It is unlikely that any two locations are going to have the exact same contingency plans. How much money do you have to spend, whats your expected recovery time, what % of staff will you get working and to what level. Under what situations would you move, do you have somewhere to go, too many questions unanswered to give you a good answer.
You need to talk to your boss and see what he wants to do then make your plans fit him/ his budget / his ability to make your plans happen.
