Benchmark Performance Metrics for Integrated Project Delivery
• The processing time for change orders on an integrated design project was averaged at 1.9 weeks where a typical project processing time averaged at 4.8 weeks. The average RFIs per million was 3.9 on an integrated project compared to an average of 8 on a non-integrated project.
This study fills the gap in project delivery system research by evaluating the effects of IPD on building construction projects across a wide range of performance metrics from the perspective of general contractors and construction managers. This research demonstrates that IPD/near-IPD outperformed non-IPD projects with respect to performance in communication, change management, and business performance areas.
