Comparison of Key Project Performance Indicators of Different Construction Sectors in Terms of Collaboration and Integration

There is strong evidence to suggest that the use of collaboration and integration principles and methods improve overall project performance in the construction industry. Commercial Integrated Project Delivery (IPD) and Civil Infrastructure Alliance Contracting have specific collaboration and integration principles that define each as a unique delivery method. This paper investigates the similarities and differences between IPD and alliancing in terms of their key principles and explains the differences using the inherent differences between the construction sectors that have dominantly used each of the project delivery methods. The study uses 14 key performance indicators that are typically used to measure the performance of construction projects categorized into a) design optimization and b) construction risk management. The study concludes that IPD is more preferable for projects that require design optimization as the major KPI while alliancing might be more suitable for projects that deal with a significant amount of construction risks. The findings of this study can serve as a guide to properly identify collaboration and integration principles that will allow for better and enhanced project performance in a specific construction sector.
