The purpose of this study is to investigate the mutual interactions between the causes of design changes using Interpretive Structural Modeling (ISM) and to classify the causes using the “Matrice d’Impacts Croisés Multiplication Appliquée à un Classement” MICMAC technique. This study further identifies and proposes strategies to mitigate design change occurrence and map them onto the identified connections between the causes. To achieve these goals, critical causes of design changes were identified through a comprehensive literature review; 23 key causes were then refined according to the opinions of relevant experts involved in the Iranian building construction sector. Stakeholders associated with each cause and the management areas from which causes arise were also considered. The factors “Unfamiliarity with new construction methods”, “Design errors”, “Value engineering”, “Scope uncertainty”, “Change orders”, and “Constructability ignored in the design phase”, which are highly influenced by other factors, emerged at the highest level of the ISM diagram, and “Clients’ attitudes and experience” as the main root cause of design changes at the bottom of the diagram. The MICMAC technique results showed that consultant-related causes significantly influence other causes, and policy and client-related causes have a feedback effect on the whole system. The findings of this study provide a better insight into how various causes of design changes are connected to one another and can ultimately assist project managers of different parties, even in other countries, to choose influential strategies to mitigate design changes in building construction projects.

Since the Belt and Road Initiative (BRI) has been put in practice by the Chinese government, several High-Speed Railways (HSR) have been built by Chinese Engineering Procurement and Construction (EPC) firms. However, many delays have created severe detrimental consequences on the progress of most HSR projects. This study sought to explore the essence of the recurring triggers of delays in international EPC HSR projects under the BRI, and a structured questionnaire survey approach was applied to compile the first-hand dataset from Chinese EPC firms working for BRI infrastructure projects. The data were evaluated, and the Relative Importance Index (RII) was adopted to assess the magnitude of the important delay triggers. The findings suggest that HSR projects are still susceptible to unavoidable delays in global construction infrastructure projects. In the engineering phase, improper management of the design, unsustainable land acquisition, and insufficient use of EPC joint venture are the salient trigger of delays. In the procurement phase, the leading causes of unsuitable procurement, undervalued procurement cost, inefficient logistics in labor and materials, improper planning, unqualified site supervisors, inefficient technical standard management, and inefficient constant payment terms are likely to trigger delays in the construction phase HSR projects. Five critical groups of delay factors are identified by this study, which has an essential primary contribution to the body of knowledge and is helpful to EPC contractors working for HSR projects under BRI.

Agribusiness supply chain (ASC) risk is currently a major business problem throughout the world. The current trend of globalisation has affected every business, and supply chain risks have become a concern in logistics and other business processes. Current risk management strategies must address a variety of global and local challenges. To tackle this issue, existing research has analysed risks in agrifood supply chains, ASC risk management, disruption in ASCs, risk assessments of agriculture supply chains and sources of risk facing an agricultural supply chain. However, the existing research has not defined and categorised risks as a basis for managing risks in ASCs. Therefore, the definition and categorisation of risks in the ASC has been overlooked. To address this gap, this paper undertakes a systematic literature review, offering constructs to define and categorise risks in ASCs, and develops a novel taxonomy in ASC risks to enrich future research on ASC risk management. Sixty-one articles from six databases published between 2000 and 2020 underwent descriptive and thematic analysis.

Construction sites constitute major sources of pollutants creating negative impacts on the environment. Sustainable construction aims at mitigating these negative externalities while promoting economic and social outcomes. Dust pollution in construction sites is an invisible hazard, which is often ignored as little more than a nuisance. Although behavioral control is a popular way of preventing dust generation, past research has paid little attention to worker behavior regarding dust mitigation. This study aims to test a model that predicts intentions to alter the conduct of workers towards dust control in construction activities. This study adopted a questionnaire survey design with construction participants in Sri Lanka, using structural equation modelling to test several hypotheses based on the Norm Activation Model. The results proved that awareness of consequences and ascription of responsibility could have a positive impact on personal norms, which in turn could influence the behavior of site employees. The study also provided new insights on employees’ awareness of dust hazards, their sense of responsibility for its control, and the importance of their company. Policymakers and practitioners are recommended to pay more attention to how to harness worker’s support to mitigate dust pollution, and construction companies should initiate educational campaigns to raise awareness about environmental impacts, to influence personal norms of the workers in building sites. This research contributes to the body of knowledge by enhancing our understanding of factors influencing employees’ dust control behavior.

This research aims to develop a safety culture model by investigating the relationship between safety culture and driving performance. In previous studies, safety culture has been one of the factors that determine safety issues. These issues were then contextually transformed via a pilot study and organized in the form of a theoretical model. The data were collected from 307 oil and gas tanker drivers in Malaysia through questionnaire surveys. Consequently, structural equation models of partial least squares (PLS-SEM) were applied to statistically assess the final model of this study. The results showed that the implementation of safety culture contributes to driving performance at a substantial level; there is a strong association with an effect of 67.3%. The findings of this research would serve as a benchmark for decision-makers in the oil and gas transportation sector, as promoting an awareness of safety culture should boost the efficiency of drivers. This research fills a gap in knowledge by identifying that positive safety culture practices and mindset are direct antecedents for the improvement of driver performance and, thus, the avoidance of road accidents.

The Architecture, Engineering, Construction and Operations (AECO) industry is generally slow in adopting emerging technologies, and such hesitance invariably restricts performance improvements. A plethora of studies have focused on the barriers, Critical Success Factors (CSFs), lifecycle and drivers independently, but none have explored the impact of BIM drivers and awareness on the project lifecycle. This study empirically explored the impact of BIM drivers and awareness on the project lifecycle using Structural Equation Modelling (SEM). Initially, a conceptual model was developed from an extensive literature review. Thereafter, the model was tested using primary questionnaire data obtained from 90 construction professionals in Lagos, Nigeria. Emergent findings indicate that Building Information Modelling (BIM) drivers have a high impact on BIM awareness at the operation stage of the project lifecycle. The SEM model has an average R2 value of 23% which is moderate. Consequently, this research contributes to the existing body of knowledge by providing invaluable insight into the impact of BIM drivers on BIM awareness in the project lifecycle. Knowledge acquired will help industry stakeholders and government to develop appropriate policies to increase BIM uptake within contemporary practice.

Historically, fire incidents in high-rise buildings reveal that Fire and Rescue Services frequently rely on the stay-put tactic (i.e., occupants of high-rise buildings should remain in their apartments) during an inferno. Recent fire occurrences in high-rise buildings reveal that there are two opposing viewpoints on the stay-put tactic. First, the understanding that the stay-put tactic is a beneficial practice used to protect, control, and facilitate smooth evacuation of occupants during fire incidents. Second, the argument that the stay-put tactic is a misjudgement and futile strategy that leads to fatalities, particularly in high-rise buildings. The aim of this study was to provide awareness and understanding of fire and rescue services use of the stay-put tactic in high-rise buildings. We attempted to answer the questions: is the stay-put tactic a misjudgement or magnificent strategy? The study adopted phenomenological research strategies with various focus groups consisting of seasoned firefighters and survivors with first-hand accounts of stay-put instructions in high-rise buildings. The study also scrutinised three case studies of fire incidents in high-rise buildings in two countries. The study revealed that the stay-put tactic is obsolete; with the potential to cause catastrophic misjudgement, mostly during conflagrations in high-rise buildings. There is a need to advance research on the use of artificial intelligence communication systems and infrared image detectors camera to enhance quick and smooth fire evacuation in high-rise buildings.

Making project management practices sustainable is an essential component to the broader mission of making the construction industry, as a whole, truly sustainable. In pursuit of this objective, numerous studies have collectively identified a plethora of barriers inhibiting construction project management sustainable transition. While such knowledge is instructive, it presents its own barrier as prevailing challenges cannot be tackled simultaneously and redressing barriers individually (and in isolation) has proven ineffective. This research therefore seeks to examine the interrelationship and dependency of these barriers, doing so in the context of the Iranian construction industry, and by using statistical means to identify underlying meta-barrier factors. Extracted from the extant literature, thirty initial barriers are defined and delineated to inform a survey data collection instrument delivered to Iranian industry experts. Of 454 questionnaires distributed to construction professionals, 176 valid responses were returned and Social Network Analysis (SNA) tools were adopted to analyse the data. Five core thematic clusters of barriers were observed to impede the industry's project management sustainability transition, namely: 1) project context; 2) knowledge; 3) investment; 4) community; and 5) strategy. Based upon these five meta clusters of barriers, future industry and government policies could set frameworks for moving towards sustainability and identify the root causes of the failure in their projects' sustainable practices. The research concludes by delineating future direction for further research investigation. This study contributes to the field through analysing the linkages between barriers and distils them into five broad problem sets. This method provides a more manageable approach and offers industry practitioners in Iran holistic insight on how to effect positive change towards sustainable project management practices, and in turn, a sustainable construction industry. In so doing, the study provides lessons for other developing countries.

This article provides a picture of the latest developments in providing BIM-based tools for construction and demolition waste (CDW) management. The coverage and breadth of the literature on offering BIM-based tools and technologies for dealing with CDW throughout the whole life cycle of construction are investigated, and gaps are identified. Findings reveal that, although various BIM-based technologies are closely associated with CDW, much of the existing research on this area has focused on the design and construction phase; indeed, the problem of CDW in post-construction stages has received scant attention. Besides, the now available tools and technologies are lacking in cross-phase insights into project waste aspects and are weak in theoretical rigor. This article contributes to the field by identifying the intellectual deficiencies in offering BIM-based tools and technologies when dealing with CDW. So, too, it points to major priorities for future research on the topic. For practitioners, the study provides a point of reference and raises awareness in the field about the most advanced available BIM-based technologies for dealing with CDW problems.

Risk handling is one of the elements and essential parts of risk management when properly incorporated into a project. However, there is inadequate knowledge amongst the contractual parties on risk handling responsibilities in road projects, particularly in Sub-Saharan African developing countries. This study is aimed at bridging that knowledge gap by investigating the perceptions of contractors and consultants on the risk handling responsibilities in road projects in Tanzania. The primary data were collected from 80 registered foreign and local civil contractors and engineering consultants based in Dar es Salaam. Descriptive statistics and inferential statistics were used for the data analysis. The results show that both contractors and consultants ranked safety project provision and ensuring quality provision in terms of construction as shared risk responsibilities among contractual parties. The findings further show that consultant-related risk responsibilities are: safety provision, the use of historical cost deviation, ensuring quality provision, and review of knowledge on budgeting. On the other hand, contractor-related risk responsibilities include: safety provision and ensuring quality provision. The findings of this study can be used by the practitioners and stakeholders as important lessons useful for controlling risks and making decisions when they intend to participate in such projects during the construction stage.

Purpose The purpose of this paper is to assess the influence of value management (VM) critical success factors (CSFs) on the implementation of VM activities in building projects with a view to promoting sustainability of construction industry in Egypt. Design/methodology/approach The VM CSFs and implementation activities were recognized from earlier studies; questionnaire survey was conducted to collect data from relevant stakeholders, and the collected data was subjected to exploratory factor analysis. Consequently, the influence of VM CSFs on VM implementation was generated via partial least square structural equation modelling. In addition, through relative importance ranking analysis, the significance VM CSFs were examined. Findings The findings from the proposed model revealed a strong relationship between VM implementation activities and its CSFs; the relationship is at a moderate level with an effect of 22.0%. This indicates that, VM CSFs would be useful to implement VM in the Egyptian building industry. Research limitations/implications Although these studies have been confined to Egypt’s VM studies; they may apply to other developing countries that have not carried out these studies. It is therefore vital, in those countries where the exercise has been entirely undertaken, to analyze the various measures to promote the application of the method. Practical implications This research would be of benefit to stakeholders in building industries to be aware of VM phases and its CSFs that demand utmost consideration. Also, the identified CSFs are expected to enhance the success and value of building projects by adopting VM. Originality/value The novelty of this research work will be a benchmark or board for decision-makers to eliminate the unwanted cost and enhance quality by adopting VM in Egypt’s building projects to achieve their sustainable projects.

While the performance of sports facilities such as swimming pools is crucial to the health, safety and enjoyment of pool users, little research has been conducted to explore how to analytically evaluate the holistic performance of such facilities from the users' perspective. Even an evaluation framework portraying the key performance attributes of swimming pools is yet to be available. Recognising this research gap, this study aims to adopt a user-centric approach to evaluate the performance of swimming pools and a multi-stage study was initiated. After a thorough literature review, a performance attribute hierarchy for swimming pools was established through a focus group study and then two surveys, covering four swimming pools and 103 pool users interviewed, were conducted in Hong Kong. Analysing the responses using the Analytic Hierarchy Process (AHP) method illustrates that the building services (i.e. utilitarian) aspect of swimming pools is more important than the architectural counterpart, and survey participants cared more about the performance attributes inside water than those outside. This study's novelty lies in that it adopted the user-centric approach, which can differentiate between the relative importance of different swimming pool components and prioritize resources for their maintenance and management. The evaluation framework as well as the findings of the study provides facilities managers with important benchmark criteria for optimising the performance of these sports facilities. In the long run, this study contributes to enabling the project stakeholders to conduct evidence-based decision making over the life cycle of sport facilities development and management.

Using a systematic review of literature, this study identifies the potential impact of blockchain solutions for augmenting supply chain resilience (SCR) to cybercrime. This rich literature synthesis forms the basis of a novel theoretical framework that provides guidance and insight for blockchain adopters and vendors as well as delineate palpable benefits of this novel technology. An interpretivist philosophical design and inductive reasoning are adopted to conduct the systematic review of literature. A total of 867 papers were retrieved from Scopus database between the years of 2016 and 2020 and subsequently analysed via abductive reasoning, grounded theory and a thematic meta-analysis; where the latter was achieved using a scientometric approach and software tools such as VOS viewer and NVivo. Scientometric analysis revealed the most prolific countries, sources, publications and authors who reside at the vanguard of blockchain developments and adoption. Subsequent grounded theory analysis identified six main clusters of research endeavour viz: “case study”, “challenges and opportunity”, “traceability”, “smart contract” “blockchain and IoT” and “data security”. From 28 SCR metrics identified within literature, five were found to have been positively impacted by blockchain technology solutions, namely: “visibility”, “collaboration”, “integration”, “risk management” and “information sharing.” Prominent applications of blockchain technology in practice were “traceability systems” and “smart contracts” which are often implemented separately or in combination and primarily in food supply chains. This research constitutes the first study to critically synthesise extant literature for evaluation of blockchain solutions’ implication on SCR metrics. New perspectives obtained provided a basis for the novel theoretical framework for implementation that will be valued by software developers and adopting organizations, whilst creating new direction for researchers interested in blockchain technology.

Physical contact and respiratory droplet transmission have been widely regarded as the main routes of COVID-19 infection. However, mounting evidence has unveiled the risk of aerosol transmission of the virus. Whereas caution has been taken to avoid this risk in association with clinical facilities, facilities such as spa pools and Jacuzzis, which are characterized by bubble-aerosol generation, high bather loads, and limited turnover rates, may promote aerosol transmission. Focusing on these non-clinical facilities in the built environment, a review study was undertaken. First, the typical water disinfection and ventilation-aided operations for the facilities were illustrated. Second, cross comparisons were made between the applicable standards and guidelines of the World Health Organization and countries including Australia, Canada, China, the United Kingdom, and the United States. The similarities and differences in their water quality specifications, ventilation requirements, and air quality enhancement measures were identified; there were no specific regulations for preventing aerosol transmission at those aerosol-generating facilities. Third, a qualitative review of research publications revealed the emergence of studies on potential air-borne transmission of COVID-19, but research on built facilities posing high risks of aerosol transmission remains scant. This study’s results inform key directions for future research on abating aerosol transmission of COVID-19: the development of bespoke personal protective equipment and engineering and management controls on water quality, ventilation, and air quality.

Driving fatigue is a serious issue for the transportation sector, decreasing the driver’s performance and increasing accident risk. This study aims to investigate how fatigue mediates the relationship between the nature of work factors and driving performance. The approach included a review of the previous studies to select the dimensional items for the data collection instrument. A pilot test to identify potential modification to the questionnaire was conducted, then structural equation modelling (SEM) was performed on a stratified sample of 307 drivers, to test the suggested hypotheses. Based on the results, five hypotheses have indirect relationships, four of which have a significant effect. Besides, the results show that driving fatigue partially mediates the relationship between the work schedule and driving performance and fully mediates in the relationship between work activities and driving performance. The nature of work and human factors is the most common reason related to road accidents. Therefore, the emphasis on driving performance and fatigue factors would thereby lead to preventing fatal crashes and life loss.

This research explores the failure of competitively tendered projects in the UK construction industry to procure the most suited contractor(s) to conduct the works. Such work may have equal relevance for other developed nations globally. This research seeks to teach clients and their representatives that “lowest price” does not mean “best value”, by presenting a case study of a successfully negotiated tender undertaken by a small-to-medium enterprise (SME) contractor; SME studies are relatively scant in academic literature. By applying the “lessons learnt” principle, this study seeks to improve future practice through the development of a novel alternative procurement option (i.e., negotiation). A mixed philosophical stance combining interpretivism and pragmatism was used—interpretivism to critically review literature in order to form the basis of inductive research to discuss negotiation as a viable procurement route, and pragmatism to analyse perceptions of tendering and procurement. The methods used follow a three-stage waterfall process including: (1) literature review and pilot study; (2) quantitative analysis of case study data; and (3) qualitative data collection via a focus group. Our research underscores the need to advise clients and their representatives of the importance of understanding the scope of works allowed within a tender submission before discounting it based solely on price. In addition, we highlight the failings of competitive tendering, which results in increased costs and project duration once the works commence on site. These findings provide new contemporary insight into procurement and tendering in the construction industry, with emphasis on SME contractors, existing relationships, and open-book negotiation. This research illustrates the adverse effects of early cost estimates produced without first securing a true understanding of project buildability and programming. Our work concludes with a novel insight into an alternative procurement option that involves early SME contractor involvement in an open-book environment, without the need for a third-party cost control.

Purpose A mixed philosophies epistemological design with inductive reasoning was adopted to develop new theoretical insights into the phenomena under investigation. First, interpretivism was employed to contextualise the prevailing body of knowledge and source questions (and prompts) to be posed to practitioners. Second, a case study strategy (augmented by participant action research) was adopted to measure construction industry professionals' perceptions of the clerk of work's role and their impact upon both quality and safety of construction. Design/methodology/approach This research conducts a case study investigation of affordable and/or social home construction and examine industry's perception of the clerk of works (CoW) and their powers and responsibilities within existing legislation to impact quality of construction. Findings The findings illustrate that while the clerk of work's role positively impacts quality and safety of construction, it is hindered by cost and time constraints that are often prioritised. An analogy to “yield points” in materials science is then adapted to develop new theory to conceptualise the pivotal position that the CoW has in upholding quality construction. The research concludes with pragmatic recommendations (such as industry centric codes of practice) to mitigate quality and safety issues arising and signpost future academic research in this area. Originality/value UK construction has been criticised for prioritising costs and profits vis-à-vis quality and safety issues, as exemplified by the Grenfell fire. This study demonstrates the need for reinstatement of the CoW role in mitigating residential housing quality decline.

Construction industry has adopted reverse logistics (RL) concept to manage high volumes of demolition waste (DW). However, DW RL supply chains (RLSCs) were found to be suffering from uncertainties, information deficiencies, and uncoordinated material flows. Improving supply chain integration (SCI), specifically external integration, across DW RLSCs was identified as a possible solution to overcome such problems. Despite this, studies that focus on external integration in DW RLSCs are limited. Using a systematic literature review (SLR), this study explores external integration in DW RLSCs. Sixty-six articles from three databases published between 2006 and 2020 were subjected to descriptive and content analysis. Arrangement of material, information, and financial flows across DW RLSCs, inhibitors of external integration, and potential measures for improving external integration were analyzed. Accordingly, material, information, and financial flows across DW RLSCs were mapped, and inhibitors of external integration, along with potential measures for improving external integration were identified. As the key outcome of this SLR, these findings were developed into a conceptual framework, which shows the main factors that inhibit and improve external integration in DW RLSCs. The framework will be useful in guiding further empirical research and informing industry practice. Several future research directions are also proposed to expand knowledge around the research domain.

Purpose A scientometric review of extant literature is conducted to define and delineate upon the enabling dynamic capabilities required to engender the digitalisation of organisations operating in the architecture, engineering, construction and operations (AECO) sector. A secondary aim sought to provide direction for future studies and theories to be tested in this novel field of investigation as well as stimulate wider polemic debate amongst industry stakeholders. Design/methodology/approach An interpretivist philosophical stance and inductive approach was undertaken in this study, using a grounded theory strategy. Secondary data used was sourced from the Scopus journal database using specific related keywords. VOSviewer was used to prepare co-occurrence maps based on the bibliographic data gathered. Findings AECO organisations that seek digitalisation must possess the capability to sense and seize opportunities and threats within the business environment and reconfigure their business processes to best meet their market demand. This can be achieved by improving on attributes relating to industrial management and strategic planning, organisational learning, enterprise resource management and innovative information technology. Future studies should target novel areas such as AECO organisations' ambidexterity and service innovation. Originality/value This is the first study to explore the dynamic capabilities of AECO organisations in relation to digitalisation adoption. Therefore, the research serves as a robust theoretical background for signposting AECO organisations who seek to transition to digital solutions in the fourth industrial revolution.

Purpose This paper aims to examine the current technology acceptance model (TAM) in the field of mixed reality and digital twin (MRDT) and identify key factors affecting users' intentions to use MRDT. The factors are used as a set of key metrics for proposing a predictive model for virtual, augmented and mixed reality (MR) acceptance by users. This model is called the extended TAM for MRDT adoption in the architecture, engineering, construction and operations (AECO) industry. Design/methodology/approach An interpretivist philosophical lens was adopted to conduct an inductive systematic and bibliographical analysis of secondary data contained within published journal articles that focused upon MRDT acceptance modelling. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) approach to meta-analysis were adopted to ensure all key investigations were included in the final database set. Quantity indicators such as path coefficients, factor ranking, Cronbach’s alpha (a) and chi-square (b) test, coupled with content analysis, were used for examining the database constructed. The database included journal papers from 2010 to 2020. Findings The extant literature revealed that the most commonly used constructs of the MRDT–TAM included: subjective norm; social influence; perceived ease of use (PEOU); perceived security; perceived enjoyment; satisfaction; perceived usefulness (PU); attitude; and behavioural intention (BI). Using these identified constructs, the general extended TAM for MRDT in the AECO industry is developed. Other important factors such as “perceived immersion” could be added to the obtained model. Research limitations/implications The decision to utilise a new technology is difficult and high risk in the construction project context, due to the complexity of MRDT technologies and dynamic construction environment. The outcome of the decision may affect employee performance, project productivity and on-site safety. The extended acceptance model offers a set of factors that assist managers or practitioners in making effective decisions for utilising any type of MRDT technology. Practical implications Several constraints are apparent due to the limited investigation of MRDT evaluation matrices and empirical studies. For example, the research only covers technologies which have been reported in the literature, relating to virtual reality (VR), augmented reality (AR), MR, DT and sensors, so newer technologies may not be included. Moreover, the review process could span a longer time period and thus embrace a fuller spectrum of technology development in these different areas. Originality/value The research provides a theoretical model for measuring and evaluating MRDT acceptance at the individual level in the AECO context and signposts future research related to MRDT adoption in the AECO industry, as well as providing managerial guidance for progressive AECO professionals who seek to expand their use of MRDT in the Fourth Industrial Revolution (4IR). A set of key factors affecting MRDT acceptance is identified which will help innovators to improve their technology to achieve a wider acceptance.
