Tunnelling Project Award for Joseph Gallagher

Following a rigorous live judging process, Joseph Gallagher emerged as the winner of Tunnelling Project of the Year (Under $100 Million) for their work on Nine Elms Southbank Cable Tunnel.

In a glittering ceremony held at the Grange Tower Bridge Hotel, London on 6 December, individuals and organisations across the geo-tech industry were honoured across 14 categories in a night of recognition dedicated to celebrating exceptional achievement. The Tunnelling Festival brought together the New Civil Engineer Tunnelling Summit and Tunnelling Awards participants into one exciting event.

The judges praised the project for how this critical piece of infrastructure used a modern application of traditional tunnelling techniques and without impact to sensitive third parties. The local community were well engaged, and the project exceeded client’s expectations.

Tunnelling Project Overview

Clancy Docwra, principal contractor on behalf of UK Power Networks, 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. This tunnelling project 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. And a 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. Enhancing local relations, an existing building was modified to act as acoustic shed allowing works to run 24hrs for a year, with no complaints from the community.

“I am incredibly proud of this award, I put my heart and soul into this tunnelling project. For Joseph Gallagher, it is well earned recognition of just one of the many exciting and technically complex projects we deliver every day.”

Joseph Gallagher operate a behavioural safety programme known as Living Incident Free Everyday (LIFE). It is a way of going to work that puts safety at the top of the agenda and is at the core of everything Joseph Gallagher does. The final total was 118,110 injury-free man hours worked on the project.

This continues a year of great success for the project team of UK Power Networks, Clancy Docwra COWI and Joseph Gallagher. The project received an ICE London Civil Engineering Award in May, for Best Infrastructure Project and a United Kingdom Society of Trenchless Technology Award in September for New Installation Award Energy & Communications. This award was for demonstrating a key role in successful new installations of cables, ducts or pipelines using trenchless techniques.
