The renovation of Alumni Hall will involve complete removal and replacement of interior floors. Because the floors are tied into the walls, temporary steel structures — not unlike the “flying buttresses” in Gothic cathedrals — will support the east and west walls for the time between removal and replacement of the floors. Above, footings were excavated for concrete bases of the steel buttresses.
