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.

Performance PDRI Score < 200 PDRI Score > 200 Difference
Cost  3% above budget  9% above budget  6%
Schedule  5% behind schedule  21% behind schedule  16%
Change Orders  8% of budget  11% of budget  3%
