			1.	Lay out as shown in construction drawings. Secure J Track as perimeter framing and plumb to ceiling, floor and sides. Attach with suitable fasteners, spaced not more than 24 inches (610 mm) on centers. Apply a bead of sealant to the perimeter.
			2.	Preplan the stud layout 24 inches (610 mm) on center and adjust the spacing at either end so the end studs will not fall closer than 12 inches (305 mm) from the end.
			3.	Erect the first 1-inch (25.4 mm) shaft wall liner panel, cut 3/4 inch (19.0) less than the total height of the framed section. Plumb the panel against the web of the J Track and bend out tabs in J Track to secure panels in place.
			4.	Insert C-T Stud, cut 1/2 inch (19.1 mm) less than the overall height, into the top and bottom J Tracks and fit tightly over the previously installed 1 inch (25.4 mm) panel. Allow equal clearance between top and bottom J Track.
			5.	Install the next 1-inch (25.4 mm) shaft wall liner panel inside the J Tracks and within the tabs of the CT stud.
			6.	Progressively install succeeding studs and panels as described above until the wall section is enclosed. The final panel section may be secured with tabs from the J Track at 12 inches (305 mm) on center.
			7.	Where wall heights exceed the standard or available length of shaft wall liner panels, the gypsum panels may be cut and stacked with joints occurring within the top or bottom third points of the wall. Joints of adjacent panels should be alternately staggered to prevent a continuous horizontal joint.
			8.	For doors, ducts or other large penetrations or openings, install J Track as perimeter framing. Use 20 gauge, 0.0329 inches (0.83 mm) track with a 3 inches (76 mm) back leg for elevator doors and block cavity with 12 inches (305 mm) wide gypsum filler strips for doors exceeding 7-foot (2 m) height.
	3.3	PROTECTION
		A.	Protect installed products until completion of project.
		B.	Touch-up, repair or replace damaged products before Substantial Completion.
