Alexandra Quay, Ireland

Facilitating container ships at the terminal was key to this projects success

ByrneLooby provided a fully independent CAT III check of the design for a new €11M quay wall and crane rail beam at Alexandra Quay East in Dublin Port to facilitate container ships at the terminal. The challenge for this project was the incorporation of the existing quay structure within the new works.

Redevelopment works at the container terminal are currently ongoing and Phase 3 involves the refurbishment of the quay wall.  The old quay wall consists of a row of concrete caissons founded at differing depths which have on occasion been undermined. The new steel combi pile quay wall is designed to sit in front of the existing structure.

Our Independent Category III geotechnical and structural engineering check of the new 310m long, 18m deep combi wall ensured a cost effective, robust design for our Client and the Employer. The solution maximised the benefit of the existing structure in the design of the new quay wall retaining structure and its associated tie back system.

Scope of Project

  • Independent structural and geotechnical CAT III check of a new quay wall at Alexandra Quay East in Dublin Port.
  • The new quay wall is constructed in front of and incorporates the benefits of the old, existing quay wall structure.
  • The proposed solution for the new quay wall comprised a steel combi pile wall with an operational length of 310m and a depth of 18m.
  • The key challenge of our check was to ensure a robust solution for both our Client and the Employer, maximising any benefits of the existing structure within the new quay retaining wall system.
