Building the Legionfall Command Center

I’m not sure if this topic belongs here, but our Command Center was destroyed and now it needs to be rebuilt. It seems to be a slow process with only a few players being there to contribute war supplies. How long does it take for the Command Center to be rebuilt, or how many war supplies does it need before it can be built? I’ve dropped a few hundred war supplies at a time into contributing and it doesn’t make a blip on the meter so I’m not sure if that makes a difference.
