Whitechapel Station, London

Success under pressureCrossrails Whitechapel station required doors that were security rated and fire, sound and…  …pressure resistant.


The Crossrail C512 Whitechapel Main Station Works is part of the Elizabeth Line project. The Elizabeth line runs for 60 miles starting from Reading and Heathrow in the west, passing through London and out to Shenfield and Abbey Wood in the east.

Expected to serve around 200million passengers a year, the railway will have 41 stations, of which, 10 are newly built and 30 upgraded.

Whitechapel station is an interchange for both the Hammersmith & City and District Lines and London Overground. The new Elizabeth Line station is interwoven with the existing transport services linking to an elevated station concourse.

The works being carried out by BBMV (Balfour Beatty, Morgan Sindall and Vinci Construction) include 5 shafts and 500m of platform. The complexity and scale of the works is comparable to building an ocean liner underground with access for all work via the funnels!

The scope of the project.

Teckentrup supplied the steel doorsets for the project. The requirements for the project were:

500+ doors comprising of: 

  • Front of house doors along platforms, trackside, station bridge and concourse
  • Back of house doors for plant, equipment, air feed turbines and Shafts.

Specifications required characteristics on doors as large as 4.2m x 4m to provide: 

  • 5kPa pressure
  • SR3 security rating
  • E120I290 fire integrity and insulation rating
  • 57dB and 42dB acoustic rating

The delivery.

Planning commenced in 2016 with installations beginning in July of 2017. The project began with the shafts and specialist pressurised ventilation areas. These required pressure, acoustic and fire rated doors that allowed the shafts to maintain the pressures needed to create air flow into the station and tunnels. The doors also had to be capable of withstanding higher pressures in a fire scenario when fan speeds and consequently pressures are greater.

Shafts required doors with two-way 5kPa pressure, fire and acoustic capability. The shafts generate high acoustic levels and to overcome transmission, a twin door solution was developed specifically for the project. Teckentrup’s DW67 door, rated at 57dB was paired with a second Teckentrup T60 door rated at 42dB, 5 kPa pressure in either direction, SR3 security and fire resistance of 120 minutes’ integrity and 60 minutes’ insulation. The size of these doors at 3.2m square was typical of the high specification required. Durward Street shaft took around 100 doors and Cambridge Heath shaft 130. Shafts descend 30 meters and have 6 levels below ground.

Once shaft works were complete the project moved to the other areas – platforms, side tunnels and management buildings. The Group Station Manager's (GSM) building encompasses offices for management and plant and equipment rooms on the lower levels. The building is located just off the platforms and includes 65 doors, many of which are front of house doors and SR3 rated.

As the project completes in 2019, the final stages will see more front of house doors installed, a number with special brass finishes to tie into the architectural finishes of the station.

The key elements.

The key aspects of the project were providing compliant, certified product at large sizes that met the complex specification of pressure, fire, acoustics and security in a single product and the twin door solution development for the extreme acoustic requirements. Overcoming design challenges to achieve the right solution alongside managing the project at such a complex site were further noteworthy achievements.

Jim Rodger, Teckentrup’s Managing Director commented, 

“Our approach is solution driven. Ensuring our products are compliant is clearly a given, however, incorporating the requirements for the use and users of the doors and integrating with the Station’s ecosystem as whole was held as a central objective. Sharing our expertise to bring solutions to the BBMV team has been part of ensuring the success of the project."

Delivering unusual security rated doors for the Tate Modern

The RC4 security rated doors were quite large at 3m x 3m which, combined with the need to clad the doors in the same material as the building, created potential certification issues.
