Purpose The current movement toward digitisation has promoted the adoption of smart building technology globally. Despite its advantages, its usage in developing countries such as Nigeria is still very low. Therefore, the purpose of this paper is to investigate construction professionals' awareness of smart building concepts (SBCs) in the Nigerian construction industry and identify the parameters by which SBCs can be measured. Design/methodology/approach A quantitative survey was carried out using a questionnaire to gather relevant data in the study area. This paper was conducted on 363 registered construction professionals in the Nigerian construction industry. The collected data were analysed using descriptive statistics and Kruskal–Wallis H test analysis. Findings This paper indicated that the majority of Nigerian construction professionals are aware of SBCs. Furthermore, the Kruskal–Wallis H test shows no significant difference between the awareness level of the various construction professionals. This paper further revealed energy management systems, IT network connectivity, safety and security management systems and building automation systems as the most significant parameters in which SBCs can be measured. Practical implications This paper identified significant parameters influencing SBCs awareness in the Nigerian construction industry. These parameters can be integrated into the building during the design stage and can be incorporated into the policymaking process of construction firms to promote the awareness of SBCs and encourage practices related to construction sustainability. Originality/value This paper provides empirical evidence on the awareness of SBCs among construction professionals and significant parameters influencing awareness in the Nigerian construction industry.

Purpose Sandbag building technologies (SBTs) have been offered as a cost-effective and sustainable alternative building technology (ABT) capable of accelerating house construction in South Africa, but its acceptance remains low. However, knowledge about how to effectively improve SBT social acceptance is limited. This study aims to develop and prioritise SBT social acceptability strategies towards providing a comprehensive framework for the successful deployment and widespread adoption of sandbag technology. Design/methodology/approach This study used a quantitative research strategy that included a literature review and a structured questionnaire survey of 228 ABT professionals and stakeholders in the South African housing industry. The study statistically analysed 13 strategies for the social acceptance of SBT. Findings The analysis showed that the top three strategies include the availability of sandbag demonstration projects in all provinces, the approval of a sandbag building code and the availability of standard design methods for earthbags. A factor analysis clustered the 13 strategies into Stakeholders integration and policy formation, Effective education and knowledge sharing and Grassroots advocacy and incentives. Practical implications The current study’s findings provide a broad framework for the effective implementation and wide acceptance of sandbag technology in housing projects. It offered certain best practices that policymakers and practitioners might use to promote ABT and SBT societal acceptability. Originality/value To the best of the authors’ knowledge, the study represents the first and only attempt to investigate the viewpoints of experts and housing market stakeholders in South Africa regarding sandbag technology social acceptance strategies and contributes to the social acceptance body of knowledge in ABT and SBT.

Purpose The unexpected spread of COVID-19 rapidly switched from a health crisis to an economic one. The Architectural, Engineering and Construction (AEC) industry experienced drastic impacts, especially in Africa. Several studies investigated COVID-19 impacts on the AEC industry, but very few were conducted in Africa. This study aims to cover this gap, address detailed overview of negative and positive impacts of COVID-19 on the AEC field, especially in the different African regions, and highlight their causes and the measures taken to overcome them. Design/methodology/approach The authors combined a Preferred Reporting Items for Systematic Reviews and Meta-Analyses-based Systematic Literature Review (SLR) and a survey involving 87 AEC companies operating in Africa. The SLR initially used four scientific databases; however, considering the limited Africa-related found data, institutional and governmental databases were also included. Findings Globally, implementing the mandated restrictive measures against COVID-19 caused significant losses for developers, designers and contractors but helped the information and communication technologies operators to thrive. In the five African regions, the AEC industry experienced 22 heavy impacts that can be split into four categories: financial, managerial/strategic, operational and opportunities. This paper thoughtfully explains the causes of COVID-19 impacts and presents the undertaken measures by the African private and public sectors to overcome them. Generally, the African AEC industry lost 51% of the total sales in 2020. Originality/value This paper contains all aspects related to health hazard influences on the AEC industry, especially in Africa. Researchers and decision-makers may use it to build new approaches or strategies related to risk management or design technological solutions.

Purpose Construction projects require a range of documents (e.g. drawings and specifications) prepared by built environment professionals. In recent years, there has been a perception amongst professionals that quality of documentation has declined. “Low” professional fees were cited as one of the reasons for poor quality documentation. However, most studies on the topic contained inappropriate methodologies. Therefore, the purpose of this paper was to develop a conceptual methodology to comprehensively examine the relationship between fees and professional service output quality. Design/methodology/approach A systematic literature review (SLR) was conducted to evaluate the limitations of previous methodologies and identify variables in the relationship between fees and quality of professional service outputs. Findings from the SLR were used to develop a conceptual methodology to investigate the relationship between fees and quality of professional service outputs. Findings Based on a frequency analysis of factors in the construction literature, the three main variables influencing professional service output quality were fees, coordination and amount of time available for project tasks. The SLR and shortcomings in previous studies informed the development of a conceptual methodology to examine the relationship between fees and professional service output quality. Practical implications The conceptual methodology will assist in comprehensively investigating the effect of fees on the quality of professional service outputs. This is particularly relevant in countries where clients procure built environment professional services based on the lowest fee tendered but are concerned about quality. The methodology can establish how and to what extent “low” fees impact on professional service output quality. Industry professionals can also use variables identified in this paper to mitigate quality-related risks when producing professional service outputs. Originality/value This paper adds to the body of knowledge by identifying variables in the relationship between fees and professional service output quality. The identified variables can be monitored and controlled by researchers during future investigations. Additionally, a conceptual methodology was proposed to assist researchers to determine the effect of fees on professional service output quality. The flexibility of the conceptual methodology enables it to comprehensively investigate other key variables (apart from fees) impacting on professional service output quality.

Purpose The utilisation of building information modelling (BIM) technology is rapidly increasing among construction professionals across the world. Notwithstanding, recent studies revealed a low level of BIM implementation in the context of the Nigerian construction sector. Moreover, previous studies have established that BIM application comes with its share of various barriers. Therefore, this study aims to carry out an on-site survey on barriers to the application of BIM on construction sites in the Nigerian construction industry. Design/methodology/approach An extensive review of literature on BIM barriers was conducted, from where 33 factors were identified as significant BIM barriers peculiar to the developing countries. A questionnaire was developed and distributed to the targeted respondents, who are practicing professionals in the Nigerian construction industry, based on the identified barriers. The data collected were analysed by using both descriptive and inferential statistics. Findings The principal component analysis revealed that 27 barriers were peculiar to the Nigerian construction industry. The “lack of familiarity with BIM capacity, habitual resistance to change from the traditional style of design and build, and poor awareness of BIM benefit” were identified as the three most critical barriers hindering BIM application on construction sites in the Nigerian construction industry. Practical implications This study reveals key information on the peculiar barriers to BIM application in the Nigerian construction industry. The avoidance of these barriers will not only assist various construction stakeholders in the successful implementation of BIM application on a construction project but also promote information management systems and productivity within the construction industry to a great extent. These will further improve post-construction activities. Originality/value This study provides a substantial understanding of BIM state of the art in the context of barriers hindering BIM application on construction sites in the Nigerian construction industry.

Purpose This study aims to compare and evaluate the application of commonly used machine learning (ML) algorithms used to develop models for assessing energy efficiency of buildings. Design/methodology/approach This study foremostly combined building energy efficiency ratings from several data sources and used them to create predictive models using a variety of ML methods. Secondly, to test the hypothesis of ensemble techniques, this study designed a hybrid stacking ensemble approach based on the best performing bagging and boosting ensemble methods generated from its predictive analytics. Findings Based on performance evaluation metrics scores, the extra trees model was shown to be the best predictive model. More importantly, this study demonstrated that the cumulative result of ensemble ML algorithms is usually always better in terms of predicted accuracy than a single method. Finally, it was discovered that stacking is a superior ensemble approach for analysing building energy efficiency than bagging and boosting. Research limitations/implications While the proposed contemporary method of analysis is assumed to be applicable in assessing energy efficiency of buildings within the sector, the unique data transformation used in this study may not, as typical of any data driven model, be transferable to the data from other regions other than the UK. Practical implications This study aids in the initial selection of appropriate and high-performing ML algorithms for future analysis. This study also assists building managers, residents, government agencies and other stakeholders in better understanding contributing factors and making better decisions about building energy performance. Furthermore, this study will assist the general public in proactively identifying buildings with high energy demands, potentially lowering energy costs by promoting avoidance behaviour and assisting government agencies in making informed decisions about energy tariffs when this novel model is integrated into an energy monitoring system. Originality/value This study fills a gap in the lack of a reason for selecting appropriate ML algorithms for assessing building energy efficiency. More importantly, this study demonstrated that the cumulative result of ensemble ML algorithms is usually always better in terms of predicted accuracy than a single method.

Purpose Energy-saving is a growing challenge worldwide because of population growth, economic activity and high consumption rates that are unsustainable in the long term. Health-care facilities and hospitals face the challenge of increases in operational costs. This paper aims to appraise challenges to adopting energy-saving policies and proposes a roadmap for sustainability and energy efficiency management in hospitals and health-care facilities. Design/methodology/approach Eight hospitals were examined as case studies through qualitative interviews with hospital senior management, executives and health-care facilities managers in addition to collecting relevant data from the literature; there is critical appraisal and content analysis of this data. Findings This study established factors influencing implementation and challenges to energy-saving strategies. This study proposed guidelines for efficient energy management in hospitals and health-care facilities. This study concluded that the best performance is secured by integrating the proposed guidelines with the adoption of ISO 50001 energy management systems to achieve the United Nations’ sustainable development goal – SDG 7 “affordable and clean energy”. Research limitations/implications This study is limited to the initiatives/experiences of the hospitals studied in the Middle East and North Africa region. Originality/value This study’s findings, conclusions, recommendations and proposed guidelines enrich the body of knowledge. This will allow industry key stakeholders, hospitals and health-care facilities managers to overcome challenges of implementing energy management. In addition, adopting the proposed guidelines will improve energy efficiency and help hospitals in green initiatives as they seek to demonstrate their support for United Nations’ sustainable development goals.

Purpose This study aims to raise awareness of the key challenges, opportunities and priorities for evidence-based strategies’ application to inform building and urban design decisions. Design/methodology/approach This study uses deductive qualitative content and manifest analysis, using semi-structured interviews undertaken with building and urban design professionals who represent a UK-based organisation. Findings The challenges associated with the practical implementation of frameworks, potential application areas and perceived areas of concern have been identified. These not only include the need to practically test their use, but also to identify the most appropriate forums for their use. Participant responses indicate the need to further develop engagement strategies for their practical implementation, clearly communicating the benefits and efficiencies to all stakeholders. Research limitations/implications Implications/ limitations of this study come with the fact that some of the respondents may possess inadequate professional experience in properly evaluating all the questions. Additionally, the information gathered is restricted to the UK geographical context, as well as coming from one organisation, because of data accessibility. Practical implications The findings of the study can be adopted by designers in the strategic definition level to overcome the key challenges associated with the use of evidence-based strategies, enhancing their decision-making processes. Originality/value As a theoretical contribution to knowledge, this study enhances the body of knowledge by identifying the challenges associated with the practical implementation of evidence-based strategies to inform building and urban design decisions. In practice, the findings aid urban planners, designers and academics in embedding and adopting strategies that enhance decision-making processes.

Purpose Master information delivery plan (MIDP) is a key requirement for building information modelling (BIM) execution plan (BEP) that enlists all information deliverables in BIM-based project, containing information about what would be prepared, when, by who, as well as the procedures and protocols to be used. In a well-conceived BEP, the MIDP facilitates collaboration among stakeholders. However, current approaches to generating MIDP are manual, making it tedious, error-prone and inconsistent, thereby limiting some expected benefits of BIM implementation. The purpose of this study is to automate the MIDP and demonstrate a collaborative BIM system that overcomes the problems associated with the traditional approach. Design/methodology/approach A BIM cloud-based system (named Auto-BIMApp) involving naming that automated MIDP generation is presented. A participatory action research methodology involving academia and industry stakeholders is followed to design and validate the Auto-BIMApp. Findings A mixed-method experiment is conducted to compare the proposed automated generation of MIDP using Auto-BIMApp with the traditional practice of using spreadsheets. The quantitative results show over 500% increased work efficiency, with improved and error-free collaboration among team members through Auto-BIMApp. Moreover, the responses from the participants using Auto-BIMApp during the experiment shows positive feedback in term of ease of use and automated functionalities of the Auto-BIMApp. Originality/value The replacement of traditional practices to a complete automated collaborative system for the generation of MIDP, with substantial productivity improvement, brings novelty to the present research. The Auto-BIMApp involve multidimensional information, multiple platforms, multiple types and levels of users, and generates three different representations of MIDP.

Purpose This paper aims to critically evaluate the impact of empowering leadership on safety behavior and safety climate during safety monitoring at a nuclear power plant (NPP) in the United Arab Emirates (UAE). Design/methodology/approach Data were collected using questionnaires filled out by 500 participants from the UAE nuclear sector. The relationships among the variables were analyzed using structural equation modeling. Findings The results indicated that empowering leadership has a positive impact on safety behavior, and a positive safety climate leads to increased levels of safety behavior (compliance and participation). The results also showed that safety climate partially mediates the relationship between empowering leadership and safety behavior. Originality/value This study contributes to the existing knowledge regarding empowering leadership, safety monitoring, behavior and climate. Because limited information is available on this topic, this study extends the research on the relationship between empowering leadership and safety research at an NPP. Specifically, it outlines that safety monitoring partially mediates the relationship between empowering leadership and safety behavior. This research enables NPPs worldwide to incorporate empowering leadership to enhance safety monitoring and ensure better safety behavior and climate.
