Railway Station Renovation Project Featuring Solutions by Tata Steel Reaches Final Stage of The Roofing Awards 2013

3 May 2013 No Comment


A major railway renovation project featuring a range of building envelope solutions by Tata Steel has been shortlisted for the Roof Sheeting category in the National Federation of Roofing Contractors’ prestigious Roofing Awards 2013. The Awards recognise and highlight the very best in all major roofing disciplines. Winners will be announced at the Awards Ceremony at the Hilton Metropole, London on May 17th.

nfrclogoThe original roofs over the Eastern “Kent” side of London Victoria Station had protected travellers for 150 years, but required extensive renovation.

London Victoria Station is one of the busiest railway terminals in the UK. Victoria is the start or end for over 70 million journeys a year.

There are effectively four railway stations on the site: two serving main line routes in south eastern England, one underground station serving the District and Circle Lines, and one deep-level tube line station.

The station has dedicated platforms for passengers travelling to Gatwick Airport on Gatwick Express Services. The area around the station has also become an important interchange for other forms of transport: a local bus station is in the forecourt, and a terminal for nationwide long-distance road coaches at Victoria Coach Station is nearby.

A Grade II listed building, the mainline station serves a range of longer-distance destinations in Kent and Sussex, including Brighton, Hove, Worthing, Eastbourne, Canterbury and Dover.

The station has a segmental tied arch roof with light iron tie rods arranged polygonally between radian iron struts. It comprises two spans, the first of which is 38m by 138m, the other is 39m by 117m.

After 150 years of protecting the travelling public from the elements, the original pitched roofs on the concourse and two main barrel-vaulted roofs over the Eastern “Kent” side of the station had reached the end of their working lives.

Network Rail obtained Listed Building Consent for the roof refurbishment through the City of Westminster and English Heritage.

Installation contractor Everlast Waterproofing Limited fitted R46 Roof profile to the two approximately 40-metre span, over 100 metre long main barrel-vaulted roofs, to a 26 metre radius curve, incorporating stippolyte obscure glazing, to match the original patent glazing system.


The replacement roof featured R46 profile in double-sided Colorcoat HPS200 Ultra®, with a Goosewing Grey finish on the external face and a Straw finish on the internal face. The R46 Roof Profile was selected by Network Rail due to its ability to span approximately 2.8m from purlin to purlin.

On the concourse, the existing felt roofing laid on timber purlins was replaced by steel purlins and C19 Wall Profile in Colorcoat HPS200 Ultra® in Goosewing Grey, laid over purlins at nominal one metre centres, with an internal PM13 Pressed Profile in Colorcoat HPS200 Ultra® in Straw, providing a like-for-like tongue and grooved boarding effect when viewed from the underside.

The existing translucent corrugated sheeting was replaced with stippolyte glazing mounted within a patent glazing bar system.

The internal colour choice of Straw was arrived at following extensive research into the concourse colour scheme, to ensure that replacement colours accurately interpreted the original Victorian paints.

Colour matches were also achieved on decorative spandrels, gutter mouldings, the maintenance access system, columns and low-level canopies.
