Hegarty Demolition Engages LDG Datum on Dublin Demolition.

Hegarty Demolition commissioned LDG Datum to monitor demolition on their £10 million Abbey Street Lower Tourism Hostel project.

The project involved demolition of existing buildings on a 4,406sq metre site on Abbey Street and Abbey Cottages to make way for a nine storey building with 560 bedrooms, dining facilities, café, bar, reception area and meeting rooms.

Planning stipulated the monitoring of the existing surrounding buildings, and the LUAS tracks, which run parallel to the site of the demolition works.

LDG Datum’s monitoring, using Leica’s flagship robotic Multi-Station MS60 instrument, provided the vital control measures that ensure the stability of the surrounding super structures and LUAS tracks during the demolition phase of the construction works.

“Our on-site core activity included scanning of the LUAS tracks using Leica’s flagship robotic Multi Station MS60 instrument. The multi-station surveys the street every two hours and sends the data directly onto a secure webpage for the relevant parties to review.

“This data is then checked and compared to historical data allowing a safe protocol to be followed. Physical on-street precise levelling was undertaken weekly to provide the contractor with assurance and a back-up that the automated monitoring was working as planned. Vibration monitoring was also carried out on surrounding buildings during the demolition and construction phase.”
