Masonry Partitions
Construction: Normal-weight concrete masonry units, typically 8-inch width, ASTM C270 Type S mortar, reinforced with
vertical rebar and with horizontal truss-type reinforcing in every other course. Partitions will run from the floor to the
underside of steel floor or roof deck above, and will be restrained from lateral movement at the top.
Locations: Stage, locker rooms and connecting corridors, kitchen, mechanical rooms, main electrical room, fire
pump room, elevator shafts and elevator machine rooms, receiving area, and toilet cores.
Fire-Rated Partitions: Where a fire-rating is required, masonry partitions will be constructed to conform to a specific U.L.
design. Specific locations will depend upon the final building design, but the following are probable locations:
2-hour rated construction around elevator shafts and elevator mechanical room, building mechanical room, main
electrical and emergency electrical rooms, fire-pump room. Egress stairs where necessary.
1-hour rated partitions enclosing the kitchen and the receiving area.

Gypsum Board Partitions
Typical Gypsum Board Partitions: 5/8 inch thick gypsum board on 3-5/8" deep, 20 gauge steel studs spaced 16 inches
on center. Screw gypsum board to studs. Partitions typically extend full height from floor to underside of deck above.
Non-rated storage rooms, rooms other than teaching spaces
Fire-Rated Gypsum Board Partitions: As above, but conforming to a specific U.L. design, and constructed with Type
X/Fire Core gypsum board. Specific locations will depend upon the final building design, but the following locations are
probable:
2-hour rated construction around emergency electrical closets and utility shafts. Possibly the egress stairs if
Trespa panel facing Add-Alternative is selected.
Acoustical Partitions (Type 1): Typical Gypsum Board partition with acoustical insulation inside the wall and acoustical
caulking at
