As a special<strong>is</strong>t for the design & construction of metro projects, we are active in countries all<br />
over the world. After successful completion of Singapore Metro Circle Line, C852 & C855 and<br />
Metro Delhi AMEL C1 & C6, we are currently working on the € 340 million project Downtown<br />

King’s Cross Station Redevelopment<br />
The purpose of th<strong>is</strong> metro project in Central London was the connection of ex<strong>is</strong>ting metrolines<br />
and St. Pancras Station (King’s Cross). A complex subterranean construction was<br />
necessary, i.e. pedestrian tunnels, stair and escalator shafts and vertical shafts. LaserShell™<br />
method in conjunction with the TunnelBeamer™ real-time surveying package was used as,<br />
tunnelling system for the London clay. We have also recently been awarded the € 280 million<br />
contract C510, Whitechapel and Liverpool Street Station Tunnels, as part of the Crossrail<br />
project.<br />
Metro Project ‘Stadtbahntunnel’ Karlsruhe<br />
The works for the inner city ‘Stadtbahntunnel’ Karlsruhe have already commenced and the<br />

underground metro stations. A similar project in confined space was the inner city lot 306 of<br />
the metro Rhine-Ruhr-Bochum.<br />
C855: Slurry TBM meets the challenging geology<br />
of extremely fine and soft ground, weathered rock<br />
and exceptionally strong granite.<br />
