The Office of Public Works (OPW) appointed GDG to provide geotechnical design advice for a collapsed river embankment on the River Feale in Listowel, Co. Kerry.
GDG has aided the OPW with the design, specification, procurement and management of an intrusive and geophysical site investigation campaign, composed of land-based cable percussion and rotary boreholes and river-based geophysical investigations, interpretation of results and production of a remediation design, involving placement of rock armour and slope face soil nail installation.
Immediately following the slope failure, GDG was requested to undertake a site inspection and advise the OPW on possible remediation measures to manage the risks posed by the failure.
GDG was engaged by the OPW to assess the collapse and design a repair solution. Our scope included:
GDG acting as PSDP for the duration of the project
GDG initially carried out a site walkover and background history desk study to highlight any immediate risks and investigate the potential remediation solutions.
Following the consideration of the proposed solutions, GDG was again approached to provide a design solution, developing a scope and specification for an intrusive and geophysical site investigation and providing management services throughout the works, assuming the role of PSDP for the project throughout the construction stage.
GDG completed all geotechnical and civil design components, including:
Produced the series 600, rock armor specifications, and drawings
