There is an independent engineer through the course of the process who has to certify that what they are doing is right. These engineers are not only hired by the public authority, but even more importantly they are hired by the investors. They report to the investors on whether or not these things.... If something goes wrong on performance—they do the wrong kinds of things—that will come back to the company and the investors. They won't get paid. So the investors also have a vested interest.
But it's absolutely through independent engineering advice. That leaves the government in the situation that when the independent engineer certifies, then, and only then, do we pay. We rely on independent engineering advice for payments.
