Quantifying the performance of Integrated Project Delivery System in contrast with Design Build and Construction Management at Risk

Introduction and Background to the Problem
Integrated project delivery (IPD) includes extensive partnership needed for the present day dense construction. The American Institute of Architects (AIA) defines IPD as “a project delivery approach that integrates people, systems, business structures, and practices into a process that collaboratively harnesses the talents and insights of all project participants to optimize project results, increase value to the owner, reduce waste, and maximize efficiency through all phases of design, fabrication, and construction”. (AIA California Council, 2007) Becerik-Ghassemi and Gerber (2011) state that the parameters that differentiate IPD from traditional project delivery methods are:
a. It is a single contract signed by multiple parties
b. There is an early involvement of key participants
c. The awards and risks are shared between parties
d. There is liability waivers among key participants
e. The project goals are jointly developed
Asmar et al. (2013) found that IPD has been gaining recognition due to the various benefits it offers to the architecture/engineering/construction (AEC) industry and that much research has not been done to gauge the performance of IPD projects in contrast with other project delivery systems such as design-bid-build, design-build and construction management at risk systems. The metrics that are used to analyze the performance of IPD according to Mollaoglu-Korkmaz, Swarup and Riley (2011) are cost, quality, schedule performance, and owners perception of post-occupancy performance)
