Public-Private Partnerships (PPP’s), in addition to elements of traditional design-build, may also contain financing, operations, and maintenance by the private sector. With public infrastructure needs at the state and local level often constrained by funding and resources, PPP’s have become an increasingly popular tool to get critical and complex projects built.

Shirley’s experience with PPP’s began in 2002 with the first PPP in Northern Virginia – the Route 28 Corridor Transportation Improvements Project for VDOT. Since then, Shirley has developed and delivered PPP projects for Prince William County and Spotsylvania County in Virginia.
