The euston contract goes to a joint venture of Mace and Dragados. The Old Oak Common station is being built by Balfour Beatty, Vinci and Systra.
HS2 said the Euston project was currently estimated at £ 1.3 billion and Old Oak Common at just over £ 1 billion.
Costain / Skanska and BAM Nuttall / Ferrovial Agroman were also on the shortlist for Euston, while Mace / Dragados, Bechtel and BAM Nuttall / Ferrovial Agroman were the losing bidders for Old Oak Common.
We are already working on the high-speed train project. More than a thousand people are working in the field in London, paving the way for the start of construction and pre-construction work, including archaeological work.
HS2 CEO Mark Thurston said: "Euston and Old Oak Common are two of the most important elements of the project – two distinctive stations that will help unlock tens of thousands of jobs and new homes in the capital, together with our stations in Birmingham. way we transform travel and set new standards for design, construction and operation. "
Mace and Dragados previously worked together on Battersea Power Station (phase 2), Mumbai International Airport Terminal Two and the Spanish high-speed rail network.
Balfour Beatty and Vinci have collaborated on the TGV Tours-Bordeaux, the Thames Tideway tunnel and the London 2012 Aquatics Center.
Mark Thurston said: "Mace / Dragados and Balfour Beatty / Vinci have a strong track record in delivering some of the world's most challenging and exciting infrastructure projects and I look forward to welcoming them to the London teams."
The new HS2 station at Old Oak Common (pictured above) was designed by a team led by WSP and architect WilkinsonEyre. It will be built on the former Great Western railway depot.
The six 450-meter high HS2 platforms will be built in a 1 km underground box, with twine tunnels that will bring high-speed trains east to the terminus on Euston and west to the outskirts of London. Material that has been excavated during work on the tunnels will be removed by rail from the nearby former depot of Willesden Euroterminal.
HS2 is currently working on clearing the site and preparing the ground (down) before the start of construction, later this year.
This is expected to help launch the UK's largest regeneration project, which aims to transform the former railway and industrial area into a new district with 25,500 new homes.
The underground high-speed platforms are connected to the adjoining conventional station on the ground floor via a shared bridge, which provides connections between HS2 and Elizabeth Line (Crossrail) trains to Heathrow and central London. The design of the station also includes the potential for future services to Wales and the West of England from Old Oak Common. A hall connects both station halves with a roof that is inspired by the industrial heritage of the site.
The long-term planning and development of the broader site is led by the Old Oak & Park Royal Development Corporation of the mayor of London, who plans a mixed-use development with commercial, residential and recreational use.
WSP project director Adrian Tooth said: "In addition to being a catalyst for regeneration in the broader OPDC area, the new HS2 Old Oak Common station will become an important destination with an urban area west of London. function of the station, and recognizes that more than half of the users of the station will switch between the HS2 and the Elizabeth Line underground.The station shape is inspired by our Victorian railway patterns and the juxtaposition of the upper and underground railways.
