Hong Kong is a densely populated city with high-rise developments, and as in other metropolitan cities, the amount of waste generated from construction projects in the city is increasing annually. The capacity of existing landfills is expected to be saturated by the 2020s. Construction waste management has been implemented for years but the performance is still not satisfactory. The aim of this research paper is to explore and formulate strategies and measures for effective construction waste management and reduction in highly urbanized cities such as Hong Kong. A desktop study on construction waste management practices was carried out for a preliminary understanding of the current situation in Hong Kong. Semistructured interviews and focus group meetings were further conducted to shed light on how to improve construction waste reduction and management in Hong Kong. The main contributions of this research study are the potential short-term, medium-term, and long-term strategies, which are related to the design stage, tender stage, construction stage, and government support. The five major strategies recommended are financial benefits to stakeholders, public policies in facilitating waste sorting, government supports for the green building industry, development of a mature recycling market, and education and research in construction waste minimization and management.

Off-site construction as an industrialized construction method has become a hot topic in addressing climate change. Government policies have been formulated to promote the development of off-site construction in China. Previous studies have found policy benefits for the development of off-site construction, but few studies have explored its effects on decision-making developers' adoption of off-site construction. This study aims to quantitatively verify the effect of policy on developer's implementation of off-site construction and to explore practical paths for encouraging developers to implement off-site construction using partial least-squares path analysis. The results show that environmental policies have significant direct effects on developer's implementation of off-site construction. In contrast, demand-side and supply-side policies only indirectly affect developer's implementation of off-site construction through their effects on the market environment. Moreover, the market environment's mediating role was verified, suggesting that the market environment should be fostered to improve developer to adopt off-site construction method and then promote off-site construction development. Furthermore, this study explored ways to stimulate developer's implementation of off-site construction through environmental policy instruments by unpacking the market environment's mediating effect.

Gated communities are the most popular residential pattern in the urban areas of China. However, along with the increasing population density in urban areas, this pattern may have negative influences on people’s daily lives, such as traffic jams. To avoid the negative influences, the government has encouraged residents to open their gated communities; however, few positive actions have been taken. With this background, this study aims to explore the key factors in residents’ willingness to open their gated communities. To start with, a total of 26 potential factors were identified based on a comprehensive literature review. Then, a questionnaire was designed and distributed to collect empirical data. Furthermore, logistic regression was employed to analyze the collected data. Based on the derived results, it was revealed that concerns are different between male and female residents. Male residents regarded “community safety” and “property management” as having a significant impact on their decision to open a gated community, while female residents paid more attention to the factor of “proprietary equity”. The results of this study could provide valuable references that enable the government to better understand residents’ underlying concerns and to make relevant policy decisions.

In recent years, building information modeling (BIM) has been receiving growing interest from the construction industry of China. Nevertheless, although BIM has many foreseeable advantages, many studies claimed that these advantages have not been sufficiently achieved in practice at the current stage. In this circumstance, it is interesting to investigate what really drives the adoption of BIM. Based on Ajzen’s theory of planned behavior (TPB), a hypothetical model which involves nine latent variables is initially established. Then, a questionnaire is designed and distributed to the construction professionals in the Chinese context. After reliability and validity analysis, the goodness-of-fit of the initial model and the related theoretical assumptions are tested through structural equation modeling (SEM). Based on the modification indicators, a modified model is finally derived. Results show that economic viability and governmental supervision are the most critical factors that influence construction professionals’ BIM adoption behavior in China, sharing weights of 0.37 and 0.34, respectively, whereas other factors play limited roles in this regard. The research findings revealed from this study can provide insightful references for countries that intend to promote BIM adoption in a similar circumstance.

China has enacted numerous green building policies (GBPs) to promote green building (GB) development in the past decades. Investigating the evolution characteristics of China’s GBPs is significant for the future optimization of the GBP system. However, few studies on this topic have been conducted. To bridge this research gap, this paper adopted the methods of bibliometric analysis and text mining to probe the dynamic evolution of the GBPs in China. Firstly, a total 199 collected policies from 1986 to 2019 were grouped into five stages according to the Five-Year Plan. Then, the topics emphasized in different stages and the cooperative relationships among policymaking agencies were discovered by mapping and visualizing the co-word network and co-author network. Based on the derived results, an in-depth discussion was further conducted from five aspects: targets, objects, instruments, GB performance indicators, and the collaboration structure of policymaking agencies. It was revealed that the topics of GBPs evolved from macro to specific, and the types of policy targets, objects, instruments, and GB performance indicators evolved from few to multiple. Additionally, the collaboration structure of policymaking agencies went from dispersive to centralized. This study sheds lights on the dynamic evolution of China’s GBPs and provides valuable references for other countries in need.

Adopting the form of the dynamic μ(Fr,h) basal friction law and introducing a second-order viscous term into the Saint Venant-type equations, we simulated two-dimensional granular roll waves generated in a rectangular chute applying the second-order-accurate total-variation-diminishing MacCormack scheme. Consistent with previous findings, we found that the amplitude and wavelength of the wave increased with transit distance. Although the μ(Fr,h) dynamic basal friction law is the more influential factor in shaping the waves, introducing a viscous term slightly reduces the wave peaks. A sensitive analysis indicates a quadratic relationship between wave peak height and the coefficient in the depth-averaged viscosity with ν≤2.4 × 10−2 m1.5/s. In the numerical simulation of roll waves subject to initial perturbations of different magnitudes, three stages in their evolution (namely, emerging, ripening, and attenuating) are evident from their difference in transit behavior. In the emerging stage, the normalized maximum height of the roll waves increases exponentially during propagation. In the ripening stage, this height grows linearly with transit distance whereas the growth rate decreases with the strength of the initial perturbation. During the attenuating stage, the maximum roll-wave height forms a hump in the upstream region where the waves attenuate. Roll-wave peaks and troughs for all three stages tend to approach equilibrium heights further down the chute. Subcritical flow roll-wave simulations show that as flow speed decreases, a reverse transformation pattern is found; specifically, the amplitude and wavelength of the wave decrease further down the chute.

Prefabricated building projects (PBPs) have been recognized as an effective method for reducing energy consumption, carbon emissions, and resource depletion. Various information, material, product, service, and fund flows exist in PBPs, leading to high requirements of information exchange and collaboration among the multiple stakeholders. The Internet of Things (IoT) platforms are powerful tools that can support these requirements. However, the IoT platforms have not been extensively applied in industry, which is a significant bottleneck in PBP promotion. Stakeholders are the entities that make decisions on the use of IoT in PBPs and play an important role in its successful implementation. This study proposes a game-theory-based model to reveal the mechanisms of stakeholders’ decision-making on the adoption of IoT platforms in PBPs. The game analysis results reveal the optimal selection strategies of critical stakeholders regarding the IoT adoption under different conditions. The market penetration rate (MPR) of IoT platforms in the PBP markets has been found to be a critical factor that influences the decisions of critical stakeholders considerably. The results of this paper could provide valuable policy implications (i.e., improving the market penetration rate of IoT platforms by developing pilot projects, motivating clients to use the platforms in PBPs, and providing relevant IoT educational programs) for promoting the adoption of IoT in PBPs, which is of benefit to enhance PBP development and further improve energy and resource conservation.

Construction management can be regarded as a complex and dynamic system. In recent years, system dynamics (SD) has been widely applied to solve the complex and dynamic problems in the construction management. However, there is a lack of a scientometric analysis to investigate SD applications in construction management from an objective perspective. To fill out this research gap, this study retrieved a total of 222 relevant articles from the Scopus database. Then, VOSviewer was employed to analyze the collected literature from five aspects (i.e., co-authorship, published journals, co-occurring keywords, article citations, and regions). Based on the analysis results, four mainstream research themes were identified and discussed, including “risk management”, “waste management”, “energy management”, and “construction productivity”. In addition, future research directions, such as “construction risk allocation in PPP projects”, “evaluating the economic feasibility of construction waste landfilling centers”, “identifying the variables affecting lighting infrastructure energy consumption”, and “assessing construction productivity for technology-intensive activities”, were proposed. The contribution of this study lies in that it helps both scholars and practitioners to solve the complex and dynamic problems in construction management.

Construction and demolition (C&D) waste accounts for a large proportion of solid waste, thus effective C&D waste management is essential for promoting sustainable development. In Hong Kong, the government has promulgated a series of policies to encourage related stakeholders to implement effective C&D waste management. However, the overall status remains not satisfactory and has a great potential for further improvement. In this circumstance, the aim of this study is proposing solutions for further improvement of effective C&D waste management in Hong Kong. Based on a comprehensive content analysis of seven selected countries and two rounds of focus group meetings with local experienced professionals, prevailing C&D waste management policies and successful practices were identified and their feasibility of implementation in Hong Kong was discussed. Results revealed that non‐inert waste recycling is a key for improving the C&D waste management in Hong Kong to a higher level. A “3R + I” principle was suggested to be implemented in Hong Kong instead of the currently employed “3R” principle. Four solutions, namely promulgation of more specialized regulations, adoption of advanced recycling technologies, development of mature recycling markets, and implementation of high landfilling costs, were identified as the key directions for future improvement of C&D waste management in Hong Kong. The identified C&D waste management policies and the research methods used in this study can be employed in other countries or regions which are at different C&D waste management levels and economic status to form their own applicable policy framework.

Green building (GB) incentives help address the barriers in GB development. After years of practice, the GB market is becoming mature; thus, these incentives should be adjusted to adapt to the market transformation. However, adjusting incentives can affect stakeholders' motives and concerns, which in turn influence stakeholders' attitudes towards green buildings. Therefore, going back to the basics and understanding how an incentive scheme works before implementing any adjustment are important for policymakers. This study aims to reveal how incentive mechanism design affects stakeholders’ choices of GB levels in tangible and intangible ways. The Gross Floor Area Concession Scheme implemented in Hong Kong is selected as a case study. Cost–benefit analysis, particularly transaction cost, and the analytical hierarchy process method are used to evaluate the costs and benefits in terms of monetary value and importance. Then, a causal loop diagram is constructed to explain the incentive mechanism. Results show that although actual costs and benefits are more important than hidden ones, transaction cost can be a decisive factor for selecting GB levels. Cost–benefit analysis with transaction cost considerations should be conducted to improve GB incentives. In addition, fast sales of high levels of GB can be a critical compensation for extra costs. Alternatives for improving incentives are also provided based on the findings. This study helps enrich the incentive mechanism for promoting high levels of GB. It provides empirical evidence on the magnitude of transaction cost and proves the soundness of conducting a holistic cost–benefit analysis by incorporating transaction cost.

Safety hazard identification is an essential method for mitigating non-fatal fall injuries and improving construction workers’ safety performance. Current safety hazard identification methods mostly rely on experts’ judgment to identify hazards, and thereby they are unable to continuously identify hazards in the diverse and dynamic nature of the construction environment. To identify safety hazards and improve workers’ safety performance, a better understanding of the relationship between workers’ gait disruption patterns and the presence of a safety hazard is vital. Toward achieving this goal, the objective of this study was to propose a non-invasive approach to examine the feasibility of using workers’ gait disruption patterns to identify safety hazards among construction workers. To test the hypothesis of this study, ten asymptomatic participants conducted four simulated experiments in a laboratory setting to examine the feasibility of the proposed approach. The participants’ gait disruption patterns were collected using a wearable insole pressure system to compute five gait variability parameters and a gait abnormality based on ground reaction force (GRF) deviation. The results showed that workers’ gait disruption patterns measured by the gait abnormality based on GRF deviation values are highly correlated with the location of hazards, which indicated that workers’ gait disruption patterns in hazardous areas are more distinct than non-hazardous areas. The findings of this study can serve as the basis for developing a non-intrusive and automated wearable insole pressure system that uses workers’ gait disruption patterns as a useful data source to enable safety manager to identify safety hazards in construction.

Tunnel engineering is affected by a variety of factors, which results in large detection errors in tunnel engineering. In order to improve the monitoring effect of tunnel engineering, based on BPNN and MARS machine learning regression algorithm, this research constructs a tunnel engineering monitoring and prediction model. Moreover, the gray residual BP neural network designed in this study uses a series combination, and the residuals obtained from the gray model are used as the input data of the BP neural network, and the output of the combined model is used as the prediction result. By applying the monitoring data of the convergence of the upper surrounding of the tunnel surface section and deformation of the arch subsidence, it is verified that the proposed method based on the combined model of BPNN and MASR can predict and analyze the tunnel deformation monitoring data very well.

In recent years, with the development of green building and the increase of health awareness, the concept of healthy building has been proposed. Recently, studies have been made on developing healthy residential buildings; however, few attentions have been paid to the development of healthy dormitories. To bridge this research gap, this paper aims to investigate the crucial aspects of developing a healthy dormitory. Based on the Maslow’s hierarchy of needs, three influencing aspects which include 17 measurement indicators are identified. Questionnaire surveys are subsequently conducted to collect students’ perceptions on the identified indicators. After a structural equation modeling (SEM) analysis, the relationships between the three influencing aspects are analyzed. The research findings show that building performance, bodily sensation, and humanistic environment must be taken into account in the development of a healthy dormitory. In addition, it is revealed that building performance has a significant impact on bodily sensation, while bodily sensation has a significant impact on humanistic environment. However, building performance is found having little impact on humanistic environment. The findings of this study could provide useful information for the construction of healthy dormitories.

Prefabrication is a technology that can reduce the material consumption during the construction process. Thus, it is regarded as a technology that be of assistance in the pursuit of sustainable development in the construction industry. In China, a series of policies has been formulated to promote the implementation of prefabrication; however, the effectiveness of these policies has not been investigated. The aim of this paper is to evaluate the effectiveness of the current prefabrication incentive policies in China. To achieve this research aim, a policy framework was first developed in order to understand the existing policies. Then, four indicators—namely, the number of prefabricated component production enterprises, the prefabricated floor area, the prefabricated building market size, and the expected prefabricated building area ratio—were selected to evaluate each policy’s effectiveness. It was found that the growth rates of these four indicators had increased slowly, and had even shown declining trends before 2015; however, with the incentive policies promulgated after 2015, the growth rates have increased. This study is of value not only in helping readers to understand the existing framework of incentive policies in China, but also in revealing the effectiveness of the identified prefabrication incentive policies. These research findings can also provide insights useful for policy formulation in other jurisdictions for the promotion of prefabrication.

Visualization is one of the main features of Building Information Modeling (BIM). It has many advantages throughout the lifecycle of a construction project, and it has become a timely research topic in recent years. However, no attempt has been made to give a holistic understanding of the existing BIM-based visualization research status. Thus, this study aims to conduct a scientometric analysis of the existing BIM-based visualization literature and to gain a snapshot of the research status during the period 2010–2019. A total of 255 articles were abstracted from the Scopus database. Then, the VOSviewer program was employed to visualize the research status from the perspectives of scholars, countries/regions, journals, articles, and co-occurring keywords. Results revealed that Wang X. published the greatest number of articles, while Cheng J.C.P. received the greatest average normalized citations. Furthermore, Automation in Construction was identified as the most influential journal and the article “Building information modeling (BIM): trends, benefits, risks, and challenges for the AEC industry” was the most cited paper. Through the keywords co-occurrence analysis, “virtual reality” and “visual programming language” were identified as the emerging themes in this field. The research findings can provide both researchers and practitioners with a better understanding of the status quo and trends of the BIM-based visualization research.

Culture-led regeneration projects (CRPs) have been identified as an effective means for enhancing the sustainable development of cities. Related topics have been investigated; however, relatively little information is known about what factors are critical for achieving success in these kinds of regeneration projects. Based on a literature review and five case studies, this study contributes to the body of knowledge by identifying 25 critical success factors (CSFs) for managing CRPs in China. A questionnaire survey was designed to evaluate the relative importance of these factors from practitioners’ and researchers’ perspectives. In addition, a factor analysis was carried out to group these CSFs into five categories, namely government policies and culture-led regeneration strategies, stakeholder management and financing support, technical solutions for CRPs, social security, and industry development. The results demonstrated that cultural value management, integrating cultural development with urban planning, adopting sustainable development principles, reconstructing the city image and brand, and the availability of culture-led planning methods played the most important roles in the success of CRPs. The findings of this study can help practitioners enhance their regeneration project performance.

Effective waste management is an important aspect of green building development. However, a number of studies find that construction waste minimization actions are not satisfactorily performed in practice. Thus, it is of significance to identify the driving factors that influence construction practitioners' waste minimization behavior. This paper aims to explore the driving factors by comparing the affecting factors and construction waste minimization behavior between Hong Kong and Shenzhen. Firstly, through a comprehensive literature review, potential affecting factors were categorized into five groups: background information variables, construction waste minimization intentions, economic viability, governmental supervision, and project constraints. Based on the identified factors, a questionnaire was initially designed and then refined through a focus group meeting with three experienced experts. A total of 166 questionnaires were collected and non-parametric tests (Mann-Whitney U Test and Kruskal-Wallis Test) were conducted to investigate the underlying driving factors. Results revealed that background information variables play insignificant roles in construction waste minimization. Compared with other affecting factors (i.e., waste minimization intentions, governmental supervision, project constraints), economic viability is the most important driving factor that determines construction waste minimization. Results suggested that local governments should make policies that increase practitioners' profit, rather than just increasing their intentions or regulating waste management behavior.

The construction industry consumes substantial water resources. Thus, there is a necessity to adopt effective water-saving measures to reduce water consumption in construction projects. The aim of this paper is providing a strategic framework of water-saving measures for different phases of a construction project. To start with, the prevailing green building rating tools were investigated to explore the alternative water-saving measures. Then, a comparative analysis utilizing relative significance indexing was conducted to identify the foci of water-saving measures in various green building rating tools. Based on the derived results, ten water-saving measures, namely rainwater harvesting, usage of recycled water, NEWater, water-saving technologies, water-saving devices, water-saving efficiency, water monitoring system, monitoring of major water uses, leak detection, and continuous water monitoring, were identified. These measures were further categorized into three strategic aspects, such as water sources substitution, water consumption reduction, and water use monitoring. Based on the results, a strategic framework was developed for reducing water consumption and improving water use efficiency. The developed framework can serve as a systematic guideline for formulating water-saving schemes in different stages of construction projects.

With the rapid development of the economy, people are paying more and more attention to the environmental problems. In this circumstance, the concept of a circular economy is proposed for making efficient use of resources and minimizing the production of waste and other emissions. Each year, the construction sector consumes a vast volume of resources and makes impacts on the environment. To align with the development of the circular economy, the concept of green building is proposed. In China, though the concept of green building has been promoted for decades, the development status is far from optimistic. Thus, this paper aims to investigate the barriers that hinder green building development (GBD) in China. Through a systematic review and semi-structured interviews with experienced industrial practitioners, 24 potential barriers of GBD in China were identified. A questionnaire survey was then conducted for data collection. After descriptive and inferential statistical analyses, a partial least squares structural equation model (PLS-SEM) was established to investigate the impacts of different barriers on GBD. Results showed that the lack of policy and industry guidance, the immature market environment, and the lack of environmental awareness are the most important GBD barriers in China. This research can assist stakeholders in better understanding the status of GBD in China and enable decision-makers to formulate appropriate strategies to promote green building.

With the rapid development of urbanization, more and more people are willing to improve their living conditions, thus substantial attention has been paid to residential renovation in China. As a result, large quantities of renovation waste are generated annually which seriously challenge sustainable urban development. To effectively manage renovation waste, accurate prediction of waste generation rates is a prerequisite. However, in the literature, few attempts have been made for predicting renovation waste as renovation activities vary significantly in different cases. This study offers an approach to estimate the amount of renovation waste based on the vacancy rate and renovation waste generation rates at a city level. The grey system theory was applied to predict the amount of renovation waste in Shenzhen. Results showed that the amount of renovation waste would reach 135,620 tons in 2023. The research findings can provide supportive information to relevant stakeholders for developing a renovation waste management framework.
