To create an effective project management plan for your new expansion, it's essential to organize tasks, identify dependencies, construct a network diagram, and determine the critical path accurately. Let's break down these components: Task List with Durations Task 1: Initial Planning and Approvals - 10 days Task 2: Site Preparation - 15 days Task 3: Foundation Laying - 12 days Task 4: Structural Construction - 30 days Task 5: Utility Installations - 18 days Task 6: Final Inspections and Handover - 10 days Dependencies Task 2 (Site Preparation) can only start after Task 1 (Initial Planning and Approvals) is completed. Task 3 (Foundation Laying) requires the completion of Task 2. Task 4 (Structural Construction) depends on the completion of Task 3. Task 5 (Utility Installations) can start only after Task 4 is completed. Task 6 (Final Inspections and Handover) can begin after Task 5 is finished. Network Diagram The network diagram visually represents the sequence and dependencies of tasks: Task 1 -> Task 2 -> Task 3 -> Task 4 -> Task 5 -> Task 6 Each arrow indicates a dependency where the succeeding task cannot start until the preceding task is completed. Critical Path The critical path is the longest path through the project's network diagram and determines the project's shortest possible duration. It also represents the tasks where any delay directly impacts the project's completion. Using the provided task durations, the critical path is calculated as follows: Task 1: 10 days Task 2: 15 days Task 3: 12 days Task 4: 30 days Task 5: 18 days Task 6: 10 days Adding these durations together gives us: 10+15+12+30+18+10=95 days10+15+12+30+18+10=95 days The preliminary calculation of 85 days seems to have missed some task durations or dependencies. According to the correct critical path calculation outlined above, the critical path actually spans 95 days. Conclusion Project Span: 95 days on the critical path. Critical Path Tasks: Tasks 1 through 6, in sequence, must be carefully managed to prevent project delays. Additional Considerations: It's advisable to include buffer days to handle unforeseen issues or delays, ensuring that the project's objectives are still met without impacting the overall timeline. By adhering to this structured approach and keeping a diligent eye on the critical path, you can effectively implement the project management plan, minimizing operational downtime and aligning with strategic objectives.
