Model Overview & DBFOM Structure

A public-private partnership (P3) is a long-term, performance-based contract in which a public health-system owner engages a single private consortium to design, build, finance, and typically operate and maintain a healthcare facility — repaid over decades through performance-linked payments rather than a lump-sum construction price. This article frames what P3 is, how the DBFOM family of structures is assembled, and the roles, money flows, and lifecycle logic that distinguish it from conventional delivery. The concession-agreement mechanics, risk transfer, availability-payment formulas, project-finance/SPV detail, value-for-money testing, healthcare scope splits, and the multi-stage procurement path are each developed in their own Articles and are only sketched here for context.

P3 is a procurement and financing model, not a construction method

P3 sits one layer above the familiar delivery methods (design-bid-build, CM-at-risk, design-build, IPD). Those methods answer "how is the building designed and built and under what contract form." P3 answers a larger question: "who owns the lifecycle risk, who provides the capital, and over what horizon is the facility paid for." A P3 is best understood as a commercial and financial wrapper around delivery — the actual design and construction inside the wrapper are almost always executed as a design-build (or progressive design-build) subcontract.

The defining features of a P3, as practiced for public healthcare in the US, Canada, the UK, and Australia, are:

Bundling. Design, construction, financing, and (usually) long-term facility management are procured as one integrated package from one accountable counterparty, rather than as separate contracts let sequentially.
Private finance. The private partner raises the capital — debt and equity — to fund construction, so the public owner avoids a large up-front capital outlay and instead pays over time.
Long term. The concession runs for a long horizon, commonly on the order of 25 to 35 years, spanning construction plus decades of operation.
Performance-based payment. The owner pays only when the asset is available and performing to contractual standards; deductions apply for unavailability or service failures. Payment is for an outcome (a functioning, standards-compliant facility), not for inputs.
Whole-life accountability. Because the same partner that builds the facility also maintains it for decades, the model is intended to align design and construction decisions with long-run operating cost and reliability.

Critically, in the healthcare P3 models common in North America, the public owner almost always retains all clinical service delivery — physicians, nurses, and care operations stay public. The private partner's scope is the building and its "hard" and "soft" facility-management services, not patient care. This clinical/non-clinical boundary is a defining healthcare-specific trait and is developed in its own Article.

DBFOM is the canonical structure; DBFM is the common healthcare variant

P3 structures are named by the bundle of responsibilities transferred to the private partner. The acronyms stack the delivery verbs:

Acronym	Stands for	What the private partner does	Typical use
DBF	Design-Build-Finance	Designs, builds, and finances construction; hands the asset back at substantial completion. No long-term O&M.	Short-term financing bridge; owner keeps operations.
DBFM	Design-Build-Finance-Maintain	Above, plus long-term maintenance of the building/hard FM over the concession.	Most common North American hospital P3 structure.
DBFOM	Design-Build-Finance-Operate-Maintain	Above, plus operation of building services (and sometimes soft FM such as housekeeping, catering, security, helpdesk).	Used where the owner wants to transfer broader non-clinical operations.
DBFOM with WLC	DBFOM with whole-life-cost / lifecycle obligation	DBFOM with an explicit handback condition obliging the asset to be returned in a defined state.	Standard refinement of DBFOM/DBFM concessions.

For acute-care hospitals, DBFM is the workhorse: the consortium designs, builds, finances, and maintains the physical plant (the "Maintain" covering hard FM — building fabric, mechanical/electrical, lifecycle renewal of components), while the public health system operates the clinical enterprise and frequently retains soft FM. DBFOM extends the transfer to "Operate," pulling in non-clinical operations (e.g., facilities operation, portering, sterilization-area servicing, parking, retail). Where exactly the line falls between Maintain and Operate, and which soft services transfer, is negotiated project by project.

The thread common to all of them is the F — Finance. Removing the "F" yields a design-build or design-build-operate-maintain delivered with public money up front; it is the private financing, repaid through availability payments over the concession, that makes a contract a P3 in the sense used here.

The structure is organized around a special-purpose project company

A P3 is delivered through a project company — a special-purpose vehicle (SPV), also called Project Co — created solely to execute that one concession. The SPV is the public owner's single counterparty and the legal hub through which every obligation and payment flows. The full project-finance and SPV mechanics (equity/debt structure, lenders, security, refinancing) are covered in the financing Article; the overview here is the org chart.

A typical healthcare P3 structure links the following parties:

Public-sector owner / procuring authority — the health system, hospital authority, or government department that needs the facility, defines the output specification, runs the procurement, signs the concession agreement, and makes the availability payments. It retains clinical operations.
Project Co (SPV) — the special-purpose company that signs the concession agreement and is contractually responsible for delivering everything. It holds the equity and debt, and passes obligations down to its subcontractors.
