Mr. Chair, for projects procured as a P3, there are a lot of risks that are transferred to the private sector. What do I mean by those risks? That's where private finance comes in, because a risk is actually transferred if it happens and you don't pay for it. What value do you get out of that? I talked about whole life cycle optimization. By making a single person accountable, you get greater accountability to the taxpayer for the whole life cycle of the asset. It is one person. There is no pointing at who designed it, who built it, who is operating it. It is one person, and that person has backed up that accountability by putting his or her money on the line.
You get greater discipline by having capital market oversight. I have a tough organization, but I'm telling you the people who lend you hundreds of millions of dollars are tough on the contractors in a way governments just can't be. You get that discipline.
You get innovation. I didn't speak to that, but in a P3 procurement, you specify what you want rather than how to achieve it. You can say that you want it to do a certain outcome, but not that you want six inches of gravel and two inches of asphalt. You enable the private sector to think through the best way of drawing on global best practices to deliver that infrastructure. We're seeing that in terms of the prices we get back. In almost all cases, they're 10% to 20% less than what we even expected.
When you enable that innovation, you provide that discipline and you think of the whole life cycle. The whole life cycle is about the timing of it. Governments can sometimes say that they will do the maintenance next year, but the maintenance next year costs twice as much as the maintenance this year, because things that you push off cost more. On our $1.3 billion of investments to our $6.5 billion of projects, we have an estimated incremental savings of $860 million to taxpayers.
