Construction disputes have long been identified as epidemics in the construction industry worldwide, which has become a more serious problem due to the impact of the COVID-19 pandemic. Previous studies on the dispute causes have primarily focused on country- or region-specific contexts and hence the results cannot be generalized in solving this chronic problem in a broader construction project worldwide. This study aims to explore and evaluate the critical dispute causes in construction projects through a comparative study between China and the United Kingdom. A total of 33 common dispute causes were identified through a comprehensive literature review and further consolidated by pilot surveys in the two countries. An online questionnaire survey was administered among construction professionals in China and the United Kingdom, with 170 valid responses returned for data analysis. Principal component factor analysis, mean score ranking approach, quartile analysis, and Mann-Whitney U testing were employed to identify the most critical dispute causes. Similarities and differences were mapped between the two countries. It was found that the five most critical categories of dispute causes in the two territories are: delay-related problems, lack of communication, contractual problems, site conditions, and design problems. The importance of variation in quantities, breach of contract, misinterpretation of contractual terms and conditions, and poor contract management was perceived significantly differently by the respondents in China and the United Kingdom, whereas design defects and failure to make compensation for additional work were the most critical common dispute causes in both countries. The research provides important findings for both academics and practitioners to holistically understand the similarities and differences of dispute causes in China and the United Kingdom and aids in preventing disputes more effectively in the global construction industry.

Purpose: The purpose of this paper is to summarize the latest research of BIM adoption in construction engineering and management (CEM) and propose research directions for future scholarly work. During the recent decade, building information modeling (BIM) has gained increasing applications and research interest in the construction industry. Although there have been review-based studies that summarized BIM-based research in the overall architecture, engineering and construction (AEC) area, there is limited review that evaluates the current stage of BIM-based research specifically in the CEM sub-area. Design/methodology/approach: CEM falls into the scope of AEC. It involves construction-related tasks, activities and processes (e.g. scheduling and cost estimates), issues (e.g. constructability), as well as human factors (e.g. collaboration). This study adopted a holistic literature review approach that incorporates bibliometric search and scientometric analysis. A total of 276 articles related to BIM applied in CEM were selected from Scopus as the literature sample for the scientometric analysis. Findings: Some key CEM research areas (e.g. CEM pedagogy, integrated project delivery, lean and off-site construction) were identified and evaluated. Research trends in these areas were identified, and analyses were carried out with regard to how they could be integrated with BIM. For example, BIM, as a data repository for ACE facilities, has substantial potential to be integrated with a variety of other digital technologies, project delivery methods and innovative construction techniques throughout the whole process of CEM. Practical implications: As BIM is one of the key technologies and digital platforms to improve the construction productivity and collaboration, it is important for industry practitioners to be updated of the latest movement and progress of the academic research. The industry, academics and governmental authorities should work with joint effort to fill the gap by first recognizing the current needs, limitations and trends of applying BIM in the construction industry. For example, it needs more understanding about how to address technical interoperability issues and how to introduce the integrated design and construction delivery approach for BIM implementation under the UK BIM Level 2/3 framework. Originality/value: This study contributed to the body of knowledge in BIM by proposing a framework leading to research directions including the differences of BIM effects between design-bid-build and other fast-track project delivery methods; the integration of BIM with off-site construction; and BIM pedagogy in CEM. It also addressed the need to investigate the similarities and differences between academia and industry toward perceiving the movement of BIM in construction field work. [ABSTRACT FROM AUTHOR]
