China’s construction industry developed rapidly and safety production has become a vital issue. Improving the safety behavior of construction workers is an important measure to effectively decrease construction safety accidents. At present, a New Generation of Construction Workers (NGCWs) born after 1980 has gradually become the main force of construction companies in China and the special group characteristics coming from the intergenerational difference may make them behave differently in safety-related activities, therefore, it is very important to study how to promote their safety behavior. This paper aimed to explore the influencing mechanism of job satisfaction on the safety behavior of NGCWs and examine the mediating role of safety knowledge sharing and work engagement. Confirmatory factor analysis and structural equation modeling analysis were applied to test the theoretical model. Empirical research results indicated that job satisfaction can effectively promote safety behavior through safety knowledge sharing and work engagement. Safety knowledge sharing plays a complete mediating role between job satisfaction and safety compliance behavior, as well as between job satisfaction and safety participation behavior. Moreover, work engagement plays a complete mediating role between job satisfaction and safety participation behavior, which can provide valuable management references for China’s construction companies to strengthen their safety behavior.

Building Information Modeling (BIM) technology has promoted the development of the architecture, engineering, and construction (AEC) industry, but has encountered many barriers to its application in China. Therefore, identifying the barriers to BIM application and capturing their interactions are essential in order to control and eliminate the determined barriers. From this standpoint, 23 BIM application barriers were identified through a literature review and expert interviews. Furthermore, the interactions among them were determined based on the Delphi method, which was the foundation for establishing the BIM application barrier network (BABN). Then, the software Pajek was employed to construct the network model and reveal its topological characteristics based on complex network theory, including degree, betweenness, eigenvector, clustering coefficient, network diameter, and average path length. As indicated by the results, BABN possesses scale-free network property because its cumulative degree distribution obeys power-law distribution. BABN is also a small-world network, due to its relatively high clustering coefficient as well as small average path length, implying that barrier propagation in BABN is fast. In addition, the results are discussed and recommendations are proposed. This research will help BIM stakeholders to develop coping strategies to control and eliminate BIM application barriers for the sake of driving BIM sustainable development.Sustainability 2020, 12, 3190 2 of 22 showed that applying BIM can reduce errors in the project, which reduces the cost compared to the up-front cost brought by applying BIM. As a digital technology, BIM can reduce cost throughout the building's lifecycle [5]. It can be utilized to support design, procurement, fabrication, construction, operation, and maintenance, such as cost management, time management, risk management, resource management, facility management, and sustainable applications. In short, BIM offers the potential to help transform the construction industry and boost productivity in the AEC industry [6].As the application of BIM helps to promote the sustainable development of the AEC industry, many governments are actively promulgating policies to accelerate the process of BIM adoption, including the United States, China, the United Kingdom, Singapore, and others [7]. The government has been an active advocate of BIM application. The Chinese AEC industry is one of the biggest and most important markets in the world, and it also plays a pivotal role in China's economy. Recently, the Chinese government has been actively promoting the development of BIM technology in China. The study conducted by Lin and Zhang [8] indicated that China's national government, local government, and association issued a total of 58 BIM-related policies from December 2013 to December 2017, and the number of polices demonstrated a typical exponential growth trend. It can be inferred that the relevant state agencies will increasingly be issued along with the development of BIM.Co...
