Kent Station

The construction of a new entrance to Kent Railway Station in Cork, one of Ireland’s busiest railway stations aimed to create an enhanced link between the station and the city centre. The project included the addition of an underpass corridor link approximately 7 metres below ground level. One of the challenges for this project was the difficult ground condition and the need to undertake a deep excavation in an area with an extensive deposit of water bearing gravels.

Our Role

ByrneLooby prepared the detailed design of the specialist geotechnical elements to facilitate the construction of the underpass. A secant pile wall was installed along each side of the excavation. We devised a grouting strategy to control groundwater ingress into the excavation. The quality and validation proposals prepared by ByrneLooby were designed to allow the contractor to quickly gain confidence in the grouting solution as the works proceeded. The solution developed by ByrneLooby has provided a template for future deep excavations in the Cork city centre area.

“Typical solutions for achieving groundwater cut-off involve the installation of deep cut-off retaining walls. The particular ground conditions here precluded such a solution and I was tasked with coming up with an alternative solution for SIAC Construction. Through the sharing of in-house knowledge and experience I was able to develop an innovative grouting solution which satisfied the contractor and the overall client, Irish Rail.”
