were lined with 12.5mm Gyproc Wallboard, Fireline and MR board and included a plywood inner lining in all retail areas to facilitate fixing of display racking. Partitions were installed virtually independently at abutments using a special detail to meet English Heritage requirements for minimal fixing to the main structure.
Around perimeters, the original Victorian red brick walls have been lined with GypLyner UNIVERSAL metal frame wall lining. Gyproc moisture resistant and DUPLEX grade plasterboard linings were specified at external walls because of the high levels of moisture inherent in the existing Victorian brickwork structure.
One of the more unusual features of the project was a 200 metre long fire–rated access tunnel which London Drywall designed and constructed in association with British Gypsum technical experts, in order to provide security and safe pedestrian access to work areas through ‘live’ sections of the station.
The 3-metre high X 2.8-metre wide fully enclosed tunnel was constructed of Gypframe 70mm metal stud, lined internally and externally with two layers of 12.5mm Gyproc FireLine board to provide 60 minutes fire protection in both directions. The design incorporated 600mm long drywall buttresses at 3-metre centres each side of the tunnel
to provide stability without the need for fixing into the existing structure. The temporary construction, which was subsequently demolished, replaced an original concrete panel specification, providing a more sustainable solution, which offered significant savings in both cost and time.
With the added complexity of working on a site which effectively remained open to the public throughout the major refurbishment works, London Drywall’s team of up to 50 dryliners and Managers, working under Fit-Out Contractor, ISG plc, had to work against the clock in order to complete all works in time for the grand opening by The Queen on 6th November and the commencement of Eurostar scheduled rail services on 14th November.
When the High Speed 1 project is completed, the new rail link from St Pancras International will carry passengers from the UK’s capital to the heart of Europe at an eye-watering 186 miles an hour - a journey that station designer William Barlow could never have envisaged when he first sat down at his drawing board in 1863!
All British Gypsum products for the project, a Costain O'Rourke Bachy Emcor Rail Joint Venture, were supplied by Sheffield Insulations, of Barking.
