The AI will build Intel facilities on 3 types of colonies: Intel, Research & Intel, and Military. However, the problem is that often these mixed colonies get assigned to non-breathable colonies with insufficient space so they don't always see an Intel Center.
No worries though, I'll bump up the Intel Compound priority a bit and you'll see some more Intel points produced.

I was able to remedy my problem with the new treaty proposal scheme and it seems to be working out OK now. Depending on a few factors like anger or the number of wars its in, the AI will make packages for the following treaty "classes": Partnership, Military Alliance, Cooperation, Trade & Research, Trade, Non-Aggression, Non-Intercourse, Protectorate, and Subjugation. Some of the terms are "hard-coded", others are allowed to vary in their stipulations, and lastly some terms are randomly thrown in.
Currently, counter proposals and stuff work under the old scheme. I doubt I'll bring them up to snuff in this patch to the new system but if it isn't too complicated then maybe.

I'm also adding a Bombardment Ship for the AI to use in its fleets. This guy will generally be designed to soften up the defenses of colonies with planetary weapons - sort of a countermeasure to deal with the stronger planet defenses.

I should have a v0.99 of the mod ready for tomorrow night.
