So, this example is a bit more of a 'traditional' public-private partnership - bringing together players from both sectors to build a revenue-generating infrastructure project. But this one is a VA facility - and VA projects are notorious for cost overruns, and the 'revenue' is actually more insurance and public budget to pay for services. 

Special laws had to be passed in Congress to make this P3 a reality, and it happened. The project is considered widely successful, in no small part because it was completed early and under-budget. This model of partnership can work on many more things than its traditional scope of infrastructure / real estate projects - we just have to be willing to explore, learn from others, and try it out.
