Crossrail station profile: Liverpool Street

Crossrail’s Liverpool Street station will serve the City of London and provide interchanges with London Underground’s Northern, Central, Metropolitan, Circle and Hammersmith & City Lines, connections to Stansted airport and National Rail services at Liverpool Street and Moorgate stations.

It will be located below London Underground’s (LU) existing Liverpool Street and Moorgate stations with both stations providing access to the Crossrail station.

At the eastern end of the Crossrail station, a new integrated ticket hall will be constructed beneath Liverpool Street close to the Broadgate development. The new ticket hall will provide step-free access from street level to the new Crossrail platforms. Nearby, a 40m-deep box structure will be located on Blomfield Street to accommodate ventilation, electrical, mechanical and systems equipment.

At the western end, a further new ticket hall will be built by developing the existing Moorgate station ticket hall. The development in which this is housed also contains a 33m-deep draught relief shaft, which has already been built in its lower basement to aid the Crossrail development.

A section of Finsbury Circus will be temporarily acquired during the construction of Crossrail’s Liverpool Street station. The majority of the site is currently used by a bowling club, which will be relocated during construction.

Key facts

  • Serves the City of London financial business area
  • The new Crossrail station links together two existing London Underground (LU) stations on the Metropolitan & Circle Lines, namely Liverpool Street station at the east end and Moorgate at the west end.
  • In addition to connections to existing LU ticket halls, new Crossrail station entrances and ticket halls will be provided at both Liverpool Street and Moorgate.
  • At Moorgate, a permanent shaft will house station ventilation systems, lifts and escalators. The shaft is 33m deep with an internal diameter of 32m.

 

“We need the site for two purposes,” says Crossrail Central project manager for Liverpool Street Hani Rizkallah. “First, to enable construction of the platform tunnels via a temporary construction shaft and second, to accommodate construction facilities including site offices. Following completion of the works, Finsbury Circus will be restored to its original condition.”

“At the eastern end of the Crossrail station, significant enabling works are required to relocate existing LU assets to create the space for new Crossrail infrastructure,” explains Rizkallah. “We are working closely with LU to ensure that we keep its assets operational throughout our work, and of course keep to our construction schedule.”

This work will involve constructing a replacement Connect Core Communications Equipment Room (CER) for LU, a Powerlink substation, various switch rooms and carrying out a number of railway utility diversions.

When the CER relocation is complete, space will become available to begin a complex series of public utility diversions from the roadway in Liverpool Street into a newly built utility corridor. This will allow open cut construction of the new Broadgate ticket hall at the eastern end of the Crossrail station. Similarly, public utilities will be diverted at the western end.

As with other Crossrail stations, the platform tunnels, escalator shafts and underground passageways will be constructed using sprayed concrete lining (SCL). A dedicated SCL design team has been mobilised on the project to standardise the approach to using this specialist discipline. The connection between Crossrail and LU’s Northern Line at Moorgate involves a particularly challenging SCL stairway construction directly beneath an existing escalator, at deep level, adjacent to the Northern Line platforms. The design team is working closely with LU and industry experts to develop a safe construction method that minimises disruption to rail passengers.

Delivering a complex programme of advanced works is one of the most significant early challenges at Liverpool Street. This will enable main construction contractors to break ground in 2011 when two contracts for diaphragm wall/piling, and shaft construction/SCL are set to mobilise.
