If I can remember, a harbour requieres to have a dock, and the dock to have a pier. To have a pier, your city must stay near a river tile at the settle point (not if you build your city from other tile to river - they call this sneak).
It is the same for the logging camp: only allowed if a forest tile is near the settle point. No sneak on this, too.
The wonders, like the Great Mill, can only be chosen when no other faction has started to build it. Once a faction starts it, then disappear from build options.
The brewery, I can't remember. I think it can only be built in a Town, not in a fortress or conclave.
Check the prerequisites in the Tech Tree, the information is there...
