National Grid has agreed a six-year contract with HOCHTIEF-MURPHY Joint Venture (HMJV) to deliver the tunnelling and shaft work of the second phase of its London Power Tunnels (LPT2) project in a contract worth around £400m.
Work is scheduled to start in March next year. The £1bn, eight-year project will see the construction of a 32.5km tunnel which will house electricity transmission cables 30m underground. The new cables will replace three circuits that currently run under the surface of roads between Wimbledon in the southwest to Crayford in the southeast.
