The following ceilingsystem(s) is/are part of the scope of this project:Manufacturer's Name: Certainteed Ceilings.Product Evaluation Report Type and Number:ICC-ES Evaluation Report ESR-3336.Manufacturer's Model Number - Main Runners:9/16" Elite Narrow Stab System-ES 12-12-1915/16" Classic Stab System-CS 12-12-20Manufacturer's catalog number - Cross Runners:9/16" Elite Narrow Stab System-ES 2-12-19-ES 4-12-1915/16" Classic Stab System-CS 2-12-20-CS 4-12-201.04 Seismic Wall Clip: Manufacturer's ModelNumber CertainteedCTSPC-21.05 Ceiling panels shall not support any lightfixtures, air terminals or devices.1.06 For ceiling installations utilizing acousticaltile panels of mineral or glass fiber, it is notmandatory to provide ¾” clearance between theacoustical tile panels and the wall on the sides ofthe ceiling which are free to slip. For all otherceiling panel types, provide ¾” clearancebetween the ceiling panel and the wall on thesides of the ceiling free to slip.·MATERIALS:2.01 Ceiling wire shall be Class 1 zinccoated (galvanized) carbon steel conforming toASTM A641-09a. Wire shallbe #12 gage (0.106” diameter) with soft temperand minimum tensile strength = 70 ksi.2.02 Galvanized sheet steel (including that usedfor metal stud and track compressionstruts/post) shall conform to ASTM A653-11, orother equivalent sheet steel listed in Section A2.1of the North American Specification for theDesign of Cold-Formed Steel Structural Members2012, including supplement dated 2014 (AISIS100-12). Material 43 mil (18 gage) and lightershall have minimum yield strength of 33 ksi.Material 54 mil (16 gage) and heavier shall havea minimum yield strength of 50 ksi.2.03 Electrical metallic tube (EMT) shall be ANSIC80.3/UL 797 carbon steel with G90 galvanizing.EMT shall have minimum yield strength (Fy) of30 ksi and minimum ultimate strength (Fu) of 48ksi.·ATTACHMENT OF HANGER ANDBRACING WIRES:3.01 Separate all ceiling hanger and bracingwires at least six (6) inches from all unbracedducts, pipes, conduit, etc.3.02 Hanger and bracing wires shall not attach toor bend around obstructions including but notlimited to: piping, ductwork, conduit andequipment.3.03 Hanger wires that are more than one(horizontal) in six (vertical) out of plumb shallhave counter-sloping wires.3.04 Slack safety wires shall be consideredhanger wires for installation and testingrequirements.3.05 Hanger and bracing wire anchorage to thestructure shall be installed in such a manner thatthe direction of the anchorage aligns closely withthe direction of the wire. (e.g. bracing wireceiling clips must be bent as shown in the detailsand rotated as required to align closely with thedirection of the wire, screw eyes in wood must beinstalled so they align closely with the directionof the wire, etc.)·FASTENERS AND WELDING:4.01 Sheet metal screws shall comply with ASTMC1513-10, ASME B18.6.4-98 (R2005).Penetration of screws through joined materialshall not be less than three exposed threads.4.02 Expansion anchors shall be: [Notapplicable to project]4.03 Power-Actuated Fasteners shall be: [Notapplicable to project]4.04 If not otherwise specified in the evaluationreport, power-actuated fasteners installed insteel shall be installed so the entire pointed endof the fastener is driven through the steelmember.4.05 Power-actuated fasteners in concrete arenot permitted for bracing wires.4.06 Concrete reinforcement and prestressingtendons shall be located by non-destructivemeans prior to installing post - installed anchor.4.07 Welding shall be in accordance with AWSD1.3 using E60XX series electrodes.·TESTING: All field testing must beperformed in the presence of the projectinspector.5.01 Post-installed anchors in concrete used tosupport hanger wires shall be tested at afrequency of 10 percent. Power actuatedfasteners in concrete shall be field tested for 200lbs. in tension. All other post-installed anchors inconcrete shall be tested in accordance with CBCSection 1910A.5.5.02 Post-installed anchors in concrete used toattach bracing wires shall be tested at afrequency of 50 percent in accordance with CBCSection 1910A.5.·LIGHT FIXTURES:6.01 All light fixtures shall be positively attachedto the ceiling suspension systems by mechanicalmeans to resist a horizontal force equal to theweight of the fixture. A minimum of two screwsor approved fasteners are required at each lightfixture, per ASTM E580, Section 5.3.1.6.02 Surface-mounted light fixtures shall beattached to the main runner with at least twopositive clamping devices. The clamping deviceshall completely surround the supporting ceilingrunner and be made of steel with a minimumthickness of #14 gage. Rotational spring catchesdo not comply. A #12 gage slack safety wireshall be connected from each clamping device tothe structure above. Provide additional supportswhen light fixtures are eight (8) feet or longer orexceed 56 lb. Maximum spacing betweensupports shall not exceed eight (8) feet.6.03 Not used.6.04 Light fixtures weighing less than or equal to10 lb. shall have a minimum of one (1) #12 gageslack safety wire connected from the fixturehousing to the structure above.6.05 Light fixtures weighing greater than 10 lb.but less than or equal to 56 lbs. may besupported directly on the ceiling runners, butthey shall have a minimum of two (2) #12 gageslack safety wires connected from the fixturehousing at diagonal corners to the structureabove.Exception: All light fixtures greater thantwo by four feet weighing less than 56 lbs.shall have a #12 gage slack safety wire at eachcorner.6.06 All Light fixtures weighing greater than 56lb. shall be independently supported by not lessthan four (4) taut #12 gage hanger wires (one ateach corner) attached from the fixture housing tothe structure above or other approved hangers.The four (4) taut #12 gage wires or otherapproved hangers, including their attachment tothe structure above, shall be capable ofsupporting four (4) times the weight of thefixture.·SERVICES WITHIN THE CEILING:7.01 All flexible sprinkler hose fitting mountingbrackets, ceiling-mounted air terminals or otherservices shall be positively attached to the ceilingsuspension systems by mechanical means.Screws or approved fasteners are required. Aminimum of two attachments are required ateach component.7.02 Ceiling-mounted air terminals or otherservices weighing less than or equal to 20 lb.shall have one (1) #12 gage slack safety wireattached from the terminal or service to thestructure above.7.03 Flexible sprinkler hose fittings,ceiling-mounted air terminals or other servicesweighing more than 20 lb. but less than or equalto 56 lb. shall have two (2) #12 gage slacksafety wires (at diagonal corners) connectedfrom the terminal or service to the structureabove.7.04 Flexible sprinkler hose fittings,ceiling-mounted air terminals or other servicesweighing more than 56 lb. shall be supporteddirectly from the structure above by not less thanfour (4) taut #12 gage hanger wires attachedfrom the terminal or service to the structureabove or other approved hangers.·OTHER DEVICES WITHIN THECEILING:8.01 All lightweight miscellaneous devices, suchas strobe lights, occupancy sensors, speakers,exit signs, etc., shall be attached to the ceilinggrid. In addition, devices weighing more than 10lbs. shall have a #12 gage slack safety wireanchored to the structure above.
