This type of decking will be specified ONLY as a Contractor
15、s option to other types of SECTION 03 55 16 Page 3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-decking since it is a proprietary product. Optional systems will be specified in other Sections and may be cast-in-place gypsum, light weight concrete,
16、expanded metal, or other competitive material suitable to the project.Gypsum plank decking is suitable for moderate temperature and humidity conditions, as recommended by the manufacturer. This type of decking is intended only for walking and for light construction live loads. The maximum allowable
17、superimposed load on the plank is 2.4 kPa (50 psf). Serviced equipment will be supported by structural framing members. Gypsum plank decking is not to be used for material storage. Ceiling suspended under plank decks will be hung from the steel frame or subpurlins, not from the plank itself.Designer
18、 should require materials, products and innovative construction methods and techniques which are environmentally sensitive, take advantage of recycling and conserve natural resources.*The gypsum plank deck system specified in this Section is a Contractors option to other systems specified in Section
19、s _. Provide gypsum plank deck systems which are the products of one manufacturer. Perform the work specified through experienced, qualified installers. Design of the decking system shall be for the dead load conditions and spans indicated; and a maximum allowable superimposed load on the plank of 2
20、.4 kPa 50 psf, to include live load and loads imposed by openings; work of other trades; and all loading and restraining conditions from fabrication, handling, and erection. Support equipment and ceiling by structural framing not from gypsum planks. Deflection shall not exceed L/240 of span. Provide
21、 floor decks that are 2 hour fire rating in accordance with ASTM E 119 fire test conditions.1.3 SUBMITTALS*NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals shou
22、ld 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
23、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 the submittal tags may be used following the “G“ designation to in
