Full-text available
Onsite assembly is a critical stage for modular construction. Its success or failure depends on accurate information sharing among numerous stakeholders who, unfortunately, often possess unsynchronized information. Owing to its decentralized consensus mechanism, blockchain has the potential to improve information-sharing accuracy on construction si...

Configuring a trustworthy Internet of Things (IoT)-enabled building information modeling (BIM) platform (IBP) is significant for modular construction to ensure transparency, traceability, and immutability throughout its fragmented supply chain management. However, most current IBPs are designed adopting a centralized system architecture, which fail...
Article
Traditionally, construction managers were considered more experienced in project management than off-site production management, although the latter is gaining importance with the renaissance of modular construction worldwide. Various Internet of Things (IoT)-enabled Building Information Modelling (BIM) platforms have been developed to facilitate p...

Unstructured texts dominate data in construction projects. With the achievements of natural language processing (NLP) techniques, mining unstructured text data for smart construction has become increasingly significant. To understand state-of-the-art NLP for smart construction, uncover related issues, and propose potential improvements , this paper...
Article
Many cross-knowledge domain tasks involving various professional backgrounds have been transferred from construction sites to factories in modular construction (MC). In MC, forming optimal work packages which can handle the complexity of product breakdown structures and dynamic project progress is critical for task planning and execution. However,...
Article
Fatigue of operators due to intensive workloads and long working time is a significant constraint that leads to inefficient crane operations and increased risk of safety issues. It can be potentially prevented through early warnings of fatigue for further appropriate work shift arrangements. Many deep neural networks have recently been developed fo...
Article
Blockchain technology has attracted the interest of the global construction industry for its potential to enhance the transparency, traceability, and immutability of construction data and enables collaboration and trust throughout the supply chain. However, such potential cannot be achieved without blockchain "oracles" needed to bridge the on-chain...
Article
Full-text available
Recent technological advancements in geomatics and mobile sensing have led to various urban big data, such as Tencent Street View (TSV)photographs; yet, the urban objects in the big data have hitherto been inadequately exploited. This paper aims to propose a pedestrian analytics approach named Vectors of Uncountable and Countable objects for Cluste...
Article
Full-text available
Blockchain technology has been explored for governmental supervision of construction work (GSCW) due to its merits of traceability, immutability, and transparency. However, its decentralized nature is seemingly incompatible with GSCW, which is a type of centralized governance per se. This research aims to find a network topology with a proper level...
Article
[Free PDF: 🌐 https://authors.elsevier.com/c/1c~tz3IhXMpsEg 🌐] The rapidly expanding number of IoT-based camera devices makes smart work packaging (SWP) easier to access massive construction workers’ personal image information for occupational health and safety (OHS) status monitoring. SWP can then transmit these personal data to the cloud for train...
Article
By manufacturing housing products off-site and assembling on-site, modular construction can significantly improve the housing supply efficiency, particularly for high-density cities. However, off-site modular housing production (OMHP) supervision is currently problematic. The production parties are reluctant to provide detailed private data; Even w...
Conference Paper
Fatigue of operators due to intensive workloads and long working time is one of the significant constraints lead to inefficient crane operations and safety issues. It can be potentially prevented through early warnings of fatigue for further appropriate work shift arrangements. Recently, many deep neural networks have been developed for the fatigue...
Article
Lean thinking has been proven effective in helping practitioners identify and eliminate wastes during engineering operations. However, systematic instructional mechanisms and training protocols based on individual trainee's performance are insufficient in existing training to define value-added activities for further productivity improvement in a t...
Article
Full-text available
Construction projects require the effective collaboration among the various types of stakeholders involved to succeed, thus leading to stakeholder perspective studies in construction projects. The study proposes an integrated bibliometric approach to detect the knowledge evolution, domain and frontier with a broader searching scope compared with ma...
Article
Prefabricated building projects (PBPs) have gained worldwide popularity over the past few decades because of their various benefits. Supply chain management (SCM) is critical to the successful delivery of PBPs because supply chains are complex, involving multiple processes and stakeholders. Poor SCM in PBPs causes cost overruns and schedule delays....
Article
Prefabrication housing production (PHP) processes are fragmented and full of variability. Their schedule reliability is particularly disturbed by the constraints deriving from task executions in the on-site assembly process. Proactive constraints modeling, including identifying constraints and understanding their interrelationships, is crucial to e...
Article
Full-text available
Although prefabrication housing production (PHP) has been widely advocated with advantages like ensured good quality and secured workplaces, its poor interoperability and fragmentation still causes various constraints, limiting the progress of projects. This paper aims to model the constraints and their relationships in task executions of different...
Article
The decision-making system in Prefabrication Housing Production (PHP) lacks efficiency and collaboration because relevant information is stored and managed in heterogeneous systems of various stakeholders, who are commonly geographically isolated. Building Information Modeling (BIM) has advantages of combining its object-oriented attributes and the...
Article
Building Information Modelling (BIM) serves as a useful tool in facilitating the on-site assembly services (OAS) of prefabricated construction for its benefits of powerful management of physical and functional digital presentations. However, the benefits of using BIM in the OAS of prefabricated construction cannot be cultivated with an incomplete,...
Article
Foundation pit displacement is a critical safety risk for both building structure and people lives. The accurate displacement monitoring and prediction of a deep foundation pit are essential to prevent potential risks at early construction stage. To achieve accurate prediction, machine learning methods are extensively applied to fulfill this purpos...
