Fast track for Britain’s future

HS2 is critical for the UK’s low-carbon transport future, providing rail capacity, and helping rebalance the economy.

The Skanska, Costain and STRABAG (SCS) joint venture (JV) brings together an industry-leading combination of tried, tested and successful partnerships, world-wide high-speed rail experience and extensive national and regional knowledge.


About the JV

HS2 is a state-of-the-art, high-speed line critical for the UK’s low carbon transport future. It will provide much-needed rail capacity across the country, and is integral to rail projects in the North and Midlands – helping rebalance the UK economy.

Skanska Costain STRABAG Joint Venture (SCS JV) are working together to deliver HS2 along the final 26.4km of HS2’s journey to its southern terminus in Euston. The JV will complete challenging works taking the railway from Northolt to Euston via Old Oak Common, building a variety of structures requiring expert precision and care. As 95% (21km) of the route will be in tunnel, SCS will be running seven tunnel boring machines (TBMs), of which five will operate simultaneously.

Our experience

Not only have the individual companies delivered high speed rail, major infrastructure and some of the most iconic structures internationally, the joint venture also has a proven record of working together.

Skanska and Costain have a long history of successfully delivering civil engineering projects together in the UK, dating back 30 years. In joint venture they have delivered many major infrastructure projects, including the M25 in the 1980s, High Speed 1 in the early 2000s and the current Crossrail endeavour coming to completion under the streets of London in 2018.

STRABAG and Skanska have worked together for over 15 years on European projects in Switzerland, Slovakia and Norway.
