Thank you very much, Chair.
Let me start by thanking the witnesses for being here today.
We can see that you are doing your best to answer questions that, frankly, are not in your purview. The committee is looking forward to receiving Mr. Tobi Nussbaum, the CEO of the National Capital Commission, when he gets back from vacation. He is the one who will be properly able to answer these questions. We can ask our questions at that time.
At the same time, it is educational for all members of the committee to get a better understanding of how the lines of accountability work. I appreciate some of the answers you gave earlier concerning the fact that the NCC submits a budget, but it's up to them to do the operational part of it.
There's just one question I have concerning abatement. We know that when we're renovating existing buildings, very often there are problems. An environmental assessment has to be done. There are other issues that can arise that wouldn't arise with brand new construction.
Mr. Ieraci, in your experience, what are some of those measures and why would they cost money?
