Key projects

Manchester Metrolink

Laing O’Rourke, VolkerRail and Thales secured the initial Phase 3 project (to treble the size of Manchester Metrolink) in 2008. Working as a consortium, they then went on to secure further works, which were undertaken over the course of a 12-year delivery period.

Northern Line extension

Working with Ferrovial Construction as part of the FLO joint venture, Laing O’Rourke delivered the first tube network extension in over a century.

The £825 million project saw the Northern Line’s Charing Cross branch extended from Kennington to a new terminus station at Battersea Power Station, with a new intermediate station built at Nine Elms.
