The foundation work for the High Speed 2 (HS2) project’s Old Oak Common high-speed railway station in London, UK, has been completed by Balfour Beatty Vinci SYSTRA joint venture (BBVS).
Being constructed with 76,000m³ of concrete and 17,000 tonnes of reinforced steel, this 850m underground station base comprises six platforms for high-speed trains.
Covering 45,000m2, or over six football pitches, the base slab’s deepest point reaches almost 2m thick.
In April 2023 construction was started in with 91 concrete pours to complete the project.
Six underground platforms and services running further north via the existing railway will be the contents of this station following completion, whereas eight surface-level platforms are due to provide interchange to the Great Western Railway, Elizabeth Line, and Heathrow Express.
According to HS2 Old Oak Common project client Peter Gow: “This is the final stage in completing the foundations for the high-speed station, and will be where HS2 tracks are laid, platforms are constructed and the station building and roof and built above.”
The date of finishing the excavation process of the box was summer 2024, and 1.3 million tonnes of London clay removed.
London Concrete, part of the Holcim Group, supplied over 90% of the concrete for the base slab from a dedicated on-site batching plant.
“This latest step will enable us to progress to the next phase of works, with construction of the high-speed platforms already underway,” said BBVS project director Steve O’Sullivan.
While advancing the work on the six HS2 service platforms, wall frameworks being installed for concrete pouring, and also the work is in progress for high-speed platform slabs and construction of the ground floor level.
With the aim of linking the station to the HS2 network, tunneling work is underway by HS2’s London tunnels contractor, Skanska Costain STRABAG JV.
the location of commissioning two giant tunneling machines towards Euston is in the east, while the western team is going to ding using the sprayed concrete lining method.
In order to allowing Elizabeth Line, Great Western Mainline, and Heathrow Express trains to serve the station, Old Oak Common station in West London is being built on former railway depot land.
Additionally, stations are being built at Curzon Street, Interchange, and Euston for HS2,whereas MPB Structures recently concluded a contract to build the substructure foundations for Curzon Street Station in Birmingham.
