“…There are many shortcomings in current risk assessment methods for hoisting construction, mainly including the following reasons: (1) Complexity and uniqueness of hoisting construction: Hoisting construction involves complex operations, different site conditions, different equipment, and dynamic interactions between different elements. Many risk assessment methodologies fail to adequately capture the complexity and uniqueness of hoisting, resulting in a limited understanding of the associated risks [55,111,112].…”

Construction faces many safety accidents with urbanization, particularly in hoisting. However, there is a lack of systematic review studies in this area. This paper explored the factors and methods of risk assessment in hoisting for industrial building system (IBS) construction. Firstly, bibliometric analysis revealed that future research will focus on “ergonomics”, “machine learning”, “computer simulation”, and “wearable sensors”. Secondly, the previous 80 factors contributing to hoisting risks were summarized from a “human–equipment–management–material–environment” perspective, which can serve as a reference point for managers. Finally, we discussed, in-depth, the application of artificial neural networks (ANNs) and digital twins (DT). ANNs have improved the efficiency and accuracy of risk assessment. Still, they require high-quality and significant data, which traditional methods do not provide, resulting in the low accuracy of risk simulation results. DT data are emerging as an alternative, enabling stakeholders to visualize and analyze the construction process. However, DT’s interactivity, high cost, and information security need further improvement. Based on the discussion and analysis, the risk control model created in this paper guides the direction for future research.

“…In the 1980s, China began to promote industrialized buildings, and PBPs gradually developed [5]. However, by the 1990s, the development of PBPs remained stagnant due to the constraints of the technical level, economic conditions, and people's cognition [26]. Although China introduced PBPs decades ago, the application of PBPs still faces major problems [31].…”

“…Rose [27] used an interactive research approach to conduct a case study of a Swedish PBP and proposed solutions for three major risks. Xia et al [26] analyzed the risks faced by PBPs using EPC from the perspective of general contractors, conducted an empirical study in Nanjing, China, and found that construction and design are the main factors that determine the level of project risk.…”

“…These studies provide diversified perspectives and personalized cases for the risk research of PBPs. However, most studies were carried out in countries with relatively developed economies and prosperous construction industries [20,22,24,[26][27][28], which could not provide specific management ideas and development strategies for the risk management of PBPs in underdeveloped areas in China. The PBPs are in a complex social network environment, and various risk factors will also change due to different stakeholders.…”

Risk Network Evaluation of Prefabricated Building Projects in Underdeveloped Areas: A Case Study in Qinghai

Prefabricated building projects (PBPs) face more risks than traditional construction projects, especially in underdeveloped areas. This study takes Qinghai Province as a study case. Social network analysis (SNA) is adopted to develop a risk network of PBPs, and nine core risk factors and five key risk relationships are identified. Risk effect detection reveals the effectiveness of risk response strategies. The research shows that PBPs in underdeveloped areas are still in the early stage of development, and developers generally lack a leading role. There are prominent problems in the design stage of PBPs, so the stakeholders pay special attention to them. In underdeveloped regions, the development of PBPs must rely on the strong promotion of the government. Limited by natural and economic conditions, the market mechanism of PBPs in underdeveloped areas is not perfect, and policy regulation greatly affects the spread of the risk network. Therefore, local governments need to actively introduce corresponding supportive policies and mobilize the enthusiasm of stakeholders. This is the first study to consider the risk within the life cycle of PBPs in underdeveloped plateau areas. This study expands the research system of risk management of PBPs and provides valuable risk response strategies for the stakeholders.

The assembled concrete structure is a common construction solution in the current building industry, and it is debatable how to further improve the construction efficiency of the pointed claw assembled concrete structure. The study proposes a grey clustering method based on the improved OWA operator as a means to obtain more effective construction evaluation indicators. In performance tests, it was shown that the grey clustering method under the OWA operator optimisation is more capable of computing features for large amounts of data than traditional grey clustering, with an execution time of less than 200s. In the application tests of the construction scheme, the study showed that the proposed optimisation scheme has a more effective safety evaluation, shorter construction period and lower resource consumption. These results show that the use of grey clustering is effective in optimising the construction of assembled concrete structures, and that the optimised solutions show better reduction in construction time and resource utilisation than traditional construction solutions, so that the rational use of grey clustering in assembled buildings will help the construction industry to achieve greater efficiency in construction.
