Project Outline The Dublin Port Berth 29 Project was a key element of the Alexandra Basin Redevelopment, which is the first major infrastructure project from Ireland’s Dublin Port Company Masterplan 2040. This new infrastructure is required for the deepening of the berth from -9 to -13 CD to ensure that the port has the capacity for the anticipated future trends/growth. The project is also required to meet the immediate needs of DPC and its stakeholders to cater for the needs of a range of ship and cargo types providing a multipurpose berthing facility whilst minimising the interface issues with key stakeholders. The piling works involved the installation of a 120m long combi pile wall which included steel tubes 33m, 1420mm diameter, 25mm wall and sheets piles Az28-700. Continuous Flight Auger Reinforced Concrete piles 900mm diameter were installed for the anchor wall and bored piles supported a ship to shore crane rail and storm bollard bases. All piling works were completed using Murphy own inhouse piling equipment and expertise. 115mm steel tie rods were installed to link the combi pile quay wall to a piled anchor wall offset 30m from the quay wall. Tie rods were installed in the tidal zone which required detailed coordination around tide times. Following our recent completion and handover of Berth 29, Murphy was awarded the contract for Berth 30/31 & McCairns Yard Bulk Handling Facility, under the Dublin Port Single Party Framework. This project is now underway with an expected completion date of July 2026. KEY FACTS Demolition works included the removal of the existing quay wall and apron slab to below tie rod level within the tidal zone. Mass concrete including the existing caisson structures were removed by hydraulic excavator mounted breakers, concrete was crushed to a 6F2 grading using hydraulic excavator mounted crushing buckets for re-use. The earthworks on the project included the excavation of over 12,000m³
