A public-private partnership is a long-term arrangement in which public agencies and private parties share roles in delivering or operating infrastructure.
Definition
A public-private partnership, often called a P3, is an arrangement between a public agency and private parties to deliver or operate public infrastructure over an agreed period. Depending on the project, the private side may take on design, construction, financing, maintenance, operations, or a combination of these functions. Payment methods, procurement rules, performance requirements, and risk allocation vary by jurisdiction and contract. A civil engineering firm may join as a designer, technical adviser, or part of a broader delivery team, so its role and professional obligations need to be defined within that structure. A P3 is not one standard contract form, and the term does not mean the private party assumes every project risk. Owners should distinguish the overall partnership from the firm's specific services agreement and fee. The Federal Highway Administration describes federal transportation P3 resources, while project documents and applicable rules govern a particular procurement.
How owners use it
- Identify the firm's role in the broader team, such as designer, specialty consultant, or technical adviser.
- Include long pursuit periods and coordination demands when assessing staff capacity for a P3 opportunity.
- Example: A $75,000 design task plus a $15,000 authorized add-on equals $90,000 in authorized fees.
- Review payment terms, performance requirements, and liability provisions that flow down to the firm.
