Projects Overview

Port Tunnel

Dublin Port Tunnel is the largest ever civil engineering project in Ireland.

It is the longest road tunnel in an urban area in Europe being a twin bore tunnel 4.5km in length with a height clearance of 4.65m and completes the northern part of the C-Ring around Dublin city.

Much of the Tunnel is between 21 and 23 metres deep with approximately 10 metres of rock and 12 metres of boulder clay above it.

The precision of the work involved on this project is illustrated by the fact that the allowed variation for the tunnel boring machines was + /-  6mm.

The overall budget for the Tunnel project was €752 million.

The 2003 Fleming Award for geotechnical excellence was won jointly by the World Trade Centre Recovery Effort and the Dublin Port Tunnel Team.

The project required over 3,500 thousand copings of varying styles and dimensions and these were manufactured and delivered by APC to the required specifications and schedules throughout the project.

Ardee Precast Concrete is delighted to have been associated with one of Ireland’s landmark projects.
