Nope...I'm all in for using precast. People generally don't have a clue about precast or how it works so any exposure we get is all the better

That's real easy to say when you are not the one paying the bill.
Ok then let’s clear this project up then. This project appears to be fabricated out of what we call architectural precast. That means no gray concrete is used in the visible exterior. So we are talking colored concrete that will not be painted at anytime. I also suspect that an acid etching has been applied to the surface of the panels to give it some texture when you touch it.
So far what I see from these pictures is absolutely master craftsmanship of the work. To build the forms with such deep relief and moldings takes a true quality producer. You guys really need to educate yourself about the precast used in this project. There is NOTHING cheap about what you have seen so far. You may not like the style but it looks like high quality work and I can certainly give it some respect.

I've heard several stories where limestone actually came out CHEAPER than precast concrete, but these were all on small projects. Perhaps the economies of scale make precast cheaper in large quantities?

Yes....it really is that expensive. Natural stone is tremendously labor intensive. I can't imagine any project that puts limestone cheaper then precast. We have in the past attached granite to the face of our projects to get the best of both worlds.

Also, what about attachment systems and the labor of installation? I can't imagine that precast is much lighter than limestone.

Precast is still better here because you just can't haul a 10x40ft piece of limestone around on a truck without the likelyhood of it breaking. Precast is also used as a structural member in lots of cases. In this day and age limestone would only be used as a skin and would not carry any loads of the building.
