What About Us

Digital twin can be defined as a virtual representation of a physical asset enabled through data and simulators for real-time prediction, optimization, monitoring, controlling, and improved decision making. Recent advances in computational pipelines, multiphysics solvers, artificial intelligence, big data cybernetics, data processing and management tools bring the promise of digital twins and their impact on society closer to reality. Digital twinning is now an important and emerging trend in many applications. Also referred to as a computational megamodel, device shadow, mirrored system, avatar or a synchronized virtual prototype, there can be no doubt that a digital twin plays a transformative role not only in how we design and operate cyber-physical intelligent systems, but also in how we advance the modularity of multi-disciplinary systems to tackle fundamental barriers not addressed by the current, evolutionary modeling practices. In this work, we review the recent status of methodologies and techniques related to the construction of digital twins mostly from a modeling perspective. Our aim is to provide a detailed coverage of the current challenges and enabling technologies along with recommendations and reflections for various stakeholders.

Digital Twin: Values, Challenges and Enablers From a Modeling Perspective

Public and private blockchain in construction business process and information integration

This study proposes a technology- organization- environment (TOE) theoretical framework of critical factors that influence the successful adoption of blockchain technologies in the freight logistics industry and prioritize them using the analytic network process (ANP). The research findings indicate that ‘availability of specific blockchain tools’, ‘infrastructural facility’, and ‘government policy and support’ are the three topmost ranked significant factors that influence the adoption of blockchains in the freight logistics industry. These findings will aid government agencies, freight logistics firms and blockchain service providers in strategizing for the advancement and successful adoption of blockchain and improvement of overall organizational competitiveness.

Evaluating the factors that influence blockchain adoption in the freight logistics industry

The construction industry is faced with numerous challenges including low productivity, lack of research and development, and poor technology advancements . Advances in digital technologies such as digital twin (DT) has seen enormous utilisations in digitally advanced industries including the manufacturing and automotive industries. It presents an opportunity for the integration of the physical world to the digital world. DT technology has the potential to transform the construction industry and provide responses to some of its challenges. As a result, the concept of DT has attracted much attention and is developing at a rapid pace. The overarching aim of this study was to analyse the current state of DT applications in the construction industry. This study comprehensively reviews and analyses DT concept, technologies, and application in the construction industry using a systematic review methodology while incorporating the science mapping method. After a complete search of several databases and careful selection in line with the proposed criteria, 22 academic publications about DT application in the construction industry were identified and classified accordingly. The research analysed in detail the status, evolution of the concept, key technologies, and six areas of application in the lifecycle phases of a project: building information modeling , structural system integrity, facilities management, monitoring, logistics processes, and energy simulation. This research shows that there is a high potential for DT to enable solutions to the numerous challenges in the construction industry. Thus, this study raises the level of awareness and need for the application of DT in the construction industry.

Blockchain in the built environment and construction industry: A systematic review, conceptual models and practical use cases

Applications of distributed ledger technology (DLT) and Blockchain-enabled smart contracts in construction

Distributed ledger technology (DLT), commonly referred to as ‘blockchain’ and originally invented to create a peer-to-peer digital currency, is rapidly attracting interest in other sectors. The aim in this paper is (1) to investigate the applications of DLT within the built environment, and the challenges and opportunities facing its adoption; and (2) develop a multi-dimensional emergent framework for DLT adoption within the construction sector.

Key areas of DLT applications were found in: smart energy; smart cities and the sharing economy; smart government; smart homes; intelligent transport; Building Information Modelling (BIM) and construction management; and business models and organisational structures. The results showed a significant concentration of DLT research on the operation phase of assets. This is expected given the significant resources and lifespan associated with the operation phase of assets and their social, environmental and economic impact. However, more attention is required to address the current gap at the design and construction phases to ensure that these phases are not treated in isolation from the operational phase.

An emergent framework combining the political, social and technical dimensions was developed. The framework was overlaid with an extensive set of challenges and opportunities. The structured and inter-connected dimensions provided by the framework can be used by field researchers as a point of departure to investigate a range of research questions from political, social or technical perspectives.

Blockchain in the built environment: analysing current applications and developing an emergent framework

A Proposed Approach Integrating DLT, BIM, IoT and Smart Contracts: Demonstration Using a Simulated Installation Task

Distributed ledger technologies (DLTs) including blockchain are increasingly being investigated as a potential solution to address many of the challenges hindering the construction industry’s performance such as collaboration, information sharing and intellectual property rights. Existing studies addressing blockchain applications within construction and the built environment have ignored the interrelation of social and technological dimensions. To address this gap, this paper proposes a multi-dimensional emergent framework for DLT adoption within the construction sector. The framework was developed following a focus group discussion and took a socio-technical systems approach that encompasses three dimensions: political, social and technical. The framework was overlaid with an extensive set of construction-related challenges and opportunities and identified a number of associated agents across the dimensions. The structured and inter-connected dimensions provided by the framework can be used by field researchers as a point of departure to investigate a range of research questions from political, social or technical perspectives.
