Monitoring of engineer's test-pits was undertaken in 2004. The site is to be developed as a landmark tower, on the junction of the Grand Canal Locks with the Liffey at Britain Quay, Dublin 4. Eight test-trenches were excavated mechanically at sites chosen by the engineers. In addition, several geological bores were undertaken. The borehole results are summarised as follows: present ground level to 5m, fill with rubble, etc.; 5-11m, river silt; 11-20m, fine silty sand; 20-c. 29m, rock interface. This indicates a 5m depth of 18th-century dumped deposits. There is little chance of an archaeological horizon being present below 5m, which is river level.
