Barhale is set to expand its contribution at HS2’s London terminus after receiving approval for further utilities infrastructure works from HS2’s Station Construction Partner, HS2 (Mace Dragados JV). The package builds on Barhale’s earlier phases at Euston and will continue the multi-utility corridor around the southern side of the station before reconnecting to existing networks.
Scope of the new programme
- Fresh water: design and build of approximately 210 metres of 1000 mm (42″) and 360 metres of 250 mm diversions
- Foul water: around 220 metres of 1500 mm sewer diversion
- Gas: about 190 metres of 800 mm (36″) gas main diversion
- Electric & comms: circa 180 metres of new high-voltage and 90 metres of communications cables
- Additional localised facilitating diversions of secondary services
The southern section routes past the existing mainline station and through Euston Square. Works will require careful sequencing at the Euston Road crossing to maintain traffic access while delivering the 1000 mm water diversion.
Experience from previous phases
Barhale will draw on experience from earlier Euston utilities packages—delivered with the principal utility owners (including Thames Water, Cadent and London Underground Limited)—and on its established collaboration with Mace Dragados. The contractor continues enabling activities along Hampstead Road, Cardington Street and at Cumberland Market, alongside the critical Southern Tie-in, as part of HS2’s staged utilities programme at Euston.
Programme timeline
Design is expected to begin before the end of summer 2025, with construction targeted to start in March 2026 and complete in early 2029.
