The building is heated and cooled by a fan powered air volume system. Air is circulated through a system of vertical and horizontal duct work.

 

Structural:

Frame of the building is composed of steel columns, steel girders, steel beams, steel joists, and concrete slab on metal decking. Typical columns sizes are W12x60, W12x65 and W12x72. In most cases each column extends from the garage floor to middle of third floor where it is connects to and continued by smaller, lighter column. Typical joist (26k7) is supported by a steel girder, typically W24x68. All girder/joist to column connections are designed for a moment of 40 ft-kips to resist wind and seismic loads. All lateral loads are resisted by moment connections. The loads are transferred in this order: A four inch thick concrete slab on metal decking is held in place by steel joists; steel joists are connected to steel girders, girders are supported by steel columns, and columns stand on footings.

Movement inside the building is facilitated through a system of corridors, stairwells, and elevators that connect all tenant spaces to main lobby.
