COWI in the UK has won the detailed design package contract for utility works around the proposed HS2 station at Euston with construction partners Mace  Dragados Joint Venture.  

This vital design package will facilitate HS2’s works to improve connectivity and capacity for passengers accessing the existing London Underground network in  the area. This includes realigning utilities to create space for a brand-new London Underground ticket hall with direct connections to Euston Square station  and rom the new HS2 Station. For the first time, tube passengers will have  seamless connections between the Northern, Victoria, Circle, Hammersmith and  City and Metropolitan Lines at Euston.  

Design scope is due to complete in quarter three of 2023, with utility construction works due to be carried out until the late 2020s. 

The detailed design of utility diversions to the southern section of HS2 Euston  Station includes significant, critical utilities for Thames Water Utilities Ltd;  CADENT; multiple telecom companies; UKPN. The major utilities comprise a 1500mm dia sewer diversion; multiple large Water Main diversions; large Gas  Main diversions; critical fibre optic telecoms diversions and High, & Low Voltage

electricity cable diversions. In addition, COWI in the UK will provide design of the  service connections into the new HS2 Euston Station. 

The new HS2 station will create a new space for Euston and London, with a  300m long publicly accessible station hall, opening out onto two new public  spaces to the north and the south, activated by retail and station facilities under  a new top-lit station roof. 

Andy Sloan, Managing Director, COWI in the UK, said: “HS2 is one of the UK’s  most ambitious transport schemes ever to be undertaken, with Euston station  known for being the most complex utility project in the UK, and so we are very  proud to be part of it and welcome the opportunity to show how extensive  COWI’s skills and expertise are.” 

The ten-platform station, which will form the London terminus of the HS2 route,  will be delivered by Mace Dragados Joint Venture as a single-phase build. This  will result in a more efficient construction process and provide better alignment  to local surroundings and proposed oversite development compared to earlier plans for an 11-platform design.
