Is that door bolted on from the inside, or is the frame grouted into the walls?
For banks, our specification is usually welding of frame to the precast vault panels, then non-shrink grout at 2x concrete strength. Additionally, we always call for the frame & door to be set proud of the wall 9/16" so that finished drywall can be slipped under (saves masking the prefinished doors).
Oh, and mke sure you put a door stop in, and one that stops the door before the operating handles hit the wall. Not a terrible idea to have a hold-open, too.
