Considering the need for standard and cost-effective housing delivery in South Africa, this study aims to make a case for three-dimensional (3D) printing in housing delivery through an assessment of the inherent benefits and the factors that could acts as barriers to its adoption.

The study used a survey of construction professionals currently actively involved in a construction project in the country. Analysis of data gathered was done using a four-step analysis approach and relevant descriptive and inferential statistics were adopted.

The study revealed through factor analysis that 3D printing in housing delivery promises better cost delivery, increased productivity and stakeholder satisfaction, socio-economic benefits, improved quality and faster housing delivery. While these benefits exist, factors such as technical and operational issues of the 3D printing itself, organizational and personnel issues as well as lack of awareness of the inherent benefits and understanding of the technology among stakeholders can prove to be barriers to the adoption of the technology.

In the quest to achieve standard and affordable housing which is part of its National Development Plan 2030, the government can adopt 3D printing which promises significant benefits in terms of cost, time, quality, productivity and stakeholders’ satisfaction. Property developers can also adopt the technology to improve their housing delivery, competitive advantage and the economic value of their properties.

The study contributes significantly to the body of knowledge as it reveals the benefits and barriers of adopting 3D printing in housing delivery in South Africa – an aspect that has not gained significant attention in the fourth industrial revolution and housing delivery discuss in the country.

The purpose of this paper is to give an insight into lessons learned so far on the in situ upgrading and eradication of informal settlements in South Africa. This is with a view to accessing progress made to date, the line of focus and to ascertain whether in situ upgrading or eradication of informal settlement is the best option in solving the problem of informal settlement integration into the large society.

The research is conducted with reference to existing theoretical literature, published and unpublished South Africa research. The study is mainly a literature survey/review and looks at challenges that have been overcome to bring about the success made to date, thus striving to achieve the goals and objectives of a city without slums. The research ties up the identified challenges with recommendations to the problems to enhance the reality of having a city without slums.

One of the primary findings that emanated from the study revealed that all development where people have to be displaced or inconvenienced has come with problems. Other findings attribute the little success achieved to date to the in situ upgrading of the existing settlement and the eradication of the settlement. Though policy activated has not been well implemented for the betterment of all, progress has been made nonetheless.

The upgrading and eradication of informal settlement have long been a subject of global discussion, which has taken firmer root since it was declared to be one of the Millennium Development Goals agenda. The paper contributes to this body of knowledge.

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.

The idea of implementing supply chain management (SCM) principles for the construction industry was embraced by construction stakeholders to enhance the sector's performance. The analysis from the literature revealed that the implementation of SCM in the construction industry enhances the industry's value in terms of cost-saving, time savings, material management, risk management and others. The construction supply chain (CSC) can be managed using the pull or push system. This chapter also discusses the origin and proliferation of SCM into the construction industry. The chapter revealed that the concept of SCM has passed through five different eras: the creation era, the use of ERP, globalisation stage, specialisation stage and electronic stage. The findings from the literature revealed that we are presently in the fourth industrial revolution (4IR) era. At this stage, the SCM witnesses the adoption of technologies and principles driven by the 4IR. This chapter also revealed that the practice of SCM in the construction industry is centred around integration, collaboration, communication and the structure of the supply chain (SC). The forms and challenges hindering the adoption of these practices were also discussed extensively in this chapter.

This chapter aimed to uncover the gaps in the existing construction supply chain management (CSCM) models. Organisational culture and the fourth industrial revolution (4IR) components are the two gaps that were identified through reviewing existing CSCM models. The 4IR is driven by three components which are smart management, virtualisation and cyber-physical system. It was proposed in this chapter that the practice of CSCM should be in tandem with the components of 4IR. This chapter recommended that for the effective practice of the construction supply chain (CSC) in the 4IR era, construction stakeholders should adopt an innovative and collaborative organisational culture. The organisational culture adopted by a construction firm performs a crucial role in encouraging construction stakeholders in adopting 4IR components for CSCM. Each of the 4IR components is driven by technologies like autonomous robots, building information modelling (BIM), radio frequency identification (RFID), the internet of things (IoT) and others. Among all the technologies, it was discovered that RFID and BIM had gained prominence in most CSC literature. The chapter recommended that blockchain, digital twins and the cyber-physical system are the next trending technology for CSCM.

This chapter presented the model for the effective practice of construction supply chain management (CSCM) in the fourth industrial revolution (4IR) era. The model was developed after discovering that the failure of adopting the 4IR component has hindered the synchronisation of construction supply chain (CSC) activities. While some stakeholders are willing to manage their CSC under the 4IR era, most have no clue how to go about it. Most stakeholders are familiar with an existing practice built around collaboration, integration, supply chain structure and trust. This chapter bridges the gap by introducing organisational culture and 4IR components for modelling the CSCM in the 4IR era. The model was backed and grounded with a robust theoretical framework. The theories include social identity theory, change theory and resource-based view theory. It was discovered that the organisational culture adopted by construction stakeholders determines their willingness to embrace the 4IR component for the management of CSC. The 4IR components were divided into smart management, virtualisation and cyber-physical systems. The chapter recommended that the practice of SCM in the Nigerian construction industry should be modelled around the six constructs that were used in developing the model for this study.

The construction industry's application of supply chain management (SCM) principles is confronted with numerous Gordian Knots ranging from late delivery, fragmentation and others. The challenges could be attributed to multiple factors. The most crucial amongst them are adopting management ideas rooted in the second and third industrial revolution without taking consideration of the present industrial revolution. Evidence from literature and practice revealed that we are presently in the fourth industrial revolution (4IR). This chapter calls for developing a model that supports construction supply chain management (CSCM) in tandem with the principles of 4IR. This chapter presents the idea behind the conception, development and benefit of this research book to construction stakeholders and academia. The various shortcomings in the existing model for CSCM were also discussed in this chapter extensively.
