Item Challenges during installation and maintenance of water delivery infrastructure : a citizen perspective(Beykent University, 2023-10-30) Mokgobu, Matlou Lesley; Mason, Roger; Dobbelstein, ThomasThe installation and maintenance of water infrastructure in South African cities poses a challenge to communities, municipalities, and installation contractors, who face problems such as inadequate access to homes, traffic jams, inadequately barricaded trenches, leaking water pipes, water supply cut offs, vandalism, and theft of water. The research problem, therefore, involves an inadequate understanding of what drives these problems and how to mitigate them through better management. The aim of this study was to investigate the challenges of managing water infrastructure as perceived by the citizens of a South African municipality. The study was a descriptive and cross-sectional survey, with data collected, via a literature derived, emailed questionnaire, from a self-selected non probability sample of 402 City of Tshwane residents. Analysis, via SPSS Version 27, used descriptive and inferential statistics. The findings revealed that both the municipality and the contractors contributed to the challenges experienced by citizens, with maintenance challenges being more serious than installation challenges. Municipal and political challenges were the main drivers, with political ownership of construction companies and political interference being the biggest problems. The findings contributed to a better understanding of the challenges inhibiting effective installation and maintenance of water infrastructure, and are important to the municipality, and the community at large, because they contribute to a better understanding of service delivery from the citizens’ perspectives.Item Optimising corrective maintenance backlog using quality tools and quality principles at a selected power generation plant in South Africa optimising corrective maintenance backlog using quality tools and quality principles at a selected power generation plant in South Africa(2022-04) Maseola, Matshidiso Moses; Ramchander, ManduthThis study is located within a power generation plant based in the Free state province of South Africa. Corrective maintenance is a challenge in the power generation plant which created corrective maintenance backlog. This emerged as a significant challenge for the power generation to address. According to previous studies, there has been minimal improvements in the coal-fired power generation plants in South Africa. This has created an environment where power generation is through aged infrastructure with high maintenance. South Africa, with its current power generation challenges, has a direct negative impact on global investors. It is critical to meet electricity demand to power the current and future economic needs of the country. The aim of the study is to optimise the corrective maintenance backlog at a selected power generation plant. In this study, a combination of qualitative and quantitative research methods were applied. A questionnaire was sent to the power generation plant employees. Top management was interviewed, and secondary data on corrective maintenance and documentation was analysed. This study looked at integrating essential quality tools and ISO 9001:2015 Quality Management Principles to optimise the corrective maintenance backlog. This integration brought about a practical and implementable framework that the power generation plant can apply to improve the execution of maintenance activities and thus reduce the corrective maintenance backlog.
