DOT Guides P3 Partnerships for Smarter Infrastructure Investments
Published Date: 3/3/2026
Notice
Summary
The Department of Transportation is sharing clear guidance on when and how to use public-private partnerships (P3s) for building big infrastructure projects. This helps project leaders figure out if teaming up with private companies saves money and works better than traditional methods. The guidance affects anyone applying for federal credit help and kicks in now, making sure projects get smart financial reviews without adding new rules.
Analyzed Economic Effects
7 provisions identified: 2 benefits, 0 costs, 5 mixed.
VfM Required for $750M+ P3 Projects
If a public project costs more than $750,000,000, is in a State with transportation P3 laws, and the sponsor seeks TIFIA or RRIF credit assistance and the project generates user fees or other revenues, the sponsor must conduct a value-for-money (VfM) or comparable analysis. The guidance says that the VfM must include the level of detail called for by the Infrastructure Investment and Jobs Act section 70701.
Detailed VfM for Title 23 $500M Major Projects
For projects funded under title 23 with an estimated cost of $500,000,000 or more that will be delivered as a P3, the Major Project financial plan must include a detailed VfM or similar comparative analysis. The guidance references IIJA section 11508 and 23 U.S.C. 106(h) as the basis for this detailed analysis requirement.
VfM Required Before Advancing Any P3 Seeking TIFIA/RRIF
Any project procured as a P3 and seeking TIFIA or RRIF credit assistance must complete a VfM or comparable analysis before deciding to advance the project as a P3, regardless of project size. The Bureau expects this initial VfM at Stage 1 (or Stage 1A for progressive procurements).
Stage 2 Detailed VfM: Required Elements
Before signing a concession agreement (Stage 2), the detailed VfM must include life-cycle cost and schedule, comparison of public funding versus private financing costs, any public contribution needed to cover shortfalls, assumptions about federal grants or loans, key P3 agreement terms (including expected private return), risk allocation and premiums, forecasts of user fees and revenues, and externality benefits. The Bureau lists these specific items as required components of the Stage 2 detailed analysis.
Transparency and Post-Implementation Reviews
Public sponsors must make VfM analyses and key concession agreement terms publicly available (subject to lawful limits) and post analysis results on the project's website as IIJA section 70701 requires. For title 23 P3 projects costing $100,000,000 or more that receive Federal financial assistance, sponsors must review the project and certify the private partner's compliance not later than three years after the project opens to traffic and make that certification or notice of non-compliance public.
Two Required Decision Points for VfM Analyses
The Bureau expects public sponsors to evaluate P3 appropriateness at two decision points: (1) after project identification and before project development (Stage 1), and (2) after procurement and before signing a concession agreement (Stage 2). For progressive procurements there is an additional Stage 1A initial VfM before a pre-development agreement and a detailed VfM before a concession agreement.
Independent Audit Recommended Before Contracts
The Bureau recommends conducting an independent audit, by an entity with no ties to the project, before signing contracts for projects subject to this guidance. The audit should confirm that processes were followed and major risks were identified and disclosed to decision makers.
