Project Management Concepts and Applications

The assignment presents a detailed case study of a construction project, outlining its various stages, tasks, and responsibilities. It employs Gantt charts to visualize the project timeline and emphasizes the importance of effective communication, risk management, and stakeholder engagement throughout the project lifecycle. The document delves into specific project management techniques, such as resource allocation, task scheduling, and progress monitoring, illustrating their application in a real-world scenario.
