The ideology focussed planetary projects were removed some time ago. They still exist in the code, but are currently non-functioning. I don't know if there are plans to re-introduce them at a later time but for now this is it.
You could always have a go at editing the xml, but I'm unsure if the functionality of having projects unlocked through ideology still exists. You'd probably need to alter either the tech trees or ideology trees to unlock these projects also.
