Skanska is planning to use 3D-printed concrete in its work on HS2, a high-speed rail system reported to cost as much as $147 billion, under construction in the U.K. 

The joint venture between Skanska, U.K. civil contractor Costain and Austrian contractor Strabag will employ a technology called “Printfrastructure” that will print concrete structures on site instead of shipping them in prefabricated slabs or mixing and pouring it at the location. 

The machine is also capable of going into physically restricting spaces, removing the costs of sending people in to do the same job. Proof-of-concept trials are due to begin next spring, according to an HS2 press release.
