I am trying to understand this. The public are trying to understand it. I accept there will be claims. If it was only a house that was being built, there would be variations. However, there is a substantial number of them in this case. A substantial amount of money is being sought. I am trying to get my head around how this came about. Is it the case that there were design changes and tweaks throughout the process in the past five years that caused many of these claims?
