Crossrail tunnelling, Belfast

About this event

Crossrail is a major new railway which runs from east to west through central London, improving connections and reducing journey times to airports, the City of London, Canary Wharf and surrounding areas. Key features of the project are listed below:

  • Five twin bored tunnelling drives under central London;
  • Eight new underground stations, portals, shafts and crossovers;
  • Complex interfaces and connections with London Underground, Network Rail, Docklands Light Rail, Thames Water and other third parties.
  • Heritage and environmental issues related to construction in close proximity to historic structures.
  • Public realm, regeneration and environmental development opportunities.

The Client is Crossrail Ltd, a subsidiary of Transport for London (TfL.) Funding for the £14.8 billion project is sourced from Transport for London, Department for Transport, and private investment.

Please note that catering is from 17:30, with a lecture start at 18:15.

Alison Norrish, Director, Arup (London)

Alison led the multi-disciplinary team responsible for the design of Crossrail tunnel drives between Farringdon and the portals to the east of the central underground section. The team included tunnel, geotechnical, structural and specialist engineers who delivered the designs supporting tenders for about £1bn contract value and subsequently the detailed RIBA F drawings for construction.

The commission included all ground movement predictions and impact assessments of buildings, structures, tunnels, utilities and required the management of multiple interfaces with other designers and third parties. Alison lead the development of strategies and methodologies for the assessment of the impact of the works on existing structures and assets, which is the major project risk as the tunnels pass through the centre of London.
