<br /> <br />THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 078400-10 <br /> <br />4. Tool non-sag sealants immediately after sealant application and prior to the time <br />skinning or curing begins. Form smooth, uniform beads of configuration indicated or <br />required to produce fire-resistance rating, as well as to eliminate air pockets, and to <br />ensure contact and adhesion of sealants with sides of joint. Remove excess sealant <br />from surfaces adjacent to joint. Do not use tooling agents that discolor sealants or <br />adjacent surfaces or are not approved by sealant manufacturer. <br /> <br />C. Apply fire safing insulation, fire and smoke barrier caulk, and fire barrier wrap/strips according <br />to manufacturer's published installation details, directions, UL classified fire test data, and as <br />specified. <br /> <br />D. Gaps at Floor and Roof Edges Abutting Exterior Walls: <br /> <br />1. Install specified fire safing insulation continuously at each floor level above first floor <br />and at roof between back of precast concrete wall panels, concrete beams, and <br />columns of depth to achieve a 3-hour minimum fire resistance according to <br />manufacturer's directions. <br /> <br />2. Install fire stop insulation across exterior faces of columns at each floor level above <br />first floor including roof before erection of precast concrete wall panels. Secure <br />insulation in place across columns with suitable waterproof adhesive with flame <br />spread rating of 25 or less and with impaling clips at each side of columns. <br /> <br />3. Secure fire safing insulation to exterior faces of slab edges and beams with suitable <br />impaling clips spaced 24 inches o.c. and adhesive with flame spread rating of 25 or <br />less. <br /> <br />4. Provide fire safing insulation of required thicknesses as required to compress <br />insulation in joints. <br /> <br />5. Where gap is less than approximately 2 inches, bend clips slightly upward. Where <br />gap is less than approximately 1 inch, apply adhesive to sides of joint and tightly <br />pack safing insulation into joint. <br /> <br />6. Recess top surface of fire safing insulation 1 inch to receive fire and smoke barrier <br />caulk to provide 3-hour fire resistance according to manufacturer's directions. <br /> <br />7. Apply specified fire and smoke barrier caulk of required 1-inch uniform depth over <br />horizontal surfaces of fire safing insulation at each floor level above first floor and <br />roof. Smooth surface of caulk at exposed areas. <br /> <br />E. Floor and Roof Expansion Joints: <br /> <br />1. Provide 10 gage galvanized steel hat shaped wire support hangers at 8 inches o.c. <br />with bottom of wire near bottom of slab or beam. <br /> <br />2. Install specified fire safing insulation tightly packed in each suspended floor <br />expansion joint and roof expansion joint with insulation resting on hardware cloth <br />support and of depth to provide a 2-hour minimum fire resistance according to <br />manufacturer's directions. <br /> <br />3. Apply fire and smoke barrier caulk of required 1-inch uniform depth over horizontal <br />surfaces of fire safing insulation packed in suspended floor expansion joints. Fire <br />and smoke barrier caulk is not required in roof expansion joints.
