“…The use of virtual currency eliminates the need for bank notes or cash, reducing labor costs. It can also reduce late payment and default settlement [31]. In integrated project delivery (IPD), blockchain assists in the establishment of decentralized, automated, and secure financial platforms [32], where data providers are paid and users receive data [92].…”

“…Blockchain can store data securely and easily for query on the chain, providing support for the long construction cycle and reducing unnecessary work. Limited yet increasing studies explored the integration of blockchain and BIM in construction projects [31][32][33]. These studies, however, focus on applications in the financial aspects of construction (payment security, comprehensive project delivery) and security.…”

Blockchain and Building Information Management (BIM) for Sustainable Building Development within the Context of Smart Cities

‘Smart cities’ are a new type of city where stakeholders are jointly responsible for urban management. City Information Management (CIM) is an output tool for smart city planning and management, which assists in achieving the sustainable development of urban infrastructure, and promotes smart cities to achieve the goals of stable global economic development, sustainable environmental development, and improvement of people’s quality of life. Existing research has so far established that blockchain and BIM have great potential to enhance construction project performance. However, there is little research on how blockchain and BIM can support sustainable building design and construction. Therefore, the aim of this paper is to explore the potential impact of the integration of blockchain and BIM in a smart city environment on making buildings more sustainable within the context of CIM/Smart Cities. The paper explores the relationships between blockchain, BIM and sustainable building across the life cycle stage of a construction project. This paper queries the Web of Science (WoS) database with keywords to obtain relevant publication, and then uses the VOSviewer to visually analyze the relationships between blockchain, BIM, and sustainable building within the context of smart cities and CIM, which is conducted in bibliometric analysis followed by micro scheme analysis. The results demonstrate the value of this method in gauging the importance of these three topics, highlighting their interrelationships and identifying trends, giving researchers an objective research direction. Those aspects reported in the paper constitute an original contribution.

“…Wang et al [4] established a Hyperledger-based framework to address the challenges (e.g., poor traceability/timeliness of information) faced by the current precast supply chain and suggested that smart contracts are the sole channel for management personnel to interact with distributed ledgers. Furthermore, blockchain and smart contracts have been demonstrated to have advantages in integrated project delivery [5] and payment security [6].…”

The coding and deployment of smart contracts in the construction industry are challenging because of the gap between the generality of existing modeling approaches for such contracts and the pertinence of business logic to construction management. This research proposes a formal model for smart contracts in the context of quality acceptance in the construction industry to reduce the threshold for applying smart contract technology. First, a conceptual scenario of smart contract-based quality acceptance in construction is analyzed. Second, a finite state machine-based model is proposed to formalize smart contracts for quality acceptance. Lastly, a Hyperledger-based case study is performed to demonstrate the performance of the proposed formal model. This study contributes to the industrial application of formal modeling approaches for smart contracts in the field of construction.

Privacy, like security, is a non-functional property, yet most software design tools are focused on functional aspects, using for instance Data Flow Diagrams (DFDs). In previous work, a conceptual model was introduced where DFDs were extended into so-called Privacy-Aware Data Flow Diagrams (PA-DFDs) with the aim of adding specific privacy checks to existing DFDs. An implementation to add such automatic checks has also been developed. In this paper, we define the notion of refinement for both DFDs and PA-DFDs as a special type of structure-preserving map (or graph homomorphism). We also provide three algorithms to find, check and transform refinements, and we show that the standard diagram "transform→refine / refine→transform" commutes. We have implemented our algorithms in a proof-of-concept tool called DFD Refinery, and have applied it to realistic scenarios.
