Thank you very much for your question.
Those are very important questions to consider.
The taxpayer is ultimately important here.
I agree with you on that.
Let's think about the visitor welcome centre, just as an example. I know that Mr. Wright raised the different scenarios with you, but it's a great example.
There are different scenarios, and the costing would differ depending on them. For example, in the visitor welcome centre, phase two, we could have one point of entry or multiple points of entry. The decisions taken surrounding those items are going to cost different amounts.
