In all fairness, I think (& I'm speaking from rough memory here, not any detailed knowledge) that the safety record of Irish civil engineering contractors (i.e. major roads/bridges/tunnels) is pretty close to impeccable. The life-threatening safety issues we have seen in recent years related to house-building, apartment-building and/or office-building. We certainly didn't have anyone trapped in the Dublin Port Tunnel during contstruction (yet).
I don't want to bring up specific cases here for fear of the legal consequences of any innocent error but I can assure you there have been deaths on a number major civil engineering construction projects in recent years.
