EXO Building

EXO Building

The EXO Building, adjacent to Dublin’s 3Arena, will be Dublin’s tallest office building with 15 floors and standing at approximately 73m. One of the main architectural features of the development is the three cores exposed at ground level, creating the appearance of the building being suspended in mid-air. During construction of the superstructure, the EXO truss spanning between the three cores will be supported by temporary towers around the perimeter of the building.

Our Role

Our Role

ByrneLooby designed the CFA piles for the permanent superstructure beneath the three cores, and the piling to support the temporary works needed to ensure stability during construction. The foundation pile loadings for the scheme were up to 4,500kN which in Dublin would generally suggest rock socketed piles are necessary. Through a preliminary pile load testing regime, and based on our substantial experience in the area, ByrneLooby justified the used of 900mm diameter CFA piles embedded into the underlying boulder clay, offering a substantial advantage to our client on this project.
