ByrneLooby were tasked by our client Murphy Ground Engineering to carry out the design of the earth retention systems. We successfully developed efficient design solutions minimising temporary support requirements and realised significant cost and program savings for our client. The project was challenging as it required a deep excavation around the 110-year-old aqueduct. To ensure the existing structure remained largely unaffected by the excavation, strict movement limits were imposed. A further constraint was that the historic structure needed to remain live for the duration of the project. A combination of rotary bored piling and sheet piling were employed as the optimum solution for this project.
