Mr. Peter Finnegan:

It would be brickwork, chimneys, additional fireproofing, and addressing some of the voids that were discovered in the structure of the building that were not known when the surveying took place. There was an extensive amount of surveying done to the building beforehand, but it is impossible to catch everything as part of such a process. There will be a number of items that remain undiscovered right up to the point at which one moves on site.
