- Description: M.Ing. (Engineering Management) , Abstract: Water and sewer infrastructure systems have numerous complex components from a mu-nicipal operational and maintenance perspective such as recurring water pipe bursts and sewer blockages. This prompted the study to assess, analyse and quantify the characteristics of factors that compromise water distribution and sewer services reliability around Johannesburg (used as a case study). The aim of the study is to investigate water and sewer infrastructure challenges by researching the relationship between operations, maintenance, design and construction. Furthermore to develop a short-term framework that should improve the day to day operations based on data findings that highlight common failures. The common trend found in the literature case studies is the use of a water audit as a basis for assessing bursts, blockages, leaks and water losses. The water audit approach enables researchers to discover patterns in big data without formulating hypotheses by using a grading system (Lycett, A., 2013). Prioritizing water and sewer projects based on complaint loggings from residents are a common trend within the case studies. Existing frameworks from an Operations & Maintenance (OM) perspective responded to problems according to a level of response criteria and category to prioritize pipeline failure accordingly. The common software trend in literature is the Geo Information systems (GIS) database integrated with Systems Applications Product Plant Maintenance (SAP PM), CCTV, Computerized Maintenance Management System (CMMS) where pipeline works for water and sewer are updated on the database drawings than loaded (East Water Valley District, 2014) on Information Management systems(IMS). The Johannesburg Metro Council had approximately 61.5 water and 50.5 sewer blockages/spillages related failures reported per day. An approximate total of 112 infrastructure failures were recorded daily. Data found for water infrastructure highlighted Asbestos Cement (AC) pipes grading had the worst case with Grade E, which was water infrastructure, unfit for intended purpose. AC pipes needed to be replaced as the rate of failure or frequency of failure was too high at approximately 97.56%, however, pipe accessories e.g. valves, hydrants and meters had a Grade C system which were systems that were mediocre and required attention. The pipe accessory failures were not dreadful, but needed some attention to fix the failures through a framework. Roots in sewer pipes were the main cause of sewer blockages and spillages. A grading of Grade E for sewer infrastructure was obtained, which was sewer infrastructure unfit for intended purpose. In contrast foreign material deposited in the sewer line obtained Grade C which was systems that were mediocre and required attention. Sewer overflows were due to capacity issues and obtained Grade A, which...

- Description: M.Phil. (Engineering Management) , Abstract: Design, engineering and construction projects are inherently complex by nature, let alone when multiple disciplines and organisations are involved. The rapid development of technology, size of projects and speed to market are all factors to consider to remain competitive, efficient and profitable in a global market. Engineering managers are finding it increasingly more important to be equipped with additional administrative and commercial skills to adapt to continuously changing environments. Organisations are forced to be innovative and creative by developing effective management and planning strategies with sound decision making processes. All stakeholders are required to pay more attention to the difficulties and problems experienced with interfacing and change control than ever before. This study presents the problems experienced with interface and change control management and the benefits of implementing effective interface and change control processes. Interface and change control management frameworks are proposed to mitigate the impact of problems by encouraging meaningful communication between all stakeholders to focus on the objectives to complete projects successfully within time, budget and to performance requirements.

- Description: M.Phil. (Engineering Management) , Abstract: Didactic Solutions Engineers are engineers who are involved in providing sales, marketing, training, and customer solutions of learning systems in an organization. The complexities attached to the nature of Didactic Solutions Engineers functions within an organization often create a sense of exhaustion, thus reducing their productivity and efficiency. The challenges are increasingly intensified by the rate of development of new technology. In less than a century, technology has evolved from the first industrial revolution to the fourth. Didactic and Learning Systems companies are growing part of the industrial business industry. Didactic focussed companies design, build and distribute learning systems equipment to address the skills gap in the engineering and technology field. The increased need for technological sales teams and client needs to stay abreast of technological development result in more pressure. Companies’ sales teams are put under pressure due to few resources resulting from the global economy and the subsequent increases in the footprint area that needs to be covered. Systems Engineering is an interdisciplinary approach that aims to solve complex problems by combining systems, subsystems and their components. Through a series of well-defined steps, Systems Engineering defines the customer needs and progresses further towards design synthesis, realization, optimization and validation of systems. Systems Engineering tools and methods can be used in different fields to optimize the outcome of a process, by the fact that attention is devoted to the entire life cycle of the systems. Traditionally, Systems Engineering has evolved independently and there are numerous tools and techniques available to address systems design issues. This research study seeks to investigate the experiences of didactics companies outside South Africa and look at the daily activities of Solutions Engineer within Festo SA. A framework to optimize the function of a Solutions Engineer in didactic market will be designed based on those findings using Festo South Africa (SA) as a case study. For the derivation of the framework, data was collected using questionnaires that helped obtain relevant information on daily activities (sales, exhibition, marketing, tenders, project and technical solutions) from Solution Engineers within Festo SA and other didactic companies in the world. The collected data was analysed. Systems Engineering tools and methods were applied and from that, a framework was proposed to help Solutions Engineers with their daily work. In addition, two new alternative organograms were proposed in this study to be adapted to the proposed framework for future implementation to help the Solutions Engineers.
