This 3 story granite building is constructed of composite steel.  Its unique angled shape is composed from a complicated grid of beams.  Deep heavy beams are used to span over the column free lobby.  The entrance is a 4 story glass atrium framed out of structural tubing.  Numerous functional and loading conditions had to be considered in the design:  lobby and offices, roof top terraces, high density storage, vault walls and roofs to name a few.  Another unique feature is that a portion of the second and third floors span over a 6 lane drive-thru facility.
