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.

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.

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.

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.

In the last two decades, value management (VM) has become an established construction practice based on fundamental approaches. Implementation of VM activities can contribute to enhancement of the initial objectives in terms of cost, quality, and time. However, the VM activities adopt informal approaches in the Egyptian construction industry. This study aims to develop a VM implementation model by investigating the relationship between VM implementation and the overall project success (OPS) in Egyptian building projects. Fifteen experts were interviewed to assess the VM activities obtained from previous studies. Exploratory factor analysis (EFA) was used to validate the results from the interviews. Structured questionnaires completed by building professionals were further employed to investigate the importance of these VM activities. Partial least squared structural equation modeling (PLS-SEM) was used to determine and confirm the factors structure and examine the relationships between the VM implementation and OPS. The results showed a moderate association, with the implementation of the VM contributing 55.5% to the success of the project. The findings can be used as a benchmark for decision-makers to minimize costs and boost efficiency by implementing VM in the Egyptian construction industry. This study advances the current construction engineering management by improving the understanding of VM methods and activities.

This study investigates and ranks the critical capacity building challenges (CBC) impacting the Tanzanian public–private partnerships (PPPs) projects. The strength of interactions between CBC is established, with practical solution proposals offered and benchmarked with previous studies. A total of 8 CBC were identified from a scoping review. Data was then collected from 81 PPP practitioners, and subjected to descriptive and inferential statistics. The results demonstrated a disparity of ranking of the 8 CBC among those with and without PPP experience, with the most highly ranked 4 CBC identified as ‘limited local people with experience’, ‘lack of resources’; ‘lack of successful PPP projects’, and ‘lack of permanent PPP trainers’. The least ranked was ‘lack of political will for promoting PPPs’. Strong and positive correlation between ‘inadequate qualifications’ and ‘lack of hands-on training’ was established. Suggested solutions were broadly classified in the following four categories: (1) Training and education; (2) Benchmarking and lessons learnt; (3) Knowledge transfer and experience sharing; and (4) Institutional reforms; and supportive enabling environments. The results of this study foster better understanding of the facets of capacity building, provides PPP stakeholders with solutions for mitigating and addressing the challenges during the PPP project lifecycle.

Purpose This study aims to excoriate, define and delineate the main drivers of “change” in commercial construction projects and generate guidelines on how to minimise exposure to the associated adverse effects upon project stakeholders. Design/methodology/approach The research adopts mixed doctrines through a combination of epistemological lenses, embracing two primary philosophical stances: interpretivism, to identify the primary drivers of change based on a systematic literature review and a post-positivist, inductive approach to analyse the results of change within a Joint Contracts Tribunal (JCT) Design and Build (D&B) construction project case study. Findings The causal nexus of change during the construction phase is assessed and delineated; the key affecting factors are thematically grouped under headings: extent and severity; time in relation to implementing; instigating party; individual(s) responsible for managing the change; reason for the change; available resource; recoverable or non-recoverable; contract/project type; and type of client. Following this, the effects of change on key elements of the project are encapsulated and recommendations for adaptations which may provide improved experiences are offered. Originality/value The study tackles the common issue of managing the deleterious effects of change on commercial construction projects, defining management techniques to minimise stakeholder tribulation.

Purpose Building information modelling (BIM) has had a significant impact on the architecture, engineering and construction (AEC) sector in the past several years. However, not much is published concerning small and medium-sized enterprises (SMEs) adopting BIM in the construction industry. To address this knowledge gap, a complete and in-depth literature review of the adoption of BIM by SMEs in the AEC sector is conducted in this study. The paper also provides a comprehensive review of the mainstream studies of adoption of BIM in the AEC organisations. Design/methodology/approach Based on a five-stage literature review, 54 articles on the adoption of BIM by SMEs from the period 2009 to 2019 were critically analysed from the following three perspectives: (1) the number of articles produced; (2) the research focus and (3) the author's contributions. The techniques of the visualisation of similarities (VOSviewer) software were used to analyse the citation networks of the 54 articles as identified. Findings From the analysis, it was established that the number of studies on BIM adoption by SMEs in the reviewed journals has not been increasing and not many articles are available. The finding makes the argument that BIM adoption by SMEs is not a focus point but rather the adoption and implementation of BIM is generalised in the AEC sector. In addition, the results revealed that most of the published articles come from the United Kingdom (UK). However, this finding is hardly surprising due to the requirements in the UK, which have made the adoption of BIM mandatory on all publicly funded projects and are at level 2 BIM. The other highly ranked countries by origins of studies on the adoption of BIM by SMEs were found to be Australia and the United States of America (USA), all of which are developed nations or economies. Some key BIM in SME research trends (adoption, enforcement, benefits, strategies, skills gap, awareness, education and training, and technology) were identified and evaluated. Research limitations/implications The results presented in this journal are only applicable to SMEs in the AEC sector. As a result of little available literature on the adoption of BIM in developing countries, the articles have been drawn from developed countries. The dataset was mainly extracted from the Scopus database for the analysis. Originality/value An accomplished series content analysis of the implementation and adoption of BIM by SMEs from international construction journals were reported. The study makes significant and emergent contribution by building on the foundation of BIM research in SMEs as well as providing a reference point for the interpretation of findings, as well as directions for future research.

Sustainability principles should be implemented during all the phases of the decision-making process of constructing residential buildings to achieve maximum gains without compromising the function of such projects. This study identified and examined the critical success factors (CSFs) required for implementing value management (VM) in residential building projects. With a view to the sustainability of such the projects. The CSFs for VM were identified from previous studies, which were then contextually adjusted using both semi-structured interviews and a pilot study via the Exploratory Factor Analysis (EFA) technique. The EFA results showed that the VM CSFs could be categorized into four constructs: stakeholders and knowledge, culture and environment, workshop dynamics, and standardization. Questionnaires were then administered to 214 building stakeholders within the Egyptian building industry. Partial least square structural equation modelling (PLS-SEM) was used to develop the CSFs model. Despite that Egyptian professionals with limited practice experiences were quite knowledgeable about VM, results showed that stakeholders and knowledge were crucial CSFs for implementing VM. The results of this study will be a guide for decision-makers to reduce costs and improve sustainability by introducing VMs in the Egyptian construction industry.

Value management (VM) is one of the principles adopted by stakeholders to manage issues in the building industry. This paper aims to examine VM diffusion between residential building entities in the Egyptian residential building industry. This research was confined to the Cairo and Giza regions, with enough residential building experience from clients, consultants, and contractors. A quantitative questionnaire survey was generated to find answers from those active in the residential building industry. The results show that although VM’s most widely practiced activities in the Egyptian construction industry are only information phase activities, professionals in Egyptian building projects agreed that all VM activities are important. The results also demonstrated that there is a significant positive correlation among VM phases. The results constitute activities for the adoption of VMs in Egypt. Its guidelines will dramatically enhance the implementation of VMs both in Egypt and in other developing countries where similar projects are conducted. Finally, this research strengthens the residential building industry’s present management by enhancing VM tools and elements to generate value for money.

Purpose Despite the fact that extensive studies on public-private partnerships have focused on risk identification and classification, research still lacks concentration on studying the latent structure of risks in build operate transfer (BOT) transportation projects, especially in developing countries. The research was carried out in Vietnam and this paper aims to explore the underlying relationships among risks in the context of BOT transportation projects. Design/methodology/approach A questionnaire survey was conducted to investigate the perception of stakeholders regarding the probability of occurrence and the severity of the impact of risks related to BOT transportation projects. Factor analysis was performed based on a total of 40 risks. Findings Seven risk groups were formed as a result of factor analysis, namely, “projects’ viability and political-regulatory risks”, “macroeconomic risks”, “projects’ feasibility study and market risks”, “financial risks”, “organization/coordination and force majeure risks”, “tolling, contractual, approvals risks” and “media and land expropriation risks”. Originality/value The research contributes to the current body of knowledge by providing deep insight into the structure of risks in BOT transportation projects in Vietnam through exploring the underlying relationships among risks, to form a latent risk structure from practical viewpoints. The findings are beneficial for involved stakeholders and policymakers to set up and propose suitable management strategies and related policies.
