Project Performance Impact

Application of the PDRI for Buildings template has been tested by the Construction Industry Institute (CII) on billions of dollars worth of building projects.  These projects included office, control buildings, recreation, institutional, and research facilities.

The table below compares project performance using their PDRI score at the time of project authorization (end of detailed scope). Projects with a PDRI score under 200 (a lower score indicates a better defined scope) consistently outperform projects with a PDRI score above 200 in terms of cost, schedule, and change orders.

PerformancePDRI Score < 200PDRI Score > 200Difference

Schedule 5% behind schedule 21% behind schedule 16%
Change Orders 8% of budget 11% of budget 3%
