Crossrail has completed work on the Fisher Street shaft in Holborn.
Crossrail’s western tunnels contractor BAM, Ferrovial, Kier (BFK) and their subcontractor Barhale, has been excavating and lining a 15-metre diameter emergency access shaft in Holborn.
Initially, the shaft will support tunnelling works on a crossover tunnel below Red Lion Square. Once complete it will be used for access and ventilation to the Crossrail tunnels.
Construction work has been completed nine months ahead of the original schedule due to ‘re-sequencing’ of works on the project.
Crossrail worked with UK Power Networks to relocate electricity substation equipment, a requirement before tunnel boring machines Phyllis and Ada could pass under Holborn on their journey between Royal Oak and Farringdon.
Roger Mears, Crossrail construction manager, said: “These works are key to Crossrail’s success in the Holborn area, and the completion of the excavation and structural lining of the Fisher Street shaft is another milestone in our western tunnels project.”
Last month Camden Council approved Crossrail plans to develop 30,000 square feet of residential space above the shaft.
