PDRI: Project Definition Rating Index -- Infrastructure Projects, Version 4.0
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.
