Integrated Project Delivery (IPD) is introduced as a new delivery system that fosters high efficiency by delivering accurate information and new technologies in a collaborative team environment. In this sense, the research aimed to review the IPD principles and their main categories, such as contract, process, information & modeling (I&M), team and communication as well as perform a qualitative analysis to illustrate the current research trends. The qualitative analysis performed was made through a series of collected articles from 2001 to 2018 in 08 different scientific database websites. In terms of the results, the contract category illustrated a strong trend, where the studies are focus on collaborations and frameworks to enhance high efficiency in construction. In the I&M category, demonstrated an increasing trend applying the Building Information & Modeling (BIM) subject as well as team category, where showed the importance of a wellstructured team and their impact on the project., The process and communication categories illustrated a weak trend, allowing opportunities in the field. Finally, the current study reviewed and analyzed the IPD and its main categories allowing a solid basis for future research.
The right selection of implementation system for projects in the construction industry is critical to achieve success. Integrated Project Delivery (IPD), is a comprehensive implementation system which has in recent years been seen to play an effective role in projects improved efficiency. Implementing an IPD system to resolve various problems of traditional systems is very important; however there are several barriers to its implementation. In addition, rooting and classifying the barriers is very significant in being able to resolve them. The aim of this study is the identification of barriers to IPD basically extracted from existing case studies. In this research, the meta-synthesis qualitative method is used for identifying and classifying the IPD barriers. The results are presented in a comprehensive table, and then are illustrated as a pattern by using macro concepts. This pattern is useful for presenting barriers to IPD. Identifying the barriers and resolving them are as important as identifying the benefits of IPD in creating motivation for construction industry owners. They also serve to provide the context for required predictions in implementing this approach in the construction industry.
