Abstract The design and construction industry has long suffered low productivity and poor project outcomes. Collaborative approaches to project delivery offer an opportunity to transform outcomes by creating incentives in an environment that incentivizes high performance. This paper examines integrated project delivery (IPD), a collaborative contractual approach that alters a project’s fundamental commercial, organizational, and legal structures to minimize dysfunction and stimulate performance. IPD’s basic structures are introduced, followed by a critical examination of current and new research on IPD augmented by the author’s insights from structuring over 150 IPD projects. An online appendix provides additional information regarding the reasoning behind the IPD structures.
