Crossrail Farringdon Tunnelling Progress Thank you very much for your patience whilst we continue with tunnelling work as part of the new Crossrail Farringdon station. Four out of the eight Tunnel Boring Machines on the entire Crossrail project end their journeys at Farringdon. Phyllis and Ada have already completed their tunnelling. Victoria and Elizabeth, will be tunnelling from Whitechapel, arriving in early 2015. This will not only mark the end of their journeys, but also the end of Crossrail’s tunnelling. Crossrail Tunnels: Look Ahead The Sprayed Concrete Lining (SCL) tunnelling works at Farringdon are progressing well. Over the next few months we will continue with the enlargement of the running tunnels into both platform tunnels as well as creating cross passages - the interconnecting tunnels enabling pedestrian access to and from the platforms. Tunnelling activity is currently taking place from under Cowcross Street, and will progress under the south end of St John Street. It will continue towards Charterhouse Street and then to Crossrail Farringdon’s eastern ticket hall. Secondary lining of the tunnels will commence at the western ticket hall and progress towards the eastern ticket hall from early 2015. Secondary lining provides further reinforcement and strength to the existing tunnels. Continual monitoring of the properties above the tunnels is being carried out using prisms and other monitoring equipment fitted to buildings. Grout shafts have been constructed to give further protection to buildings by pumping liquid grout through the ground to stabilise any ground movement if detected. We do not expect there to be any damage caused by the tunnelling, but for further information please visit our website http://www.crossrail.co.uk/construction/managing-the-effectsof-construction/ground-settlement-managing-the-effects-oftunnelling

Duration of work • Tunnelling is taking place 24 hours a day, 7 days a week
What to expect • Unlikely to notice the passing of the Tunnel Boring Machine • Victoria & Elizabeth will arrive at the Farringdon eastern ticket hall in early 2015
What we will do • Carry out real time monitoring and install extra monitoring equipment in properties where necessary • To mitigate the impacts of ground borne noise throughout the SCL tunnelling works, we will ensure ‘Best Practicable Means’ is employed at all times • Plant and equipment will be continually reviewed
• Investigate any concerns of property owners if they are being affected by the tunnelling
