London Underground Limited (LUL) Bond Street Station Upgrade project (BSSU) is a large, complex, urban infrastructure project delivered in a location with numerous site constraints (construction activity on and around Oxford Street, Europe’s busiest street), and a significant number of influential and sensitive stakeholders.
Bond Street station currently suffers from significant levels of congestion caused by heavy demand, poor access for mobility impaired passengers and restricted capacity on access to and from the Jubilee line platforms. The project brief was to upgrade the station in order to relieve congestion to a very busy and crowded station and to provide step free access. This was achieved by providing a new station entrance and satellite ticket hall on the north side of Oxford Street, a new route to the Jubilee Line with improved interchange between the lines, new lifts and escalators, connections to existing LUL infrastructure and a direct connection to the new Crossrail Bond Street station.
Atkins has been involved with the project since 2007 and has provided a multidiscipline design service with lead designers for the tunnelling, architectural, station planning and mechanical, electrical and public health (MEP) design elements.
The project’s scheme design (RIBA Stages C and D) was initially developed by Atkins under a direct appointment with LUL. After competitive tendering, LUL subsequently awarded the design and build contract to Costain Laing O’Rourke Joint Venture (CoLOR) with the Halcrow Atkins Joint Venture (HAT) as their lead designer for completion of the detailed design (RIBA Stages E and F).
Tunnelling works comprise the construction of new lift shafts, an inclined escalator barrel, station passage and concourse tunnels and stairs. The majority of the tunnelling works has been carried using sprayed concrete linings (SCL). Traditional squareworks (non-SCL) to form passages, stairs and lift shaft was used where space constraints from the very close proximity of the tunnelling to the existing station structures prevented the use of SCL. New overbridges over the Central and Jubilee Line platform tunnels were constructed in either squareworks or a hybrid SCL and squareworks design.
From 2013 Atkins has provided an on-going role with technical support to the contractor during construction. Completion of the construction works is due in 2017.
