The Dunkettle Interchange Upgrade Scheme is a critical infrastructure
project, and one of the largest infrastructure projects in Ireland. Tailor
Engineering detailed several embankments, slopes and walls using
different reinforced soil techniques, using both steel and
geosynthetics as reinforcement, for a face area of +10,000 sqm.
John Sisk & Son Holdings Ltd (Sisk) have been awarded the contract
for the Dunkettle Interchange Upgrade Scheme by Transport
Infrastructure Ireland (TII). This design and build contract will
reconfigure the existing Dunkettle Interchange to remove a number of
traffic lights and create slip roads to increase the flow of traffic. The
project includes a series of direct road links between the N8, the N25
and the N40, a grade separated junction, new roundabouts, 50
structures of various forms and the provision of cyclist and pedestrian
facilities.
It was our pleasure to work with FTRC (Fehily Timoney and Company,
Ramboll and Clandillon Civil Consulting Ltd.) on such strategic
infrastruture project.
This project has won multiple prestigious awards, notably the 2024 Fleming Award from the British Geotechnical Association for solving complex ground challenges (awarded Dec 2024) and the ACEI Project of the Year 2025 (awarded 2025) for its scale and innovation, alongside other accolades from CECA and Ground Engineering Awards for its geotechnical excellence, sustainability, and overall delivery.
