Procuring Infrastructure Public-Private Partnerships

Procuring Infrastructure PPPs Methodology


Since launching the report in 2015, the Procuring Infrastructure PPPs team has relied on cutting-edge research on the latest PPP practices around the world, as well as frequent consultations with PPP experts in various economies. As an initial step, the team conducted an extensive literature review to firmly document internationally accepted good practices, as well as understand challenges that governments and private companies face when entering into a PPP project. The team also consulted with the project’s Expert Consultative Group (ECG), which includes seasoned PPP specialists, academics, and individuals from the private sector. By supplementing the extensive literature with the consultations, the team was able to refine the 2018 survey, ultimately producing a set of questions that comprehensively measure global PPP good practices and enable robust cross-economy analysis. A detailed description of the technical aspects of the report may be found in the Methodology section of the report. Below is a summary of the research behind the report.

Thematic Coverage:

-    The questionnaire forming the basis of the report is divided into 55 major questions organized in four thematic areas: preparation, procurement, contract management, and a special module on unsolicited proposals (USP).

Survey Contributors:

-  The standardized questionnaire that generated the data for Procuring Infrastructure PPPs was distributed to approximately 13,000 contributors in the 135 economies included in the report.

-  Once the initial data collection was done, the team conducted a follow-up round of questions via conference calls and written correspondence to address and resolve any contradictions or discrepancies in the data provided by various contributors.

-  The preliminary data were finalized and then shared with the economy’s respective governments or the World Bank Group’s Country Management Unit (CMUs) for final validation.

-  The standardized questionnaire was distributed to practitioners who have a wealth of knowledge related to PPP systems. Respondents were selected on the basis of their experience and their availability to contribute meaningfully to the questionnaire.

 

Standardized Data and Comparability:

-  Standardized and comparable data are invaluable for valid cross-economy analysis, which is the central principle of Procuring Infrastructure PPPs 2018.

-  The use of a standard case study makes data collection easily replicable across economies and can make up for deep structural gaps between economies, which could jeopardize cross-economy contrasts.

-  In addition, the hypothetical case study can be easily applied to an extended set of economies in a seamless manner.

 

Case Study Assumptions:

-  The private partner (the project company) is a special purpose vehicle (SPV) established by a consortium of privately owned firms that operate in the surveyed economy.

-  The procuring authority is a national/federal authoritya in the surveyed economy that is planning to procure the design, build, finance, operation, and maintenance of, for example, a national/federal infrastructure project in the transportation sector (such as a highway) with an estimated investment value of US$150 million (or the equivalent in your local currency) funded with availability payments and/or user fees.

-  To this end, the procuring authority initiates a public call for tenders, following a competitive PPP procurement procedure.
