Multi-Agent Decision-Making in Construction Engineering and Management: A Systematic Review

Extended reality (XR) technologies are increasingly being used as a novel research instrument to facilitate scientific inquires in the construction engineering and management (CEM) domain. By allowing humans to interact with immersive environments in controlled and monitored experimental settings, XR technologies have opened new opportunities for researchers to conduct CEM research involving human participants or concerning human behavior. Yet, XR-enabled research, as an independent, rigorous methodology for the CEM domain, is still underexplored. This paper serves as an effort to build an organized knowledge base and workflow for using XR technologies in various CEM research areas and methodological contexts. The paper first investigates the status quo of XR-enabled CEM research, by identifying current research areas in the CEM domain where XR technologies are considered the preferred or recommended methodological solutions. A process model for XR-enabled research is then proposed, with actionable recommendations about how XR-enabled research should be planned, designed, implemented, analyzed, verified, and validated. This process model is demonstrated with two illustrative case studies. Last, the paper discusses the philosophical, methodological, and technological roots of the evolution of XR-enabled CEM research and describes our vision of more enabling, adoptable, and value-adding XR-enabled research in CEM in the near future.

Long-term Trends in Construction Engineering and Management Research in Korea

The use of blockchain technology in construction engineering and management (CEM) is increasing, yet current presentations of blockchain-based data management processes (DMP) are considered too primitive to encourage the technology’s broader diffusion in CEM. This research aims to provide a set of guidelines for visualizing blockchain-based DMP in CEM. First, a conceptual model is proposed to guide the research design. Next, 49 cases published in scholarly papers are reviewed, revealing an increasing use of dashboards to visualize blockchain-based DMP. Then, four challenges for visualizing blockchain are identified, namely, data diversity, visualization tools, visualization mediums, and visualization domain. Finally, we present guidelines for visualizing blockchain in construction projects, which involve: (1) targeting the visualization domain, (2) planning the blockchain visualization, (3) choosing a visualization tool, (4) selecting a visualization medium, and (5) fine-tuning the visualization solution. This research encourages researchers to further develop visualization solutions to harness blockchain benefits in CEM.

Academic research in applied disciplines such as construction engineering and management (CEM) has the dual mission of simultaneously contributing to the solution of practical problems and creating theoretical and conceptual knowledge. To do so, appropriate research approaches are needed. However, extant literature in the field has paid little attention to this issue and research methods used have been almost entirely either quantitative surveys or case studies. In this paper, action research (AR) is proposed as an answer to this knowledge gap. AR aims at building and testing theory within the context of solving an immediate practical problem in a real setting. The paper describes the underlying philosophy and application procedure of AR and highlights its strengths and weaknesses. Then, the applicability of the method to CEM is illustrated through a case study of improving access to information to support planning and decision making in a construction owner organization through designing and implementing a data warehouse. The findings indicate that AR is a reliable, structured, and rigorous research approach that is very useful for conducting applied research in construction and enabling academia to influence and improve construction industry practices. It can also effectively help to improve collaboration between academic researchers and industry practitioners in research and development projects.

This pedagogical study aimed to demonstrate an updated Building Information Modelling (BIM) educational activity in CEM (i.e., construction engineering and management) students’ final semester project. It investigated students’ perceptions of BIM and the project. Student feedback provided insights for linking education to practice, for example, what caused differences between manual estimates and BIM-generated quantity take-off. Four different project deliverable options demonstrated how educational theories could be embedded in BIM education. The novelty of this study lies in two aspects: firstly, this pedagogical research views the CEM education at the curriculum level by linking earlier years’ core CEM courses into the final project work; secondly, by designing four different options of BIM-related deliverables, subgroup analyses test how different factors, such as teamwork verse individual work, and BIM application level, could affect students’ learning outcomes. The current study also led to more future explorations in research-informed teaching in the CEM curriculum.

This study proposes incorporating generative artificial intelligence large language models (LLMs) into the Master of Science (M.Sc.) curriculum on digitization in construction. The aim was to help students generate computer code to solve, automate, and streamline practical challenges in advanced construction engineering and management (CEM). To this end, a host of problem-based learning (PBL) individual assignments and collaborative team projects were developed, alongside a combination of flipped classroom models and blended learning lessons, in order to teach effective interactions with LLMs and mitigate concerns, such as bias and hallucination. The effective interaction with LLMs not only facilitated code generation, which would otherwise be complex without additional formal training, but also provided a platform for strengthening basic project management skills, such as departmentalization, work breakdown structuring, modularization, activity delegation, and defining key performance indicators. The effectiveness of this approach was quantitatively and qualitatively evaluated within two new modules, Digital Engineering and Construction and Digital Technologies in Field Information Modeling. These modules were offered over three semesters each as part of a new M.Sc. program in Technology and Management in Construction at the Karlsruhe Institute of Technology. It was observed that 86.4% of students fully completed the PBL projects, while the remaining 13.6% achieved over 50% completion across all six semesters. Furthermore, anonymous student surveys indicated a teaching quality index of 100% in five semesters and 96.4% in one semester. These preliminary results suggest that the proposed strategy can be used to effectively integrate LLMs to support students in code generation for open-ended projects in CEM. Further research was, however, found to be necessary to ensure the sustainable revision and redesign of the problems as LLM capabilities evolve.

The University of Washington’s Department of Construction Management is in the process of developing interdisciplinary research and experiential education in construction engineering and management (CEM) with the creation of the 28,000 ft2 Pacific Northwest Center for construction research and education (PNCCRE). In doing so, the department has identified challenges, limitations, and issues centered on bringing industry experience into the classroom and bringing researchers together from diverse disciplines from across the university. The University of Washington envisions the PNCCRE as a place where learners will experience CEM theory and skills firsthand in an interdisciplinary research environment that will foster innovation. This paper focuses on how the Department of Construction Management at the University of Washington is reenvisioning its research and education activities to take advantage of the new PNCCRE facility. In the education front, this paper introduces “the experience learning model,” a...

The rapid growth of construction megaprojects worldwide has triggered a growing number of papers published in this area in the past two decades, suggesting that construction megaproject management has become an emerging area in the field of construction engineering and management (CEM). This study aims to investigate the status and the trends in megaproject research by conducting a structured literature review. A total of 85 relevant articles identified from eight peer-reviewed CEM journals between 2000 and 2010 were analyzed based on the number of articles published annually, institutional and regional contributions, citations, and categorization of research interests and methodologies. Analysis results indicated that developed countries, such as the United Kingdom, the United States, and Australia, have enjoyed significant advantages in megaproject research because of their greater experience, while megaproject research in developing countries, such as Russia, India, Turkey, and Vietnam, remains weak or lacking. These results also revealed that many theory-based findings have been reported in five subareas; namely, construction and site management, cost and schedule management, risk analysis and management, innovation and utilization of information technology, and leadership and professional development. The subareas of organization and stakeholder management, project planning and procurement, and project monitoring and control remain to be promising domains for future research, particularly in developing countries which have yet to develop a research tradition. Incorporating the complexity theory and institutional theory as the theoretical foundation in these subareas can develop megaproject research further through strengthened global collaboration in the future.

Gathering knowledge from expert practitioners is a hallmark of construction engineering and management research. However, the knowledge gathered is dependent on the knowledge of the people we talk to. Accordingly, this paper used a content analysis of 12 months of recent technical articles and case study publications in the Journal of Construction Engineering and Management to explore characteristics of research respondents that authors publishing in this journal feel are important to document. Authors report some subset of research respondents' job type or role, years of experience, subject matter expertise, geography or nationality, organization and sector details, project type, professional qualifications, sex, race and ethnicity, ability, and language. Accordingly, this paper recommends that researchers should report at least these categories, and that researchers also should discuss research limitations that may result from the types of people they collect knowledge from. This change will make visible voices that are dominant or underrepresented in construction engineering and management research. In addition, by eliminating an otherwise unstated limitation, this change will result in improved construction engineering and management science.

Purpose The purpose of this paper is to highlight the value of interdisciplinary learning specifically in the architecture (ARCH), building construction (BC) and construction management and engineering (CEM) disciplines within the USA’s higher education system. The study attempts to expand the existing literature on integrated design and construction education and offer an alternative model for academic students’ collaboration when restructuring curriculums is not possible in the short term. Design/methodology/approach The study adopted a qualitative research methodology, which involved designing a structured learning experiment, then followed it with collecting the “lived experience” of 31 participants from three majors according to the institution’s institution review board (IRB) office’s guidelines. The author hypothesized that students from different, but related disciplines working on a real-life project, would better understand the value of each other’s knowledge brought to the teamwork before graduation. The data were analyzed and compared to existing literature on integrated project delivery, and collaborative learning models. Data collection (surveys) was approved by the higher education’s IRB No. 13-021. Findings Despite the already-existing curriculum obstacles, the majority of students were very pleased with this collaborative experiment. The results confirmed many of the expectations about how students viewed each other’s discipline. The preconceived notions were dissipated at the end of the study, and students expressed more appreciation for each other’s field and expressed interest in learning more about the thought processes of other disciplines. Research limitations/implications Typical conflicting academic schedules were the greatest obstacle in this experiment. Architecture students often devote majority of their time to design studios and therefore are unable to fully engage in an integrated capstone project like this one as extracurricular. Because of the chosen research approach, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed propositions further. Practical implications It is possible to develop a successful collaborative experience in the architecture, engineering and construction higher education system without major restructuring of the curriculums. The impact on students’ learning experience is greater than the existing separated education model. Originality/value This paper fulfills an identified need to study how integrated design and construction education occurs without creating new dedicated programs or coursework.

Moreover, there is an increasing amount of literature covering specific geotechnical risk analysis and management topics. Examples of these are the difference between unsafe geotechnical certainty and safe geotechnical uncertainty (Barends, 2005), the role of the human factor in achieving geotechnical reliability (Bea, 2006), objective and subjective ways of geotechnical risk classification (Altabba et al., 2004), and contractual allocation of geotechnical risk (Essex, 2007).

ABSTRACTMultirotor drones are considered a new and innovative technology. Therefore, many fields are showing increasing interest in utilizing multirotor drones, such as mapping in mining and surveillance in transportation. The construction industry has been a slow adopter of novel technologies. However, multirotor drones have potential to facilitate construction in many aspects. There is, therefore, a need to extensively research their applications and analyze their roles in construction engineering and management. This paper aims to comprehensively investigate the current applications of multirotor drones, analyze their benefits and explore their potential in the future of the construction industry. Several main aspects are reviewed and discussed, namely land surveying, logistics, on-site construction, maintenance and demolition. The results reveal that the main contributions are work safety, cost-effectiveness and carbon emission reduction, while there are possible adverse impacts on the basis of current limitations of multirotor drones. However, it can be predicted that the usefulness of drones will continue to increase in the future of the construction industry. Thus, this study will benefit construction managers in raising awareness of the use of these emerging technologies and researchers in further exploring applications of multirotor drones in construction projects.

Ethical decision-making is central to the practice of construction engineering and management. This is no more evident than in the twenty-first century, when the construction industry must function in very diverse organizational contexts. Whilst construction companies pursue projects in international markets, many investors are buying or forming joint ventures with domestic companies. New and varied professional attitudes have recently arrived in western markets such as the United States and Australia because construction companies are increasingly employing managers from developing nations to undertake commercial and infrastructure engineering projects. In many developing countries the construction industry is vulnerable to unethical behavior or corruption – vulnerability in part because of differences in culture and managerial systems across countries; and this diversity is manifest in the different perspectives of professional ethics and professional practice. Importantly, professionals in construction engineering must be aware of these differences; however current ethics education for engineering professionals generally lacks global components. In this chapter, emphasis is placed upon professional registration, including mandatory awareness of professional ethics, as an imperative for the welfare of world citizens; discussion on the nature of the construction industry and globalized trends emphasizes why ethics and professional education must be integrated within civil and construction engineering and management curricula. Only then we can anticipate an appropriate educational foundation for professional registration of the international engineer.

Risk management is one of the topical areas in construction project management research. However, no attempt has been made in the past decades to explore the emerging themes in this area. This paper reviews the research trends in risk management in construction. The bibliometric data of 1635 publications between 1979 and 2022 were extracted from Scopus using a set of keywords. The study used VOSviewer and Gephi to conduct a scientometric analysis on the extracted publications. The review outcome indicates a significant increase in publications on risk management in construction, with about 205 publications recorded between 2021 and 2022 alone. Based on this analysis, it is projected that the next decade will see significant research on risk management, especially as the construction industry moves towards Industry 5.0 with many uncertainties. Further, the most productive countries of risk management studies in construction include China, the United States, the United Kingdom, Australia, and Hong Kong. Emerging key research areas are discussed using network diagrams and clusters. These areas include the processes in risk management, risk analytical models and techniques, sources of risk and uncertainties, effective knowledge-based systems for improved risk management, risk contingency in construction contracts, risk-integrated project planning and scheduling, and stakeholder management. The findings of this study inform researchers on the current progress of risk management studies in construction and highlight possible research directions that can be considered.
