Improving safety conditions at work is still a major challenge worldwide. Most fatal accidents occur in the AECO sector, regardless of the stringency of safety measures or the frequency of inspections. In addition, worksite safety is still assessed by traditional methods involving manual checklists and inspections that are mostly carried out visually. Support for inspection procedures at construction sites could be introduced through the implementation of innovative technologies, but the digitization that is sweeping the construction industry still struggles to address safety aspects. Official documents such as safety plans do not yet find a shared expression in the BIM approach, and innovative technological tools are not yet widely used. In this scenario, the proposed research work aims to support inspection processes through BIM modeling, the use of Augmented Reality and blockchain. These technologies are also integrated with a seamless indoor and outdoor localization system. Finally an information flow from site to office is pursued through image gathering and registering in a platform for real-time verification support configuring this way a true Digital Twin for safety management.
