17、nst the spread of flame, smoke and gases, and maintain the integrity of fire resistance rated walls, partitions, floors, and ceiling-floor assemblies, including through-penetrations and construction joints and gaps.a. Through-penetrations include the annular space around pipes, tubes, conduit, wires
18、, cables and vents.b. Construction joints include those used to accommodate expansion, contraction, wind, or seismic movement; firestopping material shall not interfere with the required movement of the joint.Gaps requiring firestopping include gaps between the curtain wall and the floor slab and be
19、tween the top of the fire-rated walls and the roof or floor deck above and at the intersection of shaft assemblies and adjoining fire resistance rated assemblies.1.2.2 Sequencing*NOTE: Edit this paragraph depending on whether existing insulation is to remain or be removed.*Coordinate the specified w
20、ork with other trades. Apply firestopping materials, at penetrations of pipes and ducts, prior to insulating, unless insulation meets requirements specified for firestopping. Apply firestopping materials. at building joints and construction gaps, prior to completion of enclosing walls or assemblies.
21、 Cast-in-place firestop devices shall be located and installed in place before concrete placement. Pipe, conduit or cable bundles shall be installed through cast-in-place device after concrete placement but before area is concealed or made inaccessible. Firestop material shall be inspected and appro
22、ved prior to final completion and enclosing of any assemblies that may conceal installed firestop.1.2.3 Submittals Requirements*NOTE: Projects designed to be LEED registered must include submittal for low-emitting materials; LEED credit EQ 4.1 VOC content of product, providing a maximum allowable VO

Projects not SECTION 07 84 00 Page 4Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-registering for LEED certification but are designed to LEED standards must still include VOC content requirements.*
24、a. Submit detail drawings including manufacturers descriptive data, typical details conforming to UL Fire Resistance or other details certified by another nationally recognized testing laboratory, installation instructions or UL listing details for a firestopping assembly in lieu of fire-test data o
25、r report. For those firestop applications for which no UL tested system is available through a manufacturer, a manufacturers engineering judgement, derived from similar UL system designs or other tests, shall be submitted for review and approval prior to installation. Submittal shall indicate the fi
26、restopping material to be provided for each type of application. When more than a total of 5 penetrations and/or construction joints are to receive firestopping, provide drawings that indicate location, “F“ “T“ and “L“ ratings, and type of application.b. Submit certificates attesting that firestoppi
27、ng material complies with the specified requirements. In lieu of certificates, drawings showing UL classified materials as part of a tested assembly may be provided. Drawings showing evidence of testing by an alternate nationally recognized independent laboratory may be substituted. For all intumesc
28、ent firestop materials used in through penetration systems, manufacturer shall provide certification from UL of passing the “Aging and Environmental Exposure Testing “ portion of UL 1479.c. Submit documentation of training and experience for Installer.d. Submit manufacturers representative certifica

30、ect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if t
31、he submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within t
32、he submittal tags may be used following the “G“ designation to indicate the approving authority.
