Identifying the challenges of implementing the integrated project delivery method (IPD) in large residential projects in Iran

In this paper, integrated project delivery is used as an innovative project delivery system instead of the traditional method to address productivity issues in the construction industry, risk/reward sharing and delay in architecture, engineering and construction industry. The payment of interest to the parties is subject to the completion of all project activities. For this purpose, by using the qualitative technique, we have identified the challenges of implementing the above method in Iran. Data were collected by interviewing 18 people, all of whom were managers and experts in construction projects and contracts. The results of the analysis of the received information indicated 31 challenges for the implementation of IPD contracts. Based on the results of the research, the challenges were divided into four categories of legal contractual principles, structural principles, behavioral principles and technological principles in applying the integrated project delivery method in large residential projects in Iran. Likewise, the scale provides information that could be used by those managers wishing to improve productivity issues in their firms. In addition, the results show that the IPD has a positive impact on construction industry.
