LONDON UNDERGROUND
Craig Prangley, project director of the Taylor Woodrow/BAM Nuttall joint venture, and Glenn Keelan, programme manager at London Underground, give an update on the Victoria Station Upgrade project.
F
our years into London Underground’s £700m Victoria Station Upgrade project,
the Taylor Woodrow/BAM Nuttall joint venture (TWBN) is making significant progress in providing a refurbished extended Underground station with improved and new ticket halls.
As part of the project, a new North ticket hall at the junction of Bressenden Place and Victoria Street with eight new lifts and nine new additional escalators and links to the Victoria Line and District and Circle Lines is expected to significantly increase station capacity and make it step-free.
Craig Prangley, project director of TWBN, which was awarded the contract in 2010, told RTM that over the last few years the key to enabling the work around Victoria has been in

solving the logistical challenges.
“The sheer number of people that flow through the Victoria area each morning, which is now approaching 100,000,
requires
our works to be carefully planned to ensure they can safely reach their final destinations without undue delay and disruption.”
A key measure the JV partners implemented revolved around ‘traffic phasing’ moves that required the team to carry out and complete activities in order to facilitate the next part of the works. In particular, it set up a Strategic Working Group with London Underground and Transport for London to co-ordinate how to develop the scheme while moving traffic around safely. All the project partners have stated how important this collaborative approach has been in facilitating the upgrade.
“Logistics have been a challenge since the day we arrived on site in May 2010, and are still with us today,” said Prangley. “It’s just we understand them now in far more detail and we are able to manage them very closely with our colleagues and the teams that work around the station.”
Glenn Keelan, programme manager at London Underground, stated that as well as tackling the logistical challenges, much wider progress has been made on the upgrade.

“If we look at the slightly larger operation, the progress made on the excavation and the piling in the two main ticket halls has been really encouraging,” he said. “There has been a fair amount of effort put in to overcome the logistical challenges in order to keep the work on track. And now it is really encouraging to see how work is expanding on a week-by-week basis.”
Tunnelling
One area where significant progress has been made is in delivering the new tunnels, which will range from 4.5m-9m in diameter. For instance, works are progressing well on the construction of the Paid Area Link (PAL) 10 escalator tunnel, which is located behind the Victoria Palace Theatre.
The tunnel decline is complete and the JV team is moving onto the construction of the cross- passages that will connect the tunnel to the station, whilst ground treatment works are now
