0 Introduction
There is a growing interest in integrated project delivery (IPD) and the role building information modeling (BIM) can play in promoting integration among building professionals and improving design outcomes. This report reviews the Integrated Project Delivery (IPD) method of building design and construction and the main obstacles that are preventing it from being regularly adopted throughout the industry. Within the building industry, IPD is referred to by many names such as whole building design, integrated building design and so on. In this report IPD will be the nomenclature used throughout for consistency sake. This report covers briefly the background of BIM, IPD, how it is implemented, and reviews its advantages and disadvantages focusing more on the strengths and limitations of IPD in terms of Reducing Errors, Providing Greater Cost Certainty and Improving program duration. The last portion of the report identifies some of general solutions to obstacles to IPD implementation.
2.0 IPD and BIM
A major feature of IPD project is the mandated use of BIM under the IPD contracts that have been developed by the AIACC. In theory, this helps to further phase integration in the design and construction process. A project’s BIM platform compliments the project management tools set forth in the IPD documents by enabling collaborative meetings where the model is shared and virtual co-ordination. Detection of uncoordinated elements, trades and services can take place earlier to resolve issues before building components are assembled on site. In IPD BIM is the fundamental platform which enables 3D model integration and data sharing between team members. In the IPD model BIM technologies sit above an intranet which serves as ...

...s business interests of all parties. IPD encourages collaboration throughout the design and construction process, tying stakeholder success to project success, and embodies some certain contractual and behavioral principles. The Contractual Principles are; Key Participants Bound Together as Equals, Collaborative Decision Making, Liability Waivers between Key Participants, Jointly Developed Project Target Criteria, Shared Financial Risk and Reward Based on Project Outcome, Fiscal Transparency between Key Participants and Early Involvement of Key Participants. The Behavioral Principles are; Mutual Respect and Trust, Willingness to Collaborate and Open Communication. (AIA/AIACC, 2010).
In other words, IPD is a construction method in which the design team, owner, and contractor work together to develop a building from the initial concept through handover and operation.
