Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates th

27、at the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not SECTION 42 23 13.00 40 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-complex and can be rev

28、iewed 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 the submittal tags may be used following the “G“

29、 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

30、“ 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“ designat
