106. BIM Implementation in Mega Projects: Challenges and Enablers in the Istanbul Grand Airport (IGA) Project

The Architecture Engineering and Construction (AEC) sector has been facing considerable challenges recently due to the scale and complexity of the projects. Mega projects are more difficult to manage in terms of decreasing cost and increasing quality and productivity. Innovative approaches have been proposed to overcome the various challenges that the AEC sector tries to address. Achieving integration and thereby a more collaborative project environment is essential in this process. Today’s key trend in successful business strategy is put as “combine and conquer” which includes innovating business models together with transforming the core engineering systems around digital. Accordingly, it has been observed that there is rapid increase in implementing Building Information Modeling (BIM) in mega projects. BIM provides significant increase in efficiency of project execution through optimizing project constraints of scope, time, cost, quality, and resources. Therefore, incentivizing all project parties to work in a collaborative fashion can be considered as an important key success factor. This study investigates the challenges and enablers of BIM implementation through a case study on Istanbul Grand Airport (IGA) Project in Turkey to provide a solid understanding of BIM applications in mega infrastructure projects
