The importance of an item in the project should be one of the primary factors in determining if

25、a submittal for the item should be required.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 Contractors Quality

26、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

27、 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 SECTION 09 23 00 Page 5Provided by IHSNot for ResaleNo reprodu

35、erMaintain an ambient temperature of not less than 13 degrees C 55 degrees F continuously during plastering, and drying, and until occupancy heating conditions are established in the area. Maintain this temperature for not less than one week prior to the application of plaster. Provide regulated ven

36、tilation to prevent “sweatouts“ or “dry-outs.“ When the building is exposed to hot dry winds or day-to-night temperature differentials of 10 degrees C 20 degrees F or more, cover openings that are not glazed. Gypsum and related materials must conform to ASTM C 11. Provide permanent ventilation for s

37、paces enclosed by suspended ceilings as indicated.1.6 Gypsum Plaster Full Size SampleAfter selection of an acceptable texture, construct a sample panel wall separate from the building, minimum size of 8 _ ft 2400 _ mmin height, by 8 _ ft 2400 _ mm in length, using 150 mm6 inch metal studs, and gypsu

38、m board, metal lath and gypsum plaster. The sample wall must show all aspects of gypsum plaster work, including but not limited to, expansion joints, control joints, corner extrusions, electrical mechanical and fire sprinkler penetrations and casing beads. A sample of a control joint and extrusion b

39、utt joint must also be incorporated into the sample wall. Finish work must match the approved sample panel. Divide the panel into four equal quardrants with the expansion and control joints to show each phase of work, lath, scratch coat, brown coat, and finish coats. The Contractor shall protect the
