“…Supply chain management is another application area that can benefit from the information traceability of blockchain technology. Information sharing in supply chain management can be fragmented due to involvement of stakeholders through multiple stages (Li et al, 2022). Thus, a framework that uses real-time digital ledgers for tracking the flow of materials from production to installation can improve the quality of the project (Brandín and Abrishami, 2021).…”

“…Thus, a framework that uses real-time digital ledgers for tracking the flow of materials from production to installation can improve the quality of the project (Brandín and Abrishami, 2021). The main contribution of these studies has been designing a system architecture that links the physical supply chain to the virtual layer to enable transparent and traceable management (Brandín and Abrishami, 2021;Hamledari and Fischer, 2021a;Li et al, , 2022Wu et al, 2022). A few studies have designed a blockchain prototype that is specifically for the supply chain management of off-site modular construction Wu et al, 2022).…”

Significant changes in the construction industry have been brought about by Building Information Modeling (BIM). While BIM has improved team collaboration and workflow efficiency, the model still faces multiple challenges. These are related primarily to the security, transparency, and reliability of the data shared in the model. A potential way to mitigate these problems, according to many studies, is blockchain technology. This paper reviews the recent literature on the integration of BIM and blockchain technology. Using a rigorous search-and-selection process, the authors conducted a systematic literature review by analyzing 70 studies relevant to BIM-blockchain integration. The state-of-the-art review explains how studies have implemented blockchain technology and provides an overview of different levels of adoption. Various application areas within the BIM process are explored to understand the ongoing research trend. The authors discuss limitations and offer recommendations on how best to implement future work in BIM-blockchain integration.

“…A few studies suggest the blockchain system with analyzing the current process of construction projects and concerning blockchain platforms [31], but there is a lack of a detailed method to overcome the hindrance of blockchain. Certain studies have recommended methods for reducing the size of the data stored in the blockchain [16], [32], and suggest the usage off-chain or sidechain methods for storing large-capacity data [27], [33], but also there is lack of detailed information for using the off-chain database. Those previous studies are comprehensive approaches and only applicable as alternatives in a limited number of cases and have not completely solved the limitations of the blockchain mechanism, which fundamentally distributes and stores the data.…”

As a temporary facility, scaffolding has an essential role in providing a work environment at height in the construction industry. According to the Occupational Safety and Health Administration (OSHA), approximately 65% of laborers work on scaffolding. Scaffolding work information needs to be effectively managed with reliability to provide a safe environment. However, managing information of the scaffolding work process remains challenging in forgery risk and manual verification. Blockchain has been widely introduced as an accountable and efficient information management solution. This study presents a blockchain-based system for scaffolding work to grant reliability and efficiency of information management. The system is developed to secure applicability by considering three aspects: (1) optimal blockchain platform regarding characteristics of scaffolding work; (2) storage method to address the hindrance of blockchain;(3) information needed to be compared for verifying adequacy. The detailed configuration and process model for the system is categorically presented, and validated via a case study. The case study confirmed that the system was able to store the information in the block smoothly, verify the information using the smart contract successfully, and remain the block size constant by using off-chain. The proposed system has the potential of practical applicability and could contribute to mitigate potential safety risks associated with inadequate scaffolding work management. Furthermore, the proposed system development flow can be leveraged as a guideline to extend blockchain applications to diverse areas in the construction domain.INDEX TERMS Blockchain application, construction safety, hybrid on-chain and off-chain system, scaffolding work, smart contract.

Effective security has become a vital part of our daily routine, for example securing cash, jewelry, documents, and other valuables. One way is to protect these items by keeping them in a safe box. However, current safe boxes are vulnerable to a number of security attacks such as physical, repudiation, anonymously modifying, etc. In this regard, this paper presents a robust smart safe box using the blockchain solution to ensure each transaction and secure it from unauthorized access. Also, it traces back the local safe items by reading back to blockchain data transactions and protecting them from thieves by tracking the burglar with a real-time tracking location Global Positioning System (GPS) tracker and capturing a picture and video recording through the external camera. Similarly, with more security enhancement using the TensorFlow framework to analyze optical detection and identify things inside the box using an internal camera. At the same time, each transaction is stored by using Write Once and Read Many (WORM) patterns saved in local private blockchain data block logs. Finally, it uses three-way authentication mechanisms to unlock the safe box that authenticates the users, (1) face recognition, (2) fingerprint and (3) the keypad password. The performance of the proposed smart safe box is tested by a number of hardware and blockchain tests. The results reveal that the proposed smart safe box ensures safe and authenticated access to the box and records each transaction using blockchain technology. Further, the performance evaluation of the private blockchain significantly improved the integrity and safeness of the proposed smart safe box.
