ABSTRACT
Loading several times already, and will continue to refer to this important period. One of the ways to determine if sufficient front end loading has been done is by completing a survey known as the Project Definition Rating Index (PDRI). The Project Definition Rating is a technique developed by the late John Hackney (Hackney, J.W. "Control and Management of Capital Projects," 2nd Edition, McGraw-Hill Inc., 1992) and propounded by the Construction Industry Institute (CII).3 It provides a rational 'system for a quantitative and objective evaluation of the status of the engineering. It is a very useful tool to determine the level of contingency required for the various types of cost estimates and also to determine the FEL.
