Those companies successfully appointed to the Qualification System will receive all future tender enquiries. Iarnród Éireann has over 450 bridges (structures greater than 2m) over water. All these bridges and riverbeds require periodic inspections. Some inspections are carried out yearly, other are every 3 years and more are on a 6 yearly cycle.
