Purpose This study aims to explore the influential role stakeholder play in the management of indoor environmental quality (IEQ) in facilities of higher education institutions (HEIs) in South Africa. By defining the indoor environmental challenges facing HEI's, an alternative redress to these challenges can be achieved through stakeholder management. Design/methodology/approach The study adopted a quantitative survey approach which was informed by a post-positivism philosophical stance. The closed-ended questionnaire survey was used to gather views from academic and administrative staff who were employed in various HEIs across South Africa. The literature review revealed 13 influential stakeholder management roles which were explored. The gathered data was analysed using descriptive and inferential statistics that evaluated the influential role stakeholder play in the management of IEQ in HEIs. Findings Exploratory factor analysis (EFA) revealed three core categories of stakeholder management roles to being community engagement and awareness, organisational commitment and objective function. These roles play an integral part of overhauling the current IEQ conditions in HEIs, which subsequently improves the quality of education through efficient academic and administrative performance. Originality/value The study contributes to the body of knowledge as it reveals that HEI, particularly in developing countries like South Africa, can improve their current IEQ conditions through adopting critical stakeholder management roles. Also, this study provides further theoretical background for future research in the area of stakeholder management which has been lacking in previous IEQ studies.

Building information modelling (BIM) has become a common denominator for information management, efficiency, collaboration, and productivity in the construction industry. The adoption of building information modelling has been assessed to be unequal in the construction industry the world over. It has been observed that developing countries are struggling with BIM adoption and are at a beginner stage in the process. Meanwhile, there have been different research efforts focused on advancing BIM diffusion in developing countries. This study focused on reviewing the research trend and knowledge domains of BIM research in developing countries. The study analysed scholarly publications from selected developing countries sourced from the Scopus database from 2005 to 2019; the study covered BIM research efforts since their commencement in developing countries. The study identified the different research trends and the current focus through visualisations using VOS viewer software. The most influential and productive researchers were also identified. This research contributes to the extant body of knowledge by synthesizing the state of the art of BIM research in developing countries. Furthermore, it provides the pre-COVID-19 BIM diffusion status in developing countries.

This study provides a holistic assessment of the current waste management strategies implemented in Nigerian construction projects. The data used in this study were collected from both primary and secondary sources. The primary data were collected through survey questionnaires distributed via emails of the targeted respondents who are construction professionals in the study area of Lagos metropolis, while the secondary data were collected via the review of related literature. Out of the 200 questionnaires distributed, only 168 valid forms were retrieved. The collected data accounted for 84% of the entire survey and were suitable for the analysis. An exploratory factor analysis was conducted while the reliability of the research survey instrument was tested using Cronbach’s alpha coefficient reliability. The result indicated that the waste management strategies were clustered into three groups, comprising practical legal framework and modular construction, sustainable procurement and material optimisation, and proper construction detailing and design. In conclusion, the waste management strategies implemented in Nigeria were assessed as being “not sustainable enough”. However, it is recommended that there is an upgrading in either the approach or method of application of waste management strategies in order to ensure its sustainability.

Automatic anomaly detection monitoring plays a vital role in water utilities’ distribution systems to reduce the risk posed by unclean water to consumers. One of the major problems with anomaly detection is imbalanced datasets. Dynamic selection techniques combined with ensemble models have proven to be effective for imbalanced datasets classification tasks. In this paper, water quality anomaly detection is formulated as a classification problem in the presences of class imbalance. To tackle this problem, considering the asymmetry dataset distribution between the majority and minority classes, the performance of sixteen previously proposed single and static ensemble classification methods embedded with resampling strategies are first optimised and compared. After that, six dynamic selection techniques, namely, Modified Class Rank (Rank), Local Class Accuracy (LCA), Overall-Local Accuracy (OLA), K-Nearest Oracles Eliminate (KNORA-E), K-Nearest Oracles Union (KNORA-U) and Meta-Learning for Dynamic Ensemble Selection (META-DES) in combination with homogeneous and heterogeneous ensemble models and three SMOTE-based resampling algorithms (SMOTE, SMOTE+ENN and SMOTE+Tomek Links), and one missing data method (missForest) are proposed and evaluated. A binary real-world drinking-water quality anomaly detection dataset is utilised to evaluate the models. The experimental results obtained reveal all the models benefitting from the combined optimisation of both the classifiers and resampling methods. Considering the three performance measures (balanced accuracy, F-score and G-mean), the result also shows that the dynamic classifier selection (DCS) techniques, in particular, the missForest+SMOTE+RANK and missForest+SMOTE+OLA models based on homogeneous ensemble-bagging with decision tree as the base classifier, exhibited better performances in terms of balanced accuracy and G-mean, while the Bg+mF+SMENN+LCA model based on homogeneous ensemble-bagging with random forest has a better overall F1-measure in comparison to the other models.

Infrastructure plays a crucial role in the economic growth and development of any country; therefore, it is important to ensure adequate investments for the delivery of infrastructure services. This paper assessed factors affecting the development of sustainable infrastructure in South Africa. The identified factors can be utilised by government as reference to enhance the delivery of sustainable infrastructure. To achieve the objective of the study, Quantitative data was collected. The study used a sample size of 57 out of the 65 questionnaires (a response rate of 87.7%) which were answered by professionals in the built environment viz. Architects, Property Developers, Quantity Surveyors, Engineers, Construction and Project Managers. The data collected was then analysed and interpreted using IBM Statistical Package for Social Science (SPSS) computer software to provide mean item scores, standard deviations and Cronbach's alpha. Given the explored factors which affect the delivery of sustainable infrastructure, the results have established that due to developers habit of building to maximise profit only, not for end-users' comfort and the initial high cost required to develop sustainable infrastructure were the major factors that affect the delivery of sustainable infrastructure. It is recommended that the government develop clear, stable and credible policies that will attract investors who will be committed to inject financial resources into infrastructure development and alter the existing building regulations to complement the sustainable development goals.

Implementation of renewable energy technologies will prevent damages caused by overreliance on fossil fuels, improve the health of the public, maximize job creation because they produce little or no atmosphere pollutants. To encourage the adoption of renewable energy in the built environment, this study investigated the means of promoting the integration of renewable energy. Quantitative research approach was adopted and a well-structured questionnaire survey was designed. The survey was conducted using construction professionals in Gauteng province of South Africa. From the 155 questionnaires distributed, 103 were retrieved which represents 67% response rate. The retrieved data were analysed using descriptive and inferential statistical procedures. The findings revealed that training and education of professionals, energy sector reforms and awareness creation are the highly ranked drivers of renewable energy integration. The drivers were further factored into clusters using exploratory factor analysis. This yielded three clusters namely collaborative action, government’s action, and policies and economic action with collaborative action accounting for the larger variance of the factors. The study concluded that moving towards renewable energy technologies is the best way to supply an environmentally friendly and affordable energy to all people. This study recommended that policies/regulations should be put in place by the government to keep users of non-renewable energy in check.

As a result of pollution, deforestation and other environmental challenges, construction process and activities has contributed in no small measure to environmental degradation. One of the fundamental tripod of sustainability is keeping the environment safe for the inhabitants. This study, therefore, examines the impact of construction activities on the environment with a view to highlighting mitigation approaches and their enforcement strategies. A quantitative research methodology was adopted, and convenient sampling technique was employed to gather information from primary sources. Questionnaires were administered on construction professionals which include architects, quantity surveyors, engineers, safety officers, as well as construction and facility managers. Construction activities impact badly on the environment due to waste generation, resource consumption, noise pollution, air pollution due to dust from construction activities, as well as bad odours from large diesel-powered vehicles/construction machinery. Although, some of these impacts cannot be completely eradicated, there are a number of approaches that could be used to mitigate them, these include Environmental Impact Assessment (EIA), green building (sustainable construction), Quantitative Risk Assessment (QRA), Environmental Management System (EMS), and Environmental Protection Agency (EPA). Therefore, an effort should be made by government and construction stakeholders to efficiently incorporate and enforce the available approaches/initiatives through constant monitoring of construction process from start to completion and legislative laws that spell out punishment as response to violations. Awareness, learning, and trainings of construction stakeholders on the impacts of building construction activities on the environment is also recommended.

This chapter presents an analysis of the descriptive data with specific focus on tenants’ perception and reactions to a residential property with a grave. The chapter provides a simple assessment of the impact of a grave on tenants’ residential choice and rent. However, the findings from such analyses are not always sufficient where parameter estimates require absolute precision. Therefore, this chapter presents and analyse the stated choice data using two rigorous statistical tools for parameter estimation.
