<br />of gypsum drywall construction and an opening is provided for the box in the surface of
<br />that wall, the area of the opening may not exceed 16 square inches, unless the junction
<br />box is enclosed by a "5 -sided box" (See approved details),
<br />The aggregate area of all such junction boxes in a rated wall not enclosed by "5 -sided
<br />boxes" described above shall not exceed 100 square inches in 100 square feet of wall
<br />area as measured from floor to structural deck or rated membrane.
<br />Junction boxes with openings on opposite faces of rated walls shall have a horizontal
<br />separation of 24 inches as a minimum, regardless of box size, unless enclosed by "5-

<br />General Notes For Prioritv Walls
<br />1. Encase all vertical and horizontal ducts, pipes, conduits, panels, to match adjacent surfaces,
<br />Extend the furred spaces length of the wall between intersecting walls unless otherwise
<br />indicated. The contractor shall notify the Architect should conflicts arise between furring and
<br />casework, equipment or any other items. Provide access panels painted to match adjacent
<br />surfaces where access is required for valves, dampers or other devices requiring
<br />adjustment. Provide labeled access door where enclosure constitutes part of a fire rated
<br />assembly.
<br />2. The maximum allowable area of individual U.L, listed electrical back boxes permitted in
<br />frre/smoke walls is 16 square inches. With a maximum aggregate of 100 square inches per
<br />100 square feet of wall area. Back boxes on opposite faces of such walls shall be offset a
<br />minimum horizontal distance of 24 inches. Penetrations exceeding the allowable areas the
<br />devices shall be set in a furred space in front of the fire or fire /smoke wall as described in
<br />notes above or provided with a five -sided enclosure as described below.
<br />3. Items recessed in corridor, smoke or fire walls such as recessed toilet accessories, fire
<br />extinguisher and/or hose cabinets, fire alarm signal boxes, electrical and signal cabinets, or
<br />other back boxes which exceed 16 square inches shall be installed in a five -sided enclosure
<br />as indicated on the drawings. Where depth of box exceeds wall thickness, provide framing
<br />as required to accommodate depth as described above.
<br />4. Where ducts, pipes, conduit, bar joists, beams or any other materials penetrate a fire rated
<br />wall or partition, openings shall be tightly sealed. Annular openings in CMU walls shall be
<br />filled with grout. Do not cover penetrations of CMU walls with drywall. Penetrations in metal
<br />stud partitions shall be constructed with 20 ga. Galvanized runner channel sill and header
<br />secured to metal studs, with the space around the perimeter of the penetrating object
<br />packed tightly with compressed mineral fiber insulation. Insulated pipes shall be sleeved
<br />with foam glass insulation. Annular opening between sleeve and pipe shall be sealed with
<br />approved fire and smoke retardant sealer. Sleeves shall extend a maximum of 2" beyond
<br />faces of wall. Refer to partition details and mechanical drawings.
<br />5. Provide proper clearances at fire dampers between the sleeve and stud framing members.
<br />Fire damper sleeves shall be installed and secured in accordance with SMACNA standards.
<br />Fire dampers shall be installed in the plane of the rated assembly.
<br />6. Low voltage wiring which penetrates a smoke or fire /smoke wall Shall be sleeved with
<br />conduit extending not more than 2 inches either side of the wall and securely anchored to
<br />prevent slipping through the wall or damaging the drywall. Remaining openings in the
<br />conduit sleeve shall be filled with tightly compressed mineral fiber safeing insulation and
<br />sealed with acoustical sealant. It is the responsibility of the general contractor to assure
<br />coordination of installation of such systems between vendors and subcontractors. The
<br />contractor shall assure that penetrations for utilities are made with the utmost care and
<br />minimum of damage to the integrity of all partitions and walls, Sleeves and conduit shall be
<br />installed prior to running cables.
<br />7. Furnish access panels in walls and non - accessible ceilings where service or adjustment to
<br />mechanical, plumbing or electrical equipment is required, and at intervals not to exceed 30
<br />feet in non - accessible ceilings or fire membranes adjacent to fire and fire /smoke walls.
<br />Where access panels occur in rated assemblies they shall bear a label rating equal to that
<br />of the assembly. Access panels in gypsum wallboard membranes above non - accessible
<br />ceilings shall be aligned to permit access and shall be sized to permit positioning of a step
<br />ladder through the access panel in the ceiling. Rated access panels in ceilings and
<br />membranes shall be supported from the structure, not the ceiling framing.
<br />8. Coordinate installation of plumbing, vent stacks and conduit to permit installation of
<br />recessed toilet accessories, fire extinguisher cabinets and other recessed equipment.
<br />Where such items are recessed in corridor, smoke or fire /smoke walls they shall be installed
<br />in a five -side enclosure as described above.
<br />9. All wood blocking within the building envelope shall be pressure treated. Isolate salt treated
<br />wood from metal framing with 15# felt and use corrosion resistant fasteners to minimize
<br />galvanic corrosion.
<br />10. Provide acoustical sealant to prevent passage of smoke at penetrations of either
<br />smoke - resistant or fire /smoke partitions. Where fire- safing is used, the acoustical sealant
<br />shall be required only on one side of wall.
<br />Fire Protection Criteria
<br />1. One hour rated corridor partitions shall extend to underside of floor or roof deck.
<br />2. Smoke resistive partitions shall extend to underside of floor or roof deck or underside of
<br />gypsum wallboard membrane frreskin or to 4" above ceiling - Refer to Wall Rating Legends,
<br />3. Smoke barrier partitions shall be constructed uninterrupted, tight from back of exterior wall
<br />and from floor slab to underside of floor or roof deck.
<br />4. Firestopping shall be provided at the plane of the gypsum wallboard membrane or rated
<br />ceilings all penetrating partitions, exterior stud walls and furred spaces.
<br />5. All backboxes, panels, valve boxes, toilet accessories and other recessed items in excess of
<br />sixteen square inches, which are recessed in fire rated walls shall be protected with a five
<br />sided enclosure equal to the rating of the wall.
<br />6. The contractor shall construct all fire rated assemblies in the following order of priority:
<br />Four Hour Fire walls
<br />Three Hour Fire walls
<br />Two Hour Fire walls
<br />One Hour Fire walls
<br />Gypsum wallboard horizontal fire membrane
<br />One hour rated partitions
<br />Smoke resistive walls
<br />Non -rated interior partitions
<br />7. The Contractor shall provide signage above the ceiling spaced at 10' O.C. indicating the
<br />rated partition type and to "PROTECT ALL OPENINGS ". Signage letters shall be 3" high in
<br />a dark red color and be placed on both sides of priority walls along their entire length.
<br />General Notes
<br />1. All corridor walls are 1 hour rated unless noted otherwise. Refer to Al series for details.
<br />2. See the index sheet for additional notes which also apply to this Life Safety plan.
