The Boat - Belfast

Employed by Quinn Piling to place piles in close proximity to a listed structure (the Lifeboat Bar), behind an installed CFA wall. Also to replace some CFA piles that were obstructed on dykes. The site had already been excavated to 1.5m below road level so access was difficult and piles exposed. Our compact, manoeuvrable rigs enabled us to complete this otherwise inaccessible site.
