Rossaveel FHC Marine Site Investigation

Client: Department of Agriculture, Food and the Marine 

Engineer: Gavin & Doherty Geosolutions (GDG)

A detailed ground investigation was outlined to determine subsurface conditions in the footprint of the proposed slipway/boatyard (site 1) and the proposed Small Craft Harbour (site 2). Both sites were located within Rossaveel Fishery Harbour Centre Co. Galway. 

Ground Investigations Ireland were appointed to carry out the Marine Ground investigation to facilitate the safe and economic design of the works.

The Scope of the works included:

  • Provision of a Jack up barge with associated access and emergency vessels
  • 13 Cable Percussion Boreholes 
  • 13 Boreholes continued into rockhead by Geobore S 
  • Comprehensive sub sampling on site for laboratory testing 
  • Soil classification testing
  • Rock uniaxial Compression Testing 
  • Rock point load axial and diametral testing
  • Soil and rock shear box testing
  • Factual reporting

The works also required thorough communication with the Harbour Master due to the nature of mobilisation and demobilisation into the water, passenger vessels running during the ground investigation works and the unpredictable west of Ireland weather.   

As part of the Rossaveel dredging design and permitting project GII also provided support to the Geotechnical Design team in terms of the collection of high quality representative sediment samples. The data resulting from the analysis of the samples formed part of the consent process to allow the deposition of the dredge material at the proposed marine dump site. GII ensured that the samples were handled in the most appropriate way between the site and the in terms of samples storage and chain of custody requirements

Company Notice

He had an enormous lust for life and an unrivalled enthusiasm for all things geotechnical. James left an indelible mark on the careers and lives of so many people both in GII and in his personal life. He will be remembered by all for his spirit, his sense of fun and his generosity. His loss leaves an enormous void in the GII family that will be impossible to fill.
