Realistic Simulation Supports Expansion of the London Underground

Dubbed “one of the most complex tunneling projects in the U.K.,” the Bond Street Station Upgrade (BSSU) project is being carried out to satisfy growing traffic demands within London’s busiest shopping district, the West End.

Upon its completion, Bond Street Station’s daily passenger numbers are expected to rise from 155,000 to 225,000.

A project this complex in nature has to consider the existing tunnel infrastructure, as well as the stress and strains imposed by the surrounding soil layers for the development of new tunnels.

Dr. Sauer and Partners was contracted to provide such tunneling expertise. The company took on responsibility for preliminary-to-detailed design and

Using FEA simulation, they were able to virtually test the ground through which the tunnels are being dug alongside the existing tunnel structures.

This realistic assessment enabled them to improve upon the preliminary design, as well as bring greater confidence to the overall approval process.
