Abstract

Previous CII research found that tools for measuring project scope definition and assisting alignment between project participants needed to be developed. CII formed the Project Definition Rating Index for Building Projects Research Team (RT 155) to produce an effective, simple, and easy-to-use scope definition tool for building projects. This research summary provides an overview of the research and development of PDRI–Buildings. It also discusses the usefulness of the PDRI on building projects.

RT 155 produced CII Implementation Resource 155-2, PDRI–Building Projects, which consists of 64 elements in a weighted checklist format and provides a method for measuring the completeness of project scope development. The PDRI–Buildings weighted index, based on industry best practices, allows its users to measure the level of scope definition and to compare scope definition to anticipated project success. This tool should help owners and contractors better achieve business, operational, and project objectives.

When using the PDRI–Buildings tool, the weighted score of a project can range up to 1000 points, with a lower score being better. Based on an analysis of 32 completed projects during the validation process, RT 155 found that projects scoring less than 200 (out of 1000 total points) were significantly more successful than those that scored greater than 200.

The PDRI–Buildings tool was used on several projects that were in-progress during the research. Lessons learned are presented to provide a better understanding of how to use the PDRI–Buildings tool in planning a project. Logic flow diagrams, developed to provide time-sequenced logic to project planning activities, are also included.
