Notes that the management of subsidence cases often involves both engineering consultants and contractors. In order to obtain information on current trends in subsidence management, a survey of both consultants and contractors who deal with subsidence cases was undertaken. Presents the findings of the survey which highlight both elements of good practice and areas for improvement. Also reveals inconsistencies in the procedures adopted by different firms as well as differences between the approaches adopted by consultants and contractors. The results of the survey are being incorporated into the development of a knowledge‐based system for the management of subsidence cases.

Cyber-physical systems (CPS) offer improved delivery of facilities management (FM) mandates through their advanced computational capabilities. Using second-order multivariate analysis, this study explores the drivers of the espousal of this digital technology for FM.

The study employed a deductive approach underpinned by a post-positivist philosophical stance using a quantitative technique aided by a well-structured questionnaire. Data retrieved from the study’s respondents were analysed with descriptive statistics, Kruskal–Wallis h-test, exploratory factor analysis and confirmatory factor analysis.

The result of the analysis conducted portrayed evidence of convergence and good measures while the estimated model parameters all attained prescribed fit indexes. Also, it was revealed that the most influential drivers for the uptake of CPS for FM mandates are resource allocation for system procurement, top management willingness, system stability and compatibility with the previous system.

The study’s findings unravel the necessitated parameters that would instigate the adoption of CPS for the delivery of FM activities by organisations while also propelling the digital transformation of construction project delivery at the post-occupancy phase.

This is the first study to empirically assess the propelling measures for incorporating CPS for FM using second-order multivariate analysis. Consequently, the study's outcome helps close this knowledge gap.

Through its advanced computational capabilities, cyber–physical systems (CPS) proffer solutions to some of the cultural challenges plaguing the effective delivery of facilities management (FM) mandates. This study aims to explore the drivers for the uptake of CPS for FM functions using a qualitative approach – the Delphi technique.

Using the Delphi technique, the study selected experts through a well-defined process entailing a pre-determined set of criteria. The experts gave their opinions in two iterations which were subjected to statistical analyses such as the measure of central tendency and interquartile deviation in ascertaining consensus among the experts and the Mann–Whitney U test in establishing if there is a difference in the opinions given by the experts.

The study’s findings show that six of the identified drivers of the uptake of CPS for FM were attributed to be of very high significance, while 12 were of high significance. Furthermore, it was revealed that there is no significant statistical difference in the opinions given by experts in professional practice and academia.

The study’s outcome provides the requisite insight into the propelling measures for the uptake of CPS for FM by organisations and, by extension, aiding digital transformation for effective FM delivery.

To the best of the authors’ knowledge, evidence from the literature suggests that no study has showcased the drivers of the incorporation of CPS for FM. Hence, this study fills this gap in knowledge by unravelling the significant propelling measures of the integration of CPS for FM functions.

Wind energy has developed rapidly becoming a promising source of renewable energy. Although wind energy is described as clean energy, the problem of blade disposal has emerged from decommissioned wind turbines in the renewable energy sector, these blades manufactured from composite materials are almost impossible to recycle.

This study proposed a methodological workflow for an educational approach toward accelerating the transition to a circular economy (CE) through a case study reusing wind turbine blade waste. The participants were undergraduate students. In the quantitative case study approach of students’ coursework, innovative architectural reuse was the basis of the methodology for creatively reusing blade waste. Students reused the blades as building elements.

The workflow could be beneficial to the renewable energy sector and the architecture, engineering and construction industry. The results show that the impact of creative reuse is positive as it reduces the energy consumed by conventional recycling processes, reduces carbon dioxide-equivalents and preserves the structural properties of the blades.

The research reported in this study is exploratory and findings may not be generalizable due to the location and limited number of participants in the design process. Also, the empirical data collected were limited to the views and opinions of the students and instructor.

The novel workflow provided evidence at the end of the course that participating students became more interested in CE and were able to think more independently about CE. Creative reuse promotes circularity, reducing virgin material extraction and carbon emissions.

The purpose of this paper is to introduce a web-based system that provides an efficient means for managing suppliers’ performance which also facilitates the leveraging of suppliers’ knowledge for the benefit of the on-going projects.

Case study approach is adopted. In total, 12 semi-structured interviews are conducted with Malaysia-based public listed construction companies to study their current practice and the requirements for the development of an information and communication technology (ICT) aided system for the purpose. Subsequently, a web-based system for managing suppliers’ performance is developed using ASP.net and MSSQL database.

Most of the case study companies are found to have low levels of ICT adoption and still resort to handling the majority of the tasks involved in the selection and management of suppliers’ performance manually. An ICT-based system that can improve the recording of important information about the suppliers, provide a function for supplier selection and facilitate the capture of useful reusable knowledge of the suppliers is needed.

The paper has shown empirically that a web-based suppliers’ performance management system eases the supplier selection process and the monitoring of suppliers’ performance. In addition, it demonstrates how such systems can be designed to capture and facilitate the leveraging of suppliers’ knowledge, and how suppliers’ knowledge contribution can be recognised as part of their performance. The system adopts a novel two-way communication model which provides the suppliers the access to their own performance records to identify room for improvements.

The quest for improved facilities management (FM) delivery is receiving immense focus through the incorporation of innovative technologies such as cyber-physical systems (CPS). The system’s high computational capabilities can aid in the abatement of some of the challenges plaguing FM functions. However, the requisite ingredients for the uptake of the system for FM have still not gained scholarly attention. Because performance measurement is a vital index in determining the outcome of FM methods, this study aims to investigate the influence of performance measurement indicators that are influential to the uptake of CPS for delivering FM functions.

A qualitative technique was adopted using the Delphi technique. The panel of experts for the study was selected through a well-defined process based on stipulated criteria. The experts gave their opinions in two rounds before consensus was attained on the identified performance measurement indicators, whereas methods of data analysis were measures of central tendency, inter-quartile deviation and Mann–Whitney U test.

Results from this study showed that 11 of the performance indicators were of very high significance in the determination of the uptake of CPS for FM functions, whereas 5 of the indicators were proven to be of high significance. Furthermore, there was no statistical difference in the opinions of the experts based on their affiliation with academic institutions and professional practice.

The findings of this study contribute practically by aiding policymakers, facility managers and relevant stakeholders with the vital knowledge of delivery mandates for efficient FM services that can spur the uptake of digital technologies such as CPS.

This study contributes to the body of knowledge as it unveils a roadmap of the expected performance output and its accompanying evaluation that would drive the adoption of a promising technology such as CPS in the delivery of FM tasks.

Incorporating digital technologies such cyber-physical systems (CPS) for facilities management (FM) functions is fast gaining attention. However, the rudiments for the effective espousal of such an innovative technology for the delivery of FM tasks have not received scholarly attention. In FM, the business environment is a vital component in achieving organisations’ stipulated objectives. Hence, this study aims to assess the influence of business environment factors in the adoption of CPS for FM activities.

A qualitative approach was adopted for the study using the Delphi technique. Experts were selected through a well-defined process that involved certain criteria. The opinions of the selected experts were gotten in two iterations that were subjected to analysis using statistics of measure for central tendency, and interquartile deviation to ascertain consensus among the experts, while Mann–Whitney U test was deployed in checking the difference in the views of the experts.

The results from the study indicated that eight business environment factors were of very high significance in determining the espousal of CPS for FM, while the other eight factors proved to be high significance. Also, there was no significant difference in the opinions of experts from academic institutions and professional practice.

The findings from the study would provide insight to organisations saddled with FM activities on the prevailing business environment factors that would be influential in adopting a digital technology such as CPS.

The study contributes immensely to the body of knowledge in the quest for digital transformation in FM delivery. It unveils the significant business environment factors that are influential in the drive for incorporating new innovations such as CPS for FM functions.

The South African construction industry (SACI) is a huge employer of labour as the industry depends mostly on human resources to carry out its activities. However, the industry has also been noted for its poor workforce management and lack of attention to human resource management (HRM) issues. Therefore, this study aims to assess the challenges facing the effective management of the construction workforce in South Africa with a view to improving HRM activities in the industry and improve overall service delivery through an effectively managed workforce.

A pragmatic philosophical view using a mixed-method research design was adopted. The study’s qualitative strand was achieved through a Delphi, whilst the quantitative strand was achieved through a questionnaire survey. In addition, descriptive and inferential statistics such as mean item score, Kruskal-Wallis H-test, exploratory and confirmatory factor analysis were adopted for data analysis.

With high reliability, construct validity and model fit indices, the study found that for effective HRM to be attained within construction organisations, careful attention must be given to issues surrounding the nature of the industry, unhealthy working environment, employee-related issues, diversity and working condition in the industry.

Whilst several studies have been conducted on HRM, there is a lack of studies on the major challenges facing effective HRM in the SACI. The findings also offer future research studies a good theoretical platform to build upon.

This paper aims to present a review of research developments relating to the application of building information modeling (BIM) to facilities management (FM). It sheds light on major technical and organizational issues with the view of identifying how existing BIM for FM knowledge applies to large capital projects.

The study adopted a literature search approach to retrieve relevant articles which were subjected to keyword analysis to enable categorization of extant BIM for FM research into appropriate sub-domains. A qualitative analysis of 94 BIM for FM-related literature was carried out in addition to a review of 9 capital project-related articles, leading to the establishment of research trends, gaps and future directions.

The review found that research in the BIM-FM integration field is predominantly technology and process-oriented, with less attention paid to people or organizational aspects. Therefore, there is a need for expanding the knowledge base in this direction. Several future research directions were identified to lay the foundations for research on BIM application to FM in large capital projects and other application areas for interested researchers. These future directions were categorized under the identified sub-domains of the field and mapped onto two generic activities, i.e. technical integration and business integration, involved in technology adoption by organizations.

The main contribution of this study is the categorization of existing research on BIM for FM, leading to the identification of research gaps concerning the initiation and implementation of BIM for FM in large capital projects. As a secondary benefit, this study has validated some sub-domains of the BIM for the FM research field identified in previous review papers using an empirical approach. This validation of defined sub-domains is useful for an emerging research field as it provides a common understanding of trends and specific application areas.
