“…This framework provides quality control and decision-making support in the design, manufacturing, and on-site assembly stages. (31) In addition, the on-site assembly process is also delayed by uncertainties due to safety issues. Currently, safety issues mainly focus on on-site construction work space monitoring and safety risk management.…”

This paper focuses on how to use IoT technologies to monitor the project implementation process in prefabricated building (PB) construction, which will help optimize the construction schedule and ensure the quality and safety of PB construction. Although IoT monitoring can obtain a large amount of data during construction, the challenge is how to convert these data into intelligent information needed for feasible decision-making. Therefore, we need to clarify the key factors requiring monitoring during construction and how to use these data to make decisions. In this paper, we analyze the whole process of PB construction, comprising five phases: pre-construction, off-site manufacturing, delivery, on-site assembly, and finishing. Through mathematical model formulation to discover the key factors that affect the construction implementation process, we clarify the monitoring data that need to be obtained by IoT technologies. Using these monitoring data, it is possible to make judgments on process abnormalities, promptly give alarms, make proactive adjustments, and optimize the construction implementation process, thus achieving the goal of ensuring project quality and construction safety.

“…Valero et al [9] introduced the application of RFID technology in tracking the status of PCs and Lee [10] designed a conceptual framework for prefabricated building construction management systems, integrating BIM, 3D laser scanning, IoT, cloud computing and other information technologies, to improve the efficiency and quality of prefabricated building construction management. Wang et al [11] proposed a conceptual framework of an Intelligent Construction System for Prefabricated Buildings based on the IoT (ICSPB-IoT) and proved the feasibility of the realization of ICSPB-IoT through case studies. Professor Ma and his team, on the basis of overall building information management, also conducted research on prefabricated buildings and put more emphasis on intelligence on the basis of informatization [12].…”

The hoisting of prefabricated components (PCs) is a key step during the construction of prefabricated buildings. Aiming at the problems existing in the control of PC hoisting, an innovative hoisting management system framework based on the digital twin (DT) is established in this paper. The system framework comprehensively utilizes the building information model (BIM) and Internet of Things (IoT) to establish a digital twin model (DTm) for PC hoisting control and uses Dijkstra’s algorithm to conduct hoisting route planning according to the BIM data in the model. Meanwhile, long-range radio (LoRa) technology was used for data acquisition and transmission to monitor the movement state of the PCs in the hoisting process. By testing it in a prefabricated building project, the DT control method was conducted to realize the functions of real-time information collection, hoisting path planning and PC positioning, which proved the feasibility and effectiveness of the method. As a key technology to realize intelligent manufacturing, DT has been widely studied in academia. The DTm of the hoisting process of PCs is established in this study; it improves the level of intelligent management of prefabricated building construction and provides a new idea for intelligent building construction.

“…In particular, to promote intelligent construction in engineering construction, high-quality development requires the construction industry to take building industrialization as a carrier (Li et al, 2018). Intelligent construction is an innovative construction model that combines digitalization and engineering construction, which helps break through the bottleneck of information integration and interaction in prefabricated buildings (Wang et al, 2020;Wen, 2021). A priority for intelligent construction to assist in the development of construction industrialization.…”

Digitalization drives the arrival of the era of intelligent construction, which greatly affects the development of construction industrialization. Due to the collaborative barriers between intelligent construction and building industrialization (ICBI), it is difficult for construction enterprises to participate in the actual engineering projects in this work. Achieving the collaborative development of ICBI has become a way to transform and upgrade the construction industry, and it has attracted more and more attention. However, the existing literature lacks consensus on the collaborative development of ICBI affecting the construction industry. In order to promote the theoretical research on the collaborative development of ICBI, this paper proposes a “mi” shaped conceptual framework so that readers can understand the operation law of ICBI collaboration and promote its healthy development. Therefore, based on the synergy theory, this paper extracts the contents of stakeholders’ collaboration, industrial collaboration, structural collaboration, construction technology upgrading, factor endowment upgrading, innovation service upgrading, and construction process upgrading. These seven items are summarized into four dimensions: dual drive, resource supply, collaborative operation, and trust guarantee, which indicate the direction of ICBI collaborative development. The research results will help to realize the industrialization of new buildings and promote the sustainable development of the construction industry.
