ALCOA CORPORATE CENTER, Pittsburgh PA 1994 - 1998.




Checker-skin at south-east corner. See full elevation to observe the multiple scales of the skin-glass checkers. (July 1997)




View of the wrapped serpentine from the south-east on the 9th Street Bridge. See also the bird's eye view of this serpentine office block from north-east. (July 1997)




View of building from north-east showing building layering: the "serpentine office block" (here on the left, only the north-east corner visible), the "core-building" (the tall, thin, orthogonal-bar "vertical-slab"), and in the foreground, a profile of "blind-walls," the "skyline-silhouette," which includes the service tower near the north-east corner.

Across the street from this north-east tower is a small brick building by Frederick Osterling 1917, the only survivor of the "missing tooth" urbanism of this area, not an untypical condition of the 20th.C North-American cities. The parking lots surrounding this lone building is the existing -- "as found" -- conditition. (July 1997)
