An increase in outsourcing of consultancy services has been observed during procurement and delivery of public-sector infrastructure projects. However, the incidence of project failure has continued unabated despite this shift by public-sector entities. Also, there appears to be limited literature focussed on seeking to provide the rationale governing the decision to outsource or insource consultancy services by public-sector organisations. The purpose of this study was to appraise the performance of public-sector projects in which consultancy services have been outsourced or insourced. These are the gaps which this study was undertaken to fill.

A grounded theory methodology (GTM) research design was adopted based on the nature of evidence sought and gathered from a Provincial Department of Public Works and Infrastructure (PDPWI) in South Africa. Data was obtained from a mixture of semi-structured interviews and project-specific documents spanning a five-year period and was analysed according to the procedures associated with GTM. Accordingly, open coding, axial coding and pattern matching were carried out at several intervals to develop categories and themes.

The findings of the study showed the absence of a structured approach within the PDPWI for facilitating decisions pertaining to outsourcing or insourcing consultancy services within construction projects. Furthermore, the study established that both approaches yielded similar results across all performance facets of cost, time and quality. In addition, a detailed insight into the steps required for the successful application of GTM in built environment research has been provided in the study.

Limited studies have been undertaken to compare the impact of either outsourced or insourced services on the organisational and project performance. This was the gap to which the study reported in this paper was undertaken to contribute.

Facilities management (FM) plays a key role in the performance of businesses to ensure the comfort of users and the sustainable use of natural resources over operation and maintenance. Nevertheless, reactive maintenance (RM) services are characterised by delays, waste and difficulties in prioritising services and identifying the root causes of failures; this is mostly caused by inefficient asset information and communication management. While linking building information modelling and the Internet of Things through a digital twin has demonstrated potential for improving FM practices, there is a lack of evidence regarding the process requirements involved in their implementation. This paper aims to address this challenge, as it is the first to statistically characterise RM services and processes to identify the most critical RM problems and scenarios for digital twin implementation. The statistical data analytics approach also constitutes a novel practical approach for a holistic analysis of RM occurrences.

The research strategy was based on multiple case studies, which adopted university campuses as objects for investigation. A detailed literature review of work to date and documental analysis assisted in generating data on the FM sector and RM services, where qualitative and statistical analyses were applied to approximately 300,000 individual work requests.

The work provides substantial evidence of a series of patterns across both cases that were not evidenced prior to this study: a concentration of requests within main campuses; a balanced distribution of requests per building, mechanical and electrical service categories; a predominance of low priority level services; a low rate of compliance in attending priority services; a cumulative impact on the overall picture of five problem subcategories (i.e. Building-Door, Mechanical-Plumbing, Electrical-Lighting, Mechanical-Heat/Cool/Ventilation and Electrical-Power); a predominance of problems in student accommodation facilities, circulations and offices; and a concentration of requests related to unlisted buildings. These new patterns form the basis for business cases where maintenance services and FM sectors can benefit from digital twins. It also provides a new methodological approach for assessing the impact of RM on businesses.

The findings provide new insights for owners and FM staff in determining the criticality of RM services, justifying investments and planning the digital transformation of services for a smarter provision.

This study represents a unique approach to FM and provides detailed evidence to identify novel RM patterns of critical service provision and activities within organisations for efficient digitalised data management over a building’s lifecycle.

Despite the widespread study and application of public-private partnerships (PPPs) since the 1980s, the field lacks a universally accepted definition that captures the concept's complexity. This study aims to offer a definition and foster a more substantive and comprehensive discourse on PPPs to improve communication and understanding between academics and practitioners from diverse disciplines and legislative backgrounds.

Grounded in the family-resemblance concept proposed by German philosopher Ludwig Wittgenstein, this study conducts a comprehensive literature review to identify core and non-core elements frequently cited in PPP descriptions. The authors used these findings to develop the PPP sunflower model as a structured framework for defining PPPs.

The analysis elucidates six core elements consistently present in PPP descriptions: clarity of roles and responsibilities, appropriate risk allocation and sharing, injection of expertise and resources, cooperation and teamwork, a bundle of services, and long-term contracts. Coupled with identified non-core elements, these core components comprise the PPP sunflower model, a structured framework for defining PPPs that accommodates their multi-faceted nature.

The PPP sunflower model distinguishes itself as a unique contribution to the PPP literature. It offers a rigorous theoretical framework that can elucidate the complexity of PPPs for various stakeholders. The model serves as a practical tool for evaluating the authenticity and viability of PPP projects. The study's novelty lies in its adoption of the family-resemblance concept, thereby providing a comprehensive, multi-dimensional framework that enhances the understanding of PPPs across different disciplines and legislative contexts.

The purpose of this paper is to help better understand the translation process of the management control system (MCS) of privatised solid waste management (SWM) towards creating a stable network.

Drawing on the actor network theory (ANT), the case of a privatised SWM was studied. Data were collected from all entities involved in the privatisation process of SWM, which include Department A, Corporation X and the private sector concessionaire. Six documents were reviewed, 20 interviews were conducted and two observations were carried out.

The findings reveal that the control mechanism of SWM is complex, involving the interaction between human and non-human actors. Non-human actors include the key performance indicators (KPIs) and the concessionaire agreement (CA), which are the main control mechanisms towards creating a stable SWM network. Essentially, stability is achieved when the KPIs and CA can influence the activities of both intra- and inter-organisational relationships.

This paper provides a better understanding of the translation process of the MCS that adds to the stability of the network of a privatised SWM from the lens of the ANT.

This study aims to improve a construction company's overall project delivery by utilising lean six sigma (LSS) methods combined with building information modelling (BIM) to design, modularise and manufacture various building elements in a controlled factory environment off-site.

A case study in a construction company utilised lean six sigma (LSS) methodology and BIM to identify non-value add waste in the construction process and improve sustainability.

An Irish-based construction company manufacturing modular pipe racks for the pharmaceutical industry utilised LSS to optimise and standardise their off-site manufacturing (OSM) partners process and leverage BIM to design skids which could be manufactured offsite and transported easily with minimal on-site installation and rework required. Productivity was improved, waste was reduced, less energy was consumed, defects were reduced and the project schedule for completion was reduced.

The case study was carried out on one construction company and one construction product type. Further case studies would ensure more generalisability. However, the implementation was tested on a modular construction company, and the methods used indicate that the generic framework could be applied and customized to any offsite company.

This is one of the few studies on implementing offsite manufacturing (OSM) utilising LSS and BIM in an Irish construction company. The detailed quantitative benefits and cost savings calculations presented as well as the use of the LSM methods and BIM in designing an OSM process can be leveraged by other construction organisations to understand the benefits of OSM. This study can help demonstrate how LSS and BIM can aid the construction industry to be more environmentally friendly.

Studies showed that stakeholders want the construction sector’s organisations to be more accountable and transparent regarding social and environmental issues through corporate social responsibility (CSR). There is a paucity of literature regarding CSR implementation in the construction sector, especially in developing countries like South Africa. Hence, the study evaluated CSR’s merits and hindrances and suggested solutions to enhance its implementation in the South African construction sector of Mpumalanga Province.

The researchers employed a questionnaire survey method to collect data from 68 useable respondents in the South African construction sector of Mpumalanga Province. The main section of the questionnaire was divided into three parts, each addressing an objective mean item score ranking technique.

Findings show management lacks willingness, absence of recognition for implementing CSR at tender adjudication, professionals regard CSR as a “soft issue,” inadequate ability to carry out CSR initiatives and lax CSR knowledge emerged as the key issues hindering construction stakeholders, especially construction companies, from participating in CSR in South Africa. The research suggests initiatives to enhance CSR in the construction industry.

The study shows that the findings can be used to improve the implementation of CSR engagement and possibly enhance a policy to stimulate friendly CSR in the South African construction sector.

The purpose of this study is to explore the comparative effects of mainstream celebrities and social media influencers on consumer advocacy and relationship intentions. The study also examines the direct and serial mediation effects on those relationships.

The survey questionnaire was used to collect data from 718 respondents throughout Malaysia, with convenience and snowball sampling techniques employed. The data were analyzed based on the structural equation modeling (SEM) approach through the AMOS version 24. The PROCESS MACRO v-4.20 was applied to evaluate mediating effects in the model.

The results reveal that celebrity endorsers' involvement in social media significantly influences the uses of social media, which also impacts the attitudes and, subsequently, consumer relationship and advocacy intentions. The study found that mainstream celebrities and social media influencers effectively promote brands, and it discovered insignificant differences in their effects on the analyzed relationships.

This study has been conducted on consumers in Malaysia; it may have different effects on consumers in other countries.

Brand managers and policymakers may benefit from following the study's guidelines for making consumer relationship and advocacy intentions by celebrity endorsers and uses of social media.

The brand community can benefit from tightening their social bondage by sharing and managing crucial information from celebrities and using social media.

The study explores the effects of mainstream celebrities on consumer relationship and advocacy intentions using social media networks and managing consumer attitudes.

This study explores the role of organisational culture in promoting collective coping strategies in construction project teams in the United Arab Emirates (UAE). Three collective coping strategies were examined, including problem-focused, relationship-focused and emotion-focused coping strategies.

O'Reilly et al.’s (1991) organisational culture profile (OCP) assessed organisational culture values. Data were collected through an online questionnaire from practitioners in the United Arab Emirates (UAE) construction organisations.

The findings show a high correlation between competitiveness culture values and problem-focused team coping strategy. Relationship-focused team coping strategy was found to have a high correlation with emphasis on rewards and performance orientation values. Conversely, an emotion-focused team coping strategy correlates highly with competitiveness, supportiveness and emphasis on rewards cultural values.

The cross-sectional design of the survey and the UAE context may present limits to the generalisability of findings.

Limited attempts have been made to study collective coping in construction project teams. The study paves the path for exploring emergent socio-psychological concepts in construction organisations, including the impact of organisational culture on team collective coping with adverse events.

Understanding the pivotal impact of culture on successful team coping provides managers with valuable insights into managing situational adversity in construction project teams.

While the causes of migration across a range of diverse societies have been studied in the extant literature, a systematic study encapsulating the extant literature pertaining to the push and pull factors for the phenomenon of migration has not been conducted so far. The purpose of this study is to present a gist of the push and pull factors that are responsible for migration patterns across different contexts.

Inferences from the literature review and documentary analysis show that, on the one hand, the push factors for migration entail the enforced reasons like natural causes, wars, health and the like; the pull factors are, by and large, the affirmative ones related to better job opportunities, anticipation of improved well-being, etc.

It may also be deduced that both the categories of migration causes are analyzed at the individual, group, societal as well as regional levels.

Hitherto, the migration research has focused on understanding the antecedents and consequences of migration in temporal–spatial context, but a syncretic understanding of the push and pull factors behind migration vis-à-vis smart cities is required. The present study seeks to fill this gap. Besides contributing toward the mainstream literature on migration in general, the present study also adds to the literature pertaining to the specific factors responsible for migration patterns.

The purpose of this study is to conduct a systematic review on encumbrances facing the implementation of GBP in selected African countries. Green building practices (GBP) implementation is germane and promotes the development of a green environment and buildings. Many studies have been conducted on the encumbrances faced with GBP implementation, especially in developing countries. But evidence of a comprehensive study that investigates and analyses these hindrances from different developing countries is missing. Therefore, a systematic review is conducted systematically reviewing the current literature on encumbrances facing the implementation of GBP in selected African countries. Also, the study proffers possible drivers for stakeholders to promote GBP in African countries.

A total of 38 published papers were identified from the Web of Science, Scopus database and supported with materials from Google Scholar related to Africa’s GBP. The continent was divided into five regions, and each region covered three countries.

Two themes emerged from the analysed review – encumbrances facing GBP implementation and possible drivers for stakeholders to promote GBP in African countries. A total of 18 encumbrances and 18 drivers were identified from the analysed literature and grouped into 6 sub-themes.

Current empirical articles were reviewed to suggest the drivers for stakeholders to promote GBP that emerged from this paper. Thus, to enrich the results from this paper, primary source data of regional studies of GBP in Africa’s context should be carried out via the mixed-methods design.

A total of 18 drivers were identified for stakeholders to promote GBP in Africa and form part of the paper’s implications. Also, the paper findings would serve as a treasured suggestion for the stakeholders (policymakers, construction practitioners, clients and academics) who are fascinated by the promotion of GBP across African nations.

This is possibly the foremost analysed systematic review study on GBP implementation in Africa. Therefore, it fills the theoretical gap and proffers possible drivers for stakeholders to promote GBP in the African context.
