Digital Twin Framework for Worker Safety using RFID Technology

Construction 4.0 and Digital Twin are the emerging concepts of the digital era in the Construction Sector. The crux of these digital technologies lies in capturing the rich "real physical" data to model the "virtual" structure to enable the experiments for specific decision-making. Although protocols for the hazardous operations had been chalked out meticulously across the globe through several organizations using stern safety regulations and codal provisions, still the goal of zero-accidents at the construction site has not been achieved. One of the several reasons for accidents occurrence can be that safety is not always in the minds of the workers and require a third-party intervention. Hence, the objective of this study is to safeguard the workers working in the construction sites using digital platforms (third-party) where the safety is monitored round the clock. The scope of this study is limited to falling of materials, equipments and workers. To achieve this objective, RFID (Radio Frequency Identification System) is used to capture the site data and is modelled in BIM (Building Information Modeling) using Dynamo. Job safety analysis is performed in the BIM software and this experiment is conducted on some hypothetical construction sites-in progress and the initial results have received positive feedback.
