Public-Private Partnerships and Concessions

Introduction
Public-Private Partnerships (PPPs) and Concessions are long-term contracting arrangements. Under them, a public authority (government, agency or municipality) works with a private entity to finance, design, build, operate and/or maintain infrastructure or public services. For the PMI Construction Professional (PMI-CP) credential, this topic sits in the domain of Contract Lifecycle and Delivery Methods. Candidates are expected to understand how these models differ from traditional delivery methods, how risk and revenue are allocated, and how the contract lifecycle runs over decades rather than years.

Why It Is Important
1. Closing the infrastructure gap: Governments worldwide face funding shortfalls for roads, hospitals, airports, water plants and energy systems. PPPs bring in private capital, expertise and innovation.
2. Whole-life value: PPPs bundle design, construction, operation and maintenance into one contract. This pushes the private partner to optimize lifecycle cost (total cost of ownership) rather than just initial capital cost.
3. Risk transfer: A core principle is that risk should sit with the party best able to manage it. Construction professionals must understand how risk allocation shapes pricing, insurance, bonding and claims.
4. Complex stakeholder environment: PPPs involve many parties: lenders, equity investors, special purpose vehicles (SPVs), EPC contractors, O&M operators, regulators and the public. Project managers must coordinate all of them.
5. Exam relevance: PMI-CP questions test whether you can pick the right delivery method for a scenario, find who bears a specific risk, and recognize lifecycle phases such as financial close, construction, operation and handback.

What It Is
Public-Private Partnership (PPP): A long-term contract (typically 15 to 40 years) between a public party and a private party.

• The private party provides a public asset or service.
• It bears significant risk and management responsibility.
• Its pay is linked to performance.

Concession: A specific form of PPP. The public authority grants the private party (the concessionaire) the right to build and/or operate an asset and to collect revenue directly from users (e.g., tolls, fares, tariffs) for a defined period. At the end, the asset usually transfers back to the government. In a concession, the private party typically carries demand (traffic/revenue) risk.

Key distinction: user-pay vs. availability-pay

• User-pay (concession) model: The private partner earns revenue from end users, such as toll roads, airports and ports. It bears demand risk.
• Availability-payment model: The public authority pays the private partner regular payments if the asset is available and meets performance standards, such as hospitals, schools and prisons. The public sector keeps demand risk. Deductions apply for unavailability or poor performance.

Common PPP structures (acronyms to know)

• BOT (Build-Operate-Transfer): The private party builds and operates, then transfers ownership at the end of the concession.
• BOOT (Build-Own-Operate-Transfer): The private party owns the asset during the term, then transfers it.
• BOO (Build-Own-Operate): The private party owns and operates indefinitely, with no transfer.
• DBFO / DBFOM (Design-Build-Finance-Operate-Maintain): Full lifecycle responsibility, including private financing.
• DBFM: As above, but the public sector operates the core service. The private party maintains the facility.
• BLT (Build-Lease-Transfer): The private party builds and leases the asset to government, then transfers it.
• ROT (Rehabilitate-Operate-Transfer): Applied to existing (brownfield) assets.
• Brownfield concession / asset recycling: Leasing an existing asset to a private operator for an upfront payment.

How It Works
1. Key parties

• Grantor / Contracting Authority: The public entity that defines needs, awards the contract and monitors performance.
• Special Purpose Vehicle (SPV) / Project Company: A legal entity created only for the project. It signs the project agreement and ring-fences risk from the sponsors' balance sheets.
• Sponsors / Equity Investors: Provide equity (often 10 to 30 percent) and take the highest risk for the highest return.
• Lenders: Provide senior debt on a limited-recourse or non-recourse project finance basis. Repayment relies on project cash flows.
• EPC / D&B Contractor: Delivers design and construction under a back-to-back subcontract with the SPV, often fixed price and date-certain.
• O&M Operator: Operates and maintains the asset during the concession term.
• Independent Engineer / Certifier: Verifies construction completion and performance, often for both lenders and grantor.

2. Lifecycle phases

• Phase 1, Identification and Feasibility: The public authority performs needs assessment and a Value for Money (VfM) analysis. It compares the PPP against a Public Sector Comparator (PSC), a hypothetical risk-adjusted cost of traditional public delivery. It also tests affordability and bankability.
• Phase 2, Structuring and Procurement: The authority defines the output specification (what must be achieved, not how), the risk matrix, the payment mechanism and the KPIs. Procurement usually involves an RFQ (prequalification), then an RFP, competitive dialogue or negotiation, then selection of a preferred bidder.
• Phase 3, Commercial and Financial Close: The project agreement is signed (commercial close). Financing agreements are executed and funds become available (financial close). Direct agreements give lenders step-in rights.
• Phase 4, Construction: The SPV passes construction risk to the EPC contractor. The independent engineer monitors progress. Revenue usually does not start until Commercial Operation Date (COD) or service commencement, so delays hurt the SPV heavily.
• Phase 5, Operation and Maintenance: Performance is monitored against KPIs. Availability payments may be reduced through deductions. Lifecycle renewals are funded through reserve accounts.
• Phase 6, Handback / Transfer: At the end of the term, the asset is returned in a specified condition. Handback surveys and retention or handback bonds protect the grantor.

3. Risk allocation (typical)

• Design and construction risk: Private (passed to the EPC contractor).
• Operation and maintenance risk: Private (passed to the O&M operator).
• Financing risk: Private.
• Demand/revenue risk: Private in user-pay concessions. Public in availability models.
• Political, regulatory and change-in-law risk: Usually public, or shared.
• Land acquisition and permits: Often public.
• Force majeure: Shared, with relief and sometimes termination provisions.
• Inflation and currency risk: Shared via indexation or hedging.

4. Key contractual mechanisms

• Output specifications: Define performance outcomes rather than prescriptive designs. This encourages innovation.
• Payment mechanism: Unitary charge, availability payments, shadow tolls or user tariffs.
• KPIs and deductions: Financial consequences for failing service standards.
• Step-in rights: Lenders or the grantor may take over a failing project.
• Termination and compensation: Provisions for grantor default, concessionaire default, voluntary termination and force majeure.
• Revenue sharing / refinancing gain sharing: Upside shared with the public.
• Minimum revenue guarantees: Government support to improve bankability in demand-risk deals.
• Relief events, compensation events and change mechanisms: Handle unforeseen events over the long term.

5. Advantages

• Access to private finance and off-balance-sheet treatment (in some jurisdictions).
• Lifecycle cost optimization and innovation.
• Clear accountability through a single point of responsibility.
• Greater cost and schedule certainty, since payment usually starts only when the asset is available.
• Risk transfer to parties best able to manage it.

6. Disadvantages

• Higher cost of private capital compared with government borrowing.
• Long, complex and costly procurement and transaction processes.
• Reduced flexibility for future changes over a 25 to 30 year term.
• Risk of renegotiation, disputes or concessionaire insolvency.
• Public and political scrutiny over tolls and tariffs.
• Needs strong public-sector capability to manage the contract.

Comparison with Other Delivery Methods

• Design-Bid-Build (DBB): Separate design and construction contracts. The owner finances, operates and holds most risk.
• Design-Build (DB): Single point of responsibility for design and construction, but the owner finances and operates.
• CM at Risk / IPD: Collaborative models with no private finance or long-term operation.
• PPP/Concession: Adds finance and long-term operation/maintenance. This creates whole-life accountability and the highest degree of risk transfer.

Exam Tips: Answering Questions on Public-Private Partnerships and Concessions
Tip 1: Identify the revenue source first. If users pay tolls or fees directly, think concession (user-pay) with private demand risk. If the government pays periodic fees tied to performance, think availability-payment PPP with public demand risk.

Tip 2: Apply the core risk principle. The right answer usually allocates each risk to the party best able to control or manage it at the lowest cost. Be wary of answers that transfer all risk to the private sector. Excessive risk transfer raises prices and reduces bankability, so it does not represent value for money.

Tip 3: Decode the acronyms. Read each letter: B=Build, O=Operate or Own (check context), T=Transfer, F=Finance, M=Maintain, D=Design, R=Rehabilitate, L=Lease. If the question says ownership stays private forever, the answer is BOO. If the asset returns to government, look for a T.

Tip 4: Know the SPV's role. The SPV is the contracting entity with the public authority. It ring-fences risk, and it passes construction and O&M obligations back-to-back to subcontractors. If a scenario asks who has the contractual relationship with the government, the answer is usually the SPV, not the construction contractor.

Tip 5: Watch for financing terms. Know these definitions:

• Non-recourse / limited-recourse finance: Lenders rely on project cash flows.
• Financial close: The point when funding becomes available.
• Step-in rights: Lenders can intervene to protect their investment.
• Debt service coverage ratio (DSCR): A measure of bankability.

Tip 6: Value for Money questions. If asked how a government decides whether to use a PPP, choose answers about Value for Money analysis, the Public Sector Comparator, affordability and risk-adjusted whole-life cost. Do not choose answers based only on the lowest initial construction price.

Tip 7: Output vs. input specifications. PPPs favor output- or performance-based specifications. If an option says the government prescribes detailed design methods in a PPP, it is likely wrong. Prescriptive designs undermine innovation and blur risk allocation.

Tip 8: Recognize the lifecycle stages. Expect scenario questions that ask what happens next. The sequence is: feasibility and VfM, then procurement, then commercial close, then financial close, then construction, then service commencement or COD, then operations with KPI monitoring, then handback.

Tip 9: Construction delay consequences. In PPPs, revenue typically starts only at service commencement. A construction delay therefore cuts SPV revenue and can trigger liquidated damages from the EPC contractor. Lenders become concerned, and the independent engineer may be involved. The government normally does not pay more for private-side delays.

Tip 10: Change in law and political risk. Questions often ask who bears the risk of a new government regulation that affects the project. General changes in law are often shared. Discriminatory or project-specific changes in law are typically borne by the public authority, through compensation events.

Tip 11: Handback requirements. Expect questions on asset condition at the end of the term. Correct answers involve:

• Defined handback criteria.
• Pre-handback inspections.
• Handback reserve accounts or bonds.
• Lifecycle maintenance plans.

Tip 12: Use elimination. Remove options that confuse PPP with simple outsourcing, traditional DBB or pure privatization. A PPP shares risk and responsibility over a long term under a contract, while the public sector keeps oversight and ultimate accountability for the public service.

Tip 13: Stakeholder and governance focus. PMI questions emphasize the project manager's perspective. Favor answers that show:

• Proactive stakeholder engagement (communities, regulators, lenders).
• Transparent governance.
• Clear contract administration.
• Structured change management and dispute resolution, such as dispute boards or expert determination.

Tip 14: Bankability keywords. A project that is not bankable will not reach financial close. If a scenario describes lenders refusing to finance a demand-risk project, look for answers such as government support, minimum revenue guarantees, viability gap funding or switching to an availability-payment model.

Sample Question Approach
Scenario: A transport authority wants a new highway but lacks upfront capital. Traffic forecasts are uncertain, and lenders are hesitant. What structure best balances risk?
Reasoning: Uncertain demand makes a pure user-pay concession hard to finance. The authority still needs private capital. An availability-payment DBFOM, or a concession with a minimum revenue guarantee, places demand risk with the public authority, or shares it. This improves bankability while still transferring construction and O&M risk to the private partner.

Key Takeaways

• PPPs are long-term, risk-sharing, performance-based arrangements that often include private finance.
• Concessions are user-pay PPPs where the private party collects revenue and usually carries demand risk.
• The SPV, project finance, output specifications, KPIs, step-in rights and handback are the defining features.
• Risk goes to the party best able to manage it, and VfM drives the decision to use a PPP.
• In the exam, identify the payment mechanism, decode the structure and trace the risk allocation. Then pick the answer that reflects balanced, whole-life value.
