Northern Ireland-based tunnelling specialist Terra Solutions has been awarded a contract by Hochtief to construct new pedestrian tunnels between Bloomberg’s new office in London and Bank Station.
Work on building the two tunnels from the Bloomberg’s new European Headquarters on Cannon Street in London is expected to start this month.
The sprayed concreted lined (SCL) tunnels will provide a direct link from the station to the office, which will house a new ticket hall. The tunnels will be constructed using the new “strong-back method”, which Terra Solutions has said has only previously been used in the UK on Victoria Station. The SCL will form the primary lining with a cast insitu concrete secondary lining installed later.
The tunnels are expected to be completed by summer next year when the Bloomberg’s new office, which celebrated topping out last week, is expected to be nearing completion.
“In order to reduce peak period congestion on the Waterloo and City line at Bank Station, Transport for London has reached an agreement with the developer of Bloomberg Place to construct a new ticket hall within its basement, providing an entrance/exit,” said Terra Solutions managing director Barry McAllister. “These new passenger entrances will be formed by two 5.5m diameter tunnels.”
Terra Solutions said that it has worked with Ulster Bank to finance the project. Ulster Bank is providing us with increased facilities to help us meet the investment needed to complete such a major contract,” said McAllister.
