A public-private partnership (P3) is a long-term contract in which a private party delivers and often operates a public asset, sharing risk and reward with the public sector. It is a delivery model, not a privatization.
The spectrum
From design-build contracts at one end to long-term concessions where the private partner finances, builds, operates and maintains the asset at the other.
Where P3s are used
Transportation, water, social infrastructure (schools, hospitals, courthouses, student housing), civic and mixed-use development on public land.
Why governments use them
Access to private capital and expertise, risk transfer, faster delivery, life-cycle cost discipline and budget certainty.
Common mistake
Assuming a P3 is free money. Private capital is repaid — through user fees, availability payments or ground rent — and costs more than public debt.
