Project summary:

Murphy Geospatial supported Virtus Project Management with survey solutions as part of the planning application and design for the redevelopment of the landmark former Player Wills and Bailey Gibson site on Dublin’s South Circular Road. 

The brief:

Murphy Geospatial was asked to conduct a site verification survey which consisted of a number of slit trenches verifying the routes of active and redundant gas mains from statutory records.

The challenges:

This renowned south inner-city site had been run down for a number of years, with heavy vegetation in particular creating a high-risk environment for the work required. A mechanical excavator removed excess vegetation providing a clear working zone for crews to scan and trace the ground using EML.

The cost of accidental strikes on buried services and cables is significant across the UK and Ireland and the lack of accurate data has been identified as a key concern. Murphy Geospatial recognises the importance of accurate subsurface mapping to help reduce risk and budget overrun on a project.

In this case, excavations using hand digging techniques alongside mechanical assistance verified the location of both active and redundant gain mains, concrete segments, and a masonry culvert.  


The findings allowed the team to compare historic records which shed light on the discrepancies in positioning. The position of the gas main had a vital role in the design and without knowing its true location, a worrying utility strike would have been inevitable.

Records and previous surveys also indicated the location of buried manholes across the site; we made it our objective to locate those manholes.

As we have shown with this successful project, Murphy Geospatial deliver services with the focus of reducing project risk while providing our clients with the data and information they need to make critical decisions at every stage of their project or asset life cycle.
