For a planet, you only get the base rate if you don't have a spaceyard.

So when building a level one spaceyard, you are effectively buying only the ability to build ships.

The 3600 build rate would be from the following:
2k for the yard, +80% for bonuses = 3600

(25%(H.I.)+25%(SY skill)+30%(population) = 80% bonus)
