Diaphragm Wall
ByrneLooby was initially appointed by the specialist contractor Spie to design and detail the diaphragm wall. This wall facilitated the enormous 35m deep excavation, with the wall panels being 1.2m thick and 50m deep. A particular challenge was the detailing of the reinforcement for the wall panels, ensuring these large cages could be safely lifted from horizontal to vertical for placement into the excavation. Each cage weighed 25 tonnes necessitating a robust temporary works design.
