Infrastructure is comprised of a limited number of parts repeated to form a rhythmic system. The building's rhythm of long and short bays becomes a metronome by which the train passenger can measure their change in velocity as the train enters and leaves the station. The rhythm continues outside the building envelope as a pattern of trees and retention ponds. Infrastructure is built on an installed base. The buildingís base deflects to accommodate seating, support the structure, and provide access to the trains. It serves as a socket into which artifacts from the Henry Ford Museum can be placed for display.

The structural cores began as heavy concrete pieces. Later, the cores became thinner and lighter. Now, their mass is not as important as their effect on space. They allow light to enter the building, creating diffuse light and patterns of shadows as the sun plays across the structures and ceilings.
