    Effective risk management practice and project success : the case of a water utility’s construction projects
    (Southern African Institute for Industrial Engineering, 2022-10-03) Javani, Blessing; Mamena, H.G.; Dewa, Mendon
    Failure to complete projects can significantly put an organisation’s competitive advantage, its strategic position, and competitive survival in jeopardy. The study sought to establish the effectiveness of applying project risk management tools and techniques at Rand Water, a state-owned entity. A quantitative approach with a survey research strategy was used in this study and 63 of the total population of 69 responded to the questionnaire that was issued. The Rand Water case study findings suggest that, in order to reduce project failure, one of the tools being utilized in managing projects is effective project risk management. In addition, the findings indicate that executive management must continue to apply project risk management tools and techniques coupled with regular project team training.

    Using system dynamics principles for conceptual modelling to resolve causes of rework in construction projects
    (University of Johannesburg Department of Construction and Quantity Surveying, 2015) Aiyetan, Olatunji Ayodeji; Das, Dillip
    Rework in construction projects has brought in two major challenges: cost overruns and delay. In this regards a study was conducted by considering various construction projects in the South West part of Nigeria to understand the causes of rework and the interventions to mitigate it. Survey research methodologies followed by the conceptual system dynamics (SD) modelling were used in the analysis. This study identified the sources of rework in construction projects from the design related, the client related and the contractor related issues and attempted to derive policy/strategic interventions to limit or eliminate rework on construction projects and its delivery by using conceptual SD models based on the influence of the variables on rework. The findings include that inappropriate scheduling for time pressure or delay at the planning stage, lack of adherence to specifications, and non-availability of skilled human resource are the major causes of rework. However, rework in construction projects would be reduced or eliminated through policy interventions, such as, achieving client satisfaction with scheduling for time pressure or delay at the planning stage, adherence to specifications ensuring quality of work resulting in client satisfaction, and the availability of skilled manpower ensuring quality management.
