London Rail special: Whitechapel station design changes generate 15% cost saving for Crossrail

Design changes have generated savings of 15% on Crossrail’s Whitechapel station project, according to the project team.

Consultant Hyder major projects director Nigel Hayward told NCE’s London Rail Conference 2013 that moving away from the original design to one that used closer integration with London Overground and London Underground had created cost savings and a more compact station.

“Most of these savings were due to reduced excavation,” he said.

“Design decisions we made, such as putting the station concourse above ground, massively reduced the amount of excavation that was needed.”

The more compact design reduces the distance from the street to Crossrail platforms by 70m, and also means that the ground-level concourse maximises the amount of time passengers spend in daylight.

“Making the station smaller was another key part of reducing the cost.” said Hayward. “If the station is smaller, less construction needs to be done. We have also reduced the risk of settlement which helps working around London Underground tunnels.”

Whitechapel station is a unique challenge because of its location in a densely built up area, he added. The station will be an interchange between London Underground’s Hammersmith & City Line, the East London Line section of the Overground and Crossrail.
