Management and Implementation of projects highly depend on the contract type chosen at the beginning of the project. This will affect all the project performance measures such as cost, schedule, and quality. Thus, choosing a proper contract type as the first step in implementation of any project is so important. The fragmented nature of conventional contracts hinders collaboration among project key parties. Integrated Project Delivery (IPD), a new method in implementation of construction projects, seeks to improve project outcomes through a collaborative approach of aligning the incentives and goals of the project team through shared risk and reward, collaborative decision making, early involvement of all parties, and a multi-party agreement. Although Integrated Project Delivery (IPD) is a relatively new method, at least, six different standard contracts have been published to date addressing this method. This paper introduces Integrated Project Delivery (IPD) by its important elements according to the AIA Document C191 - 2009 (a standard form of multi-party agreement). In this paper, Integrated Project Delivery (IPD) will be introduced firstly, and then barriers to utilizing it in Iran will be discussed. For the purposes of this paper, 19 Iranian construction industry experts were interviewed once to rank importance of IPD implementation barriers, and after that, to suggest and find practical solutions to resolve the identified problems. Lack of a domestic IPD standard contract \& lack of Building Information Technology (BIM) and experts in this field in Iran ranked as the most important precludes. The problems are categorized in four main groups: legal issues, financial issues, cultural issues, and technology related issues. Researchers believe that the results of this research will help to recognize the prerequisite of IPD implementation in Iran.
