Our work in detail

More than a tunnelling project. Discover more about our work, above and below ground.

'The beating heart of HS2 in London'

It's what our Logistics Hub in west London has been called. It's a vital cog in the operation that is helping to minimise local disruption while supporting delivery of the project in a smarter, more responsible way.

A lasting legacy

Before starting work as the SCS joint venture, we completed two major enabling works contracts. Our specialist piling, ground engineering and steel fabrications team, Cementation Skanska, has also played a key role in delivering HS2 works in London.
