Sustainable development can be attained at a microlevel and having smart campuses around the world presents an opportunity to achieve city-wide smartness. In the process of attaining smartness on campuses, the elements requiring attention must be investigated. There are many publications on smart campuses, and this investigation used the bibliometric analysis method to identify such publications produced over the last decade. A matrix of 578 nodes and 3217 edges was developed from 285 publications on smart campus construction and procurement. Fifteen cluster themes were produced from the bibliometric analysis. The findings revealed that China contributed 48.4% of all published articles on the smart campus. The findings presented a framework from the cluster themes under the four broad infrastructure areas of building construction or repurposing, technology and IT network, continuous improvement, and smart learning and teaching management. The implications of the findings identified that IT project management, traditional procurement strategy, and standard forms of contracts such as the New Engineering Contract (NEC) and the Joint Contract Tribunal (JCT) are applicable in the procurement of smart cities.

This study explores the behavioural safety measures for addressing accidents on Qatar mega projects which are infamous for their high rates of accidents and fatality. Using extant literature and brainstorming as sources of preliminary information, questionnaire was used for collecting quantitative data, which was analysed using reliability analysis and exploratory factor analysis.

The recent decade has seen increased attention focused on understanding category formation–a cognition ability of preschool aged children. Children organize their knowledge about real-world objects by categorizing them under some common properties or functions. The advancement and popularity of mobile devices with touch screens provide a good opportunity for young children to learn and practice. In this study, an approach that models structural and functional categorization knowledge for developing mobile learning systems with dynamic categorization exemplars is proposed. A mobile application was implemented based on the proposed model for pre-schoolers (aged 3–6 years). Moreover, the quasi-experimental pre-test and post-test method was used to evaluate the effectiveness of the proposed knowledge-based application in terms of categorization ability learning. The results show that the children who experienced dynamically created categorization exemplars from the modelled knowledge achieved increased scores compared to those who followed the traditional teaching using books and worksheets.

Purpose The increasing awareness of stress as an issue in the construction industry, and the increased realisation of the more effective approach of preventing stress as opposed to treating mental health, has placed a great responsibility on industries that rely heavily on the performance of their workforce. In line with this, this paper aims to investigate the causes of stress and the best strategies for improving professional resilience and stress management proficiency in the construction industry. Design/methodology/approach Using exploratory sequential mixed method research design, the top factors that cause stress, mitigate stress and build resilience are identified and discussed. Findings The findings show thematic similarities in the causes of stress, by displaying a reoccurring theme relating to the quality and lack of information, as well as poor communication among the construction professionals. This implies that poor collaboration and “over-the-wall syndrome” of the construction industry does not only contribute to defective output and reworks, it also has significant impacts on the health and well-being of the professionals. Recommendations are made on how to mitigate stress in the industry, by addressing its root-causes and implementing the identified mitigation strategies. This includes a realistic approach to budgeting and project duration, as well as improved communication and collaboration. Originality/value Finding of this study could help in mitigating stress and mental health concerns that are currently plaguing the construction industry.

The study investigates the factors contributing to the menace of Alcohol and Substance Misuse (ASM) in the construction industry, and its mitigation. Sequential exploratory mixed method design, involving interview and questionnaire were used for collecting data that were subsequently analysed using thematic analysis, factor analysis and Kruskal-Wallis test. Findings suggest that the problem of ASM is largely caused and exacerbated by mental strain, site working conditions, male dominance and ineffective HR management. Screening and educational approaches were confirmed as the carrot and stick methods for mitigating the menace in the construction industry. The finding implies that by making construction companies more accountable for the wellbeing of their workers, a change could be brought in the industry. These changes could be incentivised by initiatives like PREVENT to mitigate the crisis currently endemic in construction. The study suggests some practical measures for tackling the menace of ASM that is bedevilling the construction

Despite the increasing significance of embodied impacts of buildings, efforts to reduce their environmental footprints have been concentrated on the operational impacts of buildings. This study investigates the changing significance of embodied carbon over the entire life cycle of whole buildings. A case study of an office building was modelled with Revit, and sensitivity analyses of the modelled building were performed by varying the material specification and energy use pattern for seven other typologies. Using Revit, BIMWASTE tool, ATHENA Impact Estimator and Green Building Studio, comparative life-cycle analyses were carried out for the eight building typologies. The study suggests that notwithstanding the enormous impacts of the operational stage on life-cycle carbon of fossil fuel-based buildings, embodied impacts could vary between 8.4% and 22.3%. A key determinant of the proportional impacts of embodied energy is the nature of materials used for building construction. Similarly, embodied impacts of buildings become more significant and could contribute up to 60% of their life cycle impacts as they become more energy-efficient during their operational stage. As the study confirms the varying significance of embodied energy as construction materials and energy use patterns change, it implies the need for policy measures based on a whole life assessment methodology, instead of the usual ways of giving sole importance to the operational impacts of buildings. With buildings becoming more energy-efficient during their operational stage, there is an urgent need for an increased focus on the embodied impacts of buildings, especially as renewable energy resources are becoming widely adopted.

The need to use Building Information Modelling (BIM) for Construction and Demolition Waste (CDW) minimisation is well documented but most of the existing CDW management tools still lack BIM functionality. This study therefore assesses the expectations of stakeholders on how BIM could be employed for CDW management. After a review of extant literature to assess the limitations of existing CDW management tools, qualitative Focus Group Interviews (FGIs) were conducted with professionals who are familiar with the use of BIM to understand their expectations on the use of BIM for CDW management. The 22 factors identified from the qualitative data analyses were then developed into a questionnaire survey. The exploratory factor analysis of the responses reveals five major groups of BIM expectations for CDW management, which are: (i) BIM-based collaboration for waste management, (ii) waste-driven design process and solutions, (iii) waste analysis throughout building lifecycle, (iv) innovative technologies for waste intelligence and analytics, and (v) improved documentation for waste management. Considering these groups of factors is key to meeting the needs of the stakeholders regarding the use of BIM for CDW management. These groups of factors are important considerations for the implementation and acceptance of BIM-based tools and practices for CDW management within the construction industry.
