The HS2 project consists in the construction of a high-speed railway line linking London to Birmingham (phase 1) and then to Manchester and Leeds (phase 2) in the North of England.
Phase 1 of the project, which is currently underway, involves a 200-km section between London and Birmingham. It has been divided into 7 work packages that have been allocated to several consortia.
Two of these work packages were awarded to Eiffage-Kier, which entrusted the DJV composed of Setec, Arcadis and Cowi to perform the design of the C2 and C3 central work packages, which cover a distance of 80 km, including 17 viaducts, 3 cut-and-covers, and major earthworks (high embankments up to 14 m high, and cuttings nearly 30 m deep).
TERRASOL is part of the SETEC team on the project platform in Birmingham.
This multidisciplinary team is involved in the earthworks studies for both the C2 and C3 work packages: geotechnical studies, drainage, environment, landscaping, BIM, etc.).
