FIG. 32.—LONGITUDINAL SECTION OF A FREEZER AND STORAGE ROOM.
Area and Division.
—The plant shown in [Figs. 31], [32] and [33] has a large ground area and is a non-sprinkled risk. This building has a frontage of 230 feet by 130 feet depth. To avoid an insurance area charge for too large floor areas, and because of a desire to carry several temperatures, the building was subdivided into three sections, A, B and C, by putting in fire walls. It was designed to have Section “C” subdivided into two halves, permitting the maintenance of two classes of low temperature. Section “B” was set aside primarily for carrying eggs and apples and thoroughly isolated. Section “A” was treated in like manner to Section “C,” except that provision was made for the division wall, which was not put in at time of construction. Illustrating the design is a general [floor plan] of the premises together with a [longitudinal section] drawing and a [cross section] drawing of Section “C.”

Receiving and Discharging.
—Referring to the [plan], attention is drawn to the three sections. Ingress and egress have been provided by railroad track at one end of Section “A” and double track with platforms on each side connected at end. Twin elevators with stairs are located within a continuous vestibule and the center section can be served from either elevator and stairs in either vestibule. The corner stairs in Sections “A” and “B” were demanded by the City Building Department, but not necessary to the operation of the plant.
Insulation Lines.
—Referring to the [longitudinal section] observe the twin columns, twin girders on each floor level, the inner carrying the floor construction and the outer the curtain walls. Notice the inlay of insulation. The outer walls entirely enclose the concrete skeleton, making the brick work continuous and sightly.
