Adopting an integrated project delivery collaboration framework: a case study of a wastewater treatment plant project in Vietnam

Integrated project delivery (IPD) is introduced as a new delivery system that aims to transform and enhance the current delivery systems. For such an accomplishment, the IPD integrates people, systems, and business into an integrated platform delivering accurate information and new technologies in a collaborative team environment. In this sense, the current research reviews the IPD principles, benefits, and challenges, and creates a proposed framework that applies a percentage ratio with mathematical weight calculation to classify and identify the IPD collaboration level present in a construction project. For the data validation, a case study is performed, where the information of the WWWTP project is inserted into the proposed framework. The results illustrate that the case study scores a total sum of 30% of IPD collaboration present in the project, where it is classified as having a low IPD collaboration level. The significance of this study is that it helps project stakeholders in the construction industry to understand the important factors that lead to IPD adoption and develop the principles of IPD. The current study creates an updated and simple approach framework aiming to support the professional area as well as allowing a solid basis for future research.
