Taken a few days ago. They are making good progress on this project.

I wonder how many casual observers think those limestone blocks are hand-laid in place. I know that is what I had always assumed was the way these modern classics were built.

As you can see in the photos; the entire facade is composed of ‘prefabricated panels’ that are hoisted into place, then bolted to brackets on the concrete slabs.

Modern construction construction technology is amazing, and always fascinating to watch. 🤩
