of the columns and the header beams are connected to the racks by
open web bar joists that stabilize the tops of the columns
against wind loads and maintain rigidity. These columns are
supported at the bottom by foundation walls, which vary in height
to conform to the outside grade. The foundation walls of the
Reserve Facility are poured-in-place, reinforced concrete,
consisting of continuous footings and retaining walls. The wall
panels are assembled from one end of the Reserve Facility to the
other. Each panel is screwed to the girts with a reinforcing
clip. All the joints are caulked between the panels and on the
top and bottom girts. The ends and exposed edges of panels are
finished with a preformed metal trim. Within the wall system are
metal ventilation louvers, a 12-foot-wide by 14-foot-high rollup
door, and several hollow metal swing doors and frames.
The Reserve Facility is covered by a roof that is directly
connected to and supported by the racks. The Reserve Facility's
roof consists of a 1.5-inch-deep corrugated metal deck supporting
rigid insulation and a waterproof membrane roof. The roof
membrane and the rigid insulation are held in place with stone
ballast. Special flashing and trim pieces are used to terminate
the membrane at mechanical equipment penetrations and around the
perimeter of the roof. The metal deck is supported by beams that
run across the top of the supporting rack posts. At the north
and south ends of the Reserve Facility, the roof, which includes
the deck, insulation, and membrane, is supported by open web bar
