PPPs in the social infrastructure sector have historically suffered from rigid contract structures that fail to adapt to long-term service shifts. Hospitals, schools and civic facilities are not static assets; their operational needs evolve faster than the 25-year concession agreements that govern them. As public budgets across Europe tighten, authorities are revisiting the PPP model with a renewed focus on flexibility and performance-based risk allocation.

The traditional “Design-Build-Finance-Maintain” model is being refined. Recent guidance suggests a move toward hybrid structures where “hard” facility management risks remain with the private partner, while “soft” service delivery risks are shared or retained by the public authority. This nuance is critical. It prevents the private sector from pricing in unmanageable service volume risk, leading to more competitive bids and better value for money.

Sartori’s experience in recent social infrastructure mandates highlights a shift in payment mechanisms. We are moving away from simple availability-based payments toward “outcome-based” models. In a recent advisory mandate for a regional health authority, we structured a payment mechanism linked not just to facility availability, but to specific energy efficiency targets and patient flow metrics. This aligns the private operator’s incentives with the public authority’s actual service goals.
