I think most concrete tilt up construction was probably done since the 1960's, so the door spacing would be set up for 50-60 foot cars or even longer. I mention this because the meat companies like Swift, Armour Star, Rath, etc continued to use 36 foot ice bunker cars long after the railroads went to 40 foot and eventually to 50 foot as standard refrigerator cars because their packing plants were set up with door spacing for 36 foot cars, and they didn't want to change their buildings.
If a modern building has multiple doors and is designed for 89 foot box cars, and they receive loads in 50 foot cars, the car can be uncoupled and spotted to fit the doors. If multiple doors are spaced for 50 foot cars, and they receive a 60-89 foot car, they loose one or more door spots.
