The CAST Tech high school in San Antonio Texas is a special school. Supported by the local businesses, the curriculum is designed to produce graduates armed with the tech skills that will almost assuredly get them a job and/or set them up for success in their secondary education. 
The building chosen wasn't an obvious one. While it is downtown, and close to the companies looking to support and later hire the students, the building is an old vocational school built in the 30s. 
On top of that, the entire schedule for demo and reno was a matter of months. It had to be ready when the school year started. So they really needed to think about building the interiors in a very different way. A way that would continue to support them as teaching methods and technologies changed over the years. 
Everyone, but the designer, was skeptical that integrated prefab would do the trick.
