London Underground has signed up seventeen contractors to overhaul the 151-year old tube networks’ power lines and supplies routes.
A host of firms including Balfour Beatty Engineering Services, Clancy Dowcra, McNicholas, J Murphy & Sons and C Spencer will join other specialist electrical contractors on two eight-year frameworks.
Worth up to £250m, the two frameworks will run concurrently in what London Underground’s director of major programmes David Hughes described as the “biggest programme of Tube modernisation ever seen”.
The zero-value contracts, so-called because there is no cast-iron guarantee of work, involve the design, installation and commissioning of a high voltage substation and 11kv and 22kv cable routing.
