Used by Royal Naval Vessels, the 28 metre wide by 600 metre long reinforced concrete jetty on steel tubular piles is located adjacent to the historic area of the Basin 1 complex at HMNB Portsmouth. The works impinged upon Ancient Monuments and a number of historically sensitive areas including HMS Victory and the Mary Rose. Consultation with English Heritage, Government, Local and County Authorities was necessary and option studies were presented at various stages. Precise monitoring of all historic sea walls and dock side structures, including below ground culverts and penstocks was undertaken with 3D geosensors at some 42 locations, with data storage for analysis. An alarm was linked to give early warning of possible damage during piling operations.
