A conceptualised model LIP+3C is also presented as the outcome of the review Design/methodology/approach: Literature review focused on exploring the conceptual definitions of H&S culture was conducted. A matrix for the identified literature was developed to identify common H&S culture elements. Findings It was revealed that there is still confusion and lack of consensus on the concept of H&S culture. However, the H&S culture elements of leadership, involvement, procedures, communication, competence and commitment dominate the literature. Research limitations/implications: Literature review was conducted on 15 published peer reviewed journal articles. The validation of the elements found in the study is currently under way although preliminary results confirm the findings. Practical implications: H&S culture has been identified as being of great importance to H&S performance improvement. Identifying culture elements that can easily be implemented and understood will contribute to improving the current H&S status. Originality/value: Adopting the LIP+3C culture model composed of elements that can easily be implemented and understood will contribute to improving the current H&S status for the construction industry

Design' Methodology 'approach Structured interviews were conducted with project managers from two major public client organisations in order to explore clients' commitment to H&S, allocation of resources in terms of H&S, and whether clients were leading by example on H&S. Findings The pilot study found that prima facie the H&S safety culture of the two public clients was not strong when compared against the expected elements of a good H&S culture. Limitations The survey was only conducted in two major public clients and interviews were only conducted with senior project managers and so the results may not be generalised to all public clients in Botswana. Further, only a few selected elements of the many suggested characteristics of H&S culture were assessed in the study. Originality' value of this paper The H&S culture of construction clients or owners has not been extensively explored even though it is widely accepted that the client is very important to H&S performance improvement. The paper contributes to this body of knowledge.

To succinctly account for biases in the fixed effects (FE) model, the authors adopted different bias-corrected techniques. The majority of these techniques provided evidence that PPP investments in energy are boosted by increasing the desire for accountability, prioritising the voice of the masses and disabusing the rule of laws. This study could not find any positive influence from the control of corruption to PPP investment in energy. Design/methodology/approach-The acute shortage of power supply in SSA has attracted PPP investments in the energy subsector of the economy, leading to the recent debate on governance and public, private investment. The authors contributed to this argument by examining the impact of country governance on PPP investment in energy using a sample of countries in SSA. Findings-Therefore, the authors concluded that low control of corruption is responsible for the inadequate volume of PPP investments. In the light of this, the government should redefine the anti-corruption bill of their sovereignty to accommodate severe sanctions when necessary. Originality/value-This paper uses the fixed effects (FE) model by introducing batteries of nonlinear panel models to capture the relationship between the impacts of country governance on PPP investment in energy.

The continued poor state of construction H&S and the inability of designers and contractors to influence an industry-wide H&S culture change motivated the article. It was also recognised that one of the reasons the construction industry continued to lag in H&S performance was the way in which H&S implementation and management was organised. The article proposes a client-centred model for H&S performance improvement. The conceptual model and its factors were developed from both literature and a Delphi survey. Structural equation modelling was applied to data collected from a questionnaire survey to design a best fit model. The key finding was that, generally, client H&S culture impacted on project H&S performance. The influence of clients was found to be statistically significant when commitment, communication and H&S procedures were evident. This finding was encouraging as it specifically shows how clients could influence performance. However, it remains to be seen whether these results could be replicated in other datasets. If indeed that is the case, then this article contributes significantly to the body of knowledge.

To better understand this underexplored area, this study uses a four-stage review approach utilising a scientometric and systematic analysis method based on 112 articles. Using statistical analysis to evaluate the relationship between research components, the study reveals strong associations between components of research methods, data sources and analytical techniques. Researchers are also increasingly looking to mixed paradigms in data sources and designs, highlighting a methodological plurality in construction robotics research. Implications on what this means...

The lack of a common definition and methodology has led to inconsistency and confusion across disciplines. This review aims to clarify the most existing geopolymer definitions and the diverse procedures on geopolymer methodologies to attain a good understanding of both the unary and binary geopolymer systems. This review puts into perspective the most crucial facets to facilitate the sustainable development and adoption of geopolymer design standards. A systematic review protocol was developed based on the Preferred Reporting of Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist and applied to the Scopus database to retrieve ar...

As a result, few African countries have local sustainability assessment processes for infrastructure development. Considering the vital role of infrastructure to Africa’s development, the identification of only a few countries with local sustainability assessment processes raises questions on the overall state of sustainability assessment in the continent. To date, there is no study that gives a definite account of which African countries have local sustainability assessment processes for infrastructure. The aim of this study was to conduct a systematic literature review to identify and analyze local sustainability assessment process for infrastructure development in an African country. Using PRISMA to guide the review process, the study showed that six processes have been created for infrastructure development in Africa. The African countries with these processes are Egypt (three)...

Several studies have investigated the deployment of such transportation systems. However, the role of a delineated planning stage of BRTs has been given limited attention. This study examined the role of planning in ensuring the sustainable performance of BRT systems. A qualitative approach using interviews with experts and BRT users in the Gauteng Province of South Africa was adopted. Findings indicated that planning should extensively encompass projections of the intended or future performance outcomes. These include institutional arrangements, existing characteristics and impact, service reliability and quality, technical analysis of infrastructural integration, demand, environmental performance metrics and life cycle costs. This inductive research advances the theory of critical factors that could potentially hinder the deliv...

Inadequate hostels for students in Nigerian Universities have been of great concern to Government and the University authorities. In the absence of public funds for infrastructure projects, the government’s attempt to attract the private sector in the provision of student housing has not recorded significant achievement. This study reports on the challenges faced by developers in adopting the Build Operate Transfer (BOT) model of project delivery with focus on public private partnerships (PPP) in Nigeria. The study found that developers perceive investment in student housing under BOT as worthy of investment. The study used a mixed method of data collection. One hundred and twenty questionnaires were administered to members of the Real Estate Developers Association of Nigeria, and interviews were conducted with the Nigerian Infrastructure Regulator commission (ICRC...

The many service delivery protests that are experienced in the previously disadvantaged areas/townships in South Africa are an indicator of the underlying problem of not being able to meet the commitments to eradicate or upgrade all informal settlements. Despite some of the achievements in delivering subsidised housing by the Department of Human Settlements, the housing backlog still remains at more than 2, 1 million housing units. The other indicator is the number of informal settlements. This research assesses the benefits of using digital mobile GIS tool for occupancy audit, beneficiary administration and maintenance of data base to improve Human Settlements in Ekurhuleni Metropolitan Municipality. The study has revealed that the use of the digital mobile GIS tool is beneficial for addressi...

Literature suggests that construction workers have poor nutrition and this adversely affects their health, wellbeing and safety on construction sites. Strategies to improve their nutrition warrant considerable attention. This paper aims to identify significant relationships between factors influencing nutrition and the food choices of construction workers. Empirical data for the correlational study were collected through a field questionnaire survey on site construction workers in the Gauteng Province of South Africa. Principal components analysis and Pearson‘s correlation analysis were conducted. Findings revealed that food context, nutritional knowledge, resources and personal ideas and systems were significantly associated with choice of foods. By highlighting the factors which are correlated with nutritional choices amongst construction workers, the study provides valuable evidence which w...

It is seen as a green new alternative binder to ordinary Portland cement (OPC) for sustainable infrastructure development. The strength of the unary or blended geopolymer product is dependent on the composition and properties of the polymeric gel influenced by the ratios of Al2O3/SiO2, CaO/SiO2, CaO/(SiO2 + Al2O3), Na2SiO3/NaOH, SiO2/Na2O, and liquid/binder (L/B). Essential scientific inquiry has been progressively addressed by utilizing expert assessment and research metrics. The network visualization of bibliometric co-occurrence and co-citations is of particular significance. The present study aims to highlight the trends and progress of the most influential publication sources, keywords, authors, articles, and countries in geopolymer research in the last 10 years. Bibliometric data were retrieved through Scopus and visualized in ...
