Victoria Station Upgrade (VSU)

Victoria, London, UK · 2010–2019 · £700 million (2019 prices)

The judgement call

Account-gated at launch

* Use of NEC3 contracts (ECC Option C and PSC) to promote collaborative working and manage risks effectively. * Co-location of all project team members from the beginning to enhance relationships and foster a "best for project" ethos. * Innovative construction techniques, such as installing a unique system of needles to underpin existing District and Circle lines during underpass construction, allowing trains to continue running. * Effective use of early warnings and risk-reduction meetings to mitigate impacts of unexpected ground obstructions and redundant services.

Key engineering challenges

* Carrying out works in a highly congested urban environment while keeping the station operational for up to 300,000 daily users. * Excavating new access tunnels in fast-moving gravels and sands, less than 30cm from the Victoria line and 60cm from District and Circle lines. * Managing complex ground conditions and protecting nearby operational assets. * Minimizing impact on local stakeholders in a densely populated urban environment.
