With London’s population growing year on year and being set to hit 10 million by 2030, the demands placed on London’s ageing underground network continue to increase.
With our joint venture partner CPC Project Services, we are transforming four of the oldest sections of the London Underground network - the Circle, District, Hammersmith & City and Metropolitan lines. Works include the installation of 51 new signalling rooms and a variety of other upgrades along 161km of track to enable the introduction of new train rolling stock. At the heart of the programme is the installation of a brand new £800m CBTC signalling system, which will allow new rolling stock to run more frequently and faster.
Our role covers two areas, firstly we are reviewing and improving the existing major programme, which has over 4,000 interfaces with other works, to make it more integrated, efficient and value driven. Secondly, we are embedded with Transport for London’s (TfL) client team working on the implementation of the programme and delivering projects on their behalf.
