the building was designed with several features that enabled the store to function efficiently. for instance, ramps led from 38th and 39th streets to a receiving/delivery dock in the building's basement, obviating the need for delivery trucks to load and unload cargo on the street. additionally, the displays in the store's front windows were located on small elevators, which could be lowered into the basement whenever the displays had to be changed. there were several conveyor systems and dumbwaiters that could move products from the basement to the shipping department or customers. a packaging department was located on the eighth floor.
