HS2 Ltd has awarded the Skanska, Costain and Strabag joint venture (SCS JV) an additional £78m for its role in delivering the approach tunnels into Euston station.
The total contact is valued at £1.2bn and the additional funding is within contingencies already set aside in HS2’s £44.6bn phase one budget.
The SCS JV’s remit involves the design and construction of major tunnels in the approach to the London terminus at Euston station.
A Skanska spokesperson said the additional funding “relates to planned and agreed changes to the scope of works under the contract”.
They added: “Since being given notice to proceed by HS2 Ltd in April 2020, significant progress has been made on the project.
“This includes major earthworks, operations to assemble the first tunnel-boring machine (TBM) for launch this summer and the building of major structures, such as a new rail-transportation logistics hub that will remove one million lorry journeys from London’s roads. In total 3,500 people are currently working on this section of the project.”
A spokesperson for HS2 Ltd said: “There has been no increase in the budget for phase one of HS2. The revision of budget allocation was anticipated spend and is all covered within the phase one budget.”
Construction News understands that detailed designs for the Euston tunnels are now all but complete and will be unveiled in the coming weeks.
Euston Tunnel will carry passengers between London Euston Station and Old Oak Common Station on the HS2 network. Euston tunnel will be bored using TBMs launched from the western entrance, near Old Oak Common Station.
The tunnel will be 7.2km long, and at its deepest point it will run 50m below ground.
Earlier this year, HS2 revealed revised designs for its Euston terminus after the Department for Transport took the decision to scale back the station from 11 platforms to 10.
