If he ever becomes open to a smaller school (and he may not!) I think he is a plausible candidate for the Johnson Scholarship at Washington and Lee University.
It does not tick all his boxes – size, and I believe no Construction management – but it does tick a lot: very collegial (between the Speaking Tradition and the Honor Code (taken very seriously), and a good Earth/Geoscience Dept. It’s one of the few LACs with a business school. Can’t speak to urban planning but a friend of my sons is doing that (and is also a Johnson Scholar).
So, it’s not a safety, but if he becomes ok with the size, it’s a pretty amazing opportunity. I should add that VMI is right next door, so there are around 4,000 college students in Lexington.
