Civil engineering, infrastructure and tunnelling specialist Barhale will undertake an extensive schedule of utilities infrastructure works to continue the multi-utility corridor constructed during the first phase of works around the northern section of the site. The new works will extend around the south of Euston station before reintegrating with the existing utility networks.
The programme will form a part of the complex enabling and diversionary works at Euston. Barhale will design and build 210m of 1000mm diameter and 360m of 250mm diameter fresh water diversions; 220m of 1500mm diameter foul water sewer diversion; 190m of 800mm gas main diversion; 180m of new high voltage and 90m of communications cables; and multiple localised facilitating diversions of secondary services.
Barhale senior contracts manager Mike Faherty said the service corridor passed around the front of the existing mainline train station, through Euston Square.
“While this southern leg will present us with shorter chainage than on previous phases of the project, we are working in and around what is arguably one of the busiest parts of London,” he said. “For example, we face the challenge of negotiating an exceptionally complex interface, including the crossing of Euston Road with the 1000mm water diversion, while maintaining suitable access for traffic at all times.
“We will be drawing on the experience of the conditions gained on the previous phases of this project and on our close working relationship with the principal utility owners Thames Water, Cadent and LUL, to ensure that we again deliver a first-class result to pave the way for the new HS2 station’s construction.”
Barhale also continues to deliver enabling works through Hampstead Road, Cardington Street and at Cumberland Market along with the critical Southern Tie-in.
Faherty added that this final major package of utilities works was a key piece of the jigsaw in preparing Euston for HS2, and the whole team was proud to be playing a part.
Design work for the utilities programme is expected to start soon and construction to be under way from March 2026. Completion is expected in early 2029.
