Two common approaches have been used by governments for
the implementation of public-private partnerships (P3s):
a finance-based approach that aims to use private financing
to satisfy infrastructure needs, and a service-based approach
that aims to optimize the time and cost efficiencies in service
delivery. The implementation of P3s, however, may suffer
from legal, political, and cultural impediments. In the United
States, the federal government enabled a number of acts to
ease the impediments and promote P3s for infrastructure development.
Based on a detailed analysis of P3s in the United Kingdom
and British Columbia, Canada, this paper describes principles
that would characterize the implementation of P3s at the
program level (e.g., whether the implementation is successful).
The principles pertain to the: availability of a P3 legal
framework and implementation units; perception of the private
finance objectives, risk allocation consequences, and value-for-money
objectives; maintenance of P3s process transparency; standardization
of procedures; and use of performance specifications. Guidelines
for successful implementation are explained and discussed
in the context of the United States P3s experience and impediments.

In
traditional project delivery systems, payment mechanisms provide compensation
for the work performed using construction capital payments. In the alternative
public-private
partnership (P3) systems, payment mechanisms follow the selected
P3 system. For example, the build-operate-transfer
system provides compensation based on project demand using
real-tolls usage payments; the design-build-finance-operate
(DBFO) system provides shadow-tolls usage payments; and the
performance-based DBFO system provides compensation based
on contractor's performance using service availability
payments. Designing the payment structure is an important
task where several factors have to be considered. This paper
analyses the implementation of payment mechanisms in a number
of DBFO transportation projects in BC, Canada, in terms of
payment structure, payment types and characteristics, determination
and funding. The analysis provides insights for the design
of payment mechanisms. The analysis shows that more payment
types are being used and that the mechanisms are designed
to achieve specific government objectives. The analysis refers
to a new ‘hybrid' payment mechanism with elements
derived from the traditional and the P3 systems. The hybrid
system may have potential to minimize the overall project
cost; however, agencies have to be flexible in the delivery
concepts as combinations of payments for inputs, usage and
services might have to be used.

A
spectrum of requirements for the procurement of public
infrastructure under various public-private partnership
arrangements has been communicated by governments to the
private sector participants. This paper suggests a structure
for these requirements and demonstrates how they have been
realized in public-private partnership projects. Government
requirements are categorized and described under a structure
of three dimensions: rights, obligations, and liabilities.
Each dimension is further defined and explained through a
number of attributes. The structure provides insights as
to the basis for the different modes under public-private
partnerships such as build-operate-transfer,
build-own-operate-transfer, and build-transfer-operate.
The structure is used to examine government requirements
in a number of public-private partnership transportation
projects. The results show that, for each dimension and its
related attributes, comprehensive and clear articulation
of government requirements is generally needed. This will
reduce the amount of supplemental materials issued for the
request for proposals, help consortiums in responding with
proposals that can fit the requirements and reduce the amount
of time spent in negotiations and (or) the need for contract
amendments to reflect marketplace realities missed earlier.

This
investigation focuses on how forces - such as the will of
the government to extract resources to meet the public's needs and the
extent to which the national economy can produce them - have shaped the
use of P3s in developing transport infrastructure in Europe and the United
States. It begins by describing the different ways the public and private
sectors collaborate to develop transport infrastructure in the United
States and then compares recent experience and emerging trends
in P3 applications on both sides of the Atlantic.
