Our Geotechnical Engineering team of experts in Dublin's involvement in Project Fitzwilliam initiated in assisting PJ Hegarty in their tender, by developing a practical construction sequence and risk mitigation measures associated with the demolition and subsequent basement works. On project commencement, ByrneLooby acted as specialist designers for P.J. Edwards for the detailed design of the perimeter secant pile wall. The secant wall comprised of approximately 400 linear metres, with over 650 No. piles to be installed. The wall was restrained with pre-stressed glass fibre reinforced polymer (GFRP) anchors under streetscapes. GFRP anchors were chosen and agreed with DCC to avoid obstructing potential future service installation beneath the adjacent streets. ByrneLooby also produced a detailed design of the 450 foundation bearing piles and 150 anti-flotation anchors for the substructure.
ByrneLooby acted as temporary works designer for PJ Hegarty throughout the project and assisted with a wide range of elements on site.
