AtkinsRéalis provided full engineering and geotechnical consultancy services for the project management, design and supervision of the construction of a 260m long service tunnel beneath the River Liffey in Dublin City Centre.

The project consists of a 260m long, 3m external diameter tunnel traversing under the river Liffey near Ringsend in Dublin. It also includes the construction of an 8m external diameter reception shaft on the north campshire of the river. The tunnel will be used to house the services necessary for the current and future developments at Dublin Docklands. The tunnel was constructed using the pipe jacking method with a slurry shield Tunnel Boring Machine. The reception shaft consists of secant piles with a reinforced concrete ring-beam and a shotcrete lining. AtkinsRéalis also provided full time site supervision on the project throughout the construction process monitoring works, progress and costs on the project.
