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.

The occurrence of fire accidents in hospital buildings has become a serious challenge and more serious in developing nations. The purpose of this paper intends to assess fire safety measures in Nigerian hospital facilities. The significance of this study is to ensure that the design and construction of hospital facilities enhance the safety of users and properties.

The data were collected via a case study and questionnaire survey and administered to the facility users. The study survey is to assess the respondents' perception of fire safety measures in hospital facilities and suggest possible policy measures that will be employed to enhance safety.

This paper found that 91% of the respondents have awareness of fire safety measures in hospital facilities. Electrical faults and combustible materials were identified as the frequent causes of fire occurrences in hospital facilities. This can be averted where flammable materials and electrical appliances are correctly installed, and safety rules enforced. Findings show that safety rules are lax in public than standard private hospitals.

This paper is limited to fire safety measures in Nigerian healthcare facilities. Future research is needed to evaluate the level of compliance from design, construction and post-construction of precautionary fire safety measures in hospital facilities in Nigeria.

This paper recommended that designers and hospital administrators should improve on fire safety measures via the development of fire safety management plan and education. Thus, enforcement of fire safety measures in hospital facilities as specified in building codes should be implemented and monitored during and after the design of the hospital buildings. Findings provide valuable lessons on how to improve the fire safety measures in healthcare facilities across the states and other developing countries with similar healthcare situations.

This paper demonstrates that the stakeholders, especially government agencies concern with approval and enforcement of fire safety measures in healthcare facilities need to reawaken to her responsibility because of the lax implementation across the states.

The high consumption of energy by buildings may have enhanced land degradation, flooding, air pollution and many other hazardous environmental issues. However, green practices in buildings have been proved as one of the successful technologies to mitigate these issues. Past studies have shown lax green practices in Nigerian buildings. Concerning public hospital buildings, this is yet to be explored. Therefore, this paper aims to investigate the barriers to green practices and proffer possible policy solutions to promote hospital green buildings.

In attaining these objectives, the view of hospital building contractors, design team, hospital management and policymakers in the relevant ministries/agencies was engaged via virtual interviews. The collated data were analysed and presented in the thematic pattern.

Findings show that green building construction is extremely low in Nigeria, but the worst hit is the health-care buildings across the states. Government/policy-related, organisational/leadership-related, financial-related, technical-related, design team-related and stakeholders’ behaviour-related barriers emerged as the main six themes of barriers affecting public hospital green buildings implementation initiatives. Findings show that proffering possible policies to addressing these barriers may improve public hospital green construction across the states.

This paper is limited to barriers to green buildings implementation in public hospitals in Nigeria, and data collection was through virtual interviews but does not affect the strength of the findings. Thus, this paper suggests that the sub-themes and variables/items that emerged from the collated data as presented in Figure 1 can be further developed quantitatively via questionnaire survey to validate and improve the reliability of results from this paper.

As part of this study’s implications, suggestions from this paper will stir up policymakers’ decisions, to be tailored towards achieving green buildings implementation initiatives in Nigerian public hospitals.

To the best of the authors’ knowledge, this paper is probably the first that attempted to investigate the barriers to green buildings implementation in public hospitals in Nigeria.

Several studies have shown that climate change is a threat to sustainable human living and high consumption of energy by buildings is a contributory factor. However, green practices in buildings have been proved as one of the successful technologies to mitigate global warming. Previous studies have shown lax green practices in developing countries’ buildings, but how far concerning green certification of buildings in Nigeria is yet to be explored. Therefore, this paper investigated the barriers to green certification of buildings (GCB). Also, the paper proposed a model for promoting GCB in Nigeria.

Eighteen experts with green building certification knowledge were engaged across three of Nigeria’s cities (Benin City, Abuja and Lagos) via scheduled WhatsApp video and teams calls. Collated interview data were analysed and presented in themes.

Findings show that there is an absence of a framework to promote GCB in Nigeria. Hence, GCB is low across the states. Twelve main sub-themes emerged as the barriers to GCB in Nigeria. Also, eight key sub-themes emerged as the possible concepts that can be used to improve GCB in Nigeria and formulated into a proposed framework to promote GCB in Nigeria.

This paper is limited to GCB in Nigeria and only 18 participants were engaged. Thus, this paper suggests that a mixed-methods approach should be conducted in future studies with wider coverage. This may assist to validate the paper’s findings.

Findings from this paper will stir up practitioners in green building and influence the promotion of GCB in the sector. As part of this study’s implications, suggestions through the paper’s proposed framework will benefit Nigeria’s policymakers to make decisions towards achieving GCB. This can be achieved via the proposed framework to promote the concept across Nigeria.

This paper is probably the first that attempted to investigate the barriers and proffer policy solutions via a framework to promote GCB in Nigeria and by extension in other developing countries.

The adoption of nature-based solutions (NBS) for resilient cities has been receiving concern because of global threats of climate variation and a bid to achieve the Sustainable Development Goals 2030. NBS promotes a healthy environment and discourages land loss. NBS applications have been researched, especially in developing nations; however, there is a lack of evidence on their roles, impediments and drivers in southern Nigerian cities. Therefore, this study aims to systematically review the applicability of NBS for resilient urban residences (RUR) in southern Nigeria. Also, it proposes strategies for addressing environmental issues via a framework that will support future studies.

Southern Nigeria's riparian settlements are vulnerable to climate variability's devastating effects. A systematic review of literature on NBS for RUR resilience was conducted, sourcing 29 papers included in the study from 2004 to 2023 using Preferred Reporting Items for Systematic Reviews and Meta-Analyses from Google Scholar, Scopus and Web of Science databases in November 2023.

The review identified three themes: NBS's role in fostering urban resilience, impediments to its application and drivers for resilient RUR, with five roles, eight impediments and eight drivers identified in the literature.

This study explores literature on environmental drivers for practitioners promoting NBS, suggesting a qualitative research approach for advanced studies. However, the systematic review-based recommendations maintain the robustness of the NBS application for RUR in southern Nigeria, despite the need for advanced studies.

This study outlines the five roles, eight impediments and eight drivers for promoting the application of NBS in southern Nigeria. This study noted that NBS can improve urban residential precincts, maintain residents' quality of life, purify air, regulate temperature and reduce glare, urban heat and land loss. The findings can be used by environmental and construction practitioners, clients, academics and policymakers to promote NBS applications in Nigeria. Adapting NBS should be a basic consideration in residential property planning and design for building plan approval.

To the best of the authors’ knowledge, this systematic review analysis is the first to explore NBS application in Southern Nigeria RUR, offering flexible strategies to advance NBS in the Nigerian locale.

The frequent occurrence of hazards, especially on junior staff in developing countries, is a major setback on project delivery. This is because the safety of the construction workers' environment influences their performance. Although a range of literature has addressed safety measures on construction sites, how far is their compliance with personal protective equipment (PPE) on junior staff is yet to receive in-depth studies in Nigeria. Therefore, this study investigated the level of Nigerian construction companies' compliance and proffered possible solutions that intend to improve the implementation of PPE on junior staff.

The data were collected via observation and face-to-face interviews among the selected companies' staff in Lagos and Abuja. The interview is to determine their perceptions regarding compliance with PPE on construction sites.

Findings show that compliance with PPE on junior staff, especially the indigenous construction companies, is poor. This is because monitoring and enforcement are lax by government regulatory agencies. Also, findings show that many international construction companies ensure that junior workers obey site safety measures those mitigate the chance of hazard occurrence during construction as a policy.

This paper data collection is limited to Abuja and Lagos, and a phenomenology type of qualitative research was employed, but this does not weaken the robustness. Future research is needed to consider adopting a mixed-methods approach.

As part of this paper's implications, findings recommended that the construction company's safety regulations and policies should be robust and enriched to mitigate site-related hazards via a framework or mechanism, but the government agencies/ministries need to give the enabling direction, strict monitoring and enforcement of PPE on junior staff. This paper intends to stir up the appropriate government authorities for possibly passing the Labour, Safety, Health and Welfare Bill 2012 (updated in 2016) Act into law.

This study demonstrates that the government agencies concern with approval and enforcement of construction site safety needs to reawaken to their responsibilities because of the lax implementation in many sites, especially in indigenous construction sites.
