“…Their study also helps to raise awareness about the cybersecurity implications of implementing such technologies and operational technology attacks in the AEC industry. Shemov et al (2020) discussed the main challenges faced in the construction supply chain (CSC) and proposed a blockchain platform to enhance security. Using a hypothetical CSC scenario, they performed a partial threat analysis on a blockchain model to identify potential attacks and countermeasures required to prevent them.…”

The architecture, engineering, and construction (AEC) industry is increasingly becoming digital and more prone to cyber-attacks. Although there are several studies and standards in the cybersecurity domain, experts suggest that domain-specific studies need to be conducted to address the unique challenges faced within each of the different industries. Therefore, several cybersecurity studies have been undertaken for various industries, such as healthcare, manufacturing, telecommunication, and energy. However, this type of study is largely missing in the AEC industry due to different reasons, including lack of awareness. To address that, this study aims to (a) compare and analyze the number of cybersecurity-related documents in the AEC industry with several other industries, and (b) extract and analyze the cybersecurity-related documents data to identify potential future research trends and topics for the AEC community. The Web of Science (WOS) database, consisting of significant and influential journal publications, was used for document retrieval. VOSviewer was used to identify key research topics and trends in the cybersecurity domain and define future cybersecurity research in the AEC industry. WOS document retrieval results that compared the total number of publications corroborated the little to no attention received to cybersecurity investigation in the AEC industry. In addition, the VOSviewer analysis revealed three significant areas of research in the cybersecurity community that provide a reasonably justified roadmap for conducting cybersecurity research in the AEC industry. This study could greatly benefit the AEC research community and potential reaping benefits to the industry by creating more awareness among different stakeholders.

“…Penzes (2018) noted that transactions through blockchain can lead to dynamic payments for logistics actors, and improved communication with the contractor. Moreover, the tampering with past logistics data can be avoided through the consensus required for the block updates and the storing of the complete transactional history (Penzes, 2018) something that can also reflect positively on issues of productivity and efficiency (Shemov et al, 2020). Accounting rework and data errors across multiple ledgers can be reduced, which in turn can bring time and cost savings (e.g.…”

Blockchain technology has a potential for construction logistics, also within Sweden. In this paper, a proposal of a blockchain system and its practical implementation is presented (the BLogCHAIN prototype). BLogCHAIN was preliminarily tested during the early construction of a school in Sweden, in November-December 2020. Methodologically, we reviewed studies on blockchain for construction logistics, interviewed the BLogCHAIN testers (suppliers and contractor's operatives), and understood the test's practical outcomes through sociomateriality. Our results include the confirmation of envisioned benefits when implementing BLogCHAIN (e.g. reducing accounting rework), but also a simplification from its initial conceptualization, mainly due to rigidly established work practices. THEORY SociomaterialityThe theory of sociomateriality emphasizes that the material and social aspects of (digital) technologies are inseparable and fused in practice (Orlikowski & Scott, 2008,2016. Actions of utilizing the digital technology are no longer considered to be exclusively human properties, but are performed through interactions between humans and non-humans (Moura & Bispo, 2020).

“…Penzes (2018) claimed that blockchain-induced transactions can result in dynamic and instant payments for suppliers, transporters, and subcontractors, as well as better communication with the main contractor. Moreover, the visibility of the complete transactional history across the construction supply chain and the consensus requirement for the block updates, are exemplified for tackling the tampering with past logistics data (Penzes, 2018) and issues of productivity and efficiency (Shemov et al, 2020). Furthermore, blockchain is envisioned to reduce administrative rework (e.g.…”

“…Finally, the potential constraints and security issues regarding the implementation of blockchain, two topics that are quite widely researched outside the field of construction, are only limitedly considered in a few constructionrelated studies (e.g. in Barima, 2017;Perera et al, 2020;Sharma and Kumar, 2020;Shemov et al, 2020;and Yang et al, 2020). To expand this limited consideration, we investigated blockchain-related studies outside the field of construction.…”

A conceptual digital business model for construction logistics consultants, featuring a sociomaterial blockchain solution for integrated economic, material and information flows

In this paper, a new digital business model for independent construction logistics consultants, which features the conceptualization of a sociomaterial blockchain solution for integrated information, material and economic flows, is proposed. Theoretically, we offer an understanding of the economic flow, stress the optimization of construction logistics through flow integration, analyse current approaches to understanding blockchain, adopt sociomateriality to envision a suitable blockchain solution, and consider the way blockchain can constitute part of the value proposition of a related digital business model. Methodologically, we systematically reviewed the literature on blockchain-related construction research, and conducted empirical studies on independent logistics consultants in the Swedish context for more than a year. On the one hand, the literature review reveals that core blockchain properties can generate value for construction logistics (e.g. shared ledger structure and reduction of accounting rework) – however, apart from visions and prototypes, there currently exist no use cases, and potential implementational constraints and security issues are limitedly considered. One the other hand, the empirical findings show that independent construction logistics consultants in the sociomaterial Swedish context are suitable candidates for the proposed digital business model. By combining the literature and empirical insights, a permissioned private proof-of-authority blockchain solution integrating the supply chain flows in a generic sociomaterial setting is conceptualized. This solution is then embedded in the value proposition of a digital business model for an independent construction logistics consultant. The proposition includes, among others, improved process management and increased productivity, while the consultants’ competitive advantage through innovation is facilitated. Other business model segments, like key resources, are also updated via the blockchain solution, while some, like channels, are not significantly affected. To not hinder the realization of this digital business model, issues like the lack of blockchain awareness, and the existing power balances within sociomaterial constellations, have to be addressed.
