Indicate structural members t

20、hat do not require fireproofing, such as exterior structural peripheral members.The following information will be shown on the project drawings or detailed in this section:1. The extent and location of sprayed fire protection.2. Fire resistance rating of each structural component to receive fireproo

Fire protection other than that specified in this section for equivalent masonry, concrete or plaster fire protection on outside surfaces of exterior structural peripheral members.4.

24、 the International Conference of Building Officials, or the International Building Code published by the International Code Council.SECTION 07 81 00 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Thickness and rating must be specified for each

25、 fireproofing application not covered by a specified UL Design Number. However, the UL Design number is for a specific product; therefore, is indirectly being proprietary and would require justification for sole source.The roof deck designs should utilize systems that do not require the underside of

26、 the decking to receive spray-applied fireproofing. This may require specifying a thicker deck or a different system. Due to flexing of the deck, spray-applied fireproofing will eventually become loose and be of no value.*Fire resistance ratings shall be in accordance with the fire rated assemblies

27、listed in UL Fire Resistance. Proposed materials not listed in UL Fire Resistance shall have fire resistance ratings at least equal to the UL Fire Resistance ratings as determined by an approved independent testing laboratory, based on tests specified in UL 263 or ASTM E 119. Submit reports and test

28、 records, attesting that the fireproofing material conforms to the specified requirements. Each test report shall conform to the report requirements specified by the test method. For the underside of the decking use metal lath installed prior to the fireproofing material or Rigid Board Fireproofing

29、Material as outlined in the UL Fire Resistance Directory Volume 1. Apply fireproofing to structural steel members, with the following hourly fire resistance rating and in accordance with the following UL design or approved equivalent. Use unrestrained fire resistance ratings, unless the architect/en

34、ubmittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently

35、 important or complex in context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Resident Manageme

Show evidence that each fireproofing installer has had a minimum of 3 years experience in installing the specified type of fireproofing. Each installer of fireproofing material shall be trained, have

43、a minimum of 3 years experience and a minimum of three installations using fireproofing of the type specified. A manufacturers willingness to sell its products to the Contractor or installer does not infer qualification of the buyer.1.4.2 Pre-Installation MeetingHold a meeting with the installer, fi
