Project plan that will allow production to continue

You are the Operations Manager and the CEO has tasked you to come up with a project plan for moving the Shipping Department to the new addition and expanding the Production Department into Shipping’s old space. Your guidance is, “come up with a plan to shift move Shipping to the new addition and expand production capacity using Shipping’s current space with minimal impact to operations. We need to meet our contractual deadlines.” You are told that you will be able to buy new machines for production’s increasing capacity, but the current machines in the production department will still be used. In other words, you can’t throw away the existing machines in production.
Develop a project plan that will allow production to continue while the movement of machines and staff into their new locations is taking place. The plan needs to list assumptions, constraints, and a network diagram for the move. Also, identify the critical path in your plan and its length in days.
