    The application of urban design principles to create habitable, safe and self-sustainable urban precincts: the case of Centurion Gautrain Station Precinct
    (2020) Nyoni, Barnet
    Through urban design a number of spatial and developmental challenges can be mitigated or completely eradicated, thus appropriating urban spaces in order to create robust urban environments for humans to work, live, shop and play. In so doing, a number of urban design tools and urban design principles are applied in transforming undesirable urban environments. Economic stimulation, through the optimisation of public transport infrastructure is also possible. This research aims to establish what constitutes a robust urban environment, identify the key urban design principles that can be used to transform an undesirable urban precinct to desirable and robust urban precincts. These principles are then applied to the study area, which is bounded by Lenchen Avenue, Jean Avenue, Gerhard Street and John Vorster Avenue. Though this precinct is highly accessible with a wide range of land uses, it is relatively underdeveloped. The precinct is inundated with development challenges that include, fragmented development, lack of essential public amenities, unsafe public spaces and vehicular/ pedestrian conflict to mention but a few. This precinct is a business core for the City of Tshwane and is highly connected with easy access to the major national roads like the N1 and the N14. It was developed with the main aim of decongesting the congested commercial activities in the Pretoria CBD. Owing to its strategic location, the study area has potential to be commercially viable, and a thriving hub with mixed economies that can be safely used by people. The theme for this research is “The application of Urban Design Principles to Create Habitable, Safe and Self-sustainable Urban Precinct: The Case of Centurion Gautrain Station Precinct”. The main research question being “What role can urban design principles play in transforming undesirable urban spaces to desirable urban spaces?”. Keys concepts from Responsive Environments relating to permeability, variety, legibility, robustness, visual appropriateness richness and, personalization will be applied to the study area through design

    Feasibility assessment of projects for risk of failure: how feasibility assessment are done for infrastructure projects
    (2019) Smith, Ronald George
    Avoiding project failure is a concern within the discipline of project planning and management. Feasibility assessment is a front-end process used in project planning to analyse risks and avoid failure. The aim was to explore how feasibility assessments for large infrastructure development projects are conducted and the extent to which risk of failure is recognised. Literature review established theory and definition of feasibility assessment as applied to projects. Two cases of large scale infrastructure development projects in South Africa were investigated to compare different approaches of how feasibility assessments are conducted. Methodology was a combination of direct observation, interviews and analysis of documents collected from the case studies. The predominant risk factor recognised by expert feasibility assessors in both cases was found to be perception of risk itself. Questions asked of the experts are designed to lead to a confirmation that the project could go ahead. The questions do not necessarily ask opinion on whether the project should go ahead. Comparison of the cases showed that the process of feasibility assessment was driven by each assessing firm’s own interpretation of the purpose and objective of feasibility assessment. Overall, the study confirms that the feasibility assessment process is useful as a way for project managers to recognise risk of failure before deciding to proceed with a project. However, the process depends on each assessor’s own interpretation of the definition of feasibility assessment and its purpose. Further research is suggested into the distinction between the reasons justifying why a feasibility assessment was not done, and the reasons why feasibility assessment was not considered for a project
