PDRI: Project Definition Rating Index -- Infrastructure Projects, Version 4.0
Welcome to the fourth edition of the PDRI: Project Definition Rating Index – Infrastructure Projects, a document developed by the CII Research Team 268, PDRI for Infrastructure Projects. The significant software revisions of this edition were a part of a larger CII effort to revise and update all of the tools included in Implementation Resource 213-3, Version 4.0, The CII Front End Planning Toolkit.
Because it focuses on infrastructure projects, this PDRI tool filled a gap in CII’s front end planning body of knowledge. With the original release of this publication, CII completed the “trilogy” of planning tools focused on major capital projects, the other two of which are Implementation Resource 113-2, PDRI for Industrial Projects, and Implementation Resource 155-2, PDRI for Building Projects. Each of these three resources complements the others and will be applicable to most capital projects being constructed today, both new construction and renovation projects. Indeed, infrastructure planners will undoubtedly use a combination of these three tools, depending on the horizontal/vertical construction mix of their particular programs.
In addition to this publication, an updated macro-enabled spreadsheet helps project teams assess their projects. This Excel® file can be downloaded from the CII online store, along with this publication, or found in the enclosed CD.
IR268-2, PDRI: Project Definition Rating Index – Infrastructure Projects
The PDRI–Infrastructure tool consists of 68 elements, which are grouped into 13 categories that are further grouped into three main sections:
- Section I: Basis of Project Decision – 5 categories/23 elements
- Section II: Basis of Design – 4 categories/23 elements
- Section III: Execution Approach – 4 categories/22 elements
The tool provides a method for measuring the completeness of project scope development on infrastructure projects based on the collective professional judgment of the project team. Before detailed design and construction, project representatives make a comprehensive checklist of scope definition elements to be evaluated. These elements are then evaluated on the basis of their level of completeness. After all elements have been assessed, an index is calculated that gives the relative level of definition for the project.
