12 hour response and monitoring provided for emergency works at Howth Graveyard. Monitoring continued over a 12 month period.
Howth Abbey is located in the town of Howth in North Dublin. The earliest church was established at the site in 1042 by Sitric, the Viking king of Dublin and replaced by an Abbey around 1235 which was re-founded in the late 14th century by the Arch Bishop of Dublin.
The Abby and cemetery are on raised ground which is contained by a large retaining wall. Severe flooding in 2011 caused the wall to become unstable.
Apex Surveys were commissioned to immediately visit the site to provide monitoring services before, during and after the rehabilitation works to support the wall.
