The redevelopment and remediation of the former Irish Steel East Tip on Haulbowline Island in Cork Harbour is one of Irelands largest contaminated land remediation projects. The challenge associated with this project was its interface with the sea for more than 1 km of its boundary. The need to project the marine environment during construction and as part of the final scheme was a key requirement of this project.
ByrneLooby were appointed by PJ Hegarty & Sons, working for Cork County Council, as designers of the coastal revetment element and temporary environmental containment works on this design & build contract. We designed a two-layer natural armour stone revetment to protect the site from wave activity. The revetment included a controlled permeability layer to manage leachate from the site. We also designed a temporary floating silt curtain, the longest employed in Ireland, to prevent runoff from the site during construction activities.
