A programme of monitoring was conducted during the course of marine geotechnical investigations associated with the development of the Greater Dublin Drainage Scheme in north County Dublin.
The development proposes the installation of a marine outfall of approximately 5km in length from the foreshore at Velvet Strand (Burrow townland) to an offshore point approximately 1km north-east of Ireland’s Eye.
Monitoring was required due to the high archaeological potential within Dublin Bay, including 12 recorded wrecks within 2km of the works corridor. Three investigative techniques were employed that had potential to impact on the archaeological resource: Cable Percussion Boring (Shell & Auger); Standard Penetration Testing and Vibracoring.
Works were carried out from a jack-up platform barge, towed into position by an assisting tug-boat. Monitoring was conducted from the barge between 30/07/15 and 22/08/15. Water depths ranged from approximately 3m to 29m and varied with tidal conditions. A total of ten site locations were monitored within the works corridor.
No finds, features or deposits of archaeological significance were encountered during the geotechnical site investigations phase of works. Future monitoring of dredging and associated construction activities will be required for this project.
