Purpose The purpose of this study is to discover the distribution and trends of existing Offsite construction (OSC) literature with an intention to highlight research niches and propose the future outline. Design/methodology/approach The paper adopted literature reviews methodology involving 1,057 relevant documents published in 2008-2017 from 15 journals. The selected documents were empirically analyzed through a topic-modeling technique. A latent Dirichlet allocation model was applied to each document to infer 50 key topics. A machine learning for language toolkit was used to get topic posterior word distribution and word composition. Findings This is an exploratory study, which identifies the distribution of topics and themes; the trend of topics and themes; journal distribution trends; and comparative topic, themes and journal distribution trend. The distribution and trends show an increase in researcher’s interest and the journal’s priority on OSC research. Nevertheless, OSC existing literature is faced with; under-researched topics such as building information modeling, smart construction and marketing. The under-researched themes include organizational management, supply chain and context. The authors also found an overload of similar information in prefabrication and concrete topics. Furthermore, the innovative methods and constraints themes were found to be overloaded with similar information. Research limitations/implications The naming of the themes was based on our own interpretation; hence, the research results may lack generalizability. Therefore, a comparative study using different data processing is proposed. The study also provides future research outline as follows: studying OSC topics from dynamic evolution perspective and identifying the new emerging topics; searching for effective strategies to enhance OSC research; identifying the contribution of countries, affiliation and funding agency; and studying the impact of these themes to the adoption of OSC. Practical implications This study is of values to the scholars, as it could stimulate research to under-researched areas. Originality/value This paper justifies a need to have a broad understanding of the nature and structure of existing OSC literature.

Purpose Current facility management (FM) practices are inefficient and ineffective, partially because of missing information and communication issues. Information and communications technologies (ICT) are asserted to provide a promising solution for managing and operating facilities. However, the impact of ICT applications on current FM practices needs to be validated and the perception of FM professionals on ICT-based FM needs to be understood. Therefore, this paper aims to investigate the impacts and the perception of ICT application on FM practice and further develop an ICT-based integrated framework for smart FM practices. Design/methodology/approach To achieve the objective, the research starts with reviewing several promising ICT for FM, including building information modeling, geographic information systems, unmanned aerial vehicle and augmented reality. On this basis, a conceptional framework was synthesized in consideration of the benefits of each technology. A survey questionnaire to FM professionals was conducted to evaluate the proposed framework and identify the challenges of adopting ICT in the FM industry. Furthermore, return on investment and strength, weakness, opportunities and threats analysis have been used in this paper as evaluation methods for ICT industry adoption. Findings The survey results are validated by FM professionals for the future engagement of the integrated ICT applications. Also, the proposed framework can assist the decision-makers to have comprehensive information about facilities and systematize the communication among stakeholders. Originality/value This research provides an integrated framework for smart FM to improve decision-making, capitalizing on the ICT applications. Apart from this, the study sheds light on future research endeavors for other ICT applications.

The Impact

Purpose Building information modelling (BIM) creates a golden thread of information of the facility, which proves useful to those with the malicious intent of breaching the security of the facility. A cyber-attack incurs adverse implications for the facility and its managing organisation. Hence, this paper aims to unravel the impact of a cybersecurity breach, by developing a BIM-facilities management (FM) cybersecurity-risk-matrix to portray what a cybersecurity attack means for various working areas of FM. Design/methodology/approach This study commenced with exploring cybersecurity within various stages of a BIM project. This showcased a heightened risk of cybersecurity at the post-occupancy phase. Hence, thematic analysis of two main domains of BIM-FM and cybersecurity in the built environment led to the development of a matrix that illustrated the impact of a cybersecurity attack on a BIM-FM organisation. Findings Findings show that the existing approaches to the management of cybersecurity in BIM-FM are technology-dependent, resulting in an over-reliance on technology and a lack of cybersecurity awareness of aspects related to people and processes. This study sheds light on the criticality of cyber-risk at the post-occupancy phase, highlighting the FM areas which will be compromised as a result of a cyber-attack. Originality/value This study seeks to shift focus to the people and process aspects of cybersecurity in BIM-FM. Through discussing the interconnections between the physical and digital assets of a built facility, this study develops a cyber-risk matrix, which acts as a foundation for empirical investigations of the matter in future research.

Acceptance Model

Purpose Although the notable and significant role of building information modeling (BIM) technologies in construction industries has gained user attention, only few studies have been examined on the user adoption of the technologies. The purpose of this paper is to introduce an acceptance model for BIM technologies and investigate how external factors which were extracted by in-depth interviews promote the adoption of such technologies. Design/methodology/approach An on-line survey was conducted by two South Korean survey agencies to test the acceptance model for BIM technologies. Then, the structural equation modeling (SEM) and confirmatory factor analysis (CFA) methods were used. Findings The results of the SEM and CFA methods from on-site construction employees (n=818) in Korea collected by the online survey indicate that compatibility and organizational support play a core role in positively and significantly affecting both perceived ease of use and usefulness, and that the connections introduced by the origin technology acceptance model are mainly confirmed. Originality/value Using the findings of the results, both implications and notable limitations are presented. Moreover, practical developers, as well as academic researchers can employ the results when they attempt to conduct future research.

Purpose Prompt and effective responses to incompatibilities between as-designed and as-built drawings prevent cost and time overruns and material waste. This paper aims to provide an efficient framework to handle mismatches between these two models with the least negative impact on the whole project. Design/methodology/approach First, 11 most frequent mismatches were identified through questionnaires. Also, the respondents were asked to determine the mismatches’ roots and solutions and the impact of applying solutions on the whole project. Afterward, the process to present the optimum solution to one of these mismatches was modeled. After running the application programming interface developed in Navisworks software, decision-makers access a form, showing mismatches, their causes and solutions, as well as the solutions’ effect. To finalize the optimal solution, a platform was provided on whether to accept the system solution or to propose an alternative. Findings To empirically validate the reliability of the proposed framework, two projects were investigated. Two different approaches to dealing with the same mismatch occurred in these projects were compared in terms of time, cost and material required. The results showed that addressing the mismatches through the proposed framework can efficiently enhance time, cost and material consumption, in comparison with the traditional approach. Originality/value There is currently no building information modeling-based holistic framework for managing mismatches between as-designed and as-built drawings. The results of this research can help contractors to make the best decision, saving project resources, when setting about a mismatch during construction.

Considerable Work

PurposeDespite the continuous development of Building Information Modeling (BIM) standards, not all of its dimensions are supported to the same extent. This is the case of Building Automation Systems (BAS) in which the features that are limited mostly to physical setup of devices are supported. These are largely insufficient to support modeling automation scenarios. The purpose of this article is to clarify the gap in the state of the art and define the need for further developments.Design/methodology/approachThis article explores the existing gap in the literature and discusses the hypothesis of extending BIM to a wider support of BA concepts. Based on an assessment of scientific and technical literature, this study elicits the information requirements of BA and performs a gap analysis with current BIM standards, such as Industry Foundation Classes (IFC).FindingsOur findings lead us to conclude that there is a lack of completeness regarding features from BAS automation and management levels. Furthermore, it is shown that IFC is the most adequate data model to cover BAS without losing its purpose, but there is still a considerable work that needs to be addressed in future research.Originality/valueBIM standards such as IFC position themselves as natural candidates for modeling and exchanging information regarding BA. However, the extent to which BIM supports automation features has never been rigorously analyzed. This article explores the existing gap in the literature and discusses the hypothesis of extending BIM to a wider support of BA concepts. Based on an assessment of scientific and technical literature, this study elicits the information requirements of BA and performs a gap analysis with current BIM standards such as IFC.

Purpose As the use of building information modeling (BIM) for facilities management (FM) continues to grow, questions remain around the quality and completeness of digital assets to support FM practices. This paper aims to examine the current gap between digital and physical assets in the absence of formal information requirements and its impact on the handover process. Design/methodology/approach An action-research was carried out with a large public organization to understand the challenges of their current FM processes and the steps required in developing an asset information model (AIM) from a project information model (PIM). A mixed method approach was employed with interviews, document analysis and an exploratory pilot case study. Findings This paper investigates the process, the challenges and the level of effort of the information commissioning process to create a fit-for-use AIM. Four distinct steps were identified in the process as follows: analyzing the handover PIM and documents, extracting FM-specific information, populating the model with the information and attaching operations and maintenance (O&M) documents. The research highlights the significant amount of effort that is required when no specific asset information requirements are formulated at the project onset. Practical implications The paper presents an information commissioning process that helps to develop an AIM from a PIM. Understanding the impact of the lack of requirements on the information commissioning process can help asset owners understand the importance of defining and articulating their information requirements up front. Originality/value This paper provides empirical evidence of the impact of the absence of formal information requirements on the development of a fit-for-use AIM.

Purpose This paper aims to present a review of research developments relating to the application of building information modeling (BIM) to facilities management (FM). It sheds light on major technical and organizational issues with the view of identifying how existing BIM for FM knowledge applies to large capital projects. Design/methodology/approach The study adopted a literature search approach to retrieve relevant articles which were subjected to keyword analysis to enable categorization of extant BIM for FM research into appropriate sub-domains. A qualitative analysis of 94 BIM for FM-related literature was carried out in addition to a review of 9 capital project-related articles, leading to the establishment of research trends, gaps and future directions. Findings The review found that research in the BIM-FM integration field is predominantly technology and process-oriented, with less attention paid to people or organizational aspects. Therefore, there is a need for expanding the knowledge base in this direction. Several future research directions were identified to lay the foundations for research on BIM application to FM in large capital projects and other application areas for interested researchers. These future directions were categorized under the identified sub-domains of the field and mapped onto two generic activities, i.e. technical integration and business integration, involved in technology adoption by organizations. Originality/value The main contribution of this study is the categorization of existing research on BIM for FM, leading to the identification of research gaps concerning the initiation and implementation of BIM for FM in large capital projects. As a secondary benefit, this study has validated some sub-domains of the BIM for the FM research field identified in previous review papers using an empirical approach. This validation of defined sub-domains is useful for an emerging research field as it provides a common understanding of trends and specific application areas.

Public Health Emergencies

Purpose The purpose of this paper is to identify salient topic categories and outline their evolution patterns and temporal trends in microblogs on a public health emergency across different stages. Comparisons were also examined to reveal the similarities and differences between those patterns and trends on microblog platforms of different languages and from different nations. Design/methodology/approach A total of 459,266 microblog entries about the Ebola outbreak in West Africa in 2014 on Twitter and Weibo were collected for nine months after the inception of the outbreak. Topics were detected by the latent Dirichlet allocation model and classified into several categories. The daily tweets were analyzed with the self-organizing map technique and labeled with the most salient topics. The investigated time span was divided into three stages, and the most salient topic categories were identified for each stage. Findings In total, 14 salient topic categories were identified in microblogs about the Ebola outbreak and were summarized as increasing, decreasing, fluctuating or ephemeral types. The topical evolution patterns of microblogs and temporal trends for topic categories vary on different microblog platforms. Twitter users were keen on the dynamics of the Ebola outbreak, such as status description, secondary events and so forth, while Weibo users focused on background knowledge of Ebola and precautions. Originality/value This study revealed evolution patterns and temporal trends of microblog topics on a public health emergency. The findings can help administrators of public health emergencies and microblog communities work together to better satisfy information needs and physical demands by the public when public health emergencies are in progress.
