IR155-2 – PDRI: Project Definition Rating Index – Building Projects, Version 3.2


Welcome to this third edition of PDRI: Project Definition Rating Index – Building Projects. The first edition of this document was developed and written by the CII PDRI for Building Projects Research Team and published in 1999.

In 2006, the Support for Pre-Project Planning Project Team reviewed and updated all CII front end planning documentation, including that first edition. The team drew upon materials from the National Institute for Standards and Technology (NIST) Security Study performed by CII and the collective knowledge of the research team members. The resulting update (the second edition) significantly clarified the methods for using the PDRI–Building Projects tool, discussed tool usage by both owner and contractor organizations, and referenced security and sustainability issues.

The Front End Planning for Renovation/Revamp Research Team has now revisited the second edition to clarify its usage on renovation projects and to provide specific comments on needed front end planning efforts on renovation projects. In addition, a macro-enabled spreadsheet (an Excel™ file) has been developed that allows the project team to score projects automatically.

The research team believes that with these changes, this third edition significantly improves the usability of the PDRI–Building Projects tool.
