Integrated project delivery (IPD) method with BIM to improve the project performance: a case study in the Republic of Iraq

Abstract

Design-build, design-bid-build and construction manager at risk are conventional approaches of project delivery and have many restrictions in the construction industry. To overcome these restrictions, in recent years, Integrated Project Delivery (IPD) has appeared as an approach to deliver the projects. IPD is a delivery approach in which the owner, designer, and constructor work together collaboratively to create a project from the initial stages to deliver and operating the building. Building information modeling is the best tool for creating a virtual model being used more often in conjunction with traditional delivery methods. The early involvement and collaboration characteristics of the IPD approach can enhance the coordination of BIM technology. In this paper, the researcher will identify the status of using IPD and other traditional methods in the Republic of Iraq. It also indicates the most important area when using the IPD method obtains the benefits of using this method and investigates how this system related to BIM technology. A questionnaire form was distributed, then collected and analyzed statistically. The results indicate that 83.33% of the respondents used the traditional methods, while 16.66% was used the IPD method.
