Mr. David Moloney:

We have a number of ways, including through the spending review process, of testing this. We demand business cases for projects and we look at those. We have a major projects advisory group for very large projects. We have, therefore, means of assessing these projects. Again, however, we do not have engineering or other technical expertise and I do not think the Department needs to duplicate that type of expertise. Quite rightly, the Deputy mentioned the OPW. It delivers projects and therefore has architects, etc.
