O’Connor Sutton Cronin are involved in the management of infrastructure assets such as bridges and tunnels. We carry out inventory, general and principle inspections on non-national bridges as part of the Eirspan frameworks. In addition we carry our special inspections and assessments of bridges for clients such as NRA, RPA and Iarnrod Eireann. We have also carried out a special inspection of over 100 railway underbridges to determine their susceptibility to scour. We wrote a bespoke risk ranking metric for this exercise. We did something similar when we were appointed as the structural inspectors for the Dublin Port Tunnel. We have carried out the General and Principle Inspections of the tunnel since its opening to traffic in 2007. We have also carried out special inspections to facilitate speedy repairs with minimum downtime.
