Designing and building large projects for the oil and gas industry requires extensive cooperation and coordination between the engineering, procurement, and implementation phases. In this research, to achieve a level of performance improvement in the project, we need a process called buildability, so to achieve this, we need to implement this process in large projects such as EPC in the oil and gas industry. In this study, we describe the principles of buildability as well as the conditions that limit the ability to build in the eyes of experts.
