2009-2018. Victoria Underground Station Upgrade, London, UK
Victoria underground station is at the heart of London’s transport network and is one of the busiest and most congested stations, used by around 100 million passengers each year. Over the years numerous improvements are carried out in the Victoria Station Upgrade (VSU).
Major works include:
- A new underground north ticket hall at the junction of Bressenden Place and Victoria Street, with an entrance at street level
- Doubling in size of the existing Victoria line ticket hall (south ticket hall)
- 400m of new interchange tunnels, connecting the south and north ticket halls and the District & Circle line platforms
- Full modernisation of the existing station areas including nine new escalators and seven new lifts to provide step free access between street, ticket hall and Victoria line platform levels
- Improved access and new lifts between the National Rail and Victoria line platforms and between the Victoria line and District and Circle lines platforms
Close proximity to an urban environment meant the interaction between the jet grouting with existing basements, foundations, utilities and tube tunnels needed a robust monitoring system. The surrounding buildings were closely monitored using Robotic Total Stations (RTS), prisms and back-up manual monitoring. Below ground saw the installation of precise liquid-levelling cells in a number of building basements, accurately monitoring vertical movement in near real-time during the critical stages of the project. The Profound Liquid Levelling Sensors (LLS) were linked with an IS-module including internet connection to send data into the web based online monitoring software including alarm through SMS and email, and automatic PDF reports.
