Who's in charge here?

In structuring the private side of an infrastructure PPP the most common teaming arrangement is developer/contractor-led with architect, engineer, and operators/service/equipment providers as secondary team members. This is by no means the only way to structure a public-private project but appears to be the most common. Certainly the flexibility of the model allows for finance-led, architect-led or engineer-led teams as the taste for PPPs grows and more projects are successfully delivered.
