GA FILE IS FROM GYPSUM ASSOCIATION FIRE RESISTANCE <br />DESIGN MANUAL GA-600-2015 21 ST EDITION, WASHINGTON <br />D.C. CONTRACTOR IS TO PROVIDE (2) COPIES OF THIS <br />MANUAL ON THE JOB SITE TO COORDINATE FIRE RESISTIVE <br />ATTACHMENT WITH SHEAR CONNECTORS AND SOUND <br />RATED ASSEMBLIES. CONTRACTOR SHALL REFER TO THE <br />"GENERAL EXPLANATORY NOTES" FOR ANY ALLOWED <br />DEVIATION FROM THE TESTED ASSEMBLY. <br />2. THESE DETAILS REPRESENT MINIMUM ARCHITECTURAL <br />REQUIREMENTS. IN SOME CASES THE STRUCTURAL <br />DRAWINGS WILL DETERMINE THE ACTUAL DIMENSIONS AND <br />CONNECTION METHODS, AND IN THOSE CASES WILL <br />GOVERN. IT IS THE CONTRACTOR'S RESPONSIBILITY TO <br />COORDINATE THE STRUCTURAL DRAWINGS WITH THESE <br />MINIMUM ARCHITECTURAL ASSEMBLIES. <br />3. STC & ICC TESTS ARE FROM GA MANUAL LISTED ABOVE, <br />OWENS-CORNING WALL & FLOOR ASSEMBLY GUIDE OR <br />FROM ICBO/ICC REPORTS. <br />4. SOUND TRANSMISSION REQUIREMENTS APPLY TO COMMON <br />INTERIOR WALLS, PARTITIONS AND FLOOR CEILING <br />ASSEMBLIES BETWEEN ADJACENT DWELLING UNITS OR <br />BETWEEN DWELLING UNITS AND ADJACENT PUBLIC SPACES <br />SUCH AS CORRIDORS, STAIRS AND SERVICE AREAS (2015 IBC <br />1207). <br />IBC SECTION 1207.2 AIR -BORNE SOUND: NOT LESS THAN <br />STC 50(45 IF FIELD TESTED). PENETRATIONS OR OPENINGS Il� <br />CONSTRUCTION ASSEMBLIES FOR PIPING, ELECTRICAL <br />DEVICES, RECESSED CABINETS, BATHTUBS, SOFFITS, OR <br />HEATING, VENTILATING OR EXHAUST DUCTS SHALL BE <br />SEALED, LINED, INSULATED OR OTHERWISE TREATED TO <br />MAINTAIN RATINGS. THIS REQUIREMENT SHALL NOT APPLY <br />TO DWELLING UNIT ENTRY DOORS, HOWEVER SUCH DOORS <br />SHALL BE TIGHT FITTING TO FRAME AND SILL. <br />IBC SECTION 1207.3 STRUCTURE -BORNE SOUND: NOT LESS <br />THAN IIC 50 (45 IF FIELD TESTED). <br />5. FLOOR/CEILING ASSEMBLY: STC 50 / IIC 50 MIN. <br />DEMISING WALL: STC 50 MIN. <br />CORRIDOR WALLS: STC 50 MIN. <br />6. WHERE SOUND RATED ASSEMBLIES INCLUDE THE USE OF <br />"RESILIENT CHANNELS", DIETRICH RC-1 DELUXE CHANNELS <br />SHALL BE USED. <br />7. SOUND RATED ASSEMBLIES - SOUND CONTROL: <br />SYSTEMS SHALL BE AIR -TIGHT. ITEMS THAT PENETRATE <br />THE GYPSUM BOARD SHALL NOT BE LOCATED BACK TO <br />BACK OR IN THE SAME STUD CAVITY. ANY OPENINGS FOR <br />FIXTURES OR PIPES SHALL BE CUT TO THE PROPER SIZE <br />AND SEALED. THE ENTIRE PERIMETER OF A SOUND <br />INSULATING SYSTEM SHALL BE MADE AIR TIGHT TO <br />PREVENT SOUND FLANKING. FLEXIBLE SEALANT OR AN <br />ACOUSTICAL GASKET SHALL BE USED TO SEAL BETWEEN <br />THE STC RATED SYSTEM AND ALL DISSIMILAR SURFACES <br />AND ALSO BETWEEN THE SYSTEM AND SIMILAR SURFACES <br />WHERE PERIMETER RELIEF IS REQUIRED. TAPING GYPSUM <br />BOARD WALL AND WALL -CEILING INTERSECTIONS PROVIDES <br />AN ADEQUATE AIR SEAL AT THESE LOCATIONS (ASTM E 497, <br />GA MANUAL SECTION III). <br />8. PROVIDE FIREBLOCKING IN ACCORDANCE WITH 2O15 IBC <br />SECTION 718.2 AS NOTED ON SHEET A040 <br />9. PROVIDE PROTECTION FOR THROUGH PENETRATIONS AND <br />MEMBRANE PENETRATIONS OF HORIZONTAL ASSEMBLIES <br />AND FIRE RATED WALL ASSEMBLIES IN ACCORDANCE WITH <br />2015 IBC SECTION 714 AS NOTED ON SHEET A040. <br />10. JOINTS INSTALLED IN OR BETWEEN FIRE RESISTIVE RATED <br />WALLS, FLOORS OR FLOOR/CEILING ASSEMBLIES AND <br />ROOFS OR ROOF/CEILING ASSEMBLIES SHALL BE <br />PROTECTED BY AN APPROVED FIRE-RESISTANT JOINT <br />SYSTEM IN ACCORDANCE WITH 2O15 IBC SECTION 715 AS <br />NOTED ON SHEET A040 <br />11. CONTINUITY OF FIRE RATED WALLS: <br />A. FIRE BARRIERS (IBC SECTION 707.5) AND SHAFT <br />ENCLOSURES (IBC SECTION 713.5): SHALL EXTEND FROM <br />THE TOP OF THE FLOOR/CEILING BELOW TO THE <br />UNDERSIDE OF THE FLOOR. ROOF SHEATHING, SLAB OR <br />DECK ABOVE AND SECURELY ATTACHED THERETO. AND <br />SHALL BE CONTINUOUS THROUGH CONCEALED SPACES. <br />B. SMOKE BARRIER (IBC SECTION 709.4): SHALL EXTEND <br />FROM THE TOP OF THE FOUNDATION OR FLOOR/CEILING <br />ASSEMBLY BELOW TO THE UNDERSIDE OF THE FLOOR. <br />ROOF SHEATHING, SLAB OR DECK ABOVE OR TO THE <br />FIRE- RESISTANCE RATED FLOOR/CEILING OR ROOF <br />CEILING ABOVE. <br />C. SMOKE PARTITIONS (IBC SECTION 710.4): SHALL FORM <br />AN EFFECTIVE MEMBRANE CONTINUOUS FROM OUTSIDE <br />WALL TO OUTSIDE WALL AND FROM THE TOP OF THE <br />FOUNDATION OR FLOOR/CEILING ASSEMBLY BELOW TO <br />THE UNDERSIDE OF THE FLOOR OR ROOF SHEATHING, <br />DECK OR SLAB ABOVE, INCLUDING CONTINUITY THROUGH <br />CONCEALED SPACES. <br />12. SEE "ENERGY CODE COMPLIANCE" NOTES ON SHEET CS01 <br />FOR INSULATION REQUIREMENTS. <br />13. ALL EXTERIOR GYPSUM SHEATHING BOARD (5/8" TYPE X) <br />SHALL BE DENS -GLASS GOLD OR EQUAL. <br />14. THE TERMS "GYPSUM WALLBOARD" AND "GWB" ARE <br />INTERCHANGEABLE. <br />15. WATER-RESISTANT GYPSUM WALLBOARD SHALL BE USED <br />AT ALL "WET LOCATIONS", I.E. @ BATHTUBS. <br />GA MANUAL GENERAL EXPLANATORY NOTES <br />A.
