Galway

Seamus Quirke Road

OVERCOMING DIFFICULT GROUND CONDITIONS WAS KEY FOR THIS PROJECT'S SUCCESS

The Bishop O’Donnell Road/Seamus Quirke Road Improvement Scheme involved the upgrading of approximately 2km of urban road including provision for bus lanes and dedicated cycle tracks along with the signalisation of key junctions. There was also an overall aim to increase traffic capacity between the suburban and coastal urban areas west of Galway and the city centre.

ByrneLooby designed temporary and permanent works for the scheme including the excavation and replacement of sensitive soft ground deposits beneath the road carriageway and the design of soil nailed slopes, which needed to aesthetically blended into the adjoining stone wall sections.

Difficult ground conditions were encountered, with the works further constrained by traffic management issues. The works involved the excavation and replacement of substantial depths of soft ground deposits in a phased solution, adjacent to a carriageway that needed to remain live during the works. The site was also located close to a number of facilities which would remain operational during the project. ByrneLooby designed an innovative phased excavation solution with the road supported by a sheet pile wall.

STAFF INSIGHT

“This was a complex project with very poor ground conditions on one of the major arterial routes through Galway.  A novel temporary works design, which required a first principles analysis, was developed in conjunction with the contractor in order to keep the traffic running whilst the works were undertaken.  This challenging job required us to provide a safe but innovative solution to satisfy all stakeholders.”
