Value Est. £300m
The Bond Street Station Upgrade project has provided much-enhanced capacity at this key transport interchange in the heart of London. The station upgrade included a new Ticket Hall opening on to Marylebone Lane and a new escalator and passageway to the north end of the Jubilee line platform. A new Step Free Access (SFA) route of lifts and passageways to all platforms and a new congestion relief passageway between the Jubilee line and the Central line were also incorporated. The Project included works for Crossrail, Cooling the Tube and development of the frame for the new Over Site Development (OSD) building on 354-358 Oxford Street; demolished to make a working site.
Engineering challenges included the top-down construction of the ticket hall structure which replaced the basement of a Listed Building constructed in the 1790s, and demolition of a former bank building built in the 1960’s to provide access to the shafts and tunnels which form the new passages and escalator shaft providing improved access to the platforms.
LBA initially worked with Costain/Laing O’Rourke during the tender period for the project providing construction, Planning and Instrumentation and Monitoring advice. Once the contract was awarded, during the pre-construction phase, LBA provided;
• Ongoing Construction advice,
• Programme support,
• Instrumentation and Monitoring advice,
• Interface Management with London Underground.
These roles continued into the main construction period, with changed emphasis as the project advanced to include;
• Tunnel Engineering management,
• Station Interface management, planning possessions and closures,
• Surveying and Monitoring management,
• Provision of SCL shift engineers to manage the site works,
• Requirements and Handover management.
- Tunnel Engineering management of all the tunnel processes and complex temporary works designs, including setting up the Emergency Preparedness Plans.
- Instrumentation and monitoring management, providing clarity in interpretation of results and confidence to the project team and Client.
- Introduction of Amberg tunnel software to enable the complex SCL tunnels to be built with maximum efficiency.
