With the development of engineering technology, building information modeling (BIM) has attracted more and more attention and has been studied by many experts on building energy consumption in recent years. It is necessary to analyze and forecast the application trend and prospect of BIM technology in building energy consumption. Based on 377 articles published in the WOS database, this study adopts the technique of combining scientometrics and bibliometrics to obtain relevant research hotspots and quantitative analysis results. The findings demonstrate that the building energy consumption field has made extensive use of BIM technology. However, there are still some limitations that can be improved, and the use of BIM technology in construction renovation projects should be emphasized. This study can help readers better understand the application status of BIM technology and its trajectory of development with regard to building energy consumption, providing a valuable reference for future research.
There are many unpredictable circumstances during the implementation process of a water conservancy project, which often cause financial loss, increased construction costs and schedule delays. This paper investigates the influence factors for water conservancy project cost control. The present study used the factor analysis method to extract the major cost control influence factors, and performed a correlation analysis to clarify the relationship between these cost control influence factors and the sub-factors under each factor. Several water conservancy project practitioners were invited to analyze the sub-factors of the cost control influence factors and to provide some strategic suggestions in terms of minimizing the impact of the influence factors. The results of the study illustrate that in construction, water engineering contractors who want to reduce costs need to focus on the lack of a clear definition for the scope of works, subcontractors’ insufficient ability to perform the work, site construction conditions and the escalation of the construction material cost. The correlation analysis demonstrated that unreasonable requirements from the supervision unit and unfair standpoints of the supervision unit are highly correlated; the insufficient mobilization ability and lack of management capability of the subcontractor are medium correlated; the site construction conditions and the lack of a clear definition for the scope of works are medium correlated; and the escalation of the construction material cost and shortage of construction materials are medium correlated. This facilitates future water works contractors to identify the underlying causes of cost increases.
Construction safety climate (CSC) has become an important part of the construction safety research field in recent years. This paper analyzes the current research status, hot spots, and trends of CSC by sorting 531 articles in the Web of Science (WOS) database from 2017–2022 through the visualization software VOSviewer. The study shows that (1) China has made significant contributions to CSC research, with Chan, A.P.C. being the most published and cited scholars in recent years, respectively, laying the foundation for CSC; (2) the hotspots of CSC include two main directions, namely research on CSC dimensions and evaluation systems, and the combination with cross-cutting themes (such as safety culture, safety performance, and safety behavior); (3) the research on CSC and safety behavior has become one of the most prominent research directions, mainly divided into two aspects, namely workers’ causes and external causes; (4) a warning system of safety behavior for construction workers through CSC is still worthy of exploration. The results of this study could help scholars clarify the research lineage and current situation in this field and to grasp future research directions.
The goals of sustainable development are constantly negatively impacted by infrastructure initiatives. The importance of these projects in advancing the economic, social, and civilizational growth of the country will, however, prevent their construction from being stopped. The overall construction of the project is related to the scientific and unbiased assessment of an infrastructure project’s sustainability throughout the decision-making stage. Based on the references documents, this paper establishes an index system for evaluating an infrastructure project’s sustainability from three aspects: environment, economy, and society. In the assessment process, the cloud model was used to describe the various attribute values of infrastructure project sustainability, which achieved the uncertainty measures for infrastructure project sustainability, and a cloud model-based assessment method for infrastructure project sustainability was proposed by modifying the attribute value by the penalty factor. Finally, an assessment method for infrastructure project sustainability based on the cloud model was proposed after the attribute values were modified by using a continuous interval argument ordered weighted average (C-OWA) operator. The model carries out an overall sustainability assessment by generating a synthesized cloud with the weight to calculate the similarity of assessment factors, which takes the randomness, fuzziness, and uncertainty of expert qualitative assessment into account, and uses the analytic hierarchy process (AHP) method and the C-OWA operator to determine the weight of the sustainable index and the aggregation of the expert scoring interval. A case study was conducted to clarify how this strategy was applied. The study provides a valuable and useful tool for the operational stage to assess the achievability of municipal infrastructure projects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
