- ItemAn evaluation of the applicability of the extended situational leadership model to lower level management in the South African construction industry(University of the Witwatersrand, 1990-08-10) Cocotos, GeorgeThe vast majority of theories and models that have been developed around the concept of leadership have been conceptualized, and tested in the USA and other countries outside South Africa as discussed in the literature survey, Chapter 2 of this dissertation). Furthermore, the models developed have largely been theoretical models aimed to help leaders only to identify the most appropriate leadership style to use. None have however attempted to develop a model that leaders can use to implement the most appropriate leadership style once it has been chosen. Consequently, A D Jaff, using the most integrated and recently developed Situational Leadership Theory and Mode 1 of Hersey and Blanchard as a data base, developed the first leadership implementation model - The Extended Situational Leadership Model. Since AD Jaff's implementation model is a combination of various other leadership mode ls and theories, in order to fully understand the development of the Extended SL Model, all the relevant models are researched in this dissertation (see Chapter 2). This dissertation attempts to test the applicability of the Extended SL Model in a practical construction environment in South Africa. It further attempts to make adaptations to the model where relevant, after testing its performance value through the administration of 3 questionnaires to a sample of potential/practising black leaders (on-site construction managers). (This lS surveyed in Chapters 3 to 6 of this dissertation). The objective of this dissertation is therefore to attempt to test, and where necessary, to adapt AD Jaff's Extended SL Model so that : 1) this theoretical model may be implemented practically in a South African construction working environment (i.e. to prove that the mode 1 does work in practice) ( see Chapter 4). and to test whether 2) the adapted mode 1 is applicable for the training of future black Low-Level leaders in the South African construction environment. The adapted form of the model will, I believe, prove to be a useful tool for the training of black leaders within the South African construction organisations, where the volatile industry and changing economic and political environment of South Africa with ensure the emergence of black South African Low Level leaders in the construction industry in the near future.
- ItemInvestigating quality in construction in the residential sector around the Gauteng region(University of Witwatersrand, 2016-10) Mulla, Mohamed; Crossman, Richard; Nyalunga, SikhulileAccording to the Construction Industry Development Board (CIDB), quality in the residential sector in South Africa is the least satisfactory among all sectors. It is therefore important to research further into this sector to establish the current state of quality and factors that affect it from homeowner’s perspective. The key purpose of this study is therefore to investigate the level and factors that affect the quality of construction in recently developed (in the 12 last years) private estates in Johannesburg, South Africa. Literature was used to determine factors that affect quality in residential properties. These factors were then used to design a questionnaire that helped to determine the level of quality in estates in the Johannesburg region. Quality has been found to be of a satisfactory level however some notable points were raised from respondents regarding some underperforming aspects. These factors are floor finishes, running costs, outside area of the home, general aesthetics of the home, ambient temperature, natural lighting, parking area, air conditioning and delays in construction These factors are analyzed and recommendations for future studies have been made.
- ItemInvestigating how ICT affects the performance of geographically dispersed construction project teams within South Africa(University of Witwatersrand, 2016-10) Cele, Sibhekiwe; Mashao, Morongwa; Mokoka, WilheminahThis study examines how information and communication technology (ICT) affects the performance of geographically dispersed construction project teams within South Africa. It focuses on how project team dispersion due to the geographic separation of the project location from the construction teams’ primary facility affects performance and how the project teams make use of information communication technology (ICT) to address the challenge of executing the project. This will be done by looking at the means in which the ICT is used, the seven ICT perspectives and how they are applicable to the project teams, the processes and mechanisms in place to deal with the communication requirements to performance and, as such, attempt to measure the perceived performance of the construction project teams. The mixed method research methodology is adopted in the study in order to fulfill its objectives that span the collection of primary and secondary data. The limitation of the study is that data collection is limited to addressing and questioning potential respondents only within the in the Gauteng province - predominately in Johannesburg, South Africa. As a result, findings from this study cannot be freely generalized beyond the Metropolitan or provincial sample group. Nonetheless, the findings will form a basis for a future research. Undertaking this study will shed light to project parties about the importance of incorporating information communication technology processes to manage and alleviate the challenges faced with handling the performance of geographically dispersed construction project teams.
- ItemInvestigating collaborative procurement processes in green buildings(University of Witwatersrand, 2016-10) Mohale, Lerato; Mamathuba, Mulalo; Mochalibane, BontleIt has been acknowledged and appreciated on a global scale how climate change has direct negative effects on the environment, economy and society as a whole. The construction industry’s response to this is the introduction of green buildings. However, green innovations are far from becoming customary due to insufficient knowledge in the implementation of procurement processes. The use of a dominating default method known as traditional procurement practice is being implemented which hinders successful project delivery as it neglects the collaborative intensive nature of green buildings. The aim of the study is to determine the changes that occur in the procurement processes of green building at Wits University, to establish the most suitable process that is aligned with achieving high performance through project delivery. The study adopted a qualitative research approach suited for exploratory research where the nature of a problem is being investigated. A total of three project participants including the project manager, contractor and quantity surveyor involved in the erection of New John Moffat Building, Maths Building and Wits Science Stadium participated in the study. Open-ended interviews were used to explore the nature of collaborative procurement processes adopted during the lifecycle of each building. The use of framework agreements fostered collaborative practices as they were deemed suitable for green buildings. As much as we are unable to conclude that traditional procurement is inadequate for green buildings, we were able to establish that when incorporating green elements into a structure, traditional procurement does not sufficiently conform to sustainability parameters.
- ItemSustainability in project management in the South African context(University of Witwatersrand, 2016-10) Chothia, Tasmiyah; Booi, Zanoxolo; Madonsela, NikiweThe research study is commissioned to analyse the application of sustainability in project management, with particular reference to the difficulties experienced when applying sustainability into project management that affect the goal of achieving project management and sustainability in South African construction projects. Global warming is considered to be a worldwide concern and the construction industry has been concerning itself with the concept of sustainability in order to minimise their impact on the environment, the resources and their contribution towards global warming. Implementing sustainability into the construction project process assists in reducing these impacts, however there are a range of challenges due to the change from the traditional way of constructing and managing the project. As a result, project managers are faced with difficulties when implementing sustainability into their project management practices which has an impact on their objectives. The study has adopted a mix method research methodology by using both primary and secondary sources in order to achieve its aim and objectives with a limitation to the primary data being information collected only from professional project managers within South Africa. This research uses an inductive approach to collect qualitative data. The study comprised of the collection of data from formulated questions that were in line with the findings of the literature brought to the South African context as well as questions against what the literature was not able to provide for. These questions were presented in the form of an online questionnaire as a survey to a drawn sample of construction project managers registered with the South African Council for Project and Construction Management Professions. The research reports on the data collected from eighty-nine participants with and without sustainable building experience in order to obtain the experienced and the perceived to be experienced challenges. After this process, the data was analyzed through the use of categorization of data and graphs to compare data collected. The findings from this study reveal the significant challenges experienced by project managers when implementing sustainability into their practice. Similarities between what the literature says and what the South African respondents stated were found.
