[Free PDF:🌐 https://authors.elsevier.com/a/1jIVl3IhXM-Iyn 🌐 until Aug 2024] Existing construction activity-monitoring technologies, such as CCTV cameras and IoT devices, have limitations, such as lack of depth information, 3D measurement errors, or wireless signal vulnerability. The limitations are particularly problematic for activities related to...

A value stream mapping approach to the identification of lean management opportunities for off-site construction production: A case of reinforced concrete slabs. ABSTRACT: Off-site construction (OSC), including prefabrication and Modular-integrated Construction (MiC), is gaining popularity as a school of sustainable construction methods that can im...

Mobile cranes are essential equipment in constructionsites due to their high flexibility and mobility. However,the existing sensing or monitoring methods havelimitations in monitoring mobile cranes on sites.Recently, the advent of 4D point cloud (4DPC)technology with a unique spatial-temporal data structurehas shown potential in addressing these is...

The AEC industry is undergoing a digital transformation, which is leading to partially blended learning modes in collaborative and interactive learning environments. However, online meeting software has been found to have limited capacity when it comes to teaching and learning complex geometries and systems in AEC courses. To address this issue, th...

Building information Modeling (BIM) has been applied to the whole life cycle planning of construction projects, becoming the latest “engineering brain”. Currently, researches on BIM involve various stages, but most of the review fields are relatively single and lack of systematic review and analysis. In order to comprehensively analyze the research...

[Free PDF:🌐 https://frankxue.com/#publications 🌐] Advanced information technologies such as the In-ternet of Things (IoT) and Modular Construction (MC) bring new potentials to the construction industry. The trustworthiness is critical for MC quality assurance (QA), particularly in the offshore manufacture stage. The emerging blockchain technology w...

[Free PDF:🌐 https://frankxue.com/#publications 🌐] Construction project management (CPM) is inherently complex and distributed, while digital twin and blockchain are recognized as promising solutions for information-reliant CPM. By learning from the lessons of Blockchain 1.0 and 2.0 paradigms in the literature, such as slow synchronization and faile...

The construction industry is encountering management issues, such as low efficiency, inadequate regulation and enforcement, absence of good coordination and knowledge sharing, and ineffective billing practices. Blockchain is also gaining momentum as a part of the digital transformation in the construction area and response to various challenges. Si...

Building information modeling (BIM) has been widely used as the information hub for collaborations and has increasingly been mandated in the construction industry over the past decade. From the information perspective, there have been three BIM-based exchange paradigms: (i) file-based, (ii) cloud-based, and (iii) blockchain-based. Digital twin (DT)...

Emerging advanced technologies (EAT) have been regarded as significant technological innovation which will greatly help transform the construction industry and they have been adopted widely in the prefabricated construction. As the research on emerging advanced technologies in the management of prefabricated construction (MPC) has not been involved...

Prefabrication has been widely deployed as an integral part in the intelligent construction, of which prefabrication supply chain resilience (SCR) will play a significant role. However, when an emergency [e.g., the outbreak of the novel coronavirus disease (COVID-19)] occurs, prefabrication’s life-cycle management will be seriously threatened. Besi...

Building energy consumption is the main contributor to the total energy consumption, which has an increasing impact on the environment. A systematic and comprehensive life cycle perspective assessment of building energy is crucial to maintaining project sustainability. Building energy analysis from life cycle perspective has been increasingly favou...

Effectively controlling and reducing the energy consumption of buildings is the global focus. A considerable variety of research on building energy saving (BES) had been raised in the past. However, most of the previous reviews focus on a single topic within the area, and systematic review and objective analysis are lacking. This study comprehensiv...

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...

Emerging advanced technologies (EAT) have been regarded as significant technological innovations which can greatly improve the transforming construction industry. Given that research on EAT related to the management of prefabricated construction (MPC) has not yet been conducted, various researchers require a state-of-the-art summary of EAT research...

Continuing urbanization and significant improvement of lifestyle have ushered in high demand for building floor area, inevitably leading to a rapid increase of interior decoration and renovation activities, which in turn produce a massive quantity of decoration and renovation waste (DRW). However, like many other countries with unremitting demand f...

With the adverse impacts of construction and demolition (C&D) waste on society, environment and economics, the waste management issues brought by C&D activities have received extensive attention worldwide. Advanced technologies have been increasingly adopted with the rapid development of technology to efficiently solve these issues. To handle the m...

As the core of advanced digital management application technology, BIM is widely used in various infrastructure construction. Prefabricated assembly substation uses advanced, reliable and environmentally friendly intelligent modular units to form an intensive closed substation. It takes digitization, networking and standardization of information as...

Prefabricated housing construction (PHC) will be widely recognized as a contributor to consumption reduction and sustainability enhancement if inherent drawbacks (e.g., fragmented management, poor connectivity) can be addressed efficiently. The promotion of advanced information and communication technologies (ICT) has triggered the evolvement of sm...

[ISPRS JPRS' 2020 Featured Articles] Recent advancement of remote sensing technologies has brought in accurate, dense, and inexpensive city-scale Light Detection And Ranging (LiDAR) point clouds, which can be utilized to model city objects (e.g., buildings, roads, and automobiles) for creating Digital Twin Cities (DTCs). However, processing such u...

Information technologies are increasingly adopted across the world to promote the efficiency of construction and demolition (C&D) waste management and alleviate the environmental and social effects of waste disposal.
