Our Role
Ayesa were appointed as specialist consultants to design the embedded secant pile wall on behalf of Murphy Ground Engineering. The pile wall consisted of 1200mm diameter piles in a traditional secant arrangement installed using bored piling techniques. The secant pile wall was designed to cantilever for an excavation depth of up to 8m to facilitate the construction of the underbridge. The approach walls were installed during normal working hours, with the lengths crossing the railway line installed during shorter night time possessions in the lead up to the main possession.
