Review of BIM-centered IoT deployment: State of the Art, Opportunities, and Challenges

Thanks to the digital representations provided through Building Information Modeling (BIM), successful adoption of emerging digital technologies have been increasingly reported within the constriction and facility management research community. On the other hand, the number of research studies exploiting the principles of the Internet of Things (IoT) to enhance automation and control for the existing construction and facility management systems has been increasing within the last decade. By realizing the ample opportunities that can be seized through a combination of IoT and BIM, researchers have started to explore the potential benefits of BIM-centered IoT deployments. In this light, this paper aims to report the sate-of-the-art research trends for creating integration between BIM and IoT. To this end, relevant studies have been carefully reviewed to highlight the previously used sensing technologies, IoT communication protocols, BIM-centered middleware components and their ultimate application scenarios. Moreover, some of the key opportunities available through technological advancements in both IoT and BIM disciplines, along with the major open challenges threatening successful implementation of IoT-enabled BIM systems are highlighted in order to provide suggestions for future research directions.
