As part of Transport for London's (TfL's) multi-billion pound investment programme to improve and expand the transport network, the Bond Street Station Upgrade (BSSU) project will provide approximately 30% more capacity. The upgrade work will result in fewer delays, less congestion, step-free access and quicker journeys for customers in and out of the station. The brand new ticket hall, currently under construction beneath Marylebone Lane, will open in 2017.
Alan Auld Engineering Ltd (AAE), was appointed by Costain Laing O’Rourke JV (CoLOR) to design and detail both the temporary ground support and support to the existing LU assets. AAE worked closely with the CoLOR construction team to develop a safe system of work, that ensured minimal impact on the LUL operation railway, whilst optimising the excavation times. The final solution resulted in a minimal amount of propping within the platform tunnels.
A traditional system of timber and steel supports was utilsed to allow sequential excavation and support of the ground both below and between the existing LU platform tunnels.
The success of the BSSU project was recognised through London Underground winning the prestigious Global Tunnelling Project of the Year (under $500m) Award at the 2015 New Civil Engineer International Tunnelling and Underground Space Awards.
