Keep in mind that embedding the nuts in the concrete tunnel wall so that they were in the correct spot to hang the panels from would be VERY labor-intensive.  What I really don't understand is why the suspended panels needed to be concrete at all?  Wouldn't something much lighter like fiberglass work just as well?

The hell of it is, that if they had used the correct epoxy, the "gluing" process would have been perfectly acceptable for this application.  The reason the panels were pulling out what that the installer used the wrong epoxy, not because they were epoxied instead of bolted.
