The £570m deal will see Mace Dragados work with HS2 in two stages to finalise the detailed design and then build the Birmingham Curzon Street station.
Mace Dragados beat off competition from rivals Laing O’Rourke and BAM Nuttall in joint venture with Ferrovial.
Mace and Dragados have a strong track record delivering complex infrastructure projects including the refurbishment of Birmingham New Street and Battersea Power Station (phase 2).
They are also working together in a separate joint venture delivering HS2’s London terminus at Euston.
HS2 Ltd’s Chief Executive, Mark Thurston said: “Birmingham Curzon Street is right at the heart of the HS2 project, providing a fantastic terminus for trains running right into the heart of the city centre.
“The station will play a vital role in the long-term economic future of the West Midlands, creating hundreds of jobs during construction and boosting the region after the pandemic.
“Mace and Dragados have some incredible experience delivering some of the world’s most challenging and exciting infrastructure projects, and I look forward to welcoming them to the team.”
Andy Street, the Mayor of the West Midlands, added: “Not only is this a major shot in the arm for our region’s construction sector that was performing so well pre-Covid, but the building of Curzon Street is also set to create hundreds of jobs.
“That’s local jobs for local people at such a difficult time, and I will ensure we continue to run construction training courses so residents can get the skills they need to take on these new roles.”
HS2 worked with WSP and Grimshaw Architects LLP on the design for Curzon Street, which is inspired by the great arched roofs built by the Victorian railway pioneers.
Significant progress has already been made on site at Curzon Street. Site clearance is now complete and a massive archaeological programme, involving 70 archaeologists, has unearthed the world’s oldest railway roundhouse.
