Hafod Eryri Project: Gantt Chart, WBS, and Budget Analysis

This project management assignment analyzes the Hafod Eryri project, covering various aspects of project planning and execution. It begins with the calculation of weighted expected time durations for different activities and uses this data to create a Gantt chart and a Work Breakdown Structure (WBS). The assignment then reflects dependencies between tasks and assigns resources, materials, and facilities. A critical path analysis is performed, and methods for resolving resource overload are presented. The assignment also includes a detailed budget breakdown, including total costs and a cash flow analysis. The document incorporates figures illustrating the Gantt chart, WBS, dependencies, resource allocation, critical path, resource leveling, and cash flow. A bibliography of relevant project management literature is also included.
