Hosted by broadcaster, former Tomorrow’s World presenter, Maggie Philbin, the awards saw the Nine Elms South Bank Cable Tunnel, by Joseph Gallagher, win London Infrastructure Project of the Year. The complex project was constructed in close proximity to rail lines and utilities, and carefully designed to complete an underground reinforced concrete junction chamber.
Clancy Docwra, principal contractor on behalf of UK Power Networks Edison Alliance, appointed Joseph Gallagher 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 Joseph Gallagher 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, while an existing building was modified to act as acoustic shed as works ran 24hrs for a year.
