31、”. 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 important or complex in context of the project.For submittals requiring Government approval on Army projects, a code

32、 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 organizatio

33、n 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.SECTION 46 73 00.35 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license
