Abstract
Effective project planning and scheduling helps to ensure that the projects are delivered within cost; within the time constraint; and to a specific standard of quality (SAD, 2000). Hence, planning and scheduling embeds the primary objectives of any project. This dissertation evaluates the applicability of project planning and scheduling techniques used in erection of thermal power plants in TANESCO. Considering the complexity of erection projects, bar charts, that are techniques currently used in planning and scheduling, needed revisiting. The study aims at enhancing and facilitating better performance of erection projects in TANESCO, and similar projects in other organizations. Thus, other appropriate techniques and countermeasures to increase efficiency and effectiveness of existing techniques could be proposed. The objectives of the study were achieved through observations, interviews and use of questionnaires. It was established that, bar charts are not suitable tools for planning and scheduling complex projects. Thus, networks, incorporating aspects from other planning and scheduling techniques, such as CCPM, were confirmed as being superior tools for the purpose. Through the case study, it was revealed that project plans and schedules are regarded as merely formalities and not as working tools. The study demonstrated that planning and scheduling using networks reduce erection project duration to two and a half months from five, with a potential of saving Tsh 1.5 million every project team member saved from the project variable costs. In that context, it has been recommended that: culture for recognising project plans and schedules as working tools should be adopted; staff carrying out projects should be provided with relevant skills in project planning and scheduling and project team members be motivated by being given part of the saved variable costs as project allowances.
