The American Institute of Architects, California Council, Releases Long-Awaited Update

SACRAMENTO, Calif.—Jul. 22, 2014 — What do you get when you combine a passionate group of architects, some clarification on the Integrated Project Delivery process, and an association who is motivated by both? “Integrated Project Delivery: An Updated Working Definition.”

This document, available for free on, is a long time coming. Initially developed in 2006, this handbook was still largely intact. But the Integrated Project Delivery Task Force recognized it could benefit by refreshing the definition and principles. The Task Force compiled a list of over 200 projects that use multi-party contracts to incentivize and reward their times in project execution, with likely hundreds or even thousands that use the principles of IPD to improve project outcomes. Thus, they began to draw some much needed lines in the sand. “We need a holistic approach to the entire delivery supply chain and stop throwing what we make over the proverbial fence,” said Zig Rubel, AIA, Definitions Committee chair. “IPD is the necessary bridge for our evolution in maturing the industry and this update defines the differentiation needed for clarity to get us there.”

It is largely this proliferation of projects using IPD principles that has prompted this Updated Working Definition. Projects using incomplete models of integration are often called “IPD-ish” have caused much confusion in the industry.

This document is now available on the AIACC website by clicking here. All one has to do is simply provide their email address and in what sector of the industry they are involved.

The Task Force will continue to use this document as the basis for developing recommendations for best practices. This is why the title is a “Working Definition,” as it is understood Integrated Project Delivery is still in its infancy.
