Crossrail is a 118km railway line along an east-west route across London. Its central section runs via 21km twin-bore tunnels connecting eight underground stations and represents one of the world's largest infrastructure projects. Dr. Sauer & Partners was assigned to provide Category III independent design checking services on the Sprayed Concrete Lining works for the complete Whitechapel and Fisher Street SCL structures. Additional 3D non-linear FEA and assessments were carried out for the wraparound and junction structures of the Liverpool St Station and the Bond St Station.
