<br />1. Floor and Ceiling Runners — "J"-shaped runner, min 4 in. deep with unequal legs of 1 in. and 2 in., fabricated
<br />from 20 MSG galv steel. Runners positioned with short leg toward finished side of wall. Runners attached to
<br />structural supports with steel fasteners located not greater than 2 in. from ends and spaced no more than 24 in.
<br />OC.
<br />2, Vertical Runners — "J"-shaped runner, min 4 in. deep with unequal legs of 1 in. and 2 in., fabricated from 20
<br />MSG galv steel. Vertical runners positioned at each end of the wall with short leg toward finished side of wall.
<br />Runners attached to structural supports with steel fasteners located not greater than 2 in. from ends and spaced
<br />no more than 24 in. OC.
<br />3. Steel Studs — "C-H" -shaped studs, min 4 in. deep, with 1-1/2 in. wide flanges, fabricated from 20 MSG galv
<br />steel. Installed horizontally, with the "C" section of the studs facing down, friction fitted in the vertical "J"-shaped
<br />runners resting upon 2 by 2 in. by 20 ga. steel angles which are fastened to the side "J"-shaped runners. Studs cut
<br />to lengths to allow a 3/8 to 1/2 in. gap at each end of the wall, and spaced vertically 24 in. or 600 mm OC. As an
<br />option, the studs may be screw attached to the side "J"-shaped runners. A total of four 112 in. long pan -head steel
<br />screws are to be installed, one at each end of the stud on each side of the wall.
<br />4. Gypsum Board* —1 in. thick gypsum wallboard liner panels, supplied in nom 24 in. or 600 mm (for metric
<br />spacing) widths. Panels cut to lengths 1 in. less than the width of the wall. Once between the vertical "J"-shaped
<br />runners, the panels are centered to split equally at each end the 1 in. gap. Installed horizontally, with the long
<br />edges inserted in the "H" section of the "C-H"-shaped studs. The top edge of the liner panel shall be cut 1 in. less
<br />than opening height to allow installation past the 1 in. leg of J-runner. Free edge of panels attached to the long leg
<br />of the top and bottom "J" -runners with 1-5/8 in. long Type S or S-12 steel screws spaced no more than 12 in. OC.
<br />The width of the wall is limited to the length of the liner panels (no butt joints in the liner panels).

<br />5. Gypsum Board* — 518 in. thick, 24 to 54 in. wide gypsum panels applied vertically in one (1-hr system) or two
<br />(2-hr system) layers. Vertical joints between panels need not be backed by framing. Vertical joints between layers
<br />staggered a minimum of 12 in. Horizontal joints centered over studs and staggered a minimum of 24 in. in adjacent
<br />courses and 24 in, between layers. 1-Hr System: Single layer attached to studs and vertical and horizontal
<br />"J"-shaped runners with 1 in. long Type S or S-12 steel screws spaced 8 in. OC. Joints covered with paper tape
<br />and joint compound. Exposed screw heads covered with joint compound. Joint tape and compound may be
<br />omitted when square edge panels are used. 2-Hr System: Base or inner layer attached to studs and vertical and
<br />horizontal "J"-shaped runners with 1 in. long Type S or SA 2 steel screws spaced 12 in. OC. Outer or face layer
<br />attached to studs and vertical and horizontal "J"-shaped runners with 1-5/8 in. long Type S or S-12 steel screws
<br />spaced 8 in. OC. Outer layer joints covered with paper tape and joint compound. Exposed screw heads covered
<br />with joint compound. Joint tape and compound may be omitted when square edge panels are used.

<br />2. Mortar - Blocks laid in full bed of mortar, nom. 3/8 in. thick, of not less than 2-1/4 and not more than 3-1/2
<br />parts of clean sharp sand to 1 part Portland cement (proportioned by volume) and not more than 50
<br />percent hydrated lime (by cement volume). Vertical joints staggered.
<br />3. Portland Cement Stucco or Gypsum Plaster - Add 1/2 hr. to classification if used. Where combustible
<br />members are framed in wall, plaster or stucco must be applied on the face opposite framing to achieve a
<br />max. Classification of 1-1/2 hr. Attached to concrete blocks (Item 1).
