Kirk Anderson, Vice President of P.J. Hoerr, construction contractor for the renovation of Alumni Hall, talks to alumni at Homecoming 2013 about the renovation process.
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.
