Emerging contractors play a critical role in the South African economy in terms of rendering services to government especially in the construction sector. However, literature findings reveal that some of the SMMEs are unable to deliver their projects successfully due to project management issues. The focus of this study was to establish the project management factors influencing the successful delivery of construction projects by emerging contractors in the Mahikeng area of South Africa. A mixed design research method was used to collect, analyse and derive the findings. Findings revealed that projects do not comply with the time, scope, cost and quality requirements. Focus group interview results attributed these problems to lack of project management skills among the emerging contractors. It is recommended that more support initiatives from the South African Department of Public Works, and other key stakeholders in the construction industry be provided to these contractors

Although implementing quality assurance (QA) processes in construction play an important role in the South African economy has been acknowledged. However, constructions SMEs are faced with difficulties in improving rural road infrastructure and high-quality roads. Additionally, past research has failed to reach consensus on the construction process and socioeconomic settings in previously disadvantaged areas in South Africa, including the factors influencing negatively the performance of such factors. This research examines what factors facilitate or inhibit the success of construction SMEs and what actions can be taken to being distressed construction SMEs under control. The study adopted a quantitative research approach in which a three-section questionnaire was administered to 160 purposively chosen road- building experts in a South African construction SMEs. The questionnaire was structured into three parts, which sought the participants’ profile, identified the quality assurance practices (QAPs) incorporated in the construction SMEs’ road building programmes, and identified the factors that negatively influence the implementation of QA processes. Data was analysed using the Statistical Package for the Social Sciences (SPSS) version 22. Furthermore, to determine the reliability of the various constructs, mean scores, descriptive statistics and standard deviations were obtained. The empirical findings established eight QAPs that were reliable and valid for implementation processes that can control or minimise their causes of poor quality in projects undertaken by construction SMEs, level of skill acquisition; project planning and control techniques; project construction design; process implementation and process improvement; financial management; organisational structures; involvement of people; and quality standards and measurements. The eight factors attained high Cronbach Alpha values above the recommended 0.70 which indicates high internal consistencies among the sub-scales. Findings from this study should be useful to managers in similar environments may use the results of this study as either diagnostic tools or as a reference benchmark for strategic interventions in solving construction projects related problems. Furthermore, the researchers also recommend that these practices are for quality assurance in construction projects undertaken by SMEs in South Africa.

Kidney transplantation is the cornerstone for renal treatment in patients with end-stage renal failure. Despite improvements in short-term outcomes of renal transplantation, kidney allograft loss remains a huge challenge. The aim of the study was to assess factors influencing the durability of transplanted kidneys among transplant recipients in South Africa. A descriptive cross-sectional study design was used. A random sampling was used to select 171 participants. Data were collected through structured face-to-face interviews developed from in-depth consideration of relevant literature. Data were coded and entered into the SPSS software, version 24. The entered data were analysed using descriptive and inferential statistics. The results revealed that the average durability of transplanted kidneys was 9.07 years among selected kidney transplant recipients in South Africa. Factors associated with the durability of transplanted kidneys included age, the sewerage system and strict immunosuppressive adherence, all with a P-value = .000, followed by the mode of transport (P-value = .001) and support system (P-value = .004). Other variables including demographics, the healthcare system, medication and lifestyle modification engagement were not associated with the durability of transplanted kidneys. Understanding the factors influencing the durability of transplanted kidneys among kidney transplant recipients in South Africa is crucial. The study revealed associated factors and gaps which may be contributory factors to kidney allograft loss. This study provides an opportunity to introduce specific interventions to nephrology professionals to promote prolonged graft durability. It is recommended that a specific intervention model be developed, which targets South African kidney recipients taking into account the significant variables in this study and the socio-economic status of the country.
