Is P3 for Infrastructure, and Design-Build for Buildings?

Judging by Jim Parsons article in ENR, September 16/23, 2013, P3 projects are currently focused on road and transportation projects, and there is not much evidence that P3's are breaking into vertical construction:

• $1 billion, 29 mile I-95 Express Lanes in northern Virginia 
• $360 million second phase of the Presidio Parkway, San Francisco
• $840 million , 29.7 miile Nortwest Corridor covering Cobb and Cheorkee Counties, GA, 
• $1.5 billion replacement of Goethals Bridge, Elizabeth N.J. to Staten Island, N.Y. 
• $5.9 billion 21 mile I-4 Ultimate project in Orlando, Fl scheduled to begin next year

Meanwhile, the State of Nevada is undertaking its first P3 with Project NEON in Las Vegas, a  3.7 mile stretch to improve U.S 95/I-15 interchange.

Indiana DOT is looking for private investors to help build segments of I-69, a north-south shipping corridor in the southwest of the state.

As reported here, Maryland is pursuing P3 for its 16 mile Purple Line light rail link.

Jeff Levy, President & CEO of New York based Rail-Works predicts Baltimore's proposed Red Line and D.C.'s street car system will go P3.

Are we seeing infrastructure moving towards P3 and building construction moving towards design-build?
