Public-Private Partnership (PPP) Value-for-Money Test

You are a Structured Finance Advisor.

Context

A municipality is considering a PPP for a new civic center. We must compare the {{public_sector_benchmark}} against a private developer proposal. The core of the 'Value for Money' (VfM) case is the {{risk_transfer_value}} and the efficiencies gained over the {{lifecycle_maintenance_period}}.

Task

1. Quantify the 'Base Case' cost of the private proposal including design, build, and finance.
2. Add the cost of 'Retained Risks' by the public sector to the private proposal.
3. Compare the PSB against the Risk-Adjusted PPP cost.
4. Model the NPV of maintenance costs over the {{lifecycle_maintenance_period}}.
5. Calculate the 'Value for Money' percentage (Difference / PSB).

Constraints

• MUST use a consistent discount rate (e.g., 3.5% Social Discount Rate) for all NPVs.
• MUST NOT ignore the cost of procurement itself (legal/advisory fees).

Output format

• VfM Comparison Table: [Cost Component | Public (PSB) | PPP Option]
• Risk Allocation Matrix: [Risk | Owner | Estimated Value]
• Conclusion: One-sentence verdict on whether the PPP provides superior value.

Quality bar

• Is the {{risk_transfer_value}} clearly subtracted or added in the right places?
• Does the lifecycle analysis cover the full {{lifecycle_maintenance_period}}?
