- Description: Abstract: Transport infrastructure meets the demands for people and cargo delivery by providing access to working, shopping and travelling and improving the quality of life of citizens. Road infrastructure needs to be sustained for eons after its development. However, there is no consensus on the criteria upon which the operational performance of road infrastructure projects is assessed. This paper aims to identify all potential criteria for assessing road projects in operation. A desk study was conducted using relevant journal and conference papers obtained from databases including ASCE Library, Science Direct and Ebscohost. Thematic analysis was used to identify emerging themes from extant literature. The themes were tabulated and ranked based on their frequency of occurrence to determine the most important criteria for measuring the performance of road projects in operation. Findings indicate that institutional productivity and effectiveness, operational efficiency, health and safety, mobility, environmental element, public acceptability, asset value, legal and technical factors can be used to assess the performance of road projects. The study provides vital information which would be beneficial to project managers, and indeed investors, in assessing and projecting sustainable performance of road projects in operation.

- Description: Abstract: The health and safety (H&S) of construction workers has been a subject of much deliberation for decades. However, there is scant literature focusing on aspects of workers’ safety performance (SP) relating to their unhealthy and unsafe eating behavior. The paper presents findings on a principal components analysis (PCA) of H&S performance measures. A 10-item questionnaire which was developed after an extensive literature review was used to collect empirical data on SP of construction workers in the Gauteng Province of South Africa. Results showed that SP could be reasonably measured by two constructs. The two constructs were clearly defined by the PCA as trailing and prevailing. The emerged trailing measures were named lagging indicators while the prevailing ones were designated as leading indicators. The results lend support to extant literature which advocates the use of both leading and lagging safety performance indicators for effectively assessing construction workers’ safety performance. The study provides evidence which could be beneficial in psychometric evaluation of construction workers’ safety performance and behaviours on construction sites.

- Description: Abstract: Performance is linked with implementation of project management techniques. Lit- erature suggests that problems such as inefficiency, poor budgetary issues, improper planning, scheduling and control in projects execution are associated with inadequate implementation of the essential techniques for meeting project deliverables. These shortcomings are prevalent among Small and Medium Enterprises (SMEs) in the developing countries including South Af- rica. Hence, the primary objective of this paper is to review the critical project management tech- niques for the improvement of construction project performance especially among SMEs in South Africa. The study is based on previous literature on construction SMEs project performance as well as project management techniques implementation. The literature review centered on both international and South African context. The study revealed that critical path method, work breakdown structure, and earned value management analysis were the most occurring project management techniques from the sampled literature. Findings from this study are envisaged to be beneficial to construction stakeholders in developing relevant project management techniques to improve the performance of SMEs.

- Description: Purpose: Nutrition is linked with construction worker health and safety (H&S) performance. Some accidents, injuries and in some cases, deaths on construction sites are direct or indirect results of physical and psychological distresses (chronic health conditions and mental instability) arising from poor nutrition of construction workers. This alarming situation could gravely affect construction workers, their families, the industry and the economy as a whole since health will be adversely affected, performance will be hindered, avoidable on-site exigencies, injuries and sometimes deaths will occur, resulting in lost working hours or days, lost wages, increased healthcare costs, and decline in productivity and Gross Domestic Product. This study therefore reviews the factors which influence the nutritional uptake amongst construction workers and possible interventions. Methods: This study is based on review of previous literature on the construction industry and its H&S performance, as well as factors influencing nutritional uptake and nutrition interventions in the construction industry. The literature review was based on both international and South African context. Findings: The study revealed that construction workers’ nutrition is influenced by personal factors and environmental factors. The study also established feasible nutrition interventions based on these factors. Nutrition promotion initiatives need to target the different influences on construction workers’ nutritional uptake. Value: The study highlights construction workers’ nutrition influencers and reveals feasible strategies to improve nutrition and thus safety performance on construction sites. Practical implications: Findings from this study will inform development and implementation of programmes and policies targeted towards nutritional uptake tailored for construction workers.

- Description: Abstract : Globally, transformation is etched in all sectors of the economy. In the South African context, transformation is viewed as the catalyst to address the country’s socio-economic problems and their associated impact on different sectors and the economy at large. However, progress on transformation within the built environment has been slow in comparison with other sectors of the economy. As a result, this has led to a need to examine the transformation processes in the country. This article aims to analyse transformation strategies as conceptualised and implemented by various sectors. The article is based on a multi-case study of identified sectors and organisations that have developed and implemented transformation strategies. The materials used to conduct the study include sector transformation strategies, charters, journal articles, articles published in reputable South African newspapers, organisation reports, information publicly available on the internet, and interviews conducted with sector representatives. The findings show that, for all sectors, transformation strategies are driven through skills development of human resources, with a view to redressing historical imbalances and providing equal opportunities. The process of strategy development involves sector- wide participation and having a champion for the strategy. In order to ensure that strategies are implemented, specific structured training and education programmes from the grassroots to professional level, as well as monitoring of progress are emphasised. Recommendations are made in line with the findings in order to guide the Council for the Built Environment in the development of a strategy for the built environment.

- Description: Abstract: Sustainable transportation is vital since its impact traverses generations. The concept of sustainable transportation is known to account for incorporation of various elements including environmental, economic, social and institutional factors. The current study employed exploratory factor analytic technique using maximum likelihood factoring to identify critical indicators for assessing transportation infrastructure projects in South Africa. Using purposive and snowball sampling, a questionnaire was distributed via email, google forms and by hand, to project managers, directors, construction managers, planners and feasibility study consultants involved in transportation projects at different stages, in the nine provinces of South Africa. Empirical data amassed from 132 responses, were analysed using SPSS version 25 software.s Descriptive analyses were used for preliminary analyses. Inferential statistics was conducted using exploratory factor analysis, to output common factors and the minimum number of variables that were related to each construct. Findings revealed that a four-factor structure including infrastructure condition and impacts, user acceptability, financial management and safety and security, can adequately measure transportation infrastructure project sustainability. By establishing critical indicators for assessing transportation projects, the study provides relevant evidence to develop strategies to ensure that such investments bring lasting and desirable impacts in the long run. The study was conducted in South Africa and may not be generalisable to other geographical regions, which may have differing priorities with regard to sustainable performance of transport infrastructure. Further studies are on-going to validate the four-factor structure using confirmatory factor analytical techniques.

- Description: Abstract: It is pertinent that urban transport infrastructure developments do not disrupt the lifestyle, health, wellbeing and quality of life of the citizenry for which they are planned. The study aims to identify critical criteria upon which liveability can be measured in an area or location in which transport infrastructure development (new or capacity expansion) is proposed. Existing literature was reviewed and synthesised to identify liveability indicators used in previous studies. Review materials were sourced from accredited journals and conference proceedings. The materials were selected based on their currency and possession of the following keywords and phrases: liveability, sustainability, liveability considerations, liveability indicators, wellbeing of habitants, road planning, and transport infrastructure. Thematic content analysis was used to identify the emerging themes (liveability indicators) from the review. The factors identified were discussed based on their frequency of occurrence, which revealed the relative degree of consensus about them in the literature reviewed. Findings indicate that pollution, ease of access to amenities, services and opportunities, efficiency and effectiveness of service, safety and security, generally indicate liveability (in relation to transport development) in an urban area. Other indicators including availability of alternative modes of transport, reliability/travel time reduction, street aesthetic quality and economic vitality/business environment were also reported as benchmarks for urban liveability. By identifying the indicators of liveability in an urban area, the study provides valuable information that will be useful to road infrastructure planners in evaluating the impact of proposed road infrastructure developments on the environment and the citizenry for which they are intended. The major limitation of the study lies in the fact that it presents a distillation of extant literature which may not really reflect the reality of what is considered “liveable”. Nonetheless, planners will take cognizance of the identified liveability indicators when planning for road projects, whether for new road or capacity expansion.

- Description: Abstract: Infrastructure plays important roles in the development of cities, improvement in the quality of lives and overall socio-economic development and growth of economies. Infrastructure projects are, however, fraught with uncertainties regarding costs, benefits and performance. These uncertainties, if not accurately predicted in the planning of projects, could result in undesirable financial, social and economic consequences. The aim of the current paper is to identify critical factors which influence transport infrastructure performance forecasting outcomes and which should essentially be considered in order to minimize or eliminate errors. A review of related literature was conducted from journals, conference proceedings, magazines, theses and dissertations using databases including Science Direct, Emerald, Ebscohost, Academic Search Complete and ASCE library. The studies reviewed were based on international and South African context. Results revealed that project characteristics including size of project, capacity improvement and time lapses between construction life cycle phases, availability and type of data used, methodology used as well as traffic demand factors influence the outcome and validity of transport infrastructure feasibility studies. The study provides invaluable information to built environment professionals and stakeholders as well as infrastructure policymakers in accurately assessing probable outcomes, positive, in terms of benefits and negative, with regard to costs of proposed projects in order to avoid financial and economic risks. In addition, the study will be indispensable to infrastructure financiers and developers in effective allocation of scarce construction/development funds.

- Description: Abstract: Road transport projects are complex and laden with risks and uncertainties which influence their success or otherwise; even more so, with projects involving the private sector. Private investors decide to proceed with projects based on projections of costs and benefits potentially accruing to a proposed project, which ultimately reflect the success or failure of the project. However, the risks associated with roads delivered through public-private-partnerships (PPP) are grave and if strategies are not put in place to reduce or mitigate the chances of their occurrence, the expected performance of the projects may not be realised. The current paper aims to identify critical feasibility considerations to ensure sustainability of PPP road projects. A thematic content analysis of extant literature and case study illustrations was undertaken. Journal and conference articles were sourced from databases including Academic Search Complete, ASCE Library, Google Scholar, Scopus, Taylor and Francis, Google and Science Direct. Findings revealed that joint decision-making and concessionaire selection procedure and considerations were the most important feasibility factors for PPP road projects sustainability. These factors should be taken cognisance of at the feasibility stage to ensure that mechanisms are put in place in order to realise expected project performance.

- Description: Abstract: Road transport projects are complex and laden with risks and uncertainties which influence their success or otherwise; even more so, with projects involving the private sector. Private investors decide to proceed with projects based on projections of costs and benefits potentially accruing to a proposed project, which ultimately reflect the success or failure of the project. However, the risks associated with roads delivered through public-private-partnerships (PPP) are grave and if strategies are not put in place to reduce or mitigate the chances of their occurrence, the expected performance of the projects may not be realised. The current paper aims to identify critical feasibility considerations to ensure sustainability of PPP road projects. A thematic content analysis of extant literature and case study illustrations was undertaken. Journal and conference articles were sourced from databases including Academic Search Complete, ASCE Library, Google Scholar, Scopus, Taylor and Francis, Google and Science Direct. Findings revealed that joint decision-making and concessionaire selection procedure and considerations were the most important feasibility factors for PPP road projects sustainability. These factors should be taken cognisance of at the feasibility stage to ensure that mechanisms are put in place in order to realise expected project performance.

- Description: Abstract : Alternative investments including real estate project, and especially non-conventional investments such as agricultural and game lands are fraught with management risks, which if not taken cognizance of, might threaten their value in the long run. The study aimed to identify critical factors, which influence the value and sustainability of such estates and thus should be considered in valuations of such property. A distillation of information from extant studies was undertaken to identify the factors which contribute to the performance and thus value and profitability of agricultural and game estates. Content analysis was used to analyse the findings. The findings indicated that financial outlay and flow, regulations and policies, government incentives, personal zeal, and management efficiency, land prices, currency fluctuations, and climatic elements (rainfall, drought) were important value considerations for agricultural properties. By identifying these factors, more effort can be made to incorporate them in valuations of such properties. In addition, strategies to ensure that the value and benefits thereof, of such “alternative investments” are sustained in the long run, will be informed.

- Description: Abstract: A considerable number of people considered to be living in extreme poverty are located in sub-Saharan Africa. To eradicate extreme poverty, it is imperative that investment in infrastructural development – such as transportation projects - is encouraged in countries hit the hardest by poverty as infrastructural development plays a key role in reducing extreme poverty and driving sustainable economic growth. Although investment in infrastructure has increased significantly over the past two decades, concern abounds regarding the performance of some transportation projects. Several factors such as ineffective procurement processes have been identified as factors that lead to poor transportation project performance in several countries. Moving to more innovative procurement and financing practices such as Public-Private Partnership (PPP) could spur economic growth. Due to its unique integrative risk sharing platform, PPP is considered an effective project delivery strategy that could drive infrastructural development. Nevertheless, barriers to the wide adoption of PPP on transportation infrastructure exist. To improve the success rate, it is vital that critical success factors (CSF) are identified. No prior study succinctly summarized the CSF needed for successful implementation of PPP on transportation infrastructure projects in emerging markets. Using an integrative literature review process, 24 CSFs were identified. Thorough and realistic cost/benefit assessment, social support, transportation infrastructure meets a need, political support, and technical feasibility of project was considered the most important CSF based on appearance frequency. Subsequently, three case studies were examined to ascertain the applicability of the CSF within the context of a developing country. Results indicate that the top 8 ranked CSF were identified in the three case studies. This indicates the presence of some similarity between the CSFs for implementing PPP on transportation infrastructure in developed and developing countries. The study recommends the development of adaptable frameworks that would improve the future implementation of PPP on transportation projects in developing countries.

- Description: Abstract: Against the backdrop of an increasing demand for efficient, effective, and sustainable infrastructure this chapter uses data from two rapid railway transportation projects, the Gautrain in South Africa and the Addis Ababa City Light Rail Transit (AA-LRT) System in Ethiopia, to explore how capital-intensive infrastructure is delivered in Africa despite the many bottlenecks in the environment. Adopting a comparative approach, we illustrate how the two “megaprojects” were organized to deliver on the intended objectives and how they dealt with complex interfaces with the surrounding contexts. In each case, we evaluate how the project was sponsored and organized, the institutions surrounding the project, and whether there was a trade-off between project efficiency, effectiveness, and sustainability Specifically, we find that project governance is directly influenced by the political and socio-cultural environment surrounding the megaproject. Therefore, we argue that project organization to deliver large infrastructure in Africa is not a one-size-fits-all solution.

- Description: Abstract: Nutrition is linked with construction worker health, wellbeing and productivity improvements. Unhealthy eating may result in reduced immunity, increased proneness to developing chronic diseases, reduced concentration and alertness and reduced productivity. Improving the nutrition of construction workers is therefore of paramount concern. Although it is generally acknowledged that improving nutrition requires an understanding of the factors which influence construction workers‟ food choices, it has also been shown that the first step in achieving healthy eating is through increasing nutritional awareness and knowledge which will help in inculcating positive nutritional behaviour. The present paper therefore aims to highlight the state of nutritional knowledge among construction workers and possible ways of increasing nutritional awareness. A review of literature related to nutritional knowledge of workers, as well as health, safety and productivity of construction workers, was conducted. Sources included web- based journal and conference articles, magazines and reports. The distillation of literature through thematic analysis revealed that construction workers are aware of the benefits of nutrition in improving their health, safety and productivity, albeit it is seldom reflected in the food choices they make. The study also established that nutrition education programmes which target specific audiences and go beyond disseminating information to creating an enabling environment, ultimately beget long-term positive nutritional behaviours. The study concludes that increasing awareness of the importance of nutrition education and similar interventions could primarily improve construction workers‟ nutrition and in turn, health, safety, wellbeing and productivity. It is recommended that construction stakeholders view nutrition education as an integral aspect of health and safety training on sites. It should be mandatory for companies to have nutrition training sessions for employees on a continuous basis.

- Description: Abstract: Non-motorised transportation (NMT) infrastructure, including for walking, cycling and other forms of active or human-powered transport, is a key part of the overall transport network of any "smart" city. Attention to key factors that could potentially influence the sustainability of NMT infrastructure systems at the planning stage is arguably crucial in achieving a sustainable and smart transport network. This study examines critical factors taken into account in the planning and delivery of NMTs to ensure the delivery of sustainable and smart transport networks. Three projects in Johannesburg, South Africa were selected using convenience sampling, based on the availability of information. Document analysis and interview were employed for data collection. Thematic content analysis was conducted with the aid of atlas-ti software. Findings revealed that community’s specific needs with regard to accessibility and services, design, costs, distribution and speed of traffic, distances, as well as occurrence of accidents and incidents were critical factors considered in the planning of NMT infrastructure. Other factors included locational characteristics such as topography, and existing land uses which may affect facility costs and integration of NMT infrastructure. The provision of non- motorised transport facilities, not only ensures the safety of road users, but improves liveability and quality of life and welfare of communities, as well as environment and as such, attention to the factors which should ideally be considered at the planning stage to ensure sustainability of the NMT system is vital.

However, few studies exist which focus on the sustainable outcomes which an infrastructure investor seeks when deciding to invest in a project. The current study reviews extant literature to identify factors which are indicative of sustainability, specifically to an investor. Transportation literature is focused on because of its economic nature and potentiality of returns to an investor. Studies in both international and South African context are included. Findings revealed that adequacy of funding, accessibility, safety and security, quality, reliability, environmental friendliness and strong institutions are desirable outcomes to an investor. These findings will assist in the development of strategies to ensure that infrastructure projects are financially and economically sustainable.

- Description: Abstract: Transportation infrastructure provision is critical to the development of urban areas. Transport infrastructure such as roads, bridges, and ports are increasingly becoming the corner stone in determining the strength of cities, improving the quality of lives and overall socio-economic development and growth of economies. However, these projects are stochastic in nature and fraught with uncertainties which, if not accurately predicted, can lead to inadequate assessment and management of risks. The aim of the present paper is to identify critical factors which moderate traffic demand over a long period of time, and which should ideally be included in transport demand forecasts. A detailed review of literature was conducted from online journals, conference proceedings and theses using databases including Science Direct, Ebscohost, Google, Emerald and ASCE Library. Findings show that socio-economic factors (such as income, age, employment, vehicle operating costs, fuel price and tax polices), sociocultural factors (such as security, comfort, alternative/competing transport modes, leisure time), and environmental factors (such as pollution, traffic congestion, distance from station and frequency of trips) influence traffic demand. These findings would provide valuable evidence for adequate management of risks in infrastructure planning, and for public policy.

- Description: Abstract : Objectives: The nutrition of construction workers is related to their health and safety (H&S) at work. Research on the factors influencing construction workers’ food choices and overall nutrition is limited, in South Africa and indeed Africa as a whole. The present paper aims to develop and validate a questionnaire on factors influencing construction workers’ food choices. Design: The study adopted a quantitative approach; 42 items, divided into six constructs, were used to develop a field-survey questionnaire after a detailed literature review. Setting: The study was conducted on eight construction sites (consisting of five building construction and three road construction sites), chosen through heterogeneity sampling, in Midrand, Centurion, Johannesburg and Samrand. Subjects: Participants included construction workers actively involved in site activities. Outcome measures: Principal components analysis (PCA) was conducted to examine the structures and validity of the constructs. Cronbach’s alpha test and mean inter-item correlations were used to examine internal consistency reliability. Results: After repeated factor analysis, the questionnaire on food-choice factors revealed seven different factors: food context, biological factors, nutritional knowledge, personal ideas and systems, economic factors, resources and cultural background. These factors explained 60.09% variance. Cronbach’s alpha coefficients ranged from 0.62 to 0.85, signifying good internal consistency reliability. Conclusion: The determinants of construction workers’ food choices are vital considerations when designing and implementing nutrition interventions in the South African construction industry. Future research can adopt the instrument and developed model when conducting psychometric evaluations of construction workers’ food-choice determinants.

- Description: Abstract : Objectives: The nutrition of construction workers is related to their health and safety (H&S) at work. Research on the factors influencing construction workers’ food choices and overall nutrition is limited, in South Africa and indeed Africa as a whole. The present paper aims to develop and validate a questionnaire on factors influencing construction workers’ food choices. Design: The study adopted a quantitative approach; 42 items, divided into six constructs, were used to develop a field-survey questionnaire after a detailed literature review. Setting: The study was conducted on eight construction sites (consisting of five building construction and three road construction sites), chosen through heterogeneity sampling, in Midrand, Centurion, Johannesburg and Samrand. Subjects: Participants included construction workers actively involved in site activities. Outcome measures: Principal components analysis (PCA) was conducted to examine the structures and validity of the constructs. Cronbach’s alpha test and mean inter-item correlations were used to examine internal consistency reliability. Results: After repeated factor analysis, the questionnaire on food-choice factors revealed seven different factors: food context, biological factors, nutritional knowledge, personal ideas and systems, economic factors, resources and cultural background. These factors explained 60.09% variance. Cronbach’s alpha coefficients ranged from 0.62 to 0.85, signifying good internal consistency reliability. Conclusion: The determinants of construction workers’ food choices are vital considerations when designing and implementing nutrition interventions in the South African construction industry. Future research can adopt the instrument and developed model when conducting psychometric evaluations of construction workers’ food-choice determinants.
