MANTRA: Enhancing Worker Safety Through an Integrated BIM-IoT Mobile Application

In the evolving landscape of construction safety management, the integration of Internet of Things (IoT) and Building Information Modeling (BIM) technologies [1] presents a novel approach to addressing the dynamic challenges of workplace safety. The MANTRA project, developed under the ASSIST-IoT H2020 (Horizon 2020) project [2], introduces an innovative hybrid mobile application designed to enhance the safety of construction workers by providing real-time, interactive visualization and management of temporary danger zones on construction sites. This paper outlines the development and implementation of MANTRA, focusing on its integration of BIM for detailed site representation and ASSIST-IoT platform for real-time data exchange and alerts management. The application enables workers to identify and mark danger zones directly on digital site models, significantly improving the timeliness and accuracy of safety warnings. By leveraging cross-platform compatibility through Progressive Web App (PWA) Framework [3], MANTRA ensures widespread accessibility and usability. Preliminary results from field tests and lab evaluations demonstrate MANTRA’s effectiveness in improving situational awareness and reducing the risk of accidents. The application not only streamlines the process of marking and communicating hazards but also promotes a proactive safety culture. MANTRA’s contribution to construction safety represents a significant advancement in digital technology application, highlighting the potential for IoT and BIM integration in risk management and worker safety enhancement in dynamic work environments.
