Mr. Michael Nolan:

I do not have the exact detail on the variations on the Newlands Cross and N11 Arklow-Rathnew scheme, but one of the larger variations related to the reclassification of the dual carriageway on the N11 to motorway status. There was a big variation there with regard to signage delineation lighting and whatnot. Obviously it was a higher speed road open to 120 km/h as opposed to 100 km/h. There were other variations with regard to drainage upgrades. Part of the scheme was to revitalise a section of the road south of Arklow and Rathnew down as far as Gorey. It was 40 km of old dual carriageway which had to be refreshed. They were the main variations. I do not have the detail on the N17-N18 project but I think there were a lot of accommodation works variations. One junction was upgraded with a safer layout following a safety audit. There was one accommodation road coming down from a property where we saw an opportunity to lengthen the road and provide alternative access in the event of flooding which was a regular occurrence in the area. That provided some relief. It is that sort of thing.
