PART 1 GENERAL 1.1 REFERENCES NOTE: This paragraph is used to list the publications cited in the text of the guide specification. The publications are referred to in the text by basic designation only and listed in this paragraph by organization, designation, date, and title. Use the Reference Wizard's Check Reference feature when you add a RID outside of the Section's Reference Article to automatically place the reference in the Reference Article. Also use the Reference Wizard's Check Reference feature to update the issue dates. References not used in the text will automatically be deleted from this section of the project specification when you choose to reconcile references in the publish print process. The publications listed below form a part of this specification to the extent referenced. The publications are referred to within the text by the basic designation only.

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 the submittal item is not complex and can be reviewed through the Contractor’s 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 the submittal tags may be used following the "G" designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO" for District Office (Engineering Division or other organization in the District Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project Office. Codes following the "G" typically are not used for Navy, Air Force, and NASA projects. Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects. Government approval is required for submittals with a "G" designation; submittals not having a "G" designation are [for Contractor Quality Control approval.][for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government.] Submit the following in accordance with Section 01 33 00 SUBMITTAL PROCEDURES: _{SD-02 Shop Drawings} Submit installation drawings for _{Fireproof Plaster} in accordance with the paragraph entitled, "Application," of this section. _{SD-03 Product Data} Submit manufacturer's catalog data for _{Fireproof Plaster} showing applicable flame spread classification, fuel contribution, and smoke developed. _{SD-04 Samples} Not less than 0.2 kilogram 1/2 pound of _{Fireproofing Plaster} mix. _{SD-07 Certificates} Submit certificates for _{Fireproof Plaster} showing conformance with the ICC IBC, "International Building Code," "Requirements for Four-Hour Construction." _{SD-08 Manufacturer's Instructions} Submit manufacturer's instructions for _{Fireproof Plaster} including special provisions required to install equipment components and system packages. Indicate all detail impedances, hazards and safety precautions on drawings. 1.3 DELIVERY, HANDLING, AND STORAGE Deliver materials in original unopened packages bearing the name of the product, manufacturer's name, and the Underwriters Laboratories, Inc. label. Store materials off the ground, under cover, and away from damp surfaces and keep dry until ready to use. Discard all materials that has been exposed to water before use. PART 2 PRODUCTS 2.1 MATERIALS 2.1.1 _{Fireproof Plaster} Provide gypsum-vermiculite fire-proof plaster mix, consisting of one part gypsum to two parts vermiculite. Plaster must comply with ICC IBC, "International Building Code," "Requirements for 4-Hour Construction." Cohesion of the dry set material must be such that the fireproofing coat will not crack or delaminate when the structural [steel ]element is subjected to a downward deflection of 1/120 of the span. Minimum compressive strength requirement is not less than 485 kilopascal 70 pounds per square inch. When tested in accordance with ASTM E 84, the set and dry material must yield the following characteristics: Flame spread 10 Fuel contributed 5 Smoke developed 0 2.1.2 Water Use only potable water for mixing. PART 3 EXECUTION 3.1 INSTALLATION 3.1.1 General Requirements Apply fireproofing plaster as specified to those areas indicated on drawings. Install per details as indicated. 3.1.2 Application Application of _{fireproofing plaster} must be [pneumatic] [or] [and] [trowelled] in accordance with material manufacturer's written recommendations. Provide thickness of application as indicated and in compliance with the applicable codes to provide rated fireproofing when tested in accordance with ASTM E 119. Framing and furring must be as recommended by manufacturer for the installation of the fireproofing plaster thickness required or as indicated in the drawings. 3.2 ACCEPTANCE PROVISIONS After completion of fireproofing work, remove all application equipment. Clean all areas of ceilings, walls, and floors, adjacent or exposed to the operations of application of the fireproofing material, and other surfaces and finishes that may have been soiled by fireproofing materials. Remove any damaged or unacceptable portions of the fireproofing plaster and replace with new work at no additional cost to the Government.
