Andy, use ship with space yard to build your BS, then once its built both your BS and shipyard ship can both build at the same time at same location, also build BS over your primary planets and use those for shipyards, this frees up space on your planets for better facilities and if you have several, you can build multiple ships at the same location close to the same time frames. Remember they are expensive to maintain, so pick your locations carefully, also by having 2 or more together you can upgrade them 1 at a time without taking away all your defense.

just some ideas mac
