Subsequently, the rapid digitization of construction work practices is providing opportunities to improve construction safety. Hence, construction researchers have been pursuing concepts, methods, and tools using advancing technologies to improve construction safety management.
The construction industry is prone to major safety hazards owing to the complex and onsite nature of construction projects.
The model proposal is designed exploiting the Veramo platform, hence the Ethereum Blockchain, and all the recommendations about Self Sovereign Identity systems given by the European Blockchain Partnership, and by the World Wide Web Consortium. It is proposed as an innovative system and companies that adopt the Open Innovation paradigm might want to pursue it.

In addition it allows the eligibility verification of the certificated information, providing also useful information for facility management. By exploiting the concepts of the Self Sovereign Identity, our proposal allows the identification of all involved stakeholders, the storage off-chain of all information, and that on-chain of the sole data necessary for the information notarization and certification, adopting multi-signature approval mechanisms where appropriate. The proposal ensures eligibility, transparency and traceability of all information produced by stakeholders, or generated by IoT devices appropriately placed, during the entire life cycle of a building artifact. This work presents a Self Sovereign Identity based system proposal to show how Blockchain, Building Information Modeling, Internet of Thing devices, and Self Sovereign Identity concepts can support the process of building digitalization, guaranteeing the compliance standards and technical regulations. However, Wi-Fi RFID tags may be expensive to implement where wireless internet is not readily available, such as new construction project. This technology may be suitable for construction sites where wireless networks are already available such as renovation projects. Checkpoint triggers or beacons, shown in figure 6, are essentially the devices that can read a tag within a much smaller range. One disadvantage however is that technology will require additional methods such as checkpoint triggers for locating the tag within a confined space since wireless access devices have a much wider range than RFID tags. This Wi-Fi tag shown in figure 5 has been used in the healthcare industry for tracking patient movement within a hospital. Another advantage is that expensive RFID tag readers are not required the equipment costs in tracking these tags may be lower. The first one is the range of distance a tag may be located to be picked-up by the reader is much higher with a wireless access point device. There exist two advantages of Wi-Fi RFID tags over other RFID tags. The Wi-Fi RFID tag connects to the wireless access point similar to a laptop computer. The Wi-Fi RFID tag can be read by any 802.1b or 802.1g wireless access point device instead of a RFID reader.
An active RFID tag requires the use of RFID specific infrastructure to read the signal transmitted called the RFID reader. new technology that will play an important role in the use of RFID tags in the future is the Wi-Fi RFID tag.
