Construction 4.0: what we know and where we are headed?

Abstract

The last decade has witnessed unprecedented changes in the technologies and processes involved in the construction industry. The philosophies associated with Industry 4.0 now reverberate in construction 4.0. Digitalization and interconnectivity in the cyber-physical systems of the sector are at the heart of such transformation. Construction 4.0 brings to the table a plethora of technologies and associated processes over the construction project lifecycle. The current study performs a state-of-art literature review to summarize the knowledge advancement in construction 4.0. A layered conceptualization spanning across project lifecycle utilizing the people-process-technology dimensions is presented to summarize the current understanding of Construction 4.0. The cyber-physical space is classified into the physical, digital tool, data, and core data security and interoperability layers. The inter-layer and intra-layer interactions and information flows are then conceptualized based on the extant literature, including the human interaction and interventions. The people-process-technology dimensions were discussed across the project lifecycle through interactions in these layers. It is observed that Construction 4.0 is set to be driven by data creation, data flow, data transformation, and data storage across the project lifecycle to ensure a collaborative environment across the stakeholders who interact and associate with different layers of Construction 4.0. The article finally presents challenges with the current formulations and explores ways to further our knowledge in the area.

Construction of Heritage Digital Resource Platform Based on Digital Twin Technology

“…Most of the research content revolves around the theoretical construction of digital protection, the development of key technologies, or the application and practice of digital technology in the display and dissemination of cultural heritage. Singh et al pointed out that emerging technologies such as VR and AR have the potential and advantages of e cient and low-cost ways to preserve and disseminate cultural information [3]; Rhee et al applied AR and 3D computer graphics technology to the cultural relics enhanced display system and analyzed its usability [4]; Jahanger et al used a technology acceptance model to analyze the cultural heritage movement and the acceptance of augmented reality applications [5]; Karimi et al proposed an augmented reality-based interactive virtual guide for visiting archaeological sites [6]; Karmakar et al explored in their doctoral dissertation the application of augmented and virtual reality technology in museum education through computer-supported collaborative learning [7]. In the "double wall dialogue," Dy et al introduced the research results of the archaeological demonstration of Bodward Fortress using airborne laser scanning technology and described the motion recovery structure technology for accurately generating 3D data [8].…”

Automated route planning for construction site utilizing Building Information Modeling

“…4D BIM can manage and integrate complex time-dependent variabilities with 3D model elements (Li, Xu and Zhang, 2017). BIM can handle and transfer information effortlessly across the project lifecycle (Karmakar and Delhi, 2021). Even though it makes BIM a potential candidate for route planning, it should be aided with optimization techniques to generate the optimal result.…”

Digital technologies and data-driven delay management process for construction projects

“…Substantial research has been carried out on automated technologies in construction projects, such as 1) the use of remote sensing technologies from 2D photo-feature extraction to 3D laser scanners; 2) Radio Frequency Identification (RFID) tags for automated data acquisition in construction job sites; 3) Ultra-wideband (UWB) for data detecting, acquiring, and monitoring; and 4) access to realtime data Industry 4.0 focuses on digital technologies with the help of interconnectivity through using the Internet of Things (IoT) applications/technologies in the supply chain, safety, and project management concepts (Li et al, 2016;Asadi et al, 2018;Al-Saeed et al, 2019;Ghosh et al, 2020). Karmakar and Delhi 2021 have summarised the knowledge advancement of construction 4.0 to present technologies, and process conceptualisation which is nowadays associated with Industry 4.0 reverberate in construction 4.0 (Karmakar and Delhi, 2021). However, IoT-based sensors and technologies often lead to the generation of large datasets captured through construction scheduling, tracking, localisation, and 4D/5D-BIM in construction projects (Benjaoran and Bhokha, 2010;Omar and Nehdi, 2016;Karmakar and Delhi, 2021).…”

From a scheduling point of view, automated technologies mitigate the potential negative impact of schedule delays and cost overruns, but they can also help improve safety and productivity on site (Cheng et al, 2017;Fujisaki, 2019;Yoshigai and Fujisaki, 2020).…”
