Several studies have shown that the mechanism of labour-intensive construction (LIC) projects can mitigate high unemployment and create skilled development, especially in developing nations. The guidelines and practices for implementation may have faced some encumbrances in some countries. Whether the current guidelines and practices for municipal infrastructure support agent (MISA) to execute LIC projects face hindrances in South Africa has yet to receive in-depth studies. Thus, this study attempts to proffer policy solutions to improve the proposed revised guidelines and practices for MISA in LIC project execution in South Africa.

The study's objectives were accomplished via a combination of 16 virtual interviews of built environment professionals and government officials involved in LIC project execution in South Africa and supported by the analysed documents. A thematic approach was used to analyse the data and presented two main themes.

Findings show lax enforcement of discretionary funds, lax institutional capacity and inadequate individual skills, among others, as the gaps in existing South Africa's LIC guidelines and practices. Also, policy solutions to address the gaps were proffered.

The suggested feasible policies will improve the proposed revised guidelines and practices for MISA in LIC project execution in South Africa. This guide will promote the development of individual skills, institutional capacities and increase employment across South Africa.

This study promotes the use of LIC to create employment and contribute to proffering measures that will improve the proposed revised third edition of the guidelines and practices for MISA to execute LIC.

In the past, the construction sector faced a low technological development level. Recently, studies have shown that the fourth industrial revolution (4IR) technologies play a significant role in construction project performance. But how prepared are the developing countries’ construction consultants, a focus in Nigeria, in embracing the 4IR technologies in construction administration is yet to receive in-depth research. Thus, this paper aims to examine how Nigerian construction consultants are prepared to embrace 4IR technologies in pre- and post-construction activities.

To evaluate the perceptions of construction consultants, the study conducted a virtual interview. The participants were asked the following key questions: What technologies that are currently linked with the 4IR and used by construction consultants in the industry? What factors may hinder the strategic application of 4IR by the construction consultants? What initiatives may be necessary to overcome the perceived encumbrances faced by the construction consultants? Twelve semi-structured interviews from selected construction consultants were engaged and collated data analysed via a thematic approach.

The paper identifies digital software used by construction consultants that have a link with 4IR technologies. From the ten emerged hindrances, cost of adopting the technologies, unwillingness on the part of stakeholders to adopt, inadequate standards and reference architectures and absence of awareness were ranked high as the factors hindering construction consultants from using 4IR technologies. Initiatives that can overcome the perceived encumbrances are examined in detail.

This study is restricted to construction consultants in Nigeria, and only 12 participants were engaged, but these do not affect the strength of the results. Thus, this study recommends a mixed-methods approach for future research with broader coverage.

The Government should intervene via subsidy regime and overhaul the academic curriculum to reflect the current trend of practices regarding technologies. Also, there should be vigorous enlightenment and pragmatic sensitisation of construction stakeholders and knowledge training of practitioners, among others, were suggested. As part of this paper’s implications, a perception-based model was developed to promote 4IR technologies for construction consultants in the Nigerian construction sector. This model encourages the construction consultants to embrace 4IR technologies for better service delivery, project performance and client satisfaction.

This paper appraised 4IR technologies’ role in the construction sector, focusing on the preparedness of the construction consultants in Nigeria. Also, the study identified the issues and proffer initiatives to improve 4IR usage by construction consultants.

Procurement management in infrastructure development has gained considerable attention in developing countries. It is because of the success in the developed nations. Studies have shown that Nigeria's infrastructure development needs far exceed its current provision. Also, studies are scarce to reveal whether procurement management has been successful in infrastructure development projects in Nigeria. Therefore, this paper investigated the root cause of the perceived encumbrances impeding procurement management in infrastructure development projects and proffered policy measures to improve future Nigeria's infrastructure development.

Data were collected via unexplored exploratory virtual interviews and selected cases from secondary sources. The engaged construction and engineering consultants have been involved in the procurement management of infrastructure projects in Nigeria. Thematic analysis was adopted to analyse the collected data.

The root causes of the pitfalls that emerged from the study include lack of competition and transparency, embezzlement and mismanagement of public funds, snail speed bureaucracy and bottleneck and lack of skills and knowledge. Others are collusion/bid-rigging/price-fixing/cartel formation, corruption, lack of professionalism, unbridled politicking, embezzlement and mismanagement of public funds, incompetence of tender boards, lack of patriotism to national service and lack of government organisations’ procurement capacity.

This paper is restricted to unravelling the encumbrances in procurement management of Nigeria's infrastructure development projects. Future research is desirable to adopt a quantitative approach for more extensive coverage and validate findings from this paper.

The paper findings, including those learnt from each case study evaluated, would undoubtedly influence policymakers and construction and engineering practitioners on the key strategies to employ in implementing future procurement management in Nigeria's infrastructure development projects.

This paper would assist policymakers and other stakeholders desirous of improved infrastructure to focus their priorities in mitigating the identified root cause hindering procurement management in Nigeria's infrastructure management.

Funding infrastructural facilities of higher institutions, especially in some developing nations such as Nigeria, that is under-funded, is a challenge in the current era. Private organisations participation in infrastructure development via a proposed expanded corporate social responsibility (ECSR) may enhance infrastructural facilities provision. There is a paucity of literature regarding ECSR, a form of infrastructure tax relief providing infrastructural facilities for higher institutions. Therefore, the study investigated the role of private organisations via a proposed ECSR in the provision of infrastructure and proffer ways to enhance higher institutions' infrastructure development delivery in Nigeria.

The study data were collated via face-to-face interviews and observation of existing buildings. From the six geo-political zones, two higher institutions each were selected for a good representation across Nigeria. Saturation was achieved with 26 participants interviewed. The emerged three main themes were analysed via thematic analysis.

Findings show inadequate infrastructure development in Nigerian higher institutions. Lack of policy and institutional framework, lax governance, level of transparency, and corruption, emerged as the key issues that may hinder private organisations from participating in public higher institutions infrastructure development delivery in Nigeria via ECSR. Others are lack of autonomy, inadequate planning, high level of impunity, political affiliation, poor management, and access to funding. The study proffers some recommendations based on these findings.

This research is restricted to the role of private organisations via ECSR in infrastructure development (buildings) in Nigeria's public higher institutions. Future study is needed to validate the proposed ECSR framework in developing countries for the provision of buildings for higher institutions in their host communities.

The paper will advance the philosophy of corporate social responsibility to the provision of building facilities in host communities' higher institutions by private companies through tax relief and supported by a proposed Presidential Executive Order.

The proposed ECSR framework can be used to improve building facilities in Nigeria's higher institutions. This may assist and stir up policymakers to explore the proposed model and back up with an established policy such as infrastructure tax relief (ITR) for implementation.

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.
