- Description: Economic sustainability and reconstruction in many economies rely heavily on the construction sector and remain strategic tools for governments and industries worldwide. Excessive construction costs and materials waste among some construction companies are rampant in the construction sector. Most of this waste is poorly managed, thus triggering significant project failure problems, leading to the project stakeholders losing the value of their investment. This concern advocate for effective control of construction material to avoid wastage. The primary objective of this study was to develop a Construction Waste Material Control (CWMC) model to be used by construction project professionals throughout the Project Management (PM) phases: initiation, planning, execution, monitoring, control and closure. Significant literature on construction materials waste, Project Management (PM) processes, and project performance regarding poor waste management and project failure was reviewed. This literature review was conducted to identify factors affecting Construction Waste Material Control (CWMC). These factors were identified and defined together with their respective contributions to the model. A quantitative survey instrument (questionnaire) was used to obtain information from construction sector professionals. A total of 213 questionnaire were received and administered for the study. Structural Equation Model (SEM) SEM was used to analyse the questionnaire data, and thereby assisting the research to clearly define latent constructs statistically significant to the (CWMC) model. The finding was that, the factors identified to have impact on CWMC are Project Initiation Phase Tools (PIPTs), Project Planning Phase Tools (PPPTs), project failure/success factors (PFFs), Project Execution Phase Tools (PEPTs), Project Monitoring and Control Phase Tools (PMCPTs), Construction waste material Control (CWMC) policy and Project Management (PM) competence. The supported hypotheses also authenticated these factors. Introducing the model into the construction sector provides another dimension to CWMC. By establishing the aforementioned factors, the model gives construction professionals precise CWMC predictive accuracy. As the model reliability test of 0.734 to 0.972 satisfied the theoretical threshold and goodness of fit of 0.912 of Normed fit index respectively. The model is the first of its kind and contributes significantly to the construction sector’s existing body of knowledge. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, School of Built Environment and Civil Engineering, 2024

- Description: Construction is a big role player in every economy, and the Site Management Process (SMP) occupies a strategic position in the construction process. Despite existence of appreciable research, technology diffusion in the construction industry is slow. Information and Communication Technology (ICT) implementation processes and products have not adequately and beneficially exploited ICT for improvement of the SMP. This is especially true in developing countries. Without increase in utilisation of ICT, potential benefits for the SMP remain untapped. The aim of the thesis was to ascertain the levels of utilisation of recent ICT developments for the SMP, and thereby gauge the benefits or lack thereof. The theoretical concept of the research is based on the technology transfer sub-concept of adaptation. A fundamentally positivistic view, with principles of objectivist approach was used for the enquiry. The approach included an extensive literature review, and a multi-stage investigation strategy, set in South Africa. Theory reviewed was in the main disciplines of construction science and technology, computer science and technology, and management science. Investigations involved case studies of construction sites, a global ICT survey, a national practitioner survey, and analysis of ICT products. Findings from literature assert the appreciable potential utility in recent ICT, thereby substantiating the adaptability of recent ICT. In addition ICT adoption in the SMP is inadequate and inexpedient, falling short of potential benefits for construction, both generally and in the local context. Furthermore there are challenges to ICT adoption, which could vary according to context. Field research results also point to underutilisation of innovations located in recent ICT. The main challenges in this regard include inadequate knowledge of potential utility of recent ICT, and lack of relevant support and effective approaches to technology integration, in the SMP. Moreover exploitation of the adaptability of recent ICT in the local SMP does not go beyond basic adoption. As such most diffusion occurs only for items requiring an adaptation of usage context or area of application. The results strongly indicate minimal innovativeness in this regard. Frameworks for possible adaptations of existing technologies were also derived, while propositions are made for approaches to improve the utility of recent ICT in the SMP. Through a customised approach, the thesis establishes foundational understanding towards a generic framework for adapting potential utility in ICT to uses in construction, especially in the SMP. Thus the research contributes strategic information to the fledgling CICT body of knowledge, especially in the local context.
