A truly collaborative alliance
Clancy Docwra, principal contractor on behalf of UK Power Networks Edison Alliance, appointed Joseph Gallagher ltd to design and build a spur tunnel and connection chamber into an existing 132kV cable tunnel in the Battersea Nine Elms regeneration opportunity area.
Passing close to existing third party rail infrastructure and clean/dirty water assets JGL used extensive, carefully designed and sequenced handworks to construct an underground reinforced concrete junction chamber; under/over and around the existing UK Power Networks tunnel starting from inside the shield used to drive the new tunnel. Automated monitoring removed the risk for surveyors during junction chamber construction. Bespoke internal steel strapping was used to support the existing wedge block cable tunnel during construction of the underground chamber, reducing the risk of existing tunnel movement and potential cable damage.
An existing building was modified to act as acoustic shed as works ran 24hrs for a year.
Positive impact on London
This scheme will provide increased power capacity for the Battersea Nine Elms redevelopment, along with a new electricity substation, which will help distribute power to homes and businesses across the new neighbourhood. Joseph Gallagher is extremely proud to have worked on a project that will breathe new life into a once‐derelict part of London.
